    2003-11-01

    This article reviews constraints to household level animal source food production in developing countries and suggests solutions to some of these constraints. These constraints include land, labor, money, feed quality, water, disease, animal genetics, roles for animals beyond food production, grazing techniques and an understanding of the entire agricultural system at the household level. Better understanding of farming systems and the elements that comprise it which affect animal food production permits wise management of nutrient flows and enhanced sustainability. PMID:14672309

    Constraints have been traditionally used for computer animation applications to define side conditions for generating synthesized motion according to a standard, usually physically realistic, set of motion equations. The case of facial animation is very different, as no set of motion equations for f

  3. Gene-based vaccine development for improving animal production in developing countries. Possibilities and constraints

    International Nuclear Information System (INIS)

    For vaccine production, recombinant antigens must be protective. Identifying protective antigens or candidate antigens is an essential precursor to vaccine development. Even when a protective antigen has been identified, cloning of its gene does not lead directly to vaccine development. The fimbrial protein of Dichelobacter nodosus, the agent of foot-rot in ruminants, was known to be protective. Recombinant vaccines against this infection are ineffective if expressed protein subunits are not assembled as mature fimbriae. Antigenic competition between different, but closely related, recombinant antigens limited the use of multivalent vaccines based on this technology. Recombinant antigens may need adjuvants to enhance response. DNA vaccines, potentiated with genes for different cytokines, may replace the need for aggressive adjuvants, and especially where cellular immunity is essential for protection. The expression of antigens from animal pathogens in plants and the demonstration of some immunity to a disease like rinderpest after ingestion of these, suggests an alternative approach to vaccination by injection. Research on disease pathogenesis and the identification of candidate antigens is specific to the disease agent. The definition of expression systems and the formulation of a vaccine for each disease must be followed by research to establish safety and efficacy. Where vaccines are based on unique gene sequences, the intellectual property is likely to be protected by patent. Organizations, licensed to produce recombinant vaccines, expect to recover their costs and to make a profit. The consequence is that genetically-derived vaccines are expensive. The capacity of vaccines to help animal owners of poorer countries depends not only on quality and cost but also on the veterinary infrastructure where they are used. Ensuring the existence of an effective animal health infrastructure in developing countries is as great a challenge for the developed world as

  4. Application of gene-based technologies directed at commensal gut bacteria to solve animal productivity constraints in developing countries

    International Nuclear Information System (INIS)

    problems faced by microbial ecologists studying the gut ecosystem are the inevitable bias introduced by culture-based enumeration and characterization techniques, and the lack of a phylogenetically based classification scheme. These limitations can be overcome by the application of modern molecular techniques based on sequence comparisons of nucleic acids and used to provide genotypic characterization while at the same time providing a classification scheme which predicts natural evolutionary relationships. Importantly this molecular approach does not rely on cultivation but rather the analysis of community DNA, representing all resident microbes, extracted from intestinal samples. The powerful combination of molecular biology and Woese's new phylogeny has created the now recognized field of molecular microbial ecology. This is defined as the application of molecular technology, usually based on comparative nucleic acid sequence information, to identify specific microorganisms in the gut environment, to assign functional roles to these specific microorganisms, and to assess their significance or contribution to specific metabolic and physiological processes in the gastrointestinal tract. The advantages and limitations of various techniques employed for molecular microbial ecology studies will be reviewed in an effort to identify which gene-based technologies directed at commensal gut bacteria are most relevant and applicable to solving animal productivity constraints in developing countries. The use of these techniques has lead to major advances in our knowledge and will provide the first complete description of the gastrointestinal ecosystem. The latest and most powerful technologies revolutionizing microbiology are based on genomics - the mapping and sequencing of genomes and analysis of gene and genome function. Genomics refers to a suite of functional and comparative methods that capitalize on the availability of entire or high coverage draft sequence. More than 100

  5. Building for animal production

    International Nuclear Information System (INIS)

    In order to limit the radiation dose to persons working with animal husbandry in severe fallout situations, it was considered necessary to make an inventory of the Swedish livestock buildings as to number, location, use and size. These data as well as data on geometry of buildings, building material and thickness of the material in walls and roofs are given in the present work. On the basis of the mentioned data, calculations were made of the shielding factors of different types of livestock buildings. The collected data can also be used in preparedness planning in relation to housing facilities for livestock and location and size of animal production in situations of crises or war. The calculations show shielding factors for different types of livestock buildings of normal ground area within the range of 0.18-0.71. The higher value indicates a fairly poor shielding effect. The inventory and the calculations show that in those regions in Sweden where the main part of the livestock is managed, the types of buildings are, however, characterized by radiation shielding factors of 0.3-0.4. Calculation were also made of the radiation level inside the buildings following decontamination of roofs or of surrounding ground. Ground decontamination only, i.e., removal of the upper contaminated surface layer, will reduce the radiation level inside the building. For most buildings the radius of the surrounding area to be decontaminated has to be 15-30 times larger than the width of the building in order to achieve a 50 percentage reduction of the radiation level inside the building. For buildings of medium or large size and with thick walls the radiation contribution from the roof is greater than the radiation from the ground, and regardless of the size of the ground areas decontaminated the radiation level inside these buildings will only be reduced by 20-30%. 15 refs, 11 figs, 14 tabs

    Full Text Available Cytogenetics applied to domestic animals is a useful biotechnology to be applied in the genetic improvement of livestock. Indeed, it can be used to select reproducers free chromosome abnormalities which are responsible for abnormal body conformation (aneuploidy, lower fertility (balanced chromosome abnormalities or sterility (sex chromosome abnormalities. Cytogenetics may also be applied to assess environmental pollution by studying animals living in hazardous areas and using them as biological indicators (sentinels. Chromosomes also represent optimal biological structures to study the evolution among related (bovids and unrelated (bovidshumans species, especially using comparative FISH-mapping which is one of the most powerful tools to establish the correct order of loci along chromosomes. These comparisons allow us to transfer useful information from richer genomes (human to those of domestic animals. Moreover, the use of specific molecular markers and the FISH-technique on both mitotic and extended (fiber-FISH chromosomes, has heralded a new era of cytogenetics, allowing swift extension of genetic physical maps, better anchoring of both linkage and RH-maps to specific chromosome regions, and use in a variety of applications (clinical cases, embryo and sperm analyses, evolution. In this study a brief review of these fields of the animal cytogenetics is presented.

  7. Radioactivity transfer to animal products

    International Nuclear Information System (INIS)

    Information on the behaviour of strontium, caesium, ruthenium, plutonium and americium in a range of domestic animals is reviewed to form a basis for the specification of time-dependent mathematical models describing uptake, distribution and retention in various domestic animals. Transfer factors relating concentration in animal product to daily radioactivity intake are derived after 100 d continuous intake and at equilibrium. These transfer factors are compared with the available published literature and used as a basis for the derivation of feedingstuff conversion factors relating limiting concentrations in animal feedingstuffs to limiting concentrations in human foodstuffs for application to animals receiving commercial feedingstuffs after a nuclear accident. Recommended transfer factors for animal products in conditions of continuous discharge and models for application to field conditions after a nuclear accident are also presented. Transfer of caesium to animal products is more effective than that for the other elements considered here. Transfer to meat of lamb, fattening pig, and chickens is generally more effective than that for other animals and other products

  8. Sustainable Improvement of Animal Production and Health

    International Nuclear Information System (INIS)

    The world's poorest people, some one billion living mostly in Africa and Asia, depend on livestock for their day-to-day livelihood. To reduce poverty, fight hunger and ensure global food security, there is an urgent need to increase livestock production in sustainable ways. However, livestock production in developing countries is constrained by low genetic potential of the animals, poor nutrition and husbandry practices and infectious diseases. Nuclear techniques, when applied in conjunction with conventional methods, can identify constraints to livestock productivity as well as interventions that lead to their reduction or elimination in ways that are economically and socially acceptable. The challenge is how best to exploit these techniques for solving problems faced by livestock keepers within the many agricultural production systems that exist in developing countries and demonstrating their advantages to owners, local communities and government authorities. This publication is a compilation of the contributions emanating from an international Symposium on Sustainable Improvement of Animal Production and Health organised by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in cooperation with the Animal Production and Health Division of FAO. It provides invaluable information not only on how nuclear and related techniques can be used to support sustainable livestock production systems, but also about the constraints and opportunities for using these techniques in developing countries; it also attempts to identify specific research needs and gaps and new options for using these techniques for solving established and emerging problems. As such, it is hoped that the information presented and suggestions made will provide valuable guidance to scientists in both the public and private sectors as well as to government and institutional policy and decision makers. The Symposium comprised a plenary session and four thematic sessions, covering (i

  9. Pair Production Constraints on Superluminal Neutrinos Revisited

    Energy Technology Data Exchange (ETDEWEB)

    Brodsky, Stanley J.; /SLAC; Gardner, Susan; /Kentucky U.

    2012-02-16

    We revisit the pair creation constraint on superluminal neutrinos considered by Cohen and Glashow in order to clarify which types of superluminal models are constrained. We show that a model in which the superluminal neutrino is effectively light-like can evade the Cohen-Glashow constraint. In summary, any model for which the CG pair production process operates is excluded because such timelike neutrinos would not be detected by OPERA or other experiments. However, a superluminal neutrino which is effectively lightlike with fixed p{sup 2} can evade the Cohen-Glashow constraint because of energy-momentum conservation. The coincidence involved in explaining the SN1987A constraint certainly makes such a picture improbable - but it is still intrinsically possible. The lightlike model is appealing in that it does not violate Lorentz symmetry in particle interactions, although one would expect Hughes-Drever tests to turn up a violation eventually. Other evasions of the CG constraints are also possible; perhaps, e.g., the neutrino takes a 'short cut' through extra dimensions or suffers anomalous acceleration in matter. Irrespective of the OPERA result, Lorentz-violating interactions remain possible, and ongoing experimental investigation of such possibilities should continue.

  10. AUTOMATIC APPROACH TO PRODUCT CONCEPTUAL DESIGN BASED ON CONSTRAINT NETWORK

    2004-01-01

    Product design is considered as the constraint satisfaction problem (CSP), and a new design approach basedon constraint network is proposed and applied to make design automatic partially. By means of constraint extraction, constraint network construction and operation, constraint chains are acquired, and then the conceptual design scheme can be got by decoding the information stored in the design constraint chains, which provides a novelty method for mechanical product design automation. Shearing mechanism of shearing machine has been designed by this way.

    In order to gain new insights into the gauge field couplings in the early universe, we consider the constraints on gauge field production during inflation imposed by requiring that their effect on the CMB anisotropies are subdominant. In particular, we calculate systematically the bispectrum...... of the primordial curvature perturbation induced by the presence of vector gauge fields during inflation. Using a model independent parametrization in terms of magnetic non-linearity parameters, we calculate for the first time the contribution to the bispectrum from the cross correlation between the inflaton...

    Full Text Available Poor livestock health services remain one of the main constraints to livestock production in many developing countries, including Ethiopia. A study was carried out in 11 districts of North Gondar, from December 2011 to September 2012, with the objective of identifying the existing status and constraints of animal health service delivery, and thus recommending possible alternatives for its sustainable improvement. Data were collected by using pre-tested questionnaires and focus group discussion. Findings revealed that 46.34% of the responding farmers had taken their animals to government veterinary clinics after initially trying treatments with local medication. More than 90.00% of the clinical cases were diagnosed solely on clinical signs or even history alone. The antibacterial drugs found in veterinary clinics were procaine penicillin (with or without streptomycin, oxytetracycline and sulphonamides, whilst albendazole, tetramisole and ivermectin were the only anthelmintics.

    This article deals with carbon dioxide production from farm animals; more specifically, it addresses the possibilities of using the measured carbon dioxide concentration in animal houses as basis for estimation of ventilation flow (as the ventilation flow is a key parameter of aerial emissions from...... animal houses). The investigations include measurements in respiration chambers and in animal houses, mainly for growing pigs and broilers. Over the last decade a fixed carbon dioxide production of 185 litres per hour per heat production unit, hpu (i.e. 1000 W of the total animal heat production at 20o......C) has often been used. The article shows that the carbon dioxide production per hpu increases with increasing respiration quotient. As the respiration quotient increases with body mass for growing animals, the carbon dioxide production per heat production unit also increases with increased body mass...

    Full Text Available In terms of foreign trade, in Romania there were some major changes over the past 20 years. In this paper we have focused on the Romanian external trade. The products which have been taken into account were live animals and animal products. Thus, we have made an analyse on the Romanian imports and exports at the global level and at the European level. Focused on the animal products, on the global level, there were registered major differences during the first seven years in the analysed period. Breaking by branches, we have pointed out huge distinctions between imports and exports, where the balance of trade was completely negative. Meanwhile, to have a good view on the international trade there were made links, based on some indexes between imports, exports, GDP and investments.

  4. Animal movement constraints improve resource selection inference in the presence of telemetry error

    Brost, Brian M.; Hooten, Mevin B.; Hanks, Ephraim M.; Small, Robert J.

    2016-01-01

    Multiple factors complicate the analysis of animal telemetry location data. Recent advancements address issues such as temporal autocorrelation and telemetry measurement error, but additional challenges remain. Difficulties introduced by complicated error structures or barriers to animal movement can weaken inference. We propose an approach for obtaining resource selection inference from animal location data that accounts for complicated error structures, movement constraints, and temporally autocorrelated observations. We specify a model for telemetry data observed with error conditional on unobserved true locations that reflects prior knowledge about constraints in the animal movement process. The observed telemetry data are modeled using a flexible distribution that accommodates extreme errors and complicated error structures. Although constraints to movement are often viewed as a nuisance, we use constraints to simultaneously estimate and account for telemetry error. We apply the model to simulated data, showing that it outperforms common ad hoc approaches used when confronted with measurement error and movement constraints. We then apply our framework to an Argos satellite telemetry data set on harbor seals (Phoca vitulina) in the Gulf of Alaska, a species that is constrained to move within the marine environment and adjacent coastlines.

    Geologic reasons indicate that the dominant position of the Middle East as a source of conventional petroleum will not be changed by new discoveries elsewhere. The share of world crude oil production coming from the Middle East could increase, within 10 to 20 years, to exceed 50 percent, under even modest increases in world consumption. Nonconventional resources of oil exist in large quantities, but because of their low production rates they can at best only mitigate extant trends. Increased production of natural gas outside the United States, however, offers an opportunity for geographically diversified energy supplies in the near future. PMID:17779130

    Chicken production has a major role in the economy of developing countries and backyard production is particularly important to women. Several programmes, in Ethiopia and elsewhere, have attempted to improve chicken production as a means to reduce poverty. A key constraint to chicken production identified by farmers is disease. This study used participatory rural appraisal methods to work with chicken-keepers in order to prioritise chicken diseases, place these within the context of other production constraints, and to explore perceptions of disease risk factors and biosecurity measures. The study, focused on Debre Zeit, Ethiopia, included 71 poultry keepers (41 backyard and 30 semi-intensive chicken producers). Although women played an important role in backyard production systems, semi-intensive farms were more likely to be controlled by men. Participants identified 9 constraints to production: 7 of 8 groups of backyard producers and 15/31 semi-intensive producers ranked diseases as the most important constraint to chicken production. In contrast to previous reports, farmers in both groups had considerable knowledge of diseases and of factors affecting disease risk. Both groups, but particularly semi-intensive producers, highlighted access to feed as a constraint. Many of the challenges faced by both groups were associated with difficulty accessing agricultural and veterinary inputs and expertise. Whilst many of the constraints identified by farmers could be viewed as simply technical issues to be overcome, we believe it is important to recognise the social factors underpinning what are, in reality, relatively modest technical challenges. The low involvement of women in semi-intensive production needs to be recognised by poultry development schemes. Provision needs to be made to allow access to inputs for a wide range of business models, particularly for those, such as women, who have limited access to the capital to allow them to make the jump from backyard to

A baseline survey study was conducted in central, eastern and western Kenya between September and December 2012, to determine the farmers’ preferences of sweetpotato varieties, production constraints and farmers’ coping strategies. A structured questionnaire was randomly administered to 345 farmers in five counties. Data on households demographics, sweetpotato varieties grown, sources of seed, cultural practices, and production constraints were collected and analysed using statistical package for social scientists (SPSS. Results indicated that 60% of the farmers interviewed were women and family sizes varied between 3-5 persons in 55% of the households. Farm sizes ranged 0.41-0.8 ha with 90% of sweetpotato being grown on 0.24 ha or less. The main food crops grown on the surveyed farms included maize, beans, sweetpotato, cassava, sorghum, and pigeon peas, while the main cash crops were; kale, banana, sugarcane, bean, maize, sweetpotato and groundnut. The average sweetpotato yield on the farms surveyed ranged from 5.5-7.4 t ha-1. The preferred sweetpotato varieties were Vitaa, Kembu 10, and Kabonde because they were orange fleshed with high beta carotene. Production constraints in the three regions were basically similar, with 35% of the farmers identifying weevils as the major pest, and sweetpotato virus disease (SPVD as the major disease. Drought was identified by 28% of the farmers as a major production constraint. Farmers indicated the use of clean seed, high yielding varieties, high planting density, and manure application as some of the strategies they used to cope with the production constraints. To improve sweetpotato production in Kenya, these production constraints need to be

  20. Soil, pasture and animal product quality

    Full Text Available The management of pasture, through the use of appropriate stocking rates and grazing systems, influences the feeding behaviour of the animals. The impact of animal behaviour on vegetation can be of great importance for the sustainability of pastures and mantaining their biodiversity. Indeed, a different response in terms of quality of animal products is mediated by the ability of animals to concentrate or transform grass components, according to the characteristics of the soil. The herbage ingested by animals provides them with compounds with aromatic characteristics, such as terpenes, and with functional properties beneficial for human health, such as carotenoids, vitamins, polyphenols and polyunsatured fatty acids. The combination of different ecological conditions on different soils through specific management practices determines the differentiation of several pasture vegetation types, a unique patrimony of great value in terms of biodiversity and capability to sustain local production, also important because of their own high added value. This review deals with pasture management aimed at conserving the soil and reducing gas emissions, and takes into consideration the quality of animal products as a result of such management.

  2. Nuclear techniques in Australian animal production

    International Nuclear Information System (INIS)

    In tropical and sub-tropical regions, the production of domestic animals is frequently depressed by the climatic and ecological conditions. These negative effects can be overcome to a great extent by improved methods of animal and land management. In animal research, nuclear techniques are playing an important role in the study of different aspects of nutrition, metabolism, reproduction and health of domestic animals. In response to the need expressed by Member States for more information on these techniques, the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture and the IAEA's Division of Technical Assistance organized a study tour to Australia, a country which has developed considerable expertise in agricultural and animal research. The purpose of the study tour was to enable veterinary and animal scientists and administrators from developing countries in Asia and the Far East to observe at first hand the ways in which animal production, particularly meat, milk and wool, can be increased in tropical and sub-tropical areas. Fourteen senior scientists and research directors from seven Asian countries (Bangladesh, India, Republic of Korea, Malaysia, Philippines, Sri Lanka and Thailand) participated. The counterpart organizations in Australia were the Australian Development Assistance Agency (ADAA) and the Commonwealth Scientific and Industrial Research Organization (CSIRO). The chief programmer and co-ordinator of the study tour was John E. Vercoe, officer-in-charge of CSIRO's Tropical Cattle Research Centre in Rockhampton, and a former IAEA staff member. The tour was financed by the United Nations Development Programme. The participants visited research facilities of universities, national and state laboratories and commercial cattle producers. The tour started at Sydney and proceeded north along the east coast of Australia to Townsville. On the way, major stops were made in Armidale, Grafton, Wollongbar, Brisbane and Rockhampton. In Rockhampton, a

    Full Text Available The study was conducted to review the situation of dairying in Marathwada with the objectives to identify major constraints of the dairy farmers in adapting the recommended animal husbandry practices. The survey work was carried out for the milk pocket areas in eight districts of the Marathwada region. Out of 144 dairy farmers, 109 farmers cared crossbred animals; 65 out of 85 dairy farmers adapted cooling arrangement to cross-bred cows during summer; 35 of 45 adapted washing their animals during summer; 98 of 230 dairy farmers followed vaccination to their animals; 45 of 230 dairy farmers followed de-worming their animals; 37 of 230 adapted to control the ecto-parasite; 65 of 230 reacted for removal old debris; 105 of 230 dairy farmers adapted A.I. policy and only 88 of 230 dairy farmers were positive for the animals insurance. Higher proportion of the farmers has accepted the importance of crossbred cows. Higher numbers of farmers have positive response to cool their animals. Significantly more numbers of farmers did not care to vaccinate and accept other health measures for their animals. Non-significant differences between dairy farmers adapting and non-adapting A.I. practices were recorded while significant (P>0.01 difference was observed between the farmers adapting and not adapting the insurance policy.

    Livestock and poultry producers face a number of challenges including pressure from the public to be good environmental stewards and adopt welfare-friendly practices. In response, producers often implement practices beyond those required for regulatory compliance to meet consumer demands. However, environmental stewardship and animal welfare may have conflicting objectives. Examples include pasture-based dairy and beef cattle production where high-fiber diets increase methane emissions compared with grain feeding practices in confinement. Grazing systems can contribute to nitrate contamination of surface and groundwater in some areas of the world where grazing is the predominant land use. Similarly, hoop housing for sows, an alternative to indoor gestation crates, can increase the risk of nutrient leaching into soil and groundwater. Direct air emissions may also increase with unconfined animal production as a result of less opportunity to trap and treat emissions, as well as the result of increased cage space and greater surface area per mass of excreta. Coupling welfare-friendly and organic production practices may require greater nutrient inputs to reach the same production end point, resulting in less efficient nutrient use and greater losses to the environment. Dual systems might additionally increase environmental contamination by pathogens. When swine are housed in welfare-friendly huts, Salmonella may cycle more freely between swine and their environment; however, population numbers of pathogenic bacteria may not be different between the indoor and outdoor systems evaluated. Alternatively, these dual purpose systems may reduce antibiotic and hormonal releases to the environment. Finally, intensity of resource use may be different under welfare-friendly and organic practices. In most situations, welfare-friendly production will require more land area per animal or per unit of product. Energy inputs into such systems, from feed production to rearing to product

    Increases in animal products consumption and the associated environmental consequences have been a matter of scientific debate for decades. Consequences of such increases include rises in greenhouse gas emissions, growth of consumptive water use, and perturbation of global nutrients cycles. These consequences vary spatially depending on livestock types, their densities and their production system. In this letter, we investigate the spatial distribution of embodied crop calories in animal products. On a global scale, about 40% of the global crop calories are used as livestock feed (we refer to this ratio as crop balance for livestock) and about 4 kcal of crop products are used to generate 1 kcal of animal products (embodied crop calories of around 4). However, these values vary greatly around the world. In some regions, more than 100% of the crops produced is required to feed livestock requiring national or international trade to meet the deficit in livestock feed. Embodied crop calories vary between less than 1 for 20% of the livestock raising areas worldwide and greater than 10 for another 20% of the regions. Low values of embodied crop calories are related to production systems for ruminants based on fodder and forage, while large values are usually associated with production systems for non-ruminants fed on crop products. Additionally, we project the future feed demand considering three scenarios: (a) population growth, (b) population growth and changes in human dietary patterns and (c) changes in population, dietary patterns and feed conversion efficiency. When considering dietary changes, we project the global feed demand to be almost doubled (1.8-2.3 times) by 2050 compared to 2000, which would force us to produce almost equal or even more crops to raise our livestock than to directly nourish ourselves in the future. Feed demand is expected to increase over proportionally in Africa, South-Eastern Asia and Southern Asia, putting additional stress on these

    The recombinant production of therapeutic proteins for human diseases is currently the largest source of innovation in the pharmaceutical industry. The market growth has been the driving force on efforts for the development of new therapeutic proteins, in which transgenesis emerges as key component. The use of the transgenic animal platform offers attractive possibilities, residing on the low production costs allied to high productivity and quality of the recombinant proteins. Although many strategies have evolved over the past decades for the generation of transgenic founders, transgenesis in livestock animals generally faces some challenges, mainly due to random transgene integration and control over transgene copy number. But new developments in gene editing with CRISPR/Cas system promises to revolutionize the field for its simplicity and high efficiency. In addition, for the final approval of any given recombinant protein for animal or human use, the production and characterization of bioreactor founders and expression patterns and functionality of the proteins are technical part of the process, which also requires regulatory and administrative decisions, with a large emphasis on biosafety. The approval of two mammary gland-derived recombinant proteins for commercial and clinical use has boosted the interest for more efficient, safer and economic ways to generate transgenic founders to meet the increasing demand for biomedical proteins worldwide.

Meat is excelent source of proteins with high biological value.The proteins from meat are of high quality because they contain high share of essencial amino acids which are necessary for human organism. Polyunsaturated fatty acids, esspecialy those from ω3 group, became very importat to human nutritionists because they have significant role in prevention of stress induced deseases and of those induced by improper diets. New findings from western industrial countries point out the fact that longer intake of LA (ω-6 with relative “deficiency” of ω-3 is the main risk factor in occurence of cancer, coronary deseases (CHD, cerebrovascular deseases (CVD and alergic hyperactivity; not cholesterol as was considered till now. Therefore it is important to reduce the ω-6 / ω-3 acids ratio in meat and milk using some feedstufs in diets of animals. Dairy products contribute to health throughout life. Epidemiological researches as well as studies in animals and humans indicate that dairy food and/or their components have a protective effect against cancer. The potential anticancer agents identified so far in dairy foods include conjugated linoleic acid (CLA, calcium, vitamin D, sphingomyelin, butyric acid, ether lipids, protein and lactic acid bacteria. Milk is exclusive source of nutrients for the young and it also represents a high grade source of dietary nitrogen and indispensable amino acids for adults. Consumers are increasing looking for animal products, which could prevent disease or illness.Keywords: animal products, polyunsaturated fatty acids, meat, milk, nutrients.

    As we move into the second half of 1998, it is appropriate to look forward to 1999 which will see the commencement of four new FAO/IAEA Co-ordinated Research Projects (CRP) and the initiation of new round of biennium support for the Agency's programme of Technical C-operation (TC). The technical direction of support through these two activities reflects the process that was begun with the external review of the animal production and heath Sub-programme in 1996. Thus in the animal health field this year we have started three new CRPs on rinderpest, contagious bovine pleuropneumonia (CBPP) and Newcastle Disease, and in 1999 we will start a new CRP on developing techniques for separating foot-and-mouth disease (FMD) vaccinated animals from those naturally infected. In the animal production field we will start new CRPs in 1999 on purine derivative analysis in urine, and on tannins whilst in veterinary drug residue analysis the first CRP will commence, again in 1999.

  17. Impact of animal diseases on livestock productivity and economic losses

    International Nuclear Information System (INIS)

    The most serious impact of animal disease on livestock productivity in developing countries derives from its effect on overall livestock production and trade development rather than from the direct losses it causes. The global importance of major infectious diseases such as foot and mouth disease, rinderpest and African swine fever is reviewed. The impact of major livestock diseases in tropical Africa on livestock productivity and economic losses is analysed, and the importance of in-depth analysis of the disease impact on livestock and rural development is stressed. Lack of diagnosis facilities that are needed to acquire reliable information on the distribution of disease is often a major constraint to cost-benefit analysis of control options. However, enough evidence exists to substantiate the fact that improved disease control is a prerequisite for progress towards increased productivity based on the adoption of more intensive production systems and use of animals of improved genotype. Veterinary services in developing countries are at various stages of development, and the priority order of infra-structure, manpower and technological development for disease control programmes should be carefully planned and be based on socio-economic, cost-benefit and feasibility studies.

  1. Importance of animal feed resources in developing countries and current constraints on their utilization

    International Nuclear Information System (INIS)

    Inadequacy and poor utilization of animal feed resources are the main limiting factors on animal production in most developing countries. The bulk of ruminant foodstuffs consists of poor quality fodder, such as pasture and rangeland grass, crop residues and fibrous by-products. It is very rarely possible to use cereals as supplements, since most developing countries at present need to import cereals for human consumption. This has not prevented many development agencies from recommending that cereals and other concentrate feeds be imported to boost monogastric production, reproducing the model developed for temperate countries where there is a cereal surplus. In most cases, the types of feed available locally do not allow high levels of individual animal performance. However, this does not mean that it is impossible to improve animal production in developing countries. During the last two decades, much research on animal nutrition has been successfully conducted and the results are being applied in practice. The most significant of these concern the utilization by animals of sugar-cane and its by-products, the use of non-conventional animal feeds and the treatment of straw and other fibrous materials. In all cases, supplements are required. Livestock feeding systems could also be improved if it were possible to use more of those by-products which are at present exported. New livestock feeding strategies must be developed based on currently or potentially available local resources. It is more logical and profitable for developing countries to adapt animal production systems to available feed resources than vice versa. (author)

  2. Biophysical constraints on gross primary production by the terrestrial biosphere

    2014-02-01

    Full Text Available Persistent divergences among the predictions of complex carbon cycle models include differences in the sign as well as the magnitude of the response of global terrestrial primary production to climate change. This and other problems with current models indicate an urgent need to re-assess the principles underlying the environmental controls of primary production. The global patterns of annual and maximum monthly terrestrial gross primary production (GPP by C3 plants are explored here using a simple first-principles model based on the light-use efficiency formalism and the Farquhar model for C3 photosynthesis. The model is driven by incident photosynthetically active radiation (PAR and remotely sensed green vegetation cover, with additional constraints imposed by low-temperature inhibition and CO2 limitation. The ratio of leaf-internal to ambient CO2 concentration in the model responds to growing-season mean temperature, atmospheric dryness (indexed by the cumulative water deficit, ΔE and elevation, based on optimality theory. The greatest annual GPP is predicted for tropical moist forests, but the maximum (summer monthly GPP can be as high or higher in boreal or temperate forests. These findings are supported by a new analysis of CO2 flux measurements. The explanation is simply based on the seasonal and latitudinal distribution of PAR combined with the physiology of photosynthesis. By successively imposing biophysical constraints, it is shown that partial vegetation cover – driven primarily by water shortage – represents the largest constraint on global GPP.

    The effects produced by fission products in the organism of dairy cattle are considered. The presence of radionuclides in the animal body leads to the danger of radioactive contamination of milk and may result in the loss of milk productivity and reproductive capacity of the irradiated animals or even in their death. Of greatest practical interest is an experimental evaluation of the intake of fission products, since, on the one hand, milk is one of the basic and valuable foods and, on the other, it is the principal source of biologically dangerous radionuclides in human diet

The consultants' meeting that we held during 2001 (http://www.iaea.org/programmes/nafa/d3/public/ gene-technologies.pdf) provided us with the answers. We have subsequently discussed these concepts further with FAO, ILRI and other partners, and have planned a series of activities over the next two years to facilitate the transition of our Sub-programme. The first is an FAO/IAEA International Symposium on 'Applications of Gene Based Technologies for Improving Animal Production and Health in Developing Countries' which will be held here in Vienna from 6 to 10 October 2003. The official announcement is included in this Newsletter. This will be followed by three inter-regional training courses, to be held during 2004 and 2005, to train scientists in developing countries on the molecular techniques currently being used in the fields of animal nutrition, genetics and disease diagnosis. Subsequently, four new CRPs will be initiated during 2005-2006, dealing with (a) rumen molecular techniques for predicting and enhancing productivity; (b) manipulation of nutrition in utero to alter gene expression; (c) characterization of small ruminant genetic resources aimed at selection for parasite resistance; and (d) improvement of diagnostic tests for African Swine Fever to assist in molecular epidemiology. The announcements for the first two have already appeared in previous Newsletters and that for the third will be in the next issue.

    Full Text Available Many animal studies have been performed with krill oil (KO and this review aims to summarize their findings and give insight into the mechanism of action of KO. Animal models that have been used in studies with KO include obesity, depression, myocardial infarction, chronic low-grade and ulcerative inflammation and are described in detail. Moreover, studies with KO in the form of krill powder (KP and krill protein concentrate (KPC as a mix of lipids and proteins are mentioned and compared to the effects of KO. In addition, differences in tissue uptake of the long-chain omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA, when delivered in either phospholipid or triglyceride form, are addressed and the differential impact the delivery form has on gene expression profiles is explained. In our outlook, we try to highlight the potential of KO and KP supplementation in clinical settings and discuss health segments that have a high potential of showing krill product specific health benefits and warrant further clinical investigations.

  8. Animal production and health newsletter, No. 51, January 2010

    International Nuclear Information System (INIS)

    As 2010 is dawning on us, I want to look forward and highlight some of the exciting new nuclear and nuclear related areas that we think will play an important role in the near future. The main constraint to livestock production in many tropical regions of Africa, Asia and Latin America is the scarcity and fluctuations in quality and quantity of the year-around supply of feeds. Animal productivity is restricted by the low nitrogen and high fibre content of the native grasses and crop residues, which form the basis of the diets in these regions. An additional consequence of this poor diet in ruminants is the increased production of methane compared with ruminants fed on better quality forages. Studies on rumen metabolism using isotopes of carbon, hydrogen, sulphur, phosphorus and nitrogen have revealed how the ruminal microbial flora can change depending on the type of forage ingested. In addition, certain plant metabolites reduce the microbial population thereby improving efficiency of feed utilization by up to 10 per cent. The future application of this strategy is that the modulation of fermentation can reduce methane production, hence mitigating greenhouse gas emissions

  9. Ammonium photo-production by heterocytous cyanobacteria: potentials and constraints.

    Grizeau, Dominique; Bui, Lan Anh; Dupré, Catherine; Legrand, Jack

    2016-08-01

    Over the last decades, production of microalgae and cyanobacteria has been developed for several applications, including novel foods, cosmetic ingredients and more recently biofuel. The sustainability of these promising developments can be hindered by some constraints, such as water and nutrient footprints. This review surveys data on N2-fixing cyanobacteria for biomass production and ways to induce and improve the excretion of ammonium within cultures under aerobic conditions. The nitrogenase complex is oxygen sensitive. Nevertheless, nitrogen fixation occurs under oxic conditions due to cyanobacteria-specific characteristics. For instance, in some cyanobacteria, the vegetative cell differentiation in heterocyts provides a well-adapted anaerobic microenvironment for nitrogenase protection. Therefore, cell cultures of oxygenic cyanobacteria have been grown in laboratory and pilot photobioreactors (Dasgupta et al., 2010; Fontes et al., 1987; Moreno et al., 2003; Nayak & Das, 2013). Biomass production under diazotrophic conditions has been shown to be controlled by environmental factors such as light intensity, temperature, aeration rate, and inorganic carbon concentration, also, more specifically, by the concentration of dissolved oxygen in the culture medium. Currently, there is little information regarding the production of extracellular ammonium by heterocytous cyanobacteria. This review compares the available data on maximum ammonium concentrations and analyses the specific rate production in cultures grown as free or immobilized filamentous cyanobacteria. Extracellular production of ammonium could be coupled, as suggested by recent research on non-diazotrophic cyanobacteria, to that of other high value metabolites. There is little information available regarding the possibility for using diazotrophic cyanobacteria as cellular factories may be in regard of the constraints due to nitrogen fixation. PMID:25613641

  10. USE OF ELECTROLYZED WATER IN ANIMAL PRODUCTION

    Full Text Available The paper deals with the possibility to use the properties of electrolyzed water to disinfect breeding halls and to water animals. The aim of the research was to find out whether elektrolyzed water used for desinfication of breedings hall and watering of animals influences selected indicators of the meat quality. Electrolyzed water is produced in a patent-protected device Envirolyte that produces biocide solution using potable water with added NaCl. The technology of production guarantees the product is entirely ecological, biologically fully degradable, non-toxic that can replace traditional chemical agents. Possibilities of disinfection using this solution have been verified directly in stables at the interval of 20, 40, 60 min. after application. Staphylococci and streptococci and enterococci were inactive always after 60 minutes of effect. There was significant decrease in the number of total number of microorganisms. Further, the solution of electrolyzed water was used to water poultry; and the affect on some of the properties of poultry meat, changes in pH, colour and loss of water (dripping in particular, was observed. Testing was carried out under working conditions in two breeding halls at a time and the technology of electrolyzed water to disinfect premises and to water chickens was used in one of the halls. When the chickens were slaughter mature, the poultry was slaughtered at the standard slaughterhouse and samples (127 pieces were taken in order to measure pH, colour and loss of water (dripping. The values of pH, colour and loss of water (dripping ascertained, processed by the T-test did not confirm the hypothesis of the assumed possible differences in occurrence of critical values of these indicators in both groups observed.

    2015-02-01

    This study evaluated pig production practices by smallholder farmers in two distinct production systems geared towards addressing their constraints and prospects for improvement. The production systems evaluated were semi-intensive and extensive and differed in remoteness, market access, resource availability and pig production intensity. Data were collected using structured questionnaires where a total of 102 pig farmers were interviewed. Qualitative and quantitative research methods were employed to define the socioeconomic characteristics of the production systems, understanding the different roles that pigs play, marketing systems and constraints to production. In both systems, regular cash income and insurance against emergencies were ranked as the main reasons for rearing pigs. Marketing of pigs was mainly driven by the type of production operation. Finances, feeds and housing were identified as the major constraints to production. The study provides important parameters and identifies constraints important for consideration in design of sustainable production improvement strategies. Feeding challenges can be improved through understanding the composition and proper utilization of local feed resources. Provision of adequate housing would improve the stocking rates and control mating. PMID:25448534

    Companion animals comprise a wide variety of species, including dogs, cats, horses, ferrets, guinea pigs, reptiles, birds and ornamental fish, as well as food production animal species, such as domestic pigs, kept as companion animals. Despite their prominent place in human society, little is known about the role of companion animals as sources of viruses for people and food production animals. Therefore, we reviewed the literature for accounts of infections of companion animals by zoonotic viruses and viruses of food production animals, and prioritized these viruses in terms of human health and economic importance. In total, 138 virus species reportedly capable of infecting companion animals were of concern for human and food production animal health: 59 of these viruses were infectious for human beings, 135 were infectious for food production mammals and birds, and 22 were infectious for food production fishes. Viruses of highest concern for human health included hantaviruses, Tahyna virus, rabies virus, West Nile virus, tick-borne encephalitis virus, Crimean-Congo haemorrhagic fever virus, Aichi virus, European bat lyssavirus, hepatitis E virus, cowpox virus, G5 rotavirus, influenza A virus and lymphocytic choriomeningitis virus. Viruses of highest concern for food production mammals and birds included bluetongue virus, African swine fever virus, foot-and-mouth disease virus, lumpy skin disease virus, Rift Valley fever virus, porcine circovirus, classical swine fever virus, equine herpesvirus 9, peste des petits ruminants virus and equine infectious anaemia virus. Viruses of highest concern for food production fishes included cyprinid herpesvirus 3 (koi herpesvirus), viral haemorrhagic septicaemia virus and infectious pancreatic necrosis virus. Of particular concern as sources of zoonotic or food production animal viruses were domestic carnivores, rodents and food production animals kept as companion animals. The current list of viruses provides an objective

  14. Dust production in debris discs: constraints on the smallest grains

    CERN Document Server

    Thebault, Philippe

    2016-01-01

    The surface energy constraint puts a limit on the smallest fragment $s_{surf}$ that can be produced after a collision. Based on analytical considerations, this mechanism has been recently identified as been potentially able to prevent the production of small dust grains in debris discs and cut off their size distribution at sizes larger than the blow-out size. We numerically investigate the importance of this effect to find under which conditions it can leave a signature in the small-size end of a disc's particle size distribution (PSD). An important part of this work is to map out, in a disc at steady-state, what is the most likely collisional origin for micron-sized grains, in terms of the sizes of their collisional progenitors. We implement, for the first time, the surface energy constraint into a collisional evolution code. We consider a debris disc extending from 50 to 100AU and 2 different stellar types. We also consider two levels of stirring in the disc: dynamically "hot" (e=0.075) and "cold" (e=0.01)...

    International Nuclear Information System (INIS)

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG)

  3. Radiation Treatment of Meat Products and Animal By-Products

    International Nuclear Information System (INIS)

    Application of radiation in food technology can only be considered as an alternative to existing preservation methods when a higher quality product and/or a cheaper product will result, or in cases where no alternative methods exist. With this view in mind, work performed at the Danish Meat Research Institute on sliced bacon, canned hams, luncheon meat, and animal feeding stuffs, i.e. meat and bone meal and blood meal, is reviewed and discussed. The conclusion drawn from the experimental results is that the formation of off-flavours in irradiated meat products is a very serious problem and the most important obstacle to a successful application of irradiation in meat processing. It is, therefore, essential that future research should concentrate on finding means to reduce the irradiation flavour. A number of approaches to solve this problem are mentioned and the Danish work in this field which has been centred mainly on the use of very high dose-rates and of non-equal dose distribution in cans is reviewed, and the concepts briefly described.

  20. Phototrophic pigment production with microalgae: biological constraints and opportunities.

    Mulders, Kim J M; Lamers, Packo P; Martens, Dirk E; Wijffels, René H

    2014-04-01

    There is increasing interest in naturally produced colorants, and microalgae represent a bio-technologically interesting source due to their wide range of colored pigments, including chlorophylls (green), carotenoids (red, orange and yellow), and phycobiliproteins (red and blue). However, the concentration of these pigments, under optimal growth conditions, is often too low to make microalgal-based pigment production economically feasible. In some Chlorophyta (green algae), specific process conditions such as oversaturating light intensities or a high salt concentration induce the overproduction of secondary carotenoids (β-carotene in Dunaliella salina (Dunal) Teodoresco and astaxanthin in Haematococcus pluvialis (Flotow)). Overproduction of all other pigments (including lutein, fucoxanthin, and phycocyanin) requires modification in gene expression or enzyme activity, most likely combined with the creation of storage space outside of the photosystems. The success of such modification strategies depends on an adequate understanding of the metabolic pathways and the functional roles of all the pigments involved. In this review, the distribution of commercially interesting pigments across the most common microalgal groups, the roles of these pigments in vivo and their biosynthesis routes are reviewed, and constraints and opportunities for overproduction of both primary and secondary pigments are presented.

    Harnessing the metabolic potential of photosynthetic microbes for next-generation biotechnology objectives requires detailed scientific understanding of the physiological constraints and regulatory controls affecting carbon partitioning between biomass, metabolite storage pools, and bioproduct synthesis. We dissected the cellular mechanisms underlying the remarkable physiological robustness of the euryhaline unicellular cyanobacterium Synechococcus sp. strain PCC 7002 (Synechococcus 7002) and identify key mechanisms that allow cyanobacteria to achieve unprecedented photoautotrophic productivities (~2.5-h doubling time). Ultrafast growth of Synechococcus 7002 was supported by high rates of photosynthetic electron transfer and linked to significantly elevated transcription of precursor biosynthesis and protein translation machinery. Notably, no growth or photosynthesis inhibition signatures were observed under any of the tested experimental conditions. Finally, the ultrafast growth in Synechococcus 7002 was also linked to a 300% expansion of average cell volume. We hypothesize that this cellular adaptation is required at high irradiances to support higher cell division rates and reduce deleterious effects, corresponding to high light, through increased carbon and reductant sequestration.

    2008-07-01

    Full Text Available Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water supply and air quality. Although the role of these forages for animal production could vary depending upon the regional preferences for the animal and forage species, climate and resources, their importance in the success of ruminant production is acknowledged. However with the increasing global human population and urbanisation, the sustainability of forage based animal production systems is sometimes questioned due to the interrelationship between animal production and the environment. It is therefore vital to examine the suitability of these systems for their place in the future to supply quality food which is safe for human consumption and available at a competitive price to the growing human population. Grassland and forage crops are recognised for their contribution to the environment, recreation and efficiency of meat and milk production,. To maintain sustainability, it is crucial that such farming systems remain profitable and environmentally friendly while producing nutritious foods of high economical value. Thus, it is pertinent to improve the nutritive value of grasses and other forage plants in order to enhance animal production to obtain quality food. It is also vital to develop new forages which are efficiently utilised and wasted less by involving efficient animals. A combination of forage legumes, fresh or conserved grasses, crop residues and other feeds could help develop an animal production system which is economically efficient, beneficial and viable. Also, it is crucial to use efficient animals, improved forage conservation methods, better manure handling, and minimum

    As part of our regular Coordinated Research Project (CRP) activities and our technical support given to ongoing national and regional Technical Cooperation projects (TCPs), the Section evaluated our activities as part of the Agency's 2004/2005 midterm performance evaluation. During this exercise we could identify areas where good performances were achieved as well as those where further improvements were needed and which we then addressed. It became apparent that more proactive measures are needed towards the detection, control and management of emerging diseases, with particular emphasis on transboundary animal diseases and the offering of relevant support to Member States. A particular case in point is the current avian influenza situation. This issue discussed the problem posed by rinderpest and the Agency's effort in eradicating this viral disease

    The present study is an attempt to assess the situation of feed industries and the quality of feed in Nepal. Feed production is a major component of poultry industry, because near about 80% of total cost require for production goes to feed. There are altogether 149 feed industries of different size in different location in operation. About 45% of them are of small unit producing less than 5 tones/day. About 35% are of medium size producing 6-10 tones/day, and rest 20% is of large size produci...

    International Nuclear Information System (INIS)

    In the June 2004 Newsletter, we focused on the topic of molecular diagnostic technologies and the way forward. It is clear from the feedback, that there is a strong desire for having reliable, definitive, sensitive, specific, cost effective and on-site diagnostic tests, in parallel with so-called herd or population surveillance tests. This will allow for the implementation of more effective disease control strategies. It is indeed exciting to consider the current technological explosion and its consequences and what potential advantages might be in store for many of our Member States. This will also help to ensure that we keep abreast of new developments and employ the most appropriate tools.The conclusions and recommendations will be placed on the web as soon as they are available and published in the next Newsletter. The second topic under discussion in this Newsletter will focus on the management of animal genetic resources. Both past and future activities are described in further detail in this issue

  13. BIOGAS PRODUCTION FROM WASTE TO ANIMAL

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Climate change is a current issue. Greenhouse gas emissions (GGEs are changing the atmosphere physio-chemical characteristics also affecting biosphere natural balance and life quality on Earth. The search for renewable and clean source is an alternative to reverse, control and attenuate the problems caused by greenhouse gases. Biomass is one of the major energy sources available in rural and agribusiness areas. Anaerobic biological degradation of organic material present in solid agricultural waste generates a gaseous mixture of methane (CH4 and carbon dioxide (CO2, called biogas. It is possible to use its energy potential through the burning and obtaining of thermal energy. Biogas generation offers producers a renewable energy source of optimum performance which supports external electric expenses and provides clean energy as well as adequate distribution of generated effluent. Biogas usage is a large energetic potential concerning small and medium-sized farms. This paper aims at observing how this kind of energy can help the control of GGE emissions, adequate animal waste disposal as well dumping and especially the generation of clean and renewable energy. It also intends to answer questions about this technology aiming to help producers to take advantages of such technique by decreasing electric energy costs providing an economical development as well as improvement on local and national energetic area.

  16. Improvement of animal production through research using radioisotopes and radiation

    International Nuclear Information System (INIS)

    High birth rates coupled with greater longevity continue to increase the.world's population, especially in the less developed countries. The prevention of undernutrition and ultimately starvation will only be averted by increased food production and more efficient use of that food. At the same time people who have largely subsisted upon plant food diets and whose standards of living are rising, want to increase the use of animal products in order to upgrade their diets. To provide this high quality food animal scientists must find ways of increasing the supply especially in the less developed countries. Since most of the available pasture lands are presently being fully utilized or overgrazed, improved efficiency of the present herds and use of agroindustrial wastes are the only methods left to increase production significantly. The use of radioisotopes and radiation in research are making major contributions to the understanding of the processes necessary to achieve better animal production. In order to provide a forum for exchange of information in this field, the FAO/IAEA Joint Division of Atomic Energy in Food and Agriculture organized an international symposium, held in Vienna, from 2?6 February, on the use of nuclear techniques in animal production. Among the topics discussed at the symposium were: Soil-plant-animal relations regarding minerals, Trace elements in animal nutrition, Calcium, phosphorus and magnesium metabolism, Protein (nitrogen) metabolism - ruminants Protein (nitrogen) metabolism - non-ruminants Nuclear techniques in the control of parasitic infections Animal endocrinology with special emphasis on radioimmunoassays

  1. Study on Romanian Consumers’ Opinion Regarding the Animal Welfare Labelling of Animal Products

    Directory of Open Access Journals (Sweden)

    Ludovic Toma Cziszter

    2010-10-01

    Full Text Available The aim of the paper was to investigate the influence some factors on the consumers’ opinion regarding the animal welfare labelling of animal products. The analysed question was: “When purchasing eggs, meat or milk can you easily identify from the label those products sourced from animal welfare friendly production systems?” Respondents chosen only one answer out of the five offered: yes, most of the time; yes, some of the time; no, very rarely; no, never; and don’t know. Thirty three percent of females considered they could find sometime information regarding the animal welfare on the labels, while males considered that this information could be found very rarely. Up to 55 years of age, 50% of the consumers consider that the labels do not contain the information about animal welfare, while after this age most of consumers consider they found this information on the labels. Over 50% of Orthodox and Roman Catholic responders considered that the information on animal welfare on the labels was found some of the time or very rarely. Respondents, irrespective of their living area or monthly income, considered that there is scarce information regarding animal welfare on the labels. Internet access significantly influenced the consumers regarding the availability of the information on the labels.

  2. Transfer of radionuclides to animal products following ingestion or inhalation

    International Nuclear Information System (INIS)

    Contamination of animal products forms an important pathway in the transfer of radionuclides from source to man. Simulation of radionuclide transfer via animal products requires an understanding of the processes and mechanisms involved in absorption, distribution, turnover and excretion of radionuclides and related elements in animals as well as knowledge of animal grazing habits and husbandry. This paper provides a summary of the metabolism of important radionuclides in typical domestic animals and of the mathematical approaches that have been used to simulate transfer from diet to animal product. The equilibrium transfer factor approach has been used widely but suffers a number of disadvantages when releases or intakes are variable with time or when intakes are short relative to the lifetime of the animal of interest. Dynamic models, especially those of the compartmental type, have been developed and used widely. Both approaches have benefited from experiences obtained after the Chernobyl accident but a number of uncertainties still exist. Whereas there is now extensive knowledge on the behaviour of radiocaesium in both domestic and wild animals, knowledge of the behaviour of other potentially important radionuclides remains limited. Further experimental and metabolic studies will be required to reduce uncertainties associated with the transfer of radionuclides other than radiocaesium and thereby produce a sound basis for radiological assessments.

  3. Preclinical safety testing for cell-based products using animals.

    Science.gov (United States)

    McBlane, James W

    2015-09-01

    The objectives of preclinical testing include to show why there might be therapeutic benefit in patients and to provide information on the product's toxicity. For cell-based products, given even once, there may be long term exposure and this could imply, unlike for conventional drugs, that all preclinical studies may be needed prior to first human use. The duration of exposure to cells should be studied in animals to guide toxicity assessments. Distribution of cells after administration by a route resembling that intended in humans should be studied to understand potential risks. Risk of tumour formation with the product may also need to be characterised. To the extent that this information can be generated by in vitro testing, studies in animals may not be needed and limitations on the capability of preclinical data to predict human toxicity are recognised: species-specificity make some cell products act only in humans and a human cell-product might be expected to be rejected by immunocompetent animals. Does this suggest testing in immunosuppressed animals or of development of an animal-cell product supposedly similar to the human cell product? No single answer seems to fit every situation.

  4. Animal Production and Health Newsletter, No. 60, July 2014

    International Nuclear Information System (INIS)

    This year, the Animal Production and Health Section is 50 years old. The Animal Production and Health Section identifies new areas of interest based on the Member States' needs to improve efficiencies and to control threats to animal production and health. To this effect, several platforms, assays, diagnostic kits and technical procedures have been developed, adapted and transferred to Member States, supported by R&D, expert technical backstopping and guidance from our Animal Production and Health Laboratory. In addition, several nuclear based technologies (such as reproduction and disease related technologies (such as reproduction and disease related radioimmunoassay have been adapted to other types of chemistries (e.g. chemiluminescence instead of isotopes) to be used at the farm level. Stable isotopes and radioisotopes, however, still play an important and niche role to achieve the levels of sensitivity and specificity needed by the livestock community in ensuring secure and safe food, to follow and measure feed and nutritional conversion into usable energy in the animal, to improve animal breeding traits towards more and of better quality animals, to monitor migratory animals and their associated pathogens, to generate safe and protective animal vaccines through the irradiation of pathogens and to develop and transfer early and rapid diagnostic platforms. Looking back at the activities of the past six months, we had several workshops, training courses, research co-ordination meetings (RCMs) and consultants meetings. Activities scheduled for the next half-year include project review meetings, RCMs, inter-regional training courses and regional workshops. Both past and future activities are discussed in further detail in this newsletter and are also further accessible at our website

  6. Nutritional Value of Irradiated Animal Feed By-Products

    International Nuclear Information System (INIS)

    Animal feed by-products, widely used in animal diets, are sources of disease organisms for animals and for human beings. Salmonella is the principal genus of concern.Radiation treatment (radicidation, radurization) is a promising method of decontamination of feed ingredients. Commercial samples of fish, meat, and blood meals were sealed by heat in polyethylene bags and irradiated at dose levels of 5.0, 10, 20 and 50 kGy. Their chemical analysis were carried out according to A. O. A.C [1] and the total protein efficiency (TPE) of the three animal feed by-products was determined according to Wood ham (2) by using one day old Dokki-4 chicks. Radiation induced an insignificant effect on the chemical constituent of meals. Also, the same trend was observed with TPE of both fish and meat meals. However, irradiation treatments improved TPE values of irradiated blood meal samples. From the results, it could be concluded that irradiation of animal feed by-products up to a dose level of 50 Gy has no adverse effects on the nutritional value of animal feed by-products

  7. Managing Demand and Sales Dynamics in New Product Diffusion Under Supply Constraint

    OpenAIRE

    Teck-Hua Ho; Sergei Savin; Christian Terwiesch

    2002-01-01

    The Bass diffusion model is a well-known parametric approach to estimating new product demand trajectory over time. This paper generalizes the Bass model by allowing for a supply constraint. In the presence of a supply constraint, potential customers who are not able to obtain the new product join the waiting queue, generating backorders and potentially reversing their adoption decision, resulting in lost sales. Consequently, they do not generate the positive "word-of-mouth" that is typically...

  8. Prospects from agroecology and industrial ecology for animal production in the 21st century.

    Science.gov (United States)

    Dumont, B; Fortun-Lamothe, L; Jouven, M; Thomas, M; Tichit, M

    2013-06-01

    Agroecology and industrial ecology can be viewed as complementary means for reducing the environmental footprint of animal farming systems: agroecology mainly by stimulating natural processes to reduce inputs, and industrial ecology by closing system loops, thereby reducing demand for raw materials, lowering pollution and saving on waste treatment. Surprisingly, animal farming systems have so far been ignored in most agroecological thinking. On the basis of a study by Altieri, who identified the key ecological processes to be optimized, we propose five principles for the design of sustainable animal production systems: (i) adopting management practices aiming to improve animal health, (ii) decreasing the inputs needed for production, (iii) decreasing pollution by optimizing the metabolic functioning of farming systems, (iv) enhancing diversity within animal production systems to strengthen their resilience and (v) preserving biological diversity in agroecosystems by adapting management practices. We then discuss how these different principles combine to generate environmental, social and economic performance in six animal production systems (ruminants, pigs, rabbits and aquaculture) covering a long gradient of intensification. The two principles concerning economy of inputs and reduction of pollution emerged in nearly all the case studies, a finding that can be explained by the economic and regulatory constraints affecting animal production. Integrated management of animal health was seldom mobilized, as alternatives to chemical drugs have only recently been investigated, and the results are not yet transferable to farming practices. A number of ecological functions and ecosystem services (recycling of nutrients, forage yield, pollination, resistance to weed invasion, etc.) are closely linked to biodiversity, and their persistence depends largely on maintaining biological diversity in agroecosystems. We conclude that the development of such ecology

  9. Nuclear and related techniques in animal production and health

    International Nuclear Information System (INIS)

    The international symposium was attended by about 130 participants from 45 countries and included 83 scientific presentations of which 42 were posters. This volume covers four principal and interrelated topics: adaptation of animals to the environment, and animal reproduction, health and nutrition. Within each topic, consideration is given to those nuclear and related techniques currently employed in investigative research and their usefulness in studying animal production systems. Progress towards new areas of application and new techniques is also covered, particularly the development and practicability of immunoassay and related biotechnological methods for the diagnosis of livestock diseases. A separate abstract was prepared for each of the papers in this volume

    Infrared thermography is a working technology for over decades, which have been applied mainly in the buildings. We want to move this use to the animal production in order to help us to detect problems of energy efficiency in the facilities preventing, for example, the animal's welfare. In animal production it is necessary to provide a suitable microclimate according to age and production stage of the animals. This microclimate is achieved in the facilities through the environment modification artificially, providing an appropriate comfort for the animals. Many of the problems detected in farms are related to a poor environmental management and control. This is where infrared thermography becomes an essential diagnostic tool to detect failures in the facilities that will be related with health and performance of the animals. The use of this technology in energy audits for buildings, facilities, etc. is becoming more frequent, enabling the technician to easily detect and assess the temperature and energy losses, and it can be used as a support to draft reports and to transmit the situation to the owner in a visual format. In this way, both will be able to decide what improvements are required. Until now, there was not an appropriate technology with affordable prices and easy to manage enough in order to allow the use of the thermography like a routine tool for the diagnostic of these problems, but currently there are some solutions which are starting to appear on the market to meet the requirements needed by the industry.

    -increase target of 2° might imply a severe constraint on the long-term global consumption of animal food. Due to the relatively limited potential for reducing food-related emissions by higher productivity and technological means, structural changes in food consumption towards less emission-intensive food might be required for meeting the 2° target.

  12. Animal production and health newsletter. No. 46, July 2007

    International Nuclear Information System (INIS)

    In response to many requests from our readers, I will continue to highlight a practical topic related to animal production and health in this section of the newsletter. Increasing the efficiency of animal reproduction is a critical component of a holistic approach to sustainably increase animal productivity in developing Member States. For example, the resources spent to formulate and obtain the ingredients for dairy rations are wasted when a significant proportion of the cows in the herd are dry due to delays in achieving pregnancy. Effective genetic selection to improve productivity is only possible if a regular supply of potential replacements is generated by the females already in the herd or flock. For this reason, improving reproductive efficiency is a key aspect of many of the APH projects

  13. A mathematical formulation for interface-based modular product design with geometric and weight constraints

    Science.gov (United States)

    Jung-Woon Yoo, John

    2016-06-01

    Since customer preferences change rapidly, there is a need for design processes with shorter product development cycles. Modularization plays a key role in achieving mass customization, which is crucial in today's competitive global market environments. Standardized interfaces among modularized parts have facilitated computational product design. To incorporate product size and weight constraints during computational design procedures, a mixed integer programming formulation is presented in this article. Product size and weight are two of the most important design parameters, as evidenced by recent smart-phone products. This article focuses on the integration of geometric, weight and interface constraints into the proposed mathematical formulation. The formulation generates the optimal selection of components for a target product, which satisfies geometric, weight and interface constraints. The formulation is verified through a case study and experiments are performed to demonstrate the performance of the formulation.

  14. Animal production and health newsletter, No. 50, July 2009

    International Nuclear Information System (INIS)

    The biggest event this year was undoubtedly, the successful International Symposium on Sustainable Improvement of Animal Production and Health that was held from 8 to 11 June 2009, here in Vienna. It was attended by more than 400 participants from about 100 Member States of the IAEA and FAO, including several international organizations, with oral and poster contributions. The most important aspects of the symposium were to renew old and form new acquaintances, to discuss common topics and strategies and to form networks and partnerships to address animal production and health problems. The symposium was indeed topical and designed to address issues of importance to our Member States. The new and emerging areas of interest such as One Heath, Food Security and Safety and our ability to produce more and healthier animals and animal products in an 'environmentally safe, clean and ethical' way were hotly discussed. Some of the conclusions and challenges that animal scientists face, whose primary concern have been improving livestock productivity, are more extensively reported on in this newsletter. In addition, we will publish full length papers of all the oral presentations, and some of the most imminent poster presentations, as symposium proceedings shortly. Both past and future activities are described in further detail in this newsletter

  15. New phonotactic constraints learned implicitly by producing syllable strings generalize to the production of new syllables.

    Science.gov (United States)

    Warker, Jill A; Dell, Gary S

    2015-11-01

    Novel phonotactic constraints can be acquired by hearing or speaking syllables that follow a novel constraint. When learned from hearing syllables, these newly learned constraints generalize to syllables that were not experienced during training. However, generalization of phonotactic learning to novel syllables has never been persuasively demonstrated in production. The typical production experiment examines phonotactic learning through speech errors. After participants repeat syllable sequences embedded with a novel phonotactic constraint, such as /f/ appearing only in onset position, their speech errors come to adhere to the novel constraint. For example, when participants mistakenly move an /f/ to another syllable, it overwhelmingly moves to an onset rather than a coda position. We assessed whether constraints learned and measured in this manner generalize to unexperienced syllables and, at the same time, whether the slips tend to create previously experienced syllables (a syllable priming effect). We found evidence of generalization but not of syllable priming in participants' speech errors. The effect of phonotactic learning was as powerfully expressed during the production of unexperienced as experienced syllables. A connectionist model simulated the experimental results using a single learning mechanism and successfully reproduced the constraint learning, generalization, and lack of priming.

  16. On-site Labour Productivity of New Zealand Construction Industry: Key Constraints and Improvement Measures

    Directory of Open Access Journals (Sweden)

    Serdar Durdyev

    2011-09-01

    Full Text Available Productivity is key to the survival and growth of any organisation, industry or nation. Some factors constrain the achievement of the set project objectives in the New Zealand building and construction industry and are responsible for the reported steady decline of productivity and performance. This study aims to identify the key constraints to on-site labour productivity and improvement measures. Using the descriptive survey method, views of some project managers, contractors and subcontractors in New Zealand were canvassed via pilot interviews and questionnaire surveys at the qualitative and quantity data gathering stages, respectively. Multi-attribute technique was used to analyse the quantitative data. Results showed that the key external constraints to on-site labour productivity comprise, in order of decreasing impact, statutory compliance, unforeseen events and wider external dynamics. The internal constraints, which contribute 67 percent of the onsite productivity issues, comprise reworks, level of skill and experience of the workforce, adequacy of method of construction, buildability issues, and inadequate supervision and coordination. . The factors underlying each broad category of external and internal constraints are reported. The relative levels of impact of the identified constraints are expected to guide the project team in addressing the constraints in a cost-effective manner.

    Science.gov (United States)

    Hartung, J

    1995-07-01

    Animal agriculture is increasingly regarded as a source of pollutants such as gases, odours and particulates which may be both aggravating and ecologically harmful. An overview of the origin, number and quantity of pollutants emitted from animal housing and from manure stores is presented and possible means of preventing or reducing them are discussed. Of the 136 trace gases in the air of animal houses ammonia (NH3), methane (CH4) and nitrous oxide (N2O) present the greatest risk to the environment. The gases and particulates are emitted principally from freshly deposited and stored excreta, from animal feed, from litter and from the animals themselves. Total NH3 emissions from animal production in Germany are estimated as approximately 750,000 t/a. It is calculated that the average of which is higher than the average "critical loads" for most natural habitats. However, there is still a shortage of satisfactory information on the extent of emissions, in particular on those from naturally ventilated animal houses. NH3 has a direct effect on the trees in the vicinity of animal houses and is also transported long distances through the air contributing to eutrophication and acidification of water and soil. This frequently results in changes in plant ecology, hence reducing plant diversity. CH4 and N2O contribute to the "greenhouse effect". Emissions of CH4 from animal husbandry in Germany are estimated at about 1.5 Mt/a. This corresponds to 0.2% of the assumed global emission from all sources. There is still little knowledge about the quantities of N2O released from agricultural animals. The concentration of airborne microorganisms in livestock housing is between some 100 and several 1000 per liter of air.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8591757

    Science.gov (United States)

    Farouk, M M; Pufpaff, K M; Amir, M

    2016-10-01

    Islam teaches zero-tolerance to all forms of animal abuse throughout the halal meat production supply chain and demands that when animals are slaughtered, they must be slaughtered in the mindful and attentive way espoused by the Prophet Muhammad. Why then are poor practices and animal welfare abuses still occurring during halal meat production, and how can they be reduced or eliminated? In this review we discuss how improvements might be achieved through: (1) training of staff regarding the religious and regulatory requirements of animal welfare from on-farm to slaughter; (2) empathy and compassion assessment of applicants prior to employment; (3) installation of CCTV cameras around lairage and slaughter sites; (4) regular employee follow-up training to minimise 'compassion fatigue'; (5) incorporating animal welfare requirements in halal certification; (6) using mosque-based sermons by Imams to increase awareness of animal welfare issues; and (7) making portable humane slaughter units available to small cottage operations and home/neighbourhood-kills through mosque-based organizations/structures.

    2016-03-01

    Candy products are consumed all across the world, but there is not much information about their composition. In this study we have used a DNA-based approach for determining the animal species occurring in 40 commercial candies of different types. We extracted DNA and performed PCR amplification, cloning and sequencing for obtaining species-informative DNA sequences. Eight species were identified including fish (hake and anchovy) in 22% of the products analyzed. Bovine and porcine were the most abundant appearing in 27 samples each one. Most products contained a mixture of species. Marshmallows (7), jelly-types, and gummies (20) contained a significantly higher number of species than hard candies (9). We demonstrated the presence of DNA animal species in candy product which allow consumers to make choices and prevent allergic reaction.

  6. Management to reduce nitrogen losses in animal production.

    Science.gov (United States)

    Rotz, C A

    2004-01-01

    Reduction of nitrogen loss in animal production requires whole-farm management. Reduced loss from one farm component is easily negated in another if all components are not equally well managed. Animal excretion of manure N can be decreased by improving the balance of protein or amino acids fed to that required by individual animals or animal groups or by improving production efficiency. Management to increase milk, meat, or egg production normally improves efficiency by reducing the maintenance protein required per unit of production. Large losses of manure nitrogen occur through the ammonia and nitrous oxide that are emitted into the atmosphere and the nitrate leached into groundwater. Up to half of the excreted nitrogen is lost from the housing facility, but this loss can be decreased through frequent manure removal and by avoiding deep litter systems and feedlots. Techniques such as acid treatment of manure, scrubbing of ventilation air, and floor designs for separating feces and urine substantially reduce ammonia emissions, but these practices are often impractical or uneconomical for general use. Manure storage units improve nutrient utilization by allowing better timing of nutrient application with crop needs. At least 70% of the nitrogen entering anaerobic lagoons is typically lost, but a less than 10% loss can be maintained using slurry storage with a natural crust or other cover, or by drying poultry manure to at least 50% dry matter. Irrigation and surface spreading of manure without soil incorporation often ensures the loss of all remaining nonorganic nitrogen (typically, 20 to 40% of remaining nitrogen). Rapid incorporation and shallow injection methods decrease this loss by at least 50%, and deep injection into the soil essentially eliminates this loss. For grazing animals, excessive loss can be avoided by not overstocking pastures and avoiding late fall and winter grazing. Reducing emissions between the animal and the soil can lead to greater leaching

  7. Nuclear techniques in animal production and health and food irradiation

    International Nuclear Information System (INIS)

    Nuclear techniques applied to animal production and health are concentrated in three main fields: Animal nutrition, reproduction and animal health. Isotopic markers, both radioactive (''1''4C, ''51Cr, 32P and 35S) and stable (15N), have been used in the development of feeding strategies by understanding the rumen fermentation process, and how protein and other nutrients are utilized to determine a balanced diet for meeting animal requirements for growth, pregnancy and lactation. The simple and easily applicable technology was developed for the preparation of a urea mineral multi nutrient block as a supplement and animal cake for the replacement of concentrate feed used by dairy cattle holders. The model was developed in Yerli Kara Cattle and its cross-breeds to estimate protein requirements of animals. Progesterone immunoassays (RIA/EIA) make it possible to control the reproductive performance of cattle, sheep and goats. A milk progesterone enzyme immunoassay kit known as Reprokon was developed at our Center. The kit has licensed by the Ministry of Agriculture and Rural Affairs. As for animal diseases, especially parasitic infections, nuclear techniques have proved to be of great value, namely in the production of irradiated vaccines against helminitic diseases. The Enzyme Linked Immunosorbent assay (ELISA) diagnostic techniques were used on the diagnosis of babesiosis, a disease which cause great economic loss in livestock in Turkey. Food irradiation is the treatment of raw, semi-processed or processed food or food ingredients with ionizing radiation to achieve a reduction of losses due to insect infestation, germination of root crops, spoilage and deterioration of perishable produce, and/or the control of microorganisms and other organisms that cause food borne diseases

    2014-08-01

    Information on the use and safety of medicines to assist prescription by healthcare professionals occurs in drug labels (Summary of Product Characteristics in Europe and Package Insert in the USA). Animal data (notably genotoxicity, reproduction toxicity and carcinogenicity and/or repeat dose toxicity testing) comprise an important component of the information (having a vital role in giving assurance that an extensive safety assessment for the medicinal product has occurred) and regulatory guidance is available to help inform on its input into drug labels. However, an evaluation of animal data for the 27 new drugs approved in the USA in 2013 (and the same drugs if available in Europe) shows great variability in detail and level of information presented within and across regions and/or the possibility of confusion on interpretation of some of the presented animal study findings. It is concluded that it may be time to revisit what animal data are presented in drug product labels (although bearing in mind current regional regulatory guidance requirements), not only to allow within and across region consistency on information given but to present it in a way that fully assists healthcare professions when prescribing a medicine.

    Abbas, B; Yousif, M A; Nur, H M

    2014-12-01

    The Horn of Africa (Djibouti, Ethiopia, Somalia, Eritrea) is home to the largest population of livestock in Africa and is the historic centre of the livestock trade to the Middle East and northern Africa. The recent resumption of livestock exports from the region has resulted in the handling of over one million head of cattle, sheep, goats and camels at one quarantine facility during a single year. Several of the importing countries for which the facility operates have differing hygiene requirements for the same diseases. Most of the animals handled in the facility come from pastoralist areas, which lack state Veterinary Services. The pathological conditions encountered during one year of monitoring were recorded and the impacts of some of the endemic diseases are discussed, together with particular import-limiting hygiene requirements on this trade.

  12. Uses of radioactive and stable isotopes in animal production research

    International Nuclear Information System (INIS)

    Since the fifties, the widespread use of radioactive isotopes and radiation in the metabolic and clinical studies began. Fully coverage of uses of radioactive isotopes and radiation in research on animal health and animal production is a tedious process. This requires a classification of the manifold applications of radioisotopes which is a quantitative classification provides the necessary information about the quantities of the labelled compound or element or corresponding stable compound during metabolic processes. The second classification of applications is a qualitative classification that identifies the location of the labelling or compound. These qualitative and quantitative applications are divided into two types: fixed applications, which include measurements at a specific time, and changing applications, which include the rate of change over time. The aim of this study is to cover the applications of radioactive isotopes in animal studies, and indicate how to benefit from the results of studies of radioactive isotope quantity and its corresponding stable isotope using methods of comparison or mitigation.

  13. Uncertainty management by relaxation of conflicting constraints in production process scheduling

    Science.gov (United States)

    Dorn, Juergen; Slany, Wolfgang; Stary, Christian

    1992-01-01

    Mathematical-analytical methods as used in Operations Research approaches are often insufficient for scheduling problems. This is due to three reasons: the combinatorial complexity of the search space, conflicting objectives for production optimization, and the uncertainty in the production process. Knowledge-based techniques, especially approximate reasoning and constraint relaxation, are promising ways to overcome these problems. A case study from an industrial CIM environment, namely high-grade steel production, is presented to demonstrate how knowledge-based scheduling with the desired capabilities could work. By using fuzzy set theory, the applied knowledge representation technique covers the uncertainty inherent in the problem domain. Based on this knowledge representation, a classification of jobs according to their importance is defined which is then used for the straightforward generation of a schedule. A control strategy which comprises organizational, spatial, temporal, and chemical constraints is introduced. The strategy supports the dynamic relaxation of conflicting constraints in order to improve tentative schedules.

  15. OBSERVATIONAL CONSTRAINTS ON METHANOL PRODUCTION IN INTERSTELLAR AND PREPLANETARY ICES

    International Nuclear Information System (INIS)

    Methanol (CH3OH) is thought to be an important link in the chain of chemical evolution that leads from simple diatomic interstellar molecules to complex organic species in protoplanetary disks that may be delivered to the surfaces of Earthlike planets. Previous research has shown that CH3OH forms in the interstellar medium predominantly on the surfaces of dust grains. To enhance our understanding of the conditions that lead to its efficient production, we assemble a homogenized catalog of published detections and limiting values in interstellar and preplanetary ices for both CH3OH and the other commonly observed C- and O-bearing species, H2O, CO, and CO2. We use this catalog to investigate the abundance of ice-phase CH3OH in environments ranging from dense molecular clouds to circumstellar envelopes around newly born stars of low and high mass. Results show that CH3OH production arises during the CO freezeout phase of ice-mantle growth in the clouds, after an ice layer rich in H2O and CO2 is already in place on the dust, in agreement with current astrochemical models. The abundance of solid-phase CH3OH in this environment is sufficient to account for observed gas-phase abundances when the ices are subsequently desorbed in the vicinity of embedded stars. CH3OH concentrations in the ices toward embedded stars show order-of-magnitude object-to-object variations, even in a sample restricted to stars of low mass associated with ices lacking evidence of thermal processing. We hypothesize that the efficiency of CH3OH production in dense cores and protostellar envelopes is mediated by the degree of prior CO depletion.

  16. Constraints on the proton's gluon distribution from prompt photon production

    International Nuclear Information System (INIS)

    We analyze the capability of prompt photon production in pp and p anti p collisions to constrain the gluon distribution of the proton, considering data from fixed-target experiments as well as collider measurements. Combined fits are performed to these large-pT direct-γ cross sections and lepton-proton deep-inelastic scattering data in the framework of next-to-leading order perturbative QCD. Special attention is paid to theoretical uncertainties originating from the scale dependence of the results and from the fragmentation contribution to the prompt photon cross section. (orig.)

    The first six months of this year have been a busy time for all personnel in the sub-programme. Apart from our regular Co-ordinated Research Project (CRP) activities and our technical support given to on-going national and regional Technical Co-operation (TC) projects, we were also involved in the initiation (together with TC country officers) of the 2014/15 biennial TC project cycle. In addition to this, when carrying out our 2010/11 end of cycle programmatic performance evaluations, we could identify the areas where good performance was achieved as well as areas where further improvements are needed. It is hoped that our inputs will serve the best interests of our Member States for the present programme cycle 2012-2013. In response to many requests from our readers, I have decided to give a brief overview of our Subprogramme as background to the upcoming 'Scientific Forum' (Food for the Future: Meeting the Challenges with Nuclear Applications) that will take place during he IAEA General Conference in September 2012. The focus of the Animal production and Health Subprogramme activities is on enhancing food security by supporting sustainable livestock production systems in developing countries. This is to be achieved by strategic and applied research, technology transfer and capacity building. The three principal components of the sub-programme are animal nutrition, animal reproduction and breeding and animal health. Problems are identified and solutions developed through the use of strategically applied nuclear-based tools, in conjunction with conventional technologies to: - Characterize and optimally utilize locally available feed and feed resources to enhance maximum energy conversion, whilst minimizing methane and CO2 emissions; - Increase animal production through the characterization of livestock genetic make-up to drive the integration of locally adapted animal breeds with trait selected exotic breeds to satisfy the increasing demand for 'more and of better

  1. The transfer of radionuclides into domestic animals and their products

    International Nuclear Information System (INIS)

    The contamination of animal products, especially milk, with radionuclides, are regarded as the important problem in the food chain, and has been one of the remarkable public concerns in Japan since the nuclear tests in 1954. The transfer of several radionuclides into domestic animals and their products is described. 131I, 90Sr and 137Cs are very important as the radionuclides that transfer into domestic animals and their products. The data of the transfer of several orally administered radionuclides into milk from the references are summarized as follows: (1) 131I transfered into milk was 5 -- 30% of dose (cow), 10 -- 40% (goat). (2) 90Sr(89Sr) transfered into milk was 0.6 -- 1.9% (cow), 0.5 -- 0.6% (goat). (3) 137Cs(134Cs) transfered into milk was 10 -- 13% (cow), 7.0% (goat). (4) 140Ba-140La transfered into milk was 0.6% (cow), 0.1 -- 0.2% (goat). (5) 181W transfered into milk was 0.06% (goat). (author)

  2. Optimization based scheduling for a class of production systems with integral constraints

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Operation scheduling for a class of production systems with"instantly consumed"products is very important.It is challenging to satisfy the real time system demand and to consider the realizability of the production schedules.This paper formulates a new model for optimization based production scheduling problems with integral constraints.Based on the detailed analysis of the production rate constraints,it is proved that this type of optimization problems is equivalent to a smooth nonlinear programming problem.The reachable upper and lower bounds of the production amount in every period can be expressed as functions of two variables,i.e.,the production rate at the start and end of that period.It is also proved that the gradients of these functions are monotonic,and their convexity or concavity is guaranteed.When the production cost function is convex,this type of optimization problems is equivalent to a convex programming problem.With the above analysis,a two-stage solution method is developed to solve the production scheduling problems with integral constraints,and in many applications the global optimal solution can be obtained efficiently.With the new model and solution method,the difficulties caused by the constraints on production rate can be overcome and the optimal schedule can be obtained with the real time system demand satisfied.Numerical testing for scheduling of electric power production systems is performed and the testing results are discussed.It is demonstrated that the new model and solution method are effective.

    Full Text Available FPGAs are an attractive platform for applications with high computation demand and low energy consumption requirements. However, design effort for FPGA implementations remains high—often an order of magnitude larger than design effort using high-level languages. Instead of this time-consuming process, high-level synthesis (HLS tools generate hardware implementations from algorithm descriptions in languages such as C/C++ and SystemC. Such tools reduce design effort: high-level descriptions are more compact and less error prone. HLS tools promise hardware development abstracted from software designer knowledge of the implementation platform. In this paper, we present an unbiased study of the performance, usability and productivity of HLS using AutoPilot (a state-of-the-art HLS tool. In particular, we first evaluate AutoPilot using the popular embedded benchmark kernels. Then, to evaluate the suitability of HLS on real-world applications, we perform a case study of stereo matching, an active area of computer vision research that uses techniques also common for image denoising, image retrieval, feature matching, and face recognition. Based on our study, we provide insights on current limitations of mapping general-purpose software to hardware using HLS and some future directions for HLS tool development. We also offer several guidelines for hardware-friendly software design. For popular embedded benchmark kernels, the designs produced by HLS achieve 4X to 126X speedup over the software version. The stereo matching algorithms achieve between 3.5X and 67.9X speedup over software (but still less than manual RTL design with a fivefold reduction in design effort versus manual RTL design.

    Transgenic animals are used in industry and in biomedical research in order to provide in vivo experimental model systems. Sperm cells have been reported used as vectors in the production of transgenic animals before, however no approach has of yet proven to be successful. Fertilizing eggs with genetically modified sperm would be advantageous in that sperm are readily accessible and stable, and eggs can be fertilized by modified sperm cells in vivo. Recent elucidations regarding the unique manner of DNA packaging in sperm chromatin by protamines has provided us with the insight for developing a method of introducing foreign DNA into sperm which is likely to succeed where others have failed. We have developed a method for mimicking the in vivo system of sperm chromatin toroid subunits in vitro, concentrating these toroids, and fluorescent visualization. Our present work concerns development of a method to successfully deliver DNA across the cell membranes and into the nucleus.

    Full Text Available We investigate the observational constraints on the inhomogeneous big-bang nucleosynthesis that Matsuura et al. (2005 suggested that states the possibility of the heavy element production beyond 7Li in the early universe. From the observational constraints on light elements of 4He and D, possible regions are found on the plane of the volume fraction of the high-density region against the ratio between high- and low-density regions. In these allowed regions, we have confirmed that the heavy elements beyond Ni can be produced appreciably, where p- and/or r-process elements are produced well simultaneously.

    The 2012 Scientific Forum examined the challenges related to the improvement of food production, food protection and food safety through the use of nuclear applications. In the first session on 'Increasing Food Production' it was noted that the world will need to produce 70% more food between now and 2050 to satisfy the demand of a population in excess of 9 billion people. In this regard, the intensification and diversification of more and higher quality food in a climate-smart and sustainable manner whilst protecting the environment is therefore critical to smallholder farmers and is the key to poverty reduction and increased food security. The Forum noted that the increasing global population faces the challenge of substantially increasing food production under conditions of severe land degradation that has led to a significant reduction in the productive capacity of agricultural lands. Sustainable soil management, plant mutation breeding and animal nutrition and production are therefore critical to the improvement of agricultural productivity. The second session on 'Ensuring Food Protection' noted that global food insecurity is inherently linked to pests and diseases that harm or kill livestock and crops, as well as people working in rural agricultural areas. The losses caused by diseases and pests at both the pre- and post-harvest levels average 30-40% of agricultural outputs, making returns on agricultural investments in land, seeds, water, fertilizer, animal feed, labour and other inputs correspondingly inefficient. In addition, the world is currently facing an unprecedented increase of invasive animal and plant diseases and pests that threaten food security by causing serious losses in production and by necessitating costly control measures, including the escalating use of increasingly expensive pesticides. Outbreaks of secondary pests, the development of resistance of pests to pesticides and the increasing threat of zoonotic diseases to public health cause

  13. Pollution by animal production in The Netherlands: solutions.

    Science.gov (United States)

    Voorburg, J H

    1991-09-01

    Provided that the application rates of manure do not exceed the crop uptake of nutrients, pollution by animal production is mainly caused by nitrogenous substances. Applying manure outside the growing season causes pollution of groundwater and surface water due to leaching and runoff. In regions with a high livestock density, the evaporation of ammonia has a serious impact on the environment. It contributes to acidification and causes a nutrient imbalance in natural vegetation. The prevention of nutrient losses from manure is unprofitable. The environmental impact is not caused by the individual farmer but is a result of the sum of activities in a region. This means that legislation is necessary to impose limits in order to arrive at production without pollution. Within this framework, the farmer should optimise the utilisation of minerals from manure by more efficient animal nutrition and better handling of the manure. One of the most difficult problems is the prevention of ammonia evaporation. A reduction of these losses generally also has a favourable effect on odour emissions. A new development is the processing of manure surpluses into a dried manure of sufficient quality to compete on the fertiliser market. As is usually the case with pollution control, these measures raise the costs of livestock production. PMID:1782422

  14. Interactive sculpting of product shape based on constraint manipulation in virtual environment

    LIU Zhen-yu; TAN Jian-rong

    2005-01-01

    In product concept design, not only designers with professional CAD skills, but also final customers take part in the design and evaluation of product shape styling. Because customers usually lack surface modelling background and are not familiar with concrete operations of commercial CAD systems, it is difficult for them to express their change intentions of product shape through professional CAD tools if they are not satisfied with the current shape design. This paper puts forward a method for creating, dragging and manipulating constraint and load represented in form of icon entity in interactive sculpting of product shape in virtual environment. The method supports customers manipulation of sculpting constraints or loads on sculpting shapes in virtual reality interaction to control the deformation of product shape. Constraints management based on icon entity is similar to spline lofting operation that is familiar to engineers, so users do not need to know surface details or have any professional knowledge of surface modelling, by only using their physical and engineering experience, they can manipulate the sculpting of product shape intuitively.

    Three animal disease issues, amongst others, dominated animal health activities in the world; the near eradication of rinderpest (RP), the continued threat of foot-and-mouth disease (FMD) to national and international trade and the ever spreading avian influenza (AI). The importance of early, rapid and sensitive diagnoses of merging diseases, with special reference to AI, can not be overstated and it has prompted our subprogramme to refocus our activities and efforts. The rapid diagnosis and characterization of AI, particularly with respect to molecular tools, are important to determine whether it is H5N1 or another subtype. It is here that the Joint FAO/IAEA Programme can play a role in supporting the actions of the FAO, World organisation for animal health (OIE), WHO and Member States. The subprogramme can provide technical assistance on (1) which tests and protocols to use, (2) technical and laboratory training, (3) expert missions (nominating relevant expert(s) or to perform expert missions by members of the subprogramme), (4) the analysis of AI samples (as primary diagnosis or as confirmation) utilizing the OIE reference status of our Seibersdorf laboratory (i.e. the analysis of translation products of the virus genome) and (5) the provision of technical quality assurance guidelines and support to ensure quality data and reporting

    In this newsletter, I want to discuss shortly the effects of climate variations, food security and the expansion of animal and zoonotic diseases within the sphere of what the Animal Production and Health Subprogramme can contribute. My take home message would be: • Globalization and climate change are causing an unprecedented worldwide impact on emerging and reemerging animal and zoonotic diseases. • Vector borne diseases are now spreading to previously non-endemic and cooler areas. A dramatically increased incidence in deadly infectious and zoonotic diseases in wildlife, livestock, and people may be the most immediate serious consequence of global warming, food security or food shortage. Globalization and climate change have had a worldwide impact on emerging and re-emerging animal and zoonotic diseases. Climate change is disrupting natural ecosystems by providing more suitable environments for infectious diseases allowing disease-causing bacteria, viruses, and fungi to move into new areas where they may harm wildlife and domestic species, as well as humans. Diseases that were previously limited only to tropical areas are now spreading to other previously cooler areas e.g. Rift Valley fever. Pathogens that were restricted by seasonal weather patterns can invade new areas and find new susceptible species as the climate warms and/or the winters get milder. There is evidence that the increasing occurrence of tropical infectious diseases in the mid latitudes is linked to either global warming or food security. Vector borne diseases are particularly affected by weather patterns and long-term climatic factors strongly influence the incidence of outbreaks. Most of these diseases are caused by insects and their population dynamics are dependent on the prevailing weather conditions, specifically temperature and humidity. Climate change influences local weather conditions and therefore has a significant impact on the presence of vectors and their geographical

  17. Livestock production and manure management on animal farms in Vietnam

    DEFF Research Database (Denmark)

    Sommer, S.G.; Bui, H.H.; Dalsgaard, Anders;

    .  Further, there is little knowledge about the plant nutrient value of animal manure, and about technologies for environmentally-friendly manure management. This lack of knowledge enhances the risk of polluting the environment by inappropriate use of livestock manure and is also a potential risk......  The Vietnamese and Asian livestock production is increasing these years. In consequence large amounts of manure are produced, which may be a hazard to the environment because the traditional technology and the management practise of manure is not adapted to specialised livestock production...... for transferring pathogens between livestock and from livestock to humans (zoonoses). The objective of this article is to describe manure management at livestock farms in Vietnam. The focus is on presenting the most typical farming concepts, manure management on these farms, environmental and hygienic risks...

    International Nuclear Information System (INIS)

    The biggest event in 2011 was the declaration of global freedom from rinderpest by the Food and Agriculture Organization of the United Nations and the World Organisation for Animal Health (OIE). The IAEA celebrated this momentous occasion on the 20th of September 2011, during the IAEA 55th General Conference. The commitment, dedication and hard work of past and present IAEA staff were commended by all participants as the contribution of the IAEA was a critical and essential component of the eradication success. Building on the success of the rinderpest campaign, technology transfer in the field of animal health continued to be a top priority of the Subprogramme during 2011 and this will continue for the future since our next target disease for eradication is peste des petits ruminants (PPR). Member States received support through Technical Cooperation Projects. In most of the tropics, climatic variation, rainfall patterns and droughts reduce plant growth and feed availability and quality leading to extensive livestock losses and reduced productivity. With the assistance of the IAEA, tremendous improvement has been achieved in terms of quantity and quality of the available feed resource base, particularly, in terms of nutritive value, palatability and/or cold and drought tolerance - vital benefits whose effectiveness can be monitored using nuclear technology. Both past and future activities are described in detail in this newsletter and are also accessible at our website (http://www-naweb.iaea.org/nafa/aph/index.html); I thus need not mention them in this section. Please contact us if you have any further ideas, comments, concerns or questions. As discussed in previous newsletters, the Animal Production and Health Subprogramme will continue to move progressively forward and in pace with developments within the livestock field, to optimally serve our Member States.

  1. Energy Supply- Production of Fuel from Agricultural and Animal Waste

    Energy Technology Data Exchange (ETDEWEB)

    2009-03-25

    The Society for Energy and Environmental Research (SEER) was funded in March 2004 by the Department of Energy, under grant DE-FG-36-04GO14268, to produce a study, and oversee construction and implementation, for the thermo-chemical production of fuel from agricultural and animal waste. The grant focuses on the Changing World Technologies (CWT) of West Hempstead, NY, thermal conversion process (TCP), which converts animal residues and industrial food processing biproducts into fuels, and as an additional product, fertilizers. A commercial plant was designed and built by CWT, partially using grant funds, in Carthage, Missouri, to process animal residues from a nearby turkey processing plant. The DOE sponsored program consisted of four tasks. These were: Task 1 Optimization of the CWT Plant in Carthage - This task focused on advancing and optimizing the process plant operated by CWT that converts organic waste to fuel and energy. Task 2 Characterize and Validate Fuels Produced by CWT - This task focused on testing of bio-derived hydrocarbon fuels from the Carthage plant in power generating equipment to determine the regulatory compliance of emissions and overall performance of the fuel. Task 3 Characterize Mixed Waste Streams - This task focused on studies performed at Princeton University to better characterize mixed waste incoming streams from animal and vegetable residues. Task 4 Fundamental Research in Waste Processing Technologies - This task focused on studies performed at the Massachusetts Institute of Technology (MIT) on the chemical reformation reaction of agricultural biomass compounds in a hydrothermal medium. Many of the challenges to optimize, improve and perfect the technology, equipment and processes in order to provide an economically viable means of creating sustainable energy were identified in the DOE Stage Gate Review, whose summary report was issued on July 30, 2004. This summary report appears herein as Appendix 1, and the findings of the report

  2. Grazing management as it affects nutrition, animal production and economics of beef production.

    Science.gov (United States)

    Parsons, S D; Allison, C D

    1991-03-01

    Until recently, the nutritional fate of the grazing animal has been largely ignored by both animal and range scientists despite the economic dependence of the extensive livestock industry on nutrition from grass. Of the three factors that can be manipulated to improve profit gross margin per animal, is one that is directly affected by nutrition and, hence, grazing management. The relationship between economics and grazing management may be summarized as: Gross margin = f(Animal Performance); Animal Performance = f(nutrition); Nutrition = f(grazing). Economical beef production must consider the needs of the animal and the forage plant at the same time. The health of the sward must be maintained while improving individual animal performance and simultaneously increasing stocking rate. Generally, plants that have been defoliated require a period of recovery before again being grazed. A sward is kept in a vigorous state by preventing repetitive defoliation at the one extreme, and avoiding excessive shading (mature growth) of photosynthetic material at the other. This state is best achieved where livestock grazing is controlled. For any individual paddock, periods of grazing are followed by periods that allow adequate physiologic recovery of the plants. A grazing regimen that keeps the plant in a healthy state is fortuitously also well suited to the nutritional requirements of the animal. Animals on overgrazed pastures are likely to suffer from inadequate feed intake because of deficiencies in feed quantity. Conversely, on over-rested pastures, intake deficiency results from paucity in feed quality. On most unmanaged ranges, overgrazed and over-rested plants are likely to be found side by side. By controlling duration of the rest period as well as duration of the grazing period through pasture subdivision, requirements of both the plant and the animal can be met. With artificially high economic demands placed on animal production, some form of supplementation is

    As 2013 draws to a close, we are completing our activities and contributions to the 2012-2013 IAEA and FAO programmes of work and budget, and finalizing our tasks and products and services for the next biennium. We hope that our programme will satisfy Member State needs maximally. I want to mention two events regarding the activities of the Animal Production and Health Subprogramme. First, I have the pleasure to inform you that the Animal Production and Health Subprogramme was part of a 'One-House' IAEA team that was awarded an IAEA Superior Achievement Award for its response to Member States requests regarding the H7N9 avian influenza outbreak in several provinces of China. The aggravating factor with this new avian influenza disease was that it was asymptomatic in poultry (i.e. poultry showed no clinical disease), but symptomatic in humans (i.e. humans showed flu like symptoms) causing about 30% mortality in infected humans. This epidemiological character of the disease made it very difficult to trace and search for its origin in poultry, towards protecting human lives. The Chinese authorities, in particular the Beijing Genetics Institute, reacted appropriately to the outbreaks and characterized the virus, isolated from human patients, as an avian influenza H7N9 subtype. Knowing the panzootic potential of avian influenza viruses, the international community has immediately developed response plans on the eventual spread of the Chinese H7N9 strain and called for emergency preparedness. Upon requests of Member States from Europe and the Asia and Pacific Region, the Animal Production and Health Subprogramme of the Joint FAO/IAEA Division and the IAEA Technical Cooperation Department immediately reacted by taking advantage of the responsiveness of the TC Programme to unforeseen needs of Member States. In addition to the evaluation and validation of diagnostic and surveillance procedures and the transfer of technologies and the diagnostic support, two unplanned

  4. Near infrared spectroscopy in animal science production: principles and applications

    2010-01-01

    Full Text Available Near infrared (NIR is one of the techniques belonging to vibrational spectroscopy. Its radiation (750 to 2500nm interacts with organic matter, and the absorption spectrum is rich in chemical and physical information of organic molecules. In order to extract valuable information on the chemical properties of samples, it is necessary to mathematically process spectral data by chemometric tools. The most important part in the development of an NIR method is building the predicting model generally called calibration. NIR spectroscopy has several advantages over other analytical techniques: rapidity of analysis, no use of chemicals, minimal or no samples preparation, easily applicable in different work environments (on/in/at line applications. On the other hand, NIR spectroscopy has some disadvantages: low ability to predict compounds at low concentration (<0.1%, necessity of accurate analysis as reference, development of calibration models required high trained personnel, need of a large and up-to-date calibration data set (often difficult to obtain, difficulties to transfer calibration among instruments, initial high financial investments. In the feed industry, NIR spectroscopy is used for: feed composition, digestibility (in vivo, in vitro, in situ, traceability assessment (to avoid possible frauds. As far as animal products are concerned, NIR spectroscopy has been used to determine the main composition of meat, milk, fish, cheese, eggs. Furthermore, it was also used to predict some physical properties (tenderness, WHC (Water Holding Capacity, drip loss, colour and pH in meat; coagulation ability in milk; freshness, flavour and other sensorial parameters in cheese. Interesting applications of NIR spectroscopy regard issues like: determination of animal products’ authenticity and the detection of adulteration (in order to prevent frauds, discrimination PDO (Protected Designation of Origin and PGI (Protected Geographical Indication from other non

  7. Impacts of cereal ergot in food animal production

    Directory of Open Access Journals (Sweden)

    Stephanie eCoufal-Majewski

    2016-02-01

    Full Text Available The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the 5th century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which are used as livestock feed. Ergot is found worldwide, with even low concentrations of alkaloids in the diet (<100 ppb total reducing the growth efficiency of livestock. Extended periods of increased moisture and cold during flowering promote the development of ergot in cereal crops. Furthermore, the unpredictability of climate change may have detrimental impacts to important cereal crops such as wheat, barley and rye, favouring ergot production. Allowable limits for ergot in livestock feed are confusing as they may be determined by proportions of ergot bodies or by total levels of alkaloids, measurements which may differ widely in their estimation of toxicity. The proportion of individual alkaloids including ergotamine, ergocristine, ergosine, ergocornine and ergocryptine is extremely variable within ergot bodies and the relative toxicity of these alkaloids has yet to be determined. This raises concerns that current recommendations on safe levels of ergot in feeds may be unreliable. Furthermore, the total ergot alkaloid content is greatly dependent on the geographic region, harvest year, cereal species, variety and genotype. Considerable animal to animal variation in the ability of the liver to detoxify ergot alkaloids also exists and the impacts of factors such as pelleting of feeds or use of binders to reduce bioavailability of alkaloids require study. Accordingly, unknowns greatly outnumber the knowns for cereal ergot and further study to help better define allowable limits for livestock would be welcome.

    Full Text Available Smallholder sugarcane production sector is under researched and underdeveloped with limited industrial link and support. The objectives of this study were to assess the current state of sugarcane production, farmers’ perceived production constraints and preferred traits, and to collect germplasm grown by smallholder farmers in southern Ethiopia for strategic breeding and conservation. The study was conducted across 16 administrative zones, 28 districts and 56 peasant associations involving 560 smallholder sugarcane growers in southern Ethiopia using a participatory rural appraisal (PRA approach. Sugarcane genetic resources were collected through structured sampling. Findings from this study indicated that monocropping was identified as the predominant sugarcane farming system. Respondent farmers prioritized drought tolerance (21%, increased cane yield (20%, early maturity (18%, marketability (17%, and high biomass (14% as the top preferred traits of sugarcane. Ninety diverse sugarcane landraces were collected from homesteads of smallholder farmers. Findings from this study would serve as baseline information towards sugarcane research and development emphasising the constraints and preferences of smallholder sugarcane growers in Ethiopia or similar agro-ecologies. This is the first study to report farmers preferred traits and constraints, and genetic resources of sugarcane under smallholder farming systems in Ethiopia.

    Full Text Available Potato (Solanum tuberosum L. is the major food and cash crop in the highland regions of Rwanda. However, farmers are not integrated into the potato breeding process. The objectives of this research were to identify farmers’ key potato production constraints and establish preferred traits in potato cultivar development in Rwanda. A participatory rural appraisal (PRA study was conducted through structured survey involving 144 households and 22 focus groups with 258 participants in Musanze, Gicumbi and Nyamagabe districts. The structured survey used a questionnaire administered to farmers to collect information on importance of potatoes and other main crops. While focus groups discussions used matrix scoring of key production constraints and pair-wise ranking of traits. Potato is the most important food and cash crop, followed by maize, beans and wheat. The dominant potato varieties are Kirundo, Cruza, Mabondo and Victoria. The most important potato production constraints are lack of access to credit, lack of high yielding cultivars, insufficient clean seeds and late blight disease. Variety Mabondo is the most tolerant to late blight, followed by Cruza, Kirundo, Kinigi and Rutuku in all the districts. High yield, disease tolerance and high dry matter content are the most important attributes preferred by farmers. Active farmer participation in early breeding stages is critical for a successful potato breeding programme.

  11. Genomics to benefit livestock production: improving animal health

    Directory of Open Access Journals (Sweden)

    Graham Stuart Plastow

    2016-06-01

    Full Text Available ABSTRACT The primary principle underlying the application of genomics is that it has the most value for difficult and expensive to measure traits. These traits will differ between species and probably also between markets. Maintenance of health will be one of the biggest challenges for efficient livestock production in the next few decades. This challenge will only increase in the face of demand for animal protein, resistance to existing drugs, and the pressure to reduce the use of antibiotics in agriculture. There is probably genetic variation in susceptibility for all diseases but little has been done to make use of this variation to date. In part this is because it is very difficult as well as expensive to measure this variation. This suggests that genomics should provide one of the ways of tackling the challenge of improving animal health. This paper will discuss the concepts of resistance, variation in susceptibility, and resilience; provide examples and present some recent results in cattle and pigs; and briefly discuss the application of gene editing in relation to disease resistance.

    International Nuclear Information System (INIS)

    Apart from our regular Coordinated Research Project (CRP) activities and our technical support given to ongoing national and regional Technical Cooperation (TC) projects, we were also involved in the formulation (together with our Member State counterparts and TC Country Officers) of projects for the 2009/11 TC project cycle. In addition to this, when carrying out our 2007 programme of work and budget performance evaluations, we could identify the areas where good performance was achieved as well as areas where further improvements are needed. It is hoped that our inputs will serve the best interests of our Member States. The focus of our activities is on enhancing food security by supporting sustainable livestock production systems in developing countries. This is to be achieved by strategic and applied research, technology transfer and capacity building. The three principal components of the subprogramme are animal nutrition, reproduction and breeding and animal health. Within these three components, problems are identified and solutions developed through the use of strategically applied nuclear-based tools, in conjunction with conventional technologies

  15. Product-line selection and pricing with remanufacturing under availability constraints

    Aras, Necati; Esenduran, G.÷k.‡e.; Altinel, I. Kuban

    2004-12-01

    Product line selection and pricing are two crucial decisions for the profitability of a manufacturing firm. Remanufacturing, on the other hand, may be a profitable strategy that captures the remaining value in used products. In this paper we develop a mixed-integer nonlinear programming model form the perspective of an original equipment manufacturer (OEM). The objective of the OEM is to select products to manufacture and remanufacture among a set of given alternatives and simultaneously determine their prices so as to maximize its profit. It is assumed that the probability a customer selects a product is proportional to its utility and inversely proportional to its price. The utility of a product is an increasing function of its perceived quality. In our base model, products are discriminated by their unit production costs and utilities. We also analyze a case where remanufacturing is limited by the available quantity of collected remanufacturable products. We show that the resulting problem is decomposed into the pricing and product line selection subproblems. Pricing problem is solved by a variant of the simplex search procedure which can also handle constraints, while complete enumeration and a genetic algorithm are used for the solution of the product line selection problem. A number of experiments are carried out to identify conditions under which it is economically viable for the firm to sell remanufactured products. We also determine the optimal utility and unit production cost values of a remanufactured product, which maximizes the total profit of the OEM.

  16. Lighting Energy Saving with Light Pipe in Farm Animal Production

    Directory of Open Access Journals (Sweden)

    Hans von Wachenfelt

    2015-12-01

    Full Text Available The Swedish animal production sector has potential for saving electric lighting of €4-9 million per year using efficient daylight utilisation. To demonstrate this, two light pipe systems, Velux® (house 1 and Solatube® (house 2, are installed in two identical pig houses to determine if the required light intensity, daylight autonomy (DA, and reduced electricity use for illumination can be achieved. In each house, three light sensors continuously measure the indoor daylight relative to an outdoor sensor. If the horizontal illuminance at pig height decreases below 40 lux between 08.00 and 16.00 hours, an automatic control system activates the lights, and electricity use is measured. The daylight factor (DF and DA are determined for each house, based on annual climate data. The mean annual DA of 48% and 55% is achieved for house 1 and house 2, respectively. Light pipes in house 2 have delivered significantly more DA than those in house 1. The most common illuminance range between 0 and 160 lux is recorded in both houses, corresponding to approximately 82% and 83% of daylight time for house 1 and house 2, respectively. Further, the daylighting system for house 2 has produced a uniform DF distribution between 0.05 and 0.59. The results demonstrate that considerable electric energy savings can be achieved in the animal production sector using light pipes. Saving 50% of electric lighting would correspond to 36 GWh or 2520 t CO2 per year for Sweden, but currently the energy savings are not making the investment profitable.

    Full Text Available practices and constraints to production of cabbage. A structured questionnaire was used to elicit information from cabbage farmers in Ashanti and Brong Ahafo regions where cabbage is intensively produced. The level of education among the respondents was low as only 10% had tertiary education. Majority of the respondents (68% did not own the lands they cultivated thus resulting in approximately 45% of them cultivating less than one acre of cabbage crop. Majority of cabbage farmers (62% planted cabbage on raised beds. Cabbage production in the study area was characterized by high use of inorganic fertilizer (NPK. Fifty-three percent (53% employed the use of watering cans in cabbage production. Farmers in their quest to mitigate the high Insect pest infestation; Hellula undalis, Plutella xylostella, Brevicoryne brassicae and Zonocerus variegatus, plant parasitic nematodes infection and pathological problems such as wilting of plants, leaf curl and leaf spots resorted to high frequency of pesticides application. It is expected that the information gathered from this baseline study would form the basis for the formulation and implementation of an integrated pest management (IPM strategy to enhance safe and environmentally sustainable production of cabbages. This would reduce environmental degradation and ensure maximum protection for humans, domestic animals and wild life.

  20. Water for animal products: a blind spot in water policy

    Science.gov (United States)

    Hoekstra, Arjen Y.

    2014-09-01

    We know from land, energy and climate studies that the livestock sector plays a substantial role in deforestation, biodiversity loss and climate change. More recently it has become clear that livestock also significantly contributes to humanity’s water footprint, water pollution and water scarcity. Jalava et al (Environ. Res. Lett. 9 074016) show that considerable water savings can be achieved by reducing the fraction of animal products in our diet. The findings are in line with a few earlier studies on water use in relation to diets. As yet, this insight has not been taken forward in national water policies, which focus on ‘sustainable production’ rather than ‘sustainable consumption’. Most studies and practical efforts focus on increasing water-use efficiency in crop production (more crop per drop) and feed conversion efficiency in the livestock sector (more meat with less feed). Water-use efficiency in the food system as a whole (more nutritional value per drop) remains a blind spot.

    2013-08-01

    Livestock keeping is the mainstay for the pastoral community while also providing social and cultural value. This study ranked main production constraints and cattle diseases that impacted livelihood and estimated herd prevalence, incidence rate, and impact of diseases on production parameters in a semiarid pastoral district of Narok in Kenya. Data collection employed participatory techniques including listing, pairwise ranking, disease incidence scoring, proportional piling, and disease impact matrix scoring and this was disaggregated by gender. Production constraints with high scores for impact on livelihood included scarcity of water (19%), lack of extension services (15%), presence of diseases (12%), lack of market for cattle and their products (10%), and recurrent cycle of drought (9%). Diseases with high scores for impact on livelihood were East Coast fever (ECF) (22%) and foot and mouth disease (FMD) (21%). High estimated incidence rates were reported for FMD (67%), trypanosomosis (28%), and ECF (15%), while contagious bovine pleuropneumonia (CBPP) had an incidence rate <1%. Milk yield was affected by FMD, ECF, and trypanosomosis, while ECF was the cause of increased mortality. FMD, ECF, CBPP, and brucellosis caused increased abortion, while effect of gender and location of study was not significant. Despite CBPP being regarded as an important disease affecting cattle production in sub-Sahara Africa, its estimated incidence rate in herds was low. This study indicates what issues should be prioritized by livestock policy for pastoral areas. PMID:23417827

    2014-12-01

    Full Text Available The objectives of this paper were to identify and describe husbandry practices, herd structure, owners’ trait preferences, breeding practices, and production constraints of camel in the two major camel rearing pastoral communities, viz. Afar and Somali, to generate baseline information that would help to plan possible breed improvement strategies and options for the different camel populations. The study sites were selected purposively while households from each of the sites randomly. Data were collected using formal questionnaires and focus group discussion. Results showed that average camel population per household was higher in Mille (28.06±2.27, Gode (27.51±2.02, and Moyale (24.07±2.13 districts. Female camel populations with age of >1 year contributes 78-83% of the total camel herd population in all the study districts. Higher number of female animals in the herd in the arid environment means providing continuous supply of milk and allows a rapid recovery of herd numbers after a disease outbreak or drought occurrence. This shows that pastoralists breeding objectives are in relation to the arid environment and female population in the herd. Most of the pastoral communities utilize a single breeding male camel per 40-50 female camels and this will affect productivity and heterogeneity of camel population. With regard to trait preference, all pastoral communities ranked milk yield as the first trait of choice, except Liben district in which adaptation trait was the primary preference. Growth trait ranked second in Mille, Gode, Liben, and Jijiga pastoral communities where as adaptation trait ranked second in Amibara and Shinille pastoral communities. The major camel production constraints were feed, diseases, and lack of water in that order and the major cause of the constraints was the recurrent drought occurred during the past 2-3 decades in the two regions. Therefore, in planning and implementation of the breeding strategies for small

    Globalisation has changed the veterinary profession in many ways and academic institutes may need to re-tool to help future professionals deal with the changes in a successful and productive way. The remarkably expanded and expanding volume of trade and traffic in animals and animal products means that to be effective veterinarians must grasp some of the complexities inherent in this trade. Being able to engage productively in cross-cultural dialogue will be important in negotiations over livestock shipments and also within the context of the delivery of medical services to companion animals in societies that are becoming increasingly diverse. Understanding the political landscapes that influence trade decisions will help to expedite agreements and facilitate the transfer of goods and materials that involve animal health. Disease emergence will continue to occur, and an awareness of the factors responsible and the response measures to undertake will help to contain any damage. PMID:20128459

    A comprehensive mathematical model description of anaerobic digestion of animal residues was developed, taking into account material and energy balances, kinetics, and economics of the process. The model has the flexibility to be applicable to residues from any size or type of animal husbandry operation. A computer program was written for this model and includes a routine for optimization to minimum unit gas cost, with the optimization variables being digester temperature, retention time, and influent volatile solids concentration. The computer program was used to determine the optimum base-line process conditions and economics for fuel gas production via anaerobic digestion of residues from a 10,000 head environmental beef feedlot. This feedlot at the conditions for minimum unit gas cost will produce 300 MCF/day of methane at a cost of $5.17/MCF (CH/sub 4/), with a total capital requirement of $1,165,000, a total capital investment of $694,000, and an annual average net operating cost of $370,000. The major contributions to this unit gas cost are due to labor (37 percent), raw manure (11 percent), power for gas compression (10 percent), and digester cost (13 percent). A conceptual design of an anaerobic digestion process for the baseline conditions is presented. A sensitivity analysis of the unit gas cost to changes in the major contributions to unit gas cost was performed, and the results of this analysis indicate areas in the anaerobic digestion system design where reasonable improvements could be expected so as to produce gas at an economically feasible cost. This sensitivity analysis includes the effects on unit gas cost of feedlot size and type, digester type, digester operating conditions, and economic input data.

  5. Evidence on the Adaptive Recruitment of Chinese Cork Oak (Quercus variabilis Bl.: Influence on Repeated Germination and Constraint Germination by Food-Hoarding Animals

    Full Text Available In drought temperate forest, seedling recruitment is highly dependent on seed burial by native animal dispersers. To prolong seed storage, animals often take measures to impede seed germination. Aiming to understand the strategic balance between the natural seed germination and the role played by animals in the constraint germination procedures, we investigated the stages on the germinated acorns of Chinese cork oak (Quercus variabilis Bl. and the rodents’ behavior on the consequential delay in developmental processes of acorns in Mt. Taihangshan area of Jiyuan, Henan, China. The results showed that (1 Apodemus peninsulae Thomas excise radicles from germinated acorns before hoarding; (2 radicle-excised acorns re-germinate successfully if the excised radicle was un-lignified, but reverse if excised radicle was lignified; and (3 seedlings derived from radicle-excised acorns produce more lateral roots than that of sound acorns. We conclude that rodents take the radicle-excision behavior as a deliberate mechanism to slow the rapid germination of acorns; nevertheless, the acorns adaptively respond to this negative treatment and counteract the constraint from rodents by regermination to preserve the viability of the seeds. Consequently, this plays a significant role in forest recruitment. This study proves the new survival model of Chinese cork oak against animal predation, and will broaden theories of animal-forest interaction, forest succession and can be used as a meaningful venture to temperate forest restoration efforts.

    Full Text Available The paper summarises the work done in the framework of two R&D projects aimed to demonstrate the contribution of Near Infrared Spectroscopy (NIRS to help the enforcement of the European legislation governing the use of animal by-products in animal feeds. Three different types of animal feed products were studied: compound feeds (CFs, animal protein byproducts meals (APBPs and animal fats by-products (AFBPs. The quantitative and qualitative chemometric models produced with a large collection of compound feed samples (n = 1005 ground and 523 unground have demonstrated, that NIRS can be used for the detection and quantification of the meat and bone meal (MBM added to compound feeds. Discriminant models produced with unground samples produced 100% of correctly classified samples in two cloned instruments placed in two different locations. The results also show that two dimensions NIR spectra of Animal By-Products (ABP, animal meals and fats may contain information about the animal species or group of species from which the ABPs were produced. However, further work is needed to enlarge the sample bank and the spectral libraries with well authenticated samples in order to increase the robustness of the quantitative and qualitative NIRS models. The paper opens expectations for using NIRS for the enforcement of legislation concerning the use of ABPs in animal feeds. More research and demonstration efforts have to be done in order to obtain more definitive and robust predictive models and for optimising its implementation either at-line, on-line and in-line in feed factories and inspection laboratories.

    Full Text Available This paper presents a model of management capacity in productive systems integrating the concepts of the Theory of Constraints and Total Productive Maintenance (TPM. The main objective of this study is to discuss and propose a model of management capacity, able to answer the following key questions: i capacity indicators which should be considered and how to measure them to measure the productive capacity of manufacturing systems? ii what is the real productive capacity of the system analyzed under a determined relationship between capacity and demand? The discussion of the proposed model is relevant because the definition of productive capacity system enables better management of resources and capabilities, improve production scheduling on the factory floor and meeting the demands imposed by the market. This paper presents the proposition of using the Operating Income Index Global (IROG with a different approach from traditional literature dealing with the theme, presented by Nakajima (1988. The results of this paper enable to develop a model to determine the capacity of the production system and the impact on the productive capacity of the entire system, not to consider the quality conformances that occur after the bottleneck resource of the production flow.

    A compilation has been undertaken of data which can be used to derive animal product transfer coefficients for radionuclides, including an extensive review of Russian language information. The resultant database has been used to provide recommended transfer coefficient values for a range of radionuclides to (i) cow, sheep and goat milk, (ii) meat (muscle) of cattle, sheep, goats, pigs and poultry and (iii) eggs. The values are used in a new IAEA handbook on transfer parameters which replaces that referred to as 'TRS 364'. The paper outlines the approaches and procedures used to identify and collate data, and assumptions used. There are notable differences between the TRS 364 'expected' values and the recommended values in the revised Handbook from the new database. Of the recommended values, three milk values are at least an order of magnitude higher than the TRS 364 values (Cr, Pu (cow) Pu (sheep)) and one milk value is lower (Ni (cow)). For meat, four values (Am, Cd, Sb (beef) I (pork)) are at least an order of magnitude higher than the TRS 364 values and eight values are at least an order of magnitude lower (Ru, Pu (beef), Ru, Sr, Zn (sheep), Ru, Sr (pork), Mn (poultry)). Many data gaps remain.

    The first phase of this year has been a busy time for all personnel in the Subprogramme. Apart from our regular Coordinated Research Project (CRP) activities and our technical support given to national and regional Technical Cooperation (TC) projects, we were involved in the technical planning of project concepts for new TC projects by Member States for the 2014/2015 biennial project cycle. We were also occupied with preparing the IAEA's 2014/2015 Work and Budget Programme, and the FAO's 2014/2015 Programme of Work and Budget. It is hoped that our inputs will serve the best interests of our Member States (MS). Please look at our web site and our Animal Production and Health Newsletter to familiarize yourselves with all the activities of the Subprogramme. A bone of contention is the current avian influenza H7N9 situation. On 1 April 2013, a human case of infection with the avian influenza H7N9 virus was reported in China. Since then this strain has been detected in four provinces of eastern China and has infected 132 people of which 37 have died (situation as of 3 June 2013). The number of cases dropped in May as compared to April, probably because of the control measures taken by Chinese health authorities, which includes closing live bird in markets, but this can also be due to the change climatic conditions or the international contribution

  12. Assessment of animal productivity and methane production using an associative feeding strategy

    International Nuclear Information System (INIS)

    Methane production from ruminants is a loss of digestible energy thereby reducing animal productivity and is contributing to environmental pollution. In order to develop a beneficial strategy for improving animal productivity while conserving the environment the present study was conducted to evaluate the effect of a concentrate feeding strategy on the animal productivity and rumen methane production. In this experiment two feeding regimes, Diet-1 and Diet-2, were either fodder alone and with a 10% inclusion of concentrates in the forage diet feed as a phased sequence of 45 days of fodder alone and then 45 days of fodder plus concentrate. The diets were fed to four animal groups comprising of 5 animals in each. Throughout the experimental period, a fresh, chopped fodder of similar age (50-65 days age) was offered to the animals. Average dry matter (DM), crude protein (CP), crude fibre (CF), ash and ether extract contents of the fodder were 21, 9.3, 31.7, 10.1 and 3.1%, respectively. Diet2 included a concentrate containing 88.0, 16.0, 8.1, 10.0, and 12.1% DM, CP, CF, Ash and EE, respectively. A decrease of 8.2 and 39.5% in group A and B with only minor a minor change in group C and D for feed intake was observed when the animals where feed Diet2. Weight gain for the four groups were 133, 422, 111 and 600 g per animal per day on Diet1 and 244, 688, 177 and 888 g per animal per day on Diet2 for groups A, B, C and D, respectively. With supplementation feeding strategy, there was an increase of 45.4, 38.7, 3.7 and 32.4% in weigh gain over fodder alone diet for groups A, B, C and D, respectively. This was associated with an improvement of 49.7, 62.9, 38.5 and 32% in feed to gain ratio for groups A, B, C and D, respectively. The DM digestibility was 22.9, 4.6, 4.7 and 8.4% higher in groups A, B, C and D, respectively when the groups were feed the fodder diets supplemented with concentrates. On fodder alone, the molar concentration of acetate, propionate, butyrate and

    A participatory epidemiological study was conducted to identify and prioritize constraints to livestock health and production on smallholder farms in Sanyati and Gokwe districts of Zimbabwe. Questionnaires were administered to 294 randomly selected livestock owners across the two districts. Livestock diseases (29% of the respondents), high cost of drugs (18.21%), weak veterinary extension (15.18%), inadequate grazing (13.60%), inadequate water (13.54%), and livestock thefts (10.44%) were the major livestock health and production constraints identified. The number of diseases reported varied (Psheep and goats, domestic chicken, donkeys, and guinea fowls, respectively. Seven (19.4%) of the 36 diseases including rabies and foot and mouth disease were those listed by the OIE. Thirty-four percent of the respondents rated bovine dermatophilosis as the most important livestock disease. Respondents rated, in descending order, other diseases including tick borne diseases (21%); a previously unreported disease, "Magwiriri" or "Ganda renzou" in vernacular (14%); mastitis (11%); parafilariosis (11%); and blackleg (9%). Cattle skin samples from "Magwiriri" cases had Besnoitia besnoiti parasites. Overall, this study revealed factors and diseases that limit livestock production in Zimbabwe and are of global concern; in addition, the study showed that the skin diseases, bovine dermatophilosis and besnoitiosis, have recently emerged and appear to be spreading, likely a consequence of ectoparasite control demise in smallholder farming areas of Zimbabwe over the last 15 years.

    Sub-Saharan Africa (SSA) experiences soil degradation, food and livelihood insecurity, environmental pollution and lack of access to energy. Biochar has gained international research attention, but few studies have investigated the potential of biochar to address the challenges in SSA. This paper seeks to identify and evaluate generic potential opportunities and constraints associated with biochar application in sub-Saharan Africa using Zimbabwe as case study. Specific objectives were to; (1) identify and quantify feedstocks for biochar production; (2) review literature on the biochar properties, and evaluate its potential applications in agriculture, environmental remediation and energy provision, and (3) identify research gaps, risks and constraints associated with biochar technology. Biochar feedstocks in Zimbabwe were estimated to be 9.9 Mton yr(-1), predominantly derived from manure (88%) and firewood (10%). This will yield 3.5, 1.7 and 3.1 Mton yr(-1) of biochar, bio-oil and synthetic gas, respectively. Land application of the 3.5 Mton yr(-1) of biochar (≈63% C) would sequester approximately 2.2 Mton yr(-1) of soil carbon in Zimbabwe alone, while simultaneously minimizing the environmental and public health risks, and greenhouse gas emissions associated with solid organic wastes. Biochar potentially enhances soil and crop productivity through enhanced nutrient and soil moisture availability, amelioration of acidic soils and stimulation of microbial diversity and activity. Due to its excellent adsorption properties, biochar has potential applications in industrial and environmental applications including water and wastewater treatment, remediation and revegetation of contaminated soils and water. Biochar products have energy values comparable or higher than those of traditional biomass fuels; thereby making them ideal alternative sources of energy especially for poor households without access to electricity. Before the benefits of biochar can be

    Full Text Available The farms of Western Pomerania province possess a large surplus of manpower. The dynamic optimization models with random constraints served the investigation of the possibilities of implementation of the unused man-hours. Those models regarded four successive years 2003-2006. The solution proceeded in two steps. The first step let us construct the assumption of the surplus or the deficiency of production factors. In the next step additional variables regarding the lease of arable grounds were introduced while the unused man-hours were implemented with various probability. The optimal solutions indicated the area of particular crops, the quantity of livestock and the farm income dependent on the use of the existing employment. This study aims at the presentation of the possibility of implementation of unused man-hours in farms dealing solely with the crop production and also the production of crop and livestock.

    The logistics network design is one of the important phase of Supply Chain Management (SCM) and it is the problem that should be optimized for long-term promotion of efficiency of the whole supply chain. Usually a plant produces different type of products. Even if it is a factory of the same company, delivery is different by a kind of a produced product. The restrictions which this model has are deeply concerned with TP in the real world. In this paper, we consider the logistics network design problems with multi-products and constraints for delivery course. To solve the problem, we used a hybrid priority-based Genetic Algorithm (h-priGA), and we tried the comparison experiment with priority-based Genetic Algorithm (priGA)and h-priGA, we show it about the effectiveness of h-priGA.

Amongst these technologies are the use of 13/14C, 125I, 3H, 32P, 35S to label protein and nucleic acid molecules for specific and sensitive detection, monitoring, and characterization of harmful pathogens that have made a critical contribution towards the development of e.g. ELISA, PCR, real-time PCR and sequencing. The subprogramme, furthermore, ensures the deployment and widespread use of applicable technologies in countries most at risk from climatically influenced infectious diseases. This technical support and guidance to countries (e.g. which test to use, when and for what purpose, equipment needs, staff training and proficiency, and quality management) played a vital role in building developing countries' capacities during recent outbreaks of avian influenza and Rift Valley Fever. The subprogramme has developed, implemented, and transferred immuno and molecular assays that are rapid, inexpensive and capable of being used to process large numbers of samples to detect infectious disease agents that adversely affect livestock productivity and prevent international trade. Four new CRPs started this year: The use of enzymes and nuclear technologies to improve the utilization of fibrous feeds and reduce greenhouse gas emission from livestock, control of foot-and-mouth disease, the use of irradiated vaccines in the control of infectious transboundary diseases of livestock and genetic variation on the control of resistance to infectious diseases in small ruminants for improving animal productivity.

    The current research of configurable product disassemblability focuses on disassemblability evaluation and disassembly sequence planning. Little work has been done on quantitative analysis of configurable product disassemblability. The disassemblability modeling technology for configurable product based on disassembly constraint relation weighted design structure matrix (DSM) is proposed. Major factors affecting the disassemblability of configurable product are analyzed, and the disassembling degrees between components in configurable product are obtained by calculating disassembly entropies such as joint type, joint quantity, disassembly path, disassembly accessibility and material compatibility. The disassembly constraint relation weighted DSM of configurable product is constructed and configuration modules are formed by matrix decomposition and tearing operations. The disassembly constraint relation in configuration modules is strong coupling, and the disassembly constraint relation between modules is weak coupling, and the disassemblability configuration model is constructed based on configuration module. Finally, taking a hydraulic forging press as an example, the decomposed weak coupling components are used as configuration modules alone, components with a strong coupling are aggregated into configuration modules, and the disassembly sequence of components inside configuration modules is optimized by tearing operation. A disassemblability configuration model of the hydraulic forging press is constructed. By researching the disassemblability modeling technology of product configuration design based on disassembly constraint relation weighted DSM, the disassembly property in maintenance, recycling and reuse of configurable product are optimized.

    2015-01-01

    Full Text Available This paper describes a method developed to schedule the preventive maintenance tasks of the generation and desalination units in separate and linked cogeneration plants provided that all the necessary maintenance and production constraints are satisfied. The proposed methodology is used to generate two preventing maintenance schedules, one for electricity and the other for distiller. Two types of crossover operators were adopted, 2-point and 4-point. The objective function of the model is to maximize the available number of operational units in each plant. The results obtained were satisfying the problem parameters. However, 4-point slightly produce better solution than 2-point ones for both electricity and water distiller. The performance as well as the effectiveness of the genetic algorithm in solving preventive maintenance scheduling is applied and tested on a real system of 21 units for electricity and 21 units for water. The results presented here show a great potential for utility applications for effective energy management over a time horizon of 52 weeks. The model presented is an effective decision tool that optimizes the solution of the maintenance scheduling problem for cogeneration plants under maintenance and production constraints.

    Production strategies definition, applied to petroleum fields, must consider physical, operational and economic constraints. It is common to consider only the reservoir conditions on the optimization processes, simplifying, many times, the process by not taking into account the operational constraints due to production facilities. There are two main reasons: considering the operational constraints makes the process much complex and it is assumed that this simplification can affect the economic indicators but dos not affect significantly the optimization process (number e location of wells, for example). The capacity of a production unit can be limited by many constrains such as: maximum liquid rate, capacity of water and gas treatment, gas compression, water or gas injection, number of wells, etc. In this work, we show that these limitations have a direct influence in the oil production and consequently in the economic indicators and they can cause significant impact at production strategy definition, influencing the number of production and injection wells, their locations and their operational conditions. We presented an example of an offshore field with a limitation on the liquid rate. Production strategies were selected with and without constraints in order to observe the differences in the technical and economic indicators, such as NPV (Net Present Value), production and injection of fluids and the number and location of the production and injection wells. It was possible to observe yet that the amount and location of the wells were significantly affected by the restriction. (author)

  11. Constraints on binary neutron star merger product from short GRB observations

    Gao, He; Lü, Hou-Jun

    2015-01-01

    Binary neutron star mergers are strong gravitational wave (GW) sources and the leading candidates to interpret short duration gamma-ray bursts (SGRBs). Under the assumptions that SGRBs are produced by double neutron star mergers, we use the statistical observational properties of {\\em Swift} SGRBs and the mass distribution of Galactic double neutron star systems to place constraints on the neutron star equation of state (EoS) and the properties of the post-merger product. We show that current observations already put following tight constraints: 1) A neutron star EoS with a maximum mass close to a parameterization of $M_{\\rm max} = 2.37\\,M_\\odot (1+1.58\\times10^{-10} P^{-2.84})$ is favored; 2) The fractions for the several outcomes of NS-NS mergers are as follows: $\\sim40\\%$ prompt BHs, $\\sim30\\%$ supra-massive NSs that collapse to BHs in a range of delay time scales, and $\\sim30\\%$ stable NSs that never collapse; 3) The initial spin of the newly born supra-massive NSs should be near the breakup limit ($P_i\\s...

    Emmerich, I U

    2011-01-01

    In 2010, three new active pharmaceutical ingredients were released on the German market for horses and food-producing animals. These were gamithromycin (Zactran®), a new macrolide antibiotic, Monepantel (Zolvix®), a broad spectrum anthelmintic with a novel mechanism, and Pergolide (Prascend®), the first dopamine receptor agonist for animals. Two substances have been approved for additional species. The tetracycline antibiotic doxycycline is now also authorized for turkeys and the nonsteroidal anti-inflammatory drug firocoxib from the group of cyclo-oxygenase-2 (COX-2) inhibitors is now available for horses. Furthermore, four new preparations with an interesting new pharmaceutical form, one drug with a new formulation and two drugs, which are interesting because of other criteria, were added to the market for horses and food producing animals.

  13. Nitrogen in global animal production and management options for improving nitrogen use efficiency

    Institute of Scientific and Technical Information of China (English)

    Oene; Oenema; Seerp; Tamminga

    2005-01-01

    Animal production systems convert plant protein into animal protein. Depending on animal species, ration and management, between 5% and 45 % of the nitrogen (N) in plant protein is converted to and deposited in animal protein. The other 55%-95% is excreted via urine and feces, and can be used as nutrient source for plant (= often animal feed) production. The estimated global amount of N voided by animals ranges between 80 and 130 Tg N per year, and is as large as or larger than the global annual N fertilizer consumption. Cattle (60%), sheep (12%) and pigs (6%) have the largest share in animal manure N production.The conversion of plant N into animal N is on average more efficient in poultry and pork production than in dairy production, which is higher than in beef and sheep production. However, differences within a type of animal production system can be as large as differences between types of animal production systems, due to large effects of the genetic potential of animals, animal feed and management. The management of animals and animal feed, together with the genetic potential of the animals, are key factors to a high efficiency of conversion of plant protein into animal protein.The efficiency of the conversion of N from animal manure, following application to land, into plant protein ranges between 0 and 60%, while the estimated global mean is about 15%. The other 40%- 100% is lost to the wider environment via NH3 volatilization, denitrification, leaching and run-off in pastures or during storage and/or following application of the animal manure to land. On a global scale, only 40%-50% of the amount of N voided is collected in barns, stables and paddocks, and only half of this amount is recycled to crop land. The N losses from animal manure collected in barns, stables and paddocks depend on the animal manure management system. Relative large losses occur in confined animal feeding operations, as these often lack the land base to utilize the N from animal

  19. Effects of microstructural constraints on the transport of fission products in uranium dioxide at low burnups

    Lim, Harn Chyi; Rudman, Karin; Krishnan, Kapil; McDonald, Robert; Dickerson, Patricia; Gong, Bowen; Peralta, Pedro

    2016-08-01

    Diffusion of fission gases in UO2 is studied at low burnups, before bubble growth and coalescence along grain boundaries (GBs) become dominant, using a 3-D finite element model that incorporates actual UO2 microstructures. Grain boundary diffusivities are assigned based on crystallography with lattice and GB diffusion coupled with temperature to account for temperature gradients. Heterogeneity of GB properties and connectivity can induce regions where concentration is locally higher than without GB diffusion. These regions are produced by "bottlenecks" in the GB network because of lack of connectivity among high diffusivity GBs due to crystallographic constraints, and they can lead to localized swelling. Effective diffusivities were calculated assuming a uniform distribution of high diffusivity among GBs. Results indicate an increase over the bulk diffusivity with a clear grain size effect and that connectivity and properties of different GBs become important factors on the variability of fission product concentration at the microscale.

  20. Constraints on ionising photon production from the large-scale Lyman-alpha forest

    Pontzen, Andrew; Peiris, Hiranya; Verde, Licia

    2014-01-01

    Recent work has shown that the z~2.5 Lyman-alpha forest on large scales encodes information about the galaxy and quasar populations that keep the intergalactic medium photoionized. We present the first forecasts for constraining the populations with data from current and next-generation surveys. At a minimum the forest should tell us whether galaxies or, conversely, quasars dominate the photon production. The number density and clustering strength of the ionising sources might be estimated to sub-10% precision with a DESI-like survey if degeneracies (e.g., with the photon mean-free-path, small-scale clustering power normalization and potentially other astrophysical effects) can be broken by prior information. We demonstrate that, when inhomogeneous ionisation is correctly handled, constraints on dark energy do not degrade.

    The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the fifth century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which are used as livestock feed. Ergot is found worldwide, with even low concentrations of alkaloids in the diet (ergotamine, ergocristine, ergosine, ergocornine, and ergocryptine is extremely variable within ergot bodies and the relative toxicity of these alkaloids has yet to be determined. This raises concerns that current recommendations on safe levels of ergot in feeds may be unreliable. Furthermore, the total ergot alkaloid content is greatly dependent on the geographic region, harvest year, cereal species, variety, and genotype. Considerable animal-to-animal variation in the ability of the liver to detoxify ergot alkaloids also exists and the impacts of factors, such as pelleting of feeds or use of binders to reduce bioavailability of alkaloids require study. Accordingly, unknowns greatly outnumber the knowns for cereal ergot and further study to help better define allowable limits for livestock would be welcome. PMID:26942186

    Antibodies made in large animals are integral to many biomedical research endeavors. Domesticated herd animals like goats, sheep, donkeys, horses and camelids all offer distinct advantages in antibody production. However, their cost of use is often prohibitive, especially where poor antigen response is commonplace; choosing a non-responsive animal can set a research program back or even prevent experiments from moving forward entirely. Over the course of production of antibodies from llamas, we found that some animals consistently produced a higher humoral antibody response than others, even to highly divergent antigens, as well as to their standard vaccines. Based on our initial data, we propose that these "high level responders" could be pre-selected by checking antibody titers against common vaccines given to domestic farm animals. Thus, time and money can be saved by reducing the chances of getting poor responding animals and minimizing the use of superfluous animals.

    2015-10-01

    Full Text Available There are significant environmental, economic and social factors favoring the reutilization of fruit and vegetable processing co-products in farm animal nutrition. Current evidence shows that fruit and vegetable processing co-products can be effectively used in farm animal nutrition as functional feed ingredients for the production of food products of improved quality. These ingredients comply with consumer requests for the production of “clean,” “natural” and “eco/green” label food products. The main parameters affecting extensive application of fruit and vegetable processing by-/co-products as functional feed ingredients in livestock nutrition are related to animal factors, logistics, and commercial value. Further research is needed to enable the commercial application of these products to livestock nutrition.

    Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built,...

    2005-01-01

    As shown by huge amount of assays in human as well as in animal models, w-3 polyunsaturated fatty acids play important role in the development and maintenance of different organs, primarily the brain, and could be useful in the prevention of different pathologies, mainly the cardiovascular diseases, and, as proposed recently, some psychiatric, dermatological or rheumatological disorders. For ALA, the major and cheapest source for human is rapeseed oil (canola oil), and walnut "noix de Grenoble" oil). The actual goal is first to identify which foods are naturally rich in w-3 fatty acids, and, second, to determine the true impact of the formulations (enriched in w-3 fatty acids) in chows used on farms and breeding centres on the nutritional value of the products and thus their effect on the health of consumers, thanks to quantities of either ALA, or EPA or DHA or both. This concern fish (in proportion of their lipid content, mainly mackerel, salmon, sardine and herring), eggs (wildly naturally rich in w-3 fatty acids, both ALA and DHA, or from laying hen fed ALA from linseed or rapeseed), meat from birds, mammals (from the highest concentration : rabbit, then pig and monogastrics, then polygastrics such as beef, mutton and goat) \\; in butter, milk, dairy products, cheese (all naturally poor in w-3 fatty acids)... Indeed, the nature of fatty acids of reserve triglycerides (found in more or less large amounts depending on the anatomical localisation, that is to say the butcher's cuts) can vary mainly as a function of the food received by the animal. EPA and DHA are mainly present in animal's products. The impact (qualitative and quantitative) of alterations in the lipid composition of animal foods on the nutritional value of derived products (in terms of EPA and DHA content) eaten by humans are more important in single-stomach animals than multi-stomach animals (due to their hydrogenating intestinal bacteria). The intestinal physiology of birds results in the

  1. Safety of Animal Fats for Biodiesel Production: A Critical Review of Literature

    Greene, A.; Dawson, P.; Nixon, D.; Atkins, J.; Pearl, G. [Clemson University, SC (United States)

    2007-05-15

    An in-depth review of available literature was conducted on the safety of using animal fats for biodiesel. The review indicated little or no known risk to human and animal health and to the environment relative to inherent microbial, organic or inorganic agents in animal fats destined for biodiesel production. Animal by-products are generated from the inedible tissues derived from meat, poultry and fish production. This material is thermally processed by the rendering industry to generate a number of industrial materials including use of the fat portion to produce biodiesel. As the biodiesel industry continues to develop, questions have emerged about the safety of animal versus vegetable fats for biodiesel production and utilization. The following report is the result of a detailed literature search into the potential microbial, organic, and inorganic contaminants that may be present in animal fats and the potential for human or environmental safety issues associated with each. The potential safety risks associated with prions are discussed in a separate report, 'Biodiesel from Specified Risk Material Tallow: An Appraisal of TSE Risks and their Reduction'. In certain instances, very little was reported about the potential contaminating moiety and its fate in biodiesel production and usage. Establishing an absolute zero risk assessment is impossible on any fat utilized for biodiesel production. Among the potential microbial contaminants, bacteria, viruses, fungi, yeast, parasites, and microbial toxins were considered. In each instance, the nature of the production process and usage of biodiesel via combustion reduce the possibility that microbial contaminants would be a cause for concern to humans, animals, or the environment. Potential organic moieties contaminating the fat should meet a similar fate. Current evidence suggests that metals and metalloids within animal fats will not cause significant safety issues in the production and use of rendered fat

  2. Antibiotic resistance--consequences for animal health, welfare, and food production.

    Bengtsson, Björn; Greko, Christina

    2014-05-01

    Most of the literature on the consequences of emergence and spread of bacteria resistant to antibiotics among animals relate to the potential impact on public health. But antibiotics are used to treat sick animals, and resistance in animal pathogens may lead to therapy failure. This has received little scientific attention, and therefore, in this article, we discuss examples that illustrate the possible impact of resistance on animal health and consequences thereof. For all animals, there may be a negative effect on health and welfare when diseases cannot be treated. Other consequences will vary depending on why and how different animal species are kept. Animals kept as companions or for sports often receive advanced care, and antibiotic resistance can lead to negative social and economic consequences for the owners. Further, spread of hospital-acquired infections can have an economic impact on the affected premises. As to animals kept for food production, antibiotics are not needed to promote growth, but, if infectious diseases cannot be treated when they occur, this can have a negative effect on the productivity and economy of affected businesses. Antibiotic resistance in animal bacteria can also have positive consequences by creating incentives for adoption of alternative regimes for treatment and prevention. It is probable that new antibiotic classes placed on the market in the future will not reach veterinary medicine, which further emphasizes the need to preserve the efficacy of currently available antibiotics through antibiotic stewardship. A cornerstone in this work is prevention, as healthy animals do not need antibiotics.

It is expected that FAO and OIE will jointly declare the world to be free from Rinderpest in 2011. In commemoration of this, I want to pay tribute to the members that made this possible such as regional organizations (EC, AU/IBAR CG-Centres etc), international organizations (FAO, OIE, IAEA etc), individual countries (France, Japan, The Netherlands, United Kingdom, United States of America, Italy etc) and the Member States that suffered from this disease and worked towards its eradication. Together with all the role players, the Joint FAO/IAEA Division and the IAEA Technical Cooperation Department's contribution to the development, evaluation and validation of nuclear and nuclear related immunological and molecular diagnostic technologies was a niche and critical area. The International Atomic Energy Agency (IAEA) has two mechanisms of technical support to Member States - the development, evaluation and validation of nuclear and nuclear related technologies through the Coordinated Research Project (CRP) mechanism, and the transfer and sustainable implementation of the CRP developed technologies through the IAEA's Technical Cooperation Project (TCP) mechanism. The development of nuclear and nuclear related immunological and molecular diagnostic technologies were jointly developed between CRPs of the Joint FAO/IAEA Division and TCPs of the Technical Cooperation Department

    Argument In the 1940s-50s, one of the most central questions in psychological research related to the nature of neurosis. In the final years of the Second World War and the following decade, neurosis became one of the most prominent psychiatric disorders, afflicting a high proportion of military casualties and veterans. The condition became central to the concerns of several psychological fields, from psychoanalysis to Pavlovian psychology. This paper reconstructs the efforts of Chicago psychiatrist Jules Masserman to study neurosis in the laboratory during the 1940s and 1950s. Masserman used Pavlovian techniques in a bid to subject this central psychoanalytic subject to disciplined scientific experimentation. More generally, his project was an effort to bolster the legitimacy of psychoanalysis as a human science by articulating a convergence of psychoanalytic categories across multiple species. Masserman sought to orchestrate a convergence of psychological knowledge between fields that were often taken to be irreconcilable. A central focus of this paper is the role of moving images in this project, not only as a means of recording experimental data but also as a rhetorical device. The paper argues that for Masserman film played an important role in enabling scientific observers (and then subsequent viewers) to see agency and emotion in the animals they observed. PMID:26903373

  5. Biodrying of animal slaughterhouse residues and heat production

    Animal carcasses from slaughterhouses are usually composted on farms, but the composting process is not optimized and a large volumes of carbonaceous residues are needed. This type of composting takes place over a period of 6 to 9 months in a nonaerated static pile. Quebec's industrial research centre (CRIQ) developed an organic biodrying process (BIOSECO) adapted to large-scale operations in order to optimize the treatment of slaughterhouse residues. Biodrying is a form of composting, in which the thermophilic phase is optimized, making it possible to evaporate large amounts of water. Biodrying is done inside a building and reduces the amount of carbonaceous residues considerably. The process is optimized by the sequence in which the slaughterhouse residues are added, the choice of input and the aeration flow. Slaughterhouse residues can be treated non-stop throughout the entire year. Since the odours are nearly completed limited to the building, the biodrying can be done near the slaughterhouse. A large amount of heat was produced by the process during the pilot project. It was concluded that the BIOSECO biodrying process is suitable for treating slaughterhouse residues in an effective and economic manner, and has the added advantage of producing heat that could be used for various purposes.

  6. Animal production and health newsletter. No. 47, December 2007

    International Nuclear Information System (INIS)

    As part of the Agency's 2006/7 Programme of Work and Budget, we evaluated our regular Co-ordinated Research Project (CRP) activities and our technical support given to ongoing national and regional Technical Co-operation projects (TCPs) and focussed our activities for the Agency's 2008/9 cycle. During this exercise we could identify areas where good performance was achieved as well as those where further improvements were needed ? and which we then addressed. We also had time to reflect on our past performance in order to serve the best interests of our Member States. It became apparent that the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has to be more proactive towards the detection, control and management of emerging diseases, with particular emphasis on transboundary animal diseases and the offering of relevant and effective support to MS. Attention was given to increasing our collaboration with other International Organisations (such as OIE, WHO and CGIAR Centres) as well as our Joint FAO/IAEA divisional activities. The clear advantage that we as a Joint FAO/IAEA programme have is a very proficient laboratory (and expertise) that focuses on our direct support to MS. To this effect this Issue want to highlight our activities related to small ruminant reproduction and breeding in this section of the newsletter

    The present study assessed the benefits of integration of animals with fish production in optimizing the bio mass production from unit land in subtropical hill agro ecosystem. Hampshire pigs and Khaki Campbell ducks were integrated with composite fish culture. The pig and duck excreta were directly allowed into the pond and no supplementary feed was given to fish during the period of study. The average levels of N, P and K in dried pig and duck manure were 0.9, 0.7 and 0.6 per cent and 1.3, 0.6 and 0.5 per cent, respectively. The average body weight of pig and duck at 11 months age was 90 and 1.74 kg with an average daily weight gain of 333.33 and 6.44 g, respectively. The fish production in pig-fish and duck-fish systems were 2209 and 2964 kg/ha, respectively while the fish productivity in control pond was only 820 kg/ha. The total biomass (animal and fish) production was higher (p<0.05) in commercial feeding system compared to the traditional system, however the input/output ratio was 1:1.2 and 1:1.55 for commercial and traditional systems, respectively. It was inferred that the total biomass production per unit land was high (p<0.05) when animal and fish were integrated together.

    Ammonia (NH3) emissions from livestock production in China are an important contributor to the global NH3 budget. In this study, by estimating total nitrogen (N) intake based on herd structures and excreted N, a mass balance model was used to estimate NH3 losses from animal housing and manure storage facilities of dairy cattle, beef cattle, pigs, broiler and layer productions within animal farm gate and their corresponding NH3 emission intensities on the basis of animal products, N and protein in animal products. In 2009, NH3 emissions from pigs, layers, beef and dairy cattle and broiler production systems in China were 1.23, 0.52, 0.24, 0.21 and 0.09 million tons, respectively. The NH3 emission intensities were 26.6 g NH3-N kg-1 of pork, 28.1 g NH3-N kg-1 of layer eggs, 39.4 g NH3-N kg-1 of beef meat, 6.0 g NH3-N kg-1 of dairy milk and 4.6 g NH3-N kg-1 of chicken meat, or 1260 (pigs), 1514 (layers), 1297 (beef), 1107 (dairy) and 123 g NH3-N (broilers) kg-1 N in animal products. Of the sectors of NH3 emission, manure storage facilities and farmyard manure (FYM) in animal housing were the major contributors to the total NH3 emissions except for layers; housing emissions from slurry were also major contributors for dairy and pig production.

    2013-01-01

    We investigate the observational constraints on the inhomogeneous big-bang nucleosynthesis that Matsuura et al. suggested the possibility of the heavy element production beyond ${}^7$Li in the early universe. From the observational constraints on light elements of ${}^4$He and D, possible regions are found on the plane of the volume fraction of the high density region against the ratio between high-and low-density regions. In these allowed regions, we have confirmed that the heavy elements beyond Ni can be produced appreciably, where $p$- and/or $r$-process elements are produced well simultaneously.

    In order to promote the common development of grain production and animal husbandry, and achieve the optimal comprehensive benefit of the entire system of grain production and the development of animal husbandry, we use the method of game theory to research the relations between grain production and the development of animal husbandry, from the perspective of interests cointegration. In accordance with the internal relations between stakeholders in grain production and the development of animal husbandry, we focus on researching the interests-sharing game behavior of the government and planting subject collectives, the planting subject collectives and planting subject individuals, the breeding subject and planting subject. The results show that there is inequality between various stakeholders, and they seek not only the price-based benefit, but also some intangible interests difficult to calculate and quantify.

    The radionuclides {sup 14}C and {sup 3}H may both be released from nuclear facilities. These radionuclides differ from most others in that they are isotopes of macro-elements which form the basis of animal tissues, feed and, in the case of {sup 3}H, water. There are few published values describing the transfer of {sup 3}H and {sup 14}C from feed to animal derived food products. Approaches are described which enable the prediction of {sup 14}C and {sup 3}H transfer parameter values from readily available information on the stable H or C concentration of animal feeds, tissues and milk, water turnover rates, and feed intakes and digestibilities. It is recommended that the concentration ratio between feed and animal product activity concentrations be used as it is less variable than the transfer coefficient (ratio between radionuclide activity concentration in animal milk or tissue to the daily intake of a radionuclide).

  20. FAO/IAEA international symposium on sustainable improvement of animal production and health. Synopses

    International Nuclear Information System (INIS)

    The on-going 'Livestock Revolution', a demand-driven increase in livestock production, especially in developing countries, presents both opportunities and risks. The shift in the human diet from plant-based protein sources to animal-based protein sources, consumer demand for safe and quality animal products, and expanding markets for livestock products have raised several challenges such as; cost-effective production of safe and quality animal products, control of emerging and zoonotic diseases, and efficient management of impact of livestock on the environment. However, these changes have also provided many opportunities to benefit the local economy and producers, and reduce poverty. New challenges and opportunities demand innovative ideas and approaches, and mechanisms to take this knowledge to potential users. Many of the approaches will be multidisciplinary in nature and require collaboration with specialists in areas other than animal scientists. Livestock production in developing countries is constrained by low genetic potential of animals, poor nutrition, poor husbandry and infectious diseases. Nuclear techniques, when applied in conjunction with conventional methods, can identify critical points in these areas that can be targeted for cost-effective improvements and interventions. Thus the challenge is to use such technologies to enhance food security and alleviate poverty by supporting sustainable livestock production systems in developing countries through strategic and applied research, technology transfer and capacity building. Topics addressed at the symposium: - Interactions among nutrition, reproduction and genotype; - Livestock-environment interaction / productivity/ climate (water/ land/ plants/heat/ altitude); - Detection and control of transboundary animal diseases, including zoonoses; - Animal product safety and food quality. Each of the papers published in this book of synopses has been indexed separately

    International Nuclear Information System (INIS)

    Once again the year is at end and a new exciting year lies ahead of us. The past year has been a busy time for all staff in the subprogramme. Apart from our regular Coordinated Research Project (CRP) activities and our technical support given to national and regional Technical Cooperation (TC) projects, we were involved in the technical evaluation of applications for new TC projects by Member States for the 2007/2008 biennial project cycle. We have also prepared the IAEA's 2008/2009 Work and Budget Programme. It is hoped that our inputs will serve the best interests of our Member States. As with previous newsletters, I want to introduce a topic to hopefully stimulate discussion and debate and encourage interactions between all. It has been well discussed in previous newsletters that the trend towards intensification of livestock production in developing countries presents both opportunities and risks. The potential opportunities are the flow-on benefits to the local economy and producers and the potential risks are the flow-on costs to the environment, livestock health and welfare and human health, through increased chemical and nutrient pollution, disease transmission and centralization of feed resources. Understanding nutrition is one of the keys to taking advantage of the opportunities and minimizing the risks

  8. I-124 production using nanomaterials and its biodistribution in animals

    International Nuclear Information System (INIS)

    Iodine-124 is a positron emitter with physical half-life of 4.2 days. Its decay occurs by positron emission (23.3%) and electron capture (76.7%). Their physical and chemical characteristics make it an attractive isotope for medical applications. The development of new imaging techniques, improvements in Positron Emission Tomography (PET), the development of new detectors and computational methods of signal processing, open new perspectives for its application. The increasing use of PET technology in medical oncology, pharmacokinetics and drug metabolism, make the radiopharmaceuticals labeled with 124I a tool of great interest and usefulness. The use of 124I - labeled molecules stands out particularly due to the convenient half-life of 124I. This feature enables diagnostic imaging in PET centers far away from the radionuclides producing center. Within this context, this work presents a method for the production and separation of 124I. This method is innovative and pioneering in the country. It is based on the development and use of nanostructured targets of natTeO2. These targets are irradiated in a charged particles accelerator, with variable energy, the IEN's CV-28 cyclotron. The irradiations are performed with 24 MeV, initial energy, proton beams. In the preparation of nanoparticulated targets the highlight was the simplicity of the method that uses the sol-gel technique for obtaining nanoparticles, TeCl4 as precursor and water as solvent. The produced 124I was separated from the target material by dry distillation and trapped in a NaOH solution (0.02 M), in an automated system. The thick target yield was 6.81 MBq/μAh, and the synthesis yield was 90%. The 124I obtained was then used in preliminary biodistribution studies. These studies were performed on a micro PET, model Lab PET 4 of the CDTN, in Swiss type mice. The results of the application of Na124I showed high quality PET imaging of the thyroid, with the maximum uptake at 6 h after injection. (author)

    This article takes a future focus on the direction in which social forces develop the market for animal-friendly products in Europe. On the basis of qualitative data gathered in the context of the European EconWelfare project, the differences across eight European countries are studied. The findings suggest that, given international trade barriers that prevent an improvement of animal welfare through legislation, many stakeholders believe that the market is the most viable direction to improve farm animal welfare. Economic productivity of the chain remains, however, an issue that on a fundamental level conflicts with the objective to improve animal welfare. With the help of a deeper conceptual understanding of willingness to pay for animal welfare, the paper finds that the European market for animal-friendly products is still largely fragmented and that the differences between European countries are considerable. A more animal-friendly future that is achieved through the market will therefore need substantial policy attention from stakeholders in society.

  11. Combustion of animal or vegetable based liquid waste products; Foerbraenning av flytande animaliska/vegetabiliska restprodukter

    Wikman, Karin; Berg, Magnus [AaF-Energikonsult AB, Stockholm (Sweden)

    2002-04-01

    In this project experiences from combustion of animal and vegetable based liquid waste products have been compiled. Legal aspects have also been taken into consideration and the potential for this type of fuel on the Swedish energy market has been evaluated. Today the supply of animal and vegetable based liquid waste products for energy production in Sweden is limited. The total production of animal based liquid fat is about 10,000 tonnes annually. The animal based liquid waste products origin mainly from the manufacturing of meat and bone meal. Since meat and bone meal has been banned from use in animal feeds it is possible that the amount of animal based liquid fat will decrease. The vegetable based liquid waste products that are produced in the processing of vegetable fats are today used mainly for internal energy production. This result in limited availability on the commercial market. The potential for import of animal and vegetable based liquid waste products is estimated to be relatively large since the production of this type of waste products is larger in many other countries compared to Sweden. Vegetable oils that are used as food or raw material in industries could also be imported for combustion, but this is not reasonable today since the energy prices are relatively low. Restrictions allow import of SRM exclusively from Denmark. This is today the only limit for increased imports of animal based liquid fat. The restrictions for handle and combustion of animal and vegetable based liquid waste products are partly unclear since this is covered in several regulations that are not easy to interpret. The new directive for combustion of waste (2000/76/EG) is valid for animal based waste products but not for cadaver or vegetable based waste products from provisions industries. This study has shown that more than 27,400 tonnes of animal based liquid waste products and about 6,000 tonnes of vegetable based liquid waste products were used for combustion in Sweden

    Directory of Open Access Journals (Sweden)

    Thamsborg SM

    2002-03-01

    Full Text Available Organic farming (or ecological agriculture is of growing importance in the agricultural sector worldwide. In the Nordic countries, 1–10% of the arable land was in organic production in 1999. Organic farming can be seen as an approach to agriculture where the aim is to create integrated, humane, environmentally and economically sustainable agricultural production systems. Principles like nutrient recycling, prevention rather than treatment and the precautionary principle are included in aims and standards. Animal welfare is another hallmark of organic livestock production but despite this, several studies have indicated severe health problems e.g. in organic poultry production in Denmark. Also the quality of animal food products in relation to human health, particularly the risk of zoonotic infections, has been debated. For these reasons there is a need for improvement of production methods and animal health status. Vets play an important role in this development through work in clinical practice and in research. On-farm consultancy should be tailored to the individual farmers needs, and the practitioner should be willing to take up new ideas and when needed, to enter a critical dialogue in relation to animal welfare. Better base line data on animal health and food safety in organic food systems are needed.

    Certain string-inspired Z' models have non-universal interactions to three families of fermions and induced tree-level flavor-changing couplings. We use recent results on B_s-anti-B_s mixing to constrain the size of the flavor-changing couplings in the b-s sector. In some highly predictive Z' models, such a constraint on b-s coupling can be translated into the flavor-diagonal couplings. Based on the Z' production limits at the Tevatron, we obtain the limit on the leptonic couplings of Z' and then make predictions for B_s -> \\mu^+ \\mu^- branching ratios. We conclude that with the present constraints from B_s mixing and Z' production, the muonic decay of $B_s$ may not be observed at the Tevatron if the projected integrated luminosity is less than O(5-10) fb.

We conclude that with the present constraints from Bs mixing and Z' production, the muonic decay of Bs may not be observed at the Tevatron if the projected integrated luminosity is about O(5-10) fb-1

    Babo Martins, S; Rushton, J

    2014-12-01

    Cost-effectiveness analysis (CEA) has been extensively used in economic assessments in fields related to animal health, namely in human health where it provides a decision-making framework for choices about the allocation of healthcare resources. Conversely, in animal health, cost-benefit analysis has been the preferred tool for economic analysis. In this paper, the use of CEA in related areas and the role of this technique in assessments of animal health, welfare and production are reviewed. Cost-effectiveness analysis can add further value to these assessments, particularly in programmes targeting animal welfare or animal diseases with an impact on human health, where outcomes are best valued in natural effects rather than in monetary units. Importantly, CEA can be performed during programme implementation stages to assess alternative courses of action in real time.

  20. Salmonella Isolated from Animals and Feed Production in Sweden Between 1993 and 1997

    2003-12-01

    Full Text Available This paper presents Salmonella data from animals, feedstuffs and feed mills in Sweden between 1993 and 1997. During that period, 555 isolates were recorded from animals, representing 87 serotypes. Of those, 30 serotypes were found in animals in Sweden for the first time. The majority of all isolates from animals were S. Typhimurium (n = 91, followed by S. Dublin (n = 82. There were 115 isolates from cattle, 21 from broilers, 56 from layers and 18 from swine. The majority of these isolates were from outbreaks, although some were isolated at the surveillance at slaughterhouses. The number of isolates from the feed industry was similar to that of the previous 5-year period. Most of those findings were from dust and scrapings from feed mills, in accordance with the HACCP programme in the feed control programme. It can be concluded that the occurrence of Salmonella in animals and in the feed production in Sweden remained favourable during 1993–97.

  2. Constraints under organic farming on French sheepmeat production: a legal and economic point of view with an emphasis on farming systems and veterinary aspects.

    Benoit, Marc; Laignel, Gabriel

    2002-01-01

    Ovine meat production in France, which is continually regressing due to economic difficulties, is based on two main production systems. The first system is located in plains in which one part of the lambs born in the spring are fed grass, and the other part of the lambs are from out of the season parturitions following hormonal treatments and are fattened in sheep houses. The second system is represented by farms in the mountains using hardy breeds which have a natural faculty for out of the season breeding and whose lambs are fattened indoors, whatever the season of birth. Amongst the sanitary problems encountered, parasitism in particular of young animals, is crucial, especially for farms on plains practising grass fattening. These farmers systematically use conventional anthelmintic treatments, in particular against Moniezia and Strongyles. With organic farming, the limited number of conventional anthelmintic treatments is a strong constraint, especially for the management of young grass-fed animals. A study of 10 organic farming farms or farms converting to organic farming (six in the mountains and four in the plains) showed that the size of these farms is inferior to that of conventional ones and have technical performances which are comparable to the average with 20 to 30% extra over-prices on lamb sales. Despite this, the gross margins per ewe in organic farming are equal to the average of those for conventional farms. This is due to the high consumption of concentrate at a high cost (50 to 100% greater than that for conventional farms). Finally, to prevent sanitary risks, certain organic farmers use important amounts of feed supplements containing phytotherapy products whose costs burden a part of the financial results of the farm. On the contrary, other organic farmers are able, by adapting breeding and grazing managements, to significantly decrease animal health costs without increasing feed supplements nor decreasing zootechnical performances.

    Venom represents one of the most extreme manifestations of a chemical arms race. Venoms are complex biochemical arsenals, often containing hundreds to thousands of unique protein toxins. Despite their utility for prey capture, venoms are energetically expensive commodities, and consequently it is hypothesized that venom complexity is inversely related to the capacity of a venomous animal to physically subdue prey. Centipedes, one of the oldest yet least-studied venomous lineages, appear to defy this rule. Although scutigeromorph centipedes produce less complex venom than those secreted by scolopendrid centipedes, they appear to rely heavily on venom for prey capture. We show that the venom glands are large and well developed in both scutigerid and scolopendrid species, but that scutigerid forcipules lack the adaptations that allow scolopendrids to inflict physical damage on prey and predators. Moreover, we reveal that scolopendrid venom glands have evolved to accommodate a much larger number of secretory cells and, by using imaging mass spectrometry, we demonstrate that toxin production is heterogeneous across these secretory units. We propose that the differences in venom complexity between centipede orders are largely a result of morphological restrictions of the venom gland, and consequently there is a strong correlation between the morphological and biochemical complexity of this unique venom system. The current data add to the growing body of evidence that toxins are not expressed in a spatially homogenous manner within venom glands, and they suggest that the link between ecology and toxin evolution is more complex than previously thought.

  7. Leaf chlorophyll constraint on model simulated gross primary productivity in agricultural systems

    Houborg, Rasmus

    2015-05-05

    Leaf chlorophyll content (Chll) may serve as an observational proxy for the maximum rate of carboxylation (Vmax), which describes leaf photosynthetic capacity and represents the single most important control on modeled leaf photosynthesis within most Terrestrial Biosphere Models (TBMs). The parameterization of Vmax is associated with great uncertainty as it can vary significantly between plants and in response to changes in leaf nitrogen (N) availability, plant phenology and environmental conditions. Houborg et al. (2013) outlined a semi-mechanistic relationship between V max 25 (Vmax normalized to 25 °C) and Chll based on inter-linkages between V max 25 , Rubisco enzyme kinetics, N and Chll. Here, these relationships are parameterized for a wider range of important agricultural crops and embedded within the leaf photosynthesis-conductance scheme of the Community Land Model (CLM), bypassing the questionable use of temporally invariant and broadly defined plant functional type (PFT) specific V max 25 values. In this study, the new Chll constrained version of CLM is refined with an updated parameterization scheme for specific application to soybean and maize. The benefit of using in-situ measured and satellite retrieved Chll for constraining model simulations of Gross Primary Productivity (GPP) is evaluated over fields in central Nebraska, U.S.A between 2001 and 2005. Landsat-based Chll time-series records derived from the Regularized Canopy Reflectance model (REGFLEC) are used as forcing to the CLM. Validation of simulated GPP against 15 site-years of flux tower observations demonstrate the utility of Chll as a model constraint, with the coefficient of efficiency increasing from 0.91 to 0.94 and from 0.87 to 0.91 for maize and soybean, respectively. Model performances particularly improve during the late reproductive and senescence stage, where the largest temporal variations in Chll (averaging 35–55 μg cm−2 for maize and 20–35 μg cm−2 for soybean) are

    Land-based production of high-quality protein by livestock and poultry plays an important role in improving human nutrition, growth, and health, as well as economical and social developments worldwide. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase by 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting the increasing needs for animal products and mitigating undesired effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Breeding techniques may help achieve this goal, but have only met with limited success. A promising, mechanism-based approach is to optimize the proportion and amounts of amino acids in diets for maximizing whole-body protein synthesis and feed efficiency. Improvements in farm animal productivity will not only decrease the contamination of soils, groundwater, and air by excessive manure, but will also help sustain animal agriculture to produce high-quality protein for the expanding population in the face of diminishing resources.

    Full Text Available For starting a long term programmes in Croatian animal production, formation of "economic unities" is necessary. Presentation and explanation of production and trade unity for animal production and marketing with subjects and phases is given here. It is pointed out that production of slaughter animals and meat is key interest of market and economic policy as well as of development of agricultural country. It seems that production and trade of meat in Croatia is not organized enough in overall market competition and in meat processing. Creating the economic unity of production and trade of slaughter animals can help in relative fast and efficient solving of problems accumulated in agriculture, especialy in meat production (PIK Vrbovec, Danica, Bejle etc. For initiating and getting in function the phases of production and trade of slaughter animals and meat, proper legislation should be introduced. This legislation should comprehencively define the idea of agricultural economy as a subject of legislative and normisation acts for overall, process and market oriented functioning of multidisciplinary agricultural systems. Additionaly, law on trade of slaughter animals, meat and agricultural products should be introduced in order to form a market and determine the share and obligations of certain participants in structure of such market.

A total of nineteen (19 constraints of varying importance across agro-ecological zones were identified among which the most important were insects’ damages on both leaves and tubers, nematodes attack on tubers, drought, soil poverty and wilting. For the majority (78.94% of the constraints, the use of tolerant cultivars remains the most sustainable, economically profitable and environment preservative solution. Farmers’ cultivar preference criteria identified are many (24 in total. Among them, high productivity, good quality of pounded yam, resistance to drought and adaptability to all types of soils are the most important. A perfect match is noted between enumerated constraints and identified preference criteria. The knowledge of farmers’ selection criteria is of capital importance for breeders and also extension services for eventual yam cultivar exchange between agroecological zones in Togo.

  14. Operation and control of flow manufacturing based on constraints management for high-mix/low-volume production

    2008-01-01

    The existing technology of flow manufacturing, which is mainly appropriate for high volume and repetitive production, is proven difficult to be applied in high-mix/ low-volume environments. To adapt lean production into the latter, a new type of flow manufacturing is proposed based on flow path management technology. This paper first describes the general operation framework of the pro-posed new mode. The main idea is the dynamic formation of adaptable virtual production lines (called flow paths) corresponding to different product families. The applica-tion of different theories of constraints/drum-buffer-rope (TOC/DBR) control policies depends on the differences in scope of variety and scale of demand for these product families. The overall architecture of the proposed mech-anism of constraint management-based operation and con-trol is introduced. For the implementation, a mathematical programming method is suggested for the dynamic plan-ning of flow paths, and a TOC/DBR 'path-specific' mech-anism with group scheduling is used for the control over each flow path. We also study other critical issues including the identification and management of resource bottlenecks, and the setting of the buffer size in the deployment of the TOC/DBR mechanism.

    2014-11-01

    In this study, corn oil as vegetable oil, chicken fat and fleshing oil as animal fats were used to produce methyl ester in a biodiesel pilot plant. The FFA level of the corn oil was below 1% while those of animal fats were too high to produce biodiesel via base catalyst. Therefore, it was needed to perform pretreatment reaction for the animal fats. For this aim, sulfuric acid was used as catalyst and methanol was used as alcohol in the pretreatment reactions. After reducing the FFA level of the animal fats to less than 1%, the transesterification reaction was completed with alkaline catalyst. Due to low FFA content of corn oil, it was directly subjected to transesterification. Potassium hydroxide was used as catalyst and methanol was used as alcohol for transesterification reactions. The fuel properties of methyl esters produced in the biodiesel pilot plant were characterized and compared to EN 14214 and ASTM D6751 biodiesel standards. According to the results, ester yield values of animal fat methyl esters were slightly lower than that of the corn oil methyl ester (COME). The production cost of COME was higher than those of animal fat methyl esters due to being high cost biodiesel feedstock. The fuel properties of produced methyl esters were close to each other. Especially, the sulfur content and cold flow properties of the COME were lower than those of animal fat methyl esters. The measured fuel properties of all produced methyl esters met ASTM D6751 (S500) biodiesel fuel standards.

    Full Text Available The permanent productions in Caraş- Severin county take the second place in terms of surface on national level and represent over 70% of the county surface. The natural potential is little exploited as compared to the economic value of the products that can be obtained. The estimation of conversion capacity of permanent grassland production in animal production has been made according to some studies based on the research in the field of grasslands, on areas similar to the ones in this county. At a medium level of production, its conversion in the meat production would lead to achieving an average increase of kg/ha, at the unfertilized grassland and of 125 kg/ha, at the fertilized grassland. The efficiency in milk production would amount to 1154 l/ha, at unfertilized grasslands and to 2500 l/ha at the fertilized ones.

    Full Text Available Currently, the concern with safe food and its quality has been achieving great growth worldwide. For those attributes to be secured, electronic identification is the first step to ensure animal products traceability. This research aimed to study invasive and non-invasive electronic identification methods, and the benefits and drawbacks of these mechanisms in meat productive chain, since 1983 to date. By means of this bibliographic survey, it was observed there are several tools available that may be useful to farmers to attain the electronic identification, and the advantages and disadvantages of each method should be considered to choose the best one for each situation. Invasive methods have been subject of many studies, which reflects the broad commercial use of these identifiers, however, issues related to animal welfare and specific disadvantages may restrict their use. Non-invasive methods are more aligned to the practices of animal welfare, but they are more expensive, less practical, and less studied than others.

    Full Text Available A participatory rural appraisal (PRA survey approach was used to identify the major constraints to agricultural production and to describe the major production systems in the sudano savanna and sudano sahelian zone of northern Cameroon. Relative emphasis was placed on the household level characterization to have a better understanding of the land use system, farmers' constraints to production and opportunities, so as to better target agricultural technologies and interventions in this vast agro-ecological zone. It was noted that, large variations exist in agriculture management practices between agro-ecological zones, among villages and households in terms of access to resources, such as labour, fertilizers, livestock, farm equipment, and land. Intensive and extensive farming practices might co-exist within the same village and households. The mains sources of vulnerability were identified. Results are used to set research priorities which will be directed towards the need of the majority of area's population; the improvement of sustainable food and feed crop production.

  16. The importance of urea-molasses blocks and bypass protein in animal production: The situation in tropical Latin America

    International Nuclear Information System (INIS)

    The grasslands of Latin America sustain 25% of the world cattle population. Most of the cattle are located in tropical Latin America. There are two predominant systems of production, dual purpose and beef, with diets based primarily on cultivated or native pastures and to a minor extent on conserved feeds and fibrous agricultural by-products. Urea-molasses blocks and bypass protein supplements are recently introduced technologies that could contribute to solution of some of the feeding constraints of the systems. The use of bypass protein has been mainly studied using fish meal as a supplement to medium quality basal feeds. Large live weight gain responses have been obtained with growing animals, but the influence on milk yield of dual purpose animals is small or non-existent. Supplements with fish meal offered once a day did not increase the utilization of basal fibrous diets in the rumen and were not able to sustain adequate levels of ammonia nitrogen throughout the day. Lower responses have been obtained with other bypass protein sources. The use of urea-molasses blocks has been investigated less. The major impact of this technology should be in extensive grazing systems with diets based on native pastures low in nitrogen. The scarce evidence available indicates that the sporadic consumption of blocks in these conditions prevents them from fulfilling the main objective, which is to provide a constant source of degradable nitrogen throughout the day. But there is still a positive effect on live weight change and reproduction during the dry season. The blocks should be adapted to this situation by incorporation of sources of slow nitrogen release.

  17. Techno-economic feasibility of animal feed production from empty fruit bunches

    International Nuclear Information System (INIS)

    It has been shown in our laboratory that EFB has the potential to be converted into animal feeds through the process of fermentation; and also use as media for mushroom growing (1). Irradiation of EFB at doses above 10 kGy followed by fermentation can reduce crude fibre (CF) content to almost 20-30% and crude protein (CP) content elevated to 10-15% from 50% and 2% respectively (2)(3). The end-product of fermentation displayed all the characteristics of animal feed, and at these levels of CF and CP can be utilised for feeding ruminants. Further reduction of CF and raising of CP can result in the products suitable for feeding non-ruminants such as poultry and pigs. Following the successful conversion of raw EFB into foodstuff for ruminant in the laboratory, there is an urgent need to evaluate whether such products could be mass-produced economically at larger scale for further feeding-trials. Pilot plant has to be set up to simulate the actual commercial production process before any technology transfer can be undertaken. The main objective of this paper is to report firstly, the economic and financial feasibility of the production process at pilot level. Secondly, preliminary evaluation on the cost of production of animal feed from EFB

    Full Text Available This study examined constraints militating against the profitability potentials of snail (Archachatina marginata production by small-scale snail farmers in Cross River State, Nigeria. Data were obtained from a random sample of 120 respondents in the study area by means of structured and semi-structured questionnaire. The first stage involved random selection of three (Ogoja, Ikom and Odukpani local government areas from eighteen local government areas in Cross River State, Nigeria. This was followed by random selection of three villages (Igoli in Ogoja Local Government Area, Alesi in Ikom Local Government Area and Adiabo in Odukpani Local Government Area in Cross River State. The respondents were randomly selected from each of the villages, 40 respondents were selected each from three villages, making a total number of 120 respondents. Data collected were analyzed using descriptive statistics and costs returns analysis. The results indicated that Cobb-Douglas production function had the best fit in explaining the relationship between output of snail and inputs used, the coefficient of multiple determinant (R2=0.60 indicates that sixty percent of the variability in output of snail is explained by the independent variables. Results from the analysis revealed that the marginal value products of farm size, labour, farm management practices and operating costs were N1080, N20.6, N972.8, N14.84 respectively, there existed allocative inefficiency, there is a high potential for snail farmers to increase their yields and income. Further analysis of results revealed that net returns on snail is N2,935,000.00 with return on every naira invested of N0.14 is also positive indicating a profit from the business, with attractive net return on investment. This study shows that snail farmers are faced with several problems in their production activities. These problems or constraints affect the efficiency of snail production in the study area.

    Full Text Available The paper aimed to approach the topic of a new strategy for the sustainable and competitive development of Romanian agriculture and especially for animal husbandry. In this purpose, a large variety of studies was investigated and the opinions of well-known personalities were used to present in a critical manner the history of sustainable development concept, principles, causes, reasons, moments, events, institutions involved at international, European and national level, achievements. The study is focused on Romania, starting from the actual situation of animal husbandry and learning from the country own and others experience. During the last centuries, the scientific studies noticed that the growth trends of the world population and resources utilization which could determine complications for survival of human society. The first Report of The Club of Rome (1972 concluded mathematically that " if the present growth trends in world population, industrialization, pollution, food production, and resources depletion continue to remain unchanged, the limits to growth on this planet will be reached sometime in the next hundred years",..that is in the 21 century. As a reply, the international and national bodies adopted recommendations for a sustainable development. This study analyzed the problems of sustainable development of animal production in Romania, taking into consideration that the conversion rate of energy provided by plants to animal products is about 20%, and this decrease of the number of population is supported by agricultural food production. Two production systems are proposed: (1. Intensive production systems, with high forage conversion, in favorable agricultural country area; (2. extensive (free-ranging, transhumance, pendulation, sustainable, biological production in not or less favorable agricultural area (mountain area, etc.

    Full Text Available In the current economic conditions of the import substitution, special importance is given to the search for new feed sources, methods of preparing them for feeding, the use of biologically active substances and enzymes. At the forefront of feed production is rape as breeding work with this culture has showed positive results. Currently, selectionists have bred yellow double-zero "00" varieties of rapeseeds free of erucic acid of "Canole" type, that have low glucosinolate level. The development of new and modern technology standards are required for preparation them for feeding, since they are fundamentally different from the previously used rapeseed varieties and have fewer restrictions for feeding to different types of farm animals and poultry. The article presents a fairly lengthy and reasoned review of the literature of a large number of authors on the topic, as well as given rapeseed market analysis, rational and advanced methods of preparing rapeseed processed products for feeding to young and adult animals. Much attention is paid to the use of a variety of biologically active substances and enzymes, which improve digestion and absorption of nutrients from rations with rapeseed processingproducts, increase productivity and reduce feed costs per unit of production. The use of processing products of rapeseed improves the profitability of livestock production. Feeding of rapeseedcake to cattle increases the protein content and volatile fatty acids in the rumen content, increases the number of infusoria and decreases ammonia levels. The inclusion of rape forage in diets of farm animals and poultry improves hematological parameters. Products of rapeseed processing of the varieties with low glucosinolatesa1re recommended for the rations of farm animals and poultry depending on the species, age and physiological state

  1. Influence of spatial variation on countermeasures with special regards to animal food products

    International Nuclear Information System (INIS)

    In the context of SAVE, soil and animal based countermeasures have been considered as well as human based ones: In this technical deliverable we have considered the following countermeasures: - Soil-plant transfer: The effectiveness of Ca, K, fertilisers and substances with a high cation exchange capacity on the transfer of radiocaesium from soil to plant for different soil types within Europe have been considered. In addition, the fertility status of soils will give an indication of the potential effectiveness of fertilisation. In this report the effect of K application in a specified area and a given contamination scenario is evaluated and demonstrated. - Plant-animal transfer: A wide range of countermeasures is available to directly reduce transfer of radionuclides to animals, and thereby animal products. The preferred option will always be the most cost effective and practically acceptable one, for both producers and consumers. In this report collection of animal based countermeasures for Cs, Sr and I with special respect to their acceptability, effectiveness and spatial variation is presented. The contribution and importance of countries in import and export of feedstuff used for animals is estimated based on trading information. (orig.)

  2. A fuzzy multi-regional input–output optimization model for biomass production and trade under resource and footprint constraints

    International Nuclear Information System (INIS)

    Interest in bioenergy in recent years has been stimulated by both energy security and climate change concerns. Fuels derived from agricultural crops offer the promise of reducing energy dependence for countries that have traditionally been dependent on imported energy. Nevertheless, it is evident that the potential for biomass production is heavily dependent on the availability of land and water resources. Furthermore, capacity expansion through land conversion is now known to incur a significant carbon debt that may offset any benefits in greenhouse gas reductions arising from the biofuel life cycle. Because of such constraints, there is increasing use of non-local biomass through regional trading. The main challenge in the analysis of such arrangements is that individual geographic regions have their own respective goals. This work presents a multi-region, fuzzy input–output optimization model that reflects production and consumption of bioenergy under land, water and carbon footprint constraints. To offset any local production deficits or surpluses, the model allows for trade to occur among different regions within a defined system; furthermore, importation of additional biofuel from external sources is also allowed. Two illustrative case studies are given to demonstrate the key features of the model.

    Full Text Available Due to more efficient use of feed, many farms, ensuring high productivity, has reached the profitability of milk production 40 % or more. No wonder milk has recently been called "white gold" because it provides the highest profitability among livestock products. However, higher producing cows have higher requirements for balanced feeding. Such cows are more intense metabolism: compared to cows of average productivity, the gas exchange is increased in 1,5-2 times, also increases blood pressure, pulse rate and respiration. This means that the wear and tear of the body is faster. And the consequences of inadequate feeding due to unbalanced diets on nutritional and biological active substances lead to profound metabolic disorders, which leads to disruption of the function of reproduction, diseases, shortening productive use of animals to one or two lactations. Without a system of introduction of achievements of zoo technical and veterinary Sciences, the proper organization of feeding, housing and care, application of progressive forms of work organization - cannot be opened, laid in the animals genetic potential. The main direction in the development of dairy cattle breeding is its intensification. The effectiveness of intensification is the implementation of the following development paths: full implementation and improvement of the genetic potential of dairy cattle; rich, biologically full feeding of animals; preparation of sufficient high-quality feed; implementation of efficient technologies.

  4. Hungry for success: Urban consumer demand for wild animal products in Vietnam

    2011-01-01

    Full Text Available Rising urban prosperity is escalating demand for wild animal products in Vietnam. Conservation interventions seek to influence consumer demand, but are based on a limited understanding of consumers and consumption behaviour. This report presents key findings of a structured survey (n=915 and semi-structured interviews (n=78 to investigate the social context of consumption of wild animal-derived products among the population of central Hanoi. Wildmeat is the product most commonly reported consumed-predominantly by successful, high-income, high-status males of all ages and educational levels-and is used as a medium to communicate prestige and obtain social leverage. As Vietnam′s economy grows and its population ages, demand for wildmeat and medicinal products is likely to rise. Given the difficulties of acting on personal rather than collective interests and the symbolic role of wildmeat in an extremely status-conscious society, reducing demand is challenging. Influencing consumer behaviour over the long term requires social marketing expertise and has to be informed by an in-depth understanding, achieved using appropriate methods, of the social drivers of consumer demand for wild animal products. In the meantime, strengthened enforcement is needed to prevent the demand being met from consumers prepared to pay the rising costs of finding the last individuals of a species.

    Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible polyesters considered as alternatives to petroleum-based plastics. Ralstonia eutropha is a model organism for PHA production. Utilizing industrially rendered waste animal fats as inexpensive carbon feedstocks for PHA production is demonstrated here. An emulsification strategy, without any mechanical or chemical pre-treatment, was developed to increase the bioavailability of solid, poorly-consumable fats. Wild type R. eutropha strain H16 produced 79-82% (w/w) polyhydroxybutyrate (PHB) per cell dry weight (CDW) when cultivated on various fats. A productivity of 0.3g PHB/(L × h) with a total PHB production of 24 g/L was achieved using tallow as carbon source. Using a recombinant strain of R. eutropha that produces poly(hydroxybutyrate-co-hydroxyhexanoate) [P(HB-co-HHx)], 49-72% (w/w) of PHA per CDW with a HHx content of 16-27 mol% were produced in shaking flask experiments. The recombinant strain was grown on waste animal fat of the lowest quality available at lab fermenter scale, resulting in 45 g/L CDW with 60% (w/w) PHA per CDW and a productivity of 0.4 g PHA/(L × h). The final HHx content of the polymer was 19 mol%. The use of low quality waste animal fats as an inexpensive carbon feedstock exhibits a high potential to accelerate the commercialization of PHAs.

    The aim of this study was to review the current legislation and rules in Brazil that involve quality assurance of animal products during food service reception. Published federal legislation and technical regulations were verified to present a broad general approach to raw material reception. Food service determinations included specifications of the criteria for evaluating and selecting suppliers, verifying the transport system, reception area requirements, and inspecting raw material. For product approval, the packaging, labeling, and temperature should be evaluated. However, periodic microbiological, physicochemical, and sensory support assessment analyses are not required for receiving animal products. For the safety of the raw material, it was concluded that the largest impacts came from the regulation and supervision of the food sector provider because of the challenges of food service and a lack of requirements to use more complex evaluation methods during the reception of raw materials.

    Intensive free-range pig production on open grasslands has disadvantages in that it creates nutrient hotspots and little opportunity for pigs to seek shelter from the sun. Combining a perennial energy crop and pig production might benefit the environment and animal welfare because perennial energy...... crops like willow (Salix sp.) and Miscanthus offer the pigs protection from the sun while reducing nutrient leaching from pig excrements due to their deep rooting system. The objectives of this study were to evaluate how season and stocking density of pigs in a free-range system with zones of willow...... production of pigs and energy crops is a feasible strategy to benefit both the environment and animal welfare....

    The objective of this paper is to review programs to improve production of animal source foods in Vietnam, emphasizing the VAC ecosystem and trends in undernutrition during past decades. The food consumption surveys of the Vietnamese population in 1985 showed that food intake was inadequate, especially animal protein. Most protein came from rice; the consumption of meats, beans and fish was negligible. During the last 10 y, much attention was paid to improving the health and nutritional status of the Vietnamese people. Many programs were implemented in Vietnam to improve the food intake and nutritional status of the people, and especially the intake of animal source foods. The VAC system is a traditional type of farming for Vietnamese people. The aim of VAC is to provide diversified agricultural products to meet the complex nutritional demands of man. Based on the scientific fundamentals of VAC, many different models of VAC have been developed at a national level. The intervention programs to improve production and consumption of animal source foods, and the VAC ecosystem in Vietnam during the last decade have been successful. The population's dietary intakes have clearly improved in terms of both quality and quantity. The consumption of staple foods in 2000, including meats, fish, fats and oils, and ripe fruits was much higher compared to 1987. The prevalence of undernutrition in children <5 y old, and of chronic energy deficiency (CED) in women of reproductive age, has been remarkably reduced.

    The objectives of this study were to estimate and evaluate potassium (K) and magnesium (Mg) budgets and flows of animal production in the basin of Dianchi Lake, China. Feed sampling and farmer interviews were conducted in field surveys. The supplies of K and Mg from local and external feeds and the retention, production and excretion of animals were calculated individually for dairy cows, fattening pigs, breeding sows, and broilers and laying hens. The K and Mg flows on a regional level were estimated using the individual budgets. At the individual level, in dairy cattle, the K and Mg supplied from local feeds accounted for large parts of the total nutrient intakes, whereas in the other animal categories most of the K and Mg in the feeds depended on external resources. Our findings also suggested that excessive Mg intake resulted in high Mg excretion and low use efficiency in dairy cattle and fattening pigs. At the regional level, the K and Mg amounts of manure produced and applied in the area (K: 339 and Mg: 143 t/year) exceeded those used as local feeds. Our results imply the animal production potentially increased the K and Mg loads in the regional agriculture system. PMID:26420449

    In 1947 the Medical Research Council of Britain established the Laboratory Animals Bureau in order to develop national standards of animal production that would enable commercial producers better to provide for the needs of laboratory animal users. Under the directorship of William Lane-Petter, the bureau expanded well beyond this remit, pioneering a new discipline of "laboratory animal science" and becoming internationally known as a producer of pathogenically and genetically standardized laboratory animals. The work of this organization, later renamed the Laboratory Animals Centre, and of Lane-Petter did much to systematize worldwide standards for laboratory animal production and provision--for example, by prompting the formation of the International Committee on Laboratory Animals. This essay reconstructs how the bureau became an internationally recognized center of expertise and argues that standardization discourses within science are inherently internationalizing. It traces the dynamic co-constitution of standard laboratory animals alongside that of the identities of the users, producers, and regulators of laboratory animals. This process is shown to have brought into being a transnational community with shared conceptual understandings and material practices grounded in the materiality of the laboratory animal, conceived as an instrumental technology.

The source of pesticide contamination in animal products is generally originated from feed materials, fodders . contaminated soils and water around the farm areas . Minimalization approach of pesticide residues in animal products could be conducted integratedly, such as through chemical process, biodegradation using microorganisms . Organic farming system is recognised as an alternative that may be applied to minimise contamination on agricultural land, eventually reducing pesticide residues in the agricultural products . Feeding with organic agricultural by-products with low pesticide residues appears to reduce pesticide residues in animal products . In order to eliminate pesticide contamination in soil, it has to be conducted progressively by implementing sustainable organic farming .

    Full Text Available A simulation study was conducted to estimate the production costs of animals with different proportions of Holstein genes and annual return per cow in a herd from the northern region of Minas Gerais. Data from the zootechnical archive of Fazenda Queluz, Francisco Sá, MG, Brazil, comprising the period from 2007 to 2012 were used. The production system consists of crossbred Holstein x Zebu (HZ cows with a genetic composition ranging from 1/4 HZ to 7/8 HZ. Total revenue per animal, annual profit per cow and variation in profitability were estimated over the years according to genetic composition. The revenue from milk production was greater for 7/8 HZ cows, but the estimated annual profit per cow was only 7.75% of total revenue, followed by 3/4 HZ cows which also exhibited low profit (4.11%. The highest profit was observed for 3/8 HZ cows, followed by 1/4 HZ and 1/2 HZ animals. Inversion of the genetic composition of the herd was observed over the years. In 2007, 64% of cows of the herd were 7/8 HZ, while in 2012, 7/8 HZ cows had been replaced with 1/4 HZ, 3/8 HZ and 1/2 HZ animals, accounting for 90% of all genotypes. Despite the greater production of animals with a higher proportion of Holstein genes, the change to cows with a higher proportion of genes of dairy Zebu breeds increased profitability, a fact that might be attributed to the greater economic efficiency of this genotype.

  15. FAO/IAEA international symposium on applications of gene-based technologies for improving animal production and health in developing countries. Book of extended synopses

    International Nuclear Information System (INIS)

    Genetic engineering is at the forefront of much biological research - basic, adaptive and applied or near market. Manipulation of genes to bring about the expression of a specific product, or to produce a characteristic or trait, offers exciting possibilities within both the plant and the animal kingdom. The opportunities, in terms of improving livestock productivity or reducing losses from disease, lie in a number of areas. In almost all areas of this research, isotopic markers are extensively used and are in most cases essential for achieving the levels of sensitivity required for genetic characterization and manipulation. Genetic engineering has the potential to solve many problems relating to animal productivity and health. At present the focus is on the problems that face livestock producers in the developed world. If the full benefit of this technology is to be realized globally, the problems confronting livestock farmers in developing countries will have to be considered. The characterization and application of methods in these regions has to be managed and exploited. It is hoped that this Symposium will stimulate the international exchange of information and ideas that contribute to greater accessibility and enhanced use of gene based technologies in animal agriculture in developing countries.

    The 360 feed and manure samples were collected from 150 animal farms in Jiangsu Province, China and analyzed for heavy metals. Concentrations of Zn and Cu in animal feeds were 15.9-2041.8 and undetected-392.1 mg/kg respectively, while Hg, As, Pb, Cd, and Cr in all feeds were below 10 mg/kg. Concentrations of Cu, Zn, and Cr in animal manures were 8.4-1726, 39.5-11379, and 1.0-1602 mg/kg respectively, while As, Cd, Hg, and Pb were animal feed and manure were positively correlated (p animal manure have been greatly increased over 18 years and the contribution of manures to soil should be considered.

  17. Cadmium in animal production and its potential hazard on Beijing and Fuxin farmlands

    International Nuclear Information System (INIS)

    A random sample of pairs of animal feeds and manures were collected from 215 animal barns in Beijing and Fuxin regions of China. The concentrations of Cd in manures and feeds ranged from non-detectable to 129.8 mg/kg dry weight and non-detectable to 31 mg/kg dry weight, respectively. The concentrations of Cd in pig, dairy cow and chicken manures were positively correlated to those in their feeds. About 30% of the manure samples contained Cd concentrations higher than the upper limit for use in farmlands, and pig and chicken manures might be the primary contributors of Cd to farmlands. The farmlands in Beijing and around the Fuxin Downtown areas would exceed the soil quality criteria within several decades according to current manure Cd loading rates. Undoubtedly, more scientific animal production and manure management practices to minimize soil pollution risks are necessary for the two regions.

    A two-step catalytic process for the production of biodiesel from waste frying oil (WFO) at low cost, utilizing waste animal-bone as catalyst and solar radiation as heat source is reported in this work. In the first step, the free fatty acids (FFA) in WFO were esterified with methanol by a catalytic process using calcined waste animal-bone as catalyst, which remains active even after 10 esterification runs. The trans-esterification step was catalyzed by NaOH through thermal activation process. Produced biodiesel fulfills all the international requirements for its utilization as a fuel. A probable reaction mechanism for the esterification process is proposed considering the presence of hydroxyapatite at the surface of calcined animal bones.

  1. The future trends for research on quality and safety of animal products

    Full Text Available Quality must now be considered as a convergence between consumers' wishes and needs and the intrinsic and extrinsic quality attributes of food products. The increasing number of quality attributes which must be considered, increasing globalisation and the heterogeneity in consumption habits between countries are making this convergence progressively more difficult. In parallel, science is rapidly evolving (with the advent of genomics for instance, and a growing number of applications is thus expected for the improvement of food safety and quality. Among the meat and fish quality attributes, colour is very important because it determines, at least in part, consumer choice. The key targets to ensure a satisfactory colour are animal nutrition and management for fish, processing and product conditioning for meat. Tenderness and flavour continue to be important issues for the consumer because eating remains a pleasure. They both determine quality experience which itself influences repetitive purchase. Meat tenderness is a very complex problem which can be solved only by a holistic approach involving all the factors from conception, animal breeding and production, muscle biology and slaughter practice to carcass processing and meat preparation at the consumer end. Today, safety and healthiness are among the most important issues. Unfortunately, animal products can potentially be a source of biological and chemical contamination for consumers. The introduction of both control strategies along the food chain and the development of a food safety management system, from primary production to the domestic environment, are key issues that must be achieved. Despite a high dietary supply of saturated fats by dairy and meat products, it is imperative that professionals involved in animal research and in the associated industry convey the positive nutritional contributions of animal products to both consumers and health professionals. The latter include protein

  2. A constraint on prompt supernova cosmic ray production from γ-ray observations

    International Nuclear Information System (INIS)

    The consequences of prompt cosmic ray production intrinsic to supernovae are examined for supernova explosions occurring in dense molecular clouds. For reasonable parameters it is shown that prompt cosmic ray production cannot exceed 1048 erg per supernova. This suggests that cosmic ray production takes place mainly in the intercloud medium.

    We study the practical production planning problem of a food producer facing a non-stationary erratic demand for a perishable product with a fixed life time. In meeting the uncertain demand, the food producer uses a FIFO issuing policy. The food producer aims at meeting a certain service level at lowest cost. Every production run a set-up cost is incurred. Moreover, the producer has to deal with unit production cost, unit holding cost and unit cost of waste. The production plan for a finite t...

    Full Text Available Information on livestock movement, animal food products processing facilities, meat inspection methods, official meat inspection records and distribution and marketing systems for processed products in Imo state, Nigeria needed for policy development interventions in the sector are not fully understood. The primary data generated with the aid of personal interviews, field observations and secondary data obtained from records accumulated by the department of veterinary services Imo state from 2001 to 2004 were used to investigate the environmental and public health issues of animal food products delivery system in state. Majority of trade animals supplied to the state originated from the northern states of the country and were brought in with trucks by road. Only two veterinary control posts served the whole state thus resulting in non-inspection and taxing of a large proportion of trade animals. Official record of trade animals supplied to the state from 2001 to 2004 ranged from 45000 – 144000 for cattle, 23000 – 96000 for goats and 11000 – 72000 for sheep per annum, with supplies increasing steadily across the years. Official slaughter points in the state were principally low-grade quality slaughter premises consisting of a thin concrete slab. Meat handling was very unhygienic with carcasses dressed beside refuse heaps of over 2 years standing. Carcasses were dragged on the ground and transported in taxi boots and open trucks. Meat inspection at these points was not thorough because of stiff resistance of butchers to carcass condemnation. Official meat inspection records for the state from 2001 to 2004 revealed that overall totals of 159,000 cattle, 101,000 goats and 67,000 sheep were slaughtered. This accounted for about 56, 57 and 57% shortfall of cattle, goat and sheep respectively supplied to the state and represents the volume of un-inspected animals during the study period. Fascioliasis and tuberculosis were the most common

    2015-06-01

    Full Text Available Irrespective of the existence of potentially pathogenic organisms carried by animals, foods of animal origin remain the prime nutrition of humans world-wide. As such, food safety continues to be a global concern primarily to safeguard public health and to promote international trade. Application of integrated risk-based quality assurance procedures on-farm and at slaughterhouses plays a crucial role in controlling hazards associated with foods of animal origin. In the present paper we examine safety assurance systems and associated value chains for foods of animal origin based on historical audit results of some Southern African countries with thriving export trade in animal products, mainly to identify areas for improvement. Among the key deficiencies identified were: i failure to keep pace with scientific advances related to the ever-changing food supply chain; ii lack of effective national and regional intervention strategies to curtail pathogen transmission and evolution, notably the zoonotic Shiga toxin-producing Escherichia coli; and iii a lack of effective methods to reduce contamination of foods of wildlife origin. The introduction of foods of wildlife origin for domestic consumption and export markets seriously compounds already existing conflicts in legislation governing food supply and safety. This analysis identifies gaps required to improve the safety of foods of wildlife origin.

    Full Text Available Abstract Background Although a variety of animals have been used to produce polyclonal antibodies against antigens, the production of antigen-specific monoclonal antibodies from animals remains challenging. Results We propose a simple and rapid strategy to produce monoclonal antibodies from a variety of animals. By staining lymph node cells with an antibody against immunoglobulin and a fluorescent dye specific for the endoplasmic reticulum, plasma/plasmablast cells were identified without using a series of antibodies against lineage markers. By using a fluorescently labeled antigen as a tag for a complementary cell surface immunoglobulin, antigen-specific plasma/plasmablast cells were sorted from the rest of the cell population by fluorescence-activated cell sorting. Amplification of cognate pairs of immunoglobulin heavy and light chain genes followed by DNA transfection into 293FT cells resulted in the highly efficient production of antigen-specific monoclonal antibodies from a variety of immunized animals. Conclusions Our technology eliminates the need for both cell propagation and screening processes, offering a significant advantage over hybridoma and display strategies.

    Changes in livestock production, driven by both demand- and supply-side factors, have been significant worldwide. Though historically the developed world was a large supplier of meat and livestock for the developing world, the developing world has rapidly increased production and is meeting more of its growing domestic demand. Many regions of the developing world, however, do not produce enough currently to meet their domestic demand and continue to import more than they produce. There are exceptions, such as Brazil, Thailand, the People's Republic of China and India, where growth in livestock production has been rapid. It is anticipated that in the future many of the developing countries will increase domestic production to meet growing domestic demand. By 2030, beef will probably still be the most significant meat import of developing countries and milk will have more than doubled as a net export of the developed world.

    Tandukar, Madan; Pavlostathis, Spyros G

    2015-12-15

    A bench-scale investigation was conducted to select external organic wastes and mixing ratios for co-digestion with municipal sludge at the F. Wayne Hill Water Resources Center (FWHWRC), Gwinnett County, GA, USA to support a combined heat and power (CHP) project. External wastes were chosen and used subject to two constraints: a) digester retention time no lower than 15 d; and b) total biogas (methane) production not to exceed a specific target level based on air permit constraints on CO2 emissions. Primary sludge (PS), thickened waste activated sludge (TWAS) and digested sludge collected at the FWHWRC, industrial liquid waste obtained from a chewing gum manufacturing plant (GW) and dewatered fat-oil-grease (FOG) were used. All sludge and waste samples were characterized and their ultimate digestibility was assessed at 35 °C. The ultimate COD to methane conversion of PS, TWAS, municipal sludge (PS + TWAS; 40:60 w/w TS basis), GW and FOG was 49.2, 35.2, 40.3, 72.7, and 81.1%, respectively. Co-digestion of municipal sludge with GW, FOG or both, was evaluated using four bench-scale, mesophilic (35 °C) digesters. Biogas production increased significantly and additional degradation of the municipal sludge between 1.1 and 30.7% was observed. Biogas and methane production was very close to the target levels necessary to close the energy deficit at the FWHWRC. Co-digestion resulted in an effluent quality similar to that of the control digester fed only with the municipal sludge, indicating that co-digestion had no adverse effects. Study results prove that high methane production is achievable with the addition of concentrated external organic wastes to municipal digesters, at acceptable higher digester organic loadings and lower retention times, allowing the effective implementation of CHP programs at municipal wastewater treatment plants, with significant cost savings.

    Full Text Available Cyanobacteria are a promising biological chassis for the synthesis of renewable fuels and chemical bulk commodities.Significant efforts have been devoted to improve the yields of cyanobacterial products. However, while the introduction and heterologous expression of product-forming pathways is often feasible, the interactions and incompatibilities of product synthesis with the host metabolism are still insufficiently understood.In this work, we investigate the stoichiometric properties and trade-offs that underlie cyanobacterial product formation using a computational reconstruction of cyanobacterial metabolism. First, we evaluate the synthesis requirements of a selection of cyanobacterial products of potential biotechnological interest. Second, the large-scale metabolic reconstruction allows us toperform in-silico experiments that mimic and predict the metabolic changes that must occur in the transition from a growth-only phenotype to a production-only phenotype. Applied to the synthesis of ethanol, ethylene, and propane, these in-silico transition experiments point to bottlenecks and potential modification targets in cyanobacterial metabolism.Our analysis reveals incompatibilities between biotechnological product synthesis and native host metabolism, such as shifts in ATP/NADPH demand and the requirement to reintegrate metabolic by-products. Similar strategies can be employed for a large class of cyanobacterial products to identify potential stoichiometric bottlenecks.

    2008-06-01

    A simple and rapid multiresidue method was developed for the determination of twelve quinolones (ciprofloxacin, danofloxacin, difloxacin, enrofloxacin, flumequine, marbofloxacin, nalidixic acid, norfloxacin, ofloxacin, orbifloxacin, oxolinic acid and sarafloxacin) in muscle, liver, chicken eggs, milk, prawn and rainbow trout. The quinolones were extracted from a sample with acetonitrile-water (95 : 5). A fifth part of the filtered extract was diluted with water to keep the acetonitrile ratio at ca. 60%, and passed through a C18 mini-column. The eluate was evaporated to dryness, and the residues were dissolved in methanol-water (30 : 70) for HPLC analysis. The quinolones were separated on a Inertsil ODS-3V column (4.6 mm i.d.x250 mm) with a gradient system of 0.1% phosphoric acid-acetonitrile as the mobile phase, with fluorescence detection.No interfering peak was found on the chromatograms of animal and fishery products, except for milk. The recoveries of the quinolones were over 60% from the animal and fishery products fortified at 0.1 microg/g, and the quantification limits of the quinolones were 0.005 microg/g. This proposed method was found to be effective and suitable for the screening of the quinolones in animal and fishery products.

  20. Improving the productivity of dairy cattle on smallholder farms in Mzuzu milk shed area in Malawi: Constraints and possible interventions

    International Nuclear Information System (INIS)

    A study was carried out in the Mzuzu milk shed area in Northern Malawi, to identify major constraints to dairy cattle production systems prevailing in the area (Phase I) and develop a sustainable feed supplementation intervention (Phase II) based on tree legume leaves of Sesbania sesban for increasing milk production. Phase I of the study revealed that the major constraint to increasing productivity was poor nutrition related to the fluctuating supply of quality and quantity of feed. Body weights of cows averaged 301 ± 81.3 kg and ranged from 189 to 550 kg whereas the body condition score (BCS, on 1-9 scale) averaged 5.73 ± 1.35 and ranged from 2.00 to 9.00. Average milk production was 6.1 ± 5 kg/d and ranged from 1.5 to 19.0 kg/d. Post-partum reproductive status varied considerably. Cows consumed 10.6 ± 6.2 kg/day of roughage and 2.96 ± 1.45 kg/day of concentrates. The quality of the feeds was moderate. Roughages contained 1.56 ± 0.12% N while concentrates contained 1.88 ± 0.04% N. Poor reproductive management and prevalence of internal parasites were also identified as constraints. The intervention (Phase II) based on supplementation with tree legume leaves of Sesbania sesban significantly (P <0.05) improved the performance of dairy cows. Cows supplemented with tree legume leaves showed significantly higher body weights (368 ± 65.5 vs 348.7 ± 59.2 kg) and BCS (6.3 ± 0.9 vs 5.3 ± 1) compared to their counterparts receiving a supplement according to the present management practice. Daily milk yields of cows on the experimental diet averaged 8.6 ± 3.2 kg whereas those on control diet averaged 5.4 ± 1.7 kg. Significant differences in milk yields between the two groups of cows could have been due to higher dry matter intake from the supplementary diet. Cows on experimental diet consumed 3.5 ± 1.2 kg of supplementary feed as compared to 2.2 ± 0.7 kg by cows on the control diet. (author)

    The potential for biodiesel production based on utilization of residual animal fat and fish in Norway is estimated. This is based on a study of the amounts of residual fat that is possible to recover from grease traps in Bergen. Additional data from Trondheim and Oslo facilitated up-scaling to estimating national potential for utilizing this residue stream for biodiesel production. This is supplemented with data on residues from slaughterhouses and poultry, as well as the fishing industry. The results indicate that Norway has the potential for producing large amounts of biodiesel from these residue sources. (author)

    Organic agriculture is perceived as being more sustainable than conventional agriculture. However, while there is a growing interest in, and market for, organic products, large-scale conversion to organic agriculture is not taking place. Even though conversion from conventional to organic dairy production is not especially difficult in theory,…

    The present study was funded by the Ministry of Agriculture, Fisheries and Food, its aim being to identify the technical barriers to the development of reduced-fat alternatives for bakery products. Using National Food Survey (Ministry of Agriculture, Fisheries and Food, 1998) statistics on dietary consumption within the home, biscuits, cakes and pastries were identified as contributing significant amounts of fat to the population's dietary intake. Face-to-face interviews were conducted with contacts in the technical community of the baking industry, who were usually working in technical and new-product development functions. A discussion guide was developed to cover the main lines of enquiry. The companies selected were ingredient suppliers (eight), manufacturers (twelve) and retailers (four) and so represented each step of the food supply chain. In brief, results showed that current labelling rules were too stringent, and constrained development of reduced-fat bakery products. Products with lower fat levels are harder to make due to altered handling and processing properties. Their quality is usually poorer than standard products, particularly for flavour, texture and mouthfeel. The perception of freshness is reduced and product shelf-life may consequently be shorter. For the product developer, there are relatively few ingredients that can be used in place of fat, and knowledge of how they work is limited, which inhibits product development. There is no identifiable source of technical knowledge in this field. Consumers perceive reduced-fat bakery products to be of lower quality and are generally unwilling to pay higher prices than for standard products.

    2013-12-01

    This study used a stochastic bioeconomic simulation model to simulate the business and financial risk of different broiler production systems over a 5-yr period. Simulation analysis was conducted using the @Risk add-in in MS Excel. To compare the impact of different production systems on economic feasibility, 2 cases were considered. The first case focused on the economic feasibility of a completely new system, whereas the second examined economic feasibilities when a farm switches from a conventional to an animal welfare-improving production system. A sensitivity analysis was conducted to assess the key drivers of economic feasibility and to reveal systematic differences across production systems. The study shows that economic feasibility of systems with improved animal welfare predominantly depends on the price that farmers receive. Moreover, the study demonstrates the importance of the level and variation of the price premium for improved welfare, particularly in the first 5 yr after conversion. The economic feasibility of the production system increases with the level of welfare improvements for a sufficiently high price level for broiler meat and low volatility in producer prices. If this is not the case, however, risk attitudes of farmers become important as well as the use of potential risk management instruments.

    Immunisation by administration of antibodies (immunoglobulins) has been known for more than one hundred years as a very efficient means of obtaining immediate, short-lived protection against infection and/or against the disease-causing effects of toxins from microbial pathogens and from other sources. Thus, due to its rapid action, passive immunisation is often used to treat disease caused by infection and/or toxin exposure. However immunoglobulins may also be administered prior to exposure to infection and/or toxin, although they will not provide long-lasting protection as is seen with active immunisation (vaccination) in which an immunological memory is established by controlled exposure of the host to the pathogen in question. With multi-factorial infectious diseases in production animals, especially those that have proven hard to control by vaccination, the potential of passive immunisation remains big. This review highlights a number of examples on the use of passive immunisation for the control of infectious disease in the modern production of a range of animals, including pigs, cattle, sheep, goat, poultry and fish. Special emphasis is given on the enablement of passive immunisation strategies in these production systems through low cost and ease of use as well as on the sources, composition and purity of immunoglobulin preparations used and their benefits as compared to current measures, including vaccination (also comprising maternal vaccination), antibiotics and feed additives such as spray-dried plasma. It is concluded that provided highly efficient, relatively low-price immunoglobulin products are available, passive immunisation has a clear role in the modern animal production sector as a means of controlling infectious diseases, importantly with a very low risk of causing development of bacterial resistance, thus constituting a real and widely applicable alternative to antibiotics.

    Full Text Available The optimum mesophilic temperature of biogas production from blends The optimum temperature of biogas production from blends of animal-based wastes was determined under controlled heat supply to the digester in a batch digestion process. Cow Dung (CD and Poultry Droppings (PD were blended in the ratio of CD: PD: 1:3. The digester was operated at average ambient temperature of 30°C as baseline. Biogas production from the waste blends was monitored under the temperatures of 32 to 45°C. Results obtained indicate maximum cumulative gas yield was observed at the temperature of 40°C. The 40°C temperature gave the highest biogas yield of 2685 mL followed by the 35°C temperature with the cumulative yield of 2535 mL. The ambient temperature of 30°C had the least cumulative biogas yield of 185 mL. These results indicate that increased and steady biogas production can be achieved under the optimum mesophilic temperature of 40°C when these animal-based wastes are digested in batch digestion process.

    Full Text Available This paper studies a closed-loop supply chain network equilibrium problem in multiperiod planning horizons with consideration of product lifetime and carbon emission constraints. The closed-loop supply chain network consists of suppliers tier, manufacturer tier, retailers tier, and demand markets tier, in which the manufacturers collect used products from the demand markets directly. Product lifetime is introduced to denote the maximum times of manufacturing and remanufacturing, and the relation between adjacent periods is described by inventory transfer. By variational inequalities and complementary theory, the optimal behaviors of all the players are modeled, and, in turn, the governing closed-loop supply chain network equilibrium model is established. The model is solved by modified project contraction algorithm with fixed step. Optimal equilibrium results are computed and analyzed through numerical examples. The impacts of collection rate, remanufacturing conversion rate, product lifetime, and carbon emission cap on equilibrium states are analyzed. Finally, several managerial insights are given to provide decision support for entrepreneurs and government official along with some inspirations for future research.

    Coexistence of temperature constraint and continuous production constraint in scheduling areas in process industry, such as steelmaking and continuous casting brought great difficulty in production scheduling. Aiming at shortcomings of current work, a simulation scheduling method which combined scheduling and simulation was presented. Rapid and dynamic scheduling was achieved by avoiding repeated and blind scheduling and simulation. Scheduling models oriented to temperature constraint and continuous production constraint were set up. On this basis, intelligent simulation scheduling method by combining Agent technique with simulation was adopted to realize parallel processing of scheduling and constraint verification. The effectiveness of the proposed method was also verified by example.%炼钢等流程工业生产中的温度约束和连续生产约束同时存在时会给生产调度带来很大困难.针对现有工作的不足,提出了调度与仿真相结合的仿真调度方法,通过避免盲目的反复调度和仿真,达到快速动态调度的目的.该方法首先对温度约束和连续生产约束建立了约束调度模型;在此基础上,采用Agent技术与仿真结合的智能仿真调度的方法来实现调度和约束验证的并行处理.通过实例验证了该方法的有效性.

    Full Text Available The shea tree is a multipurpose tree crop indigenous to Sub Saharan African. The tree is highly cherished for the oil that is extracted from its kernels and used nationally and internationally in cosmetics, pharmaceutics and in chocolate formulations. The processing and sales represent significant income earning opportunities for rural women who are the main stakeholders in the production chain. Shea nuts and its products are listed among the top ten Non-Traditional Exports of Ghana. In Burkina Faso it is the fourth most important export crop after gold, cotton and livestock and makes a contribution of about 6 million USD to the national economy. Today the shea tree is the second most important oil crop in Africa after the palm nut tree. About 500 million shea trees grow in Africa which has the potential of producing shea nuts worth about 150 million USD yearly. This represents substantial earnings for the Sub-Saharan African economies when fully exploited. Shea trees grow in 21 Sub-Saharan African countries that can be grouped into 3 zones following their potentials for shea nut production per year: high production zone comprising of Benin, Burkina Faso, Cote D’Ivoire Ghana, Mali, Nigeria, Sudan and Uganda that have potentials of producing 70 000–300 000 tons per year; average production zone comprising of Cameroon, Chad, Central African Republic, Guinea Conakry, Senegal and Togo with potentials of 10 000–70 000 tons per year and low production zones made up of the Democratic Republic of Congo, Ethiopia, Gambia, Guinea Bissau, Niger and Sierra Leone with yearly production potentials less than 10 000 metric tons. Though semi mechanized and some few fully mechanized productions methods are employed in the major shea producing countries of West Africa, most of the rural women still used traditional processing procedures. Major importers of shea are European Union, Japan and the USA. The sector is still constrained by lack of

    At very-high energies (100 TeV - 1 PeV), the small value of Bjorken-x ($\\le10^{-3}-10^{-7}$) at which the parton distribution functions are evaluated makes the calculation of charm quark production very difficult. The charm quark has mass ($\\sim$1.5$\\pm$0.2 GeV) significantly above the $\\Lambda$$_{QCD}$ scale ($\\sim$200 MeV), and therefore its production is perturbatively calculable. However, the uncertainty in the data and the calculations cannot exclude some smaller non-perturbative contribution. To evaluate the prompt neutrino flux, one needs to know the charm production cross-section in pN -> c$\\bar{c}$ X, and hadronization of charm particles. This contribution briefly discusses computation of prompt neutrino flux and presents the strongest limit on prompt neutrino flux from IceCube.

The eruption has caused destruction of land and water resources, plants, death of animals and human casualities. The lava, dust and stones released from the eruption of Merapi had caused residential destruction, casualities, agricultural land and plants destruction, and contamination of water. The eruption has directly affected 4 districts including Sleman (Yogyakarta, Magelang, Boyolali and Klaten (Central Java categorized as Disaster Risk Area (DRA. The purpose of this assessment is to analyse the impacts of Merapi eruption in animal health and productivity in particular for dairy and beef cattle. A total of 2.828 heads of cattle was reported died during the eruption of Merapi, and 1.962 heads died at the time of eruption and 36 heads at the arrival on evacuation areas. Animal that found died including 423 heads of beef cattle (0.13% and 2.405 heads of dairy cattle (3.2%. Clinical sains noted after the eruption were reduction of milk production, loss of appetite, diarrhoea, respiratory disturbances, mastitis and collapse. The main problems for livestock were reduction of milk production, collapse of dairy milk corporation activities and contamination of water resources. Other than dairy cattle mortality, the reduction of milk production may be caused by subclinical mastitis and environmental distress due to temperature and noise of eruption for few days. The subclinical mastitis should be further investigated to establish rehabilitation programme for dairy milk agribussiness activity in particular around the DRA of Merapi.

    2016-09-01

    As bacteria and diseases spread due to climatic change, greater amounts of antibiotics will be used thereby exacerbating the problem of antibiotic resistance. To help slacken the development of resistant bacteria, the medical community is attempting to reduce unnecessary and excessive usage of antibiotics. One of the targets is the use of antibiotics for enhancing animal growth and promoting feed efficiency in the production of food animals. While governments can adopt regulations prohibiting nontherapeutic uses of antibiotics in food animals and strategies to reduce antibiotic usage, another idea is to publicize when antibiotics are used in food animal production by allowing labeled meat products. This paper builds upon existing labeling and marketing efforts in the United States to show how a government can develop a verified antibiotic-free labeling program that would allow consumers to purchase meat products from animals that had never received antibiotics.

    In livestock production, lactic acid bacteria (LAB) are the most common microorganisms used as probiotics. For such use, these bacteria must be correctly identified and characterized to ensure their safety and efficiency. In the present study, LAB were isolated from broiler excreta, where a fermentation process was used. Nine among sixteen isolates were identified by biochemical and molecular (sequencing of the 16S rRNA gene) methods as Lactobacillus crispatus (n=1), Lactobacillus pentosus (n=1), Weissella cibaria (n=1), Pediococcus pentosaceus (n=2) and Enterococcus hirae (n=4). Subsequently, these bacteria were characterized for their growth capabilities, lactic acid production, acidic pH and bile salts tolerance, cell surface hydrophobicity, antimicrobial susceptibility and antagonistic activity. Lactobacillus pentosus strain LB-31, which showed the best characteristics, was selected for further analysis. This strain was administered to broilers and showed the ability of modulating the immune response and producing beneficial effects on morpho-physiological, productive and health indicators of the animals.

  10. Genetic opportunities to enhance sustainability of pork production in developing countries: A model for food animals

    International Nuclear Information System (INIS)

    Currently there is a shortage of food and potable water in many developing countries. Superimposed upon this critical situation, because of the increasing urban wealth in these countries, there is a strong trend of increased consumption of meat, and pork in particular. The consequence of this trend will be increased agricultural pollution, resulting not only from greater use of chemical fertilizer, but also from manure spread on land as fertilizer that may enter freshwater and marine ecosystems causing extensive eutrophication and decreased water quality. The application of transgenic technologies to improve the digestive efficiency and survival of food animals, and simultaneously decreasing their environmental impact is seen as an opportunity to enhance sustainability of animal agriculture without continued capital inputs. Transgenes expressed in pigs that have potential include, for example, genes coding for phytase, lactalbumin and lactoferrin. At the University of Guelph, Escherichia coli phytase has been expressed in the salivary glands of the pig. Selected lines of these pigs utilize plant phytate phosphorus efficiently as a source of phosphorus and excrete faecal material with more than a 60 percent reduction in phosphorus content. Because of their capacity to utilize plant phytate phosphorus and to produce less polluting manure they have a valuable trait that will contribute to enhanced sustainability of pork production in developing countries, where there is less access to either high quality phosphate supplement or phytase enzyme to include in the diet. Issues that require continued consideration as a prelude to the introduction of transgenic animals into developing countries include food and environmental safety, and consumer acceptance of meat products from genetically modified animals.

    2008-07-01

    Among the factors used to analyze and to establish the sustainability of a whole agricultural production system, the energy balance is one of the most powerful and robust. The maize production in Brazil is surely the reflex of an energy intensive system that demands many field operations and heavy fertilizer applications, notably nitrogen in urea form. This work presents an energy balance of this major crop adjusted to the Brazilian conditions of cultivation. The input components were grouped based on their energy contents, and the possible improvements in the agricultural practices that could improve energy balance and net energy withdrawn from the farming were considered. The replacement of N synthetic fertilizer by biological nitrogen fixation, whether the process is directly carried out by endophytic diazotroph bacteria or by means of a N{sub 2}- fixing legume culture planted before the main crop as a green-manure is also discussed.

    In the open field, the environment is a critical determinant of crop yield and produce quality and it affects the geographical distribution of most crop species. In contrast, in protected cultivation, environmental control allows the fulfillment of the actual needs depending on the technological level. The economic optimum, however, depends on the trade-off between the costs of increased greenhouse control and increase in return, dictated by yield quantity, yield quality and production timing...

    Full Text Available Public concern for a healthy diet led to significant changes in the approach to food composition and nutritional principles by specialists in nutrition processed foods. In recent years researches in the meat industry were aimed at replacing animal fats with vegetable fats (oils, rich in essential fatty acids mono-and polyunsaturated. It was found that the existence of equilibrium in the human diet is some correlations between macronutrients and biologically active substances in food, which ensures the normal functioning of the body. In these experiment we observed how it was affected the sensory quality of compositions of chicken mincemeat in which the fat was gradually replaced by vegetable oil, sunflower oil, canola oil and walnut oil. In parallel the color parameters (CIELAB method of the low fat meat compositions were analyzed to determine how the animal fat replacement procedure affects the color of chicken minced. Sensory acceptability of the products was medium for the compositions in which the replacement of fat with oils was up to 60%, the best results being recorded for sunflower oil. The brightness value initially increased, but color parameters decreased, and acceptability of products decreased with increasing of oil amount. The correlation between the two types of measurements led to clear conclusions regarding the consumers’ acceptability of these products, obtained by adding varying amounts of oils.

    2016-01-01

    We examine the constraints on the trilinear Higgs coupling $\\lambda$ that originate from associated ($Vh$) and vector boson fusion (VBF) Higgs production in $pp$ collisions in the context of the Standard Model effective field theory. The 1-loop contributions to $pp \\to V h$ and $pp \\to jj h$ that stem from insertions of the dimension-6 operator $O_6 = - \\lambda \\left (H^\\dagger H \\right )^3$ are calculated and combined with the ${\\cal O} (\\lambda)$ corrections to the partial decay widths of the Higgs boson. Employing next-to-next-to-leading order QCD predictions, we analyse the sensitivity of current and forthcoming measurements of the signal strengths in $Vh$ and VBF Higgs production to changes in $\\lambda$. We show that future LHC runs may be able to probe modifications of $\\lambda$ with a sensitivity similar to the one that is expected to arise from determinations of double-Higgs production. The sensitivity of differential $Vh$ and VBF Higgs distributions to a modified $h^3$ coupling is also studied.

  15. Legality Constraints: The Emergence of a Dual Market for Tropical Timber Products?

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available The European Union (EU, the United States of America (USA, and Australia have adopted specific measures to avoid the placing of illegal timber on their markets. These measures might encourage the diversion of timber products from traditional large importers to destinations with a less stringent regulatory framework. During 2001–2013, the international trade in tropical primary timber products (logs; sawnwood; veneers and plywood decreased by 13% in volume and increased by almost 5% in value. Imports by Australia, the EU, and the USA halved, while those by emerging economies such as China and India initially remained stable and later increased. Tropical timber products—mostly logs and sawnwood—might have been diverted towards emerging economies over the period considered. This general trend is confirmed when analyzing imports from countries that are implementing voluntary partnership agreements (VPA within the EU Forest Law Enforcement, Governance and Trade (FLEGT Action Plan. Several factors might influence these market dynamics, including changes induced by the 2008 financial crisis and the increasing domestic demand for timber products by emerging nations. The effects of legality measures on market trends are still unclear. Nonetheless, they might have encouraged uncertainty with regards to traditional importers and favored emerging ones.

    Since the beginning of the large-scale commercial cultivation of genetically modified (GM) crops in the mid-nineties, it has continuously increased. This has occurred in particular in non-European countries from which these crops may be exported as commodities to Europe and other markets. Before genetically modified organisms (GMO) are allowed onto the market as animal feed and/or food, they have to undergo a regulatory safety assessment as required by the law in many nations, including that ...

  18. Diet authentication in sheep from the composition of animal tissues and products

    2009-07-01

    Full Text Available There is currently an increased consumer demand for information on herbivore production factors, particularly animal diet. To meet these demands, producers and commercial entities develop specifications via quality certifications. There is therefore a need for analytical tools that may guarantee that the specification commitments have been fully met or to help with constructing them. The present paper reviews the current state of knowledge concerning diet authentication in sheep meat and milk, the different approaches that have been investigated, some leading examples concerning the discrimination of contrasting feeding situations, together with the persistence of some diet markers in the event of changes in animals' diet. The nature of the diet strongly influences the composition of the animal tissues and products, which is due to specific compounds that are directly transferred from the feed to the end product or that are transformed or produced by rumen micro-organisms or the animal's metabolism under the effect of specific diets. Some of these compounds can therefore be used as diet markers. Compounds such as carotenoids, phenolic compounds, fatty acids, volatile compounds and ratios of oxygen, hydrogen, carbon and nitrogen stable isotope are potential tracers in meat and milk or animal tissues of animal feeding diets. Moreover, differences in meat and milk composition induce differences in their optical properties, and therefore in their spectral features, which can also be used for diet authentication. These techniques have already allowed discrimination among products obtained in contrasting feeding conditions. Intermediate situations, for example in case of modification of the animal's diet, may be less easily recognized and may require a combination of tracing methods. In particular, the persistence of tracers when animals are stall-fed a concentrate-based diet after pasture and its implications for traceability are discussed. Finally

  19. Production of keV Sterile Neutrinos in Supernovae: New Constraints and Gamma Ray Observables

    CERN Document Server

    Argüelles, Carlos A; Kopp, Joachim

    2016-01-01

    We study the production of sterile neutrinos in supernovae, focusing in particular on the keV--MeV mass range, which is the most interesting range if sterile neutrinos are to account for the dark matter in the Universe. We argue that in this mass range, the production of sterile neutrinos can be strongly enhanced by a Mikheyev--Smirnov--Wolfenstein (MSW) resonance, so that a substantial flux is expected to emerge from a supernova, even if vacuum mixing angles between active and sterile neutrinos are tiny. Using energetics arguments, this yields limits on the sterile neutrino parameter space that reach down to mixing angles on the order of $\\sin^2 2\\theta \\lesssim 10^{-14}$ and are up to several orders of magnitude stronger than those from X-ray observations. We also compute the flux of $\\mathcal{O}(\\text{MeV})$ photons expected from the decay of sterile neutrinos produced in supernovae, but find that it is beyond current observational reach even for a nearby supernova.

    The proposed Safe Cosmetics and Personal Care Products Act of 2013 calls for a new evaluation program for cosmetic ingredients in the US, with the new assessments initially dependent on expanded animal testing. This paper considers possible testing scenarios under the proposed Act and estimates the number of test animals and cost under each scenario. It focuses on the impact for the first 10 years of testing, the period of greatest impact on animals and costs. The analysis suggests the first ...

  1. Crisis management and recovery from the damage to the laboratory animal production facility due to the Great East Japan Earthquake.

    Charles River Laboratories Japan produces laboratory animals, mainly mice and rats. In its history, we have experienced many crises such as mass food poisoning of staff and contamination of animals. However, we overcame these crises, accomplishing our corporate missions to secure steady supply of healthy animals. Under such circumstances, in 2008, we faced an unprecedented crisis involving a novel influenza possibly becoming pandemic. Therefore, we prepared a Crisis Management Plan (CMP) and Business Continuity Plan (BCP) to avoid the worst case scenario. Fortunately, the novel influenza did not develop into a pandemic and no major problems occurred in production of our laboratory animals. In March 2011, our Tsukuba Breeding Center was struck by the Great East Japan Earthquake. Many cages fell from racks, and consequently, 14,000 mice and rats were euthanized. Moreover, this animal production facility experienced not only blackouts and water outage but also various maintenance problems. After triage of the animals, almost half of the animals kept were eventually lost. However, we recovered and resumed shipment of animals two weeks after the disaster by utilizing the CMP and BCP we initially created as a countermeasure against novel influenza. After two months, our production volume returned to normal except for two strains. I sincerely hope this review, which highlights our experience and related issues, will be a useful resource in regard to crisis management for people who are engaged in laboratory animal care and use.

  2. Constraints and opportunities for sustainable crop production in rainfed areas of pothwar plateau

    International Nuclear Information System (INIS)

    The rainfed areas, commonly known as barani tract, accounts for about 25% of the total cropped area in the Punjab. The Pothwar plateau comprising 1.82 million hectare, is the largest contiguous block of rainfed areas in Punjab. Low and erratic rainfall, water-erosion hazard, inadequate depth of soil and poor soil-fertility are the main limitations affecting the production-potential of these areas. To ensure that farmers readily adopt the agricultural technologies developed by the research-system, these should be based on real-life problems, appropriate to the natural and socio-economic environments in which farmers make decisions. The present study was undertaken in tehsils Fatehjang and Gujar Khan of Pothwar plateau, to broadly understand farmers perceptions and approaches for rainwater-harvesting and soil-fertility management. It was observed that farm size was relatively bigger in Fatehjang than Gujar Khan. About 86% and 63% of respondents in Gujar Khan and Fatehjang cultivated their own lands. Nearly 40% of respondents in both the tehsils had their lands in 3 to 6 parcels, which hindered the farm-operation and soil and water conservation activities. The uses of fertilizers are sub-optimal and imbalanced. The soil-fertility is going down. The rainwater-conservation practices are not being adopted, due to high cost of machinery and disinterest of farmers in agriculture. The farming is going to be come un- economical. The analysis of strengths, weaknesses, opportunities and threats (SWOT) was carried out and the results are discussed. Some recommendations have been proposed to control soil-erosion, moisture-stress and fertility-degradation and to sustain agricultural production in these areas. (author)

    In developing countries, biogas energy production is seen as a technology that can provide clean energy in poor regions and reduce pollution caused by animal manure. Laboratories in these countries have little access to advanced gas measuring equipment, which may limit research aimed at improving local adapted biogas production. They may also be unable to produce valid estimates of an international standard that can be used for articles published in international peer-reviewed science journals. This study tested and validated methods for measuring total biogas and methane (CH4) production using batch fermentation and for characterizing the biomass. The biochemical methane potential (BMP) (CH4 NL kg−1 VS) of pig manure, cow manure and cellulose determined with the Moller and VDI methods was not significantly different in this test (p>0.05). The biodegradability using a ratio of BMP and theoretical BMP (TBMP) was slightly higher using the Hansen method, but differences were not significant. Degradation rate assessed by methane formation rate showed wide variation within the batch method tested. The first-order kinetics constant k for the cumulative methane production curve was highest when two animal manures were fermented using the VDI 4630 method, indicating that this method was able to reach steady conditions in a shorter time, reducing fermentation duration. In precision tests, the repeatability of the relative standard deviation (RSDr) for all batch methods was very low (4.8 to 8.1%), while the reproducibility of the relative standard deviation (RSDR) varied widely, from 7.3 to 19.8%. In determination of biomethane concentration, the values obtained using the liquid replacement method (LRM) were comparable to those obtained using gas chromatography (GC). This indicates that the LRM method could be used to determine biomethane concentration in biogas in laboratories with limited access to GC. PMID:25049861

    Biological research of Sus scrofa, the domestic pig, is of immediate relevance for food production sciences, and for developing pig as a model organism for human biomedical research. Publicly available data repositories play a fundamental role for all biological sciences, and protein data repositories are in particular essential for the successful development of new proteomic methods. Cumulative proteome data repositories, including the PeptideAtlas, provide the means for targeted proteomics, system-wide observations, and cross-species observational studies, but pigs have so far been underrepresented in existing repositories. We here present a significantly improved build of the Pig PeptideAtlas, which includes pig proteome data from 25 tissues and three body fluid types mapped to 7139 canonical proteins. The content of the Pig PeptideAtlas reflects actively ongoing research within the veterinary proteomics domain, and this article demonstrates how the expression of isoform-unique peptides can be observed across distinct tissues and body fluids. The Pig PeptideAtlas is a unique resource for use in animal proteome research, particularly biomarker discovery and for preliminary design of SRM assays, which are equally important for progress in research that supports farm animal production and veterinary health, as for developing pig models with relevance to human health research.

    Full Text Available Abstract Background Animal-free recombinant proteins provide a safe and effective alternative to tissue or serum-derived products for both therapeutic and biomanufacturing applications. While recombinant insulin and albumin already exist to replace their human counterparts in cell culture media, until recently there has been no equivalent for serum transferrin. Results The first microbial system for the high-level secretion of a recombinant transferrin (rTf has been developed from Saccharomyces cerevisiae strains originally engineered for the commercial production of recombinant human albumin (Novozymes' Recombumin® USP-NF and albumin fusion proteins (Novozymes' albufuse®. A full-length non-N-linked glycosylated rTf was secreted at levels around ten-fold higher than from commonly used laboratory strains. Modification of the yeast 2 μm-based expression vector to allow overexpression of the ER chaperone, protein disulphide isomerase, further increased the secretion of rTf approximately twelve-fold in high cell density fermentation. The rTf produced was functionally equivalent to plasma-derived transferrin. Conclusions A Saccharomyces cerevisiae expression system has enabled the cGMP manufacture of an animal-free rTf for industrial cell culture application without the risk of prion and viral contamination, and provides a high-quality platform for the development of transferrin-based therapeutics.

    This study was conducted to determine the residual amount of veterinary drugs such as meloxicam, flunixin, and tulathromycin in animal products (beef, pork, horsemeat, and milk). Veterinary drugs have been widely used in the rearing of livestock to prevent and treat diseases. A total of 152 samples were purchased from markets located in major Korean cities (Seoul, Busan, Incheon, Daegu, Daejeon, Gwangju, Ulsan and Jeju), including Jeju. Veterinary drugs were analyzed by liquid chromatography-tandem mass spectrometry according to the Korean Food Standards Code. The resulting data, which are located within 70-120% of recovery range and less than 20% of relative standard deviations, are in compliance with the criteria of CODEX. A total of five veterinary drugs were detected in 152 samples, giving a detection rate of approximately 3.3%; and no food source violated the guideline values. Our result indicated that most of the veterinary drug residues in animal products were below the maximum residue limits specified in Korea. PMID:27433102

    Constraints are presented on the total width of the recently discovered Higgs boson, Gamma_H, using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron or muon pair, and the other to an electron, muon, or neutrino pair. The analysis is based on the data collected by the CMS experiment at the LHC in 2011 and 2012, corresponding to integrated luminosities of 5.1 inverse-femtobarns at a centre-of-mass energy $\\sqrt{s}$ = 7 TeV and 19.7 inverse-femtobarns at $\\sqrt{s}$ = 8 TeV. A simultaneous maximum likelihood fit to the measured kinematic distributions near the resonance peak and above the Z-boson pair production threshold leads to an upper limit on the Higgs boson width of $\\Gamma_H$ less than 22 MeV at a 95% confidence level, which is 5.4 times the expected value in the standard model at the measured mass.

    Full Text Available Constraints are presented on the total width of the recently discovered Higgs boson, ΓH, using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron or muon pair, and the other to an electron, muon, or neutrino pair. The analysis is based on the data collected by the CMS experiment at the LHC in 2011 and 2012, corresponding to integrated luminosities of 5.1 fb−1 at a center-of-mass energy s=7 TeV and 19.7 fb−1 at s=8 TeV. A simultaneous maximum likelihood fit to the measured kinematic distributions near the resonance peak and above the Z-boson pair production threshold leads to an upper limit on the Higgs boson width of ΓH<22 MeV at a 95% confidence level, which is 5.4 times the expected value in the standard model at the measured mass of mH=125.6 GeV.

    We compare ensembles of water supply and demand projections from 10 global hydrological models and six global gridded crop models. These are produced as part of the Inter-Sectoral Impacts Model Intercomparison Project, with coordination from the Agricultural Model Intercomparison and Improvement Project, and driven by outputs of general circulation models run under representative concentration pathway 8.5 as part of the Fifth Coupled Model Intercomparison Project. Models project that direct climate impacts to maize, soybean, wheat, and rice involve losses of 400-1,400 Pcal (8-24% of present-day total) when CO2 fertilization effects are accounted for or 1,400-2,600 Pcal (24-43%) otherwise. Freshwater limitations in some irrigated regions (western United States; China; and West, South, and Central Asia) could necessitate the reversion of 20-60 Mha of cropland from irrigated to rainfed management by end-of-century, and a further loss of 600-2,900 Pcal of food production. In other regions (northern/eastern United States, parts of South America, much of Europe, and South East Asia) surplus water supply could in principle support a net increase in irrigation, although substantial investments in irrigation infrastructure would be required.

    2014-01-01

    Full Text Available The recent surge in the use of biodiesel in Brazil and abroad, coupled with the availability of large amounts of glycerol, are generating interest in the use of this co-product in several ways, such as its use in animal feed. The use of glycerol in the formulation of diets caused immediate interest to obtain a highly efficient energy rich product to use in animal production. The aim of this study was to evaluate the effects of the use of glycerol resulting from biodiesel production as an energy supplement in animal feed, as well as establishing appropriate protocols for each species based on previous studies. Most of them using pigs, cows, bulls, sheep, laying hens and broilers. It was possible to infer from these studies that glycerol was a food ingredient suitable for replacement in diets of different animal species.

    Estimates of US anthropogenic greenhouse gas emissions by USEPA (Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2009; 2011) indicate that wastewater treatment plants are the 7th highest contributor to atmospheric nitrous oxide. This unregulated gas has an estimated global warming potential (GWP) 310 times that of carbon dioxide on a per mol basis. There is general agreement that, within wastewater treatment plants, the vast majority of the nitrous oxide emissions occur in the aerobic zones for biological ammonia oxidation and/or downstream from anoxic zones used in biological nitrogen removal. However, the exact mechanism of production is not well understood, as both incomplete nitrification and denitrification might contribute to the overall nitrous oxide emissions. Determining the dominant biological pathways responsible for these emissions is important for the development of improved treatment systems that can reduce nitrous oxide greenhouse gas emissions to the atmosphere. In this study, we determined the total nitrous oxide flux from a single tank of one of the aeration basins from a large metropolitan wastewater treatment plant in Stickney, Illinois. Furthermore, we analyzed the changes in nitrogen and oxigen stable isotopic composition for ammonium, nitrate, and nitrous oxide, as well as the intramolecular site preference (SP) for δ15N within the linear N-N-O molecule, along the 520 meter wastewater flow path within the tank. Assuming the measured tank was representative of the 32 tanks constituting the 4 aeration basins of the plant, we estimate the combined annual nitrous oxide flux from this source to be approximately 230 metric ton/y. The δ15N values for ammonium ranged between +19.9% and +6.4%, those for nitrate ranged between +20.4% and +5.3%, and those for nitrous oxide ranged between -34.4% and 0.4%. The nitrous oxide SP ranged between +11.7% and -4.5%. The concentrations and δ15N values of ammonium and nitrate showed trends along the

    2016-06-01

    Full Text Available The objective of this study was to evaluate the effect of organic and mineral fertilizers on the structure and production of Panicum maximum cv. Massai forage. The experiment was conducted at the teaching farm of Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte, Apodi Campus. The treatments evaluated were organic sources of nitrogen (wastes of pig, poultry and sheep farming and a mineral source (urea, set at 150 kg N/ha. Forage production, morphological components, pasture height, light interception, leaf area index, and chlorophyll content were evaluated in samples obtained at intervals of 60 days. Canopy height was affected by the type of fertilizer applied and the greatest height was observed for pasture fertilized with urea (50.97 cm. The highest light interception by the canopy was observed for pastures receiving urea, but 95% light interception was not reached. The leaf area index was higher for pastures fertilized with urea compared to the other treatments and the values obtained for pastures receiving organic fertilizers were considered very low. Forage, leaf blade, stem and dead material mass was affected by the type of fertilizer and was higher for pastures receiving urea. The total chlorophyll content of leaf blades did not differ between the types of fertilizer evaluated. Forage structure or production in massai grass pastures is not affected by the type of animal manure used as nitrogen source. The efficiency of these organic fertilizers as a nitrogen source is lower than that of mineral fertilization. The animal manures evaluated can be used as nitrogen sources for massai grass pastures to reduce costs and environmental impacts.

  20. Historic role of nuclear techniques in solving problems of animal production and health

    International Nuclear Information System (INIS)

    In reflecting on the role nuclear techniques have played in resolving the needs of developing country livestock keepers I have taken a slightly different approach to previous presentations in this area. I will view developments to date from the perspective of the user and beneficiary of such new knowledge. The paper will also attempt to put the work of the Animal Production and Health Section (APHS) into historical context, thus giving its future strategy a place in the development marathon. Efforts to assess the value of previous investments in nuclear techniques for the benefit of livestock farmers have been few and far between. Most of the earlier work focused on the contribution to new knowledge - the elaboration of metabolic pathways, unravelling the complexity of disease transmission or understanding the endocrine system feedbacks in relation to reproductive and metabolic hormones. Hence the products originally had more intellectual than economic/practical values. It is only relatively recently (last 20-30 years) that the more applied consequences of such knowledge have been used to help resolve some of the difficult problems facing third-world animal agriculture. This paper elaborates some of the past and present successes and future challenges in: Nutrition and feeding -from the use of isotopes (deuterium) in the investigation of metabolism in the rat in the 1930s to the use of stable (N15) and radio-isotopes (P32 and S35) in assessing new diet formulations and feeding standards for livestock in marginal environments. New 'political' targets in Africa to increase livestock productivity by 6% per annum provide new challenges to the livestock feed sector - for which the foregoing technologies are uniquely placed to address. Reproduction - from the use of competitive protein-binding assays (based on 3H) for various steroid and protein hormones to the use of rapid (I125 based) radioimmunoassay kits for quantifying progesterone levels -and thereby to detect

  1. Gene-based vaccine development for improving animal production in developing countries

    International Nuclear Information System (INIS)

    Full text: The cloning and expression of microbial genes in alternate hosts to enhance production of antigens for animal vaccines against all disease is theoretically achievable. It is essential, however, that antigens expressed in this way are known to be protective. Many years of costly research usually precedes the identification of such antigens or combinations of antigens. Thus, while conventional vaccines based on living, attenuated or inactivated microorganisms may be effective, the protective components contained in them i.e. the candidates for cloning, have yet to be found. The principal protective antigen in vaccines against foot rot of sheep and goats is fimbrial protein of Dichelobacter nodosus. Recombinant vaccines against this infection are ineffective if the protein subunits are not assembled and presented to the host in a manner morphologically indistinguishable from those of the natural fimbriae. Availability of recombinant antigen does not necessarily avoid the need for the use of adjuvants to potentiate response. Oil emulsion vaccines, while enhancing immune response, almost inevitably cause a marked reaction at the site of injection. Livestock owners in developing countries are as likely as those elsewhere to object to these reactions. The need to find an acceptable and effective formulation adds to the cost of recombinant vaccines and their application in countries with limited resources for disease control. Another costly feature of recombinant vaccines has been the patenting of processes involving gene technology and licencing agreements for production under the protection of these patents. In some systems antigenic competition between similar and disparate antigens limits the usefulness of even recombinant antigens that, administered individually, are highly potent. In the case of programs for the control and eventual eradication of footrot in sheep and goats in Nepal this problem was overcome by the prior identification of causal serotypes

    Farmers and ranchers depend on the successful combination of livestock and crops. However, they have lost in the production by nitrate pollution. Nitrate poisoning in cattle is caused by the consumption of an excessive amount of nitrate or nitrite from grazing or water. Both humans and livestock can be affected. It would appear that well fertilised pasture seems to take up nitrogen from the soil and store it as nitrate in the leaf. Climatic conditions, favour the uptake of nitrate. Nitrate poisoning is a noninfectious disease condition that affects domestic ruminants. It is a serious problem, often resulting in the death of many animals. When nitrogen fertilizers are used to enrich soils, nitrates may be carried by rain, irrigation and other surface waters through the soil into ground water. Human and animal wastes can also contribute to nitrate contamination of ground water. A possible method to decontaminate polluted water by nitrates is with methods of fabrication of zero valent iron nanoparticles (FeNps) are found to affect their efficiency in nitrate removal from water.

    Full Text Available The use of carbamate in Indonesia is relatively new, in particular after prohibition on the use of most organochlorines (OC. Carbamates that commonly used for agricultural activities are carbofuran (Furadan, aldicarb (Temik and carbaryl (Sevin. When properly used, they will provide benefit, but misuse of insecticides would affect productivity, poisoning, public health problems, environmental contamination and residues in foods. A monitoring result of carbamate used in Java indicates that carbofurans were detected in soils (0,8 – 56,3 ppb; water (0,1 – 5,0 ppb; rice (nd – 5,0 ppb; soybeans (1,2 – 610 ppb; animal feed (12 – 102 ppb; beef (110 – 269 ppb; and sera of beef cattle (167 – 721 ppb. The residue level was above the maximum residue limits (MRL released by Indonesian Standardization Agency (Badan Standardisasi Nasional in some samples. The presence of carbofuran in foods should be taken into account since the carbofuran is regarded highly toxic for public and animal health. This paper describes the toxicity of carbamate, clinical signs of poisoning, residue in foods and environment, handling of poisoning and residue control.

    An indirect competitive enzyme-linked immunosorbent assay (icELISA) based on the detection of the thermal-stable central nervous tissue (CNT) marker protein, myelin basic protein (MBP), was developed to detect animal CNT in processed meat and feedstuffs. Two meat samples (cooked at 100 °C for 30 min and autoclaved at 133 °C for 20 min) of bovine brain in beef and two feed samples (bovine brain meal in beef meal and in soybean meal) were prepared at levels of 0.0008, 0.0031, 0.0063, 0.0125, 0.025, 0.05, 0.1, 0.2, 0.4, 0.8, and 1.6%. An anti-MBP monoclonal antibody (mAb3E3) was produced using the hybridoma technique and characterized using Western blot. The optimized icELISA was CNT-specific without cross-reactivity with either meat (beef and pork) or soybean meal samples and had low intra-assay (%CV ≤ 3.5) and interassay variability (%CV ≤ 3.3), with low detection limits for bovine MBP (6.4 ppb) and bovine CNT spiked in both meat (0.05%) and feed (0.0125%) samples. This assay is therefore suitable for the quantitative detection of trace amounts of contaminated animal CNT in processed food and feed products.

    The use of medicated feed is a common practice in animal food production to improve animal health. Tetracyclines and β-Lactams are the groups that are most frequently added to this type of feed. The measurement of the concentration of the analytes in these types of samples is sometimes due to the matrix characteristic, and manufacturers are demanding fast, precise and reproducible methods. A rapid confirmatory method based on a simple extraction protocol using acidified methanol and followed by high performance liquid chromatography coupled to a tandem mass spectrometer for the quantification of four tetracyclines in feed is presented. Validation was performed following the guidelines of Decision 2002/657/EC. Results indicated that the four tetracyclines can be identified and quantified in a concentration range between 50 and 500 mg/kg with recoveries between 84% and 109% and RSD for precision under reproducible conditions between 12% and 16%. Satisfactory results were also obtained with interlaboratory studies and by comparing the method with an HPLC-Fluorescent method.

    Full Text Available A comprehensive understanding of the link between water footprint and energy content of crop and animal products is vitally important for the sound management of water resources. In this study, we developed a mathematical relationship between water content, and energy content of many crops and animal products by using an improved LCA approach (water footprint. The standard values of the water and energy contents of crops and animal products were obtained from the databases of Agricultural Research Service, UNESCO Institute for water education and Food, and Agriculture Organization of the United Nations. The water footprint approach was applied to analyze the relationship between water requirement and energy of content of crop and animal products, in which the uncertainty and sensitivity was evaluated by Monte Carlo simulation technique that is contained in the Oracle Crystal Ball Fusion Edition v11.1.1.3.00. The results revealed significant water saving due to changes in food consumption pattern i.e. from consumption of more meat to vegetables. The production of 1kcal of crop and animal products requires about 98% of green, 4.8% blue water and 0.4% of gray water. In which changes in consumption pattern gave annual blue water saving of about 1605 Mm3 that is equivalent to 41.30m3/capita, extremely greater than the standard drinking water requirement for the whole population. Moreover, the projected results indicated, triple increase of dietary water requirement from 30.9 Mm3 in 2005 to 108 Mm3 by 2050. It was also inferred that, Tanzania has a positive virtual water balance of crop and animal products consumption with net virtual water import of 9.1 Mm3 that is the contribution margin to the water scarcity alleviation strategy. Therefore, developed relationship of water footprint and energy content of crops and animal products can be used by water resource experts for sustainable freshwater and food supply.

    In livestock production, lactic acid bacteria (LAB) are the most common microorganisms used as probiotics. For such use, these bacteria must be correctly identified and characterized to ensure their safety and efficiency. In the present study, LAB were isolated from broiler excreta, where a fermentation process was used. Nine among sixteen isolates were identified by biochemical and molecular (sequencing of the 16S rRNA gene) methods as Lactobacillus crispatus (n=1), Lactobacillus pentosus (n=1), Weissella cibaria (n=1), Pediococcus pentosaceus (n=2) and Enterococcus hirae (n=4). Subsequently, these bacteria were characterized for their growth capabilities, lactic acid production, acidic pH and bile salts tolerance, cell surface hydrophobicity, antimicrobial susceptibility and antagonistic activity. Lactobacillus pentosus strain LB-31, which showed the best characteristics, was selected for further analysis. This strain was administered to broilers and showed the ability of modulating the immune response and producing beneficial effects on morpho-physiological, productive and health indicators of the animals.

  11. Application of near infrared spectroscopy to improve animal production in developing countries

    International Nuclear Information System (INIS)

    Near infrared (NIR) spectroscopy is an analytical technique measuring light absorption in the 780-2 500 nm region which is closely related to important chemical bonds (OH, NH and CH). NIR can be used to measure many nutritionally important constituents of concentrate and forage feeds, and from NIR spectra of faeces (i.e. dung) many constituents of the diet of grazing livestock. NIR depends on the development, in representative sets of samples, of mathematical relationships (calibration equations) between spectra and the constituents or attributes measured by conventional chemistry, and then application of these calibrations to estimate the constituents in unknown samples. These NIR calibration equations tend to be specific to the circumstances of the data used for their development. Application of NIR technology to livestock nutrition allows rapid, routine and economical analysis of feedstuffs and ingredients for compounded diets or supplements, thus improving stockfeed manufacture. Also NIR analysis of faeces allows estimation of the diet selected by grazing livestock and in small holder farming systems; this is not possible with any other technology. However, NIR instrumentation requires substantial capital investment, and considerable technical skills are required to develop and maintain calibration equations. Application of NIR technology allows established knowledge of the science of animal nutrition to be readily and objectively applied to improve productivity and cost-effectiveness of livestock production systems. Widespread use of this technology in developing countries would greatly improve quality control in manufacturing livestock feeds and application of existing nutritional knowledge to increase productivity and cost-effectiveness of livestock production.

  12. Modeling the dynamics of radionuclide concentration in animal derived products after an accident in tropical areas

    International Nuclear Information System (INIS)

    Following an accidental release of radionuclides to the atmosphere with the contamination of large areas, a detailed and fast methodology to assess the prognosis of public exposure is needed to estimate radiological consequences and optimize decisions to the protection of the public. The German model ECOSYS has been chosen to integrate the SIEM - Integrated Emergency System, developed by IRD/CNEN to assess the doses to the public after an accidental contamination of rural areas. The use the model demands a considerable effort in adapting scenarios to fit the specific conditions of a location, considering the differences related to climate, environmental characteristics, agricultural calendar and practices, along with population diet. The area selected to start this adaptation considers the characteristics of the 50 km radius area surrounding the nuclear power plants at Angra dos Reis, Rio de Janeiro. At a first stage, the concentration on vegetal food products has been studied. This work describes the methodology used to select scenarios and presents results of the dynamics of the predicted concentration of radionuclides in different kinds of animal derived food products. The work provides guidance to the need of radioecological research needed to improve the adequacy of the estimates to actual Brazilian scenarios. (author)

    Category 2 animal by-products that need to be sterilized with steam pressure according Regulation (EC) 1774/2002 are studied. In this work, 2 sets of experiments were performed in mesophilic conditions: (i) biomethane potential determination testing 0.5%, 2.0% and 5.0% total solids (TS), using sludge from the anaerobic digester of a wastewater treatment plant as inoculum; (ii) biodegradability tests at a constant TS concentration of 2.0% and different inoculum sources (digested sludge from a wastewater treatment plant; granular sludge from an upflow anaerobic sludge blanket reactor; leachate from a municipal solid waste landfill; and sludge from the slaughterhouse wastewater treatment anaerobic lagoon) to select the more adapted inoculum to the substrate in study. The higher specific methane production was of 317 mL CH(4)g(-1) VS(substrate) for 2.0% TS. The digested sludge from the wastewater treatment plant led to the lowest lag-phase period and higher methane potential rate. PMID:22989655

    Full Text Available The primary goal of dairy industry has been to identify an efficient and economical way of increasing milk production and its constituents without increasing the size of the dairy herd. The use of milk protein polymorphisms as detectable molecular markers has been studied intensively because of their effect on the yield and processing properties of milk and its products. Thus, molecular markers are promising alternative to the current methods of trait selection once these genes are proven to be associated with traits of interest in animals. Kappa-casein (CSN3 and beta-lactoglobulin (BLG are two of the most important proteins in the milk of mammals that play a crucial role in the milk quality and coagulation, an essential process for cheese and butter. The A and B variant of k-casein and β-lactoglobulin were distinguished by Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP analysis in 108 Romanian Simmental and 60 Holstein Friesian cattle.

    veterinary inputs (disease control) and improving feeding through livestock extension services. This should be accompanied by improvements in the breeding stock and marketing arrangements for goats, and by access to rangeland with adequate water and grazing. Through livestock extension services, small-scale farmers should be encouraged to adopt a number of existing animal husbandry technologies such as: (i) preservation and utilization of crop residues for supplementary feeding; (ii) de-worming of livestock; (iii) take farming as a business and learn to market their goats and livestock regularly utilize market incentive schemes; and (iv) rotational grazing on communal rangelands. The lack of record keeping among small-scale farmers needs attention in particular in view of the globalization of agricultural markets, which may require farm records for traceability of products. The need for reliable and globally acceptable recording systems will therefore become inevitable for globally traded products. The government through extension service should promote record keeping among farming communities and organizations including small-scale goat farmers. It should also link recording keeping to institutions (universities e.g. UNAM) with technical capacity to process the data in timely manner and interpret the results for farmers' immediate use in management decisions. Finally, there is great potential for goats to contribute more to the livelihood of the people in the NCAs. Early and major productivity gains can come through improved husbandry practices (feeding), veterinary services (to reduce losses to diseases) and marketing (to increase off-take). Breed improvement is a possibility but takes time and sustainability is in low-input smallholder conditions is uncertain. (author)

  20. The utility of captive animals in actualistic research: A geometric morphometric exploration of the tooth row of Alligator mississippiensis suggesting ecophenotypic influences and functional constraints.

    Captive broad snouted crocodylians are generally thought to have wider, shorter rostra than their wild counterparts. Interpreted to reflect morphological change in response to the conditions of captivity, this qualitative pattern could affect the utility of these animals in a variety of fields of research. However, due to relative ease of access and availability of life history data, captive animals are often utilized in actualistic research. Thus, this issue should be addressed in more detail. Here we explore snout shape variation between captive and wild members of Alligator mississippiensis using two-dimensional (2D) morphometric techniques. Several landmark schemesare used to assess the utility of different aspects of morphology in distinguishing the groups. While statistical analyses consistently differentiated between the groups, the area of morphospace occupied by wild members of A. mississippiensis generally overlapped with the larger area encompassing the captive specimens. This indicates that the captive condition is not as uniform as previously thought and instead encompasses a large spectrum of morphologies, ranging from the stereotypical broad, shortened snouts to outlines that are indistinguishable from the wild morphotype. These results align well with the interpretation that this change reflects an extreme example of ecophenotypy, since ranched, farmed, or zoo organisms are held in an array of enclosures, ranging from indoor, climate controlled pens to outdoor, more natural areas. This variation in environments should be reflected in different reactions to the animals' surroundings, resulting in a broad spectrum of morphotypes. While wild specimens are still preferred, especially for fine scale analyses, these results indicate that not all captive members of A. mississippiensis exhibit the extreme morphological alterations often cited in the literature. Weighing the conditions in which the animals are held and exploring the possibility of

    The scientific basis and advantages of using recently developed CRISPR/Cas-9 technology for transgenesis have been assessed with respect to other production methods, laboratory animal welfare, and the scientific relevance of transgenic models of human diseases in general. As the new technology is straightforward, causes targeted DNA double strand breaks and can result in homozygous changes in a single step, it is more accurate and more efficient than other production methods and speeds up transgenesis. CRISPR/Cas-9 also obviates the use of embryonic stem cells, and is being used to generate transgenic non-human primates (NHPs). While the use of this method reduces the level of animal wastage resulting from the production of each new strain, any long-term contribution to reduction will be offset by the overall increase in the numbers of transgenic animals likely to result from its widespread usage. Likewise, the contribution to refinement of using a more-precise technique, thereby minimising the occurrence of unwanted genetic effects, will be countered by a probable substantial increase in the production of transgenic strains of increasingly sentient species. For ethical and welfare reasons, we believe that the generation of transgenic NHPs should be allowed only in extremely exceptional circumstances. In addition, we present information, which, on both welfare and scientific grounds, leads us to question the current policy of generating ever-more new transgenic models in light of the general failure of many of them, after over two decades of ubiquitous use, to result in significant advances in the understanding and treatment of many key human diseases. Because this unsatisfactory situation is likely to be due to inherent, as well as possibly avoidable, limitations in the transgenic approach to studying disease, which are briefly reviewed, it is concluded that a thorough reappraisal of the rationale for using genetically-altered animals in fundamental research and

  2. Removing constraints on the biomass production of freshwater macroalgae by manipulating water exchange to manage nutrient flux.

    Directory of Open Access Journals (Sweden)

    Andrew J Cole

    Full Text Available Freshwater macroalgae represent a largely overlooked group of phototrophic organisms that could play an important role within an industrial ecology context in both utilising waste nutrients and water and supplying biomass for animal feeds and renewable chemicals and fuels. This study used water from the intensive aquaculture of freshwater fish (Barramundi to examine how the biomass production rate and protein content of the freshwater macroalga Oedogonium responds to increasing the flux of nutrients and carbon, by either increasing water exchange rates or through the addition of supplementary nitrogen and CO2. Biomass production rates were highest at low flow rates (0.1-1 vol.day-1 using raw pond water. The addition of CO2 to cultures increased biomass production rates by between 2 and 25% with this effect strongest at low water exchange rates. Paradoxically, the addition of nitrogen to cultures decreased productivity, especially at low water exchange rates. The optimal culture of Oedogonium occurred at flow rates of between 0.5-1 vol.day-1, where uptake rates peaked at 1.09 g.m-2.day-1 for nitrogen and 0.13 g.m-2.day-1 for phosphorous. At these flow rates Oedogonium biomass had uptake efficiencies of 75.2% for nitrogen and 22.1% for phosphorous. In this study a nitrogen flux of 1.45 g.m-2.day-1 and a phosphorous flux of 0.6 g.m-2.day-1 was the minimum required to maintain the growth of Oedogonium at 16-17 g DW.m-2.day-1 and a crude protein content of 25%. A simple model of minimum inputs shows that for every gram of dry weight biomass production (g DW.m-2.day-1, Oedogonium requires 0.09 g.m-2.day-1 of nitrogen and 0.04 g.m-2.day-1 of phosphorous to maintain growth without nutrient limitation whilst simultaneously maintaining a high-nutrient uptake rate and efficiency. As such the integrated culture of freshwater macroalgae with aquaculture for the purposes of nutrient recovery is a feasible solution for the bioremediation of wastewater and the

    The Texas Panhandle is regarded as the "Cattle Feeding Capital of the World", producing 42% of the fed beef cattle in the United States within a 200-mile radius of Amarillo generating more than 5 million tons of feedlot manure /year. Apart from feedlots, the Bosque River Region in Erath County, just north of Waco, Texas with about 110,000 dairy cattle in over 250 dairies, produces 1.8 million tons of manure biomass (excreted plus bedding) per year. While the feedlot manure has been used extensively for irrigated and dry land crop production, most dairies, as well as other concentrated animal feeding operations (CAFO's), the dairy farms utilize large lagoon areas to store wet animal biomass. Water runoff from these lagoons has been held responsible for the increased concentration of phosphorus and other contaminates in the Bosque River which drains into Lake Waco—the primary source of potable water for Waco's 108,500 people. The concentrated animal feeding operations may lead to land, water, and air pollution if waste handling systems and storage and treatment structures are not properly managed. Manure-based biomass (MBB) has the potential to be a source of green energy at large coal-fired power plants and on smaller-scale combustion systems at or near confined animal feeding operations. Although MBB particularly cattle biomass (CB) is a low quality fuel with an inferior heat value compared to coal and other fossil fuels, the concentration of it at large animal feeding operations can make it a viable source of fuel. The overall objective of this interdisciplinary proposal is to develop environmentally benign technologies to convert low-value inventories of dairy and beef cattle biomass into renewable energy. Current research expands the suite of technologies by which cattle biomass (CB: manure, and premature mortalities) could serve as a renewable alternative to fossil fuel.

    Influential theories have claimed that the ability for recursion forms the computational core of human language faculty distinguishing our communication system from that of other animals (Hauser, Chomsky, & Fitch, 2002). In the present study, we consider an alternative view on recursion by studying the contribution of associative and working memory processes. After an intensive paired-associate training with visual shapes, we observed that baboons spontaneously ordered their responses in keeping with a recursive, centre-embedded structure. This result suggests that the human ability for recursion might partly if not entirely originate from fundamental processing constraints already present in nonhuman primates and that the critical distinction between animal communication and human language should more likely be found in working memory capacities than in an ability to produce recursive structures per se.

    The overall aim of the present study was to analyse and compare organic beef cattle farming in Spain with intensive and conventional systems. An on-farm study comparing farm management practices and animal health was carried out. The study also focussed on a slaughterhouse analysis by comparing impacts on the safety and quality of the cattle products. Twenty-four organic and 26 conventional farms were inspected, and farmers responded to a questionnaire that covered all basic data on their husbandry practices, farm management, veterinary treatments and reproductive performance during 2007. Furthermore, data on the hygiene and quality of 244, 2596 and 3021 carcasses of calves from organic, intensive and conventional farms, respectively, were retrieved from the official yearbook (2007) of a slaughterhouse. Differences found between organic and conventional farms across the farm analysis did not substantially reflect differences between both farm types in the predominant diseases that usually occur on beef cattle farms. However, calves reared organically presented fewer condemnations at slaughter compared with intensive and to a lesser extent with conventionally reared calves. Carcass performance also reflected differences between farm type and breed and was not necessarily better in organic farms.

    The chemical properties of liquid fermented products (LFP) as probiotics substance for alternative uses of antibiotic were studied. The LFP of 235 were sampling from markets and farmers during 2005-2006. The total count of bacteria, fungi, lactic acid bacteria (LAB), Actinomyces and coliform bacteria were conducted. Chemical analysis of LFP showed medium nitrogen (0.01- 0.55%), maximum sugar contents (0.02 - 19.40%), high lactic acid contents (0.34 - 13.01%) and low pH (2.9-5.0). LFPs were free from fecal coliform and Escherichia coil (Ec); but in LAB (1.0 - 1.25x107 cfu/ml) and high Actinomyces (1.0 - 7.5 x 106 cfu/ml). LFPs inhibited Staphylococcus aureus (Sa), Samonella typhimurium (STM), Escherichia coil (Ec) and Ec 0157 at maximum yield by using Minimal Inhibition Concentration (MIC). But Pseudomonas aeruginosa (Pa) could medium inhibited. Therefore LFP samples are suitable as probiotics for alternative use of antibiotic for animal raising.

    The Texas Panhandle is regarded as the 'Cattle Feeding Capital of the World', producing 42% of the fed beef cattle in the United States within a 200-mile radius of Amarillo generating more than 5 million tons of feedlot manure/year. Apart from feedlots, the Bosque River Region in Erath County, just north of Waco, Texas with about 110,000 dairy cattle in over 250 dairies, produces 1.8 million tons of manure biomass (excreted plus bedding) per year. While the feedlot manure has been used extensively for irrigated and dry land crop production, most dairies, as well as other concentrated animal feeding operations (CAFO's), the dairy farms utilize large lagoon areas to store wet animal biomass. Water runoff from these lagoons has been held responsible for the increased concentration of phosphorus and other contaminates in the Bosque River which drains into Lake Waco - the primary source of potable water for Waco's 108,500 people. The concentrated animal feeding operations may lead to land, water, and air pollution if waste handling systems and storage and treatment structures are not properly managed. Manure-based biomass (MBB) has the potential to be a source of green energy at large coal-fired power plants and on smaller-scale combustion systems at or near confined animal feeding operations. Although MBB particularly cattle biomass (CB) is a low quality fuel with an inferior heat value compared to coal and other fossil fuels, the concentration of it at large animal feeding operations can make it a viable source of fuel. The overall objective of this interdisciplinary proposal is to develop environmentally benign technologies to convert low-value inventories of dairy and beef cattle biomass into renewable energy. Current research expands the suite of technologies by which cattle biomass (CB: manure, and premature mortalities) could serve as a renewable alternative to fossil fuel. The work falls into two broad categories of research and development

  18. Safety evaluations under the proposed US Safe Cosmetics and Personal Care Products Act of 2013: animal use and cost estimates.

    Knight, Jean; Rovida, Costanca

    2014-01-01

    The proposed Safe Cosmetics and Personal Care Products Act of 2013 calls for a new evaluation program for cosmetic ingredients in the US, with the new assessments initially dependent on expanded animal testing. This paper considers possible testing scenarios under the proposed Act and estimates the number of test animals and cost under each scenario. It focuses on the impact for the first 10 years of testing, the period of greatest impact on animals and costs. The analysis suggests the first 10 years of testing under the Act could evaluate, at most, about 50% of ingredients used in cosmetics. Testing during this period would cost about $ 1.7-$ 9 billion and 1-11.5 million animals. By test year 10, alternative, high-throughput test methods under development are expected to be available, replacing animal testing and allowing rapid evaluation of all ingredients. Given the high cost in dollars and animal lives of the first 10 years for only about half of ingredients, a better choice may be to accelerate development of high-throughput methods. This would allow evaluation of 100% of cosmetic ingredients before year 10 at lower cost and without animal testing. PMID:24468774

  19. Evaluation of different techniques to control hydrogen sulfide and greenhouse gases from animal production systems

    Gautam, Dhan Prasad

    The livestock manure management sector is one of the prime sources for the emission of greenhouse gases (GHGs) and other pollutant gases such as ammonia (NH3) and hydrogen sulfide (H2S), which may affect the human health, animal welfare, and the environment. So, worldwide investigations are going on to mitigate these gaseous emissions. The overall objective of this research was to investigate different approaches (dietary manipulation and nanotechnology) for mitigating the gaseous emissions from livestock manure system. A field study was conducted to investigate the effect of different levels of dietary proteins (12 and 16%) and fat levels (3 to 5.5%) fed to beef cattle on gaseous emission (methane-CH4, nitrous oxide-N2O, carbon dioxide-CO 2 and hydrogen sulfide-H2S) from the pen surface. To evaluate the effects of different nanoparticles (zinc oxide-nZnO; and zirconium-nZrO 2) on these gaseous emissions from livestock manure stored under anaerobic conditions, laboratory studies were conducted with different treatments (control, bare NPs, NPs entrapped alginate beads applying freely and keeping in bags, and used NPs entrapped alginate beads). Field studies showed no significant differences in the GHG and H2S emissions from the manure pen surface. Between nZnO and nZrO2, nZnO outperformed the nZrO2 in terms of gases production and concentration reduction from both swine and dairy liquid manure. Application of nZnO at a rate of 3 g L-1 showed up to 82, 78, 40 and 99% reduction on total gas production, CH 4, CO2 and H2S concentrations, respectively. The effectiveness of nZnO entrapped alginate (alginate-nZnO) beads was statistically lower than the bare nZnO, but both of them were very effective in reducing gas production and concentrations. These gaseous reductions were likely due to combination of microbial inhibition of microorganisms and chemical conversion during the treatment, which was confirmed by microbial plate count, SEM-EDS, and XPS analysis.

    In the past years, there has been a remarkable development of high-throughput omics (HTO) technologies such as genomics, epigenomics, transcriptomics, proteomics and metabolomics across all facets of biology. This has spearheaded the progress of the systems biology era, including applications on animal production and health traits. However, notwithstanding these new HTO technologies, there remains an emerging challenge in data analysis. On the one hand, different HTO technologies judged on their own merit are appropriate for the identification of disease-causing genes, biomarkers for prevention and drug targets for the treatment of diseases and for individualized genomic predictions of performance or disease risks. On the other hand, integration of multi-omic data and joint modelling and analyses are very powerful and accurate to understand the systems biology of healthy and sustainable production of animals. We present an overview of current and emerging HTO technologies each with a focus on their applications in animal and veterinary sciences before introducing an integrative systems genomics framework for analysing and integrating multi-omic data towards improved animal production, health and welfare. We conclude that there are big challenges in multi-omic data integration, modelling and systems-level analyses, particularly with the fast emerging HTO technologies. We highlight existing and emerging systems genomics approaches and discuss how they contribute to our understanding of the biology of complex traits or diseases and holistic improvement of production performance, disease resistance and welfare.

    Background: The aim of this paper is to propose a risk based surveillance model for environmental pollutants, monitoring the presence and the quantity of toxic contaminants in cattle and sheep products.

    Methods: The province of Latina was chosen as study area. The official list of polluted sites was provided by the Province. This was then integrated into a Geographic Informative System together with geographical, hydrographic, and geological data along with information regarding the farms that was obtained from the National Livestock Registry. In order to identify the monitoring priority of polluted sites, a semi-quantitative risk assessment was then set up. A score for each of the attributes considered in the risk evaluation was given to each site, based on two main criteria: the environmental hazard characterization and the quantification of the exposed animal population. The sample of farms to be monitored was defined according to statistical criteria.

    Results: 12 polluted sites were chosen as “at major risk” among the 58 identified therefore, inside the respective surrounding risk areas, 24 farms were chosen to be monitored. Biological materials to be sampled were also defined. As a result, it was determined that 104 samples collected throughout a year would be sufficient to detect any contamination in the territory of the Province, with an admitted prevalence of 10% among farms at risk (CL 95%.

    Conclusions: Risk based surveillance is more sensitive in detecting environmental pollution than surveillance that is randomly performed, based on the same allocation of financial resources.

    2013-07-01

    Full Text Available In accordance with Article 6 of Regulation (EC No 396/2005, the United Kingdom, hereafter referred to as the evaluating Member State (EMS, received an application from ISK Biosciences Europe SA to set new MRLs for the active substance pyriofenone in cereal grains and grapes. In order to accommodate for the intended uses of pyriofenone in northern and southern EU, the United Kingdom proposed to set an MRL of 0.01* mg/kg in wheat and rye, 0.05 mg/kg in barley and oats and 0.3 mg/kg in grapes. The United Kingdom drafted an evaluation report in accordance with Article 8 of Regulation (EC No 396/2005, which was submitted to the European Commission and forwarded to EFSA. According to EFSA, the data are sufficient to derive MRL proposals of 0.01* mg/kg for the intended uses on wheat and rye, 0.03 mg/kg for barley and oats reflecting the intended NEU uses and 0.3 mg/kg for grapes. The MRL proposal of 0.01* mg/kg derived for wheat is also applicable to triticale and spelt. Based on the intended uses, the setting of MRLs for animal products is not necessary. Adequate analytical enforcement methods are available to control the residues of pyriofenone in cereals and grapes. Based on the risk assessment results, EFSA concludes that the proposed uses of pyriofenone on cereal grains and grapes will not result in a consumer exposure exceeding the toxicological reference value and therefore, are unlikely to pose a consumer health risk.

  13. Forensic DNA barcoding and bio-response studies of animal horn products used in traditional medicine.

    Directory of Open Access Journals (Sweden)

    Dan Yan

    Full Text Available BACKGROUND: Animal horns (AHs have been applied to traditional medicine for more than thousands of years, of which clinical effects have been confirmed by the history. But now parts of AHs have been listed in the items of wildlife conservation, which limits the use for traditional medicine. The contradiction between the development of traditional medicine and the protection of wild resources has already become the common concern of zoophilists, traditional medical professionals, economists, sociologists. We believe that to strengthen the identification for threatened animals, to prevent the circulation of them, and to seek fertile animals of corresponding bioactivities as substitutes are effective strategies to solve this problem. METHODOLOGY/PRINCIPAL FINDINGS: A powerful technique of DNA barcoding based on the mitochondrial gene cytochrome c oxidase I (COI was used to identify threatened animals of Bovidae and Cervidae, as well as their illegal adulterants (including 10 species and 47 specimens. Meanwhile, the microcalorimetric technique was used to characterize the differences of bio-responses when those animal specimens acted on model organism (Escherichia coli. We found that the COI gene could be used as a universal primer to identify threatened animals and illegal adulterants mentioned above. By analyzing 223 mitochondrial COI sequences, a 100% identification success rate was achieved. We further found that the horns of Mongolian Gazelle and Red Deer could be exploited as a substitute for some functions of endangered Saiga Antelope and Sika Deer in traditional medicine, respectively. CONCLUSION/SIGNIFICANCE: Although it needs a more comprehensive evaluation of bioequivalence in order to completely solve the problem of substitutes for threatened animals, we believe that the identification (DNA barcoding of threatened animals combined with seeking substitutions (bio-response can yet be regarded as a valid strategy for establishing a balance

    Full Text Available Non-healing wounds are associated with high morbidity and might greatly impact a patient’s well-being and economic status. For many years, scientific research has focused on developing and testing several natural and synthetic materials that enhance the rate of wound healing or eliminate healing complications. Honey has been used for thousands of years as a traditional remedy for many ailments. Recently, honey has reemerged as a promising wound care product especially for infected wounds and for wounds in diabetic patients. In addition to its proposed potent broad-spectrum antibacterial properties, honey has been claimed to promote wound healing by reducing wound hyperaemia, oedema, and exudate, and by stimulating angiogenesis, granulation tissue formation and epithelialisation. Several animal models, including large animals, dogs and cats, and different species of laboratory animals have been used to investigate the efficacy and safety of various natural and synthetic agents for wound healing enhancement. Interpreting the results obtained by these studies is, however, rather difficult and usually hampered by many limiting factors including great variation in types and origins of honey, the type of animal species used as models, the type of wounds, the number of animals, the number and type of controls, and variation in treatment protocols. In this article, we provide a comprehensive review of the most recent findings and applications of published experimental and clinical trials using honey as an agent for wound healing enhancement in different animal models.

  16. The Profitability of Animal Husbandry Activities on Farms in Dry Farming Areas and the Interaction between Crop Production and Animal Husbandry: The Case of Ankara Province in Turkey

    Directory of Open Access Journals (Sweden)

    Harun Tanrıvermis

    2007-04-01

    Full Text Available This paper examines the linkages between livestock and crop farming activities and provides a comparative analysis of the profitability of different livestock activities in the highlands of Ankara. The data was collected from 52 sample farms in the Nallıhan, Aya¸s, Güdül and Beypazarı districts of Ankara by way of a questionnaire, where the farms have, on average, 20.7 ha of land and are thus regarded as small family farms. Insufficient irrigated land and working capital, weak market relations and the pressure of high population brings about a requirement to strengthen crop-livestock interaction. Production on the farms is generally carried out in extensive conditions, with goat, sheep and cattle husbandry in addition to crop production. Crop production makes up for 20.8% of the total gross production value on the farms. Of this figure, the entire yields of wheat, barley, pulses, straw and fodder crops are used for own consumption by the households, along with 74% of the wheat and 77% of the barley produced. The research results indicate that the current management systems may be defined as mixed farms in terms of crop–livestock linkages. The average total income of the households surveyed is 9,412.0 USD, of which 63.4% comes from farming activities. Every 1 USD invested in animal husbandry provides an income of 1.12 USD from dairy cattle breeding, 1.13 USD from Angora goat breeding, 1.16 USD from sheep breeding and 1.27 USD from ordinary goat breeding. It has been found that ordinary goat breeding, which provides the greatest relative profitability for the farms, offers many advantages, and that the transition from Angora goat breeding to ordinary goat breeding through the breeding of ordinary male goats into the Angora herd has occurred in recent years. The results of the survey indicate that supporting crop production with animal husbandry is considered a requirement in order to maintain economic and social sustainability in the farms

    Oi, Misato; Saito, Hirofumi; Li, Zongfeng; Zhao, Wenjun

    2013-04-01

    To examine the neural mechanism of co-speech gesture production, we measured brain activity of bilinguals during an animation-narration task using near-infrared spectroscopy. The task of the participants was to watch two stories via an animated cartoon, and then narrate the contents in their first language (Ll) and second language (L2), respectively. The participants showed significantly more gestures in L2 than in L1. The number of gestures lowered at the ending part of the narration in L1, but not in L2. Analyses of concentration changes of oxygenated hemoglobin revealed that activation of the left inferior frontal gyrus (IFG) significantly increased during gesture production, while activation of the left posterior superior temporal sulcus (pSTS) significantly decreased in line with an increase in the left IFG. These brain activation patterns suggest that the left IFG is involved in the gesture production, and the left pSTS is modulated by the speech load.

  18. What is the form of the productivity-animal-species-richness relationship? A critical review and meta-analysis.

    2012-10-01

    The nature of the relationship between productivity and species richness has remained controversial for at least two decades. Recently authors have favored the suggestion that the form of this relationship is highly variable and scale dependent. However, this conclusion is not universally accepted. Here we present the results of a meta-analysis of animal productivity-species-richness relationships (PSRR) in terrestrial and freshwater ecosystems. Initially, 374 separate cases from 273 published studies were identified as potential tests of the animal PSRR. After critically assessing each study, 115 cases were accepted as robust tests of the relationship, and of these 95 had data available for formal meta-analysis. Contrary to expectation, we found no support for the form of the relationship being scale dependent; positive relationships predominated at all scales (geographical extents and grains). Furthermore, positive relationships were the most common form of the animal PSRR in both terrestrial and freshwater ecosystems and among vertebrates, invertebrates, homeotherms and poikilotherms. Therefore, our results also contrast with previous reviews that suggest no particular form of the PSRR is predominant. We demonstrate that the method used for classifying the form of PSRRs is critical to the result and that previous reviews may have been too liberal toward classifying the form of relationships as unimodal. The tendency for positive relationships between productivity and species richness across diverse animal taxa has important implications for understanding the mechanisms behind the latitudinal gradient in species richness.
