Full text: Poultry biodiversity conservation is a great challenge for many countries. Within the last several years, the number of endangered local breeds has increased, leading to a considerable loss of genetic resources. A similar trend was observed among the poultry breeds, including chicken, local turkey and goose breeds/lines established in Bulgaria, part of which is definitely lost. Currently these breeds/lines are at risk and/or threatened with extinction. The information obtained by phenotypic characterization of these breeds is the first step for planning the management of poultry genetic resources through setting up improved selection schemes and conservation strategies. In this paper, we reviewed the current state of knowledge regarding the morphological and phenotypic diversity of local poultry breeds and some old productive poultry lines in Bulgaria. (author)

1982-01-01

A demonstration conducted last winter at the Tip Top Poultry Plant intended to show poultry plant managers from all over the U.S. potential solutions to the problem of plant noise. Plastic covers used over sound absorbing materials need to meet cleanability requirements, high- pressure water cleaning and other harsh maintenance procedures peculiar to the poultry processing industry. For the demonstration, Fiber Flex, Inc. manufactured and donated 750 noise panels; Owens-Corning Fiberglas Corporation donated the fiberglas cores; and the cover material was purchased from Howe and Bainbridge. The Engineering Experiment Station (EES) conducted before and after noise surveys and is evaluating the effect of noise reduction on turnover and productivity in the demonstration plant. EES plans to conduct a noise abatement workshop and update a handbook to help poultry processors with noise problems. EES study and demonstration may be applicable to other food processing plants where similar sanitary constraints exist.

Poultry are one of the most badly treated animals in the modern world. It has been shown that they have high levels of both cognition and feelings, and as a result there has been a recent trend of promoting poultry welfare. There is also a tradition of keeping poultry as pets in some parts of the world. However, in modern cities and societies, it is often difficult to maintain contact with pets, particularly for office workers. We propose and describe a novel cybernetics system to use mobile and Internet technology to improve human-pet interaction. It can also be used for people who are allergic to touching animals and thus cannot stroke them directly. This interaction encompasses both visualization and tactile sensation of real objects.

2015-12-01

The poultry sector is an important and vibrant segment of agriculture in Pakistan with a significant contribution to the national GDP (1.3%). Commercial poultry production in Pakistan started in the 1960's and has been providing a significant portion of daily proteins to the Pakistani population ever since. During its evolution the industry enjoyed promotional policies of the Government, but has faced several challenges such as disease outbreaks and retail price fluctuations. Despite its important role in the country's economy, not a single scientific study is available on its evolutionary history. The data available in this regard are scattered and lack reliability. This review is an effort to encompass the history of the overall growth of the poultry industry in Pakistan, its present status (2012 statistics) and future directions and challenges. This article may serve as the basic source of information on Pakistan's poultry industry achievements. It will also guide poultry experts and policy makers for developing strategic planning for further growth of the industry.

Full Text Available Consideration of animal welfare is essential to address the consumers’ demands and for the long term sustainability of commercial poultry. However, assessing welfare in large poultry flocks, to be able to detect potential welfare risks and to control or minimize its impact is difficult. Current developments in technology and mathematical modelling open new possibilities for real-time automatic monitoring of animal welfare and health. New technological innovations potentially adaptable to commercial poultry are appearing, although their practical implementation is still being defined. In this paper, we review the latest technological developments with potential to be applied to poultry welfare, especially for broiler chickens and laying hens. Some of the examples that are presented and discussed include the following: sensors for farm environmental monitoring, movement, or physiological parameters; imaging technologies such as optical flow to detect gait problems and feather pecking; infrared technologies to evaluate birds’ thermoregulatory features and metabolism changes, that may be indicative of welfare, health and management problems. All these technologies have the potential to be implemented at the commercial level to improve birds’ welfare and to optimize flock management, therefore, improving the efficiency of the system in terms of use of resources and, thus, long term sustainability.

Full Text Available Since 2004, 21 highly pathogenic avian influenza H5N1 outbreaks in domestic poultry and eight human cases have been confirmed in Cambodia. As a result, a large number of avian influenza education campaigns have been ongoing in provinces in which H5N1outbreaks have occurred in humans and/or domestic poultry.Data were collected from 1,252 adults >15 years old living in two southern provinces in Cambodia where H5N1 has been confirmed in domestic poultry and human populations using two cross-sectional surveys conducted in January 2006 and in November/December 2007. Poultry handling behaviors, poultry mortality occurrence and self-reported notification of suspect H5N1 poultry cases to animal health officials in these two surveys were evaluated. Our results demonstrate that although some at risk practices have declined since the first study, risky contact with poultry is still frequent. Improved rates of reporting poultry mortality were observed overall, but reporting to trained village animal health workers decreased by approximately 50%.Although some improvements in human behavior have occurred, there are still areas--particularly with respect to the handling of poultry among children and the proper treatment of poultry and the surrounding household environment--that need to be addressed in public health campaigns. Though there were some differences in the sampling methods of the 2006 and 2007 surveys, our results illustrate the potential to induce considerable, potentially very relevant, behavioral changes over a short period of time.

Improving farmyard poultry production in Africa: Interventions and their economic assessment. Proceedings of a final research coordination meeting

International Nuclear Information System (INIS)

2006-02-01

A major objective of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is to support research projects involving nuclear and related techniques leading to improved animal production in developing countries. Chicken produced on a relatively small scale, at the farmyard level, are an important source of animal protein for human consumption in developing countries. Limiting factors to maximize this resource include infectious diseases and overall production management. A Coordinated Research Project on Small Scale Poultry Production was initiated in 1998 to evaluate the impact and cost efficacy of inputs in management and veterinary care and provide guidelines to improve the livelihood of farmers. This publication contains the results of the FAO/IAEA Coordinated Research Project entitled Assessment of the Effectiveness of Vaccination Strategies against Newcastle Disease (ND) and Gumboro Disease (IBR) using Immunoassay-based Technologies for Increasing Farmyard Poultry Production in Africa. Thirteen research contract holders in Africa evaluated the major constraints to poultry production in different regions of their countries, analysed the disease situation, management and marketing practises and developed improved ND vaccination and husbandry strategies with the support of the four research agreement holders. This exercise highlighted the added benefit strategic vaccination had on the survival rate and the number of birds produced. A thermostable ND-vaccine seed strain (provided by CSIRO, Australia) reduced the cost of vaccination substantially, as it could be produced locally, with the added advantage of being thermo-resistant, thus reducing the need of a prolonged cool chain. This was further improved by the training of 'village vaccinators' performing vaccine inoculations without the need of veterinary staff on place, insuring vaccination frequency. The efficacy and the level of protection resulting from vaccination were evaluated based on

The consumption of poultry meat and eggs is expected to increase considerably in the nearest future, which creates the demand for new poultry feed ingredients in order to support sustainable intensive production. Moreover, the constant improvement of the genetic potential of poultry has resulted in an increased nutrient density in poultry feeds, which limits the possibility to include low quality feed ingredients. Therefore, the feed industry needs new sources of highly digestible protein wit...

The significance of Campylobacter jejuni infection in poultry: a review.

Science.gov (United States)

Shane, S M

1992-01-01

Campylobacter is a significant cause of enterocolitis in consumers of undercooked poultry meat. Campylobacter jejuni is the most significant of the three thermophilic Campylobacter species, and is responsible for intestinal colonization in poultry and food-borne enteritis in humans. Generally, C. jejuni is apathogenic in poultry, although newly hatched chicks and turkeys may develop a transient diarrhoea following infection. Modern intensive poultry production favours the introduction of infection into commercial growing units, resulting in intestinal colonization during the second to fourth weeks inclusive. Routes of infection include contaminated fomites, infected water supply, rodents, insects, and free-living birds. Vertical transmission is considered unlikely. Contamination of poultry meat is enhanced by deficiencies in transport and processing of broilers and turkeys. Scalding, defeathering and evisceration represent the significant points of cross-contamination during processing. Epidemiological correlation has been established between consumption of contaminated chicken and outbreaks of human campylobacteriosis. Amelioration of infection by application of improved standards of hygiene and decontamination is possible in the context of commercial poultry production. Improvement in washing of carcasses, and the application of chemical disinfectants and gamma irradiation have the potential to reduce the prevalence of C. jejuni contamination in poultry meat. These innovations, together with improved storage and handling of meat products, will reduce the risk of campylobacteriosis to consumers.

Feeding and breeding in conventional production are emerged some of the negative effects and also it is more in organic production with new restrictions. Organic production is based on animal welfare. On the basis of behaviors such as feather-pecking and cannibalism known to be low in protein level of rations and unbalanced in terms of amino acids or minerals. As of 2015, organic poultry feed provided the appropriate conditions that will be 95% organic certified in Turkey and therefore, to create a balanced ration and feed hygiene in protecting brings serious challenges. Fodder supply of organic poultry feed raw materials that make up the quality, quantity and issue forms a significant effect on the health of the poultry additives permitted. The quality of the feed raw materials that constituent diets, quantity, feed supplying form and permitted feed additives significantly affects the health of poultry. Different physiological stages of the animal's nutritional requirements in order to ensure production of quality poultry products must be met from organically produced and very well-known with the contents of feedstuff digestibility. In this study, the problems encountered in feeding can be eliminated while performing economic production with considering animal welfare, following that balanced and adequate organic ration formulations and issues such as improving the production of feed raw materials are discussed.

Aspergillus fumigatus in Poultry

Directory of Open Access Journals (Sweden)

Pascal Arné

2011-01-01

Full Text Available Aspergillus fumigatus remains a major respiratory pathogen in birds. In poultry, infection by A. fumigatus may induce significant economic losses particularly in turkey production. A. fumigatus develops and sporulates easily in poor quality bedding or contaminated feedstuffs in indoor farm environments. Inadequate ventilation and dusty conditions increase the risk of bird exposure to aerosolized spores. Acute cases are seen in young animals following inhalation of spores, causing high morbidity and mortality. The chronic form affects older birds and looks more sporadic. The respiratory tract is the primary site of A. fumigatus development leading to severe respiratory distress and associated granulomatous airsacculitis and pneumonia. Treatments for infected poultry are nonexistent; therefore, prevention is the only way to protect poultry. Development of avian models of aspergillosis may improve our understanding of its pathogenesis, which remains poorly understood.

Full Text Available Energy audit of three poultry processing plants was conducted in southwestern Nigeria. The plants were grouped into three different categories based on their production capacities. The survey involved all the five easily defined unit operations utilized by the poultry processing industry and the experimental design allowed the energy consumed in each unit operation to be measured. The results of the audit revealed that scalding & defeathering is the most energy intensive unit operation in all the three plant categories, averagely accounting for about 44% of the total energy consumption in the processing plants. Other processing operations consuming energy in the following order are eviscerating (17.5%, slaughtering (17%, washing & chilling (16% and packing (6%. The results of the study clearly indicated that the least mechanized of the plants consumed the highest energy (50.36 MJ followed by the semi-mechanized plant (28.04 MJ and the most mechanized plant (17.83 MJ. The energy audits have provided baseline information needed for carrying out budgeting, forecasting energy requirements and planning plant expansion in the poultry processing industries in the study area.

Family poultry production in Mauritius: problems and prospects

International Nuclear Information System (INIS)

Jugessur, V.S.; Seenevassen Pillay, M.M.

2002-01-01

The Republic of Mauritius has been self-sufficient in poultry meat and eggs for more than two decades and has been successfully meeting the increasing demand for these commodities. About 85% of the poultry meat is presently produced by four industrial farms, 10% by small commercial producers, and around 5% by family (backyard) poultry farms. The flourishing broiler production industry has transformed the erstwhile important traditional backyard poultry farming of indigenous chickens into an insignificant side activity on the main island of Mauritius, while on the other hand, scavenging chickens continue to be an important source of both food and income on Rodrigues, the second biggest island territory of the Republic. A survey carried out on 30 selected family poultry farms in Mauritius and Rodrigues in 1999 and 2000 enabled the identification of the major problems faced by smallholder poultry farmers. At the same time the results provided a basis for future interventions for improving family poultry production. The results showed that diseases like fowl pox, Newcastle disease, Gumboro disease, respiratory and parasitic diseases occurred all year round on 42% and 82% of farms in Mauritius and Rodrigues, respectively. Low to mild helminth and lice infestations were detected on 40% and 50% of the farms in Mauritius and Rodrigues, respectively. (author)

Full Text Available Poultry production in eastern Croatia is developed by individual producers mainly in semi intensive way, and within the organized poultry systems where the process is organized in a modern, intensive way. There is a tradition of breeding hens and geese in this area. Poultry products - meat and eggs are important in supplying the population with animal protein, minerals and vitamins. Modern hybrid hens are used for egg production and for meat production in the intensive production. Today geese breeding in these areas are completely neglected. Croatia as a member of European Union, has possibility of the placement of autochthonous breeds of poultry such as Hrvatica hen, Zagorje turkey and Podravian goose. Financial supports at the national level are allocated for the first two autochthonous breeds of poultry because these breeds can, with good production traits, represent genetic resources and strategic reserves in the future development of domestic poultry genotypes. Poultry production is especial emphasis in accordance with the criteria of welfare and health of poultry. This paper discusses further development of poultry in terms of production of poultry meat and eggs as a functional food. The composition and content of nutricines in meat and eggs can be affected by feed composition. Desired nutricines are installed in muscular tissue of poultry by using feed and adding some components. Consumption of eggs and poultry meat enriched by selenium, lutein and omega-3 fatty acids affects the improvement of the quality of the human diet. The recent researches show that chicken can effectively be enriched in carnosine - ingredients that are now taught as “anti-aging” factor. Enrichment of poultry products with nutricines gives greater importance to these foods in the diet of the population than the former one, mainly based on the nutritional aspect. Greater selection of quality poultry products can be a significant factor in the development of

A R Setioko

2008-06-01

Full Text Available Indonesia has abundantly available genetic potential of local poultry that needs to be conserved for future use of poultry development. Live conservation of poultry, both in-situ and ex-situ, would be very expensive and has a risk of mortality due to diseases such as avian influenza. Cryopreservation of Primordial Germ Cells (PGCs, which are progenitor of eggs and spermatozoa, provides an alternative way to preserve both male and female genetic materials in poultry. PGCs in poultry can be specifically harvested from blatoderm or blood embryo, and preserved in a liquid nitrogen similar to sperm, ovum and embryo in large ruminant. Technique for producing germline chimeric chicken has been established by transferring PGCs into the circulated blood embryo where the original PGCs have been removed or inactivated. Mating of germline chimeras yields offsprings that are derived entirely from the donor stock. Conservation of genetic materials of Indonesian indigenous poultry through preservation of PGCs could be used for future poultry improvement.

Muscle growth and poultry meat quality issues.

Science.gov (United States)

Petracci, Massimiliano; Cavani, Claudio

2012-01-01

Over the past 50 years the worldwide growing demand of poultry meat has resulted in pressure on breeders, nutritionists and growers to increase the growth rate of birds, feed efficiency, size of breast muscle and reduction in abdominal fatness. Moreover, the shift toward further processed products has emphasized the necessity for higher standards in poultry meat to improve sensory characteristics and functional properties. It is believed that genetic progress has put more stress on the growing bird and it has resulted in histological and biochemical modifications of the muscle tissue by impairing some meat quality traits. The most current poultry meat quality concerns are associated with deep pectoral muscle disease and white striping which impair product appearance, and increased occurrence of problems related with the meat's poor ability to hold water during processing and storage (PSE-like condition) as well as poor toughness and cohesiveness related to immaturity of intramuscular connective tissue. This paper is aimed at making a general statement of recent studies focusing on the relationship between muscle growth and meat quality issues in poultry.

Mycotoxins in poultry production

Directory of Open Access Journals (Sweden)

Resanović Radmila M.

2009-01-01

Full Text Available All poultry is sensitive to mycotoxins. This partly depends on the type, age and production categories of poultry, their living conditions and nutritive status and partly on the type, quantity and duration of mycotoxin ingestion. The presence of mycotoxins results in significant health disorders and a decrease in production performances. This leads to considerable economic loss for the poultry industry - either direct losses, i.e. death of the poultry or the indirect ones, i.e. the decrease in body mass, number and quality of eggs, greater food conversion, and immunosuppression. Immunosuppression results in increased sensitivity to infective agents and a bad vaccinal response. Morevover, mycotoxin residues in poultry meat, eggs and products derived from them pose a threat to human health. In order to prevent and reduce the negative implications of mycotoxins in the poultry production, it is necessary to create both global and national strategies for combatting mycotoxins, advance diagnostic techniques and procedures, intensify the control of food quality, introduce new limits on the maximum amount of mycotoxins allowed in food and poultry feed used for certain species and categories of animals, and synchronise it with the European standards.

The development of antibiotic resistant pathogens has resulted from the use of sub-therapeutic concentrations of antibiotics delivered in poultry feed. Furthermore, there are a number of consumer concerns regarding the use of antibiotics in food animals including residue contamination of poultry products and antibiotic resistant bacterial pathogens. These issues have resulted in recommendations to reduce the use of antibiotics as growth promoters in livestock in the United States. Unlike conventional production, organic systems are not permitted to use antibiotics. Thus, both conventional and organic poultry production need alternative methods to improve growth and performance of poultry. Herbs, spices, and various other plant extracts are being evaluated as alternatives to antibiotics and some do have growth promoting effects, antimicrobial properties, and other health-related benefits. This review aims to provide an overview of herbs, spices, and plant extracts, currently defined as phytobiotics as potential feed additives. © 2015 Poultry Science Association Inc.

Risk factors for infectious diseases in backyard poultry farms in the Poyang Lake area, China.

Directory of Open Access Journals (Sweden)

Yong Wang

Full Text Available Emergence and transmission of infectious diseases have an enormous impact on the poultry industry and present a serious threat to the health of humans and wild birds. Noncommercial poultry operations, such as backyard poultry facilities in China, are potential sources of virus exchange between commercial poultry and wild birds. It is particularly critical in wetland areas where backyard poultry have close contact with commercial poultry and migratory birds, therefore increasing the risk of contracting infectious diseases. To evaluate the transmission risks, a cross-sectional study was undertaken in the Poyang Lake area, China, involving 309 residents in the backyard poultry farms in three counties (Region A, B, and C of Jiangxi Province. We examined the backyard poultry population, poultry species, presence of poultry deaths from infectious diseases, food sources, and biosecurity practices. Region B ranked highest for biosecurity while region C ranked lowest. The risks of infectious diseases were assessed by adjusted odds ratio based on multivariate logistic regression analysis. Potential risk factors in the three regions of the study site were compared. In Region A, significant factor was contact of poultry with wild birds (OR: 6.573, 95% CI: 2.148-20.115, P=0.001. In Region B, the most significant factor was contact of poultry with neighboring backyard waterfowls (OR: 3.967, 95% CI: 1.555-10.122, P=0.004. In Region C, significant factors were poultry purchase from local live bird markets (OR: 3.740, 95% CI: 1.243-11.255, P=0.019, and contact of poultry with wild birds (OR: 3.379, 95% CI: 1.058-10.791, P=0.040. In summary, backyard poultry was significantly affected by neighboring commercial poultry and close contact with wild birds. The results are expected to improve our understanding of the transmission risks of infectious diseases in a typical backyard poultry environment in rural China, and address the need to improve local farming

Global restriction of using antibiotic growth promoters and alternative strategies in poultry production.

A growing global concern of antibiotic use in poultry diets due to its potential adverse effects on birds and human health, food safety and the environment has led to a complete ban or restricted use in some countries, and, at the same time, expanding options for the use of alternative feed additives. Multiple, rather than a single additive may replace antibiotic growth promoters (AGPs) in poultry. Blending of feeding additives and hygienic farm management, vaccination and biosecurity may help achieve good intestinal health, stabilise enteric ecosystems and result in sustainable and cost effective production performance of birds. Moreover, controlling unsolicited ingredients at the production level must have the support of different markets responsible for the supply of safe and quality poultry products for consumers. This requires the further increase and diversification of value added poultry products and the expansion of their markets through strategic planning and gradual limitation of live bird markets. More research is warranted in order to explore suitable, reliable and cost effective alternatives to AGPs for commercial use, and strategic poultry value chain development.

Transfer of arsenic from poultry feed to poultry litter: A mass balance study.

2018-07-15

Roxarsone (rox), an arsenic (As) containing organic compound, is a common feed additive used in poultry production. To determine if As present in rox is excreted into the poultry litter without any retention in chicken meat for safe human consumption, the transference of As from the feed to poultry excreta was assessed using two commercial chicken strains fed with and without dietary rox. The results revealed that both the strains had similar behaviour in growth (chicken weight; 2.17-2.25kg), feed consumption (282-300kgpen -1 initially containing 102 chicken) and poultry litter production (73-81kgpen -1 ) during the growth phase of 35days. Our mass balance calculations showed that chickens ingested 2669-2730mg As with the feed and excreted out 2362-2896mg As in poultry litter during the growth period of 28days when As containing feed was used, yielding As recovery between 86 and 108%. Though our complementary studies show that residual arsenic species in rox-fed chicken meat may have relevance to human exposure, insignificant retention of total As in the chicken meat substantiates our mass balance results. The results are important in evaluating the fate of feed additive used in poultry production and its potential environmental implications if As containing poultry litter is applied to soil for crop production.

By the year 2010, Italy could see the construction of three incinerators that use poultry manure as source of energy. In this paper, advantages and disadvantages of such a choice are considered in their environmental and economical aspects, taking into account the agronomic qualities of poultry manure. The analyses suggests that the agricultural sector should be the one to recover the biomass. It should be used above all as a fertiliser, either directly or after proper treatments improving its agronomic characteristics. Conversely, the energy sector should be in charge of dismissing the eventual surplus through incineration [it

Combustion studies of poultry litter alone or mixed with peat by 50% on weight basis were undertaken in an atmospheric bubbling fluidised bed. Because of high moisture content of poultry litter, there was some uncertainty whether the combustion could be sustained on 100% poultry litter and as peat is very available in Ireland, its presence was considered to help to improve the combustion. However, the results showed that, as long as the moisture content of poultry litter was kept below 25%, the combustion did not need the addition of peat. The main parameters that were investigated are (i) moisture content, (ii) air staging, and (iii) variations in excess air levels along the freeboard. The main conclusions of the results are (i) combustion was influenced very much by the conditions of the fuel supply, (ii) the steady fuel supply was strongly dependent on the moisture content of the poultry litter, (iii) temperature appeared to be still very influential in reducing the levels of unburned carbon and hydrocarbons released from residues, (iv) the air staging in the freeboard improved combustion efficiency by enhancing the combustion of volatiles released from residues in the riser and (vi) NOx emissions were influenced by air staging in the freeboard. Particles collected from the bed and the two cyclones were analysed to determine the levels of heavy metals and the leachability tests were carried out with ashes collected to verify whether or not they could safely be used in agricultural lands. 8 refs., 1 fig., 8 tabs.

In Kenya the poultry population is about 25 million, 80% of which comprises local chicken and the rest, improved breeds. With the ever-increasing prices of red meat, local chicken has become the main source of animal protein in the form of meat and eggs for the rural population. Both egg production and egg size varies with season as the quantity and availability of feed varies. This paper describes work done during the wet season to identify constraints of family chicken production in the study area. The study was repeated on the same farms that were identified in work done earlier during the dry season. Data were gathered from 24 family poultry farms located in Kangundo and Kikuyu divisions. Through the Veterinary Officers and the Animal Health Assistants who assisted in the dry season fieldwork the farmers were contacted a week before the intended f m visits. Baseline and disease survey forms were administered again. The baseline survey achieved 100% response rate. During the farm visits, serum samples, blood and faecal samples were collected. Post mortem examination was also done on sick birds. The flock size in the two ecological zones decreased during the wet season, most probably due to the Christmas festivities. The percentage deaths in Ecological Zone III (ECZIII) were high because most farmers in this zone set their chicken free thus predisposing them to predators, disease and harsh weather conditions. Disease control information was scanty as most farmers were not keen about it. Worm infestation was not as prevalent in the wet season as compared to the dry season. Except for three farms, all the other twenty-one farms had been exposed to Salmonellosis at one time or another. Women were involved in aspects of poultry management, while the men were significantly involved in shelter construction. The local birds were free-range feeding on green grass, leafy vegetables and insects. Occasionally, the birds were supplemented with crushed maize grains or

2017-06-01

As pastured poultry production has gained increased popularity in the United States in recent years, there is a growing need for research and outreach efforts aimed at this sector of poultry production. In order to get familiarized with American pastured poultry producers, we conducted an online questionnaire aimed primarily at evaluating what operational challenges are faced by producers and what educational opportunities should be initiated by researchers. Results showed that pastured poultry farms largely vary in total number of acres farmed and total number of birds kept. The vast majority of farms (96%) rotate their flocks on pasture and include livestock species (78%) in their rotation systems. Mobile coops are the preferred housing option provided by producers (88%). The most common source of mortality listed by respondents was predation (52%), followed by "other" (32%). However, predation was not selected as the most important challenge by the majority of respondents. Sixty-four percent of participants instead mentioned providing adequate feed at reasonable cost as the major challenge in raising poultry on pasture, followed again by "other" (52%) and lack of processing facilities for small numbers of birds (40%). Finally, the topics considered by respondents as the most helpful to learn more about were how to improve egg production rate and/or feed conversion ratio (67%), followed by how to improve pasture condition and optimum vegetative cover all year round (62%). Despite its small sample size, this study's results provide some valuable insights of challenges encountered and information needed on pastured poultry farms. © 2017 Poultry Science Association Inc.

Biosecurity Assessment and Seroprevalence of Respiratory Diseases in Backyard Poultry Flocks Located Close to and Far from Commercial Premises.

Raising backyard chickens is an ever-growing hobby in the United States. These flocks can be a substrate for respiratory disease amplification and transmission to commercial facilities. Five hundred fifty-four chickens from 41 backyard flocks were sampled in this study. ELISA kits were used to detect antibodies against avian influenza (AI), infectious laryngotracheitis (ILT), Newcastle disease (ND), infectious bronchitis (IB), Ornithobacterium rhinotracheale (ORT), Mycoplasma gallisepticum (MG), and Mycoplasma synoviae (MS). All visited flock owners answered a biosecurity questionnaire that assessed biosecurity measures. The questionnaire revealed that backyard poultry owners lack simple biosecurity measures such as use of dedicated shoes, their chicken sources are unreliable, and few of them benefit from veterinary oversight. Only one flock had a clear vaccination history against ND and IB. ORT, ND, IB, MS, MG, and ILT were the most seroprevalent in backyard poultry flocks with 97% (41/42), 77.5% (31/40), 75% (30/40), 73% (31/42), 69% (29/42), and 45% (19/42), respectively. The vaccinated flock was not considered in these calculations. When examining the distance between backyard flocks and the nearest commercial poultry facility, ND and MG were significantly more likely to be found in backyard flocks close to (4 miles) commercial poultry. Birds purchased directly from National Poultry Improvement Plan hatcheries showed a reduced ND, MG, and MS antibody prevalence. Wearing dedicated shoes decreased MS antibody-positive birds. Finally, history of wild bird contact had a clear effect on an increased seroprevalence of NDV and MG. Serological results suggest that backyard poultry flocks have the potential to serve as a reservoir or amplifier for poultry respiratory diseases. The information generated in this project should direct extension efforts toward emphasizing the importance of small flock biosecurity and chick acquisition sources.

Poultry is commonly raised by households in rural Bangladesh. In 2007, the Government of Bangladesh began a mass media campaign to disseminate 10 recommended precautions to prevent transmission of H5N1 from poultry to humans. This longitudinal study explored the contribution of backyard poultry on household economy and nutrition and compared poultry-raising practices to government recommendations. From 2009 to 2012, we enrolled a nationally representative sample of 2489 primary backyard poultry raisers from 115 rural villages selected by probability proportional to population size. Researchers interviewed the raisers to collect data on poultry-raising practices. They followed the raisers for 2-12 months to collect data on household income and nutrition from poultry. Income from backyard poultry flocks accounted for 2.8% of monthly household income. Return on annual investment (ROI) per flock was 480%. Yearly, median family consumption of eggs was one-fifth of the total produced eggs and three poultry from their own flock. Respondents' reported practices conflicted with government recommendations. Sixty per cent of raisers had never heard of avian influenza or 'bird flu'. Among the respondents, 85% handled sick poultry or poultry that died due to illness, and 49% slaughtered or defeathered sick poultry. In 37% of households, children touched poultry. Fifty-eight per cent never washed their hands with soap after handling poultry, while poultry. Only 3% reported poultry illness and deaths to local authorities. These reported practices did not improve during the study period. Raising backyard poultry in rural Bangladesh provides important income and nutrition with an excellent ROI. Government recommendations to reduce the risk of avian influenza transmission did not impact the behaviour of poultry producers. Further research should prioritize developing interventions that simultaneously reduce the risk of avian influenza transmission and increase productivity of

Organic poultry is an alternative to conventional poultry which is rapidly developing as a response to customers' demand for better food and a cleaner environment. Although organic poultry manure can partially be utilized by organic horticultural producers, litter accumulation as well as excessive nitrogen still remains a challenge to maintain environment pureness, animal, and human health. Compared to conventional poultry, diet formulation without nitrogen overloading in organic poultry is even more complicated due to specific standards and regulations which limit the application of some supplements and imposes specific criteria to the ingredients in use. This is especially valid for methionine provision which supplementation as a crystalline form is only temporarily allowed. This review is focused on the utilization of various protein sources in the preparation of a diet composed of 100% organic ingredients which meet the avian physiology need for methionine, while avoiding protein overload. The potential to use unconventional protein sources such as invertebrates and microbial proteins to achieve optimal amino acid provision is also discussed.

Developing control points for halal slaughtering of poultry.

Shahdan, I A; Regenstein, J M; Shahabuddin, A S M; Rahman, M T

2016-07-01

Halal (permissible or lawful) poultry meat production must meet industry, economic, and production needs, and government health requirements without compromising the Islamic religious requirements derived from the Qur'an and the Hadiths (the actions and sayings of the Prophet Muhammad, peace and blessings be upon him). Halal certification authorities may vary in their interpretation of these teachings, which leads to differences in halal slaughter requirements. The current study proposes 6 control points (CP) for halal poultry meat production based on the most commonly used halal production systems. CP 1 describes what is allowed and prohibited, such as blood and animal manure, and feed ingredients for halal poultry meat production. CP 2 describes the requirements for humane handling during lairage. CP 3 describes different methods for immobilizing poultry, when immobilization is used, such as water bath stunning. CP 4 describes the importance of intention, details of the halal slaughter, and the equipment permitted. CP 5 and CP 6 describe the requirements after the neck cut has been made such as the time needed before the carcasses can enter the scalding tank, and the potential for meat adulteration with fecal residues and blood. It is important to note that the proposed halal CP program is presented as a starting point for any individual halal certifying body to improve its practices. © 2016 Poultry Science Association Inc.

In the last two decades, two important avian influenza viruses infecting humans emerged in China, the highly pathogenic avian influenza (HPAI) H5N1 virus in the late nineties, and the low pathogenic avian influenza (LPAI) H7N9 virus in 2013. China is home to the largest population of chickens (4.83 billion) and ducks (0.694 billion), representing, respectively 23.1 and 58.6% of the 2013 world stock, with a significant part of poultry sold through live-poultry markets potentially contributing to the spread of avian influenza viruses. Previous models have looked at factors associated with HPAI H5N1 in poultry and LPAI H7N9 in markets. However, these have not been studied and compared with a consistent set of predictor variables. Significant progress was recently made in the collection of poultry census and live-poultry market data, which are key potential factors in the distribution of both diseases. Here we compiled and reprocessed a new set of poultry census data and used these to analyse HPAI H5N1 and LPAI H7N9 distributions with boosted regression trees models. We found a limited impact of the improved poultry layers compared to models based on previous poultry census data, and a positive and previously unreported association between HPAI H5N1 outbreaks and the density of live-poultry markets. In addition, the models fitted for the HPAI H5N1 and LPAI H7N9 viruses predict a high risk of disease presence for the area around Shanghai and Hong Kong. The main difference in prediction between the two viruses concerned the suitability of HPAI H5N1 in north-China around the Yellow sea (outlined with Tianjin, Beijing, and Shenyang city) where LPAI H7N9 has not spread intensely.

Women and family poultry production in rural Africa.

Science.gov (United States)

Gueye, E H

2000-02-01

Poultry production has existed for many generations in Africa, and almost every village household keeps chickens. The rural family poultry (RFP) are generally raised in free-range and/or backyard systems, which are traditional extensive husbandry systems. The development of an intensive poultry production has been the goal of the African government over the years. Despite efforts aiming for such goal, RFP is still very important in African countries that are both poor and net importers of food. It is a valuable asset because it can contribute significantly in alleviating poverty, securing food supply, and promoting gender equality. In view of this, interventions to improve RFP production systems should take into account the sociocultural issues, specifically gender-based aspects. It is noted that such interventions might, in addition to food security and poverty alleviation, also serve to promote gender equality. RFP development programs should be more women-friendly in order to facilitate women's participation, as RFP production in the region is generally a woman's business. Moreover, efforts to empower village women has to be envisaged cautiously as there is a serious risk of men taking over once the poultry sector becomes more profitable.

Risk perceptions of public health and food safety hazards in poultry husbandry by citizens, poultry farmers and poultry veterinarians

2018-01-01

Abstract Differences in risk perceptions of public health and food safety hazards in various poultry husbandry systems by various stakeholder groups, may affect the acceptability of those husbandry systems. Therefore, the objective was to gain insight into risk perceptions of citizens, poultry farmers, and poultry veterinarians regarding food safety and public health hazards in poultry husbandry systems, and into factors explaining these risk perceptions. We surveyed risk perceptions of Campylobacter contamination of broiler meat, avian influenza introduction in laying hens, and altered dioxin levels in eggs for the most commonly used broiler and laying hen husbandry systems in Dutch citizens (n = 2,259), poultry farmers (n = 100), and poultry veterinarians (n = 41). Citizens perceived the risks of the three hazards in the indoor systems higher and in the outdoor systems lower than did the professionals. Citizens reported higher concerns regarding aspects reflecting underlying psychological factors of risk perception compared to professionals. Professionals indicated a relatively low level of personal control, which might imply risk denial. Of the socio-demographic characteristics, gender and childhood residence were associated with risk perceptions. The influence of other factors of risks perception are discussed. It is suggested that risk perceptions of all stakeholder groups are influenced by affect, stigma, and underlying values. To adapt current or new husbandry systems that can count on societal support, views of key stakeholders and multiple aspects such as animal welfare, public health, food safety, and underlying values should be considered integrally. When trade-offs, such as between animal welfare and public health have to be made, insight into underlying values might help to find consensus among stakeholders. PMID:29161444

Campylobacteriosis: the role of poultry meat.

Science.gov (United States)

Skarp, C P A; Hänninen, M-L; Rautelin, H I K

2016-02-01

The incidence of human infections caused by Campylobacter jejuni and Campylobacter coli, the main bacterial agents of gastrointestinal disease, has been increasing worldwide. Here, we review the role of poultry as a source and reservoir for Campylobacter. Contamination and subsequent colonization of broiler flocks at the farm level often lead to transmission of Campylobacter along the poultry production chain and contamination of poultry meat at retail. Yet Campylobacter prevalence in poultry, as well as the contamination level of poultry products, vary greatly between different countries so there are differences in the intervention strategies that need to be applied. Temporal patterns in poultry do not always coincide with those found in human infections. Studies in rural and urban areas have revealed differences in Campylobacter infections attributed to poultry, as poultry seems to be the predominant reservoir in urban, but not necessarily in rural, settings. Furthermore, foreign travel is considered a major risk factor in acquiring the disease, especially for individuals living in the northern European countries. Intervention strategies aimed at reducing Campylobacter colonization in poultry and focused at the farm level have been successful in reducing the number of Campylobacter cases in several countries. Increasing farm biosecurity and education of consumers are likely to limit the risk of infection. Overall, poultry is an important reservoir and source of human campylobacteriosis, although the contribution of other sources, reservoirs and transmission warrants more research.

Greenhouse gas mitigation using poultry litter management techniques in Bangladesh

International Nuclear Information System (INIS)

Mainali, Brijesh; Emran, Saad Been; Silveira, Semida

2017-01-01

Poultry activities have expanded significantly in Bangladesh in recent years. The litter generated from rural poultry farms is often dumped in low ground neighboring areas resulting in greenhouse gas emissions, as well as water and air pollution. This study estimates the GHG emissions of a typical rural layer poultry farm in Bangladesh, and identifies the GHG emissions reduction potential when poultry litter management techniques are used to produce biogas, generating electricity and bio-fertilizer. Life-cycle assessment (LCA) has been used for a systematic evaluation of GHG-emissions considering the local supply chain in a typical rural layer poultry farm. The analysis shows that the GHG-emissions at the poultry farm amount to 1735 KgCO_2_e_q/10000 eggs produced if the litter is untreated. With the installation of an anaerobic digester, the emission intensity could be reduced by 65% if the gas is used to replace LPG for cooking purposes. If 100% digested slurry is utilized as bio-fertilizer, the emissions intensity could be further reduced by 17 times compared to the case without slurry utilization. These results justify the consideration of national programs to improve conditions in poultry farms in Bangladesh. - Highlights: • This study estimates GHG-emissions reduction potential of utilizing poultry litter for energy production in a rural farm. • Energy/mass flow and GHG balances are evaluated considering the local supply chain. • On-farm activities significantly affect GHG emissions among others across the supply chain. • Biogas production and use of slurry as bio-fertilizer significantly reduces the emission intensity. • Results from LCA and sensitivity analysis have been discussed to identify key influential parameters.

Full Text Available Aim. The aim is to study the effect of bactericidal installation in combination with a device for creating a water curtain on the microclimate in the poultry house and environment. Methods. Epizootic research was carried out according to "epizootic methodology", FGI «Federal Centre for Animal Health» (FGI «ARRIAH». Gas composition of air was investigated by means of universal gas-analyzer (UG-2; the content of carbon dioxide was measured by Subbotin-Nagorskiy titrimetric method; the amount of dust in the air was measured by a gravimetric (weight method. Air humidity was calculated by means of August statistical psychrometer. Evaluation of the microbial contamination of air was carried out using the Krotov’s device. Results. The performed studies before and after the air bactericidal purification in a poultry farm showed a reduction of carbon dioxide and ammonia by 2-2.5 times, the total microbial contamination of air by 1.9 times and the dust by 4.3 times. We found a direct link between the increases in the amount of microbial bodies of air depending on the age of the bird. Thus, after air-cleaning in the poultry house room where they kept 15-d-old chicks, we calculated 5 thousand microbial cells per one m3 found (E.coli, and at the age of 45 days, the level of contamination reached 11 thousand microbial bodies. Conclusion. Research in the poultry house reveals that using bactericidal installation paired with water curtain device can significantly reduce the concentration of gases, dust and microorganisms in the air of the house and decrease the release into the environment, which will undoubtedly have an impact on the ecological situation of the environment, animal and human health.

Use of essential oils in poultry nutrition: A new approach

Directory of Open Access Journals (Sweden)

Gopal Krishan

2014-12-01

Full Text Available Emergence of antibiotic resistant bacteria has created the necessity of replacement of antibiotic with other products like prebiotics, probiotics, organic acid botanicals, and herbal essential oils. Essential oils (EOs are important aromatic components of herbs and spices, and are used as natural alternatives for replacing antibiotic growth promoters (AGPs in poultry feed as these have antimicrobial, antifungal, antiparasitic, and antiviral properties. Beside, other beneficial effects of EOs include appetite stimulation, improvement of enzyme secretion related to food digestion, and immune response activation. Recently, use of EOs in broiler chickens has drawn attentions. EOs are generally used as blend with a carrier oil or combination with other plant oils in the feed to enhance the productive performance of birds. Conclusively, EOs can be used in poultry feed, but there are still questions concerning their action, metabolic pathway and optimal dosage in poultry, which are to be explored in detail. This mini-review describes the expanding horizons in the research on EOs in poultry nutrition.

Contacts between poultry farms, their spatial dimension and their relevance for avian influenza preparedness

Directory of Open Access Journals (Sweden)

Lena Fiebig

2009-11-01

Full Text Available Ongoing economic losses by and exposure of humans to highly pathogenic avian influenza (HPAI in poultry flocks across Asia and parts of Africa and Europe motivate also outbreak-free countries such as Switzerland to invest in preparedness planning. Country-specific population data on between-farm contacts are required to anticipate probable patterns of pathogen spread. Information is scarce; in particular on how strongly small, non-commercial poultry farms are involved in between-farm contacts. We aimed to identify between-farm contacts of interest for HPAI spread at both commercial and non-commercial farms in a non-outbreak situation: whether or not commercial and non-commercial farms were involved in poultry and person movements and shared resources by company integration. Focus was on poultry movements for the purpose of purchase, sale and poultry show visits, their spatial dimension, their frequencies and the farm types they connected. Of the total 49,437 recorded poultry farms in Switzerland, 95% had less than 500 birds. The farm number resulted in densities of up to 8 poultry farms per km2 and a median number of 47 neighbour farms within a 3 km radius around the farms. Person movements and shared resources were identified in 78% of the surveyed farms (93% among commercials, 67% among non-commercials. Poultry trading movements over extensive spatial ranges were stated at 65% (79% among commercials, 55% among non-commercials. Movement frequencies depended on farm specialization and were higher for commercial than for non-commercial farms except for poultry show visits. Estimates however for the entire population revealed 3.5 times higher chances of a poultry purchase, and 14.6 times higher chances of exhibiting birds at poultry shows occurring in a given time by a farm smaller than 500 birds (non-commercial farm than by a larger (commercial farm. These findings indicate that both commercial and non-commercial farms are involved in

Modeling the burden of poultry disease on the rural poor in Madagascar

Directory of Open Access Journals (Sweden)

Cassidy L. Rist

2015-12-01

Full Text Available Livestock represent a fundamental economic and nutritional resource for many households in the developing world; however, a high burden of infectious disease limits their production potential. Here we present an ecological framework for estimating the burden of poultry disease based on coupled models of infectious disease and economics. The framework is novel, as it values humans and livestock as co-contributors to household wellbeing, incorporating feedbacks between poultry production and human capital in disease burden estimates. We parameterize this coupled ecological–economic model with household-level data to provide an estimate of the overall burden of poultry disease for the Ifanadiana District in Madagascar, where over 72% of households rely on poultry for economic and food security. Our models indicate that households may lose 10–25% of their monthly income under current disease conditions. Results suggest that advancements in poultry health may serve to support income generation through improvements in both human and animal health.

Irradiation and additive combinations on the pathogen reduction and quality of poultry meat.

Science.gov (United States)

Ahn, Dong U; Kim, Il Suk; Lee, Eun Joo

2013-02-01

Reduction of foodborne illnesses and deaths by improving the safety of poultry products is one of the priority areas in the United States, and developing and implementing effective food processing technologies can be very effective to accomplish that goal. Irradiation is an effective processing technology for eliminating pathogens in poultry meat. Addition of antimicrobial agents during processing can be another approach to control pathogens in poultry products. However, the adoption of irradiation technology by the meat industry is limited because of quality and health concerns about irradiated meat products. Irradiation produces a characteristic aroma as well as alters meat flavor and color that significantly affect consumer acceptance. The generation of a pink color in cooked poultry and off-odor in poultry by irradiation is a critical issue because consumers associate the presence of a pink color in cooked poultry breast meat as contaminated or undercooked, and off-odor in raw meat and off-flavor in cooked meat with undesirable chemical reactions. As a result, the meat industry has difficulties in using irradiation to achieve its food safety benefits. Antimicrobials such as sodium lactate, sodium diacetate, and potassium benzoate are extensively used to extend the shelf-life and ensure the safety of meat products. However, the use of these antimicrobial agents alone cannot guarantee the safety of poultry products. It is known that some of the herbs, spices, and antimicrobials commonly used in meat processing can have synergistic effects with irradiation in controlling pathogens in meat. Also, the addition of spices or herbs in irradiated meat improves the quality of irradiated poultry by reducing lipid oxidation and production of off-odor volatiles or masking off-flavor. Therefore, combinations of irradiation with these additives can accomplish better pathogen reduction in meat products than using them alone even at lower levels of antimicrobials/herbs and

Nuclear Station Facilities Improvement Planning

International Nuclear Information System (INIS)

Hooks, R. W.; Lunardini, A. L.; Zaben, O.

1991-01-01

An effective facilities improvement program will include a plan for the temporary relocation of personnel during the construction of an adjoining service building addition. Since the smooth continuation of plant operation is of paramount importance, the phasing plan is established to minimize the disruptions in day-to-day station operation and administration. This plan should consider the final occupancy arrangements and the transition to the new structure; for example, computer hookup and phase-in should be considered. The nuclear industry is placing more emphasis on safety and reliability of nuclear power plants. In order to do this, more emphasis is placed on operations and maintenance. This results in increased size of managerial, technical and maintenance staffs. This in turn requires improved office and service facilities. The facilities that require improvement may include training areas, rad waste processing and storage facilities, and maintenance facilities. This paper discusses an approach for developing an effective program to plan and implement these projects. These improvement projects can range in magnitude from modifying a simple system to building a new structure to allocating space for a future project. This paper addresses the planning required for the new structures with emphasis on site location, space allocation, and internal layout. Since facility planning has recently been completed by Sargent and Leyden at six U. S. nuclear stations, specific examples from some of those plants are presented. Site planning and the establishment of long-range goals are of the utmost importance when undertaking a facilities improvement program for a nuclear station. A plan that considers the total site usage will enhance the value of both the new and existing facilities. Proper planning at the beginning of the program can minimize costs and maximize the benefits of the program

ECONOMETRIC DETERMINATION OF CONTRIBUTION OF FAMILY POULTRY TO WOMEN’S INCOME IN NIGER-DELTA, NIGERIA

Directory of Open Access Journals (Sweden)

R ALABI

2007-07-01

Full Text Available This study shows that family poultry husbandry, business activities and paid employment contribute 35%, 30% and 18% respectively to the household income of women in Niger Delta, Nigeria. The average income from family poultry is N16, 784.53 ($124.33, which is about 25% and 50% of national minimum wage and per capita income in Nigeria respectively. The major constraints to the family poultry in the study area are disease and pest, pilfering and lack of capital. The econometric analysis indicates that wage, business and family poultry income are significant determinants of income of women in the study area. The estimated regression coefficients are, 0.35, 0.32 and 0.19 for wage, business and family poultry income respectively. This suggests that if wage income, business income and family poultry income increase by 100%, total income of the women will increase by 35%, 32% and 19% respectively. This indicates that family poultry husbandry has third rating in potentially influencing women income in the study area. It is recommended from the study that the contribution of family poultry to total income of the women can be improved through proper medication and vaccination of their birds with vaccines that are stable under tropical environment. It is also imperative that semi intensive, if not intensive, rearing technology should be considered as a reasonable option if the problem of pilfering is to be addressed. Improving the capital base of the women through formation of cooperating and micro-credit schemes should also be a welcome development in addressing the problem of lack of capital.

2014-12-01

Fungal contamination of poultry feed causes economic losses to industry and represents a potential risk to animal health. The aim of the present study was to analyze the effectiveness of whey fermented with kefir grains as additive to reduce fungal incidence, thus improving feed safety. Whey fermented for 24 h at 20 °C with kefir grains (100 g L(-1) ) reduced conidial germination of Aspergillus flavus, Aspergillus parasiticus, Aspergillus terreus, Aspergillus fumigatus, Penicillium crustosum, Trichoderma longibrachiatum and Rhizopus sp. Poultry feed supplemented with fermented whey (1 L kg(-1) ) was two to four times more resistant to fungal contamination than control feed depending on the fungal species. Additionally, it contained kefir microorganisms at levels of 1 × 10(8) colony-forming units (CFU) kg(-1) of lactic acid bacteria and 6 × 10(7) CFU kg(-1) of yeasts even after 30 days of storage. Fermented whey added to poultry feed acted as a biopreservative, improving its resistance to fungal contamination and increasing its shelf life. © 2014 Society of Chemical Industry.

Farm Models and Eco-Health of Poultry Production Clusters (PPCs following Avian Influenza Epidemics in Thailand

Worapol Aengwanich

2014-04-01

Full Text Available Thailand is located in Southeast Asia and is a country that was affected by highly pathogenic avian influenza (HPAI epidemics during 2003–2004. Nevertheless, the Thai government’s issuance policy of strict control and prevention of the disease has resulted in efficient disease control of avian influenza (AI. Poultry farmers have been both positively and negatively affected by this policy. There are three poultry cluster models worthy of attention in Thailand: (1 egg chicken poultry clusters over ponds; (2 egg chicken poultry clusters in coops raised from the ground and managed by a cooperative; and (3 poultry clusters in closed coops under contract with the private sector. Following the AI epidemics, additional poultry husbandry and biosecurity systems were developed, thereby generating income and improving the quality of life for poultry farmers. Nevertheless, raising large clusters of poultry in the same area results in disadvantages, particularly problems with both air and water pollution, depending upon the environments of each poultry model. Furthermore, the government’s policy for controlling AI during epidemics has had a negative effect on the relationship between officials and farmers, due to poultry destruction measures.

Biological conversion of poultry and animal waste to a feedstuff for poultry

Energy Technology Data Exchange (ETDEWEB)

El Boushy, A.R.; Klaassen, G.J.; Ketelaars, E.H.

1985-06-01

Poultry and animal waste can be converted into a high protein feed-stuff by biological digestion and degradation, oxidation or by the action of micro-organisms and algae. These processes might help to solve the accummulating problem of disposal of poultry and animal waste, which in some cases are not suitable as soil fertilizers and cause pollution problems. International co-operation between advanced industrialized countries and developing areas is not only desirable but essential to overcome malnutrition by increasing the animal protein supply in the form of meat and eggs. Only a limited number of published data are available but nevertheless five types of treated waste are considered useful under certain conditions as feedstuffs for poultry: 1. housefly pupae meal - caged layer manure degraded by housefly larvae; 2. earthworm meal - another biodegradation of caged layer manure; 3. liquor and residue from a ditch used for oxidizing swine liquid manure; 4. aerobic fermentation of poultry manure; and 5. meals produced from algae grown in ponds of sedimented animal waste and sewage. 46 references.

Beneficial Effects of Poultry Meat Consumption on Cardiovascular Health and the Prevention of Childhood Obesity

Directory of Open Access Journals (Sweden)

Mustafa Metin Donma

2017-08-01

Full Text Available Poultry meat is an animal product important in human nutrition. A variable, and moderate energy content, highly digestible proteins of good nutritional quality, unsaturated lipids, fat-soluble and B-complex vitamins as well as minerals make poultry meat a valuable food. Poultry meat is one of the recommended constituents of Dietary Approaches to Stop Hypertension Diet as well as the Mediterranean Diet. The substitution of red meat with poultry as well as fish, nuts and legumes decreases the risk of developing type 2 and gestational diabetes mellitus, improves glycemic control and cardiovascular risk factors. Low-fat diets supported by fruits, grains, nuts, fish and poultry instead of red meat yields cardiovascular health benefits. Anti-inflammatory and antioxidative diet enriched with high-quality foods reduces pro-inflammatory cytokines. This favors anti-inflammatory milieu which in turn improves insulin sensitivity and endothelial function and ultimately act as a barrier to obesity, metabolic syndrome, type 2 diabetes mellitus and development of atherosclerosis. The nutritive value of poultry meat depends on different factors such as age, feeding, keeping, hybrids, carcass parts and type of meat. Preventive measures against risky aspects of the matter should be developed. Since the use of antibiotics leads to the development of antibiotic resistant pathogens, antibiotics must be replaced by herbs and spices with growth promoting effects, antimicrobial properties, and other health related benefits to solve the problem. Enrichment and fortification with nutrients may cause poultry meat to gain even more functional food character.

Salmonellosis: the role of poultry meat.

Science.gov (United States)

Antunes, P; Mourão, J; Campos, J; Peixe, L

2016-02-01

Salmonellosis remains one of the most frequent food-borne zoonoses, constituting a worldwide major public health concern. Currently, at a global level, the main sources of infection for humans include meat products, including the consumption of contaminated poultry meat, in spite of the success of Salmonella control measures implemented in food-animal production of industrialized countries. In recent years, a shift in Salmonella serotypes related to poultry and poultry production has been reported in diverse geographical regions, being particularly associated with the spread of certain well-adapted clones. Moreover, antimicrobial resistance in non-typhoidal Salmonella is considered one of the major public health threats related with food-animal production, including the poultry production chain and poultry meat, which is an additional concern in the management of salmonellosis. The circulation of the same multidrug-resistant Salmonella clones and/or identical mobile genetic elements encoding antibiotic resistance genes from poultry to humans highlights this scenario. The purpose of this review was to provide an overview of the role of poultry meat on salmonellosis at a global scale and the main problems that could hinder the success of Salmonella control measures at animal production level. With the increasing globalization of foodstuffs like poultry meat, new problems and challenges might arise regarding salmonellosis control, making new integrated intervention strategies necessary along the food chain.

Campylobacter in Poultry: Ecology and Potential Interventions.

Science.gov (United States)

Sahin, Orhan; Kassem, Issmat I; Shen, Zhangqi; Lin, Jun; Rajashekara, Gireesh; Zhang, Qijing

2015-06-01

Avian hosts constitute a natural reservoir for thermophilic Campylobacter species, primarily Campylobacter jejuni and Campylobacter coli, and poultry flocks are frequently colonized in the intestinal tract with high numbers of the organisms. Prevalence rates in poultry, especially in slaughter-age broiler flocks, could reach as high as 100% on some farms. Despite the extensive colonization, Campylobacter is essentially a commensal in birds, although limited evidence has implicated the organism as a poultry pathogen. Although Campylobacter is insignificant for poultry health, it is a leading cause of food-borne gastroenteritis in humans worldwide, and contaminated poultry meat is recognized as the main source for human exposure. Therefore, considerable research efforts have been devoted to the development of interventions to diminish Campylobacter contamination in poultry, with the intention to reduce the burden of food-borne illnesses. During the past decade, significant advance has been made in understanding Campylobacter in poultry. This review summarizes the current knowledge with an emphasis on ecology, antibiotic resistance, and potential pre- and postharvest interventions.

Simulations at Czech poultry market

Directory of Open Access Journals (Sweden)

Lenka Rumánková

2012-01-01

Full Text Available This paper defines the possible scenarios of the development of the poultry market in the Czech Republic, in view of the trends in production, consumption and foreign trade. The individual scenarios are based upon the forecasts of selected factors that have a substantial impact on the poultry market and whose changes can be expected in the subsequent years with great likelihood. The article sets out and addresses various scenarios for the period of 2012–2014. The scenarios are based upon the partial equilibrium model of the poultry market, which has been derived on the basis of time series and panel data within the years 1995–2009. The conducted analysis clearly shows that changes in the prices of agricultural producers will have an effect on changes in the production of poultry meat, an increase in VAT through consumer prices will impact the rate of domestic consumption, as well as changes in disposable income. Similarly, a change in the exchange rate will have an effect on the amount of poultry imported into the Czech Republic.

Effect of Newcastle Disease Control and Improved Management on the Performance of Indigenous Poultry in Western Kenya

International Nuclear Information System (INIS)

Ondwasy, H.O.; Okitoi, L.O.; Obali, M.P.; Mukisira, E.A.; Jong, R.

1999-01-01

indigenous poultry farming is an important enterprise for small-scale farmers in the mandate areas of the Regional Research Centre (RRC) Kakamega, A topical Participatory rural appraisal (PRA) study involving 407 farmers identified the main constraints to rural poultry production in the area as Newcastle disease (NCD), predation, and inadequate feeding or supplementation. The objectives of the study were to evaluate the effects of vaccination against Newcastle disease (NCD), daytime housing for chicks and feed supplementation on indigenous poultry production. The trial was implemented in four RRC clusters, each representing a specific agro-ecological zone.The clusters included Sabatia (UM 1 ), Butula (LM 1 ) Malava (LM 2 ), and Uranga (LM 3 ). Each cluster comprised of 22 to 35 experimental farmers in four groups assigned to the various treatments thus: Group 1 vaccination, 2. vaccination and supplementation, 3. vaccination, supplementation and daytime housing of chicks and 4. control group or farmer's practice. Since farmers adopted treatments according to their preference, the composition of each group varied as the experiment progressed. Birds were vaccinated after every three months to prevent NCD attacks,' To' avoid predation, the chicks were housed in movable or permanent structures where supplements such as brewers waste, blood and rumen contents from slaughterhouses were provided. From January 1997, data was collected weekly from individual households by frontline extension staff. Monthly monitoring and data verification on flock composition and dynamics, eggs production and utilisation, feed use and growth rates, was done by researchers and agricultural extensionists. The results demonstrated that Newcastle disease could be controlled by routine vaccination; feed supplementation improved the performance of housed birds in three clusters, but not in Sabatia where scarcity of feed was pronounced. It was further concluded that predation continued to constrain

Full Text Available The purpose of this paper is to develop a systematic investigation for the serious problems of livestock and poultry breeding in China and the technical demand of promoting the utilization of manure. Based on the status quo of large-scale livestock and poultry farming in typical areas in China, the work had been done beared on statistics and analysis of the modes and proportions of utilization of manure resources. Such a statistical method had been applied to the country -identified large -scale farm, which the total amount of pollutants reduction was in accordance with the "12th Five-Year Plan" standards. The results showed that there were some differences in the modes of resource utilization due to livestock and poultry manure at different scales and types:(1 Hogs, dairy cattle and beef cattle in total accounted for more than 75% of the agricultural manure storage;(2 Laying hens and broiler chickens accounted for about 65% of the total production of the organic manure produced by fecal production. It is demonstrated that the major modes of resource utilization of dung and urine were related to the natural characteristics, agricultural production methods, farming scale and economic development level in the area. It was concluded that the unreasonable planning, lacking of cleansing during breeding, false selection of manure utilizing modes were the major problems in China忆s large-scale livestock and poultry fecal resources utilization.

Human infections with non-typhoidal Salmonella (NTS) serovars are increasingly becoming a threat to human health globally. While all motile Salmonellae have zoonotic potential, Salmonella Enteritidis and Salmonella Typhimurium are most commonly associated with human disease, for which poultry are a major source. Despite the increasing number of human NTS infections, the epidemiology of NTS in poultry in India has not been fully understood. Hence, as a first step, we carried out epidemiological analysis to establish the incidence of NTS in poultry to evaluate the risk to human health. A total of 1215 samples (including poultry meat, tissues, egg and environmental samples) were collected from 154 commercial layer farms from southern India and screened for NTS. Following identification by cultural and biochemical methods, Salmonella isolates were further characterized by multiplex PCR, allele-specific PCR, enterobacterial repetitive intergenic consensus (ERIC) PCR and pulse field gel electrophoresis (PFGE). In the present study, 21/1215 (1.73 %) samples tested positive for NTS. We found 12/392 (3.06 %) of tissue samples, 7/460 (1.52 %) of poultry products, and 2/363 (0.55 %) of environmental samples tested positive for NTS. All the Salmonella isolates were resistant to oxytetracycline, which is routinely used as poultry feed additive. The multiplex PCR results allowed 16/21 isolates to be classified as S. Typhimurium, and five isolates as S. Enteritidis. Of the five S. Enteritidis isolates, four were identified as group D Salmonella by allele-specific PCR. All of the isolates produced different banding patterns in ERIC PCR. Of the thirteen macro restriction profiles (MRPs) obtained by PFGE, MRP 6 was predominant which included 6 (21 %) isolates. In conclusion, the findings of the study revealed higher incidence of contamination of NTS Salmonella in poultry tissue and animal protein sources used for poultry. The results of the study warrants further investigation

The use of inulin in poultry feeding: a review.

Science.gov (United States)

Bucław, M

2016-12-01

Since the European Union enforced the ban on antibiotic growth promoters in 2006, the research has been focused on natural feed additives which would have a proven positive impact on both production and animal health. Inulin is both the most commonly used and the most effective probiotic additive. The mechanism of inulin interactions with the avian body is complex, multidirectional and not fully understood. Despite a number of unresolved issues, many authors have demonstrated the positive impact of inulin on the host organism. Dietary supplementation of poultry feeding with inulin contributes to the modulation of intestinal microbiota through favouring a quick proliferation of beneficial Bifidobacterium and Lactobacillus strains and inhibiting the growth of pathogenic microbes. There are indications that inulin-provoked changes in the host gut microbiota in poultry may alter the structure and histomorphology of the intestinal mucosa and improve its absorption capacity in poultry. It has also been demonstrated that inulin may affect the immune system and the systemic metabolism of minerals and lipids. The reports on inulin effects on the body and performance of poultry are often contradictory, as the effectiveness of this prebiotic is strongly dependent on the type and dose used, and the duration of its administration.

Is syndromic data from rural poultry farmers a viable poultry disease reporting tool and means of identifying likely farmer responses to poultry disease incursion?

Science.gov (United States)

Mubamba, C; Ramsay, G; Abolnik, C; Dautu, G; Gummow, B

2018-05-01

Syndromic surveillance is a well described tool used in developed countries for alerting authorities to livestock disease incursions. However, little work has been done to evaluate whether this could be a viable tool in countries where disease reporting infrastructure and resources is poor. Consequently, a syndrome-based questionnaire study in Eastern Zambia was designed to gather data on previous encounters farmers had with poultry diseases, as well as control measures they use to mitigate them. Descriptive statistics and logistic regression were used to analyse the data. Farmers reported an overall annual disease incidence in rural poultry for eastern Zambia of 31% (90% CI 29-32%). Occurrence of poultry disease in the last 12 months was associated with use of middlemen to purchase poultry products (p = 0.05, OR = 7.87), poultry products sold or given away from the farm (p = 0.01, OR = 1.92), farmers experiencing a period with more trade of poultry and its products (p = 0.04, OR = 1.70), presence of wild birds near the farm or village (p = 0.00, OR = 2.47) and poultry diseases being reported from neighbouring farms or villages (p = 0.00, OR = 3.12). The study also tentatively identified three poultry diseases (Newcastle Disease, Gumboro Disease and Fowl Pox) from the thirty-four disease syndromes provided by farmers. Farmers reported an incidence of 27% for Newcastle Disease in 2014. When compared with the state veterinary services data which reported Newcastle Disease incidence at 9% in 2014, it seems syndromic data obtained from farmers may be more sensitive in identifying disease incursion. Thirty-six remedies and strategies farmers use to treat and control these diseases were revealed. The main control strategy for identified diseases was vaccination and the main treatment was unspecified herbs, which warrants further investigation and presents an opportunity for further research in ethno-veterinary medicine.

Sharma, Deepak; Espinosa-Solares, Teodoro; Huber, David H

2013-05-01

The purpose of this study was to test whether the performance of a thermophilic CSTR digester that has been stabilized on poultry litter will be enhanced or diminished by the addition of thin stillage as co-substrate. Replicate laboratory digesters, derived from a stable pilot-scale digester, were operated with increasing ratios (w/w) of thin stillage/poultry litter feedstock. After a period of adaptation to 20% and 40% thin stillage, digester performance showed increases in biogas, percent methane and COD removal, as well as a decrease in volatile acids. Peak performance occurred with 60% thin stillage. However, 80% thin stillage caused significant reduction of performance, including declines of methanogenic activity and COD removal. In conclusion, supplementing the thermophilic digestion of poultry litter with thin stillage improved the bioenergy (methane) output, but thin stillage became inhibitory at high concentrations.

Use of poultry manure for amendment of oil-polluted soils in relation to growth of maize (Zea mays L.)

International Nuclear Information System (INIS)

Amadi, A. Ue Bari, Y.

1992-01-01

The use of poultry manure for amelioration of oil-polluted soil was investigated by growing maize (Zea mays L.) under two experimental conditions: increasing the poultry manure rate from 0-20 kg ha -1 at 0.03 L/kg oil treatment level; and increasing the rate of oil treatment from 0-0.2 between the rate of poultry manure added and the enhancement of maize growth. But only a 16-kg ha -1 poultry manure rate and above exerted some beneficial effects on the maize growth relative to the unpolluted, unamended soil. Conversely, increasing oil concentration, regardless of the poultry manure level added, depressed maize growth, but only at oil levels of 0.03 L/kg. A positive correlation was recorded between maize height and leaf area growing in oil-treated soil amended with different poultry manure rates and growing in oil-treated amended with 20 kg ha -1 poultry manure. Amending oil-contaminated soils with poultry manure, should possibly improve soil fertility and maize production

Nutritional Factors Affecting Abdominal Fat Deposition in Poultry: A Review

Science.gov (United States)

Fouad, A. M.; El-Senousey, H. K.

2014-01-01

The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breast yield to meet the demands of consumers, but modern commercial chickens exhibit excessive fat accumulation in the abdomen area. However, dietary composition and feeding strategies may offer practical and efficient solutions for reducing body fat deposition in modern poultry strains. Thus, the regulation of lipid metabolism to reduce the abdominal fat content based on dietary composition and feeding strategy, as well as elucidating their effects on the key enzymes associated with lipid metabolism, could facilitate the production of lean meat and help to understand the fat-lowering effects of diet and different feeding strategies.

Thermophilic Campylobacter spp. are one of the primary causes of bacterial human diarrhea. The consumption of poultry meats, by-products, or both is suspected to be a major cause of human campylobacteriosis. The aims of this study were to determine the prevalence of thermophilic Campylobacter spp. in fresh poultry meat and poultry by-products by conventional culture methods and to confirm Campylobacter jejuni and Campylobacter coli isolates by using the multiplex PCR assay. Two hundred fifty fresh poultry samples were collected from a variety of supermarkets and slaughterhouses located in Sfax, Tunisia, including chicken (n =149) and turkey (n =101). The samples were analyzed using conventional microbiological examinations according to the 2006 International Organization for Standardization method (ISO 10272-1) for Campylobacter spp. Concurrently, a real-time PCR was used for identification of C. jejuni and C. coli . Of the 250 samples of poultry meat and poultry by-products, 25.6% (n = 64) were contaminated with Campylobacter spp. The highest prevalence of Campylobacter spp. was found in chicken meat (26.8%) followed by turkey meat (23.7%). Among the different products, poultry breasts showed the highest contamination (36.6%) followed by poultry by-products (30%), poultry wings (28%) and poultry legs (26%) showed the lowest contamination, and no contamination was found on neck skin. Of the 64 thermophilic Campylobacter isolates, C. jejuni (59.7%) was the most frequently isolated species and 10.9% of the isolates were identified as C. coli . All of the 64 Campylobacter isolates identified by the conventional culture methods were further confirmed by PCR. The seasonal peak of Campylobacter spp. contamination was in the warm seasons (spring and summer). The study concluded that high proportions of poultry meat and poultry by-products marketed in Tunisia are contaminated by Campylobacter spp. Furthermore, to ensure food safety, poultry meats must be properly cooked

Salmonella radicidation of poultry carcasses

International Nuclear Information System (INIS)

Mulder, R.W.A.W.

1982-01-01

This thesis reports investigations using gamma-radiation to decontaminate poultry carcasses. The application to foods of doses of ionizing radiation sufficient to reduce the number of viable specific non-sporeforming pathogenic microorganisms so that none is detectable in the treated food by any standard method is termed radicidation. The doses used in this study were at such a level that no undesirable or unfavourable side-effects occurred. The effects of these doses were studied on salmonellae and other microorganisms present in, or associated with poultry carcasses and in liquid and on solid culture media as well. Decimal reduction (D 10 ) values were estimated. These represent the dose (kGy) required to achieve a reduction in initial colony count from N 0 to 0.1 N 0 . Together with the estimation of the numbers of Salmonella present per carcass the data were used to predict the effect of an ionizing radiation treatment of poultry. Data on the effect of ionizing radiation on the total microflora of poultry carcasses were also collected. (Auth.)

2018-04-01

A study was conducted in Rukomo sector, Nyagatare district, to determine the status of poultry production. A structured questionnaire was used to collect data from 100 poultry farmers randomly as 20 farmers from each of the five cells. Data were analyzed using SPSS version 16 and presented in chart and tables. The majority of the farmers (84%) reared their poultry in free range system while 10% practiced semi-intensive and only 6% did intensive production. Only 12% of the respondents kept exotic poultry breeds. The breeding stock were mostly obtained from local markets (63%) and the average flock size was about 1-10 birds per homestead (70%). The confinement of poultry at night was either in the main domestic house (33%), in kitchen (32%), or in separate poultry house (35%). Flock records were rare and kept by only 9% of respondents. Poultry products were reportedly at high demand by 87% of respondents and 89% farmers reported profit from their enterprises. Lack of veterinary and financial assistance was reported by 72% of respondents. Newcastle disease (57%) was the main health constraint followed by ectoparasites and internal worms. Many farmers (50%) were in dire need of veterinary assistance and financial support to improve their poultry enterprises. Poor management practices were reported to be one of the crucial factors leading to poor production. Lack of quality feeds (38%) and feeding of poultry, credit (20%), and poor market accessibility (19%) were the main challenges reported.

Patterns of poultry exposure in rural and urban areas in China have not been systematically evaluated and compared. The objective of our study is to investigate patterns in human exposure to poultry in rural and urban China. We conducted a two-stage household-based clustered survey on population exposure to live/sick/dead poultry in Xiuning and Shenzhen. Half of the rural households (51%) in Xiuning raised poultry, mostly (78%) free-range. Around half of those households (40%) allowed poultry to stay in their living areas. One quarter of villagers reported having contact with sick or dead poultry. In Shenzhen, 37% urban residents visited live poultry markets. Among these, 40% purchased live poultry and 16% touched the poultry or cages during purchase. Our findings indicated that human exposure to poultry was different in rural and urban areas in China. This discrepancy could contribute to the observed differences in epidemiologic characteristics between urban and rural cases of influenza A(H7N9) and A(H5N1) virus infection. PMID:24769673

Full Text Available Campylobacter spp. are bacterial pathogens associated with human gastroenteritis worldwide. In Europe, campylobacteriosis is one of the leading food-borne bacterial diseases and the consumption of poultry meats is suspected to be one of the major causes of illness. The aim of our research was to determine the number of Campylobacter spp. in poultry carcasses and in poultry meat samples during their storage till to retail markets. The study was conducted from February 2009 to February 2010 at slaughterhouse in Veneto region, followed by a test of fresh poultry meat placed on the market for sale. A total of 90 poultry carcass and 90 samples of poultry meat were examined. The quantitative examination resulted in Campylobacter spp. counts (mean: for carcasses between 2,0 ∙101 ufc/g and 1,5 ∙103 ufc/g (4,2 ∙102 and poultry meat between 2,0 ∙101 ufc/g and 3,7 ∙102 ufc/g (8,1 ∙101. The majority of isolates were classified as Campylobacter jejuni (58,3%, Campylobacter coli (22,9% or Arcobacter cryaerophilus (4,2%.

Poultry food products--a source of avian influenza virus transmission to humans?

Science.gov (United States)

Harder, T C; Buda, S; Hengel, H; Beer, M; Mettenleiter, T C

2016-02-01

Global human mobility and intercontinental connectivity, expansion of livestock production and encroachment of wildlife habitats by invasive agricultural land use contribute to shape the complexity of influenza epidemiology. The OneHealth approach integrates these and further elements into considerations to improve disease control and prevention. Food of animal origin for human consumption is another integral aspect; if produced from infected livestock such items may act as vehicles of spread of animal pathogens, and, in case of zoonotic agents, as a potential human health hazard. Notifiable zoonotic avian influenza viruses (AIV) have become entrenched in poultry populations in several Asian and northern African countries since 2003. Highly pathogenic (HP) AIV (e.g. H5N1) cause extensive poultry mortality and severe economic losses. HPAIV and low pathogenic AIV (e.g. H7N9) with zoonotic propensities pose risks for human health. More than 1500 human cases of AIV infection have been reported, mainly from regions with endemically infected poultry. Intense human exposure to AIV-infected poultry, e.g. during rearing, slaughtering or processing of poultry, is a major risk factor for acquiring AIV infection. In contrast, human infections through consumption of AIV-contaminated food have not been substantiated. Heating poultry products according to kitchen standards (core temperatures ≥70°C, ≥10 s) rapidly inactivates AIV infectivity and renders fully cooked products safe. Nevertheless, concerted efforts must ensure that poultry products potentially contaminated with zoonotic AIV do not reach the food chain. Stringent and sustained OneHealth measures are required to better control and eventually eradicate, HPAIV from endemic regions.

Through a well-to-wheel assessment, several different possible scenarios are assessed, showing...... that under average conditions, the use of poultry fat biodiesel instead of diesel leads to a slight reduction (6%) in greenhouse gas emissions. The analysis shows that poultry fat is already used for different purposes and using poultry fat for biodiesel will therefore remove the poultry fat from its...... original use. This implies that even though the use of biodiesel is assumed to displace petrochemical diesel, the ‘original user’ of the poultry fat will have to find a substitute, whose production leads to a greenhouse gas emissions comparable to what is saved through driving on poultry fat biodiesel...

Planning ahead: Improving escalation plans before the weekend.

Handover is the system by which responsibility for patient care is transferred between healthcare professionals. A significant aspect of handover is the existence of an escalation plan for each patient in case of deterioration over the weekend. According to the Royal College of Physicians, all patients should have a clear escalation plan documented in the notes before a weekend, since parent medical teams (Consultant team in charge of care) are best placed to make these decisions. If left to on-call teams, at a time of deterioration over a weekend, they might not have all available information, the patient might be unable to be involved in the decisions, and the family might not be consulted. With this is mind, we decided to analyse the existing handover process in a medium sized district general hospital, with the aim of improving the process and the documentation of escalation plans. The results from our retrospective analysis of the system in place revealed a significant lack of documentation of escalation plans in the medical notes. Three sample wards were selected to analyse the current handover system and test proposed measures before hospital-wide implementation. After trialling of a physical handover meeting in addition to the existing intranet system and a proforma for the Friday ward round, the documentation of escalation plans in the patients' notes improved from 9.1% to 41.1%. Based on these results, as well as formal feedback from junior doctors and informal feedback from other staff, the physical handover meeting and Friday ward round proforma will be implemented throughout the Trust. Our interventions led to an improvement in the documentation of escalation plans in our hospital, thus saving precious time in the event of a patient's deterioration. This also ensures that families and patients are involved in the decision making process and kept informed, and reduces the burden for the weekend on-call teams.

Because food and poultry industries are demanding an improvement in written communication skills among graduates, research paper writing should be an integral part of a senior undergraduate class. However, scientific writing assignments are often treated as secondary to developing the technical skills of the students. Scientific research paper writing has been emphasized in an undergraduate course on advanced food microbiology taught in the Poultry Science Department at Texas A& M University (College Station, TX). Students' opinions suggest that research paper writing as part of a senior course in Poultry Science provides students with scientific communication skills and useful training for their career, but more emphasis on reading and understanding scientific literature may be required.

Ionizing energy treatment of poultry

International Nuclear Information System (INIS)

Mulder, R.W.A.W.

1983-01-01

The application of an ionizing energy treatment to poultry carcasses results in a decrease of the number of potentially pathogenic microorganisms, e.g. Salmonellae. At the same time the refrigerated shelf life of treated poultry products is considerably increased. To achieve these beneficial effects doses ranging from 2.00 to 9.00 kGy are needed, but in poultry doses over 5.00 kGy may cause undesirable side-effects. To asses the microbiological quality of ionizing radiation treated end-products adequate isolation methods should be used to include all sublethally injured microorganisms in the colony counts. The assessment of the required lethality of an ionizing energy treatment is difficult as D 10 (decimal reduction) - values depend greatly on several parameters

Cassava: Nutrient composition and nutritive value in poultry diets

Directory of Open Access Journals (Sweden)

Natalie K. Morgan

2016-12-01

Full Text Available Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is, however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid (HCN. With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets.

Improving IMRT-plan quality with MLC leaf position refinement post plan optimization

International Nuclear Information System (INIS)

Niu Ying; Zhang Guowei; Berman, Barry L.; Parke, William C.; Yi Byongyong; Yu, Cedric X.

2012-01-01

Purpose: In intensity-modulated radiation therapy (IMRT) planning, reducing the pencil-beam size may lead to a significant improvement in dose conformity, but also increase the time needed for the dose calculation and plan optimization. The authors develop and evaluate a postoptimization refinement (POpR) method, which makes fine adjustments to the multileaf collimator (MLC) leaf positions after plan optimization, enhancing the spatial precision and improving the plan quality without a significant impact on the computational burden. Methods: The authors’ POpR method is implemented using a commercial treatment planning system based on direct aperture optimization. After an IMRT plan is optimized using pencil beams with regular pencil-beam step size, a greedy search is conducted by looping through all of the involved MLC leaves to see if moving the MLC leaf in or out by half of a pencil-beam step size will improve the objective function value. The half-sized pencil beams, which are used for updating dose distribution in the greedy search, are derived from the existing full-sized pencil beams without need for further pencil-beam dose calculations. A benchmark phantom case and a head-and-neck (HN) case are studied for testing the authors’ POpR method. Results: Using a benchmark phantom and a HN case, the authors have verified that their POpR method can be an efficient technique in the IMRT planning process. Effectiveness of POpR is confirmed by noting significant improvements in objective function values. Dosimetric benefits of POpR are comparable to those of using a finer pencil-beam size from the optimization start, but with far less computation and time. Conclusions: The POpR is a feasible and practical method to significantly improve IMRT-plan quality without compromising the planning efficiency.

Poultry studies and anthropological research strategies

International Nuclear Information System (INIS)

Whyte, M.

2002-01-01

Poultry are not simply birds; they are also a human creation, a social and cultural practice. The human element is the justification for an anthropology of poultry. Such an anthropology combines the objective research strategies familiar to the natural sciences with what is often called 'subjective' or qualitative research. In the study of poultry management, it is important that both research strategies focus on differences and variation. The subjective approach is particularly useful in identifying and understanding how the motivations and strategies of local actors are dependent on the social positions, which they occupy in their specific societies.

Combustion Of Poultry-Derived Fuel in a CFBC

Science.gov (United States)

Jia, Lufei; Anthony, Edward J.

Poultry farming generates large quantities of waste. Current disposal practice is to spread the poultry wastes onto farmland as fertilizer. However, as the factory farms for poultry grow both in numbers and size, the amount of poultry wastes generated has increased significandy in recent years. In consequence, excessive application of poultry wastes on farmland is resulting in more and more contaminants entering the surface water. One of the options being considered is the use of poultry waste as power plant fuel. Since poultry-derived fuel (PDF) is biomass, its co-firing will have the added advantage of reducing greenhouse gas emissions from power generation. To evaluate the combustion characteristics of co-firing PDF with coal, combustion tests of mixtures of coal and PDF were conducted in CanmetENERGY's pilot-scale CFBC. The goal of the tests was to verify that PDF can be co-fired with coal and, more importantly, that emissions from the combustion process are not adversely affected by the presence of PDF in the fuel feed. The test results were very promising and support the view that co-firing in an existing coal-fired CFBC is an effective method of utilizing this potential fuel, both resolving a potential waste disposal problem and reducing the amount of CO2 released by the boiler.

Jardim, Kevin P.

Supplier performance that meets the requirements of the customer has long plagued quality professionals. Despite the vast efforts by organizations to improve supplier performance, little has been done to standardize the plan to improve performance. This project presents a guideline and problem-solving strategy using a Define, Measure, Analyze, Improve, and Control (DMAIC) structured tool that will assist in the management and improvement of supplier performance. An analysis of benchmarked Quality Improvement Plans indicated that this topic needs more focus on how to accomplish improved supplier performance. This project is part of a growing body of supplier continuous improvement efforts. With the input of Zodiac Aerospace quality professionals this project's results provide a solution to Quality Improvement Plans and show objective evidence of its benefits. This project contributes to the future research on similar topics.

Baron, Patrick; Frattaroli, Shannon

2016-01-01

The objective of this study was to document and understand the perceptions and opinions of small-scale poultry producers who market directly to consumers about microbial food safety risks in the poultry supply chain. Between January and November 2014, we conducted semi-structured, in-depth interviews with a convenience sample of 16 owner-operators of Maryland direct-market commercial poultry farms. Three overarching thematic categories emerged from these interviews that describe: 1) characteristics of Maryland direct-market poultry production and processing; 2) microbial food safety risk awareness and risk management in small-scale poultry production, slaughter and processing; and 3) motivations for prioritizing food safety in the statewide direct-market poultry supply chain. Key informants provided valuable insights on many topics relevant to evaluating microbial food safety in the Maryland direct-market poultry supply chain, including: direct-market poultry production and processing practices and models, perspectives on issues related to food safety risk management, perspectives on direct-market agriculture economics and marketing strategies, and ideas for how to enhance food safety at the direct-market level of the Maryland poultry supply chain. The findings have policy implications and provide insights into food safety in small-scale commercial poultry production, processing, distribution and retail. In addition, the findings will inform future food safety research on the small-scale US poultry supply chain.

Malodour from the poultry farms could cause air pollution and therefore potentially dangerous to humans' and animals' health. This issue also poses sustainability risk to the poultry industries due to objections from local community. The aim of this paper is to develop and calibrate a cost effective and efficient electronic nose for poultry farm air monitoring. The instrument main components include sensor chamber, array of specific sensors, microcontroller, signal conditioning circuits and wireless sensor networks. The instrument was calibrated to allow classification of different concentrations of main volatile compounds in the poultry farm malodour. The outcome of the process will also confirm the device's reliability prior to being used for poultry farm malodour assessment. The Multivariate Analysis (HCA and KNN) and Artificial Neural Network (ANN) pattern recognition technique was used to process the acquired data. The results show that the instrument is able to calibrate the samples using ANN classification model with high accuracy. The finding verifies the instrument's performance to be used as an effective poultry farm malodour monitoring.

Trends in microbial control techniques for poultry products.

Silva, Filomena; Domingues, Fernanda C; Nerín, Cristina

2018-03-04

Fresh poultry meat and poultry products are highly perishable foods and high potential sources of human infection due to the presence of several foodborne pathogens. Focusing on the microbial control of poultry products, the food industry generally implements numerous preventive measures based on the Hazard Analysis and Critical Control Points (HACCP) food safety management system certification together with technological steps, such as refrigeration coupled to modified atmosphere packaging that are able to control identified potential microbial hazards during food processing. However, in recent years, to meet the demand of consumers for minimally processed, high-quality, and additive-free foods, technologies are emerging associated with nonthermal microbial inactivation, such as high hydrostatic pressure, irradiation, and natural alternatives, such as biopreservation or the incorporation of natural preservatives in packaging materials. These technologies are discussed throughout this article, emphasizing their pros and cons regarding the control of poultry microbiota and their effects on poultry sensory properties. The discussion for each of the preservation techniques mentioned will be provided with as much detail as the data and studies provided in the literature for poultry meat and products allow. These new approaches, on their own, have proved to be effective against a wide range of microorganisms in poultry meat. However, since some of these emergent technologies still do not have full consumer's acceptability and, taking into consideration the hurdle technology concept for poultry processing, it is suggested that they will be used as combined treatments or, more frequently, in combination with modified atmosphere packaging.

Mycotoxins and their impact on poultry production

Directory of Open Access Journals (Sweden)

Ivković Goran R.Ž.

2005-01-01

Full Text Available Only two years after the great expansion of "AGROŽIV" company, it was evident that mycotoxins have great impact on all segments of poultry production. During that year we were for the first time faced up with problems in poultry fattening. It was not possible to explain the present problems only by bacterial and viral infections, so we assumed that there is another reason for the observed clinical picture. From that time we started to pay more attention on contamination of poultry feed with mycotoxins. In the four years' period, from 1988 to 2002, 57 samples were analyzed for the presence of mycotoxins. Mycotoxicological investigations revealed the presence of T-2 toxin in 19 samples at concentrations less than 0.3 mg/kg, in 18 samples at concentration of 0.5 mg/kg, and in 3 samples 1.0 mg/kg. Beside this, type A trichotecene DAS was found in 6 of tested samples, and ochratoxin A and in 1 sample. Clinical picture and damages varied depending on mycotoxins' concentrations and poultry age. To exceede this problem in animal production we tried to use the organic and anorganic mycotoxin adsorbents as additives of poultry feed, but the results were not satisfactory enough. So, we resumed that if we really want to resolve problem of mycotoxins we have to start from the field production of poultry feed components.

A simulated supermarket setting (SSS) test was conducted to determine whether consumers (n = 126) would purchase irradiated poultry products, and the effects of marketing strategies on consumer purchase of irradiated poultry products. Consumer preference for irradiated poultry was likewise determined using a home-use test. A slide program was the most effective educational strategy in changing consumers' purchase behavior. The number of participants who purchased irradiated boneless, skinless breasts and irradiated thighs after the educational program increased significantly from 59.5 and 61.9% to 83.3 and 85.7% for the breasts and thighs, respectively. Using a label or poster did not increase the number of participants who bought irradiated poultry products. About 84% of the participants consider it either 'somewhat necessary' or 'very necessary' to irradiate raw chicken and would like all chicken that was served in restaurants or fast food places to be irradiated. Fifty-eight percent of the participants would always buy irradiated chicken if available, and an additional 27% would buy it sometimes. About 44% of the participants were willing to pay the same price for irradiated chicken as for nonirradiated. About 42% of participants were willing to pay 5% or more than what they were currently paying for nonirradiated chicken. Seventy-three percent or more of consumers who participated in the home-use test (n = 74) gave the color, appearance, and aroma of the raw poultry products a minimum rating of 7 (= like moderately). After consumers participated in a home-use test, 84 and 88% selected irradiated thighs and breasts, respectively, over nonirradiated in a second SSS test

2008-01-01

The applicability of Fenton's oxidation as an advanced treatment for chemical oxygen demand (COD) and color removal from anaerobically treated poultry manure wastewater was investigated. The raw poultry manure wastewater, having a pH of 7.30 (±0.2) and a total COD of 12,100 (±910) mg/L was first treated in a 15.7 L of pilot-scale up-flow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated for 72 days at mesophilic conditions (32 ± 2 deg. C) in a temperature-controlled environment with three different hydraulic retention times (HRT) of 15.7, 12 and 8.0 days, and with organic loading rates (OLR) between 0.650 and 1.783 kg COD/(m 3 day). Under 8.0 days of HRT, the UASB process showed a remarkable performance on total COD removal with a treatment efficiency of 90.7% at the day of 63. The anaerobically treated poultry manure wastewater was further treated by Fenton's oxidation process using Fe 2+ and H 2 O 2 solutions. Batch tests were conducted on the UASB effluent samples to determine the optimum operating conditions including initial pH, effects of H 2 O 2 and Fe 2+ dosages, and the ratio of H 2 O 2 /Fe 2+ . Preliminary tests conducted with the dosages of 100 mg Fe 2+ /L and 200 mg H 2 O 2 /L showed that optimal initial pH was 3.0 for both COD and color removal from the UASB effluent. On the basis of preliminary test results, effects of increasing dosages of Fe 2+ and H 2 O 2 were investigated. Under the condition of 400 mg Fe 2+ /L and 200 mg H 2 O 2 /L, removal efficiencies of residual COD and color were 88.7% and 80.9%, respectively. Under the subsequent condition of 100 mg Fe 2+ /L and 1200 mg H 2 O 2 /L, 95% of residual COD and 95.7% of residual color were removed from the UASB effluent. Results of this experimental study obviously indicated that nearly 99.3% of COD of raw poultry manure wastewater could be effectively removed by a UASB process followed by Fenton's oxidation technology used as a post-treatment unit

On the basis of preliminary test results, effects of increasing dosages of Fe2+ and H2O2 were investigated. Under the condition of 400 mg Fe2+/L and 200 mg H2O2/L, removal efficiencies of residual COD and color were 88.7% and 80.9%, respectively. Under the subsequent condition of 100 mg Fe2+/L and 1200 mg H2O2/L, 95% of residual COD and 95.7% of residual color were removed from the UASB effluent. Results of this experimental study obviously indicated that nearly 99.3% of COD of raw poultry manure wastewater could be effectively removed by a UASB process followed by Fenton's oxidation technology used as a post-treatment unit.

Only two years after the great expansion of "AGROŽIV" company, it was evident that mycotoxins have great impact on all segments of poultry production. During that year we were for the first time faced up with problems in poultry fattening. It was not possible to explain the present problems only by bacterial and viral infections, so we assumed that there is another reason for the observed clinical picture. From that time we started to pay more attention on contamination of poultry feed with m...

Economic epidemiology of avian influenza on smallholder poultry farms☆

Science.gov (United States)

Boni, Maciej F.; Galvani, Alison P.; Wickelgren, Abraham L.; Malani, Anup

2013-01-01

Highly pathogenic avian influenza (HPAI) is often controlled through culling of poultry. Compensating farmers for culled chickens or ducks facilitates effective culling and control of HPAI. However, ensuing price shifts can create incentives that alter the disease dynamics of HPAI. Farmers control certain aspects of the dynamics by setting a farm size, implementing infection control measures, and determining the age at which poultry are sent to market. Their decisions can be influenced by the market price of poultry which can, in turn, be set by policy makers during an HPAI outbreak. Here, we integrate these economic considerations into an epidemiological model in which epidemiological parameters are determined by an outside agent (the farmer) to maximize profit from poultry sales. Our model exhibits a diversity of behaviors which are sensitive to (i) the ability to identify infected poultry, (ii) the average price of infected poultry, (iii) the basic reproductive number of avian influenza, (iv) the effect of culling on the market price of poultry, (v) the effect of market price on farm size, and (vi) the effect of poultry density on disease transmission. We find that under certain market and epidemiological conditions, culling can increase farm size and the total number of HPAI infections. Our model helps to inform the optimization of public health outcomes that best weigh the balance between public health risk and beneficial economic outcomes for farmers. PMID:24161559

Health and Welfare in Organic Poultry Production

Directory of Open Access Journals (Sweden)

Berg C

2002-03-01

Full Text Available This review paper deals with the major health and welfare aspects of organic poultry production. The differences between organic and conventional egg and poultry meat production are discussed, with the main emphasis on housing and management requirements, feed composition and the use of veterinary prophylactic and therapeutic drugs. The effects of the legislation and statutes for organic farming on the health and welfare of the birds are also discussed, especially in relation to the biosecurity problems associated with free-range systems, the occurrence of behavioural disturbances in loose housed flocks and the use of veterinary drugs and vaccinations in general. The results from a questionnaire sent out to all Swedish organic egg producers, where questions about the farmer's perception of the birds' health status were included, are presented at the end of the paper. It is concluded that most of the health and welfare problems seen in conventional poultry systems for loose housed or free ranging birds can also been found on organic poultry farms. It is also concluded that there is a need for information about biosecurity, disease detection and disease prevention on organic poultry farms.

Live-animal markets are a culturally important feature of meat distribution chains in many populations, yet they provide an opportunity for the maintenance and transmission of potentially emergent zoonotic pathogens. The ongoing human outbreak of avian H7N9 in China highlights the need for increased surveillance and control in these live-bird markets (LBMs). Closure of retail markets in affected areas rapidly decreased human cases to rare, sporadic occurrence, but little attention has been paid thus far to the role of upstream elements of the poultry distribution chain such as wholesale markets. This could partly explain why transmission in poultry populations has not been eliminated more broadly. We present surveillance data from both wholesale live-bird markets (wLBMs) and rLBMs in Shantou, China (from 2004-2006), and call on disease-dynamic theory to illustrate why closing rLBMs has only minor effects on the overall volume of transmission. We show that the length of time birds stay in rLBMs can severely limit transmission there, but that the system-wide effect may be reduced substantially by high levels of transmission upstream of retail markets. Management plans that minimize transmission throughout the entire poultry supply chain are essential for minimizing exposure to the public. These include reducing stay-time of birds in markets to 1 day, standardizing poultry supply chains to limit transmission in pre-retail settings, and monitoring strains with epidemiological traits that pose a high risk of emergence. These actions will further limit human exposure to extant viruses and reduce the likelihood of the emergence of novel strains by decreasing the overall volume of transmission.

This study examines whether there is active planning for health improvement in the English spatial planning system and how this varies across two regions using a combination of telephone surveys and focus group interviews in 2005 and 2010. The spatial planning profession was found to be ill-equipped to consider the health and well-being implications of its actions, whilst health professionals are rarely engaged and have limited understanding and aspirations when it comes to influencing spatial planning. Strategic Environmental Assessment was not considered to be successful in integrating health into spatial plans, given it was the responsibility of planners lacking the capacity to do so. For their part, health professionals have insufficient knowledge and understanding of planning and how to engage with it to be able to plan for health gains rather than simply respond to health impacts. HIA practice is patchy and generally undertaken by health professionals outside the statutory planning framework. Thus, whilst appropriate assessment tools exist, they currently lack a coherent context within which they can function effectively and the implementation of the Kiev protocol requiring the engagement of health professionals in SEA is not to likely improve the consideration of health in planning while there continues to be separation of functions between professions and lack of understanding of the other profession. -- Highlights: ► Health professionals have limited aspirations for health improvement through the planning system. ► Spatial planners are ill-equipped to understand the health and well-being implications of their activities. ► SEA and HIA currently do not embed health consideration in planning decisions. ► The separation of health and planning functions is problematic for the effective conduct of SEA and/or HIA

Control of poultry coccidiosis: changing trends.

Science.gov (United States)

Tewari, A K; Maharana, B R

2011-06-01

Coccidiosis is the most important protozoan disease affecting the poultry industry worldwide. Control of poultry coccidiosis is presently based on managerial skills and the use of prophylactic coccidiostatic drugs. With the emergence of drug resistant Eimeria strains, emphasis has been laid on development and use of safer vaccines; some of them have been commercialized successfully. The present review deals with the various factors responsible for the development of clinical coccidiosis in poultry as well as an overview of the currently available inducers and boosters of immunity against coccidiosis. There are three groups of vaccines currently available against coccidiosis which can be distinguished on the basis of characteristics of the Eimeria species included in the respective products, viz. vaccines based on live virulent strains, vaccines based on live attenuated strains, and vaccines based on live strains that are relatively tolerant to the ionophore compounds. The latter vaccine combines the early chemotherapeutic effect of ionophores with the late prophylactic effect of vaccination. Although in the near future more varieties of oocyst based live vaccines are expected, identification of selective coccidian-specific immunoprotective molecules is likely to get more attention to facilitate the sustainable control of poultry coccidiosis.

Nutrition in Relation to Diseases and Heat stress in Poultry

Full Text Available Different diseases conditions and stress factors are responsible for high morbidity and mortality of present day poultry. Nutritional strategy and proper feed formulation with specific dietary regimen can combat this up to a certain extent. The incidence of various infectious diseases, nervous disorders and metabolic disorders can be minimized through proper feed regimen. There is a stiff competition and restrictions in the global market of poultry products which can be addressed with proper management of emerging and important diseases with economic productions and quality poultry products free of elements detrimental to human health. Researchers have made efforts to prevent such damage to poultry and poultry product through dietary manipulations. Heat stress can lead to a reduction in the defense mechanisms of birds or to a relative state of immunosuppression. The health status of the poultry is facing new challenges today which can be suitably addressed by the right scientific and advanced nutritional manoeuvres and make the poultry farming more profitable and presentable in the global market.

Recent advances in role of chromium and its antioxidant combinations in poultry nutrition: A review

Directory of Open Access Journals (Sweden)

Z. Haq

2016-12-01

Full Text Available Poultry is reared in open side houses in most of the tropical countries, which results in huge temperature variation in shed causing stress resulting in increased demand of antioxidant supplementation. Since cooling of poultry houses or environment control is very expensive, thus methods focused on nutritional modifications appears to be the much logical approach. Stress increases mineral and vitamin mobilization from tissues and their excretion. Effect of some minerals and vitamin supplements such as chromium (Cr and ascorbic acid to elevate the negative effects of environmental stress is well documented. Cr functions as an antioxidant and its deficiency are said to disrupt carbohydrate and protein metabolism. Cr has been utilized for weight gain, to improve feed conversion ratio, increase relative organ weight, muscle development, decrease cholesterol, increase high-density lipoprotein cholesterol, and improve nutrient digestion. Therefore, the present review discusses the beneficial aspects of Cr with its effect in different doses and antioxidant combinations to explore and promote its optimum utilization in poultry nutrition and production.

Saleh, H.M.; Elwan, K.M.; El-Fouly, H.A.; Ibrahim, I.I.; Salama, A.M.; Elashry, M.A.

2002-01-01

The use of poultry waste as a dietary supplement in ruminant ration could have a considerable effect on reducing costs, insufficiency of protein in diet, and on solving disposal problems. The chemical composition of poultry waste and its safe use in ruminant nutrition were investigated prior to its use as a dietary supplement. No appreciable differences in chemical composition were noted in poultry wastes between oven and sun dried forms. The high content of protein, energy, and minerals in poultry waste indicated its importance as a partial substitute for concentrates in the diet. The numbers of total bacteria and pathogenic microorganisms such as Salmonella and E. coli detected in poultry waste were within the acceptable limits. Farm testing of rations containing poultry wastes were carried out on sheep (ewes and lambs), Friesian cattle and buffalo heifers. In ewes fed during late pregnancy and lactation, milk yield and performance did not show any significant changes. Lambs suckled from ewes fed on poultry waste did not show any significant difference in weaning weight, average daily weight gain or feed efficiency (kg feed used/kg weaned weight). However, the poultry waste group had shorter age at weaning than the control group. In another feeding trial on growing lambs after weaning, mean daily body weight gain was higher in lambs fed on a ration containing poultry waste than the control ration. In Friesian and buffalo calves, no significant differences in average daily body weight gain were found as a result of inclusion of poultry waste in the ration. In buffalo heifers various estimated reproductive parameters indicated no appreciable differences due to the inclusion of poultry waste in the diet except that the number of ovulations and number of services/conception were both higher in the group fed with poultry waste.

2017-12-01

Full Text Available Cattle and poultry enterprises are among the major contributors to food security and socioeconomic empowerment of households in Uganda. However, various diseases constrain their productivity. A two-year retrospective study between April 2012 and March 2014 was conducted using records for cattle and poultry diseases diagnosed at the Central Diagnostic Laboratory (CDL to determine prevalent diseases in Uganda. The laboratory received 836 samples from poultry (36.3% and cattle (63.7%. Of the 836 samples, 47.5% had a definitive diagnosis of disease causation. Most of the cattle and poultry diseases diagnosed were protozoan diseases (39.3% followed by bacterial (21.4%, viral (17.1%, helminthiasis (11.1%, nutritional diseases (4% and others (7.1%. For poultry, viral diseases (29.5% and protozoan diseases (27.1% especially newcastle disease (44.3% and coccidiosis (100% respectively, were the most diagnosed. While for cattle, hemo-protozoan parasites (52.1% were the most prevalent, of which 92.9% were east coast fever infection. Bacterial infection (20.5% in cattle were the second most diagnosed diseases and mastitis was the most diagnosed (46.2%. In summary, coccidioisis, collibacillosis, newcastle disease, gumboro disease, and avian helminthiasis were the most prevalent poultry diseases while in cattle, east coast fever, helminthiasis, mastitis, brucellosis and rabies were the most frequently diagnosed diseases. This study has identified the major diseases that hinder poultry and cattle production in Uganda. The data generated by CDL could be used for surveillance, monitoring and designing strategic interventions for control of poultry and cattle diseases in Uganda.

Microbial mineralization of organic nitrogen forms in poultry litters.

Ammonia volatilization from the mineralization of uric acid and urea has a major impact on the poultry industry and the environment. Dry acids are commonly used to reduce ammonia emissions from poultry houses; however, little is known about how acidification affects the litter biologically. The goal of this laboratory incubation was to compare the microbiological and physiochemical effects of dry acid amendments (Al+Clear, Poultry Litter Treatment, Poultry Guard) on poultry litter to an untreated control litter and to specifically correlate uric acid and urea contents of these litters to the microbes responsible for their mineralization. Although all three acidifiers eventually produced similar effects within the litter, there was at least a 2-wk delay in the microbiological responses using Poultry Litter Treatment. Acidification of the poultry litter resulted in >3 log increases in total fungal concentrations, with both uricolytic (uric acid degrading) and ureolytic (urea degrading) fungi increasing by >2 logs within the first 2 to 4 wk of the incubation. Conversely, total, uricolytic, and ureolytic bacterial populations all significantly declined during this same time period. While uric acid and urea mineralization occurred within the first 2 wk in the untreated control litter, acidification resulted in delayed mineralization events for both uric acid and urea (2 and 4 wk delay, respectively) once fungal cell concentrations exceeded a threshold level. Therefore, fungi, and especially uricolytic fungi, appear to have a vital role in the mineralization of organic N in low-pH, high-N environments, and the activity of these fungi should be considered in best management practices to reduce ammonia volatilization from acidified poultry litter.

[Epizootiology of aegyptianellosis in poultry].

Science.gov (United States)

Tsanov, Ts S

1983-01-01

Epizootiologic studies were carried out on avian aegyptianellosis, especially with birds raised at poultry dressing combines and industrial poultry farms within the country. It was found that the mechanism of infection transmission was mediated not only by the role of Argas persicus ticks but also by bed bug insects of the Cimex genus, belonging to the Hemiptera order. Carriers of aegyptianellosis might also be migratory birds coming from tropical countries, such as swallows. It is concluded that avian aegyptianellosis can be referred to the group of the natural focal transmissive infections.

PRODUCTION AND SUPPLY BALANCE OF POULTRY MEAT IN CROATIA

Directory of Open Access Journals (Sweden)

Ivo Grgić

2015-06-01

Full Text Available Poultry meat is an important protein source in the human consumption. The main factors that have a positive effect on the development of the poultry industry are short production cycle, relatively low cost and the lack of religious restrictions on consumption. Chicken meat has the biggest share in the structure of poultry meat. The paper objective was to calculate the level of self-sufficiency degree in poultry meat in Croatia in the period from 2000 to 2012 and the degree of self-sufficiency in 2016 based on the results obtained. The method of balancing was used for calculation of self-sufficiency degree. The degree of self-sufficiency in the production of poultry meat in Croatia is higher than in other types of meat being between 80 and 90%. However, further decrease is expected and in 2016 domestic production would meet 81.17% of the domestic needs.

Qiu, Guannan; Guo, Mingxin

2010-01-01

Utilization of poultry litter as a source material for generating activated carbon is a value-added and environmentally beneficial approach to recycling organic waste. In this study, the overall quality of poultry litter-derived granular activated carbon was systematically evaluated based on its various physical and chemical properties. Granular activated carbon generated from pelletized poultry litter following a typical steam-activation procedure possessed numerous micropores in the matrix. The product exhibited a mean particle diameter of 2.59 mm, an apparent density of 0.45 g cm(-3), a ball-pan hardness of 91.0, an iodine number of 454 mg g(-1), and a BET surface area of 403 m(2) g(-1). It contained high ash, nitrogen, phosphorus contents and the trace elements Cu, Zn, and As. Most of the nutrients and toxic elements were solidified and solution-unextractable. In general, poultry litter-based activated carbon demonstrated overall quality comparable to that of low-grade commercial activated carbon derived from coconut shell and bituminous coal. It is promising to use poultry litter as a feedstock to manufacture activated carbon for wastewater treatment.

2012-06-01

Full Text Available Primary role of food is to provide nutritive stuffs in sufficient amounts to meet nutritive requirements. However, recent scientific findings confirm assumptions that particular food or its ingredients had positive physiological and psychological effects on health. Functional food is referred to food rich in ingredients, having beneficial effects on one or more functions in an organism. By consuming functional food consumers can expect some health benefits. Production of poultry products as functional food is getting more important on foreign markets while portion of such products on domestic food market is insignificant. The aim of this paper is to present possibilities for enrichment of poultry products, such as broiler and turkey meat and chicken eggs, as they can be characterized as functional food. Functional ingredients in poultry products are polyunsaturated fatty acids (LNA, EPA and DHA and antioxidants. Enrichment of poultry products with the stated ingredients that are beneficial for human health is subject of many researches, and only recently have researches been directed towards assessment of market sustainability of such products.

Illango, J.; Etoori, A.; Olupot, H.; Mabonga, J.

2002-01-01

A baseline study on rural poultry production, management and health was conducted in six selected villages in an agro-pastoral and montane zone of Uganda during the wet and dry season. In the 114 rural households visited, the farmers were interviewed by using a questionnaire. Poultry flocks were examined and samples were collected for laboratory investigations. A free-range management system with mixed poultry species was practiced by farmers in both zones. The major poultry flock parameters in the agro-pastoral and montane zone were, respectively, mean flock size of 22 (with a range of 3-65) and 17.5 (with a range of 6-60); mean hen:cock ratio of 2.6 to 1 and 4.8 to 1; mean egg production per hen per year of 8.8 and 11.5; mean hatchability of 70.8% and 85.7%; mean chick mortality of 39.6% and 28.6%. The flock ownership was single, mixed or shared among family households. Women were more involved in most of the activities regarding poultry management, although in both zones a division of labour existed within the household. Men predominantly made the decisions on sale, consumption and treatment of poultry. The most important health problems in the flocks in both zones in the two seasons were coughing, diarrhoea, fowl pox and internal parasites. It was concluded that the major constraints affecting rural poultry production in the two zones were diseases especially Newcastle disease and parasites, inadequate housing and poor feed supplementation especially in the dry season. Women had important responsibilities in rural poultry production in the two zones. The findings form the basis for an assessment of the effects of interventions on rural poultry production in the two zones. (author)

2002-05-22

The purpose of this project was to assess poultry grower residue, or litter (manure plus absorbent biomass), as a fuel source for Community Power Corporation's small modular biopower system (SMB). A second objective was to assess the poultry industry to identify potential ''on-site'' applications of the SMB system using poultry litter residue as a fuel source, and to adapt CPC's existing SMB to generate electricity and heat from the poultry litter biomass fuel. Bench-scale testing and pilot testing were used to gain design information for the SMB retrofit. System design approach for the Phase II application of the SMB was the goal of Phase I testing. Cost estimates for an onsite poultry litter SMB were prepared. Finally, a market estimate was prepared for implementation of the on-farm SMB using poultry litter.

MANAGEMENT PLANS AND THEIR IMPACT ON SCHOOL IMPROVEMENT

2016-06-01

Full Text Available OECD (2015 states that management's leadership is a critical factor for implementing reforms and improving schools. Candidates are required to submit a management plan outlining the framework of a plan to be followed during their 4 year term. Despite the plan outlined in the proposal, the implicit "non aggression pact" between the participants (the teachers and the directors, who are teachers themselves, makes change difficult. As a result, management plans have little impact on improving methods of teaching and academic results achieved by the students. In this article we have tried to achieve three objectives: 1 analyze the relationship between the renewal, selection and appointment of a director with the management plan around our country, 2 analyze which aspects are those that, according to major international studies, should determine the content, development and evaluation of a management plan, and 3 to suggest how one could implement a management plan for an education center or school.

Kearney, Gregory D; Gallagher, Barbara; Shaw, Robert

2016-01-01

The aim of this pilot study was to evaluate respiratory behavior and respiratory indices of poultry workers on family-owned, poultry farms with 10 or less employees in North Carolina. A field study was conducted to collect data on participants (N = 24) using spirometry, fractional exhaled nitric oxide (Feno), and an interviewer-administered questionnaire. The majority of workers (76%) ranked respiratory protection as being important, yet 48% reported never or rarely wearing respiratory protection when working in dusty conditions. A large percent of workers reported eye (55%) and nasal (50%) irritation and dry cough (50%). On average, pulmonary lung function and Feno tests were normal among nonsmokers. In bivariate analysis, significant associations were identified between working 7 days on the farm (P = .01), with eye irritation, and working 5 or fewer years in poultry farming (P = .01). Poultry workers on family-owned farms spend a considerable amount of work time in poultry houses and report acute respiratory-related health symptoms. Administrative controls among small, family-owned poultry farms are necessary to improve and promote safety and health to its employees.

A retrospective study and predictive modelling of Newcastle Disease trends among rural poultry of eastern Zambia.

Mubamba, C; Ramsay, G; Abolnik, C; Dautu, G; Gummow, B

2016-10-01

Newcastle Disease (ND) is a highly infectious disease of poultry that seriously impacts on food security and livelihoods of livestock farmers and communities in tropical regions of the world. ND is a constant problem in the eastern province of Zambia which has more than 740 000 rural poultry. Very few studies give a situational analysis of the disease that can be used for disease control planning in the region. With this background in mind, a retrospective epidemiological study was conducted using Newcastle Disease data submitted to the eastern province headquarters for the period from 1989 to 2014. The study found that Newcastle Disease cases in eastern Zambia followed a seasonal and cyclic pattern with peaks in the hot dry season (Overall Seasonal Index 1.1) as well as cycles every three years with an estimated provincial incidence range of 0.16 to 1.7% per year. Annual trends were compared with major intervention policies implemented by the Zambian government, which often received donor support from the international community during the study period. Aid delivered through government programmes appeared to have no major impact on ND trends between 1989 and 2014 and reasons for this are discussed. There were apparent spatial shifts in districts with outbreaks over time which could be as a result of veterinary interventions chasing outbreaks rather than implementing uniform control. Data was also fitted to a predictive time series model for ND which could be used to plan for future ND control. Time series modelling showed an increasing trend in ND annual incidence over 25 years if existing interventions continue. A different approach to controlling the disease is needed if this trend is to be halted. Conversely, the positive trend may be a function of improved reporting by farmers as a result of more awareness of the disease. Copyright © 2016 Elsevier B.V. All rights reserved.

Characteristics and parameters of family poultry production in Africa. Results of a FAO/IAEA co-ordinated research programme

International Nuclear Information System (INIS)

2002-01-01

One of the tasks of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is to promote the use of nuclear techniques for improving disease diagnosis and monitoring disease control programmes in order to optimise animal production in developing countries. An applied research programme was initiated in 1998 with funding from the Regular Budget to promote farmyard poultry production in Africa by developing practical vaccination strategies against Newcastle disease and Gumboro disease in various countries in Africa and monitoring immunity using an ELISA technique. Following initial discussions with experts from various universities and FAO it became clear that in order to improve farmyard poultry production effectively it was essential to initiate a holistic approach. Consequently, it was decided to first collect production data of the existing situation in a standardised fashion, subsequently analyse the production constraints and finally initiate interventions not only by vaccinating poultry but also by introducing improvements in housing, feeding and commercialisation. At the same time a practical and robust ELISA test for detecting antibodies against Newcastle disease was developed at the FAO/IAEA Agriculture and Biotechnology Laboratory in Seibersdorf, Austria. The results of the standardised survey to collect production data of the current situation are reported in the present publication together with an analysis of production constraints, a number of review articles on family poultry production in Africa and a comparative analysis of the results from the various countries

Poultry litter power station in the United Kingdom

1995-01-01

Poultry litter has presented a waste disposal problem to the poultry industry in many parts of the United Kingdom. The plant at Eye is a small to medium scale power station, fired using poultry litter. The 12.7 MW of electricity generated is supplied, through the local utility, to the National Grid. The spent litter that constitutes the fuel is made up of excrement and animal bedding (usually 90% excrement and 10% straw or wood shavings). It comes from large climate-controlled buildings (broiler houses) where birds, reared for meat production, are allowed to roam freely. (UK)

The World Health Organization's Global Action Plan on antimicrobial resistance (AMR) recommended monitoring of antimicrobial use (AMU) through surveillance and research to help mitigate AMR. This survey was aimed at assessing poultry owners' knowledge/awareness and practices regarding AMU, identified pathways for AMR emergence and spread in small-scale commercial poultry farms and free-range local bird flocks in North-central Nigeria. An interview questionnaire-based cross-sectional study was conducted on commercial poultry farmers and local bird flock keepers in 2017. Also, a Traffic Light system model was used assess risk status of AMU in farms and flocks. All the 384 recruited poultry farmers/keepers participated in the survey. Female respondents were the majority (67.2%). Low proportion of poultry farmers (46.4%, 89/192) and very low proportion of bird keepers (6.8%, 13/192) knew antimicrobials misuse to be when administered under dose. About 48% (93/192) of farmers and 93% (179/192) of keepers arbitrary determined antimicrobial dosage before administration. Respondents used antimicrobials for therapeutic, prophylactic, and growth promotion in birds. Also, participants significantly identified contaminated poultry products, infected poultry or contaminated formites, and discharged contaminated faeces into environment as pathways for transmission of antimicrobial resistant pathogens to humans. Traffic Light system model revealed 88.5% of small-scale commercial poultry farms to frequently used antimicrobials without veterinarians' consultations thereby attaining Class 1 (Red risk) status. The model showed that 92.1% of free-range local bird flocks rarely used antimicrobials thereby attaining Class 3 (Green risk) status. Improper antimicrobial dosage in poultry (OR: 7.23; 95% CI: 2.74, 19.21), non-enforcement of AMU regulating laws in poultry (OR: 4.12; 95% CI: 2.39, 7.10), weak financial status of poultry owners (OR: 3.00; 95% CI: 2.39, 7.10), and management

2006-05-01

A survey was conducted at a poultry feed production unit in Kuwait for mycotoxin contamination in the samples of yellow maize, soybean meal, wheat bran used as raw material and the poultry feed prepared for broiler starter, broiler finisher, and layer mash. Individual aflatoxins were determined by high-pressure liquid chromatography after immunoaffinity column purification. Repeated analysis revealed average aflatoxin concentration in maize at 0.27 ppb (range 0 to 1.69 ppb), soybean meal at 0.20 ppb (range 0 to 1.27 ppb), wheat bran at 0.15 ppb (range 0 to 1.07 ppb), prepared poultry feed for broiler starter at 0.48 ppb (range 0 to 3.26 ppb), broiler finisher at 0.39 ppb (range 0 to 1.05 ppb), and layer mash at 0.21 ppb (range 0 to 1.30 ppb). Other mycotoxins (ochratoxin, fumonisin, deoxynivalenol (DON), and zearalenone), were detected by quantitative enzyme-linked immunosorbent assay. The average levels of ochratoxin A ranged from 4.6 to 9.6 ppb, fumonisin from 1.4 to 3.2 ppm, DON from 0.17 to 0.29 ppm, and zearalenone from 46.4 to 67.6 ppb in various commodities and prepared feed samples. The study revealed the coexistence of determined mycotoxins, although their concentrations in general were found to be lower than the permissible levels, wherever defined, for the poultry feed.

The condition of the poultry industry in Poland

2014-08-01

Full Text Available The poultry industry in Poland is characterized by high dynamics of development and in this regard was placed at the forefront of European Union countries. The main reason for the acceleration and modernization of the industry was the Polish accession to the European Union. Sanitary and veterinary requirements, and rules on the placing of poultry products in the trade, which our country was obliged to fulfill, led to the sector producing products with a high level of security. Rapidly growing domestic demand and foreign markets for Polish products affectes the growth of poultry production. Consumers are attracted primarily by the high quality products and reasonable price, as well as the relatively low cost of production. The industry has become an example of what can grow even in a crisis. As a result of changes occurring in the Polish market, meat and aspecially poultry meat is becoming increasingly important, becoming an essential part of the economy. Forecasts for the poultry industry in 2014 are positive, sae to an anticipated decline in grain prices and a limited supply of pork and beef. This will increase the global and the European Union demand for white meat, due to its nutritional properties and competitive prices.

2015-01-01

This analysis was conducted to evaluate the prevalence of airway obstruction among Latino poultry processing workers. Data were collected from 279 poultry processing workers and 222 other manual laborers via spirometry and interviewer-administered questionnaires. Participants employed in poultry processing reported the activities they perform at work. Participants with forced expiratory volume in 1 second (FEV1) or FEV1/forced expiratory volume (FVC) below the lower limits of normal were categorized as having airway obstruction. Airway obstruction was identified in 13% of poultry processing workers and 12% of the comparison population. Among poultry processing workers, the highest prevalence of airway obstruction (21%) occurred among workers deboning chickens (prevalence ratio: 1.75; 95% confidence interval: 0.97, 3.15). These findings identify variations in the prevalence of airway obstruction across categories of work activities. PMID:24965321

The role of vaccination in risk mitigation and control of Newcastle disease in poultry.

Science.gov (United States)

Mayers, Jo; Mansfield, Karen L; Brown, Ian H

2017-10-20

Newcastle disease is regarded as one of the most important avian diseases throughout the world and continues to be a threat and economic burden to the poultry industry. With no effective treatment, poultry producers rely primarily on stringent biosecurity and vaccination regimens to control the spread of this devastating disease. This concise review provides an historical perspective of Newcastle disease vaccination and how fundamental research has paved the way for the development of instrumental techniques which are still in use today. Although vaccination programmes have reduced the impact of clinical disease, they have historically been ineffective in controlling the spread of virulent viruses and therefore do not always offer an adequate solution to the world's food security problems. However, the continued development of novel vaccine technology and improved biosecurity measures through education may offer a solution to help reduce the global threat of Newcastle disease on the poultry industry.

Full Text Available Introduction: Poultry is an important commodity for household consumption. In recent years, price fluctuation for this commodity has caused an uncertain condition for consumers and poultry prices over the past two years has changed a lot. This has caused many changes and uncertainty in a purchase decision. Analysis of changes and volatility modeling can be a great help to predict the poultry prices and great facilities in creating appropriate policies in future. The prices of staples such as poultry consumption basket is highly variable because much of the protein is necessary for daily energy are supplied in this way to households. So when the price of chicken which has been changed over the past two years and has always been in the press and media attention, has been selected in this study. Fluctuations in price of chicken have caused a surge in consumer expectations and contributed in volatility of chicken price. Materials and Methods: In this study ARCH models have been used for daily price of poultry of Iran’s market and this was investigated for2012-13and2013-14.BecauseARCH models can model the impact of heterogeneous variance over time in time series data then the variance of time series, which is limited in time, has no time limit. Many time series are more complex than a linear patterns, thus, non-linear models are of particular importance in Economic Sciences and Econometrics. Accordingly, Engle presented that ARCH model can model the heterogeneous variance components of the error term. That is a disturbing element and modeling can help to examine and explore the relationship between the components can be found disturbing. Basically, these models fit the data to a cluster and periodic oscillations with high volatility and low volatility associated with the period. In this study, we used several different models like ARCH, GARCH, IGARCH, and TGARCH. The distribution of the error term of the model also followt-student distribution

Coccidiostats in unmedicated feedingstuffs for poultry

Radičević, T.; Janković, S.; Stefanović, S.; Nikolić, D.; Đinović-Stojanović, J.; Spirić, D.

2017-09-01

Coccidiostats are compounds that are widely used as feed additives to prevent and treat coccidiosis, a contagious disease affecting mainly poultry, and which is associated with warm and humid conditions, as can be found on poultry farms. In Serbia and in the EU, specific coccidiostats are authorized as poultry feed additives. A wide range of these products is available for prevention (as additives) and treatment of coccidiosis (as veterinary medicinal products). The aim of this study is to present findings of residues of coccidiostats in unmedicated feed for chickens for fattening and laying hens as possible causes for coccidiostat residues in liver and eggs. The reasons for these compounds occurring in animal tissues and primary products of animal origin could be an inappropriate withdrawal period after the last administration of medicated feed or cross-contamination of unmedicated feed during the production on the same production line as medicated feedingstuffs, because of inadequate cleaning procedures and/or hygiene practices.

Thermal Inactivation of avian influenza virus in poultry litter as a method to decontaminate poultry houses.

Science.gov (United States)

Stephens, Christopher B; Spackman, Erica

2017-09-15

Removal of contaminated material from a poultry house during recovery from an avian influenza virus (AIV) outbreak is costly and labor intensive. Because AIV is not environmentally stable, heating poultry houses may provide an alternative disinfection method. The objective was to determine the time necessary to inactivate AIV in poultry litter at temperatures achievable in a poultry house. Low pathogenic (LP) AIV inactivation was evaluated between 10.0°-48.9°C, at ∼5.5°C intervals and highly pathogenic (HP) AIV inactivation was evaluated between 10.0°-43.3°C, at ∼11°C intervals. Samples were collected at numerous time points for each temperature. Virus isolation in embryonating chicken eggs was conducted to determine if viable virus was present. Each sample was also tested by real-time RT-PCR. Low pathogenicity AIV was inactivated at 1day at 26.7°C or above. At 10.0, 15.6 and 21.1°C, inactivation times increased to 2-5days. Highly pathogenic AIV followed a similar trend; the virus was inactivated after 1day at 43.3°C and 32.2°C, and required 2 and 5days for inactivation at 21.1°C and 10.0°C respectively. While low pathogenicity AIV appeared to be inactivated at a lower temperature than high pathogenicity AIV, this was not due to any difference in the strains, but due to fewer temperature points being evaluated for high pathogenicity. Endpoints for detection by real-time RT-PCR were not found even weeks after the virus was inactivated. This provides a guideline for the time required, at specific temperatures to inactivate AIV in poultry litter and likely on surfaces within the house. Heat treatment will provide an added level of safety to personnel and against further spread by eliminating infectious virus prior to cleaning a house. Published by Elsevier B.V.

2016-06-01

Full Text Available The gut is a fundamental organ system which makes up two equally important functions, i.e., the digestion and host defence. To elicit the well-functioning and healthy gut, the dynamic balance of gut ecosystem is of importance. A wide range of factors related to diets and infectious disease agents seem to affect this balance, and subsequently affect the health status and production performance of the chicken. With the ban and/or reduction of the use of antibiotic growth promoters (AGPs in poultry production, the alternatives to AGP are needed especially to preserve the balance of gut microbiota in chicken. This review provides a summary of the potentials and possible mechanisms of action of some alternatives to AGP (referred as nutraceuticals in improving the gut microbial ecosystem and immune system as well as growth performance of poultry.

Methods to address poultry robustness and welfare issues through breeding and associated ethical considerations.

Directory of Open Access Journals (Sweden)

William eMuir

Full Text Available As consumers and society in general become more aware of ethical and moral dilemmas associated with confined rearing systems, pressure is put on the animal and poultry industries to adopt alternative forms of housing. This presents challenges especially regarding managing competitive social interactions between animals. However, selective breeding programs are rapidly advancing, enhanced by both genomics and new quantitative genetic theory and offer potential solutions by improving adaptation of the bird to existing and proposed production environments. The outcomes of adaptation could lead to improvement of animal welfare by increasing fitness of the animal for the given environments, which might lead to increased contentment and decreased distress in those systems. Genomic selection, based on dense genetic markers, will allow for more rapid improvement of traits that are expensive or difficult to measure, or have a low heritability, such as pecking, cannibalism, robustness, mortality, leg score, bone strength, disease resistance, and thus has the potential to address many poultry welfare concerns. Recently selection programs to include social effects, known as associative or indirect genetic effects (IGE, have received much attention. Group, kin, multi-level and multi-trait selection have all been shown to be highly effective in reducing mortality while increasing productivity of poultry layers and reduce or eliminate the need for beak trimming. Also, multi-level selection was shown to increases robustness as indicated by l greater ability of birds to cope with stressors. Kin selection has been shown to be easy to implement and improve both productivity and animal well-being . Because social effects are improved with such programs, it might be possible to increase stocking density, increase light levels, and use larger groups in floor pens. However, such changes raise ethical concerns that may constrain making these choices.

The purpose of this project was to assess poultry grower residue, or litter (manure plus absorbent biomass), as a fuel source for Community Power Corporation's small modular biopower system (SMB). A second objective was to assess the poultry industry to identify potential ''on-site'' applications of the SMB system using poultry litter residue as a fuel source, and to adapt CPC's existing SMB to generate electricty and heat from the poultry litter biomass fuel. Bench-scale testing and pilot testing were used to gain design information for the SMB retrofit. System design approach for the Phase II application of the SMB was the goal of Phase I testing. Cost estimates for an onsite poultry litter SMB were prepared. Finally, a market estimate was prepared for implementation of the on-farm SMB using poultry litter

2017-01-01

Foodborne pathogens such as Salmonella, Campylobacter, Escherichia coli , and Listeria are a major concern within the food industry due to their pathogenic potential to cause infection. Of these, Listeria monocytogenes , possesses a high mortality rate (approximately 20%) and is considered one of the most dangerous foodborne pathogens. Although the usual reservoirs for Listeria transmission have been extensively studied, little is known about the relationship between Listeria and live poultry production. Sporadic and isolated cases of listeriosis have been attributed to poultry production and Listeria spp. have been isolated from all stages of poultry production and processing. Farm studies suggest that live birds may be an important vector and contributor to contamination of the processing environment and transmission of Listeria to consumers. Therefore, the purpose of this review is to highlight the occurrence, incidence, and potential systemic interactions of Listeria spp. with poultry.

Sit M.L.

2016-04-01

Full Text Available The gas engine driven carbon dioxide heat pump designed for providing the heat, cold and electricity for industrial poultry house is proposed. The scheme differs from the known by using recuperative heat exchanger installed between the exhaust air duct of poultry house and heat pump evaporator and the heat curtain installed on the air duct after the evaporator. The air coming into the poultry house after the regenerative heat exchanger is supplied to the heat pump gas cooler. The heat pump produces heat of the required parameters of the input air and water for watering of poultry, space heating, etc. Heat pump compressor is driven by gas engine (GPA, by natural gas or biogas. The part of the gas-piston engine heat is used for adjusting the optimal heat pump mode and for regeneration of the absorbent in an evaporative cooler. The proposed technical solution of the above scheme provides a higher COP of the heat pump. Installing of heat curtain does not require the use of non-freezing solution to prevent icing of the air outlet of heat pump evaporator. The latter allows producing, besides electric power and heat, still cold (with the use off the adsorption-refrigerating machine and provide drying air inlet evaporative cooler (if necessary.

2016-04-01

Considerable work on consumers' food safety habits has highlighted issues associated with home food preparation. However, consumer handling of foods, such as poultry, during shopping and storage has not been noted. The objective of this study was to determine consumer behaviors during purchasing and initial storage of raw poultry to determine potential cross-contamination issues. A shop-along observational study was conducted to determine actual shopping, transportation, and storage behavior of consumers who purchase raw poultry products. Neither hand sanitizer nor wipes were observed in 71% of grocery store meat sections of stores visited. Plastic bags could be found in the meat section 85% of the time, but only 25% of shoppers used the bag for their raw poultry purchases. During checkout, the poultry was bagged separately from other products 71% of the time. A majority of shoppers stored raw poultry in the original package without an additional container or overwrap. Overall, there needs to be an increase in food safety education on the handling of poultry during purchasing, transportation, and storage.

Aflatoxicosis: Lessons from Toxicity and Responses to Aflatoxin B1 in Poultry

Directory of Open Access Journals (Sweden)

Melissa S. Monson

2015-09-01

Full Text Available This review is a comprehensive introduction to the effects of poultry exposure to the toxic and carcinogenic mycotoxin aflatoxin B1 (AFB1. The relationship between AFB1 sensitivity and metabolism, major direct and indirect effects of AFB1, recent studies of gene expression and transcriptome responses to exposure, and mitigation strategies to reduce toxicity are discussed. Exposure to AFB1 primarily occurs by consumption of contaminated corn, grain or other feed components. Low levels of residual AFB1 in poultry feeds can cause reduction in growth, feed conversion, egg production, and compromised immune functions, resulting in significant economic costs to producers. Thus, AFB1 acts as a “force multiplier” synergizing the adverse effects of microbial pathogens and other agents, and factors detrimental to poultry health. Domestic turkeys (Meleagris gallopavo are one of the most sensitive animals known to AFB1 due, in large part, to a combination of efficient hepatic bioactivation by cytochromes P450 1A5 and 3A37, and deficient hepatic glutathione-S-transferase (GST-mediated detoxification. Because of their sensitivity, turkeys are a good model to investigate chemopreventive treatments and feed additives for their ability to reduce AFB1 toxicity. Transcriptome analysis (RNA-seq of turkey poults (liver and spleen has identified AFB1-induced gene expression changes in pathways of apoptosis, carcinogenesis, lipid regulation, antimicrobial activity, cytotoxicity and antigen presentation. Current research focuses on further identifying the molecular mechanisms underlying AFB1 toxicity with the goal of reducing aflatoxicosis and improving poultry health.

Fungal/mycotic diseases cause significant economic losses to the poultry industry either due to their direct infectious nature or due to production of mycotoxins, the secondary fungal metabolites produced in grains or poultry feed. Several fungi have created havoc in the poultry industry and some of them cause direct harm to human health due to their zoonotic implications. They are responsible for high morbidity and mortality, especially in young birds and cause stunted growth and diarrhea; and fatal encephalitis. Mycotic dermatitis is a possible health hazard associated with poultry houses. Mycotoxins are the leading cause of producing immunosuppression in birds, which makes them prone to several bacterial and viral infections leading to huge economic losses to the poultry industry. In comparison to bacterial and viral diseases, advances in diagnosis, treatment, prevention and control of fungal diseases in poultry has not taken much attention. Recently, molecular biological tools have been explored for rapid and accurate diagnosis of important fungal infections. Effective prevention and control measures include: appropriate hygiene, sanitation and disinfection, strict biosecurity programme and regular surveillance/monitoring of fungal infections as well as following judicious use of anti-fungal drugs. Precautionary measures during crop production, harvesting and storing and in feed mixing plants can help to check the fungal infections including health hazards of mycotoxins/mycotoxicosis. The present review describes the fungal pathogens causing diseases in poultry/birds, especially focusing to their diagnosis, prevention and control measures, which would help in formulating appropriate strategies to have a check and control on these unwanted troubles to the poultry producers/farmers.

The role of rodents in avian influenza outbreaks in poultry farms: a review.

Science.gov (United States)

Velkers, Francisca C; Blokhuis, Simon J; Veldhuis Kroeze, Edwin J B; Burt, Sara A

2017-12-01

Wild migratory birds are associated with global avian influenza virus (AIV) spread. Although direct contact with wild birds and contaminated fomites is unlikely in modern non-free range poultry farms applying biosecurity measures, AIV outbreaks still occur. This suggests involvement of other intermediate factors for virus transmission between wild birds and poultry. This review describes current evidence of the potential role of rodents in AIV transmission from wild birds to poultry and between poultry houses. Rodents can be abundant around poultry houses, share their habitat with waterfowl and can readily enter poultry houses. Survival of AIV from waterfowl in poultry house surroundings and on the coat of rodents suggests that rodents are likely to act as mechanical vector. AIVs can replicate in rodents without adaptation, resulting in high viral titres in lungs and nasal turbinates, virus presence in nasal washes and saliva, and transmission to naïve contact animals. Therefore, active AIV shedding by infected rodents may play a role in transmission to poultry. Further field and experimental studies are needed to provide evidence for a role of rodents in AIV epidemiology. Making poultry houses rodent-proof and the immediate surroundings unattractive for rodents are recommended as preventive measures against possible AIV introduction.

The applicability of Fenton's oxidation as an advanced treatment for chemical oxygen demand (COD) and color removal from anaerobically treated poultry manure wastewater was investigated. The raw poultry manure wastewater, having a pH of 7.30 ({+-}0.2) and a total COD of 12,100 ({+-}910) mg/L was first treated in a 15.7 L of pilot-scale up-flow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated for 72 days at mesophilic conditions (32 {+-} 2 deg. C) in a temperature-controlled environment with three different hydraulic retention times (HRT) of 15.7, 12 and 8.0 days, and with organic loading rates (OLR) between 0.650 and 1.783 kg COD/(m{sup 3} day). Under 8.0 days of HRT, the UASB process showed a remarkable performance on total COD removal with a treatment efficiency of 90.7% at the day of 63. The anaerobically treated poultry manure wastewater was further treated by Fenton's oxidation process using Fe{sup 2+} and H{sub 2}O{sub 2} solutions. Batch tests were conducted on the UASB effluent samples to determine the optimum operating conditions including initial pH, effects of H{sub 2}O{sub 2} and Fe{sup 2+} dosages, and the ratio of H{sub 2}O{sub 2}/Fe{sup 2+}. Preliminary tests conducted with the dosages of 100 mg Fe{sup 2+}/L and 200 mg H{sub 2}O{sub 2}/L showed that optimal initial pH was 3.0 for both COD and color removal from the UASB effluent. On the basis of preliminary test results, effects of increasing dosages of Fe{sup 2+} and H{sub 2}O{sub 2} were investigated. Under the condition of 400 mg Fe{sup 2+}/L and 200 mg H{sub 2}O{sub 2}/L, removal efficiencies of residual COD and color were 88.7% and 80.9%, respectively. Under the subsequent condition of 100 mg Fe{sup 2+}/L and 1200 mg H{sub 2}O{sub 2}/L, 95% of residual COD and 95.7% of residual color were removed from the UASB effluent. Results of this experimental study obviously indicated that nearly 99.3% of COD of raw poultry manure wastewater could be effectively removed by a

Full Text Available Aim: To document the use of indigenous plants used by family poultry rearers to treat and control diseases and parasites in 15 villages of Botswana. Materials and Methods: A total of 1000 family poultry rearers in 15 villages were interviewed using a structured questionnaire. Data were also collected through direct observation, village walks, interview of passers-by, group interviews, and meetings with key informants (i.e., traditional leaders, extension agents and chairpersons of village development committees. Results: The ethnoveterinary practices in 15 villages of Botswana were identified and documented. Nineteen plant species representing 15 families were used by family poultry rearers to treat and control poultry diseases and parasites. Most frequently used plants were from Fabaceae, Asteraceae and Liliaceae. Both human and veterinary medications (e.g., vicks, disprin and Compral tablets, blue stones, potassium permanganate, veterinary drugs and vaccines were used in health management. Sixty-six percent of the respondents said they used traditional remedies to control and treat diseases, 19% did not use vaccines or remedies, 2% used vaccines while 13% used drugs to control and treat diseases. Conclusions: Ethnoveterinary medicine predominates in family poultry healthcare. Scientific investigations should be carried out to ascertain the effectiveness of identified plant species used in health management of family poultry. [Vet World 2013; 6(1.000: 18-21

The disposal of poultry processing industry waste into the environment without proper care, can cause contamination. Agricultural monitored application is an alternative for disposal, considering its high amount of organic matter and its potential as a soil fertilizer. This study aimed to evaluate the potential of poultry processing industry waste to improve the conditions of a degraded soil from a desertification hotspot, contributing to leguminous tree seedlings growth. The study was carried out under greenhouse conditions in a randomized blocks design and a 4 × 2 factorial scheme with five replicates. The treatments featured four amounts of poultry processing industry waste (D1 = control 0 kg ha(-1); D2 = 1020.41 kg ha(-1); D3 = 2040.82 kg ha(-1); D4 = 4081.63 kg ha(-1)) and two leguminous tree species (Mimosa caesalpiniaefolia Benth and Leucaena leucocephala (Lam.) de Wit). The poultry processing industry waste was composed of poultry blood, grease, excrements and substances from the digestive system. Plant height, biomass production, plant nutrient accumulation and soil organic carbon were measured forty days after waste application. Leguminous tree seedlings growth was increased by waste amounts, especially M. caesalpiniaefolia Benth, with height increment of 29.5 cm for the waste amount of 1625 kg ha(-1), and L. leucocephala (Lam.) de Wit, with maximum height increment of 20 cm for the waste amount of 3814.3 kg ha(-1). M. caesalpiniaefolia Benth had greater initial growth, as well as greater biomass and nutrient accumulation compared with L. leucocephala (Lam.) de Wit. However, belowground biomass was similar between the evaluated species, resulting in higher root/shoot ratio for L. leucocephala (Lam.) de Wit. Soil organic carbon did not show significant response to waste amounts, but it did to leguminous tree seedlings growth, especially L. leucocephala (Lam.) de Wit. Poultry processing industry waste contributes to leguminous tree seedlings growth

Cassity-Duffey, Kate; Cabrera, Miguel; Mowrer, Jake; Kissel, David

2015-07-01

The pH value of poultry litter is affected by nitrification, mineralization, and the addition of acidifying chemicals, all acting on the poultry litter pH buffering capacity (pHBC). Increased understanding of poultry litter pHBC will aid in modeling NH volatilization from surface-applied poultry litter as well as estimating rates of alum applications. Our objectives were to (i) determine the pHBC of a wide range of poultry litters; (ii) assess the accuracy of near-infrared reflectance spectroscopy (NIRS) for determining poultry litter pHBC; and (iii) demonstrate the use of poultry litter pHBC to increase the accuracy of alum additions. Litter pHBC was determined by titration and calculated from linear and sigmoidal curves. For the 37 litters measured, linear pHBC ranged from 187 to 537 mmol (pH unit) kg dry litter. The linear and sigmoidal curves provided accurate predictions of pHBC, with most > 0.90. Results from NIRS analysis showed that the linear pHBC expressed on an "as is" water content basis had a NIRS coefficient of calibration (developed using a modified partial least squares procedure) of 0.90 for the 37 poultry litters measured. Using the litter pHBC, an empirical model was derived to determine the amount of alum needed to create a target pH. The model performed well in the range of pH 6.5 to 7.5 (RMSE = 0.07) but underpredicted the amount of alum needed to reach pH litter, which prevented its hydrolysis.

Implementation of Haccp in the Mexican Poultry Processing Industry

Science.gov (United States)

Maldonado-Siman, Ema; Martínez-Hernández, Pedro Arturo; Ruíz-Flores, Agustín; García-Muñiz, José G.; Cadena-Meneses, José A.

Hazard Analysis and Critical Control Point (HACCP) is a safety and quality management tool used as major issue in international and domestic trade in food industry. However, detailed information on costs and benefits of HACCP implementation is needed to provide appropriate advice to food processing plants. This paper reports on the perceptions of costs and benefits by the Mexican poultry processing plants and sale destinations. The results suggest that the major costs of implementing and operating HACCP within poultry processing plants are record keeping and external technical advice. The main benefit indicated by the majority of processing plants is a reduction in microbial counts. Over 39% of poultry production is sent to nation-wide chains of supermarkets, and less than 13% is sent to international markets. It was concluded that the adoption of HACCP by the Mexican poultry processing sector is based on the concern to increase and keep the domestic market, rather than to compete in the international market.

2002-05-01

The development of new methods of administering coccidiosis vaccines has facilitated their use in the hatchery and thereby improved prospects for the economic vaccination of broilers. The acquisition of protective immunity to Eimeria species is boosted by further exposure to infection after vaccination. Factors that affect the reproductive efficiency of non-attenuated and attenuated vaccines are considered and the key role that oocyst production plays in establishing and maintaining uniform immunity in a flock of chickens is discussed. In addition to immunisation, a possible advantage to the application of certain vaccines is that their use could repopulate poultry houses with drug-sensitive organisms. Theoretical rotation programmes in which the use of drugs is alternated with that of vaccines are described. Variability of the cross-protective immune response between strains of the same species should be considered during vaccine development and subsequent use. The significance of less common species of Eimeria, not included in all vaccines, also needs to be assessed. An important consideration is the occurrence of pathogens other than Eimeria (such as the bacterium Clostridium) in flocks given coccidiosis vaccines and the methods by which they might be controlled. More research is required into the relationship between bacterial and viral infections of poultry and coccidiosis vaccination. Vaccines need to be developed that are simple to apply and cost effective for use in areas of the world where small-scale poultry production is commonplace. In the near future it is likely that more live vaccines based upon oocysts derived from attenuated strains of Eimeria will be developed but in the longer term vaccines will be based on the selective presentation to the host of specific molecules that can induce protective immunity. This achievement will require significant investment from the private and public sectors, and, if successful, will facilitate the sustainable

Poultry management: a useful tool for the control of necrotic enteritis in poultry.

Science.gov (United States)

Tsiouris, Vasilios

2016-06-01

The intestinal ecosystem of poultry has been inevitably changed as a result of the ban of antimicrobial growth promoters. The re-emergence of necrotic enteritis has been the most significant threat for the poultry industry, which, in clinical form, causes high mortality and in subclinical forms, affects growth and feed conversion. It is one of the most common and economically devastating bacterial diseases in modern broiler flocks in terms of performance, welfare and mortality. Necrotic enteritis is a multi-factorial disease process, in which a number of co-factors are usually required to precipitate an outbreak of the disease. Although, Clostridium perfringens has been identified as the aetiological agent of the disease, the predisposing factors that lead to over-proliferation of C. perfringens and the subsequent progression to disease are poorly understood. Any factor that causes stress in broiler chicks could suppress the immune system and disturb the balance of the intestinal ecosystem, in such a way that the risk of a necrotic enteritis (NE) outbreak increases. Poultry management could significantly affect the pathogenesis of NE. In particular, feed restriction and coccidiosis vaccination can protect against NE, while extreme house temperature, feed mycotoxins and high stocking density predispose to NE. It becomes really important to understand the pathogenesis of the disease, as well as to clarify the interactions between husbandry, nutritional and infectious factors and the outbreak of necrotic enteritis. This is necessary and extremely important in order to develop managerial strategies at the farm level to control the incidence and severity of the disease in the post-antibiotic era.

Supplying the energy demand in the chicken meat processing poultry with biogas

Directory of Open Access Journals (Sweden)

Adriano Henrique Ferrarez

2016-01-01

Full Text Available The main use of electrical energy in the chicken meat processing unit is refrigeration. About 70% of the electricity is consumed in the compressors for the refrigeration system. Through this study, the energetic viability of using biogas from poultry litter in supplying the demand for the refrigeration process was found. The meat processing unit studied has the potential to process about a hundred and sixty thousand chickens a day. The potential biogas production from poultry litter is 60,754,298.91 m3.year-1. There will be a surplus of approximately 8,103MWh per month of electric energy generated from biogas. An economic analysis was performed considering a planning horizon of 20 years and the discount rate of 12% per year. The economic analysis was performed considering scenario 1: sale of all electricity generated by the thermoelectric facility, and scenario 2: sale of the surplus electricity generated after complying with the demands of the refrigeration process and all other electrical energy and thermal energy use. Economic indicators obtained for scenarios 1 and 2 were favorable for the project implementation.

Effect of irradiation on erythromycin residues in poultry meat

International Nuclear Information System (INIS)

Mazurowski, P.

1993-01-01

Ionising radiation in doses used for radurisation (Recommendations of international organizations admit for poultry meat doses up to 5 kGy. Practically doses up to 3 kGy are applied does not influence erythromycin concentration in poultry meat. Doses on a level 10 kGy reduce its concentration in slurry more effectively, but results of earlier studies on penicillin and streptomycin suggest, that reduction of erythromycin level in meat should be smaller than in slurry. This allows an assumption that poultry meat irradiation with radurisation doses (up to 5 kGy), does not cause danger of overlooking of erythromycin residues in meat, with traditional, microbiological methods of detection.

Gamma irradiation, through its ability to inactivate microorganisms, has been shown to effectively extend the shelf life of commercially slaughtered chickens from 2-4 d to 14-21 d under normal refrigeration temperatures. Although a high percentage of carcasses were contaminated with Salmonella, the level of contamination was relatively low; the doses applied for shelf-life extention thus also served to eliminate this pathogen. Even when carcasses were artificially inoculated with Salmonella of levels several orders of magnitude higher than normal, the recommended radiation doses (3 or 5 kGy) were still capable of rendering the product 'pathogen free'. Irradiated poultry could not be distinguished organoleptically from control samples, even when twice the maximum recommended dose was applied. In conclusion, the irradiation of commercially produced poultry in South Africa with relatively low doses can be of significant benefit by (1) markedly extending the acceptable shelf life and (2) eliminating pathogenic bacteria present on the commercially available product [af

Aflatoxins (AF) are toxic fungal secondary metabolites and are known mycotoxins pathological to animals and humans. Poultry litter is frequently used as a food supplement for ruminants, and when poultry feed contains AF, the litter becomes contaminated as well, thus having an effect on livestock health. This study identified and quantified AF (AFB(1), AFB(2), AFG(1), and AFG(2)) from poultry feed and their recovery, together with their metabolites (AFM(1), AFM(2), AFP(1), and aflatoxicol) in litter. An experiment with 25 Hy-Line W-36 hens, in their second production stage, 121 wk old, was carried out. Hens were distributed in 3 groups placed in individual cages and 1 ration of 250 g of feed was given to each hen daily. Nine hens of the control group were fed with clean feed, without AFB(1); the other 2 experimental groups, with 8 hens each, were fed with 2 AFB(1) concentrations: 30 and 500 microg.kg(-1). The feed was replaced and weighed daily throughout a 7-d period to register the amount of feed consumed by the hens. Litter from each hen was collected, weighed, and dried individually. The chemical analysis of 40 g of each one of the 200 feed and 200 litter samples was chemically extracted and concentrated with immunoaffinity columns for total AF. To quantify AF, calibration curves for each AF were done by HPLC. Feed samples of the 3 groups presented significant difference with AFB(2) and AFG(2), whereas in litter samples, there were significant differences for AFG(2) in the 500 microg.kg(-1) group. Poultry litter had traces of AFM(1), AFM(2), AFP(1), and AFL with no significant differences among treatments. Aflatoxin B(1) prevalence in litter samples can cause damages in livestock because this mycotoxin reduces the digestibility of ruminant feed up to 67%.

Ammonia production in poultry houses can affect health of humans, birds, and the environment-techniques for its reduction during poultry production.

Naseem, Sadia; King, Annie J

Due to greater consumption of poultry products and an increase in exports, more poultry houses will be needed. Therefore, it is important to investigate ways that poultry facilities can coexist in close proximity to residential areas without odors and environmental challenges. Ammonia (NH 3 ) is the greatest concern for environmental pollution from poultry production. When birds consume protein, they produce uric acid, ultimately converted to NH 3 under favorable conditions. Factors that increase production include pH, temperature, moisture content, litter type, bird age, manure age, relative humidity, and ventilation rate (VR). NH 3 concentration and emissions in poultry houses depend on VR; seasons also have effects on NH 3 production. Modern ventilation systems can minimize NH 3 in enclosed production spaces quickly but increase its emissions to the environment. NH 3 adversely affects the ecosystem, environment, and health of birds and people. Less than 10 ppm is the ideal limit for exposure, but up to 25 ppm is also not harmful. NH 3 can be minimized by housing type, aerobic and anaerobic conditions, manure handling practices, litter amendment, and diet manipulation without affecting performance and production. Antibiotics can minimize NH 3 , but consumers have concerns about health effects. Administration of probiotics seems to be a useful replacement for antibiotics. More studies have been conducted on broilers, necessitating the need to evaluate the effect of probiotics on NH 3 production in conjunction with laying hen performance and egg quality. This comprehensive review focuses on research from 1950 to 2018.

2002-01-01

A survey form provided by the Joint FAO/IAEA Division was used to collect data on village poultry production in the Sudan. The production system in the households was based on scavenging indigenous domestic chickens, at times accompanied by pigeons, guinea fowls, ducks or turkeys. The average flock size was 18.8 birds and included 44.3% hens, 10% cocks, 20% growers and 24.8% chicks. The hen to cock ratio was 4.4:1. Average egg production was 3.1 per hen per month, of which 76% were incubated by hens. About 78% of incubated eggs hatched of which 75% survived the brooding period. Approximately half of the households provided the chickens with housing. Around 25.7% of interviewed households used chicken manure as fertilizer. While scavenging, chickens fed on insects, grass, vegetables and kitchen wastes. Feed supplements included sorghum, millet and sometimes wheat bran and alfalfa. The ownership of village chickens was shared between all gender categories and all were involved in the management of the birds. The major constraints to village poultry production in the Sudan were identified and included inadequate health care, poor production, inappropriate housing and poor knowledge of poultry management.

Craft, David L.; Hong, Theodore S.; Shih, Helen A.; Bortfeld, Thomas R.

2012-01-01

Purpose: To test whether multicriteria optimization (MCO) can reduce treatment planning time and improve plan quality in intensity-modulated radiotherapy (IMRT). Methods and Materials: Ten IMRT patients (5 with glioblastoma and 5 with locally advanced pancreatic cancers) were logged during the standard treatment planning procedure currently in use at Massachusetts General Hospital (MGH). Planning durations and other relevant planning information were recorded. In parallel, the patients were planned using an MCO planning system, and similar planning time data were collected. The patients were treated with the standard plan, but each MCO plan was also approved by the physicians. Plans were then blindly reviewed 3 weeks after planning by the treating physician. Results: In all cases, the treatment planning time was vastly shorter for the MCO planning (average MCO treatment planning time was 12 min; average standard planning time was 135 min). The physician involvement time in the planning process increased from an average of 4.8 min for the standard process to 8.6 min for the MCO process. In all cases, the MCO plan was blindly identified as the superior plan. Conclusions: This provides the first concrete evidence that MCO-based planning is superior in terms of both planning efficiency and dose distribution quality compared with the current trial and error–based IMRT planning approach.

Population Dynamics of Salmonella enterica Serotypes in Commercial Egg and Poultry Production ▿

Fresh and processed poultry have been frequently implicated in cases of human salmonellosis. Furthermore, increased consumption of meat and poultry has increased the potential for exposure to Salmonella enterica. While advances have been made in reducing the prevalence and frequency of Salmonella contamination in processed poultry, there is mounting pressure on commercial growers to prevent and/or eliminate these human pathogens in preharvest production facilities. Several factors contribute to Salmonella colonization in commercial poultry, including the serovar and the infectious dose. In the early 1900s, Salmonella enterica serovars Pullorum and Gallinarum caused widespread diseases in poultry, but vaccination and other voluntary programs helped eradicate pullorum disease and fowl typhoid from commercial flocks. However, the niche created by the eradication of these serovars was likely filled by S. Enteritidis, which proliferated in the bird populations. While this pathogen remains a significant problem in commercial egg and poultry production, its prevalence among poultry has been declining since the 1990s. Coinciding with the decrease of S. Enteritidis, S. Heidelberg and S. Kentucky have emerged as the predominant serovars in commercial broilers. In this review, we have highlighted bacterial genetic and host-related factors that may contribute to such shifts in Salmonella populations in commercial poultry and intervention strategies that could limit their colonization.

In 2007 and 2008, a monitoring study was carried out in Poland to examine the occurrence of thermotolerant Campylobacter spp. in raw and cooked chicken products available on the retail market. A total of 912 samples were tested: 443 samples of raw chicken meat, 146 samples of giblets, and 323 ready-to-eat poultry products (150 samples of spit-roasted chicken, 56 samples of smoked chicken, and 117 samples of pâté and cold meats). A high level of contamination of raw chicken meat (51.7% of samples) and chicken giblets (47.3% of samples) was detected. However, thermotolerant Campylobacter spp. were found in only 1.2% of the ready-to-eat poultry products.

1997-01-01

The aim of study was to evaluate the quality of poultry meat, roasted and smoked chicken and poultry pie packing under low and high vacuum. All investigated products were stored at +4 degrees C and evaluated by microbiological analysis. It was showed that packing under low and high vacuum inhibited development of aerobic microorganisms, proteolytic bacteria, yeasts and moulds. Vacuum-packaged storage of poultry meat and its products stimulated activity of anaerobic, nonsporeforming bacteria. The fast spoilage of fresh poultry meat was observed both under vacuum and conventional storage. The microbiology quality of poultry products depended on technology of production and microbiological quality of raw material.

Study of the acceleration of ammonia generation process from poultry residues aiming at hydrogen production

International Nuclear Information System (INIS)

Egute, Nayara dos Santos

2010-01-01

The hydrogen, utilized in fuel cells, can be produced from a variety of intermediate chemicals, between them, the ammonia. The ammonia gas as a raw material for the hydrogen production has been used due to its high energetic content, facility of decomposition, high availability, low prices, low storage pressure and its by-products are environmentally correct. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. The residue from the poultry-rearing farms is the broiler litter and from the egg production system is the excreta without any substrate. The characterization of these residues was performed using the Wavelength-Dispersive X-Ray Fluorescence (WDXRF), Elementary Analysis (CHN), Thermogravimetry and GC/MS - Gas chromatography/ Mass spectrometry. The studied factors which influence the ammonia volatilization were: nitrogen content, raising period, urease enzyme, temperature, pH and moisture content. The experiment results with poultry litter and excreta allow to conclude that the manipulation of the following parameters increased the ammonia emission: pH, nitrogen content, raising period, age of birds and excreta accumulation, urease enzyme and the temperature. The addition of different amounts of sand in the excreta and different volumes of water in the poultry litter inhibited the emission of ammonia. The variation of the quantity of material (broiler litter or excreta) and the volume of the flask used as incubator chamber showed no significant alterations to be chosen as a variable. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined in this material. Due to the large amount of poultry litter and excreta from the production processes, the reuse of poultry residues to obtain ammonia is necessary to improve the quality of the local

Fotidis, Ioannis A; Kougias, Panagiotis G; Zaganas, Ioannis D; Kotsopoulos, Thomas A; Martzopoulos, Gerasimos G

2014-01-01

Poultry manure is an ammonia-rich substrate due to its high content of proteins and amino acids. Ammonia is the major inhibitor of anaerobic digestion (AD) process, affecting biogas production and causing great economic losses to the biogas plants. In this study, the effect of different natural zeolite dosages on the mesophilic AD of poultry manure inoculated with a non-acclimatized to ammonia inoculum (dairy manure) was investigated. Additionally, a comparative analysis was performed between the data extracted from this study and the results of a previous study, which has been conducted under the same experimental conditions but with the use of ammonia acclimatized inoculum (swine manure). At 5 and 10 g zeolite L(-1), the methane yield of poultry manure was 43.4% and 80.3% higher compared with the experimental set without zeolite addition. However, the ammonia non-acclimatized inoculum was not efficient in digesting poultry manure even in the presence of 10 g zeolite L(-1), due to low methane production (only 39%) compared with the maximum theoretical yield. Finally, ammonia acclimatized inoculum and zeolite have demonstrated a possible 'synergistic effect', which led to a more efficient AD of poultry manure. The results of this study could potentially been used by the biogas plant operators to efficiently digest poultry manure.

Update on the bird-egg syndrome and genuine poultry meat allergy.

Science.gov (United States)

Hemmer, Wolfgang; Klug, Christoph; Swoboda, Ines

Allergy to poultry meat is rare and affects both children and adults. The prevalence of poultry meat allergy is unknown, but presumably is similar to that of red meat allergy. There is no close relationship between allergy to poultry meat and allergy to red meat. Poultry meat allergy may present as primary (genuine) food allergy or as secondary food allergy resulting from cross-reactivity. Secondary poultry meat allergy may arise in the context of bird-egg-syndrome, which is due to sensitization to serum albumins present in many tissues including muscle tissue and egg yolk (Gal d 5). Primary sensitization to serum albumin may happen via the respiratory tract through exposure to pet birds (mainly in adults) or within the context of egg allergy in early childhood. Due to the heat lability of serum albumins, reactions are often limited to the skin upon contact with raw meat. Symptoms from meat ingestion are rare and mostly mild, whereas systemic reactions are common after ingestion of raw or soft-boiled egg yolk. Primary poultry meat allergy is mainly seen in adolescents and young adults, though hypersensitivity may have started already at (pre)school age. Egg allergy is usually absent. Typical symptoms of primary poultry meat allergy include OAS (±dyspnea), gastrointestinal complaints, urticaria and angioedema. Severe anaphylaxis with cardiovascular symptoms is rare. Chicken and turkey meat are highly cross-reactive and responsible for most reactions, while duck and goose meat causes milder or no symptoms. Soups, sausages, and ham represent relevant allergen sources, too. Patients with poultry meat allergy unexpectedly often suffer from concomitant allergy to fish and possibly shrimp. Serum specific IgE against fish and shrimp is found in respectively 60 and 40 % of sera, suggestive of cross-reactive allergens in these foods. The allergens thus far recognized in genuine poultry meat are LMW proteins of 5-25 kDa. One of them has been identified as �

Poultry litter and compost can alter the moisture holding capacity of a soil. These organic materials can also increase the nutrient status of a soil during the decomposition process by microbial actions. The objective of this study was to evaluate the effect of poultry litter and compost on the dielectric constant and moisture holding capacity of soil. The Delta-T theta-probe was used to measure volumetric soil water content and the apparent dielectric constant of the upper 6-cm of the soil profile. Soil texture, pH, and organic matter were also determined for each plot. Results of these analyses indicated that the pH of the soil ranged from 6.4 to 7.7 and the volumetric soil moisture content ranged from 0.06 to 0.18 cu m/cu m for the upper 6-cm of the soil profile. The effect of poultry litter and compost on soil properties resulted in an increase in the volumetric moisture content and dielectric constant of the soil due to the improvement of the soil structure.

Compression planning for continuous improvement in quality programs

International Nuclear Information System (INIS)

Willis, Y.A.; Hood, F.C.

1992-01-01

This paper describes Compression Planning, an innovative approach for planning in groups. This participative and structured approach is especially suitable for technical and highly regulated organizations. Compression Planning was applied to the first organization-wide effort at training integration for regulatory compliance, at Battelle Pacific Northwest Laboratory (PNL), a multi-program national laboratory. The planning process was judged as measurably superior to PNL's customary planning. Within 10 days a training policy was issued and an action plan drafted. The participants produced a report identifying and prioritizing 33 key training issues; began to data gather and solicit input from personnel Lab-wide, producing a 2-volume training inventory; and formulated 14 recommendations for implementation. Two years later the plan is still evolving, as PNL training continues to develop, consistent with Continuous Improvement Process objectives

Kelleher, B P; Leahy, J J; Henihan, A M; O'Dwyer, T F; Sutton, D; Leahy, M J

2002-05-01

The land disposal of waste from the poultry industry and subsequent environmental implications has stimulated interest into cleaner and more useful disposal options. The review presented here details advances in the three main alternative disposal routes for poultry litter, specifically in the last decade. Results of experimental investigations into the optimisation of composting, anaerobic digestion and direct combustion are summarised. These technologies open up increased opportunities to market the energy and nutrients in poultry litter to agricultural and non-agricultural uses. Common problems experienced by the current technologies are the existence and fate of nitrogen as ammonia, pH and temperature levels, moisture content and the economics of alternative disposal methods. Further advancement of these technologies is currently receiving increased interest, both academically and commercially. However, significant financial incentives are required to attract the agricultural industry.

Mycotoxin-contaminated feed is very dangerous for the growth and even life of poultry. The objective of the current study was to investigate the efficacy of ultra-violet irradiation for decontamination of ochratoxin A (OTA) in spiked and naturally contaminated poultry feed samples. Spiked and naturally contaminated feed samples were irradiated with ultra-violet light (UV) at distance of 25 cm over the feed samples. In vitro, the effect of UV intensity (0.1 mW cm(-2) at 254 nm UV-C) on different types of poultry feeds contaminated with OTA was evaluated. The same samples were also irradiated with sunlight and analysed for OTA by an indirect enzyme linked immunosorbent assay method. Poultry feed samples containing 500 µg kg(-1) were 100% decontaminated in 180 min with UV radiation while OTA was decreased to 70-95 µg kg(-1) using the same poultry feed samples after 8 h sunlight irradiation. Therefore, UV light was found to be more effective. Only 1 h of UV irradiation was found to be sufficient to bring the OTA level to the maximum regulatory limit suggested for poultry feeds (100 µg kg(-1) ), while 8 h were needed to obtain this level using sunlight radiations. The proposed approach is a viable option to reduce the level of OTA in contaminated poultry feeds. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Purpose: To evaluate the dosimetric difference between a simple radiation therapy plan utilizing a single contour and a more complex three-dimensional (3D) plan utilizing multiple contours, lung inhomogeneity correction, and dose-based compensators. Methods and Materials: This is a study of the radiation therapy (RT) plans of 85 patients with early breast cancer. All patients were considered for breast-conserving management and treated by conventional tangential fields technique. Two plans were generated for each patient. The first RT plan was based on a single contour taken at the central axis and utilized two wedges. The second RT plan was generated by using the 3D planning system to design dose-based compensators after lung inhomogeneity correction had been made. The endpoints of the study were the comparison between the volumes receiving greater than 105% and greater than 110% of the reference dose, as well as the magnitude of the treated volume maximum dose. Dosimetric improvement was defined to be of significant value if the volume receiving > 105% of one plan was reduced by at least 50% with the absolute difference between the volumes being 5% or greater. The dosimetric improvements in 49 3D plans (58%) were considered of significant value. Patients' field separation and breast size did not predict the magnitude of improvement in dosimetry. Conclusion: Dose-based compensator plans significantly reduced the volumes receiving > 105%, >110%, and volume maximum dose.

Market and plan characteristics related to HMO quality and improvement.

Scanlon, Dennis P; Swaminathan, Shailender; Chernew, Michael; Lee, Woolton

2006-12-01

Existing research on health plan performance examines whether variation in plans' scores is related to enrollee and health plan traits, primarily using cross-sectional research designs. This study extends that literature by incorporating data on market characteristics using a longitudinal framework. We estimate multivariate growth models that relate plan performance on standard measures to market and HMO characteristics using an unbalanced panel of data for 1998 to 2002. We find that HMO competition is not associated with better performance or greater rates of improvement in performance on the HEDIS chronic care measures. HMO penetration, on the other hand, is positively associated with HEDIS performance in several of the chronic care process-and-outcomes measures but not with a greater rate of improvement through time. Our analysis indicates that a significant percentage of the unexplained variation in quality improvement is because of permanent, unobserved plan-level characteristics that future research should strive to identify.

Chlamydia psittaci causes respiratory disease in poultry and can be transmitted to humans. Historical outbreaks of psittacosis in poultry workers indicated the need for higher awareness and an efficient risk assessment and management. This group reviewed relevant previous research, practical guidelines, and European directives. Subsequently, basic suggestions were made on how to assess and manage the risk of psittacosis in poultry processing plants based on a classical four-step approach. Collective and personal protective measures as well as the role of occupational medicine are described. Despite the finding that exposure is found in every branch, abattoir workstations seem to be associated with the highest prevalence of psittacosis. Complete eradication is difficult to achieve. Ventilation, cleaning, hand hygiene, and personal protective equipment are the most important protective measures to limit and control exposure to C. psittaci. Adequate information, communication, and health surveillance belong to the responsibilities of the occupational physician. Future challenges lay in the rigorous reporting of infections in both poultry and poultry workers and in the development of an avian and human vaccine.

Perioperative care is complex and involves multiple interconnected subsystems. Delayed starts, prolonged cases and overtime are common. Surgical procedures account for 40-70% of hospital revenues and 30-40% of total costs. Most planning and scheduling in healthcare is done without modern planning tools, which have potential for improving access by assisting in operations planning support. We identified key planning scenarios of interest to perioperative leaders, in order to examine the feasibility of applying combinatorial optimization software solving some of those planning issues in the operative setting. Perioperative leaders desire a broad range of tools for planning and assessing alternate solutions. Our modeled solutions generated feasible solutions that varied as expected, based on resource and policy assumptions and found better utilization of scarce resources. Combinatorial optimization modeling can effectively evaluate alternatives to support key decisions for planning clinical workflow and improving care efficiency and satisfaction.

Objective To determine the prevalence of carpal tunnel syndrome (CTS) in Latino poultry processing workers. Methods Symptoms and nerve conduction studies were used to prospectively assess 287 Latino poultry processing workers and 226 Latinos in other manual labor occupations. Results The prevalence of CTS was higher in poultry processing (8.7%) compared to non-poultry manual workers (4.0%, p poultry workers was 2.51 (95% CI of 1.80 to 3.50) compared to non-poultry workers. Within the poultry workers, those who performed packing, sanitation, and chilling had a trend toward less CTS than those who performed tasks requiring more repetitive and strenuous hand movements. Discussion Latino poultry processing workers have a high prevalence of CTS, which likely results from the repetitive and strenuous nature of the work. PMID:22258161

Full Text Available Poultry meat production has doubled in past 40 years in the world, with the tendency of constant growth, and its production volume exceeds beef, but is behind pork production. For poultry meat production it is typical that its annual increase exceeds pork as well as beef production. The biggest producers of poultry meat are Asia, North and South America and Europe. The most significant category of poultry is meat of young chicken (broilers. Cobb, Ross and Hubbard broiler provenance are most common in Serbia. The objective of this investigation was to analyse poultry meat production volume in Serbia, observed during three six-years periods - A (1984-1989, B (1994-1999 i C (2004-2009. For data processing there were used the data obtained from Statistical Yearbooks of Serbia from 1984. to 2009. It was found out that average poultry meat production in period A was 108,33 ± 7,00 thousand tonnes, than it statistically significantly decreased and in period B it was 76,67±5,54 thousand tonnes, and finally in period C it was 72,17± 5,78 thousand tonnes.

Full Text Available Poultry farming is a strategic branch of the livestock sector with high potential recovery in a short period of time. Today poultry farming in our country is developed in three basic systems: industrial-intensive, household-intensive and household-extensive, more importance and priority being given to intensive-industry system, the share of which in the production of eggs and meat consumption, is 50-60% of the total volume of poultry production. Intensive-industrial system is characteristic of poultry factories using biological material with valuable productive potential, are equipped with modern technological equipment, which ensures increasing the rate of production and delivery of eggs and meat, poultry achieve high production, reducing costs per unit production. In this system annually will produce 25-30 thousand tons of meat, 280-350 million eggs for consumption, including 100-150 million eggs for export. The household-intensive system is specific for small and medium farms is characteristic of which optimal dimension is considered of 1-10 thousand laying hens or up to 20-40 thousand chickens bred for meat. Household-extensive system is specific for individual poultry farms; the production obtained was mainly used to ensure family needs.

2017-10-01

To evaluate the efficacy for consumers of two potential enhancements to the Medicare Plan Finder (MPF)-a simplified data display and a "quick links" home page designed to match the specific tasks that users seek to accomplish on the MPF. Participants (N = 641) were seniors and adult caregivers of seniors who were recruited from a national online panel. Participants browsed a simulated version of the MPF, made a hypothetical plan choice, and reported on their experience. Participants were randomly assigned to one of eight conditions in a fully factorial design: 2 home pages (quick links, current MPF home page) × 2 data displays (simplified, current MPF display) × 2 plan types (stand-alone prescription drug plan [PDP], Medicare Advantage plan with prescription drug coverage [MA-PD]). The quick links page resulted in more favorable perceptions of the MPF, improved users' understanding of the information, and increased the probability of choosing the objectively best plan. The simplified data display resulted in a more favorable evaluation of the website, better comprehension of the displayed information, and, among those choosing a PDP only, an increased probability of choosing the best plan. Design enhancements could markedly improve average website users' understanding, ability to use, and experience of using the MPF. © Health Research and Educational Trust.

Singh, Kaushlendra; Risse, L Mark; Das, K C; Worley, John; Thompson, Sidney

2010-07-01

Raw poultry litter has certain drawbacks for energy production such as high ash and moisture content, a corrosive nature, and low heating values. A combined solution to utilization of raw poultry litter may involve fractionation and pyrolysis. Fractionation divides poultry litter into a fine, nutrient-rich fraction and a coarse, carbon-dense fraction. Pyrolysis of the coarse fraction would remove the corrosive volatiles as bio-oil, leaving clean char. This paper presents the effect of fractionation and pyrolysis process parameters on the calorific value of char and on the characterization of bio-oil. Poultry litter samples collected from three commercial poultry farms were divided into 10 treatments that included 2 controls (raw poultry litter and its coarse fraction having particle size greater than 0.85 mm) and 8 other treatments that were combinations of three factors: type (raw poultry litter or its coarse fraction), heating rate (30 or 10 degrees C/min), and pyrolysis temperature (300 or 500 degrees C). After the screening process, the poultry litter samples were dried and pyrolyzed in a batch reactor under nitrogen atmosphere and char and condensate yields were recorded. The condensate was separated into three fractions on the basis of their density: heavy, medium, and light phase. Calorific value and proximate and nutrient analysis were performed for char, condensate, and feedstock. Results show that the char with the highest calorific value (17.39 +/- 1.37 MJ/kg) was made from the coarse fraction at 300 degrees C, which captured 68.71 +/- 9.37% of the feedstock energy. The char produced at 300 degrees C had 42 +/- 11 mg/kg arsenic content but no mercury. Almost all of the Al, Ca, Fe, K, Mg, Na, and P remained in the char. The pyrolysis process reduced ammoniacal-nitrogen (NH4-N) in char by 99.14 +/- 0.47% and nitrate-nitrogen (NO3-N) by 95.79 +/- 5.45% at 500 degrees C.

Turmeric (Curcuma Longa: An Underutilized Phytogenic Additive in Poultry Nutrition

Directory of Open Access Journals (Sweden)

Olumuyiwa Joseph Olarotimi

2018-02-01

Full Text Available The aim of this review paper is to explore the available information from research findings on the use of Turmeric (Curcuma longa as a reliable phytogenic antibiotic for poultry production in the tropics especially in Nigeria and other countries. A wide range of phytogenic additives has found a growing interest in fortification of poultry diets. Supplementation of natural alternatives to antibiotic growth promoters in order to maintain both birds’ performance and health in the tropics will be a welcome development. Turmeric has reportedly been widely supplemented in poultry diets as natural alternative antibiotics in several studies with outstanding performances. The nutritional, medicinal, haematological and phyto-toxicological effects of turmeric were reviewed in this paper. Hence, turmeric supplementation at recommended inclusion rate in poultry feeds without posing any deleterious effects to the birds’ performances as well as the consumers of the products, and ultimately, leading to better profitability on the part of the farmers, will be a nutritional breakthrough for the farmers in the tropics.

Comparative analysis of family poultry production in twelve African countries

International Nuclear Information System (INIS)

Goodger, W.J.; Bennett, T.B.; Dwinger, R.H.

2002-01-01

The purpose of the research was to conduct a survey on family poultry to obtain information on disease prevalence, feeding practices, and the management of poultry housing in twelve African countries. The survey data were collected during both the wet and dry seasons and summarised (average and standard deviation) by country, village/region, season, and survey question. The disease data results show that three (greenish/bloody diarrhoea, swollen head, and coughing) of top four reported symptoms are part of Newcastle disease's presenting signs. Chick mortality was also higher in the wet season, when there is a higher incidence of Newcastle disease. This was also supported by the individual country data in that those countries with high chick mortality data also had low hatchability in the wet season with Egypt being the only exception. The types of housing used for shelter for family poultry was quite variable and presented a challenge to determine the level of cleaning/sanitation to assist in controlling Newcastle disease. On the one hand, a large percentage of households reported never cleaning the poultry house (e.g., Cameroon, Morocco, Mauritius, and Sudan). On the other hand, 34% of the responses to housing type were either trees or other forms of housing that would be difficult to clean i.e., old car, fence, surrounding wall, etc. Obviously, these results should be closely examined when instituting control programs for Newcastle disease. The large variety of available scavenged feed without any data on intake raises the question of how to balance the ration for the flock. Family poultry scientists need to determine a method to estimate intake which could assist in determining what supplementary feed is necessary if any. This challenge may be one of the most important aspects to family poultry management because of the importance of nutrition to poultry production with the added difficulty of providing balanced nutrition in an extensive system.

Purpose: To evaluate the effectiveness of an automated plan check tool to improve first-time plan quality as well as standardize and document performance of physics plan checks. Methods: The Plan Checker Tool (PCT) uses the Eclipse Scripting API to check and compare data from the treatment planning system (TPS) and treatment management system (TMS). PCT was created to improve first-time plan quality, reduce patient delays, increase efficiency of our electronic workflow, and to standardize and partially automate plan checks in the TPS. A framework was developed which can be configured with different reference values and types of checks. One example is the prescribed dose check where PCT flags the user when the planned dose and the prescribed dose disagree. PCT includes a comprehensive checklist of automated and manual checks that are documented when performed by the user. A PDF report is created and automatically uploaded into the TMS. Prior to and during PCT development, errors caught during plan checks and also patient delays were tracked in order to prioritize which checks should be automated. The most common and significant errors were determined. Results: Nineteen of 33 checklist items were automated with data extracted with the PCT. These include checks for prescription, reference point and machine scheduling errors which are three of the top six causes of patient delays related to physics and dosimetry. Since the clinical roll-out, no delays have been due to errors that are automatically flagged by the PCT. Development continues to automate the remaining checks. Conclusion: With PCT, 57% of the physics plan checklist has been partially or fully automated. Treatment delays have declined since release of the PCT for clinical use. By tracking delays and errors, we have been able to measure the effectiveness of automating checks and are using this information to prioritize future development.

2017-01-01

A study was conducted on 37 randomly selected broiler poultry farmers in Rwanda to characterize the production system using pre-tested semi-structured questionnaires. The data were processed in SPSS and presented as means, percentages and ranges in tables and text. All respondents kept Cobb breed and young stock was mainly (73 %) imported from abroad. The majority of respondents were males (68 %) and most farmers had attended only primary level of education (40.5 %). Most of the farms were in the peri-urban (48.6 %) and urban (37.8 %) areas and hired male youth (62.2 %) mainly aged 19-35 years. The majority of respondents (68 %) kept less than 500 birds per batch. Recordkeeping was well practiced (91.9 %) and (62.6 %) had permanent poultry houses and all farmers used deep litter system. Purchased feedstuffs were reportedly (92 %) mixed at farm level as the main feed resource. Maize bran was reported (97.06 %) the main, basal feedstuff. The mortality rates of chick and growers were 12.3 and 9.4 %, respectively. The slaughter age was reportedly 60 days with an average dressing percentage of 75.67 %. The main challenges reported were scarcity and unaffordability of quality feeds (59.5 %), lack of market access (45 %) and lack of credit (21 %). The farmers had various views on improving broiler production in Rwanda ranging from establishing feed processing industries 62.2 %, improving marketing facilities 35.1 %, increasing availability of day-old chick and access credit 27 %, to intensification of farmer training 16.2 %.

This research was aimed at the evaluation of the antimicrobial activity exerted by poultry protein hydrolyzates derived from industrial leftovers added to minced turkey meat, intended for the production of burgers for human consumption. Hydrolyzates were obtained through enzymatic hydrolysis from poultry bone and meat trimmings, as by-products from the poultry industry. Colony forming unit assays, under both laboratory and industrial conditions, were performed to assess microbial growth. Poultry protein hydrolyzates inhibited microbial growth occurring in semi-finished turkey meat during the normal retention period because of their water holding capacity resulting in a decreased water activity. Overall, the findings demonstrated that poultry protein hydrolyzates could decrease mesophilic, psychrophilic, and thermophilic bacterial growth for the entire product shelf-life. Bacterial growth inhibition obtained in minced turkey meat by addition of poultry protein hydrolyzates (1.5%), hygroscopic amino acids mixture (1.5%) or sodium chloride (1%) was similar. It is suggested that the use of hydrolyzates could allow the reduction of salt content in poultry meat based products leading to the production of low-sodium turkey food still maintaining acceptable sensory characteristics.

Objective To evaluate associations between poultry processing work and respiratory health among working Latino men and women in North Carolina. Methods Between May 2009 and November 2010, 402 poultry processing workers and 339 workers in a comparison population completed interviewer-administered questionnaires. Of these participants, 279 poultry processing workers and 222 workers in the comparison population also completed spirometry testing to provide measurements of forced expiratory volume in 1 second and forced vital capacity. Results Nine percent of poultry processing workers and 10% of workers in the comparison population reported current asthma. Relative to the comparison population, adjusted mean forced expiratory volume in 1 second and forced vital capacity were lower in the poultry processing population, particularly among men who reported sanitation job activities. Conclusions Despite the low prevalence of respiratory symptoms reported, poultry processing work may affect lung function. PMID:22237034

Campylobacteriosis is the most common cause of bacterial gastroenteritis worldwide. Consumption of poultry, especially chicken's meat is considered the most common route for human infection. The aim of this study was to determine if Campylobacter spp. might persist in the poultry plant environment before and after cleaning and disinfection procedures and the distribution and their genetic relatedness. During one month from a poultry plant were analyzed a total of 494 samples -defeathering machine, evisceration machine, floor, sink, conveyor belt, shackles and broiler meat- in order to isolate C. jejuni and C. coli. Results showed that C. jejuni and C. coli prevalence was 94.5% and 5.5% respectively. Different typing techniques as PFGE, MLST established seven C. jejuni genotypes. Whole genome MLST strongly suggest that highly clonal populations of C. jejuni can survive in adverse environmental conditions, even after cleaning and disinfection, and persist for longer periods than previous thought (at least 21 days) in the poultry plant environment. Even so, it might act as a source of contamination independently of the contamination level of the flock entering the slaughter line. Copyright © 2017 Elsevier Ltd. All rights reserved.

1994-12-31

The purpose of the study was an evaluation of the effect of ionizing radiation on detection of oxytetracycline residues in poultry meat. Oxytetracycline was chosen as a representative of tetracyclines which are often applied in poultry for therapeutical reasons. The experiment was conducted using both broiler meat treated by oxytetracycline and slurry of broiler meat containing appropriate concentration of this antibiotic. A traditional microbiological method for determination of antibiotics antimicrobial activity was used. A significant decrease of oxytetracycline concentration in meat slurry as a result of irradiation was noted. A dose of 1 kGy reduced concentration of tetracycline to ca 40% and a dose of 3 kGy reduced it to ca 3%. In ground poultry meat a dose of 1 kGy reduced this antibiotic concentration to 70%, a dose of 3 kGy reduced oxytetracycline concentration to 35% and a 5 kGy dose reduced it up to ca 18% of initial concentration. It can be concluded that irradiation of poultry meat with radurization doses can cause some difficulties in detection of tetracycline residues in meat using traditional microbiological methods of detection.

Exposure to infected poultry is a suspected cause of avian influenza (H5N1) virus infections in humans. We detected infectious droplets and aerosols during laboratory-simulated processing of asymptomatic chickens infected with human- (clades 1 and 2.2.1) and avian- (clades 1.1, 2.2, and 2.1) origin H5N1 viruses. We detected fewer airborne infectious particles in simulated processing of infected ducks. Influenza virus-naive chickens and ferrets exposed to the air space in which virus-infected chickens were processed became infected and died, suggesting that the slaughter of infected chickens is an efficient source of airborne virus that can infect birds and mammals. We did not detect consistent infections in ducks and ferrets exposed to the air space in which virus-infected ducks were processed. Our results support the hypothesis that airborne transmission of HPAI viruses can occur among poultry and from poultry to humans during home or live-poultry market slaughter of infected poultry.

The wide circulation of novel avian influenza viruses (AIVs) highlights the risk of pandemic influenza emergence in China. To investigate the prevalence and genetic diversity of AIVs in different ecological contexts, we surveyed AIVs in live poultry markets (LPMs), free-range poultry and the wetland habitats of wild birds in Zhejiang and Hubei provinces. Notably, LPMs contained the highest frequency of AIV infection, and the greatest number of subtypes (n = 9) and subtype co-infections (n = 14), as well as frequent reassortment, suggesting that they play an active role in fuelling AIV transmission. AIV-positive samples were also identified in wild birds in both provinces and free-range poultry in one sampling site close to a wetland region in Hubei. H9N2, H7N9 and H5N1 were the most commonly sampled subtypes in the LPMs from Zhejiang, whilst H5N6 and H9N2 were the dominant subtypes in the LPMs from Hubei. Phylogenetic analyses of the whole-genome sequences of 43 AIVs revealed that three reassortant H5 subtypes were circulating in LMPs in both geographical regions. Notably, the viruses sampled from the wetland regions and free-range poultry contained complex reassortants, for which the origins of some segments were unclear. Overall, our study highlights the extent of AIV genetic diversity in two highly populated parts of central and south-eastern China, particularly in LPMs, and emphasizes the need for continual surveillance.

The USDA Food Safety and Inspection Service determined populations of bacteria on poultry during processing at a slaughter plant in Puerto Rico in November and December 1987. The plant was selected because of its management's willingness to support important changes in equipment and processing procedures. The plant was representative of modern slaughter facilities. Eight-hundred samples were collected over 20 consecutive 8-hour days of operation from 5 sites in the processing plant. Results indicated that slaughter, dressing, and chilling practices significantly decreased the bacterial contamination on poultry carcasses, as determined by counts of aerobic bacteria, Enterobacteriaceae, and Escherichia coli. Salmonella was not enumerated; rather, it was determined to be present or absent by culturing almost the entire rinse. The prevalence of Salmonella in the study decreased during evisceration, then increased during immersion chilling.

Control of poultry red mites

The poultry red mite (PRM), Dermanyssus gallinae, is the most important ectoparasite in European egg production. The mites hide in cracks and crevices in the near vicinity of the resting places of the birds, coming out to feed mainly during the night. Under favourable conditions the population can...... grow rapidly, leading to serious problems. Large mite populations may cause anaemia or even death to the poultry, but also in lower numbers mites may be a nuisance to the birds causing decreased egg production and egg quality. Furthermore, they may have the potential of acting as reservoir......-pathogenic fungi and desiccant dust. The dust is diatomaceous earth (of natural origin), synthetic silica products or combinations of the two. The progress of the work with desiccant dusts will be reported.

Antimicrobial use in Chinese swine and broiler poultry production.

Science.gov (United States)

Krishnasamy, Vikram; Otte, Joachim; Silbergeld, Ellen

2015-01-01

Antimicrobial use for growth promotion in food animal production is now widespread. A major concern is the rise of antimicrobial resistance and the subsequent impact on human health. The antimicrobials of concern are used in concentrated animal feeding operations (CAFOs) which are responsible for almost all meat production including swine and poultry in the US. With global meat consumption rising, the CAFO model has been adopted elsewhere to meet this demand. One such country where this has occurred is China, and evidence suggests 70% of poultry production now occurs outside of traditional small farms. Moreover, China is now the largest aggregate consumer of meat products in the world. With this rapid rise in consumption, the Chinese production model has changed along with the use of antimicrobials in feeds. However, the specific antibiotic use in the Chinese food animal production sector is unclear. Additionally, we are aware of high quantities of antimicrobial use because of reports of high concentrations of antimicrobials in animal waste and surface waters surrounding animal feeding operations. In this report, we estimate the volume of antibiotics used for swine and poultry production as these are the two meat sources with the highest levels of production and consumption in China. We adopt a model developed by Mellon et al. in the US for estimating drug use in feed for poultry and swine production to estimate overall antimicrobial use as well as antimicrobial use by class. We calculate that 38.5 million kg [84.9 million lbs] were used in 2012 in China's production of swine and poultry. By antibiotic class, the highest weights are tetracyclines in swine and coccidiostats in poultry. The volume of antimicrobial use is alarming. Although there are limitations to these data, we hope our report will stimulate further analysis and a sense of urgency in assessing the consequences of such high levels of utilization in terms of antibiotic resistance in the food supply

Infectious diseases in poultry can spread quickly and lead to huge economic losses. In the past decade, on multiple continents, the accelerated spread of highly pathogenic avian Influenza A (H5N1) virus, often through informal trade networks, has led to the death and culling of hundreds of millions of poultry. Endemic poultry diseases like Newcastle disease and fowl typhoid can also be devastating in many parts of the world. Understanding trade networks in unregulated systems can inform policy decisions concerning disease prevention and containment. From June to December 2008 we conducted a cross-sectional survey of backyard farmers, market traders, and middlemen in 5/8 provinces in Kenya. We administered a standardized questionnaire to each type of actor using convenience, random, snowball, and systematic sampling. Questionnaires addressed frequency, volume, and geography of trade, as well as biosecurity practices. We created a network diagram identifying the most important locations for trade. Of 380 respondents, 51% were backyard farmers, 24% were middlemen and 25% were market traders. Half (50%) of backyard farmers said they raised poultry both for household consumption and for sale. Compared to market traders, middlemen bought their poultry from a greater number of villages (median 4.2 villages for middlemen vs. 1.9 for market traders). Traders were most likely to purchase poultry from backyard farmers. Of the backyard farmers who sold poultry, 51% [CI 40-63] reported selling poultry to market traders, and 54% [CI 44-63] sold to middlemen. Middlemen moved the largest volume of poultry on a weekly basis (median purchases: 187 birds/week [IQR 206]; median sales: 188 birds/week [IQR 412.5]). The highest numbers of birds were traded in Nairobi - Kenya's capital city. Nairobi was the most prominent trading node in the network (61 degrees of centrality). Many smaller sub-networks existed as a result of clustered local trade. Market traders were also integral to the

2010-02-01

Utilization of poultry litter as a precursor material to manufacture activated carbon for treating heavy metal-contaminated water is a value-added strategy for recycling the organic waste. Batch adsorption experiments were conducted to investigate kinetics, isotherms, and capacity of poultry litter-based activated carbon for removing heavy metal ions in water. It was revealed that poultry litter-based activated carbon possessed significantly higher adsorption affinity and capacity for heavy metals than commercial activated carbons derived from bituminous coal and coconut shell. Adsorption of metal ions onto poultry litter-based carbon was rapid and followed Sigmoidal Chapman patterns as a function of contact time. Adsorption isotherms could be described by different models such as Langmuir and Freundlich equations, depending on the metal species and the coexistence of other metal ions. Potentially 404 mmol of Cu2+, 945 mmol of Pb2+, 236 mmol of Zn2+, and 250-300 mmol of Cd2+ would be adsorbed per kg of poultry litter-derived activated carbon. Releases of nutrients and metal ions from litter-derived carbon did not pose secondary water contamination risks. The study suggests that poultry litter can be utilized as a precursor material for economically manufacturing granular activated carbon that is to be used in wastewater treatment for removing heavy metals.

An alternative for antibiotic se in poultry: probiotics

Directory of Open Access Journals (Sweden)

FW Edens

2003-05-01

Full Text Available Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in the intestinal tract, reduced bacterial contamination on processed broiler carcasses, enhanced nutrient absorption and performance, and ultimately decreased human health risk. The development of these factors generally can be ascribed to the ability of most probiotic products to balance and maintain the intestinal microflora in poultry species.

This research examined how perceptions of outbreaks of highly pathogenic avian influenza (HPAI) subtype H5N1 in poultry are related to urbanization. Via in-depth interviews with village leaders, household farmers, and large farm operators in modern, transitional, and traditional communes in the north of Vietnam, we explored behaviors, attitudes, cultural values, and traditions that might amplify or attenuate HPAI outbreaks. We also explored conceptualizations of urbanization and its impacts on animal husbandry and disease outbreaks. Qualitative theme analyses identified the key impacts, factors related to HPAI outbreaks, and disease prevention and management strategies. The analyses also highlighted how urbanization improves some aspects of life (e.g., food security, family wealth and health, more employment opportunities, and improved infrastructure), but simultaneously poses significant challenges for poultry farming and disease management. Awareness of qualitative aspects of HPAI risk perceptions and behaviors and how they vary with urbanization processes may help to improve the prevention and management of emerging infectious diseases.

Byrd, J A; Caldwell, D Y; Nisbet, D J

2017-07-01

Under normal conditions, fungi are ignored unless a disease/syndrome clinical signs are reported. The scientific communities are largely unaware of the roles fungi play in normal production parameters. Numerous preharvest interventions have demonstrated that beneficial bacteria can play a role in improving productions parameters; however, most researchers have ignored the impact that fungi may have on production. The goal of the present study was to record fungi recovered from commercial broiler and layer houses during production. Over 3,000 cecal samples were isolated using conventional culture methodology and over 890 samples were further characterized using an automated repetitive sequence-based PCR (rep-PCR) methodology. Eighty-eight different fungal and yeast species were identified, including Aspergillus spp., Penicillium spp., and Sporidiobolus spp, and 18 unknown genera were separated using rep-PCR. The results from the present study will provide a normal fungi background genera under commercial conditions and will be a stepping stone for investigating the impact of fungi on the gastrointestinal tract and on the health of poultry.

Improvement of production standards in a company leader in the poultry meat market: the competent authority’s role

Directory of Open Access Journals (Sweden)

Monica Gramenzi

2013-09-01

Full Text Available The object of this study was to evaluate, in a company that is leader in the production of poultry meat, the effects of the combined action between the official veterinary controls and the food business operator (FBO on corporate manufacturing standards. To this purpose, the corporate documentation have been examined (inspection reports and audits of official veterinary controls and data obtained by self-control procedures on a four-year period between 2008 and 2011. The results obtained showed that, despite the application of specific procedures by the FBO, the competent authority has observed a number of non-compliances, grouped into four main areas: cleaning and disinfection, maintenance in the plant, staff training, management of animal by-products. The immediate response of the FBO for the resolution of the non-compliances resulted in an overall significant improvement in hygiene and safety of products and processes, a gradually reduced number of non-compliance reports, a decrease of all microbiological parameters and the extension of products’ shelf life.

2010-06-01

The purpose of this study was to determine whether the methods used in compost operations of small and medium-sized poultry farms resulted in the production of an amendment free of foodborne pathogens. Nine compost heaps on five South Carolina poultry farms were surveyed at different stages of the composting process. Compost samples were analysed for coliforms and enriched for Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes. The waste materials and composting practices differed among the surveyed farms. On two farms, new materials were added to heaps that had previously completed the active composting phase. Five compost heaps did not reach an internal temperature of 55 degrees C, and c. 62% of all internal samples in the first composting phase contained moisture contents poultry wastes. This research provides information regarding the effectiveness of the composting practices and microbiological quality of poultry compost produced by small- and medium-sized farms. Ensuring the safety of compost that may be applied to soils should be an integral part of preharvest food safety programme.

zeolite dosages on the mesophilic AD of poultry manure inoculated with a non-acclimatised to ammonia inoculum (dairy manure) was investigated. Additionally, a comparative analysis was performed between the data extracted from this study and the results of a previous study which has been conducted under...... the same experimental conditions but with the use of ammonia acclimatised inoculum (swine manure). At 5 and 10 g zeolite L−1, the methane yield of poultry manure was 43.4% and 80.3% higher compared with the experimental set without zeolite addition. However, the ammonia non-acclimatised inoculum...... was not efficient in digesting poultry manure even in the presence of 10 g zeolite L−1, due to low methane production (only 39%) compared to the maximum theoretical yield. Finally, ammonia acclimatised inoculum and zeolite have demonstrated a possible “synergistic effect” which led to a more efficient AD of poultry...

With the increase in regulations regarding the use of antibiotic growth promoters and the rise in consumer demand for poultry products from 'Raised Without Antibiotics' or 'No Antibiotics Ever' flocks, the quest for alternative products or approaches has intensified in recent years. A great deal of research has focused on the development of antibiotic alternatives to maintain or improve poultry health and performance. This review describes the potential for the various alternatives available to increase animal productivity and help poultry perform to their genetic potential under existing commercial conditions. The classes of alternatives described include probiotics, prebiotics, synbiotics, organic acids, enzymes, phytogenics, antimicrobial peptides, hyperimmune egg antibodies, bacteriophages, clay, and metals. A brief description of the mechanism of action, efficacy, and advantages and disadvantages of their uses are also presented. Though the beneficial effects of many of the alternatives developed have been well demonstrated, the general consensus is that these products lack consistency and the results vary greatly from farm to farm. Furthermore, their mode of action needs to be better defined. Optimal combinations of various alternatives coupled with good management and husbandry practices will be the key to maximize performance and maintain animal productivity, while we move forward with the ultimate goal of reducing antibiotic use in the animal industry.

Campylobacter, a common poultry intestine commensal, is a well known cause of human gastric illnesses across the globe. Consumption of contaminated poultry meat is a major cause of Campylobacter related infections. In the present study, radiation sensitivity of indigenous strains of C. jejuni and C. coli isolated from poultry was evaluated. The decimal reduction dose (D 10 ) values of different Campylobacter isolates at 0-4 o C in saline and blood broth were in the range of 0.120-0.210 kGy and 0.170-0.234 kGy, respectively. D 10 values in chicken meat homogenate for Campylobacter were in the range of 0.110-0.190 kGy. Chicken meat samples were inoculated with C. jejuni and exposed to gamma radiation to study the effectiveness of radiation treatment in elimination of Campylobacter. Radiation treatment with a dose of 1 kGy could achieve complete elimination of 10 5 CFU of Campylobacter/g in poultry meat samples. No recovery of Campylobacter was observed, even after enrichment and selective plating in 1 kGy treated chicken meat samples stored at 4 o C up to 7 days. Present study shows that irradiation of poultry meat with 1 kGy can ensure safety of poultry meat. - Highlights: → Campylobacter isolates were sensitive to gamma radiation. → Low dose of 1 kGy is effective for 5-log reduction of Campylobacter in chicken meat. → No recovery of Campylobacter in radiation processed samples during storage. → First report on radiation sensitivity of Indian Campylobacter isolates.

Full Text Available The paper goal was to study consumer behaviour for poultry meat. In this purpose 100 individuals participated to a questionnaire based survey  in a supermarket of  Bucharest. Specific methods of marketing research in such a case assured the statistical processing of the respondents’ answers. The results pointed out an increased consumption of poultry meat,  a preference for fresh chicken meat which is daily bought  or 2-3 times a week in a varied amount ranging between 1-1.5 kg depending on consumer’s income for covering the family need. The main factors influencing consumer buying decision are the sensorial meat characteristics, meat quality, origin, price, prepaking grade. As a conclusion producers have to pay more attention to these aspects in their future strategy for producing and commercialising poultry meat.

Learning to improve path planning performance

International Nuclear Information System (INIS)

Chen, Pang C.

1995-04-01

In robotics, path planning refers to finding a short. collision-free path from an initial robot configuration to a desired configuratioin. It has to be fast to support real-time task-level robot programming. Unfortunately, current planning techniques are still too slow to be effective, as they often require several minutes, if not hours of computation. To remedy this situation, we present and analyze a learning algorithm that uses past experience to increase future performance. The algorithm relies on an existing path planner to provide solutions to difficult tasks. From these solutions, an evolving sparse network of useful robot configurations is learned to support faster planning. More generally, the algorithm provides a speedup-learning framework in which a slow but capable planner may be improved both cost-wise and capability-wise by a faster but less capable planner coupled with experience. The basic algorithm is suitable for stationary environments, and can be extended to accommodate changing environments with on-demand experience repair and object-attached experience abstraction. To analyze the algorithm, we characterize the situations in which the adaptive planner is useful, provide quantitative bounds to predict its behavior, and confirm our theoretical results with experiments in path planning of manipulators. Our algorithm and analysis are sufficiently, general that they may also be applied to other planning domains in which experience is useful

Cleaning and disinfection (C&D) of poultry houses is an essential aspect in farm hygiene management. Adequate performance of the different steps of a C&D protocol and the use of suitable products are key to prevent and control zoonoses and animal diseases. Hygiene monitoring on total aerobic flora through sampling with agar contact plates at different locations of the poultry house results in a hygienogram score that is used to evaluate the proper execution of C&D.This study analyzed the hygienogram scores of 19,739 poultry flocks in Flanders after C&D. Data relating to the C&D protocol, i.e., year, season, husbandry system, production type, cleaning product, sampler, active components of the disinfectant, disinfection time, disinfection temperature, and disinfection responsible, were collected.The average hygienogram score decreased significantly over time, suggesting a general improvement between 2007 and 2014. Differences in scores were found among the husbandry systems, with the barn/aviary system having a significantly better hygienogram score compared to the floor house, furnished cage, and battery. Significantly better scores also were found when a cleaning product was used in the C&D protocol. Disinfection with a peracetic acid and hydrogen peroxide combination or formaldehyde gave the best scores. In addition, C&D protocols using ≥2 different disinfectants showed improved results compared to the use of one single disinfectant. Finally, disinfection applied by a specialist contractor resulted in a better score compared to disinfection by the farmer.In conclusion, analysis of the hygienogram scores and related data allowed identifying several factors, resulting in an improvement, which may reduce the total bacterial load in poultry stables and, consequently, the number of zoonotic and pathogenic micro-organisms. © 2017 Poultry Science Association Inc.

Bacteriophage therapy to combat bacterial infections in poultry.

Infections in poultry are an economic and health problem in Europe and worldwide. The most common infections are associated with salmonellosis, colibacillosis, campylobacteriosis, and others. The prevalence of Campylobacter-positive poultry flocks in European countries varies from 18% to 90%. In the United States, the prevalence of infected flocks is nearly 90%. A similar percentage of infection has been noted for salmonellosis (about 75-90%) and E. coli (90-95%). The occurence of Clostridium perfringens is a major problem for the poultry industry, with some estimates suggesting colonization of as many as 95% of chickens, resulting in clinical or subclinical infections. In the US, annual economic losses due to Salmonella infections run from $1.188 billion to over $11.588 billion, based on an estimated 1.92 million cases. Similar costs are observed in the case of other types of infections. In 2005 economic losses in the the poultry industry due to mortalities reached 1,000,000 USD.Infections caused by these pathogens, often through poultry products, are also a serious public health issue.The progressive increase in the number of multi-drug resistant bacteria and the complete ban on the use of antibiotics in livestock feed in the EU, as well as the partial ban in the US, have led to the growth of research on the use of bacteriophages to combat bacterial infections in humans and animals.The high success rate and safety of phage therapy in comparison with antibiotics are partly due to their specificity for selected bacteria and the ability to infect only one species, serotype or strain. This mechanism does not cause the destruction of commensal bacterial flora. Phages are currently being used with success in humans and animals in targeted therapies for slow-healing infections. They have also found application in the US in eliminating pathogens from the surface of foods of animal and plant origin. At a time of growing antibiotic resistance in bacteria and the resulting

A study was conducted to evaluate the occurrence of ochratoxin A (OTA) in complete poultry feeds (n=80) and poultry feed ingredients (n=286) from Pakistan. All samples were first analyzed by indirect enzyme linked immunosorbent assay (ELISA), samples with OTA concentrations above the European Union maximum regulatory limit (MRL, 100 μg/kg) were further confirmed by HPLC-FLD. Contamination frequency and mean OTA levels were 31% and 51 μg/kg in feed ingredients, and the corresponding values for complete feeds were 38% and 75 μg/kg. Ten samples of complete poultry feed and 19 samples of feed ingredients contained OTA at levels higher than the MRL. The results of the present study indicate that there is a strong need for a more intense monitoring programs for OTA in poultry feed.

PRODUCTION OF POULTRY MEAT AND EGGS IN THE REPUBLIC OF CROATIA AND IN THE EUROPEAN UNION

Directory of Open Access Journals (Sweden)

Davor Bošnjaković

2017-01-01

Full Text Available Poultry meat and eggs are a significant source of nutrients in the human diet. Poultry products are widely consumed because they are nutritionally valuable, there are no religious restrictions on consumption, it is relatively easy to prepare diverse meals based on poultry, and the price of such products is relatively low. The aim of this research was to investigate the development of poultry production in the Republic of Croatia in the period 2010-2014, comprising the period of two years after Croatia joined the EU. The paper also compares data of poultry production in Croatia and in the EU. Over the period in question, total meat production in Croatia was reduced by 23%, meat import was increased by 45%, poultry meat export was increased by 46%, and production of eggs decreased by 20%. At the same time, in the EU countries poultry production was increased by 8.8% on average, export was increased by 10%, and import was reduced by 3.7%, while the egg production stagnated. In 2014, consumption of poultry meat in Croatia was 18.3 kg per capita, and in the EU 26.8 kg per capita. Self-sufficiency in the poultry production over the analyzed period was not satisfactory, therefore in the coming years, Croatia will have to develop quickly this important branch of livestock breeding. In addition to conventional production, faster development refers to production of organic and functional poultry products.

Garbage Management: An Important Risk Factor for HPAI-Virus Infection in Commercial Poultry Flocks.

Science.gov (United States)

Walz, Emily; Linskens, Eric; Umber, Jamie; Culhane, Marie Rene; Halvorson, David; Contadini, Francesca; Cardona, Carol

2018-01-01

Garbage management represents a potential pathway of HPAI-virus infection for commercial poultry operations as multiple poultry premises may share a common trash collection service provider, trash collection site (e.g., shared dumpster for multiple premises) or disposal site (e.g., landfill). The types of potentially infectious or contaminated material disposed of in the garbage has not been previously described but is suspected to vary by poultry industry sector. A survey of representatives from the broiler, turkey, and layer sectors in the United States revealed that many potentially contaminated or infectious items are routinely disposed of in the trash on commercial poultry premises. On-farm garbage management practices, along with trash hauling and disposal practices are thus key components that must be considered to evaluate the risk of commercial poultry becoming infected with HPAI virus.

Is Exposure to Poultry Harmful to Child Nutrition? An Observational Analysis for Rural Ethiopia.

Science.gov (United States)

Headey, Derek; Hirvonen, Kalle

2016-01-01

Although strategic thinking on water, sanitation and hygiene (WASH) has prioritized reducing exposure to human feces in order to limit diarrheal infections, recent research suggests that elevated exposure to livestock-particularly poultry and poultry feces-may be an important risk factor for diarrhea, environmental enteric disorder (EED) and respiratory infections, all of which may seriously retard linear growth in young children. Yet a very different literature on nutrition-sensitive agriculture suggests that livestock ownership is highly beneficial for child growth outcomes through its importance for increasing consumption of nutrient-rich animal sourced foods, such as eggs. Together, these two literatures suggest that the net nutritional benefit of poultry ownership is particularly ambiguous and potentially mediated by whether or not children are highly exposed to poultry. We test this novel hypothesis using a large agricultural survey of rural Ethiopian households that includes measures of child height-for-age Z-scores (HAZ), ownership of poultry and other types of livestock, and an indicator of whether livestock are kept within the main household dwelling overnight. We used least squares regression analysis to estimate unadjusted and adjusted models that control for a wide range of potentially confounding factors. We find that while poultry ownership is positively associated with child HAZ [β = 0.291, s.e. = 0.094], the practice of corralling poultry in the household dwelling overnight is negatively associated with HAZ [β = -0.250, s.e. = 0.118]. Moreover, we find no negative associations between HAZ and corralling other livestock species indoors. These results suggest that while poultry ownership can be beneficial to child growth, overly close exposure to poultry poses a concurrent risk factor for undernutrition, most likely because of increased risk of infection.

Improved operational performance at Point Beach Nuclear Plant is based on a focused business plan. Quantitative goals that compare past performance with the performance of potential competitors are the basis of the business plan. This establishes goals for the nuclear power business unit which support corporate goals. Strategies and objectives are then developed to meet the established goals. To continue support for these strategies and objectives, individual performance plans are developed for all management personnel. These performance management plans identify individual contributor actions to support the goals, and also provide periodic feedback for changes to better prioritize individual actions. Performance criteria are also established to measure progress toward achieving the goals. The author also has a program to provide incentives for improved performance based upon success of the organization in achieving established goals

Analysis of hyperspectral fluorescence images for poultry skin tumor inspection

Science.gov (United States)

Kong, Seong G.; Chen, Yud-Ren; Kim, Intaek; Kim, Moon S.

2004-02-01

We present a hyperspectral fluorescence imaging system with a fuzzy inference scheme for detecting skin tumors on poultry carcasses. Hyperspectral images reveal spatial and spectral information useful for finding pathological lesions or contaminants on agricultural products. Skin tumors are not obvious because the visual signature appears as a shape distortion rather than a discoloration. Fluorescence imaging allows the visualization of poultry skin tumors more easily than reflectance. The hyperspectral image samples obtained for this poultry tumor inspection contain 65 spectral bands of fluorescence in the visible region of the spectrum at wavelengths ranging from 425 to 711 nm. The large amount of hyperspectral image data is compressed by use of a discrete wavelet transform in the spatial domain. Principal-component analysis provides an effective compressed representation of the spectral signal of each pixel in the spectral domain. A small number of significant features are extracted from two major spectral peaks of relative fluorescence intensity that have been identified as meaningful spectral bands for detecting tumors. A fuzzy inference scheme that uses a small number of fuzzy rules and Gaussian membership functions successfully detects skin tumors on poultry carcasses. Spatial-filtering techniques are used to significantly reduce false positives.

1998-01-01

The purpose of this work was to determine the mycoflora and mycotoxins natural incidence in poultry feeds from 2 factories in Río Cuarto, Córdoba. One hundred and thirty samples were taken from May/1996 to May/1997. The most dominant species isolated of poultry feed samples belonged to the genera Aspergillus spp 85% and Fusarium spp 70%. From Aspergillus genus eleven species were identified and A. flavus was the most frequent. Nine species were identified from the Fusarium genus and the predominant was F. moniliforme. Penicillium ranked third in the number of isolated cases. From this genus twelve species were collected of which P. brevicompactum (15%), P. restrictum (14%) and P. purpurogenum (12%) were the most common. The most significant mycotoxin from poultry feeds was aflatoxin B1 (AFB1) found in 48% of the samples, with levels ranging from 10 to 123 ng/g. For zearalenone (ZEA) the levels were 327 to 5, 850 ng/g and DON was not detected from the samples. Due to the fact that in Argentina there is little information about this topic, these data on poultry feeds in our region would be of worldwide interest.

Unhygienic poultry feedstuffs can lead to nutrient losses and detrimental effect on poultry production and public health. In the present study, mycobiota and colony-forming units per gram in ingredients and finish poultry feed was evaluated with special reference to potentially mycotoxigenic fungi. Eighty five samples of corn, soybean meal and poultry finished feed were collected from nine poultry feed factories located in three provinces i.e. Tehran, Alborz and Qom in Iran from October 2014 to January 2015. Samples were cultured on Sabouraud dextrose agar (SDA), Aspergillus flavus and parasiticus agar (AFPA) and dichloran rosebengal chloramphenicol agar (DRBC) and incubated at 28 °C for 7-10 days. Purified fungal colonies were identified by a combination of macro- and microscopic morphological criteria. For determining the rate of fungal contamination, samples were cultured on SDA and colony forming units (CFUs) were calculated. A total of 384 fungal isolates belonging to 7 genera of filamentous fungi and yeasts were obtained from corn (124 isolates), soybean meal (92 isolates), and feed before (72 isolates), and after pelleting (96 isolates). The most prominent fungal isolate in corn, soybean meal and feed before pelleting (feed as mash form) was Fusarium but in feed after pelleting was Aspergillus. Among 5 Aspergillus species isolated, potentially aflatoxigenic A. flavus isolates was predominant in corn (46.6%), soybean meal (72.7%) and poultry finished feed (75%). CFUs results indicated that 9/22 corn samples (40.9%), none of 22 soybean meal samples, 19/41 finished feed (46.3%) were contaminated higher than the standard limit. Our results indicated that corn, soybean meal and finished feed of poultry feed mill are contaminated with various fungal genera by different levels sometimes higher that the standard limits. Contamination with potentially mycotoxigenic fungi especially Aspergillus species may be considered as a human public health hazard.

The goal of this work is to evaluate the effectiveness of Plan‐Checker Tool (PCT) which was created to improve first‐time plan quality, reduce patient delays, increase the efficiency of our electronic workflow, and standardize and automate the physics plan review in the treatment planning system (TPS). PCT uses an application programming interface to check and compare data from the TPS and treatment management system (TMS). PCT includes a comprehensive checklist of automated and manual checks that are documented when performed by the user as part of a plan readiness check for treatment. Prior to and during PCT development, errors identified during the physics review and causes of patient treatment start delays were tracked to prioritize which checks should be automated. Nineteen of 33 checklist items were automated, with data extracted with PCT. There was a 60% reduction in the number of patient delays in the six months after PCT release. PCT was successfully implemented for use on all external beam treatment plans in our clinic. While the number of errors found during the physics check did not decrease, automation of checks increased visibility of errors during the physics check, which led to decreased patient delays. The methods used here can be applied to any TMS and TPS that allows queries of the database. PACS number(s): 87.55.‐x, 87.55.N‐, 87.55.Qr, 87.55.tm, 89.20.Bb PMID:27929478

Slaughtering sick poultry is a risk factor for human infection with highly pathogenic avian influenza and is a common practice in Bangladesh. This paper describes human exposures to poultry during slaughtering process and the customs and rituals influencing these practices in two Bangladeshi rural communities. In 2009, we conducted 30 observations to observe slaughtering practices and 110 in-depth and short interviews and 36 group discussions to explore reasons behind those practices. The villagers reported slaughtering 103 poultry, including 20 sick poultry during 2 months. During different stages of slaughtering, humans, the environment, healthy poultry, and other animals were exposed to poultry blood and body parts. Women performed most of the slaughtering tasks, including evisceration. Defeathering required the most time and involved several persons. During festivals, ceremonies, and rituals, many people gathered and participated in the slaughtering of poultry. Exposure to poultry slaughtering created numerous opportunities for potential avian influenza transmission. Strategies that can be further tested to determine if they reduce the risk of transmission include skinning the carcasses of sick poultry, using hot water for defeathering and cleaning, using a bucket to contain slaughtering blood and carcass, burying the offal and encouraging handwashing.

Potential of fructooligosaccharide prebiotics in alternative and nonconventional poultry production systems.

Science.gov (United States)

Ricke, S C

2015-06-01

Fructooligosaccharide and inulin prebiotics are carbohydrate-based polymers derived from natural sources that can be utilized by certain gastrointestinal tract bacteria but not by the host animal. They are attractive as feed additives for nonconventional poultry production systems because they select for beneficial microorganisms that are thought to promote nutritional benefits to the bird and potentially limit foodborne pathogen establishment. There have been numerous studies conducted with prebiotic supplements to assess their impact in humans, animals, and conventionally raised poultry but only limited research has been conducted with birds grown under nonconventional production conditions. Much remains unknown about the specific mechanism(s) associated with their impact on the host as well as the gastrointestinal tract microflora. Utilization of several recently developed approaches such as microbiome and metabolomic analyses should offer more insight on how dietary prebiotic additives influence the development of the gastrointestinal tract microbiota and these subsequent changes correspond with alterations in a bird's physiology as it matures. As more detailed and precise studies are done with nonconventional poultry, it is likely that structurally distinct prebiotics will influence not only the gastrointestinal tract microbiota differently, but potentially interact directly and/or indirectly with the bird host in distinguishable patterns as well. These functions will be important to delineate if further applications are to be developed for specific prebiotics in nonconventional poultry production systems. © 2015 Poultry Science Association Inc.

Full Text Available A prevalence study was carried to isolate Salmonella typhimurium from blood (n= 50 and gut samples (n=100 of poultry in Kathmandu valley during early 2016. Salmonella typhimurium bacteria isolated in the selective media were biochemically confirmed based on Bergey’s Manual. Two sets of oligonucleotide primers-the genus specific 16S rRNA and the organism specific invA were employed for molecular level confirmation by the Polymerase Chain Reaction (PCR assay. The amplified fragments in 1% agarose gel observed at 406bp and 285bp, respectively confirmed the isolates to be Salmonella typhimurium. Of 150 samples tested, Salmonella typhimurium were isolated from 49 samples, among which nine were from blood (18% and forty from the gut (40%. The present result indicated an alarmingly high level of Salmonella typhimurium, which can result inzoonotic infection in humans owing to increased contact with poultry and consumption of poultry products in the Kathmandu valley.

When daily planning improves employee performance: The importance of planning type, engagement, and interruptions.

Parke, Michael R; Weinhardt, Justin M; Brodsky, Andrew; Tangirala, Subrahmaniam; DeVoe, Sanford E

2018-03-01

Does planning for a particular workday help employees perform better than on other days they fail to plan? We investigate this question by identifying 2 distinct types of daily work planning to explain why and when planning improves employees' daily performance. The first type is time management planning (TMP)-creating task lists, prioritizing tasks, and determining how and when to perform them. We propose that TMP enhances employees' performance by increasing their work engagement, but that these positive effects are weakened when employees face many interruptions in their day. The second type is contingent planning (CP) in which employees anticipate possible interruptions in their work and plan for them. We propose that CP helps employees stay engaged and perform well despite frequent interruptions. We investigate these hypotheses using a 2-week experience-sampling study. Our findings indicate that TMP's positive effects are conditioned upon the amount of interruptions, but CP has positive effects that are not influenced by the level of interruptions. Through this study, we help inform workers of the different planning methods they can use to increase their daily motivation and performance in dynamic work environments.

Biocrude oils from the fast pyrolysis of poultry litter and hardwood

International Nuclear Information System (INIS)

Agblevor, F.A.; Beis, S.; Kim, S.S.; Tarrant, R.; Mante, N.O.

2010-01-01

The safe and economical disposal of poultry litter is becoming a major problem for the USA poultry industry. Current disposal methods such as land application and feeding to cattle are now under pressure because of pollution of water resources due to leaching, runoffs and concern for mad cow disease contamination of the food chain. Incineration or combustion is potentially applicable to large scale operations, but for small scale growers and EPA non-attainment areas, this is not a suitable option because of the high cost of operation. Thus, there is a need for developing appropriate technologies to dispose poultry litter. Poultry litters from broiler chicken and turkey houses, as well as bedding material were converted into biocrude oil in a fast pyrolysis fluidized bed reactor. The biocrude oil yields were relatively low ranging from 36 wt% to 50 wt% depending on the age and bedding material content of the litter. The bedding material (which was mostly hardwood shavings) biocrude oil yield was 63 wt%. The higher heating value (HHV) of the poultry litter biocrude oils ranged from 26 MJ/kg to 29 MJ/kg while that of the bedding material was 24 MJ/kg. The oils had relatively high nitrogen content ranging from 4 wt% to 8 wt%, very low sulfur (<1 wt%) content and high viscosity. The viscosities of the oils appeared to be a function of both the source of litter and the pyrolysis temperature. The biochar yield ranged from 27 wt% to 40 wt% depending on the source, age and composition of the poultry litter. The biochar ash content ranged from 24 wt% to 54 wt% and was very rich in inorganic components such as potassium and phosphorous.

Harmse, Johannes L.; Engelbrecht, Jacobus C.; Bekker, Johan L.

2016-01-01

The poultry abattoir industry continues to grow and contribute significantly to the gross domestic product in many countries. The industry expects working shifts of eight to eleven hours, during which workers are exposed to occupational hazards which include physical hazards ranging from noise, vibration, exposure to cold and ergonomic stress from manual, repetitive tasks that require force. A PubMed, Medline and Science Direct online database search, using specific keywords was conducted and the results confirmed that physical and ergonomic hazards impact on abattoir processing workers health, with harm not only to workers’ health but also as an economic burden due to the loss of their livelihoods and the need for treatment and compensation in the industry. This review endeavours to highlight the contribution poultry processing plays in the development of physical agents and ergonomic stress related occupational diseases in poultry abattoir processing workers. The impact includes noise-induced hearing loss, increased blood pressure, menstrual and work related upper limb disorders. These are summarised as a quick reference guide for poultry abattoir owners, abattoir workers, poultry associations, occupational hygienists and medical practitioners to assist in the safer management of occupational health in poultry abattoirs.

2016-01-01

Effective methods to reduce work-related injuries and illnesses in animal production agriculture are sorely needed. One approach that may be helpful for agriculture producers is the adoption of occupational health and safety management systems. In this replication study, the authors compared the injury rates on 32 poultry growing operations with the level of occupational health and safety management system programming at each farm. Overall correlations between injury rates and programming level were determined, as were correlations between individual management system subcomponents to ascertain which parts might be the most useful for poultry producers. It was found that, in general, higher levels of occupational health and safety management system programming were associated with lower rates of workplace injuries and illnesses, and that Management Leadership was the system subcomponent with the strongest correlation. The strength and significance of the observed associations were greater on poultry farms with more complete management system assessments. These findings are similar to those from a previous study of the dairy production industry, suggesting that occupational health and safety management systems may hold promise as a comprehensive way for producers to improve occupational health and safety performance. Further research is needed to determine the effectiveness of such systems to reduce farm work injuries and illnesses. These results are timely given the increasing focus on occupational safety and health management systems.

Effects of Dietary Vitamin E on Fertility Functions in Poultry Species

2015-04-01

Full Text Available Vitamin E is found in high quantities in vegetable oils. Although vitamin E has multiple functions in humans and animals, its key function is protecting cells from oxidative damage. Since its discovery, several studies have demonstrated that vitamin E deficiency causes impaired fertility in humans and lab animals. However, the effects of vitamin E deficiency or of its supplementation on the fertility of farm animals, particularly on poultry, are less well studied. Therefore, a comprehensive review of the effects of dietary vitamin E on the fertility of poultry species is needed in order to understand the beneficial role of vitamin E in the maintenance of sperm and egg qualities. Based on the observations reviewed here, we found that a moderate amount of vitamin E in poultry diet significantly protects semen/sperm qualities in male birds and egg qualities in female birds via decreasing the lipid peroxidation in semen/sperms and eggs. This review provides an overall understanding of the effects of dietary vitamin E on fertility functions in poultry species.

Phosphorus (P) losses from pastures fertilized with poultry litter contribute to the degradation of surface water quality in the United States. Dietary modification and manure amendments may reduce potential P runoff losses from pastures. In the current study, broilers were fed a normal diet, phytase diet, high available phosphorus (HAP) corn diet, or HAP corn + phytase diet. Litter treatments were untreated control and alum added at 10% by weight between flocks. Phytase and HAP corn diets reduced litter dissolved P content in poultry litter by 10 and 35%, respectively, compared with the normal diet (789 mg P kg(-1)). Alum treatment of poultry litter reduced the amount of dissolved P by 47%, while a 74% reduction was noted after alum treatment of litter from the HAP corn + phytase diet. The P concentrations in runoff water were highest from plots receiving poultry litter from the normal diet, whereas plots receiving poultry litter from phytase and HAP corn diets had reduced P concentrations. The addition of alum to the various poultry litters reduced P runoff by 52 to 69%; the greatest reduction occurred when alum was used in conjunction with HAP corn and phytase. This study demonstrates the potential added benefits of using dietary modification in conjunction with manure amendments in poultry operations. Integrators and producers should consider the use of phytase, HAP corn, and alum to reduce potential P losses associated with poultry litter application to pastures.

Information on the proximate composition and sometimes the toxicology of novel feedstuffs has been used routinely in determining the suitability of feedstuffs in poultry feeding, especially during animal feeding trials. Limited information however exists on the biophysical characteristics of such novel feedstuffs. The Bulk Density (BD), Water-holding Capacity (WHC) and Specific Gravity (SG) of three novel feedstuffs {Leaf Meal (LEM), Rumen Digesta (RD) and Poultry Dung (PD)}, were evaluated. Available published and unpublished results on the proximate compositions of the materials were related to the physical characteristics results. LEM had significantly (p > 0.05) lower BD and SG than RD and PD while RD recorded the highest WHC value although the value was similar (p > 0.05) to that of LEM. Particle Size (PS) effects showed that BD of RD and PD were lower at the > or = 1.00 mm PS than at the unmodified and or = 1.00 mm PS levels, respectively. This is evidence that grinding increased the surface area of the LEM, thus improving the ability of its Non-starch Polysaccharides (NSP) to bind water. Information on the feed physical characteristics could be used together with proximate and toxicological information to determine the nutritional and intake potentials of a novel feedstuff even before a feeding trial.

Three biochars were prepared by intermediate pyrolysis from poultry litter at different temperatures (400, 500, and 600 °C with decreasing residence times) and compared with biochars from corn stalk prepared under the same pyrolysis conditions. The phytotoxicity of these biochars was estimated by means of seed germination tests on cress (Lepidium sativum L.) conducted in water suspensions (at 2, 5, and 40 g/L) and on biochars wetted according to their water-holding capacity. Whereas the seeds germinated after 72 h in water suspensions with corn stalk biochar were similar to the control (water only), significant inhibition was observed with poultry litter biochars. In comparison to corn stalk, poultry litter generated biochars with higher contents of ash, ammonium, nitrogen, and volatile fatty acids (VFAs) and a similar concentration of polycyclic aromatic hydrocarbons (PAHs). Results from analytical pyrolysis (Py-GC-MS) indicated that nitrogen-containing organic compounds (NCCs) and aliphatic components were distinctive constituents of the thermally labile fraction of poultry litter biochar. The inhibition of germination due to poultry litter biochar produced at 400 °C (PL400) was suppressed after solvent extraction or treatment with active sludge. A novel method based on solid-phase microextraction (SPME) enabled the identification of mobile organic compounds in PL400 capable of being released in air and water, including VFAs and NCCs. The higher phytotoxicity of poultry litter than corn biochars was tentatively attributed to hydrophilic biodegradable substances derived from lipids or proteins removable by water leaching or microbial treatments.

Poultry and poultry products are major contributors of zoonotic pathogens. Limited data are available on Enterobacter spp. as a potent zoonotic pathogen in poultry. The present study is a first endeavor on the emergence of multidrug-resistant zoonotic Enterobacter spp. and its prevalence arising from poultry in Bangladesh. Cloacal swabs from poultry samples of five different farms at Savar, Dhaka, Bangladesh were collected and from 106 isolates, 18 presumptive Enterobacter spp. were obtained. Antibiogram using 19 used antibiotics belonging to 15 major groups revealed that all of the 18 isolates were completely resistant to penicillin and rifampicin, but differed in their drug resistance pattern against ampicillin (94.4%), clindamycin (94.4%), erythromycin (94.4%), vancomycin (88.9%), sulfonamides (72.2%), imipenem (66.6%), streptomycin (55.6%), nitrofurantoin (33.3%), doxycycline (33.3%), tetracyclines (33.3%), cefepime (11.1%), and gentamicin (5.6%). All Enterobacter spp. were found to be plasmid free, implying that multidrug-resistant properties are chromosomal borne. The vanA and sulI were detected by polymerase chain reaction assay in 17 and 13 isolates, respectively. Amplified ribosomal DNA restriction analysis and randomly amplified polymorphic DNA distributed the 18 multidrug-resistant Enterobacter spp. into three genotypes. Phylogenetic analysis of the representatives of the three genotypes using partial 16S rRNA gene sequence (approximately 900 bp) showed that the genotypically diverse groups belonged to Enterobacter hormaechei, E. cloacae, and E. cancerogenus, respectively. The clinical significance of the close relative Enterobacter spp. is indicative of their zoonotic potential. Therefore, urgent intervention is required to limit the emergence and spread of these bacteria in poultry feed as well as prudent use of antibiotics among poultry farmers in Bangladesh.

Preliminary economic analysis of poultry litter gasification option with a simple transportation model.

Sheth, Atul C; English, Jennifer

2005-04-01

Several environmental issues are related to the disposal of poultry litter. In an effort to provide a more environmentally friendly alternative than landfill disposal or spreading as a soil amendment, work has been carried out previously at the University of Tennessee Space Institute (UTSI). This past UTSI work was concentrated on developing a catalytic steam gasification concept to produce energy from poultry litter. In the past UTSI studies, preliminary design and economics for a stationary, centralized gasification plant capable of processing approximately 100 ton/day of poultry litter were developed. However, in this preliminary design the economic impact of transporting litter to a centralized gasification plant location was not addressed. To determine the preliminary impact of transporting the poultry litter on the overall economics of this energy conversion plant design, a simple transportation model was developed. This model was used in conjunction with the earlier plant design prepared at UTSI to determine the economic feasibility of a centralized, stationary poultry litter gasification plant. To do so, major variables such as traveling distance, plant feed rate (or capacity), fluctuations in the sales price of the product gas (that means value of the energy), population density of poultry farms, impact of tipping fees, and cost of litter were varied. The study showed that for plant with a capacity of 1000 ton/day to be able to withstand several changes in economic conditions and sustain itself, the poultry farm density would need to be approximately 0.3 houses/mi2. Smaller plants would need either a higher energy price or some kind of subsidy to be economically feasible.

Alter, Thomas; Weber, Rita Margarete; Hamedy, Ahmad; Glünder, Gerhard

2011-01-10

Nineteen flocks of four poultry species were monitored at a veterinary field station to investigate the distribution and spread of Campylobacter genotypes between sequential and adjacent flocks. Caecal and liver samples were obtained at frequent intervals from birds of all flocks and examined for Campylobacter. Amplified fragment length polymorphism (AFLP) analysis was performed to genotype Campylobacter isolates. Of the 1643 caecal and liver samples investigated, 452 (27.5%) caecal samples and 11 (0.7%) liver samples contained Campylobacter. Of the caecal isolates 76.3% were identified as Campylobacter jejuni and 23.7% were identified as Campylobacter coli. Poultry flocks were largely colonized by more than one AFLP type and an intense exchange of Campylobacter genotypes between different poultry flocks occurred. These findings indicate that multiple genotypes can constitute the Campylobacter population within single poultry flocks, hinting to different sources of exposure and/or genetic drifts within the Campylobacter population. Nevertheless, in most flocks single Campylobacter genotypes predominated. Some strains superseded others resulting in colonization by successive Campylobacter genotypes during the observation period. In conclusion, the data demonstrate that the large genetic diversity of Campylobacter must be considered in epidemiological evaluations and microbial risk assessments of Campylobacter in poultry.

2017-08-01

The objective of this study was to evaluate the effect of heat treatment on poultry litter with different levels of reutilisation for potential generation of biogas in experimental biodigesters. Chicken litter used was obtained from two small-scale poultry houses where 14 birds m -2 were housed for a period of 42 days per cycle. Litter from aviary 1 received no heat treatment while each batch of litter produced from aviary 2 underwent a fermentation process. For each batch taken, two biodigesters were set for each aviary, with hydraulic retention time of 35 days. The efficiency of the biodigestion process was evaluated by biogas production in relation to total solids (TS) added, as well as the potential for power generation. Quantified volumes ranged from 8.9 to 41.1 L of biogas for aviary 1, and 6.7 to 33.9 L of biogas for aviary 2, with the sixth bed reused from both aviaries registering the largest biogas potential. Average potential biogas in m 3  kg -1 of TS added were 0.022 to 0.034 for aviary 1 and 0.015 to 0.022 for aviary 2. Energy values ​​of biogas produced were calculated based on calorific value and ranged from 0.06 to 0.33 kWh for chicken litter without fermentation and from 0.05 to 0.27 kWh for chicken litter with fermentation. It was concluded that the re-use of poultry litter resulted in an increase in biogas production, and the use of fermentation in the microbiological treatment of poultry litter seems to have negatively influenced production of biogas.

Full Text Available Backyard poultry farms in Trinidad and Tobago (T&T play a vital role in providing food and income for rural communities. There is currently no information on the presence and circulation of pathogens in backyard poultry farms in T&T, and little is known in relation to the potential risks of spread of these pathogens to the commercial poultry sector. In order to address this, serum samples were collected from 41 chickens on five backyard farms taken from selected locations in Trinidad. Samples were tested for antibodies to seven priority pathogens of poultry by enzyme-linked immunosorbent assay (ELISA. Antibodies were detected in 65% (CI 95%: 50–78% of the sampled birds for Infectious bronchitis virus (IBV, 67.5% (CI 95%: 52–80% for Infectious bursal disease virus (IBDV, 10% (CI 95%: 4–23% for Newcastle disease virus (NDV, 0% (CI 95%: 0–0% for Avian influenza virus (AIV, 0% (CI 95%: 0–0% for West Nile virus (WNV, 31.7% (CI 95%: 20–47% for Mycoplasm gallisepticum/synoviae and 0% (CI 95%: 0–0% for Salmonella enterica serotype Enteritidis. These results reveal the presence and circulation of important pathogens of poultry in selected backyard farms in Trinidad. The results provide important information which should be taken into consideration when assessing the risks of pathogen transmission between commercial and backyard poultry farms, as well as between poultry and wild birds.

The use of antimicrobials as growth-promoting factors (AGP in sub-therapeutic doses for long periods is particularly favorable to select antimicrobial-resistant microorganisms. In the last years, global concern about development of antimicrobial resistance and transference of resistance genes from animal to human strains has been arising. Removal of AGP from animal diets involves a tremendous pressure on the livestock and poultry farmers, one of the main consequences being a substantial increase in the incidence of infectious diseases with the related increase in the use of antibiotics for therapy and, concomitantly, economic cost. Therefore, alternatives to AGP are urgently needed. The challenge is to implement new alternatives without affecting the production performances of livestock and also avoiding the increase of antimicrobial resistant microorganisms. Plant extracts and purified derived substances are showing promising results for food animal production, either from their efficacy as well as from an economical point of view. Tannins are plant derived compounds that are being successfully used as additives in feed poultry to control diseases and to improve animal performance. Successful use of any of these extracts as feed additive must ensure a product of consistent quality in enough quantities to fulfill the actual requirements of the poultry industry. Chestnut (hydrolizable and Quebracho (condennsed tannins are probably the most readily available commercial products that are covering those needs. The present report intends to analyze the available data supporting their use.

Members of the Poultry Industry Association and the Egg Producers Federation of New Zealand (n=420) were sent a questionnaire asking them to describe the type and frequency of on- and off-enterprise movements relating to feed, live birds and hatching eggs, table eggs and poultry product, and manure and waste litter. Social network analyses were used to describe patterns of contact among poultry enterprises and their associates for these four movement types. The response rate to the survey was 58% (244 out of 420). Network structures for enterprise-to-enterprise movements of feed, live birds and hatching eggs, and table egg and poultry product were characterised by 'hub and spoke' type structures with small-world characteristics. Small worlds were created by network hubs (e.g. feed suppliers and hatcheries) providing goods and services to larger numbers of client farms. In addition to hubs acting as the predominant source of material moving onto farms we identified enterprises acting as bridges between identified small worlds. The presence of these bridges is a concern, since their presence has the potential to facilitate the spread of hazards (e.g. feed contaminants, infectious agents carried within feed) more readily throughout the population. An ability to predict enterprises with these network characteristics on the basis of factors such as shed capacity, enterprise type, geographic location would be useful for developing risk-based approaches to disease prevention, surveillance, detection, response and control activities.

Full Text Available The aim of this work is to present the preliminary results of a study about the prevalence of Campylobacter jejuni in poultry breeder flocks. It was examined three different breeder flocks of Bojano in Molise region. A total of 360 cloacal swabs and 80 enviromental swabs was collected. Of the 3 flocks studied, 6.9% tested were positive for Campylobacter spp. The most-prevalent isolated species is C. jejuni (8.2%. Only 3 of the 360 cloacal swabs samples examined were associated with C. coli. The environmental swabs resulted negative. This results confirms again that poultry is a reservoir of this germ.

Using annual serologic surveillance data from all poultry farms in the Netherlands during 2007-2013, we quantified the risk for the introduction of low pathogenicity avian influenza virus (LPAIV) in different types of poultry production farms and putative spatial-environmental risk factors: distance from poultry farms to clay soil, waterways, and wild waterfowl areas. Outdoor-layer, turkey (meat and breeder), and duck (meat and breeder) farms had a significantly higher risk for LPAIV introduction than did indoor-layer farms. Except for outdoor-layer, all poultry types (i.e., broilers, chicken breeders, ducks, and turkeys) are kept indoors. For all production types, LPAIV risk decreased significantly with increasing distance to medium-sized waterways and with increasing distance to areas with defined wild waterfowl, but only for outdoor-layer and turkey farms. Future research should focus not only on production types but also on distance to waterways and wild bird areas. In addition, settlement of new poultry farms in high-risk areas should be discouraged.
