    2016-10-01

    Full Text Available Salmonella spp., Campylobacter spp., and L. monocytogenes are zoonotic foodborne pathogens, associated with the consumption of contaminated foods of animal origin. In this study we determined the prevalence and risk factors associated with the presence of these microorganisms at all stages of the production system, in two Colombian poultry companies (EI-EI-I and II. In EI-I, Campylobacter spp., and Salmonella spp., were isolated from 10 % and 4.4 % of the specimens, and S. Heidelberg was the predominant serotype. Salmonella spp., was found in 6 % of hands and stool samples of workers. S. Saphra was the most prevalent serotype. In EI-II, the prevalence of Campylobacter spp., and Salmonella spp., from animal specimens was 7 % and 17 %, respectively. L. monocytogenes was not detected. This study established the prevalence of these zoonotic pathogens through the production chain and showed the presence of pathogen carriers among workers/food handlers. “Lack of medical examination of employees in the previous year” was found to be a possible risk factor for carriage of Salmonella spp.

    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 i...

    Improved monitoring tools are important for the control of Campylobacter bacteria in poultry production. Standardized reference culture methods issued by national and international standardization organizations are time-consuming, cumbersome and not amenable to automation for screening of large...... numbers of samples. The ultimate goal for rapid monitoring of Campylobacter is to prevent contaminated meat from entering the food market. Currently, real-time PCR is fulfilling abovementioned criteria to a certain extent. Further development of real-time PCR, microarray PCR, miniaturized biosensors...

  5. Mycotoxins in poultry production

    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.

    2005-01-01

    Full Text Available This paper encompasses problems related to infection caused by Salmonella spp in poultry. The need to carry out adequate control measures and to provide safe food is emphasized. Using experiences from other countries, critical control points are presented in flocks during rearing and in hatcheries. In attempt to diagnose disease as early as possible and to advise proper therapy, the significance of serology monitoring is underlined. In order to produce safe food there is a need to control disease applying our Regulations concerning eradication of Salmonella spp in poultry flocks that is given in Official paper of Republic of Serbia No 6&88 and also to include serology monitoring in poultry flocks. Veterinary practitioners are expected to perform analysis of critical control points in poultry industry as well as to determine specificity and differences in production for single farms, which would enable more effective struggle with diseases in general.

    Full Text Available Food safety and food raw materials is an important task which needs to be under government’s and public associations’ control, under enterprises which produce and sale them, and other economy departments. Nutrition is one of the most important factors influencing human health. To 70% alien substances of chemical and microbiological origin get into the human body with food. The heavy metals, nitrates, nitrites, pesticides, nitrosescomounds, mycotoxins, antibiotics, radionuclides and others are xenobiotics of chemical origin. The poultry products represented in commercial networks by poultry plants located in Saint-Petersburg and Leningrad region: “Roskar”, “Sinyavinskaya”, “North”, “Lebyazhye” were picked up for analysis. We used the bacteriological, virological, immunological, mycological, and statistical methods of research. Sanitary -hygienic or microbiological safety of food products was evaluated for the contenting of disease-causing (pathogenic microorganisms such as bacteria groups, coliforms, Staphylococcus, Salmonella and etc. in them. The poultry products sold in commercial networks of St. Petersburg were picked up for analysis. After processing the statistical were revealed 6 nosological forms where the leading position has finding colibacillosis – 27%. The number of positive samples for streptococcosis – 18%, staphylococcus – 8%, aspergillosis–2.6%, salmonellosis – 1.8%, pasteurellosis–1.6 %. The microbiological control of food products which can be the sources of infections should be regular for providing inhabitants with harmless poultry products. It is necessary to adopt and to use the modern microbiological criteria of food safety that will allow to realize the monitoring of their conformity with sanitary norms. The results of these analysis shows that the quality of poultry products sold in commercial networks of Saint Petersburg and the Leningrad region meet the standards.

  17. Current aspects of Salmonella contamination in the US poultry production chain and the potential application of risk strategies in understanding emerging hazards.

    Science.gov (United States)

    Rajan, Kalavathy; Shi, Zhaohao; Ricke, Steven C

    2017-05-01

    One of the leading causes of foodborne illness in poultry products is Salmonella enterica. Salmonella hazards in poultry may be estimated and possible control methods modeled and evaluated through the use of quantitative microbiological risk assessment (QMRA) models and tools. From farm to table, there are many possible routes of Salmonella dissemination and contamination in poultry. From the time chicks are hatched through growth, transportation, processing, storage, preparation, and finally consumption, the product could be contaminated through exposure to different materials and sources. Examination of each step of the process is necessary as well as an examination of the overall picture to create effective countermeasures against contamination and prevent disease. QMRA simulation models can use either point estimates or probability distributions to examine variables such as Salmonella concentrations at retail or at any given point of processing to gain insight on the chance of illness due to Salmonella ingestion. For modeling Salmonella risk in poultry, it is important to look at variables such as Salmonella transfer and cross contamination during processing. QMRA results may be useful for the identification and control of critical sources of Salmonella contamination.

    Directory of Open Access Journals (Sweden)

    Patrick Baron

    Full Text Available 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.

    2018-02-01

    Full Text Available Chicken is the most consumed meat in the UK, accounting for 40% of meat consumption, while national production sufficiency reaches about 80%. As a farmed animal product, chicken meat is responsible for significant freshwater appropriation volumes during its production cycle. In this context, this research aims at exploring freshwater dynamics in the UK processed poultry industry. Specifically, we develop a System Dynamics model to capture the blue water footprint, as a key sustainability performance indicator of a poultry supply chain, in the case that relevant environmental and regulatory constraints are applied. The model contributes towards investigating the impact of two potential policy-making scenarios, namely, the “water penalty” and the “water tax”, on the nexus between profitability and water usage across the poultry supply chain. Responding to the regulatory constraints, the food processor either reconfigures the supply chain through rethinking desired inventory levels or implements a water management intervention. The results indicate that investing in water-friendly production technologies could offer a greater advantage to sustainable supply chains in terms of blue water efficiency and profitability, compared to employing inventory management strategies. Overall, our analysis highlights that effective policy-making and technology-driven interventions could provide potential towards ensuring economic growth and environmental sustainability of the UK poultry sector.

    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.

    In developing countries, smallholder poultry production contributes to food security and poverty alleviation in rural areas. However, traditional poultry marketing chains have been threatened by the epidemics caused by the Highly Pathogenic Avian Influenza (H5N1) virus. The article presents a value chain analysis conducted on the traditional poultry marketing chain in the rural province of Phitsanulok, Thailand. The analysis is based on quantitative data collected on 470 backyard chicken farms, and on qualitative data collected on 28 poultry collectors, slaughterhouses and market retailers, using semi-structured interviews. The article examines the organization of poultry marketing chains in time and space, and shows how this may contribute to the spread of Highly Pathogenic Avian Influenza H5N1 in the small-scale poultry sector. The article also discusses the practices and strategies developed by value chain actors facing poultry mortality, with their economic and social determinants. More broadly, this study also illustrates how value chain analysis can contribute to a better understanding of the complex mechanisms associated with the spread of epidemics in rural communities.

    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.

  15. 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.

    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.

    Microbiologic studies were carried out in the production of poultry meat in a poultry dressing combine of the Stork system. Examined were a total of 125 washing samples taken at the 9th, 11th and 15th hour from the scalding vat, the cooling vat, the machine of eviscerating and the skin surface after plucking, eviscerating and shower washing and prior to packing the carcasses. It was found that the count of aerobic organisms continuously rose during the technologic processing of the slaughtered birds with regard to the surface of the carcasses, the peak values of the total counts and that of coliforms being reached during evisceration. It was further established that shower washing of the carcasses immediately following evisceration guaranteed a washing effect so far as the microflora on the surface was concerned, amounting to 77.60 per cent. So far as the coliform bacteria was concerned this effect was found to be equal to 89.78 per cent. The total count of aerobic microflora on the surface of carcasses prior to packing was found to vary within the range of 3000 to 72000, while the count of coliforms ranged from 100 to 1800/cm2.

    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.

    2015-06-01

    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.

    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.

    Full Text Available Broiler production is a significant economic activity in Brazil, and employs a large number of stockpeople in the integration process. Considering that the stockperson's perception may lead to better performance of his/her tasks and flock handling, this study aimed at verifying possible interactions between poultry productivity and stockperson's perception, emotions, and motivation. The study methodology considered two aspects: qualitative analysis, using Ergonomic Work Analysis, with observational method, and by applying a questionnaire and interview, and classification of the answers into positive relationship and "affection" to the job or negative relationship and "disaffection" to the job; and quantitative analysis, applying the Test of Hypothesis for Comparison of Means both for total flock mortality and Weight Equivalent Index data. Qualitative results showed that the stockpeople were aware that the housing environment causes specific health symptoms, as well as they presented different responses as to flock handling. Quantitative data showed a correlation between reduction of total flock mortality and positive relationship towards the broilers and "affection" to the job, whereas no statistical evidence that the same individuals influenced broiler Weight Equivalent Index was detected.

  20. Application of Probiotics in Poultry Production

    Directory of Open Access Journals (Sweden)

    Martin Král

    2012-05-01

    Full Text Available In the last years probiotics have constantly increased in importance and aroused growing interest in animal nutrition. Probiotics are live microorganisms thought to be beneficial to the host organism. The bacteria of the probiotic attach to the intestinal mucosa, thereby forming a physical barrier that blocks the attachment of pathogenic bacteria. The mode of action of probiotics in poultry includes maintaining normal intestinal microflora by competitive exclusion and antagonism, altering metabolism by increasing digestive enzyme activity and decreasing bacterial enzyme activity and ammonia production, improving feed intake and digestion and neutralizing enterotoxins and stimulating the immune system. In experiment we research effect of probiotic on the performance of broiler chickens. A total number of 200 one day old broiler chickens were distributed to two dietary groups. Broiler chickens in control group were fed with standard feed mixture and experimental group with probiotics mixed with feed mixture. Body weight and GIT pH were recorded. Average body weight on the end of experiment in experimental group was 1493.6 g and 1689.6 g in control group. Average pH in experimental group was 2.79 in stomach, 6.28 in small intestine, 6.81 and 6.89 in caecum. In control group was average pH 3.54 in stomach, 6.41 in small intestine, 6.74 and 6.80 in caecum.

    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)

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

    2018-03-01

    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.

  6. 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.

  7. 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

    2002-01-01

    In order to investigate the production characteristics of village poultry in Madagascar, a cross sectional survey was done in May, 1999 in zone 1 and in June 1999 in zone 2. Furthermore, a longitudinal survey was done in 33 farms in the two zones during a 12 month period providing information on flock dynamics and causes of mortality. The indigenous chicken in Madagascar represents 91% of the total poultry population. Each farm has on average 11 birds, which survive by scavenging. The average productivity is 33.3 eggs/hen/year and 2.76 clutches/hen/year. The average hatchability is 77.8% and 75% of the eggs are used for renewing the flock. Mortality figures are very high: 42.3% of the chicks die before weaning and 34.5% of the growers die before becoming adults. Mortality of adults is on average 3 1.4%. Mortality is due to various factors, but is mainly due to internal parasites in the chicks (38.5%), especially during the dry season. Newcastle disease (ND) is the most important infectious cause of mortality causing more than 68.8% of the deaths in growers and 75% in the adults. Post mortem results confirmed serological information using the indirect haemagglutination test indicating the importance of ND. However, further study is necessary to identify the wild strains of ND that might circulate in Madagascar. (author) [fr

    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.

    The poultry industry has a significant importance on national economy. It is a popular industry for the small holders with tremendous contribution to Gross Domestic Product (GDP) and employment creation. Poultry feed cost represents over sixty (60) percent of the total cost of poultry production; consequently, efficient feed formulation practice is required for a sustainable poultry industry. Many Ghanaian poultry farmers, however, employ inefficient methods like rule of thumb, experiences, a...

  14. 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.

  16. How can we improve the environmental sustainability of poultry production?

    Science.gov (United States)

    Leinonen, Ilkka; Kyriazakis, Ilias

    2016-08-01

    The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40-60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

  2. 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.

    Full Text Available Aim: The aim of this study was to characterize virulent Escherichia coli isolated from different poultry species and poultry farm workers using enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR genotyping. Materials and Methods: Fecal swabs from different poultry species (n=150 and poultry farm workers (n=15 were analyzed for E. coli and screened for virulence genes (stx1, stx2, eaeA, and hlyA by multiplex PCR. Virulent E. coli was serotyped based on their "O" antigen and then genotyped using ERIC-PCR. Results: A total of 134 E. coli isolates (122/150 from poultry and 12/15 from farm workers were recovered. Virulence genes were detected in a total of 12 isolates. Serological typing of the 12 virulent E. coli revealed nine different serotypes (O2, O49, O60, O63, O83, O101, O120, UT, and Rough. ERIC-PCR genotyping allowed discrimination of 12 virulent E. coli isolates into 11 ERIC-PCR genotypes. The numerical index of discrimination was 0.999. Conclusion: Our findings provide information about the wide genetic diversity and discrimination of virulent E. coli in apparently healthy poultry and poultry farm workers of Andhra Pradesh (India based on their genotype.

    2017-04-11

    The routine use of antibiotics in agriculture has contributed to an increase in drug-resistant bacterial pathogens in animals that can potentially be transmitted to humans. In 2000, the World Health Organization identified resistance to antibiotics as one of the most significant global threats to public health and recommended that the use of antibiotics as additives in animal feed be phased out or terminated, particularly those used to treat human infections. Research is currently being carried out to identify alternative antimicrobial compounds for use in animal production. A number of studies, mostly in vitro, have provided evidence indicating that bacteriocins, which are antimicrobial peptides of bacterial origin, may be promising alternatives to conventional antibiotics in poultry and swine production. This review provides an update on bacteriocins and their potential for use in the poultry and swine industries.

    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.

    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.

    2015-11-01

    Antimicrobial resistance profiles and presence of resistance determinants and integrons were evaluated in Salmonella enterica strains from Brazilian poultry. The analysis of 203 isolates showed that those from the poultry environment (88 isolates) were significantly more resistant to antimicrobials than isolates from other sources, particularly those isolated from poultry by-product meal (106 isolates). Thirty-seven isolates were resistant to at least three antimicrobial classes. Class 1 integrons were detected in 26 isolates, and the analysis of the variable region between the 5' conserved segment (CS) and 3' CS of each class 1 integron-positive isolate showed that 13 contained a typical 3' CS and 14 contained an atypical 3' CS. One Salmonella Senftenberg isolate harbored two class 1 integrons, showing both typical and atypical 3' CSs. The highest percentage of resistance was found to sulfonamides, and sul genes were detected in the majority of the resistant isolates. Aminoglycoside resistance was detected in 50 isolates, and aadA and aadB were present in 28 and 32 isolates, respectively. In addition, strA and strB were detected in 78.1 and 65.6% isolates resistant to streptomycin, respectively. Twenty-one isolates presented reduced susceptibility to β-lactams and harbored bla(TEM), bla(CMY), and/or bla(CTX-M). Forty isolates showed reduced susceptibility to tetracycline, and most presented tet genes. These results highlight the importance of the environment as a reservoir of resistant Salmonella, which may enable the persistence of resistance determinants in the poultry production chain, contributing, therefore, to the debate regarding the impacts that antimicrobial use in animal production may exert in human health.

    Coccidiosis is a self-limiting disease that is universally present in poultry operations, causing extensive damage to the intestinal lining of the bird. Global economic losses from coccidiosis are estimated to be $3 billion per year. In-feed anticoccidial use has been the predominant form of coccidiosis control. However, due to widespread emergence of antimicrobial resistance, concerns have been raised regarding the safety of anticoccidials and the potential impact on human, animal, and environmental health. To investigate the benefits, risks, and alternatives to anticoccidial use, a comprehensive review of recent literature was conducted. Several live vaccines are available, which, when used in combination with anticoccidials, have been shown to help restore sensitivity of infective parasites. However, their use has been limited because of increased cost; increased susceptibility to bacterial enteritis; challenges with consistent application; and slow development of immunity. Various alternative feed products are available, but do not have a direct anticoccidial effect, and few studies have demonstrated consistent field efficacy of these products. Consumer and environmental safety of anticoccidials is monitored and assessed by governing bodies. Furthermore, there is a lack of current evidence to indicate that bacterial resistance poses a public health concern. The findings from this review indicate that in the absence of alternatives, poultry production is optimized by using anticoccidials, benefiting all three pillars of sustainability, including social (bird health, welfare, and food safety), economic (production efficiency), and environmental aspects.

    2015-01-01

    Full Text Available Summary.To solve the problem of disposing of huge volumes of cellulose waste from sugar production in the form of beet pulp and waste of poultry farms in the form of poultry manure is proposed to use the joint use of two methods of thermal processing of waste - pyrolysis and gasification. The possibility of using pyrolysis applied to the waste are confirmed by experimental results. Based on the results of laboratory studies of the properties of by-products resulting from the thermal processing of the feedstock, it is proposed complex processing to produce useful products, to be implemented in the form of marketable products, and the organization's own process energy utilization. Developed flow diagram of an integrated processing said waste comprises 3 sections, which successively carried out: pyrolytic decomposition of the feedstock to obtain a secondary product in the form of solid, liquid and gas fractions, the gasification of solids to obtain combustible gas and separating the liquid fraction by distillation to obtain valuable products. The main equipment in the first region is the pyrolysis reactor cascade condensers; the second section - gasifiers layers and stream type; the third - one or more distillation columns with the necessary strapping. Proper power supply installation is organized by the use of the heat produced during combustion of the synthesis gas for heating and gasification reactor. For the developed scheme presents calculations of the heat balance of the installation, supporting the energy efficiency of the proposed disposal process. Developments carried out in the framework of the project the winner of the Youth Prize Competition Government of Voronezh region to support youth programs in the 2014-2015.

  2. Assessment of Meat and Poultry Product Recalls Due to Salmonella Contamination: Product Recovery and Illness Prevention.

    Seys, Scott A; Sampedro, Fernando; Hedberg, Craig W

    2017-08-01

    Data from the recalls of meat and poultry products from 2000 through 2012 due to Salmonella contamination were used to assess the factors associated with the recovery of the recalled product and to develop quantitative models to estimate the number of illnesses prevented by recalls. The percentage of product recovered following a recall action was not dependent on establishment size, recall expansions, complexity of the distribution chain, type of distribution, amount of time between the production and recall dates, or number of pounds of product recalled. However, illness-related recalls were associated with larger amounts of recalled product, smaller percentages of recalled product recovered, a greater number of days between the production date and recall date, and nationwide distribution than were recalls that were not illness related. In addition, the detection of recall-associated illnesses appeared to be enhanced in states with strong foodborne illness investigation systems. The number of Salmonella illnesses prevented by recalls was based on the number of illnesses occurring relative to the number of pounds consumed, which was then extrapolated to the number of pounds of recalled product recovered. A simulation using a program evaluation and review technique probability distribution with illness-related recalls from 2003 through 2012 estimated that there were 19,000 prevented Salmonella illnesses, after adjusting for underdiagnosis. Recalls not associated with illnesses from 2000 through 2012 prevented an estimated additional 8,300 Salmonella illnesses, after adjusting for underdiagnosis. Although further improvements to ensure accurate and complete reporting should be undertaken, our study demonstrates that recalls are an important tool for preventing additional Salmonella illnesses. Moreover, additional training resources dedicated to public health agencies for enhancing foodborne illness detection, investigations, and rapid response and reporting would

    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 epidemiologica...

    Full Text Available The use of antibiotics in food-producing animals has significantly increased animal health by lowering mortality and the incidence of diseases. Antibiotics also have largely contributed to increase productivity of farms. However, antibiotic usage in general and relevance of non-therapeutic antibiotics in feed (growth promoters need to be reevaluated especially because bacterial pathogens of humans and animals have developed and shared a variety of antibiotic resistance mechanisms that can easily spread within microbial communities. In Canada, poultry production involves more than 2,600 regulated chicken producers. There are several antibiotics approved as feed additives available for poultry farmers. Feed recipes and mixtures greatly vary geographically and from one farm to another, making links between use of a specific antibiotic feed additive and production yields or selection of specific antibiotic-resistant bacteria difficult to establish. Many on-farm studies have revealed the widespread presence of antibiotic-resistant bacteria in broiler chickens. While sporadic reports linked the presence of antibiotic-resistant organisms to the use of feed supplemented with antibiotics, no recent studies could clearly demonstrate the benefit of antimicrobial growth promoters on performance and production yields. With modern biosecurity and hygienic practices, there is a genuine concern that intensive utilization of antibiotics or use of antimicrobial growth promoters in feed might no longer be useful. Public pressure and concerns about food and environmental safety (antibiotic residues, antibiotic-resistant pathogens have driven researchers to actively look for alternatives to antibiotics. Some of the alternatives include pre- and probiotics, organic acids and essential oils. We will describe here the properties of some bioactive molecules, like those found in cranberry, which have shown interesting polyvalent antibacterial and immuno

    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

    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.

    Full Text Available Introduction. Analyzing the current processes of global sales and sales interaction over the past two decades shows that the world’s system of exchanges has undergone significant changes that have been caused by a multitude of factors. The formation of a complex model of global production, determined by the peculiarities of the transformation of individual economies’ growth models, the specifics of their industrialization and the forms of development of their national production business, its institutional and market-wise restructuring and the degree of inclusion in the system of international division of labor. The change in the level and depth of the specialization of individual countries in the field of production and sale of products, in turn, has accelerated the overcoming of economic distance (which is measured by the cost of transport and information services. Based on the above, namely, within the framework of forming a new model of global production, the issue of studying the role and value of supply chains in this model is made relevant. Aim and tasks. The purpose of the article is to study the modern transformation of supply chains within the global production system. The findings will allow to determine what exactly needs to be done in the direction of further redeveloping the regulatory tools of global supply chain management. Research results. The article presents the results of studying the transformation of supply chains’ role in global production. It is determined that taking into account the existing specificity of industrialization and fragmentation of national production, as well as the rapid spread of the results of scientific and technological progress in the world economy, there is a need for a more thorough study of this change. As a result of analyzing open source statistical data, a conclusion was reached regarding the transition from the competition of individual business entities to the competition of global

    Agro-ecological conditions associated with the spread and persistence of highly pathogenic avian influenza (HPAI) are not well understood, but the trade of live poultry is suspected to be a major pathway. Although market chains of live bird trade have been studied through indirect means including interviews and questionnaires, direct methods have not been used to identify movements of individual poultry. To bridge the knowledge gap on quantitative movement and transportation of poultry, we introduced a novel approach for applying telemetry to document domestic duck movements from source farms at Poyang Lake, China. We deployed recently developed transmitters that record Global Positioning System (GPS) locations and send them through the Groupe Spécial Mobile (GSM) cellular telephone system. For the first time, we were able to track individually marked ducks from 3 to 396 km from their origin to other farms, distribution facilities, or live bird markets. Our proof of concept test showed that the use of GPS-GSM transmitters may provide direct, quantitative information to document the movement of poultry and reveal their market chains. Our findings provide an initial indication of the complexity of source-market network connectivity and highlight the great potential for future telemetry studies in poultry network analyses.

    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 %.

    2015-10-01

    Surveillance and control of food-borne human pathogens, such as Listeria monocytogenes, is a critical aspect of modern food safety programs at food production facilities. This study evaluated contamination patterns of Listeria species at a poultry food production facility, and evaluated the efficacy of procedures to control the contamination and transfer of the bacteria throughout the plant. The presence of Listeria species was studied along the production chain, including raw ingredients, food-contact, non-food-contact surfaces, and finished product. All isolates were sub-typed by pulsed-field gel electrophoresis (PFGE) to identify possible entry points for Listeria species into the production chain, as well as identifying possible transfer routes through the facility. The efficacy of selected in-house sanitizers against a sub-set of the isolates was evaluated. Of the 77 different PFGE-types identified, 10 were found among two or more of the five categories/areas (ingredients, food preparation, cooking and packing, bulk packing, and product), indicating potential transfer routes at the facility. One of the six sanitizers used was identified as unsuitable for control of Listeria species. Combining PFGE data, together with information on isolate location and timeframe, facilitated identification of a persistent Listeria species contamination that had colonized the facility, along with others that were transient.

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

    2018-06-01

    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.

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

    2011-01-01

    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.

    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)

    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.

    The objective of this study was to investigate a clonal relationship among thermotolerant Campylobacter spp. isolates from different stages of the poultry meat supply chain in Argentina. A total of 128 thermotolerant Campylobacter spp. (89 C. jejuni and 39 C. coli) isolates from six poultry meat chains were examined. These isolates were from: a) hens from breeder flocks, b) chickens on the farm (at ages 1 wk and 5 wk), c) chicken carcasses in the slaughterhouse, and d) chicken carcasses in the retail market. Chickens sampled along each food chain were from the same batch. Campylobacter spp. isolates were analyzed using pulsed-field gel electrophoresis to compare different profiles according to the source. Clustering of C. jejuni isolates resulted in 17 profiles, with four predominant genotypes and many small profiles with just a few isolates or unique patterns, showing a very high degree of heterogeneity among the C. jejuni isolates. Some clusters included isolates from different stages within the same chain, which would indicate a spread of strains along the same poultry meat chain. Moreover, twenty-two strains of C. coli clustered in seven groups and the remaining 17 isolates exhibited unique profiles. Evidence for transmission of thermotolerant Campylobacter spp. through the food chain and cross contamination in the slaughterhouses were obtained. This collective evidence should be considered as the scientific basis to implement risk management measures to protect the public health. Copyright © 2017 Asociación Argentina de Microbiología.

    2018-01-01

    Poultry meat is an indispensable source of animal protein in human growth and development, so it is in great demand by people all over the world. Poultry meat has several advantages, namely the quality of nutrition is good enough, delicious taste, relatively affordable price, easy to get and accepted all levels of society with diverse backgrounds. The era of globalization requires competitive products, such as chicken meat in Indonesia, the current chicken meat industry is not only based on high production capacity and decreased production costs but also chicken products are safe to eat. As a consequence of trade liberalization, the poultry industry faces the threat of competition with cheaper products with better quality. The food safety of chicken meat starts from the farm, processing process until consumed. Food safety is a requirement of food products that must be handled by involving government, industry and consumers.

    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.

    Chandra, Charu; Grabis, Janis

    2001-10-01

    Coordination of different and often contradicting interests of individual supply chain members is one of the important issues in supply chain management because the individual members can not succeed without success of the supply chain and vice versa. This paper investigates a supply chain dynamic production planning problem with emphasis on coordination. A planning problem is formally described using a supply chain kernel, which defines supply chain configuration, management policies, available resources and objectives both at supply chain or macro and supply chain member or micro levels. The coordinated model is solved in order to balance decisions made at the macro and micro levels and members' profitability is used as the coordination criterion. The coordinated model is used to determine inventory levels and production capacity across the supply chain. Application of the coordinated model distributes costs burden uniformly among supply chain members and preserves overall efficiency of the supply chain. Influence of the demand series uncertainty is investigated. The production planning model is a part of the integrated supply chain decision modeling system, which is shared among the supply chain members across the Internet.

    Wild waterfowl are the reservoir for avian influenza viruses (AIVs), a family of RNA viruses that may cause mild sickness in waterbirds. Emergence of H5N1, a highly pathogenic avian influenza (HPAI) strain, causing severe disease and mortality in wild birds, poultry and humans, had raised concerns about the role of wild birds in possible transmission of the disease. In this review, the link between rice production systems, poultry production systems, and wild bird ecology is examined to assess the extent to which these interactions could contribute towards the persistence and evolution of HPAI H5N1. The rice (Oryza sativa) and poultry production systems in Asia described, and then migration and movements of wild birds discussed. Mixed farming systems in Asia and wild bird movement and migration patterns create opportunities for the persistence of low pathogenic AIVs in these systems. Nonetheless, there is no evidence of long-term persistence of HPAI viruses (including the H5N1 subtype) in the wild. There are still significant gaps in the understanding of how AIVs circulate in rice systems. A better understanding of persistence of AIVs in rice farms, particularly of poultry origins, is essential in limiting exchange of AIVs between mixed-farming systems, poultry and wild birds.

  7. 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.

  8. Campylobacteriosis: the role of poultry meat.

    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.

    2016-07-01

    Limited resources are one of the major constraints in effective disease monitoring and control in developing countries. This paper examines the pig and poultry market chains of four targeted Pacific Island countries and territories (PICTs): Fiji, Papua New Guinea, Solomon Islands and Vanuatu and combines them with a risk pathway analysis to identify the highest risk areas (risk hotspots) and risky practices and behaviours (risk factors) of animal disease introduction and/or spread, using highly pathogenic avian influenza (HPAI) and foot-and-mouth disease (FMD) as model diseases because of their importance in the region. The results show that combining a market chain analysis with risk pathways is a practical way of communicating risk to animal health officials and improving biosecurity. It provides a participatory approach that helps officials to better understand the trading regulations in place in their country and to better evaluate their role as part of the control system. Common risk patterns were found to play a role in all four PICTs. Legal trade pathways rely essentially on preventive measures put in place in the exporting countries while no or only limited control measures are undertaken by the importing countries. Legal importations of animals and animal products are done mainly by commercial farms which then supply local smallholders. Targeting surveillance on these potential hotspots would limit the risk of introduction and spread of animal diseases within the pig and poultry industry and better rationalize use of skilled manpower. Swill feeding is identified as a common practice in the region that represents a recognized risk factor for dissemination of pathogens to susceptible species. Illegal introduction of animals and animal products is suspected, but appears restricted to small holder farms in remote areas, limiting the risk of spread of transboundary animal diseases along the market chain. Introduction of undeclared goods hidden within a legal

    The transportation of poultry and related products for international trade contributes to transboundary pathogen spread and disease outbreaks worldwide. To prevent pathogen incursion through poultry products, many countries have regulations about animal health and poultry product quarantine. However, in Japan, animal products have been illegally introduced into the country in baggage and confiscated at the airport. Lately, the number of illegally imported poultry and the incursion risk of transboundary pathogens through poultry products have been increasing. In this study, we isolated avian influenza viruses (AIVs) from raw poultry products illegally imported to Japan by international passengers. Highly (H5N1 and H5N6) and low (H9N2 and H1N2) pathogenic AIVs were isolated from raw chicken and duck products carried by flight passengers. H5 and H9 isolates were phylogenetically closely related to viruses isolated from poultry in China, and haemagglutinin genes of H5N1 and H5N6 isolates belonged to clades 2.3.2.1c and 2.3.4.4, respectively. Experimental infections of H5 and H9 isolates in chickens and ducks demonstrated pathogenicity and tissue tropism to skeletal muscles. To prevent virus incursion by poultry products, it is important to encourage the phased cleaning based on the disease control and eradication and promote the reduction in contamination risk in animal products. © 2017 Blackwell Verlag GmbH.

  14. Alternative agriculture as a substitute for environmental remediation. Production of poultry in radiologically contaminated areas

    1995-01-01

    Exploiting the physiological and ecological characteristics of domesticated species has seldom been considered as a means of returning radiologically contaminated areas to safe agricultural production. However, the proper choice of cultivated and domesticated species, together with appropriate husbandry practices, may allow safe production of foods, fibre and energy. As an example, factors that could permit safe production of food products for human consumption from poultry raised in contaminated areas are considered. These factors include radionuclide transfer from the environment into poultry and methods for reducing radionuclide uptake and/or decontaminating chickens to yield acceptable food products. Studies of growth and feed intake rates of chickens under intensive management and free-ranging husbandries, 137 Cs uptake by chickens exposed to contaminated sediments, potential effects of husbandry on 137 Cs concentrations and 137 Cs elimination by chickens after removal of contaminated feed are described. Data from these and other studies are combined in simulation models of the 13 '7Cs kinetics of chickens. Chicken product 137 Cs concentrations ([ 137 Cs]s) decrease with increases in body mass, apparently as a result of decreasing mass specific intake rates. Husbandries that increase contaminant intake (e.g. free-ranging rearing conditions versus brooder house production) or access to contaminated soils (e.g. scattering feed directly onto contaminated solid versus the use of feeders) increase total body [ 137 Cs]s. However, model simulations indicate that it is possible to produce safe poultry products (especially eggs) at all but unrealistically high feed contamination levels. Even when dietary 137 Cs levels produce [ 137 Cs]s in poultry products that exceed acceptable limits, the high metabolism of poultry leads to a rapid decrease in [ 137 Cs]s once the chickens are placed on uncontaminated rations. This permits the use of contaminated feed or forage for

    Little is known about Salmonella serovars circulating in backyard poultry and swine populations worldwide. Backyard production systems (BPS) that raise swine and/or poultry are distributed across Chile, but are more heavily concentrated in central Chile, where industrialized systems are in close contact with BPS. This study aims to detect and identify circulating Salmonella serovars in poultry and swine raised in BPS. Bacteriological Salmonella isolation was carried out for 1744 samples collected from 329 BPS in central Chile. Faecal samples were taken from swine, poultry, geese, ducks, turkeys and peacocks, as well as environmental faecal samples. Confirmation of Salmonella spp. was performed using invA-polymerase chain reaction (PCR). Identification of serovars was carried out using a molecular serotyping approach, where serogroups were confirmed by a multiplex PCR of Salmonella serogroup genes for five Salmonella O antigens (i.e., D, B, C1, C2-C3, and E1), along with two PCR amplifications, followed by sequencing of fliC and fljB genes. A total of 25 samples (1·4% of total samples) from 15 BPS (4·6 % of total sampled BPS) were found positive for Salmonella. Positive samples were found in poultry (chickens and ducks), swine and environmental sources. Molecular prediction of serovars on Salmonella isolated showed 52·0% of S. Typhimurium, 16·0% of S. Infantis, 16·0% S. Enteritidis, 8·0% S. Hadar, 4·0% S. Tennessee and 4·0% S. Kentucky. Poor biosecurity measures were found on sampled BPS, where a high percentage of mixed confinement systems (72·8%); and almost half of the sampled BPS with improper management of infected mortalities (e.g. selling the carcasses of infected animals for consumption). Number of birds other than chickens (P = 0·014; OR = 1·04; IC (95%) = 1·01-1·07), mixed productive objective (P = 0·030; OR = 5·35; IC (95%) = 1·24-27·59) and mixed animal replacement origin (P = 0017; OR = 5·19; IC (95%) = 1·35-20·47) were detected as

    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 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

    The SELEVER study is designed to evaluate the impact of an integrated agriculture-nutrition package of interventions (including poultry value chain development, women's empowerment activities, and a behavior change communications strategy to promote improved diets and feeding, care, and hygiene practices) on the diets, health, and nutritional status of women and children in Burkina Faso. This paper presents the rationale and study design. The impact evaluation involves a cluster randomized controlled trial design that will be implemented in 120 rural communities/villages within 60 communes supported by SELEVER in the Boucle de Mouhoun, Centre-Ouest, and Haut-Bassins regions of Burkina Faso. Communities will be randomly assigned to one of three treatment arms, including: (1) SELEVER intervention group; (2) SELEVER with an intensive WASH component; and (3) control group without intervention. Primary outcomes include the mean probability of adequacy of diets for women and children (aged 2-4 years at baseline), infant and young child feeding practices of caregivers of children aged 0-2 years, and household poultry production and sales. Intermediate outcomes along the agriculture and nutrition pathways will also be measured, including child nutrition status and development. The evaluation will follow a mixed-methods approach, including a panel of child-, household-, community-, and market-level surveys, and data collection points during post-harvest and lean seasons, as well as one year after implementation completion to examine sustainability. To our knowledge, this study is the first to rigorously examine from a food systems perspective, the simultaneous impact of scaling-up nutrition-specific and nutrition-sensitive interventions through a livestock value-chain and community-intervention platform, across nutrition, health, and agriculture domains. The findings of this evaluation will provide evidence to support the design of market-based nutrition

    Poultry feeds are prone to fungal growth and mycotoxin production during processing. The identification of biota with the ability to produce mycotoxins is essential. The aims of this study were (1) to monitor the mycobiota counts at different stages of poultry feed processing; (2) to determine the occurrence of Aspergillus species; (3) to evaluate the natural incidence of aflatoxins and ochratoxin A. The ability of Aspergillus spp. and its teleomorphs isolated here to produce these toxins was also investigated. Samples (144) were collected at random from a factory in Brazil. The occurrence of Aspergillus and Eurotium species was demonstrated on DRBC and DG18 media and the production of aflatoxins and ochratoxin A and their natural incidence were determined by TLC and HPLC methods. A. flavus and E. chevalieri were the most prevalent species isolated. Fungal contamination was not found after the pelleting process, though Aspergillus and Eurotium species were recovered from trough samples. High levels of aflatoxin and ochratoxin A producers were found at all stages of poultry feed processing. Also, high natural contamination with aflatoxins and ochratoxin A was found in the samples. Contact of feed with remainder poultry feed could lead to fungal contamination, so the risk of aflatoxin and/or ochratoxin A contamination of feed must be taken into account.

    Sodium-reduced packaged food products are increasingly available to consumers; however, it is not clear whether they are suitable for inclusion in a potassium-reduced diet. For individuals with impaired renal potassium excretion caused by chronic kidney disease and for those taking certain medications that interfere with the rennin-angiotensin aldosterone axis, the need to limit dietary potassium is important in view of the risk for development of hyperkalemia and fatal cardiac arrhythmias. The primary objective of this study was to determine the impact of the reduction of sodium in packaged meat and poultry products (MPPs) on the content of potassium and phosphorus from food additives. This was a cross-sectional study comparing chemically analyzed MPPs (n=38, n=19 original, n=19 sodium-reduced), selected from the top three grocery chains in Canada, based on market share sales. All MPPs with a package label containing a reduced sodium content claim together with their non-sodium-reduced packaged MPP counterparts were selected for analysis. The protein, sodium, phosphorus, and potassium contents of sodium-reduced MPPs and the non-sodium-reduced (original) MPP counterparts were chemically analyzed according to the Association of Analytical Communities official methods 992.15 and 984.27 and compared by using a paired t test. The frequency of phosphorus and potassium additives appearing on the product labels' ingredient lists were compared between groups by using McNemar's test. Sodium-reduced MPPs (n=19) contained 44% more potassium (mg/100 g) than their non-sodium-reduced counterparts (n=19) (mean difference [95% CI): 184 [90-279]; P=0.001). The potassium content of sodium-reduced MPPs varied widely and ranged from 210 to 1,500 mg/100 g. Potassium-containing additives were found on the ingredient list in 63% of the sodium-reduced products and 26% of the non-sodium-reduced products (P=0.02). Sodium-reduced MPPs contained 38% less sodium (mg/100 g) than their non

    Linear accelerators, commonly called Linacs, are being used for different industrial processes. This kind of machine produces high power electron beams and can treat many products with a high throughput. The main application of a Linac is the sterilization of medical disposable devices, polymerization and decontamination of food products. Salmonella commonly contaminates poultry. Thanks to E-beam treatment, it eradicates the pathogen quickly and permits the use of meat that should have been thrown away because of its infection. The world's first Linac dedicated to treat mechanically deboned poultry meat is located in Brittany at the Societe des Proteines Industrielles. It is a Thomson CSF Linac product, the CIRCE II, with an energy of 10 MeV and a power of 10 kW. This Linac has been used for more than 8 years, and its technology is fully proven. (author)

  14. Vaccination of chickens against coccidiosis ameliorates drug resistance in commercial poultry production

    Directory of Open Access Journals (Sweden)

    H. David Chapman

    2014-12-01

    Full Text Available Drug resistance is a problem wherever livestock are raised under intensive conditions and drugs are used to combat parasitic infections. This is particularly true for the anticoccidial agents used for the prevention of coccidiosis caused by protozoa of the apicomplexan genus Eimeria in poultry. Resistance has been documented for all the dozen or so drugs approved for use in chickens and varying levels of resistance is present for those currently employed. A possible solution may be the introduction of drug-sensitive parasites into the houses where poultry are raised so that they may replace such drug-resistant organisms. This can be achieved by utilizing live vaccines that contain strains of Eimeria that were isolated before most anticoccidial compounds were introduced. Such strains are inherently drug-sensitive. Practical proposals to achieve this objective involve the alternation of vaccination with medication (known as rotation programs in successive flocks reared in the same poultry house. A proposal for a yearly broiler production cycle involving chemotherapy and vaccination is presented. There are few, if any, examples in veterinary parasitology where it has proved possible to restore sensitivity to drugs used to control a widespread parasite. Further research is necessary to ascertain whether this can result in sustainable and long-term control of Eimeria infections in poultry.

  18. Multi-Criteria Analysis to Prioritize Energy Sources for Ambience in Poultry Production

    Directory of Open Access Journals (Sweden)

    DC Collatto

    Full Text Available ABSTRACT This paper intends to outline a model of multi-criteria analysis to pinpoint the most suitable energy source for heating aviaries in poultry broiler production from the point of view of the farmer and under environmental logic. Therefore, the identification of criteria was enabled through an exploratory study in three poultry broiler production units located in the mountain region of Rio Grande do Sul. In order to identify the energy source, the Analytic Hierarchy Process was applied. The criteria determined and validated in the research contemplated the cost of energy source, leadtime, investment in equipment, energy efficiency, quality of life and environmental impacts. The result of applying the method revealed firewood as the most appropriate energy for heating. The decision support model developed could be replicated in order to strengthen the criteria and energy alternatives presented, besides identifying new criteria and alternatives that were not considered in this study.

    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

  5. Use of radiosensitivity to identify irradiated fresh poultry products

    Copin, M.P.; Bourgeois, C.M.

    1991-01-01

    Microbiological comparison between irradiated and non-irradiated foodstuff has been studied for a long time as a way to detect whether a foodstuff has been irradiated or not. Generally, the proposed methods are based on the fact that ionization select species of bacteria which are recognized to be radioresistant. So reduction or elimination of known radiation sensitive microbes from the normal endogenous microflora could give an indication that the foodstuff has been irradiated, predominance of known radioresistant bacteria should be another indication. In the present work, we try to develop a test based on the radiosensitivity of the bacteria independently of their place. These first experiments show that the determination of radiosensitivity of strains isolated from a product or even of global radioresistance of mesophilic microflora could indicate if this product has been previously submitted to ionizing radiations.

    Silver nanoparticles (AgNPs) are of interest due to their antimicrobial activity and are seen as potential candidates to replace antibiotics in animal husbandry. A few studies have focused on this new application, but they lack any considerations about residual accumulation of AgNPs in edible animal tissues and animal products. In this research, a 22 day in vivo study was carried out by oral administration of 20 nm spherical PVP coated AgNPs to hens. Six doses of approximately 1 mg kg -1 of AgNPs-PVP each were administered to animals throughout the experimentation. Atomic absorption spectroscopy (AAS) was used for quantitative determination of residual total Ag in different organs and matrices. The analyses showed that Ag accumulates in livers (concentration ranging from 141 μg kg -1 to 269 μg kg -1 ) and yolks (concentration ranging from 20 μg kg -1 to 49 μg kg -1 ) but not in muscles, kidneys, and albumen belonging to hens of the treated group (tG2). Ag was not detected in animals of the control group (uG1) (i.e., total Ag animals. spICP-MS highlighted that part of residual Ag found in livers (about 5-20%) is in NP form with an average dimension of approximately 20 nm. SEM-EDX technique confirmed the presence of AgNPs only in livers of treated animals. The results show that feeding AgNPs to hens may become a source of consumer exposure to AgNPs. As far as we know this is the first study showing transfer of AgNPs or reaction products thereof from animal feed to animal products.

    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.

    A study of the traditional poultry production system in the Bamenda area in Cameroon was conducted using a baseline survey covering the rainy and dry seasons from December, 1999-June, 2000. This survey focused mainly on the characterization of the flock size and structure, housing system, feeding, marketing of chickens, health, flock breeding and ownership patterns. The results showed that among poultry species surveyed, chickens predominated in all households, followed by ducks (15.4%) and pigeons (7.7%). A cock had access to about 2-3 hens and one hen had a brood of 1-3 chicks at a time with an overall higher hen/cock and chicks/hen ratio for the dry season. Production and reproduction performance results showed that hens laid about 3 clutches of 12 eggs per year and this was similar for both seasons. The most predominant disease symptoms in descending order of importance included diarrhoea, coughing and ectoparasitism. Although the overall disease occurrence rate was high in growers, chicks suffered from many unclassified ailments. From the survey results, ethno-veterinary therapy featured as the most frequent method of treating diseases in rural poultry in the Bamenda area. With regard to flock ownership and management patterns, the survey results showed that women owned birds in the majority of the cases (38.5%) followed by men (23.1%) and children (15.3%). Although all gender categories were involved in village chicken management, the greatest participation came from women, followed by men, children and the family as a whole. Construction of shelters was mainly a job for the men with assistance from the children. Women were mostly involved in providing water to the birds, preparing supplementation rations and selling eggs. Finally, with regard to household decision making on issues related to poultry management, men played the leading role (66.7%), followed by women (28.4%) and then children (3.7%). (author)

    In this study, the possibility of extending shelf life of marinated poultry meat products by high pressure processing was evaluated. Relevant spoilage and pathogenic strains were selected and used as target microorganisms (MOs) for challenge experiments. Meat and brine were inoculated with MOs and treated at 450 MPa, 4 °C for 3 min. The results of inactivation show a decreasing pressure tolerance in the series Lactobacillus > Arcobacter > Carnobacterium > Bacillus cereus > Brochothrix thermosphacta > Listeria monocytogenes. Leuconostoc gelidum exhibited the highest pressure tolerance in meat. A protective effect of poultry meat was found for L. sakei and L. gelidum. In parallel, the influence of different marinade formulations (pH, carbonates, citrates) on protein structure changes during a pressure treatment was investigated. Addition of sodium carbonate shows a protection against denaturation of myofibrillar proteins and provides a maximum water-holding capacity. Caustic marinades allowed a higher retention of product characteristics than low-pH marinades.

    Intensification of animal agriculture has profound impacts on the global and local biogeochemistry of nitrogen (N), resulting in consequences to environmental and human health. In the Chesapeake Bay watershed, intensive agriculture is the primary contributor to N pollution, with animal manure comprising more than half of N from agriculture. Management interventions may play an important role in mitigating reactive N pollution in the Bay watershed. The objective of our research was to test management strategies that maximize benefits of poultry manure as an agricultural resource while minimizing it as a source of reactive nitrogen to the atmosphere and ground and surface waters. We conducted field experiments in two agricultural regions of the Chesapeake Bay watershed (Georgetown, Delaware and State College, Pennsylvania) to explore the effects of poultry manure amendments on gaseous N losses and soil N transformations. Treatments were applied at rates needed to meet the plant N demand at each site and included unfertilized controls, fertilizer N (urea), and raw, composted, or and biocharred poultry manure. The fate of the N from all sources was followed throughout the growing season. Global greenhouse gases emitted from soil (nitrous oxide [N2O] and carbon dioxide [CO2]) and regional air pollutants (nitrogen oxides [NOx] and ammonia [NH3]) were measured. Gas measurements were coupled with data on treatment effects on temperature, moisture, and concentrations of nitrate (NO3¬-) and ammonium (NH4+) in surface soils (0-10 cm). Soil NO3- and NH4+ were also measured approximately monthly in the soil profile (0-10, 10-30, 30-50, 50-70, and 70-100 cm) as an index of leaching potential. Plant N uptake and grain production were also quantified to quantify crop N use efficiency and compare measured N losses for each N source. Our results suggest that the form of poultry manure amendments can affect the magnitude of reactive N losses to the environment.

    Full Text Available Poultry waste is an abundant renewable source for the recovery of several value-added metabolites with potential industrial applications. This study describes the production of protease on poultry waste, with the subsequent use of the same poultry waste for the extraction of antioxidants. An extracellular protease-producing strain was isolated from Cuddalore coast, India, and identified as Streptomyces sp. MAB18. Its protease was purified 17.13-fold with 21.62% yield with a specific activity of 2398.36 U/mg and the molecular weight was estimated as 43 kDa. The enzyme was optimally active at pH 8–10 and temperature 50–60°C and it was most stable up to pH 12 and 6–12% of NaCl concentration. The enzyme activity was reduced when treated with Hg2+, Pb2+, and SDS and stimulated by Fe2+, Mg2+, Triton X-100, DMSO (dimethyl sulfoxide, sodium sulphite, and β-mercaptoethanol. Furthermore, the antioxidant activities of protease were evaluated using in vitro antioxidant assays, such as DPPH radical-scavenging activity, O2 scavenging activity, NO scavenging activity, Fe2+ chelating activity, and reducing power. The enzyme showed important antioxidant potential with an IC50 value of 78±0.28 mg/mL. Results of the present study indicate that the poultry waste-derived protease may be useful as supplementary protein and antioxidant in the animal feed formulations.

    Full Text Available The ability of the influenza Orthomixovirus to undergo to continually antigenically changes that can affect its pathogenicity and its diffusion, explains the growing seriousness of this disease and the recent epizoozies in various parts of the world. There have been 15 HA and 9 NA type A sub-types of the influenza virus identified all of which are present in birds. Until now the very virulent avian influenza viruses identified were all included to the H5 and H7 sub-types. We here show that is possible to identify the H5 and H7 sub-types with reverse transcription-polymerase chain reaction (RT-PCR by using a set of specific primers for each HA sub-type. The RT-PCR is a quick and sensitive method of identifying the HA sub-types of the influenza virus directly from homogenised organs.

  19. Measuring the costs of biosecurity on poultry farms: a case study in broiler production in Finland

    2012-02-01

    Full Text Available Abstract Background Farm-level biosecurity provides the foundation for biosecurity along the entire production chain. Many risk management practices are constantly in place, regardless of whether there is a disease outbreak or not. Nonetheless, the farm-level costs of preventive biosecurity have rarely been assessed. We examined the costs incurred by preventive biosecurity for Finnish poultry farms. Methods We used a semi-structured phone interview and obtained results from 17 broiler producers and from 5 hatching egg producers, corresponding to about 10% of all producers in Finland. Results Our results indicate that the average cost of biosecurity is some 3.55 eurocent per bird for broiler producers (0.10 eurocent per bird per rearing day and 75.7 eurocent per bird for hatching egg producers (0.27 eurocent per bird per rearing day. For a batch of 75,000 broilers, the total cost would be €2,700. The total costs per bird are dependent on the annual number of birds: the higher the number of birds, the lower the cost per bird. This impact is primarily due to decreasing labour costs rather than direct monetary costs. Larger farms seem to utilise less labour per bird for biosecurity actions. There are also differences relating to the processor with which the producer is associated, as well as to the gender of the producer, with female producers investing more in biosecurity. Bird density was found to be positively related to the labour costs of biosecurity. This suggests that when the bird density is higher, greater labour resources need to be invested in their health and welfare and hence disease prevention. The use of coccidiostats as a preventive measure to control coccidiosis was found to have the largest cost variance between the producers, contributing to the direct costs. Conclusions The redesign of cost-sharing in animal diseases is currently ongoing in the European Union. Before we can assert how the risk should be shared or resort to the

    Poultry slaughterhouse sludge from chicken processing wastewater treatment plant was tested for their suitability as a substrate and inoculum source for fermentation hydrogen production. Dual digestion of poultry slaughterhouse sludge was employed to produce hydrogen by batch anaerobic self-fermentation without any extra-seeds. The sludge (5% TS) was dual digested by aerobic thermophilic digestion at 55 C with the varying retention time before using as substrate in anaerobic self-fermentation. The best digestion time for enriching hydrogen-producing seeds was 48 h as it completely repressed methanogenic activity and gave the maximum hydrogen yield of 136.9 mL H{sub 2}/g TS with a hydrogen production rate of 2.56 mL H{sub 2}/L/h. The hydrogen production of treated sludge at 48 h (136.9 mL H{sub 2}/g TS) was 15 times higher than that of the raw sludge (8.83 mL H{sub 2}/g TS). With this fermentation process, tCOD value in the activated sludge could be reduced up to 30%. (author)

    Full Text Available The objective of this study was to evaluate the efficiency of anaerobic digestion on the treatment of effluent from poultry slaughterhouse. The experiment was conducted at the Laboratory of Waste Recycling from Animal Production/FCA/UFGD. During four weeks, eight experimental digesters, semi-continuous models, were loaded and set according to the hydraulic retention time (HRT of 7, 14, 21 and 28 days, and according to the solid fraction treatment, separated with 1 mm sieve or without separation. The average weekly production of biogas and methane as well as the methane concentrations, the potential production per amount of chemical oxygen demand (COD added and reduced, the concentrations of N, P and K at the beginning and end of process, and the most likely numbers of total and thermotolerant coliforms were evaluated. For data analysis, a completely randomized design was performed in a 4 × 2 factorial arrangement (4 HRT: 7, 14, 21 and 28 days and separation with 1 mm sieve or without separation, with repetition over time. The highest production of biogas and methane was statistically significant for the HRT of 7 and 14 days (5.29 and 2.38 L of biogas and 4.28 and 1.73 L of methane, respectively. There was an interaction between HRT and the separation of the solid with sieve and the highest production was obtained in the treatment without separation. Similar behavior was observed for the potential production with a maximum of 0.41 m³ methane.kg-1 COD added with an HRT of 7 days without separation of the solid fraction. The separation of the solid fraction is not recommended in the pretreatment of liquid effluent from poultry slaughterhouse, once the potential for production and production of methane and biogas were reduced with this treatment.

    Full Text Available Mechanically deboning poultry meat (MDPM is widely used due to its suitable technological properties as well as low lipids and saturated fatty acids contents. Besides, production processes applied during the surimi production can improve the technological properties of MDPM. That is to say, the production steps of surimi can change chemical composition and concentration of myofibrillar proteins and improve functional properties of MDPM. In this study, MDPM was prepared from the poultry meat. The production process consisted of 2 washing steps with sodium bicarbonate solution followed by another washing step with 4°C water. Afterwards, chemical properties of MDPM and surimi (moisture content, protein, lipid, and ash content as well as electrophoresis pattern were evaluated. Result showed that surimi production steps could significantly decrease protein, lipid and ash contents; however, moisture content of MDPM increased significantly. The result of electrophoresis indicated a significant increase in heavy chain myosin with 200 KDa and actin with 45 KDa molecular weights. It was concluded that the production steps improved the chemical properties and increased the concentration of MDPM myofibrillar proteins.

    2007-09-01

    Full Text Available The amount of solid wastes generated in developing countries such as Nigeria has steadily increased over the last two decades as a result of population explosion and continuous growth of industries and agricultural practices. In agriculture, particularly cattle rearing, large quantities of cow wastes are generated, which could be used as biogas inputs to compliment the fuel usage alternative. In addition, a large number of families generate heavy wastes in the kitchen on a daily basis, which could be converted to economic benefits. In this work, a comparative study of biogas production from poultry droppings, cattle dung, and kitchen wastes was conducted under the same operating conditions. 3kg of each waste was mixed with 9L of water and loaded into the three waste reactors. Biogas production was measured for a period of 40 days and at an average temperature of 30.5oC. Biogas production started on the 7th day, and attained maximum value on the 14th days for reactor 1. Production reached its peak on the 14th day with 85´10-3dm3 of gas produced in reactor 2. For reactor 3, biogas production started on the 8th day and production reached a peak value on the 14th day. The average biogas production from poultry droppings, cow dung and kitchen waste was 0.0318dm3/day, 0.0230dm3/day and 0.0143dm3/day, respectively. It is concluded that the wastes can be managed through conversion into biogas, which is a source of income generation for the society.

    Full Text Available The study appraised the economic performance of small and medium scale poultry egg production in Ife and Ilesha metropolis, Osun State Nigeria. A purposive sampling was used to select one hundred and twenty poultry egg farmers, cluster sampling was used to select areas where small and medium scale were concentrated in the study area then sixty (60 small scale and sixty (60 medium scale were randomly selected to form the population of the study. Data were collected through structured interview schedule. Descriptive statistics such as means and percentages were employed for budgetary analysis and economic performance. The ordinary least square was used to determine the significant variables influencing the gross margin of poultry egg farmers at different levels of scale of production. The study shows that the gross margin of small farms was ₦575.65 while the gross margin of medium farms was ₦43672.62. The total production cost of small and medium farms were ₦1480.25 and ₦29654.43 respectively. The results further reveal that costs of feed constituted the largest share of the total costs for the two categories of farm size. The amount spent on drug and feed were the only significant determining factors of revenue accruable to both categories of poultry egg farmers. Although, poultry egg production was profitable in the study area, the level of profit depended on the scale of operation.

    Full Text Available Possibility of increase of efficiency of poultry manure application due to more evenness of fertilizer application into the soil was investigated. Machines with a wide range of regulation of an application rate, for example ROU-6 with interval from 4 to 80 t/ha are for this purpose necessary. Efficiency of poultry manure application for grain crops was increased due to using of machines of drum type with optimum doses fertilizing (12-16 t/ha. An assessment of efficiency was carried out. The drums rotation speed, shovel quantity and shape, their installation angle and a design of the directing board were determined. The developed modified working of a spreader of drum type allowed to reduce unevenness of width fertilizing by 12-14 percent, on length of unit pass - by 5 percent. It was established that if the dose increases more than 8 t/ha, the crop productivity growths not significant. At reduction of fertilizing unevenness from 97 to 72 percent yield losses decrease by 54.4 percent. At reduction of fertilizing unevenness more than 97 percent, efficiency worsens by 58 percent. Poultry manure spreading by the machine and tractor unit MTZ-82.1 + ROU-6M afforded an yield by 38 percent higher, in comparison with the machine and tractor unit T-150K + PRT-10. At decrease in unevenness from 82 to 43 percent of barley loss decreased by 29 percent. It was revealed that spreading by machine ROU-6M provided a yield increase by 8.6 percent more, than by machine PRT-10. Yield losses because of spreading unevenness made: by the PRT-10 operating - 30 percent; by the ROU-6M operating - 0.33 percent. The grain yield increase was higher thanks to more evenness of fertilizer application by ROU-6M with the new spreading working element.

    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

    2017-09-01

    Globalisation, climate change, changes in eating habits and the food industry, modern animal husbandry and market demands often have a negative impact on quality assurance, food safety and animal health. After the eradication of some zoonotic diseases that previously often jeopardized the human population, today in developed countries, the focus is mainly on the control of zoonoses transmitted by food. Salmonella is one of the most common pathogens that can be transmitted from animals to humans, and its reservoirs are poultry, cattle and pigs, so one transmission route to humans is from contaminated food of animal origin. Multidrug-resistant isolates of Salmonella, which can transfer their resistance genes to other microorganisms, are considered a serious threat to public health. Control of Salmonella primarily depends on a good monitoring system and knowledge of the presence of serovars and strains in an epizootiological area. During the first nine months of 2016, 1321 samples of poultry meat and products were examined, among which 108 harboured Salmonella. Altogether, 29 of the 108 isolates (26.85%) were Salmonella Infantis. For all 29 S. Infantis isolates, antimicrobial resistance was tested by the disc diffusion method. The isolates showed 100% resistance to amoxicillin, and nalidixic acid.

    By 2030, the global population will be 8.5 billion, placing pressure on international poultry production, of which China is a key producer 1 . From April 2017, China will implement the withdrawal of colistin as a growth promoter, removing over 8,000 tonnes per year from the Chinese farming sector 2 . To understand the impact of banning colistin and the epidemiology of multi-drug-resistant (MDR) Escherichia coli (using bla NDM and mcr-1 as marker genes), we sampled poultry, dogs, sewage, wild birds and flies. Here, we show that mcr-1, but not bla NDM , is prevalent in hatcheries, but bla NDM quickly contaminates flocks through dogs, flies and wild birds. We also screened samples directly for resistance genes to understand the true breadth and depth of the environmental and animal resistome. Direct sample testing for bla NDM and mcr-1 in hatcheries, commercial farms, a slaughterhouse and supermarkets revealed considerably higher levels of positive samples than the bla NDM - and mcr-1-positive E. coli, indicating a substantial segment of unseen resistome-a phenomenon we have termed the 'phantom resistome'. Whole-genome sequencing identified common bla NDM -positive E. coli shared among farms, flies, dogs and farmers, providing direct evidence of carbapenem-resistant E. coli transmission and environmental contamination.

    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

    A cross-sectional was conducted to establish the characteristics of rural poultry production in Nyandarua, Nakuru and Laikipia districts of Kenya. Sites of diverse agroecological zones (AEZ) in the 3 district were selected, thus Ol Kalou in Nyandarua, Njoro in Nakuru and Ng'arua in Laikipia. Each site was divided into 4 clusters according to AEZ and land size. Systematic sampling techniques were applied to select farmers. A checklist was then used to collect the baseline information for every household. The study revealed that the average flock size was 17.3 chicken with Ng'arua region demonstrating the largest flock size of 21 chickens. The purpose of rearing indigenous chicken were stated as home consumption and sale of eggs and meat, hatching eggs, and as gifts.Farmers in Ng'arua region reported the highest sale of eggs and chicken meat. the average number of broodings per year, number of eggs laid before a chicken becomes broody, eggs set for hatching and hatchability was 2.5, 16.5, 11.1 and 84.2%, respectively. The average chick mortality reported by farmers in te first eight weeks was 47.9%. Disease especially Newcastle, were cited as the main cause of mortality. Farmers did not commonly practice selection for genetic improvement, but occasionally they purchased a cock or hen to control inbreeding. In all the 3 regions, 78.4% of the respondents indicated that women took greater responsibility and decision making in the production of indigenous chicken; 54.8% of farmers used different herbs to treat and control diseases. Conventional vaccination,disinfection and deworming rarely practiced. On most farms, chickens were left to scavenge around the homestead, often they were supplemented with kitchen leftovers and a handful of grains. The survey results demonstrated that there was potential for improving rural poultry production through interventions using appropriate technologies that are currently on-shelf

    To detect the prevalence, the seasonal occurrence and distribution of Salmonella serotypes in poultry products and to determine the resistance profile of Salmonella isolates. A total of 96 skin-on chicken carcasses and 30 liver samples were analysed between May 2007 and May 2009 from twenty-two different commercial farm brands found in retail market countrywide. Salmonella was isolated from 38 (39·5%) of 96 chicken carcasses and from 10 (33·3%) of 30 liver samples. Higher isolation rate (60·4%) was observed in carcasses detected during summer (May to October), and lower isolation rate (18·7%) was observed in carcasses detected during winter (November to April); in liver samples, the positive rates were 53·4 and 13·2%, respectively. Twelve serotypes were detected with the serotypes Hadar, Enteritidis and Blockley being the most prevalent at 29·2, 22·9 and 12·5%, respectively. Nine of 11 Salm. Enteritidis isolates occurred during summer. Of 48 isolates, 38 (79%) were resistant to one or more of the antimicrobial agents used. The highest resistance rates were found to the following antimicrobials: streptomycin (64·5%), tetracycline (56·2%), nalidixic acid (39·5%), ampicillin and rifampicin (33·3%). The relatively high Salmonella spp. contamination rates of raw chicken meat and liver have been detected. Salm. Enteritidis isolates peaked in summer, increasing the risk to human health. Antibiotic resistance of Salmonella still remains a threat as resistance plasmids may be extensively shared between animal and humans. The study enabled us to improve the data on the seasonal occurrence of Salmonella and to determine the antimicrobial pattern profile and trends in Salmonella strains isolated from poultry retail products in Greece. © 2012 The Authors.

    2009-12-01

    A substantial number of studies has already investigated differences within the consumer market with regard to attitudes and perceptions in relation to farm animal welfare. Likewise, several studies focused on the gap that exists between positive attitudes and reported consumption or purchase intentions for sustainable food products in general and higher welfare products more specific, and on the factors influencing this attitude-behavior gap. Little or no studies, however, have started from reported pro-welfare behavior to distinguish between consumer groups and to explore the motivations of the respective behavior. With this study, we aim to group consumers according to their reported buying frequency of higher welfare eggs and higher welfare chicken meat. Similarities and dissimilarities between these groups are mapped in terms of individual characteristics, product attribute importance, perceived consumer effectiveness, perception of higher welfare products, and attitude toward a welfare label. The research methodology applied was a quantitative study with cross-sectional consumer survey data collected in Flanders in spring 2007 (n = 469). Pro-welfare behavior was unevenly distributed across different consumer segments, despite a general interest and concern for bird welfare. A consistent choice for standard (no welfare premium) poultry products was related to strong perceived price and availability barriers, to a low importance attached to ethical issues as product attributes, and to a low perceived consumer effectiveness. A consistent choice for products with higher welfare standards to the contrast associated with a high importance attached to ethical issues; a low effect of price and availability perception; a strong association of higher welfare products with product attributes like health, taste, and quality; and a high perceived consumer effectiveness. The identification of market segments with common characteristics is essential for positioning higher

    Feed used to rear farm animals for human consumption has often been implicated as vehicle for dissemination of microbial pathogens that can adversely affect both animals or birds, and humans. Radiation pasteurization of animal feed to improve its microbiological quality should reduce the incidence of feed-borne infection (both clinical and subs clinical) in the herd or flock. This would result in safer food for the consumer, and improved economic performance of the production unit. This latter benefit is particularly important because it could directly offset the treating the feed. The likelihood of occurrence, as well as the magnitude, of any improved economic performance in the herd or flock consuming the irradiated feed must be determined experimentally. Accordingly, short term feeding tests were carried out to determine the effect of radiation pasteurization of poultry feed on growth performance of young chicks. Newly hatched white leghorn cacklers were used in the present studies to examine the effects of (i) control vs irradiated feed; and (ii) control vs stressed (transient chilled) birds. Feed consumption and pen weight were monitored for 21 days. Three experiments were conducted in the summer of 1989, using separate lots of commercially obtained feed ingredients for each experiment, In two of the three feeding tests there was a highly significant (p<.01) increase in feed conversion efficiency in the birds fed the irradiated feed. The magnitude of the increased efficiency was 2.4% and 2.8% in the two positive experiments. In one of the two positive experiments the feed contained antibiotics (Penicillin and Streptomycin) while the feed in other was antibiotic-free these results suggest that radiation pasteurization of poultry feed may have a beneficial effect on the feed conversion efficiency of the birds consuming that feed.8 tab.

    Background Campylobacter is the most common cause of bacterial enteritis worldwide. Handling and eating of contaminated poultry meat has considered as one of the risk factors for human campylobacteriosis.Campylobacter contamination can occur at all stages of a poultry production cycle. The objective of this study was to determine the occurrence of Campylobacter during a complete turkey production cycle which lasts for 1,5 years of time. For detection of Campylobacter, a conventional culture method was compared with a PCR method. Campylobacter isolates from different types of samples have been identified to the species level by a multiplex PCR assay. Methods Samples (N = 456) were regularly collected from one turkey parent flock, the hatchery, six different commercial turkey farms and from 11 different stages at the slaughterhouse. For the detection of Campylobacter, a conventional culture and a PCR method were used. Campylobacter isolates (n = 143) were identified to species level by a multiplex PCR assay. Results No Campylobacter were detected in either the samples from the turkey parent flock or from hatchery samples using the culture method. PCR detected Campylobacter DNA in five faecal samples and one fluff and eggshell sample. Six flocks out of 12 commercial turkey flocks where found negative at the farm level but only two were negative at the slaughterhouse. Conclusion During the brooding period Campylobacter might have contact with the birds without spreading of the contamination within the flock. Contamination of working surfaces and equipment during slaughter of a Campylobacter positive turkey flock can persist and lead to possible contamination of negative flocks even after the end of the day's cleaning and desinfection. Reduction of contamination at farm by a high level of biosecurity control and hygiene may be one of the most efficient ways to reduce the amount of contaminated poultry meat in Finland. Due to the low numbers of Campylobacter in the

    Aflatoxins (AF) are toxic metabolites primarily produced by molds, Aspergillus flavus and Aspergillus parasiticus. Contamination of poultry feed with AF is a major concern to the poultry industry due to severe economic losses stemming from poor performance, reduced egg production, and diminished egg hatchability. This study investigated the inhibitory effect of 2 generally regarded as safe (GRAS), natural plant compounds, namely carvacrol (CR) and trans-cinnamaldehyde (TC), on A. flavus and A. parasiticus growth and AF production in potato dextrose broth (PDB) and in poultry feed. In broth culture, PDB supplemented with CR (0%, 0.02%, 0.04% and 0.08%) or TC (0%, 0.005%, 0.01% and 0.02%) was inoculated with A. flavus or A. parasiticus (6 log CFU/mL), and mold counts and AF production were determined on days 0, 1, 3, and 5. Similarly, 200 g portions of poultry feed supplemented with CR or TC (0%, 0.4%, 0.8%, and 1.0%) were inoculated with each mold, and their counts and AF concentrations in the feed were determined at 0, 1, 2, 3, 4, 8, and 12 weeks of storage. Moreover, the effect of CR and TC on the expression of AF synthesis genes in A. flavus and A. parasiticus (aflC, nor1, norA, and ver1) was determined using real-time quantitative PCR (RT-qPCR). All experiments had duplicate samples and were replicated 3 times. Results indicated that CR and TC reduced A. flavus and A. parasiticus growth and AF production in broth culture and chicken feed (P<0.05). All tested concentrations of CR and TC decreased AF production in broth culture and chicken feed by at least 60% when compared to controls (P<0.05). In addition, CR and TC down-regulated the expression of major genes associated with AF synthesis in the molds (P<0.05). Results suggest the potential use of CR and TC as feed additives to control AF contamination in poultry feed. © 2015 Poultry Science Association Inc.

    2002-01-01

    In order to identify the major disease conditions and factors limiting family chicken production in Coast and Dar-es-Salaam regions of Tanzania a survey was undertaken in six villages in two zones involving a total of 43 households. Field data were collected through identified farmer interviews in the wet and dry seasons of 1999/2000. During farm visits, the birds were clinically examined, sick and dead ones autopsied. Blood smears, serum and faecal samples were collected for laboratory examination. There was significant variation in the flock size and structure in the interviewed households. The 43 households kept 1099 chickens with an average of 25.5 per household in the wet season while in the dry season the numbers were 1352 and an average of 31.4. The ratio of chicks:growers: aduIts was 10:10:14 in the wet season and 11:10:10 in the dry season. The cock:hen ratio was 1:3.5. Average numbers of clutches per year ranged from 2.80-3.02 (average 2-94). The average number of eggs per clutch was 12 and consequently the number of eggs was 36 per hen/year. Hatchability was recorded to be 84.5. Chick mortality was found to be 30% and resulted mainly from diseases and predation. Out of 43 households interviewed, 23 kept their chickens in the chicken house, 12 within the family house, four in the kitchen/store, three kept their birds perched in trees and one used a woven basket. In all the households, scavenging was the system of feeding and sometimes supplemented by household scraps and other feeds. Poultry movement into the household's flocks resulting in mixing of birds from different flocks was rampant. Several diseases and in particular Newcastle disease were mentioned by farmers in both zones as the major constraints restricting rural chicken development. Other diseases included coughing/sneezing, fowl pox and parasitic diseases (helminths, external parasites, protozoa). Women played a major role in family poultry development through provision of labour, but men

    The paper presents nutritive value of broiler meat and table eggs, as these animal products are used for human nutrition on a daily basis. In the Republic of Croatia, average consumption of poultry meat amounts to 18.3 kg and to 160 eggs per capita.The most quality parts of broiler carcass are breasts and drumsticks with thighs. Breast muscles contain 21-23% protein, 1.90-1.97% fat, 75.28-76.01% water and 0.74-0.77% collagen. Thigh muscles contain 4.70-6.05% fat, 19.03-19.93% protein and 0.91-1.13% collagen. White meat contains more potassium and magnesium and less zinc and iron than dark meat. In 100 g of edible egg part there is 12.5-13.5 g protein, 10.7-11.6 g fat and 1.0-1.1 g minerals. Caloric valueof eggs is 167 Kcal. Eggs contain high amount of essential amino acids, especially leucine, isoleucine, lysine, arginine, valine and phenylalanine. Furthermore, eggs contain many vitamins, especially A, D, E, K and B-complex, as well as various macroelements and microelements. Eggs and meat enriched with one or more functional ingredients - nutricines (polyunsaturated fatty acids n-3), eicosapentaenoic acid, docosahexaenoic acid, selenium and lutein) meet the criteria of functional food because of their added value and benefits for human health.

    2017-12-01

    Full Text Available The technology for intensive broiler breeding using deep litter method provides convenient conditions for production of odour substances inside the barn. As a consequence, there are relatively high odour emissions in the breeding area and its surrounding, which has significant impacts on the life quality of both people and animals. The amount of produced emissions increases in time because it is closely related to the amount of poultry droppings accumulated in litter inside the barn. This paper deals with changes in odour intensity depending on time measured since the beginning of broiler fattening. Odour intensity was measured by methods of dynamic olfactometry. The estimated values gradually increased from 45 ouE·m-3 to the highest value of 259 ouE·m-3, which was determined in the final fattening phase (broilers’ age 33 days. The calculated odour substances emission values were in range from 0.02 ouE·s-1·bird-1 at the beginning of fattening up to 0.10 ouE·s-1·bird-1 in the final fattening phase. Odour emissions increased five times during the fattening period.

    Full Text Available Problems arising from conventional tillage (CT systems (such as soil erosion, decrease of organic matter, environmental damage etc. have led many farmers to the adoption of no-till (NT systems that are more effective in improving soil physical, chemical and microbial properties. Results from this study clearly indicated that NT, mulch tillage (MT, and winter rye cover cropping systems increased the activity of phosphatase, β-glucosidase and arylsulfatase at a 0–10 cm soil depth but decreased the activity of these enzymes at 10–20 cm. The increase in enzyme activity was a good indicator of intensive soil microbial activity in different soil management practices. Poultry litter (PL application under NT, MT, and rye cropping system could be considered as effective management practices due to the improvement in carbon (C content and the biochemical quality at the soil surface. The activities of the studied enzymes were highly correlated with soil total nitrogen (STN soil organic carbon (SOC at the 0–10 cm soil depth, except for acid phosphatase where no correlation was observed. This study revealed that agricultural practices such as tillage, PL, and cover crop cropping system have a noticeable positive effect on soil biochemical activities under cotton production.

    Chicken meat is frequently contaminated with Campylobacter jejuni and is thought to be the major source of organisms causing human Campylobacter enteritis. Genotypic similarities between Campylobacter isolates from chicken meat at retail outlets and patients with gastroenteritis in Barbados suggested that it is a vehicle for infection of humans on the island and prompted this investigation of transmission of Campylobacter in a local poultry operation. Campylobacter testing was conducted at the hatchery, on the broiler farm and in the processing plant for two consecutive production cycles. The genetic relatedness of Campylobacter isolates was determined by RAPD typing with primer OPA 11. Hatchery samples and week-old chicks were negative for Campylobacter. Flocks became colonized as early as three weeks after introduction to the farm. Ten distinct RAPD genotypes were identified among isolates. Some genotypes were similar and may be of clonal origin. There was no evidence of vertical transmission of Campylobacter. The results suggest that the broiler flock was infected from more than one source in the farm environment.

    The ability of Clostridium perfringens to germinate and grow in acidified ground beef as well as in 10 commercially prepared acidified beef, pork, and poultry products was assessed. The pH of ground beef was adjusted with organic vinegar to achieve various pH values between 5.0 and 5.6; the pH of the commercial products ranged from 4.74 to 6.35. Products were inoculated with a three-strain cocktail of C. perfringens spores to achieve ca. 2-log (low) or 4-log (high) inoculum levels, vacuum packaged, and cooled exponentially from 54.4 to 7.2°C for 6, 9, 12, 15, 18, or 21 h to simulate abusive cooling; the U.S. Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS) recommends a cooling time of 6.5 h. Total germinated C. perfringens populations were determined after plating on tryptose-sulfite-cycloserine agar and incubating the plates anaerobically at 37°C for 48 h. In addition, C. perfringens growth from spores was assessed at an isothermal temperature of 44°C. Growth from spores was inhibited in ground beef with a pH of 5.5 or below, even during extended cooling from 54.4 to 7.2°C in 21 h. In ground beef with a pH of 5.6, the growth was >1 log after 18 h of cooling from 54.4 to 7.2°C. However, 15 h of cooling controlled the growth to product with a pH ranging from 4.74 to 5.17, both during exponential abusive cooling periods of up to 21 h and during storage for 21 h at 44°C. While product cooled exponentially from 54.4 to 7.2°C in 15 h or less, the pH 6.35 product supported growth, even after 6 h of cooling from 54.4 to 7.2°C. These challenge tests demonstrate that adjustment of ground beef to pH of 5.5 or less and of barbeque products to pH of 5.63 or less inhibits C. perfringens spore germination and outgrowth during extended cooling periods from 54.4 to 7.2°C up to 15 h. Therefore, safe cooling periods for products with homogeneous, lower pHs can be substantially longer.

    Full Text Available In today’s world numerous logistics chains exist, competing for similar jobs in different markets throughout the world. By connecting the supply and demand, i.e. production and consumption, logistics chains create national, regional and global logistics network which task is to maximise total generated value. Generated valueis defined as the difference between the price of finished product or service and the input necessary to create such products. The chain profitability is shown by the difference between the income obtained through sale of products or services and total expenditure in that chain. Accordingly, this scientific debate researches the possibilityof production optimisation within logistic chain by application of dynamic programming method with emphasis on information technologies.

    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.

    Highlights: • Thermodynamic analysis and environmental impact assessment of H 2 production system. • Thermodynamic analysis identifies optimal conditions for H 2 production. • LCA is applied to evaluate the environmental impacts of H 2 production system. • Inventories data are derived from process simulation and from literature review. • Thermal energy process is the main contributor to the environmental impact. - Abstract: In this research, various assessment tools are applied to comprehensively investigate hydrogen production from steam reforming of poultry tallow (PT). These tools investigate the chemical reactions, design and simulate the entire hydrogen production process, study the energetic performance and perform an environment impact assessment using life cycle assessment (LCA) methodology. The chemical reaction investigation identifies thermodynamically optimal operating conditions at which PT may be converted to hydrogen via the steam reforming process. The synthesis gas composition was determined by simulations to minimize the Gibbs free energy using the Aspen Plus™ 10.2 software. These optimal conditions are, subsequently, used in the design and simulation of the entire PT-to-hydrogen process. LCA is applied to evaluate the environmental impacts of PT-to-hydrogen system. The system boundaries include rendering and reforming along with the required transportation process. The reforming inventories data are derived from process simulation in Aspen Plus™, whereas the rendering data are adapted from a literature review. The life cycle inventories data of PT-to-hydrogen are computationally implemented into SimaPro 7.3. A set of seven relevant environmental impact categories are evaluated: global warming, abiotic depletion, acidification, eutrophication, ozone layer depletion, photochemical oxidant formation, and cumulative non-renewable fossil and nuclear energy demand. The results are subject to a systematic sensitivity analysis and compared

  8. Enhancement of biogas production at the municipal wastewater treatment plant by co-digestion with poultry industry waste

    Budych-Gorzna, Magdalena; Smoczynski, Marcin; Oleskowicz-Popiel, Piotr

    2016-01-01

    Highlights: • Laboratory and full-scale trials on co-digestion of sludge and poultry waste were performed. • Successful scaling-up of the results from laboratory to full-scale was accomplished. • Incremental addition of poultry waste to the full-scale anaerobic digesters did not cause any inhibition of the process. • WWTP energy dependency can be reduced significantly by co-digestion of sludge and external source of waste. - Abstract: Municipal wastewater treatment plants (WWTPs) are energy-intensive and thus cost-intensive facilities; therefore, it is crucial to increase energy production directly at the WWTP. Enhancement of biogas production by addition of external substrates is one of the solutions to increase energy self-sufficiency of the WWTPs with an additional benefit of cutting down the greenhouse gas emission. The main aim of the work was to investigate full utilization of the capacity of full-scale digesters at the municipal WWTP by addition of poultry industry waste. At first, laboratory trials were conducted in order to identify the most suitable dose for co-digestion with primary and waste activated sludge and finally, based on the achieved laboratory results, full-scale trials were carried out directly at the municipal WWTP. Poultry industrial waste yielded between 0.39 and 0.88 m 3 of methane per kg of volatile solids during laboratory trials, depending on the added concentration. During full-scale investigation yield of 0.81 m 3 /kg VS was achieved. Enhanced biogas production improved WWTP energy self-sufficiency bringing closer to the aim of increasing the share of self-produced energy up to 80%.

    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.

    A study was undertaken to determine populations and profiles of yeast species on fresh and processed poultry products upon purchase from retail supermarkets and after storage at 5 degrees C until shelf life expiration, and to assess the potential role of these yeasts in product spoilage. Fifty samples representing 15 commercial raw, marinated, smoked, or roasted chicken and turkey products were analyzed. Yeast populations were determined by plating on dichloran rose bengal chloramphenicol (DRBC) agar and tryptone glucose yeast extract (TGY) agar. Proteolytic activity was determined using caseinate and gelatin agars and lipolytic activity was determined on plate count agar supplemented with tributyrin. Populations of aerobic microorganisms were also determined. Initial populations of yeasts (log10 cfu/g) ranged from less than 1 (detection limit) to 2.89, and increased by the expiration date to 0.37-5.06, indicating the presence of psychrotrophic species. Highest initial populations were detected in raw chicken breast, wings, and ground chicken, as well as in turkey necks and legs, whereas roasted chicken and turkey products contained less than 1 log10 cfu/g. During storage, yeast populations increased significantly (P chicken, ground chicken, liver, heart and gizzard, and in ground turkey and turkey sausage. Isolates (152 strains) of yeasts from poultry products consisted of 12 species. Yarrowia lipolytica and Candida zeylanoides were predominant, making up 39 and 26% of the isolates, respectively. Six different species of basidiomycetous yeasts representing 24% of the isolates were identified. Most Y. lipolytica strains showed strong proteolytic and lipolytic activities, whereas C. zeylanoides was weakly lipolytic. Results suggest that yeasts, particularly Y. lipolytica, may play a more prominent role than previously recognized in the spoilage of fresh and processed poultry stored at 5 degrees C.

    2011-12-01

    Full Text Available The aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (PBPM fed during late gestation on the performance, blood metabolites, and colostrum composition of Holstein dairy cows. Sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1 14% and 2 16% crude protein. The cow’s BCS was 3.56 ± 0.5 on average, at the beginning of the trial. Yields of milk, protein, lactose, fat, and SNF were not affected by prepartum dietary CP level. Colostrum composition (fat, CP and Total solids, blood metabolites (Ca, Glucose, Total protein, Albumin, Globulin and Urea N, and metabolic diseases incidence were not influenced by prepartum dietary CP level. There was no significant difference between treatments in body weight and BCS changes. As expected, blood urea N before calving was higher in the cows fed 16% CP diets. Serum cholesterol during prepartum and postpartum periods was significantly decreased as the CP increased in the diet. In general, although postpartum glucose level increased in cows which received 16% CP in the diet, it seems that no other obvious advantages over feeding the 14% CP diet are apparent. So feeding this last diet is recommended to close up cows.

    Full Text Available This study presents the results of an Italian investigation into the development of food quality for poultry meat in the organic sector, using the quality function deployment technique. The results show that among the characteristics of poultry, meat consumers assign greater importance to those that are strictly related to animal welfare issues. Price and product appearance (i.e., colour, presence of fat come in second. To meet these needs, producers can effectively operate along the supply chain by acting on poultry housing type, genotype lines, and stocking density. Information about these issues should then be shared with the consumers (i.e., clear product labelling.

    Food animal production systems have become more consolidated and integrated, producing large, concentrated animal populations and significant amounts of fecal waste. Increasing use of manure and litter as a more “natural” and affordable source of fertilizer may be contributing to contamination of fruits and vegetables with foodborne pathogens. In addition, human and animal manure have been identified as a significant source of antibiotic resistance genes thereby serving as a disseminator of resistance to soil and waterways. Therefore, identifying methods to remediate human and animal waste is critical in developing strategies to improve food safety and minimize the dissemination of antibiotic resistant bacteria. In this study, we sought to determine whether withdrawing antibiotic growth promoters or using alternatives to antibiotics would reduce the abundance of antibiotic resistance genes or prevalence of pathogens in poultry litter. Terminal restriction fragment length polymorphism (T-RFLP) paired with high throughput sequencing was used to evaluate the bacterial community composition of litter from broiler chickens that were treated with streptogramin growth-promoting antibiotics, probiotics, or prebiotics. The prevalence of resistance genes and pathogens was determined from sequencing results or PCR screens of litter community DNA. Streptogramin antibiotic usage did not elicit statistically significant differences in Shannon diversity indices or correlation coefficients among the flocks. However, T-RFLP revealed that there were inter-farm differences in the litter composition that was independent of antibiotic usage. The litter from all farms, regardless of antibiotic usage, contained streptogramin resistance genes (vatA, vatB, and vatE), macrolide-lincosamide-streptogramin B resistance genes (ermA and ermB), the tetracycline resistance gene tetM and class 1 integrons.

  8. PRODUCTION, MANAGEMENT AND THE ENVIRONMENT SYMPOSIUM: Measurement and mitigation of reactive nitrogen species from swine and poultry production.

    Science.gov (United States)

    Powers, W; Capelari, M

    2017-05-01

    Reactive nitrogen (Nr) species include oxides of nitrogen [N; nitric oxide, nitrogen dioxide and nitrous oxide (NO)], anions (nitrate and nitrite), and amine derivatives [ammonia (NH), ammonium salts and urea]. Of the different Nr species, air emissions from swine and poultry facilities are predominantly NH followed by NO. Excreta emissions are NH, ammonium ions, and urea with trace amounts of nitrate and nitrite. Farm systems and practices that handle manure as a wet product without pH modification favor almost exclusive NH production. Systems and practices associated with dry manure handling and bedded systems emit more NH than NO. Results from a turkey grow-out study estimated that just under 1% of consumed N was emitted as NO from housing, compared with just under 11% emitted as NH. Despite generally less NO emissions from animal housing compared with crop field emissions, NO emissions from housing are often greater than estimated. Lagoon systems emit more NO than either slurry or deep pit swine systems. Deep pit swine buildings emit only one-third the NO that is emitted from deep bedded swine systems. Laying hen, broiler chicken, and turkey buildings emit over 4 times as much NO as swine housing, on a weight-adjusted basis. Critical control points for mitigation center on: 1) reducing the amount of N excreted and, therefore, excreted N available for loss to air or water during housing, manure storage, or following land application of manures; 2) capturing excreted N to prevent release of N-containing compounds to air, water, or soil resources; or 3) conversion or treatment of N-containing compounds to non-reactive N gas.

    2015-07-01

    In order to predict the metabolisable energy content of ninety batches of cereal grains and cereal by-products for poultry, regression models derived from different sample aggregations and using chemical components as independent variables were compared. Several statistics have been calculated to estimate the error of prediction. The results indicate that the highest levels of significance and coefficients of determination were obtained for equations derived from the larger data sets. However, the lowest prediction errors were associated to equations calculated for data or groups of data closer to the ingredient studied. (Author)

    Full Text Available This study was conducted to evaluate the incidence of non-typhoidal Salmonella (NTS serotypes in raw and ready-to-eat (RTE broiler products in the North West Province of South Africa. A total of 120 raw broiler samples, 40 samples of polonies and 20 samples of smoked viennas were obtained from retail points in major cities and towns in the province. Samples were subjected to aerobic plate count and later screened for the presence of NTS using phenotypic and genotypic techniques. The average bacterial count in raw products was 3.1 x 105 cfu/g whereas bacterial contamination of RTE products was 1.8 x 103 cfu/g. The average recovery rate of NTS species from raw broiler products was 12.5% and the serotypes identified were S. typhimurium (46.4%, S. enteritidis (30.9% and S. newport (22.9%. No NTS was recovered from the RTE products. However, S. typhimurium was the predominant serotype in whole carcasses whereas S. enteritidis and S. newport were prevalent in chicken parts. Out of the 160 presumptive NTS isolates screened by polymerase chain reaction (PCR, 140 (87.5% were confirmed for the presence of the Salmonella-specific invA gene. In addition, 115 (82.4% of the confirmed isolates harboured the plasmid spvC gene. Random Amplified Polymorphic DNA (RAPD fingerprinting of isolates using RAPD 1 and RAPD 3 primers, revealed some inter- and intra-serotype genetic diversity among isolates, suggesting varying sources of contamination. The results of this study represent the first report on the incidence and prevalent serotypes of NTS in chicken products in the North West Province of South Africa.

    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 litter is a sub product of growth chicken, rich in nitrogen and used like fertilizer in grains and forage production. Normally is applied in the fields without treatment. It's a very good material to be used for biogas generation because his compounds are chicken manure, straw and others organics compounds like coffee and rice husks. The biogas produced by poultry litter can be used for electric generation or for the heating systems of chicken production. The aimed of this work was evaluated the biogas and methane production of poultry litter, chicken manure and wheat straw. The experiment was made in the Biogastechnikum Laboratory of Leibniz-Institut fuer Agrartechnik Potsdam-Bornim e.V. (ATB), in Potsdam-Germany, from May to December 2010, according the rule VDI 4630 (Verein Deutscher Ingenieure). According to set conditions of the experiment, the results for biogas production are 393.25, 398.37 e 518.44 Nl biogas/kg{sub TSadded} and methane 223.72, 229.68, e 272.73 Nlmethane/kg{sub TSadded}; for poultry litter, poultry manure and wheat straw, respectively.

    2007-10-01

    Full Text Available The inclusion of agricultural products with different nutritional features has altered the relationship, the upstream and the downstream of enterprises that produce and commercialize them. Coordination in the Agro Industrial System is demanded, including traceability as a way to guarantee the conformity of products, attending external clients and agricultural industries that require quality certification. This quality tool enables the identification of some details in the productive chain, such as seeds, farming, harvesting, storage, transportation and industrialization of products. Thus, this essay describes the concept of traceability and provides information of special products from a cooperative from Paraná, which has controlled process in the productive chain, demanded by contractual partnerships done with enterprises that provide fertilizers and food processors. It was identified that this cooperative commercializes three products that need traceability: two special kinds of corn and the regular kind of soybean.

    2007-01-01

    Optimization of biogas production from olive-mill wastewater (OMW) was attempted by codigesting with diluted poultry-manure (DPM) at mesophilic conditions. A series of laboratory experiments were performed in continuously-operating reactors, fed with mixtures of OMW and DPM at various concentrations. It was concluded that codigestion of OMW with DPM is possible without any dilution of OMW or addition of any chemicals. Biogas production was slightly higher when OMW was added to DPM up to a critical concentration (about 40%, expressed as contribution of OMW to the volatile solids of the mixture), after which production is decreased. The results were further verified by scaling up to a continuously-operating pilot-plant reactor digesting DPM, and confirmed that no negative impact was imposed by adding OMW up to the above critical value

    Migratory waterfowl are natural reservoirs for low pathogenic avian influenza viruses (AIVs) and may contribute to the long-distance dispersal of these pathogens as well as spillover into domestic bird populations. Surveillance for AIVs is critical to assessing risks for potential spread of these viruses among wild and domestic bird populations. The Delmarva Peninsula on the east coast of the United States is both a key convergence point for migratory Atlantic waterfowl populations and a region with high poultry production (>4,700 poultry meat facilities). Sampling of key migratory waterfowl species occurred at 20 locations throughout the Delmarva Peninsula in fall and winter of 2013–14. Samples were collected from 400 hunter-harvested or live-caught birds via cloacal and oropharyngeal swabs. Fourteen of the 400 (3.5%) birds sampled tested positive for the AIV matrix gene using real-time reverse transcriptase PCR, all from five dabbling duck species. Further characterization of the 14 viral isolates identified two hemagglutinin (H3 and H4) and four neuraminidase (N2, N6, N8, and N9) subtypes, which were consistent with isolates reported in the Influenza Research Database for this region. Three of 14 isolates contained multiple HA or NA subtypes. This study adds to the limited baseline information available for AIVs in migratory waterfowl populations on the Delmarva Peninsula, particularly prior to the highly pathogenic AIV A(H5N8) and A(H5N2) introductions to the United States in late 2014.

    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.

    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.

    Full Text Available Many people have led to the consumption of organic animal products in the event that the increase in sensitivity to a healthy diet in developed countries, and maintaining the safety of food of animal origin. 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.

    2013-12-01

    In the past few years, dairy industry has become one of the fastest growing sectors in the packaged food industry of Vietnam. However, the value-added creation among different activities in the value chain of Vietnam dairy sector is distributed unequally. In the production activities, the dairy farmers gain low value-added rate due to high input cost. Whereas the processing activities, which managed by big companies, generates high profitability and Vietnamese consumers seem to have few choices due to the lack of dairy companies in the market. These wicked problems caused an unsustainable development to the dairy value chain of Vietnam. This paper, therefore, will map and analyze the value chain of the dairy industry in Vietnam. It will also assess the value created in each activity in order to imply solutions for a sustainable development of Vietnam's dairy industry. M10, M11.

  5. Value Chain Structures that Define European Cellulosic Ethanol Production

    Directory of Open Access Journals (Sweden)

    Jay Sterling Gregg

    2017-01-01

    Full Text Available Production of cellulosic ethanol (CE has not yet reached the scale envisaged by the literature and industry. This study explores CE production in Europe to improve understanding of the motivations and barriers associated with this situation. To do this, we conduct a case study-based analysis of CE production plants across Europe from a global value chain (GVC perspective. We find that most CE production plants in the EU focus largely on intellectual property and are therefore only at the pilot or demonstration scale. Crescentino, the largest CE production facility in Europe, is also more interested in technology licensing than producing ethanol. Demonstration-scale plants tend to have a larger variety of feedstocks, whereas forestry-based plants have more diversity of outputs. As scale increases, the diversity of feedstocks and outputs diminishes, and firms struggle with feedstock provisioning, global petroleum markets and higher financial risks. We argue that, to increase CE production, policies should consider value chains, promote the wider bio-economy of products and focus on economies of scope. Whereas the EU and its member states have ethanol quotas and blending targets, a more effective policy would be to seek to reduce the risks involved in financing capital projects, secure feedstock provisioning and support a diversity of end products.

    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.

    2014-01-01

    Full Text Available The aim of this study was to evaluate the production and chemical composition of the essential oil of Brazilian pepper fruits grown in single and double rows using different doses of semi decomposed poultry litter in two evaluation times. The experiment was carried out at the Federal University of Grande Dourados, in the city of Dourados, state o- Mato Grosso do Sul, Brazil, from October 2009 to November 2010. Brazilian pepper plants were grown in single and double rows in soil with incorporated poultry litter at the doses of 0, 5, 10, 15 and 20 t ha-1. Treatments were arranged as a 2 x 5 factorial experiment in a randomized block design with four replications. Fruits were harvested 180 and 390 days after transplant (DAT. There was a significant interaction for fresh weight of fruits and weight of 50 fruits, being the values higher at 180 DAT in the double rows with increasing poultry litter doses. Fruits harvested 390 DAT showed higher diameter compared with those harvested 180 DAT. The number of fruits per bunch was significantly influenced by the doses of poultry litter, presenting a linear increase with increasing doses. The essential oil of the Brazilian pepper fruits obtained by hydrodistillation and analyzed by Gas chromatography - mass spectrometry exhibited predominance of monoterpenes, highlighting α-pinene (20.14% as the major constituent. The chemical composition of the essential oil was not influenced by the number of plant rows in the plot or by the doses of poultry litter in any evaluation time. Therefore, the cultivation of Brazilian pepper plants is recommended in double rows, with 13.59 t ha-1 of incorporated poultry litter in the soi, and with harvest of 180 DAT for higher fruit production.

  9. 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.

    Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in genetic diversity and population structure for at least one species, Eimeria tenella. The drivers associated with such distinct geographic variation are unclear, but may impact on the occurrence and extent of resistance to anticoccidial drugs and future subunit vaccines. India is one of the largest poultry producers in the world and includes a transition between E. tenella populations defined by high and low genetic diversity. The aim of this study was to identify risk factors associated with the prevalence of Eimeria species defined by high and low pathogenicity in northern and southern states of India, and seek to understand factors which vary between the regions as possible drivers for differential genetic variation. Faecal samples and data relating to farm characteristics and management were collected from 107 farms from northern India and 133 farms from southern India. Faecal samples were analysed using microscopy and PCR to identify Eimeria occurrence. Multiple correspondence analysis was applied to transform correlated putative risk factors into a smaller number of synthetic uncorrelated factors. Hierarchical cluster analysis was used to identify poultry farm typologies, revealing three distinct clusters in the studied regions. The association between clusters and presence of Eimeria species was assessed by logistic regression. The study found that large-scale broiler farms in the north were at greatest risk of harbouring any Eimeria species and a larger proportion of such farms were positive for E. necatrix, the most pathogenic species. Comparison revealed a more even distribution for E. tenella across production systems in south India, but with a lower overall occurrence. Such a polarised region- and

    Urban livestock keeping in developing cities have an important role in food security and livelihoods but can also pose a significant threat to the environment and health of urban dwellers. The aim of this study was to identify the different livestock systems in Nairobi, their supply chains, and their management and food safety risks. Seven focus group discussions with livestock production officers in charge of each major Nairobi sub-county were conducted. Data were collected on the type of systems existing for each livestock species and their supply chains, disease management, food safety risks, and general husbandry and gender factors. Supply chain flow diagrams and thematic analysis of the data was done. Results of the study show a large variability of livestock keeping in Nairobi. The majority were small scale with: Supply chain analysis indicated that most dairy farmers sold milk directly to consumers due to "lack of trust" of these in traders. Broiler and pig farmers sold mainly to traders but are dependent on few large dominating companies for their replacement or distribution of products. Selling directly to retailers or consumers (including own consumption), with backyard slaughtering, were important chains for small-scale pig, sheep and goat, and indigenous chicken keepers. Important disease risk practices identified were associated with consumption of dead and sick animals, with underground network of brokers operating for ruminant products. Qualified trained health managers were used mainly by dairy farmers, and large commercial poultry and pig farmers, while use of unqualified health managers or no treatment were common in small-scale farming. Control of urban livestock keepers was reported difficult due to their "feeling of being outlaws," "lack of trust" in government, "inaccessibility" in informal settlements, "lack of government funding," or "understaffing." Findings are useful for designing policies to help to control urban livestock production and

  13. Antimicrobial Susceptibility and Biofilm Production by Salmonella sp. Strains Isolated from Frozen Poultry Carcasses

    Directory of Open Access Journals (Sweden)

    MJ Sereno

    Full Text Available ABSTRACT The objectives of this study were to evaluate the antimicrobial resistance and the biofilm-producing ability of Salmonella sp. strains isolated from frozen poultry carcasses. Antimicrobial susceptibility was tested by the disk-diffusion method. Biofilm-producing ability was determined in 96-well polystyrene microplates stained with crystal violet at 1%. Out of the 22 strains tested, all were multiresistant, that is, resistant to more than three antimicrobial classes, and 72.7% were able to form biofilms. The highest resistance rates obtained were against sulfonamides, tetracycline, and quinolones. On the other hand, 100% of the strains were sensitive to chloramphenicol. According to the rate of biofilm formation, 3 (13.6% and 13 (59.1% strains were classified as moderate and weak biofilm-producers, respectively, and 27.3% did not form biofilms. Biofilms increase the tolerance of microorganisms to stress, reducing their sensitivity to disinfectants and antimicrobials; favor equipment corrosion; and act as substrates for the adhesion of bacteria with lower biofilm-producing capacity. The results of the present study stress the importance of cleaning procedures in food processing plants and highlight the public health risks related to the emergence of multiresistant strains.

    Dietary intake of phosphorus is derived largely from protein sources and is a critical determinant of phosphorus balance in patients with chronic kidney disease. Information about the phosphorus content of prepared foods generally is unavailable, but it is believed to contribute significantly to the phosphorus burden of patients with chronic kidney disease. Analysis of dietary components. We measured the phosphorus content of 44 food products, including 30 refrigerated or frozen precooked meat, poultry, and fish items, generally national brands. Measured and reported phosphorus content of foods. Phosphorus by using Association of Analytical Communities official method 984.27; protein by using Association of Analytical Communities official method 990.03. We found that the ratio of phosphorus to protein content in these items ranged from 6.1 to 21.5 mg of phosphorus per 1 g of protein. The mean ratio in the 19 food products with a label listing phosphorus as an additive was 14.6 mg/g compared with 9.0 mg/g in the 11 items without listed phosphorus. The phosphorus content of only 1 precooked food product was available in a widely used dietary database. Results cannot be extrapolated to other products. Manufacturers also may alter the phosphorus content of foods at any time. Protein content was not directly measured for all foods. Better reporting of phosphorus content of foods by manufacturers could result in improved dietary phosphorus control without risk of protein malnutrition.

    The influence of the increase of the organic loading rate (OLR) on methane production in a continuous stirred-tank reactor (CSTR) from physicochemical sludge generated in a poultry slaughterhouse was evaluated. Total solid (TS) to obtain OLR of 1, 5, 10 and 15 g VS L(-1) day(-1), with hydraulic retention times of 29, 6, 6 and 4, respectively, were conditioned. The results showed a decrease in pH levels and an increase in the theoretical volatile fatty acids (VFA). While the yield of methane production decreased from 0.48 to 0.10 LCH4/g VSremoved, respectively, the OLR-10 managed on average 38% removal of volatile solids (VS) and a yield biogas production of 0.81 Lbiogas g(-1) VSremoved and 1.35 L day(-1). This suggests that the OLR increases in an anaerobic system from physicochemical sludge only inhibits the methanogenic metabolism, because there is still substrate consumption and biogas production.

    2013-01-01

    Full Text Available The paper studied the process of product renewal in a supply chain, which is composed of one manufacturer and one retailer. There are original product and renewal product in the supply chain. A market share shift model for renewal product was firstly built on a increment function and a shift function. Based on the model, the decision-making plane consisting of two variables was divided into four areas. Since the process of product renewal was divided into two stages, Stackelberg-Nash game model and Stackelberg-merger game model could be built to describe this process. The optimal solutions of product pricing strategy of two games were obtained. The relationships between renewal rate, cost, pricing strategy, and profits were got by numerical simulation. Some insights were obtained from this paper. Higher renewal rate will make participants’ profits and total profit increase at the same margin cost. What is more important, the way of the optimal decision making of the SC was that RP comes onto the market with a great price differential between OP and RP.

    Industry 4.0 is the actual great step in industrial progress. Convergence of industrial equipment with the power of advanced computing and analysis, low-cost sensing, and new connecting technologies are presumed to bring unexpected advancements in automation, flexibility, and efficiency. In this context, sensors ensure information regarding three essential areas: the number of processed elements, the quality of production and the condition of tools and equipment. To obtain this valuable information, the data resulted from a sensor has to be firstly processed and afterward used by the different stakeholders. If machines are linked together, this information can be employed to organize the production chain with few or without human intervention. We describe here the implementation of a sensor in a milling machine that is part of a simple production chain, capable of providing information regarding the number of manufactured pieces. It is used by the other machines in the production chain, in order to define the type and number of pieces to be manufactured by them and/or to set optimal parameters for their working regime. Secondly, the information achieved by monitoring the machine and manufactured piece dynamic behavior is used to evaluate the product quality. This information is used to warn about the need of maintenance, being transmitted to the specialized department. It is also transmitted to the central unit, in order to reorganize the production by involving other machines or by reconsidering the manufacturing regime of the existing machines. A special attention is drawn on analyzing and classifying the signals acquired via optical sensor from simulated processes.

  6. Brazilian chicken meat production chain:a 10-year overview

    2015-03-01

    Full Text Available Brazil is the world's largest broiler meat exporter. Health control, knowledge and technology, as well as the natural aspects of the country are pointed out as the keys for the success of that product in the market. Brazilian broiler production grew significantly in the last decade; it creates jobs and has a significant social role in Brazilian economy. This study aimed at evaluating the Brazilian broiler meat supply chain from 2000 to 2010 using the social network analysis (SNA. Data from governmental and private sources were organized and analyzed. The focus of this study was the broiler production supply chain segment involving the hatchery, the broiler farm, the feed mill, the processing plant, and the government. The inputs considered were one-day-old chicks, pullet, feedstuff, and the infrastructure; and the outputs were broiler meat and taxes paid. The software UCINET was applied for calculating the structural attributes and indicators of the network. Results showed a relatively disorganized network in 2000 with the strongest tie between the farmer and the processing plant. The structural organization of the network improved until 2010. The density of the ties in the broiler meat production network increased steadily from 2000 to 2010 within a vertical cohesive supply chain structure. The success of Brazilian broiler meat production is attributed to the abundance of land, fertile soil, favorable climate, and the effort and investments in research and development by innovative companies in the last few years. The results of the present study showed that Brazilian broiler production evolved positively in the last ten years, and it was weakly influenced by international challenges.

  7. A profitable use of by-products of the poultry slaughter. The tanning of hen’s feet skins

    2013-01-01

    Full Text Available The aim of this development is to add value to one of the by-products of the poultry slaughtery, the chicken’s feet. The process began with the skinning of the chicken’s feet, which underwent a tanning process to obtain a leather characterised for its similarity with exotic leathers such as the reptile ones. To facilitate its possible production by artisanal means we designed a more environmental-friendly process, eliminating the use of sodium sulfide in the stages corresponding to dehairing and liming, followed by a chromium-free tanning based on a combination of vegetable tannins and synthetic retanning agents. Confirmation of the tanning of the skins was performed by measuring the shrinkage temperature of leathers, obtaining a value of 80 °C, higher than those of the raw hides. Physical properties were evaluated to characterize the product, obtaining tensile strength values of 0,65 kg/mm2 and a tear resistance of 2,10 kg/mm.

    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.

  12. Optimal matrix product states for the Heisenberg spin chain

    International Nuclear Information System (INIS)

    Latorre, Jose I; Pico, Vicent

    2009-01-01

    We present some exact results for the optimal matrix product state (MPS) approximation to the ground state of the infinite isotropic Heisenberg spin-1/2 chain. Our approach is based on the systematic use of Schmidt decompositions to reduce the problem of approximating for the ground state of a spin chain to an analytical minimization. This allows one to show that results of standard simulations, e.g. density matrix renormalization group and infinite time evolving block decimation, do correspond to the result obtained by this minimization strategy and, thus, both methods deliver optimal MPS with the same energy but, otherwise, different properties. We also find that translational and rotational symmetries cannot be maintained simultaneously by the MPS ansatz of minimum energy and present explicit constructions for each case. Furthermore, we analyze symmetry restoration and quantify it to uncover new scaling relations. The method we propose can be extended to any translational invariant Hamiltonian

    2014-03-01

    Full Text Available Global poultry production is plagued by a wide variety of arthropods. The problems associated with their chemical control have led to an increasing search for control alternatives, and entomopathogenic fungi seem to be a promising strategy. Despite the large number of insects and mites considered as important pests in animal production, studies on the use of entomopathogenic fungi for their control are still scarce compared with agricultural pests, particularly in Brazil. This article reviews some damages and control aspects of the main arthropod pests that affect Brazilian poultry production, including house flies, lesser mealworms, and feather mites, by the use of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae. Studies published in the last 20 years were reviewed, and the main problems and limitations of that pest-control strategy are discussed.

    Animal by-product rendering establishments are still relevant industries worldwide. Animal by-product meal safety is paramount to protect feed, animals, and the rest of the food chain from unwanted contamination. As microbiological contamination may arise from inadequate processing of slaughterhouse waste and deficiencies in good manufacturing practices within the rendering facilities, we conducted an overall establishment's inspection, including the product in several parts of the process.An evaluation of the Good Manufacturing Practices (GMP) was carried out, which included the location and access (i.e., admission) to the facilities, integrated pest management programs, physical condition of the facilities (e.g., infrastructure), equipments, vehicles and transportation, as well as critical control points (i.e., particle size and temperature set at 50 mm, 133°C at atmospheric pressure for 20 min, respectively) recommended by the OIE and the European Commission. The most sensitive points according to the evaluation are physical structure of the facilities (avg 42.2%), access to the facilities (avg 48.6%), and cleaning procedures (avg 51.4%).Also, indicator microorganisms (Salmonella spp., Clostridium spp., total coliforms, E. coli, E. coli O157:H7) were used to evaluate the safety in different parts of the animal meal production process. There was a prevalence of Salmonella spp. of 12.9, 14.3, and 33.3% in Meat and Bone Meal (MBM), poultry by-products, and fish meal, respectively. However, there were no significant differences (P = 0.73) in the prevalence between the different animal meals, according to the data collected.It was also observed that renderings associated with the poultry industry (i.e., 92.0%) obtained the best ratings overall, which reflects a satisfactory development of this sector and the integration of its production system as a whole.

  17. An overview on the Brazilian orange juice production chain

    2013-03-01

    Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

  18. Significant enhancement by biochar of caproate production via chain elongation.

    Science.gov (United States)

    Liu, Yuhao; He, Pinjing; Shao, Liming; Zhang, Hua; Lü, Fan

    2017-08-01

    In this study, biochar was introduced into a chain elongation system to enhance the bioproduction of caproate and caprylate. The concentration of caproate increased to 21.1 g/L upon the addition of biochar, which is the highest level of caproate reported for such a system to date when ethanol was used as electron donor. The addition of biochar created a tougher system with more stable microorganism community structure for chain elongation, in which no obvious inhibition by products or substrates was observed, moreover, the lag phase was reduced 2.3-fold compared to the system without biochar. These reinforcement effect of biochar are attributed to the enhanced conductivity due to the significant enrichment of functional microorganisms via the microbial network surrounding smaller biochar particles, and via the adsorption on the rough surfaces or pores of larger particles, which facilitated electron transfer. Higher amounts of extracellular polymer substances and higher conductivity induced by biochar could contribute to the reinforcement effect in chain elongation. Copyright © 2017 Elsevier Ltd.

    Food irradiation has developed during the last few years. Nevertheless this development would be larger if there was a recognized method to detect whether a foodstuff had been irradiated. BETTS et al. (1988) suggested a method based on the comparison of an aerobic plate count (APC) with a count obtained using the Direct Epifluorescence Filter Technique (DEFT). They showed that the APC of an irradiated product was considerably lower than that obtained by the DEFT; in this case the DEFT count gave an indication of the number of viable microbial population in the product before irradiation; the APC of a non irradiated product was very well correlated with the DEFT count. In the present work both methods were tested on deep frozen mechanically deboned chicken meat (MDCM) and fresh chicken meat. The fluorochrome used for the DEFT was acridine orange; the mesophilic microflora was counted on 'Plate Count Agar'. According to the results obtained with the deep frozen MDCM, aerobic plate counts and DEFT counts are very similar during 100 days of storage when the product has not been irradiated; if it has been irradiated the difference between the two counts is high (about two logarithmic units). With this method it is thus possible to detect an irradiated product and to know the number of viable microbial cells in the irradiated product before the treatment. The method was tested on fresh chicken meat stored at 4 deg C. At the beginning of the storage period, it is possible to detect irradiated products, but at the end the method fails. In the latter case, irradiation can be detected, but it would be impossible to say that a product had not been irradiated. This method is potentially applicable to deep frozen products, more than to fresh products

    Full Text Available The aims of this work were to establish improved conditions for lipase production by Candida viswanathii using agroindustrial wastes in solid-state cultivation and to purify and evaluate the application of this enzyme for poultry fat hydrolysis. Mixed wheat bran plus spent barley grain (1 : 1, w/w supplemented with 25.0% (w/w olive oil increased the lipase production to 322.4%, compared to the initial conditions. When olive oil was replaced by poultry fat, the highest lipase production found at 40% (w/w was 31.43 U/gds. By selecting, yeast extract supplementation (3.5%, w/w, cultivation temperature (30°C, and substrate moisture (40%, w/v, lipase production reached 157.33 U/gds. Lipase was purified by hydrophobic interaction chromatography, presenting a molecular weight of 18.5 kDa as determined by SDS-PAGE. The crude and purified enzyme showed optimum activity at pH 5.0 and 50°C and at pH 5.5 and 45°C, respectively. The estimated half-life at 50°C was of 23.5 h for crude lipase and 6.7 h at 40°C for purified lipase. Lipase presented high activity and stability in many organic solvents. Poultry fat hydrolysis was maximum at pH 4.0, reaching initial hydrolysis rate of 33.17 mmol/L/min. Thus, C. viswanathii lipase can be successfully produced by an economic and sustainable process and advantageously applied for poultry fat hydrolysis without an additional acidification step to recover the released fatty acids.

    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

    Antimicrobials are extensively used as growth promoters in animal feeds worldwide, but reliable estimates are lacking. We conducted an internet-based survey of commercial chicken and pig feed products officially approved for sale in Vietnam over the period March-June 2015. Information on the antimicrobial contents in feed products, alongside animal production data, was used to estimate in-feed antimicrobial consumption to produce one kilogram of live animal (chicken, pig), as well as to estimate country-wide antimicrobial consumption through animal feeds. A total of 1462 commercial feed formulations were examined. The survey-adjusted estimated antimicrobial contents were 25.7 and 62.3 mg/kg in chicken and pig feeds, respectively. Overall, it was estimated that 77.4 mg [95% CI 48.1-106.8] and 286.6 mg [95% CI 191.6-418.3] of in-feed antimicrobials were used to raise 1 kg of live chicken and pig, respectively. Bacitracin (15.5% feeds), chlortetracycline (11.4%), and enramycin (10.8%) were the most common antimicrobials present in chicken feed formulations, whereas bacitracin (24.8%), chlortetracycline (23.9%), and florfenicol (17.4%) were the most common in pig feed formulations. Overall, 57% of the total quantitative usage consisted of antimicrobials regarded by WHO of importance for human medicine, including amoxicillin, colistin, tetracyclines, neomycin, lincomycin, and bacitracin. These figures confirm a very high magnitude of in-feed consumption of antimicrobials, especially in pig production. Results from this study should encourage further monitoring of antimicrobials used in animal production, and foster discussion about existing policies on inclusion of antimicrobials in animal feed rations.

    The log mean numbers of aerobes, coliforms, Escherichia coli and presumptive staphylococci plus listerias on chicken carcasses and carcass portions at various stages of processing at a poultry packing plant were estimated from the numbers of those bacteria recovered from groups of 25 randomly selected product units. The fractions of listerias in the presumptive staphylococci plus listerias groups of organisms were also estimated. Samples were obtained from carcasses by excising a strip of skin measuring approximately 5 x 2 cm(2) from a randomly selected site on each selected carcass, or by rinsing each selected carcass portion. The log mean numbers of aerobes, coliforms, E. coli and presumptive staphylococci plus listerias on carcasses after scalding at 58 degrees C and plucking were about 4.4, 2.5, 2.2 and 1.4 log cfu/cm(2), respectively. The numbers of bacteria on eviscerated carcasses were similar. After the series of operations for removing the crop, lungs, kidneys and neck, the numbers of aerobes were about 1 log unit less than on eviscerated carcasses, but the numbers of the other bacteria were not substantially reduced. After cooling in water, the numbers of coliforms and E. coli were about 1 log unit less and the numbers of presumptive staphylococci plus listerias were about 0.5 log unit less than the numbers on dressed carcasses, but the numbers of aerobes were not reduced. The numbers of aerobes were 1 log unit more on boneless breasts, and 0.5 log units more on skin-on thighs and breasts that had been tumbled with brine than on cooled carcasses; and presumptive staphylococci plus listerias were 0.5 log unit more on thighs than on cooled carcasses. Otherwise the numbers of bacteria on the product were not substantially affected by processing. Listerias were 40% of the organisms were listerias.

    2015-01-01

    Plant secondary product glycosyltransferases belong to family 1 of the glycosyltransferase superfamily and mediate the transfer of a glycosyl residue from activated nucleotide sugars to lipophilic small molecules, thus affecting the solubility, stability and pharmacological activities of the sugar-accepting compounds. The biotechnological application of plant glycosyltransferases in glycoside synthesis has attracted attention because enzymatic glycosylation offers several advantages over chemical methods, including (1) avoiding the use of harsh conditions and toxic catalysts, (2) providing strict control of regio-and stereo-selectivity and (3) high efficiency. This review describes the in vivo and in vitro glycosylation of natural organic compounds using glycosyltransferases, focusing on our investigation of enzymatic synthesis of curcumin glycosides. Our current efforts toward functional characterization of some glycosyltransferases involved in the biosynthesis of iridoids and crocin, as well as in the sugar chain elongation of quercetin glucosides, are described. Finally, I describe the relationship of the structure of sugar chains and the intestinal absorption which was investigated using chemoenzymatically synthesized quercetin glycosides.

  3. Dependence of the product chain-length on detergents for long-chain E-polyprenyl diphosphate synthases

    2013-01-01

    Long-chain E-polyprenyl diphosphate synthases (E-PDS) catalyze repetitive addition of isopentenyl diphosphate (IPP) to the growing prenyl chain of an allylic diphosphate. The polyprenyl diphosphate products are required for the biosynthesis of ubiquinones and menaquinones required for electron transport during oxidative phosphorylation to generate ATP. In vitro, the long-chain PDSs require addition of phospholipids or detergents to the assay buffer to enhance product release and maintain efficient turnover. During preliminary assays of product chain-length with anionic, zwitterionic, and non-ionic detergents, we discovered considerable variability. Examination of a series of non-ionic PEG detergents with several long-chain E-PDSs from different organisms revealed that in vitro incubations with nonaethylene glycol monododecyl ether or Triton X-100 typically gave chain lengths that corresponded to those of the isoprenoid moieties in respiratory quinones synthesized in vivo. In contrast incubations in buffer with n-butanol, CHAPS, DMSO, n-octyl-β-glucopyranoside, or β-cyclodextrin or in buffer without detergent typically proceeded more slowly and gave a broad range of chain lengths.

    Patients with chronic kidney disease (CKD) are advised to limit their dietary intake of phosphorus and potassium as hyperphosphatemia and hyperkalemia are both associated with an increased risk of mortality. There is uncertainty concerning the actual content of these minerals in the Canadian food supply, as phosphorus and potassium are increasingly being used as food additives. This study aimed to determine the impact of food additives on the chemically analyzed content of phosphorus, potassium, sodium, and protein in commonly consumed meat, poultry, and fish products (MPFs). Foods representing commonly consumed MPF identified by a food frequency questionnaire in dialysis patients were purchased from three major grocery store chains in Canada. MPF with and without phosphorus and potassium additives listed on their ingredient list (n = 76) as well as reference MPF that was additive free (n = 15) were chemically analyzed for phosphorus, potassium, sodium, and protein content according to Association of Analytical Community official methods. Phosphorus, potassium, and sodium additives were present on the ingredient list in 37%, 9%, and 72% of MPF, respectively. Among MPF categories that contained a phosphorus additive, phosphorus content was significantly (P additives versus MPF without phosphorus additives and MPF reference foods (median [min, max]): (270 [140, 500] mg/100 g) versus (200 [130, 510] mg/100 g) versus (210 [100, 260] mg/100 g), respectively. Among MPF categories containing a potassium additive, foods listing a potassium additive had significantly more (P foods that did not list potassium additives and reference foods (900 [750, 1100] mg/100 g) versus (325 [260, 470] mg/100 g) versus (420 [270, 450] mg/100 g). The use of additives in packaged MPF products as indicated by the ingredient list can significantly contribute to the dietary phosphorus and potassium loads in patients with CKD. Patients with CKD should be educated to avoid MPF foods

  7. Torrefaction of residues and by-products from sunflower chain

    2013-09-01

    Full Text Available The high heterogeneity of some residual biomasses makes rather difficult their energy use and standardisation is a key aspect for these fuel products. Torrefaction is an interesting process used to improve the quality of ligno-cellulosic biomasses and to achieve standardisation. In the present study torrefaction has been employed on residues and by-products deriving from sunflower production chain, in particular sunflower stalks and oil press cake. The thermal behaviour of materials has been studied at first by thermo-gravimetric analysis in order to identify torrefaction temperatures range. Different residence time and torrefaction temperatures have been employed in a bench top torrefaction reactor afterwards. Analyses of raw and torrefied materials have been carried out to assess the influence of the process. As a consequence of torrefaction, the carbon and ash contents increase while the volatilisation range is reduced making the material more stable and standardised. Mass yield, energy yield and energy densification reach values of about 60 %, 80 % and 1.33 for sunflower stalks and 64 %, 85 % and 1.33 for sunflower oil press cake respectively. As highlighted by results, torrefaction is more interesting for sunflower stalks than oil cake and husks because of the different starting characteristics. Untreated oil cake and husks already show a good high heating value and the eventual torrefaction should be mild. On the contrary for sunflower stalks the process is more useful and could be more severe.

    Full Text Available Brazilian milk production has grown steadily and in 2004 the country became self-sufficient in dairy production. This article develops possible scenarios for the milk production chain in Brazil for the year 2020 in order to contribute to decisions that must be made by stakeholders. A literature review on foresight and the use of scenarios was conducted, and a scenario writing approach based on Wright and Spers (2006 was adopted, which includes the use of the Delphi method, Michael Porter's Five Competitive Forces model, Interpretative Structural Modeling (ISM (WRIGHT, 1991 and quantitative projections. This methodology provided four scenarios, with quantitative and qualitative elements: two exploratory scenarios ("milk, the new agribusiness star" and "a wasted future", a most probable scenario ("continuous but uneven growth" and a desired scenario ("competitive family agriculture". Overall, it is possible to note many market opportunities, as well as niche markets and the strengthening of cooperatives. Future prospects are also favorable to the dairy industry in general, but nearly all scenarios point to a concentration in the industrial sphere.

    2014-07-01

    The IAEA document 'Handbook of Parameter Values for the Prediction of Radionuclide Transfer in Terrestrial and Freshwater Environments' published in 2010 is one of the major sources of knowledge about the migration parameters of radionuclides in the agro-ecosystems that is necessary to assess the dose loads to the population. It is known from there that Sr and Cs transfer has been studied thoroughly, however the factors vary over a wide range. Few studies were conducted for Pu and Am transfer. It should be noted that the studies carried out in real conditions of radioactive contamination, i.e. under natural conditions is also very few. In this regard, since 2007 the territory of the former Semipalatinsk Test Site has been used for comprehensive radioecological studies, where the major radionuclides to be investigated are {sup 90}Sr, {sup 137}Cs, {sup 239+240}Pu, {sup 241}Am. The objects for these studies are birds and animals typical for the region, as well as products obtained from them (lamb, beef, horse meat, chicken, pork, cow's milk, mare's milk, eggs, chicken, chicken feathers, wool, leather). It should be noted that these products are the main agricultural goods that are available in these areas. The studies have been conducted with grazing animals in the most contaminated areas of the test site. Some groups of animals and birds were fed to contaminated feed, soil, contaminated water. Radionuclide intake by animal body with air were studied. Husbandry periods for animals and birds ranged from 1 to 150 days. The transfer parameters to cow and mare's milk have been investigated at single and prolonged intake of radionuclides, also their excretion dynamics has been studied. The studies revealed features of the radionuclide transfer into organs and tissues of animals and birds intaken with hay, water and soil. The results showed that the transfer factors vary up to one order. A relationship has been identified between distribution of

    Different optimization strategies applied to sequence of several stages of production chains were validated in this paper. Two benchmark problems described by ordinary differential equations (ODEs) were considered. A water tank and a passive CR-RC filter were used as the exemplary objects described by the first and the second order differential equations, respectively. Considered in the work optimization problems serve as the validators of strategies elaborated by the Authors. However, the main goal of research is selection of the best strategy for optimization of two real metallurgical processes which will be investigated in an on-going projects. The first problem will be the oxidizing roasting process of zinc sulphide concentrate where the sulphur from the input concentrate should be eliminated and the minimal concentration of sulphide sulphur in the roasted products has to be achieved. Second problem will be the lead refining process consisting of three stages: roasting to the oxide, oxide reduction to metal and the oxidizing refining. Strategies, which appear the most effective in considered benchmark problems will be candidates for optimization of the mentioned above industrial processes.

  15. Xanthophylls in Poultry Feeding

    Breithaupt, Diemar R.

    Since most consumers associate an intense colour of food with healthy animals and high food quality, xanthophylls are widely used as feed additives to generate products that meet consumers' demands. An important large-scale application is in poultry farming, where xanthophylls are added to feed to give the golden colour of egg yolk that is so much appreciated. Now, with numerous new applications in human food, in the pharmaceutical industry, and in cosmetic products, there is an increasing demand for xanthophylls on the international market (Volume 5, Chapter 4).

    Full Text Available Urban livestock keeping in developing cities have an important role in food security and livelihoods but can also pose a significant threat to the environment and health of urban dwellers. The aim of this study was to identify the different livestock systems in Nairobi, their supply chains, and their management and food safety risks. Seven focus group discussions with livestock production officers in charge of each major Nairobi sub-county were conducted. Data were collected on the type of systems existing for each livestock species and their supply chains, disease management, food safety risks, and general husbandry and gender factors. Supply chain flow diagrams and thematic analysis of the data was done. Results of the study show a large variability of livestock keeping in Nairobi. The majority were small scale with: <5 dairy cows, 1–6 dairy goats, <10 small ruminants, <20 pigs, 200–500 broilers, 300–500 layers, <10 indigenous chickens, or <20 rabbits. Beef keeping was mainly described as a “by the way” system or done by traders to fatten animals for 3 month. Supply chain analysis indicated that most dairy farmers sold milk directly to consumers due to “lack of trust” of these in traders. Broiler and pig farmers sold mainly to traders but are dependent on few large dominating companies for their replacement or distribution of products. Selling directly to retailers or consumers (including own consumption, with backyard slaughtering, were important chains for small-scale pig, sheep and goat, and indigenous chicken keepers. Important disease risk practices identified were associated with consumption of dead and sick animals, with underground network of brokers operating for ruminant products. Qualified trained health managers were used mainly by dairy farmers, and large commercial poultry and pig farmers, while use of unqualified health managers or no treatment were common in small-scale farming.

    2015-04-01

    Full Text Available Biosurfactants are valuable microbial amphiphilic molecules with effective surface-active and biological properties applicable to several industries and processes. Microorganisms synthesize them, especially during growth on water-immiscible substrates, providing an alternative to chemically prepared conventional surfactants. Microbial surfactants are not yet a sustainable alternative to chemically synthesized surfactants seeing their potentially high production charges. This study highlights the use of low-cost agro-industrial raw material for fermentative production of biosurfactants. The Box–Behnken Design and response surface methodology were employed to optimize the concentrations of the ratio butter milk /distilled water, poultry-transforming wastes and inoculum size for lipopeptide biosurfactant production by B.subtilis SPB1 in submerged fermentation.The best production yield was about 12.61 ± 0.7 g/L of crude lipopeptide biosurfactant. It can be obtained when using a ratio butter milk /distilled water of 1.5, poultry-transforming wastes of 23g/L and an inoculum size of 0.12. In comparison to the highest biosurfactant production yield reported for Bacillus subtilis SPB1, three fold increases were obtained.

    2013-01-01

    Full Text Available The worldwide prevalence of multiple resistant Salmonella spp is described. Clonally distributed Salmonella Enteritidis PT4 and Salmonella Typhimurium DT104 are among the most pathogenic strains for humans. Recently there have been reports on the prevalence of ST “like” monophasic 4(5,12:i strains in some countries. Vaccination strategy and antimicorbial agent therapy is also briefly discussed. Products of animal origin must be safe and without the risk of antimicrobial resistance. Subsequently, the good management practice at farm level and HACCP in feed factories are required to cope with salmonella infections. Poultry producers in developed countries have been motivated to participate in salmonella control programs, because of public awareness on safe food and risks in the food chain. Export of poultry and poultry products is more successful in the regions where Salmonella Enteritidis and Salmonella Typhimurium have been eradicated.

    More energy-efficient, durable, affordable, and dimmable light-emitting diode (LED) lights are finding applications in poultry production. However, data are lacking on controlled comparative studies concerning the impact of such lights during the pullet rearing and subsequent laying phase. This study evaluated two types of poultry-specific LED light (PS-LED) vs. fluorescent light (FL) with regards to their effects on hen laying performance. A total of 432 Hy-Line W-36 laying hens were tested in two batches using four environmental chambers (nine cages per chamber and 6 birds per cage) from 17 to 41 weeks of age (WOA). Dim-to-red PS-LED and warm-white FL were used in the laying phase. The hens had been reared under a dim-to-blue PS-LED or a warm-white FL from 1 to 16 WOA. The measured performance variables included 1) timing of sexual maturity, 2) egg production performance, 3) egg quality, and 4) egg yolk cholesterol. Results showed that the two types of light used during the laying phase had comparable performance responses for all response parameters (P > 0.05) with a few exceptions. Specifically, eggs laid from hens in the PS-LED treatment had lower shell thickness (P = 0.01) and strength (P = 0.03) than those in the FL treatment at 41 WOA. The two types of light used during the rearing phase did not influence the 17 to 41 WOA laying performance, except that hens reared under the PS-LED laid eggs with lower shell thickness (P = 0.02) at 32 WOA as compared to hens reared under the FL. This study demonstrates that the emerging poultry-specific LED lights yield comparable production performance and egg quality of W-36 laying hens to the traditional fluorescent lights.

    Interspecies transmission of pathogens is an unfrequent but naturally occurring event and human activities may favour opportunities not previously reported. Reassortment of zoonotic pathogens like influenza A virus can result from these activities. Recently, swine and birds have played a central role as "mixing vessels" for epidemic and pandemic events related to strains like H1N1 and H5N1. Unsafe practices in poultry markets and swine farms can lead to interspecies transmission, favouring the emergence of novel strains. Thus, understanding practices that lead to interspecies interactions is crucial. This qualitative study aimed to evaluate poultry processing practices in formal and informal markets and the use of leftovers by swine farmers in three Peruvian cities: Lima (capital), Tumbes (coastal) and Tarapoto (jungle). We conducted 80 direct observations at formal and informal markets and interviewed 15 swine farmers. Processors slaughter and pluck chickens and vendors and/or processors eviscerate chickens. Food safety and hygiene practices were suboptimal or absent, although some heterogeneity was observed between cities and chicken vendors versus processors. Both vendors (76%) and processors (100%) sold the chicken viscera leftovers to swine farmers, representing the main source of chicken viscera for swine farms (53%). Swine farmers fed the chicken viscera to their swine. Chicken viscera cooking times varied widely and were insufficient in some cases. Non-abattoired poultry leads to the sale of poultry leftovers to small-scale swine farms, resulting in indirect but frequent interspecies contacts that can lead to interspecies transmission of bacterial pathogens or the reassortment of influenza A viruses. These interactions are exacerbated by suboptimal safety and hygiene conditions. People involved in these activities constitute an at-risk population who could play a central role in preventing the transmission of pathogens between species. Educational

  8. Ionizing energy treatment of poultry

    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

  9. Simulations at Czech poultry market

    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.

    Full Text Available Traditional wholesale and retail, electricity supplier of agricultural products supply chain have many difficulties. The O2O supply chain of agricultural products of “Internet+”, committed to the integration of online and offline advantage process, has become the main direction of the agricultural products supply chain transformation. Practice operation results show that O2O supply chain can effectively play the advantages of online and offline process integration, but its further development is still subject to the logistics, information flow of the dispersion, fracture and high cost. The integrated optimization of various regions and various enterprises and all sectors of the supply chain process is the key to optimize the process Internet plus era of agricultural products supply chain.

  11. Evaluation and selection of Bacillus species based on enzyme production, antimicrobial activity and biofilm synthesis as direct-fed microbials candidates for poultry

    2016-10-01

    Full Text Available Social concern about misuse of antibiotics as growth promoters (AGP and generation of multidrug-resistant bacteria have restricted the dietary inclusion of antibiotics in livestock feed in several countries. Direct-fed microbials (DFM are one of the multiple alternatives commonly evaluated as substitutes of AGP. Sporeformer bacteria from the genus Bacillus have been extensively investigated because of their extraordinary properties to form highly-resistant endospores, production of antimicrobial compounds and synthesize different exogenous enzymes. The purpose of the present study was to evaluate and select Bacillus spp. from environmental and poultry sources as DFM candidates, considering their enzyme production profile, biofilm synthesis capacity and pathogen-inhibition activity. Thirty one Bacillus isolates were screened for in vitro relative enzyme activity of amylase, protease, lipase and phytase using a selective media for each enzyme, with 3/31 strains selected as superior enzyme producers. These three isolates were identified as B. subtilis (1/3, and B. amyloliquefaciens (2/3 based on biochemical tests and 16S rRNA sequence analysis. For evaluation of biofilm synthesis, the generation of an adherent crystal violet-stained ring was determined in polypropylene tubes, resulting in 11/31 strains showing a strong biofilm formation. Moreover, all Bacillus strains were evaluated for growth inhibition activity against Salmonella enterica serovar Enteritidis (26/31, Escherichia coli (28/31 and Clostridioides difficile (29/31. Additionally, in previous in vitro and in vivo studies, these selected Bacillus strains have shown to be resistant to different biochemical conditions of the gastrointestinal tract of poultry. Results of the present study suggest that the selection and consumption of Bacillus-DFM, producing a variable set of enzymes and antimicrobial compounds may contribute to enhanced performance through improving nutrient digestibility

  13. The value of supply chain coordination under moral hazard: A case study of the consumer product supply chain

    Lee, Yumi; Song, Sang Hwa

    2018-01-01

    In this paper, we examine a real-world case related to the consumer product supply chain to analyze the value of supply chain coordination under the condition of moral hazard. Because of the characteristics of a buyback contract scheme employed in the supply chain, the supplier company’s sales department encourages retailers to order more inventory to meet their sales target, whereas retailers pay less attention to their inventory level and leftovers at the end of the season. This condition induces moral hazard problems in the operation of the supply chain, as suppliers suffer from huge returns of leftover inventory. This, in turn, is related to the obsolescence of returned inventory, even with penalty terms in the contract for the return of any leftovers. In this study, we show under the current buyback-based supply chain operation, the inventory levels of both the supplier and retailers exceed customer demand and develop vendor-managed inventory (VMI) system with base stock policy to remove any mismatch of supply and demand. A comparison of both systems shows that through the proper coordination of supply chain operations, both suppliers and retailers can gain additional benefits while providing proper services to end customers.

    2013-03-01

    Many different drivers, including productivity, ecosystem size, and disturbance, have been considered to explain natural variation in the length of food chains. Much remains unknown about the role of these various drivers in determining food chain length, and particularly about the mechanisms by which they may operate in terrestrial ecosystems, which have quite different ecological constraints than aquatic environments, where most food chain length studies have been thus far conducted. In this study, we tested the relative importance of ecosystem size and productivity in influencing food chain length in a terrestrial setting. We determined that (1) there is no effect of ecosystem size or productive space on food chain length; (2) rather, food chain length increases strongly and linearly with productivity; and (3) the observed changes in food chain length are likely achieved through a combination of changes in predator size, predator behavior, and consumer diversity along gradients in productivity. These results lend new insight into the mechanisms by which productivity can drive changes in food chain length, point to potential for systematic differences in the drivers of food web structure between terrestrial and aquatic systems, and challenge us to consider how ecological context may control the drivers that shape food chain length.

  6. Greenhouse gas emissions in milk and dairy product chains: Improving the carbon footprint of dairy products

    Energy Technology Data Exchange (ETDEWEB)

    Flysjoe, A.M.

    2012-11-01

    The present PhD project has focused on some of the most critical methodological aspects influencing GHG emission estimates of milk and dairy products and how the methodology can be improved. In addition, the Carbon Footprint (CF) for different types of dairy products has been analysed. Based on these results, mitigation options have been identified along the entire dairy value chain. The key methodological challenges analysed in the present study are: estimation of CH{sub 4} and N{sub 2}O emissions, assessment of CO{sub 2} emissions from land use change (LUC), co-product handling, and definition of the functional unit. Estimates of the biogenic emissions CH{sub 4} and N{sub 2}O are associated with large uncertainties due to the complexity and natural variation in biological processes. Accounting for these variations resulted in a {+-}30-50% variation in the CF for milk in Sweden and New Zealand (excluding emissions from LUC). The inclusion of emissions from LUC can drastically affect the CF of dairy products, and different models can even provide contradictory results. Thus, it is suggested that emissions associated with LUC are reported separately and that underlying assumptions are clearly explained. Accounting for the by-product beef is decisive for the CF of milk, and when designing future strategies for the dairy sector, milk and meat production needs to be addressed in an integrated approach. It is shown that an increase in milk yield per cow does not necessarily result in a lower CF of milk, when taking into account the alternative production of the by-product beef. This demonstrates that it is important to investigate interactions between different product chains, i.e. to apply system thinking. The CF of dairy products from Arla Foods analysed in the present study range from: 1.2-5.5 kg CO{sub 2}e per kg fresh dairy products, 7.3-10.9 kg CO{sub 2}e per kg butter and butter blends, 4.5-9.9 kg CO{sub 2}e per kg cheese, and 1.0-17.4 kg CO{sub 2}e per kg milk

The CF of dairy products from Arla Foods analysed in the present study range from: 1.2-5.5 kg CO{sub 2}e per kg fresh dairy products, 7.3-10.9 kg CO{sub 2}e per kg butter and butter blends, 4.5-9.9 kg CO{sub 2}e per kg cheese, and 1.0-17.4 kg CO{sub 2}e per kg milk

  10. Microbiological quality of poultry meat: a review

    Directory of Open Access Journals (Sweden)

    GC Mead

    2004-09-01

    Full Text Available Poultry meat can be contaminated with a variety of microorganisms, including those capable of spoiling the product during chill storage, and certain foodborne pathogens. Human illness may follow from handling of raw meat, undercooking or mishandling of the cooked product. While Salmonella and Campylobacter spp. remain the organisms of greatest global concern in this respect, others present include the more recently reported Arcobacter and Helicobacter spp. and, occasionally, verotoxigenic Escherichia coli. Also considered here is the growing problem of antimicrobial resistance among poultry-associated pathogens. Because of the need for a systematic and universally applicable approach to food safety control, the Hazard Analysis Critical Control Point (HACCP concept is increasingly being introduced into the Poultry Industry, and Quantitative Risk Assessment (QRA is being applied to microbial hazards. Among a number of completed and on-going studies on QRA are those undertaken by FAO/WHO on Salmonella and Campylobacter in broilers. In the case of Campylobacter, however, any QRA must assume at present that all strains have the same pathogenic potential for humans and comparable survival capabilities, even though this is unlikely to be the case. Implementation of the HACCP system in poultry processing plants addresses zoonotic agents that are not detectable by conventional meat inspection procedures and can help to control contamination of carcasses with spoilage organisms. The system brings obvious benefits in optimising plant hygiene, ensuring compliance with legislation and providing evidence of 'due diligence' on the part of the processor. It is now being applied globally in two different situations: in one, such as that occurring in the USA, carcass contamination is clearly reduced as carcasses pass through the process and are finally chilled in super-chlorinated water. There is also the option to use a chemical-rinse treatment for further

  11. CONDOS-II, Radiation Dose from Consumer Product Distribution Chain

    International Nuclear Information System (INIS)

    1984-01-01

    1 - Description of problem or function: This code was developed under sponsorship of the Nuclear Regulatory Commission to serve as a tool for assessing radiation doses that may be associated with consumer products that contain radionuclides. The code calculates radiation dose equivalents resulting from user-supplied scenarios of exposures to radionuclides contained in or released from sources that contain radionuclides. Dose equivalents may be calculated to total body, skin surface, skeletal bone, testes, ovaries, liver, kidneys, lungs, and maximally exposed segments of the gastrointestinal tract from exposures via (1) direct, external irradiation by photons (including Bremsstrahlung) emitted from the source, (2) external irradiation by photons during immersion in air containing photon-emitting radionuclides that have escaped from the source, (3) internal exposures by all radiations emitted by inhaled radionuclides that have escaped from the source, and (4) internal exposures by all radiations emitted by ingested radionuclides that have escaped from the source. 2 - Method of solution: Organ dose equivalents are approximated in two ways, depending on the exposure type. For external exposures, energy specific organ-to-skin-surface dose conversion ratios are used to approximate dose equivalents to specific organs from doses calculated to a point on the skin surface. The organ-to-skin ratios are incorporated in organ- and nuclide-specific dose rate factors, which are used to approximate doses during immersion in contaminated air. For internal exposures, 50 year dose equivalents are calculated using organ- and nuclide-specific, 50 year dose conversion factors. Doses from direct, external exposures are calculated using the energy-specific dose conversion ratios, user supplied exposure conditions, and photon flux approximations for eleven source geometries. Available source geometries include: point, shielded and unshielded; line, shielded and unshielded; disk, shielded

  12. Commercialization channels of organic products in Brazil: analysis at the first level of the production chain

    2017-10-01

    Full Text Available Abstract Specialized literature on organic production highlights the presence and concentration of retail, especially supermarkets, in the organic enhancement chain. This presents enormous obstacles for the entrance of small farmers in the production of organic products due to administrative barriers, in addition to pressure for lower prices by the supermarket retail network. This paper investigates the commercialization channels of organic production in Brazil. The survey was undertaken in 2013; questionnaires were sent to 900 out of approximately 11.200 farmers producing organic products; 216 answers were received. Analysis showed that approximately 90% of farmers provided for the internal market and 60% of the products were fresh fruits and vegetables. The distribution of organic products in Brazil is highly fragmented at the local, regional and national levels. The presence of supermarkets and intermediaries in the commercialization of fruits and vegetables is relevant, regardless of the size of the farm. There is a great dispersion of channels in the case of small farmers, although supermarkets rank second. However, direct commercialization (farmers markets is the main form of commercialization of the produce. Commercialization triggered by social programs has guaranteed a considerable part of the income on small production units or small farms. It seems that high involvement of retail networks and agents in the agribusiness segment causes low development rates in small agricultural units and in local development due to the latter’s low profit margins.

    Full Text Available Based on the fact that the current fresh agricultural products are susceptible to natural risks and the coordination of supply chain is poor, This paper constructs the supply chain profit model under the two models of natural risk and agricultural insurance, Firstly, studying the coordination function of the supply chain system under Two-part Tariff; Then discussing the setting and claiming mechanism of agricultural insurance, compares the influence of agricultural insurance on supply chain profit and supply chain coordination; Finally, giving an example to validate the model results and give decision - making opinions. Research shows that the supply chain of fresh agricultural products can coordinated under Two-part Tariff, but the supply chain cooperation is poor in the natural risk , need to further stabilize and optimize the supply chain; When the risk factor is less than the non-participation insurance coefficient, not to participate in agricultural insurance is conducive to maintaining the coordination of the supply chain system; When the risk coefficient exceeds the non-participation insurance coefficient, the introduction of agricultural insurance can not only effectively manage the natural risks, but also help to improve the coordination of the supply chain system.

    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

    1995-12-31

    A framework is presented for the analysis of economic and environmental impacts of policies applied to materials-product (MP) chains. This is based on material flows, product flows, costs, prices and optimal management of an MP chain. The main difference with other studies focusing on materials flows is that in this study the link between products of services and materials is explicitly dealt with. The framework is developed on the basis of materials balance conditions, production functions allowing for substitution, and recycling of both materials and products. After presenting theoretical MP chain-models and analytical results, an application to the problem of choosing between zinc and PVC gutters is discussed. Here optimal MP chain management decisions are presented for various policy and strategy scenarios. 3 figs., 5 tabs., 12 refs., 3 appendices

    Full Text Available The total quality principles implementation contributes to the improving in meeting the consumer needs, essential reduction of costs and increasing sales. The total quality is a concept that assures the total satisfaction of clients on the entire distribution chain, including all the actors in this chain. The aquaculture and fisheries are very diverse sectors which use different breeding and fishing technologies and provide a wide variety of specific products. This induces a real complexity of the supply and distribution chain for fish and fishery products, including the links from the production point (fishery or farm to the final consumer. The components of the distribution chain differ with the geographic areas, type of farms, transportation, information on the fishery market and management systems. Implementing the total food quality system for fishery products involves the quality specification in all marketing stages for all products, along the entire distribution chain. The present work was focused on identifying the distribution chain for fish and fishery products with the identification of the specificity of this type of chain form farm to end consumer, which is the first step in the implementation of total quality concept in aquaculture, with all the benefits that come with it.

    Full Text Available Abstract Chickens deaminate excess amino acids and excrete the derived nitrogen in the urine mainly as uric acid which is readily converted to ammonia. This gas has adverse effects on the health of chickens and air quality. Production of ammonia and its effect on the growth of chickens was monitored at a poultry house of House Number 5743 Mukuba Road in Riverside Kitwe from 21st August 2013 to 6th June 2014. Two batches of fifty day old hybrid broiler chicks were bred in house A and B 5 m x 7 m under the same management system in three phases. House A chicks were fed on Novatek feed only while those in house B were fed on Novatek feed blended with 0.5 0.7 and 0.9 ww bamboo charcoal of amp8804600m particle size. Weekly mass recording by the use of a weighing scale provided a measure of growth rate while analysis of the excreta using Kjeldahl method at the Copperbelt University and Nkana Water and Sewerage Company laboratories in Kitwe provided a means of monitoring the amount of ammonia generated. Chickens in house B showed a slightly faster growth rate from 28 to 42 days than those in house A. The f-test results from the study showed that there was a significant effect of ammonia concentration on chicken growth rate P0.05. The results obtained from excreta-litter mixture analysis showed a significant adsorption of ammonia by bamboo charcoal P0.05. The study further indicated a direct dependency of ammonia concentration in excreta on chicken age moisture content and pH.

    Oleic acid alkyl esters (biodiesel) were synthesised by biocatalysis in solvent-free conditions. Different commercial immobilised lipases, namely Candida antarctica B, Rizhomucor miehei, and Pseudomonas cepacia, were tested towards the reaction between triolein and butanol to produce butyl oleate. Pseudomonas cepacia lipase resulted to be the most active enzyme reaching 100% of conversion after 6h. Different operative conditions such as reaction temperature, water activity, and reagent stoichiometric ratio were investigated and optimised. These conditions were then used to investigate the effect of linear and branched short chain alcohols. Methanol and 2-butanol were the worst alcohols: the former, probably, due to its low miscibility with the oil and the latter because secondary alcohols usually are less reactive than primary alcohols. Conversely, linear and branched primary alcohols with short alkyl chains (C(2)--C(4)) showed high reaction rate and conversion. A mixture of linear and branched short chain alcohols that mimics the residual of ethanol distillation (fusel oil) was successfully used for oleic acid ester synthesis. These compounds are important in biodiesel mixtures since they improve low temperature properties.

    1981-09-15

    Radappertization, or irradiation sterilization of meats and other protein foods (poultry, seafoods) is a new processing method applicable to pre-cooked (enzyme inactivated) foods that are hermetically sealed (either in metal cans, flexible pouches, or metal or plastic trays) and involves irradiation to sterilizing doses of either gamma rays (from a cobalt-60 or caesium-137 source) or by X-rays and electrons. The process is particularly applicable to pre-cooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been

    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.

    2010-10-01

    To generate information essential for the implementation of breeding schemes suitable for village poultry producers in Ethiopia, a survey was conducted aimed at defining the socioeconomic characteristics of the production environments in different geographic regions, understanding the important functions of chickens, identifying farmers' choice of chicken breeds and the underlying factors that determine the choice of genetic stock used. The survey included both questionnaire survey and a participatory group discussion. A total of 225 households (45 households from each of five Woredas) were interviewed. The questionnaire was designed to collect data covering general information on village poultry production such as socio-management characteristics, production objectives, population structure, breed choice and trait preferences, market preferences of specific traits, and farmers' selection practices. The participatory farmers' discussions were designed to involve stakeholders in defining the breeding objective "traits" and deriving their relative importance in the production environment based on the different functions of chickens and "traits" identified in the interviews. The results showed that production of eggs for consumption is the principal function of chickens in most regions followed by the use as source of income and meat for home consumption. The production system in all geographic regions studied revealed similar features generally characterized by extensive scavenging management, absence of immunization programs, increased risk of exposure of birds to disease and predators, and reproduction entirely based on uncontrolled natural mating and hatching of eggs using broody hens. Farmers' ratings of indigenous chickens with respect to modern breeds showed the highest significance of the adaptive traits in general, and the superior merits of indigenous chickens to high yielding exotic breeds in particular. Adaptation to the production environment was the most

As compared with basic textile and apparel products, fast fashion products are complex in their own way. A single assortment contains several new styles, colors, and sizes with unpredictable demand and urgent deadlines. Numerous assortments run simultaneously in the supply chain. For each assortment, the garment manufacturer has to source various types of fabrics and materials from different suppliers and then manufacture the garments to ship within the deadlines. This complexity contributes to supply chain disruption. This paper develops a model to estimate supply chain disruption cost as a function of fast fashion product complexity in the global outsourcing environment. Estimation of disruption cost will help us to increase visibility and eliminate the bottlenecks in supply chain. Model conclusions are used to develop a method to manage the level of product complexity from the global supply chain perspective. Several strategies are proposed to manage the impact of product complexity on supply chain design.

    Supply chain carbon emission is one of the factors considered in the green supply chain management. A method was designed to support the green supply chain measures based on the carbon footprint assessment for products. A research for 3 typical household appliances carbon footprint assessment was conducted to explore using product carbon footprint assessment method to guide the green supply chain management of the manufacturers. The result could reflect the differences directions on green supply chain management of manufacturers of washing machine, air conditioner and microwave, respectively That is, the washing machine manufacturer should pay attention to the low carbon activities in upstream suppliers in highest priority, and also the promotion of product energy efficiency. The air conditioner manufacturer should pay attention to the product energy efficiency increasing in highest priority, and the improvement of refrigerant to decrease its GWP. And the microwave manufacture could only focus on the energy efficiency increasing because it contributes most of the carbon emission to its carbon footprint. Besides, the representativeness of product and the applicability of the method were also discussed. As the manufacturer could master the technical information on raw material and components of its products to conduct the product carbon footprint assessment, this method could help the manufacturer to identify the effective green supply chain measures in the preliminary stage.

    Sinaga, A. T.; Wangsaputra, R.

    2018-03-01

    The development of technology causes the needs of products and services become increasingly complex, diverse, and fluctuating. This causes the level of inter-company dependencies within a production chains increased. To be able to compete, efficiency improvements need to be done collaboratively in the production chain network. One of the efforts to increase efficiency is to harmonize production and distribution activities in the production chain network. This paper describes the harmonization of production and distribution activities by applying the use of push-pull system and supply hub in the production chain between two companies. The research methodology begins with conducting empirical and literature studies, formulating research questions, developing mathematical models, conducting trials and analyses, and taking conclusions. The relationship between the two companies is described in the MINLP mathematical model with the total cost of production chain as the objective function. Decisions generated by the mathematical models are the size of production lot, size of delivery lot, number of kanban, frequency of delivery, and the number of understock and overstock lot.

    Establishing a mathematical supply-chain model is a proposition that has received attention due to its inherent benefits of evolving global supply-chain efficiencies. This paper discusses the prevailing relationships found within apparel supply-chain environments, and contemplates the complex issues indicated for constituting a mathematical model. Principal results identified within the data suggest, that the multifarious nature of global supply-chain activities require a degree of simplification in order to fully dilate the necessary factors which affect, each sub-section of the chain. Subsequently, the research findings allowed the division of supply-chain components into sub-sections, which amassed a coherent method of product development activity. Concurrently, the supply-chain model was found to allow systematic mathematical formulae analysis, of cost and time, within the multiple contexts of each subsection encountered. The paper indicates the supply-chain model structure, the mathematics, and considers how product analysis of cost and time can improve the comprehension of product lifecycle management

    A model of a 3-stage food marketing chain is presented for the case of two products. Its extension of existing work is its capacity to examine non-competitive input and output markets in two marketing chains at once, and have them related by demand and cost interactions. The simulated impacts...... of market power in a single chain generally reproduce those delivered by previous authors. The impacts of market power in related chains are found to depend on linkages between chains in terms of interactions in consumer demand. Interactions between products in costs (economies of scope) generate...... an interesting result in that a possible market failure is identified that may be offset by the exercise of market power. The generation of farm-level innovation is seen to be largely unaffected by market power, but where market power is exercised the benefits are extracted from farmers and consumers...

    2013-08-01

    The objective of this study was to identify ingredients that inhibit Listeria monocytogenes in natural, organic, or clean-label ready-to-eat meat and poultry products. Fourteen ingredients were screened in uncured (no-nitrate-or-nitrite-added), traditional-cured (156 ppm of purified sodium nitrite), cultured (alternative cured, natural nitrate source, and Staphylococcus carnosus), or preconverted (alternative cured, natural nitrite source) turkey slurries. Slurries were cooked, cooled, inoculated to yield 3 log CFU/ml L. monocytogenes, stored at 4°C, and tested weekly for 4 weeks. Three antimicrobial ingredients, 1.5 % vinegar-lemon-cherry powder blend, 2.5 % buffered vinegar, and 3.0 % cultured sugar-vinegar blend, were incorporated into alternative-cured ham and uncured roast beef and deli-style turkey breast. Controls included all three meat products without antimicrobial ingredients and a traditional-cured ham with 2.8 % sodium lactate-diacetate. Cooked, sliced products were inoculated with 3 log CFU/g L. monocytogenes, vacuum packed, and stored at 4 or 7°C, for up to 12 weeks. For control products without antimicrobial agents stored at 4°C, a 2-log L. monocytogenes increase was observed at 2 weeks for ham and turkey and at 4 weeks for roast beef. Growth (>1-log increase) in the sodium lactate-diacetate was delayed until week 6. Compared with the control, the addition of either vinegar-lemon-cherry powder blend or buffered vinegar delayed L. monocytogenes growth for an additional 2 weeks, while the addition of cultured sugar-vinegar blend delayed growth for an additional 4 weeks for both ham and turkey. The greatest L. monocytogenes delay was observed in roast beef containing any of the three antimicrobial ingredients, with no growth detected through 12 weeks at 4°C for all the treatments. As expected, L. monocytogenes grew substantially faster in products stored at 7°C than at 4°C. These data suggest that antimicrobial ingredients from a natural source

    Parenteral lipid emulsions are suspected of suppressing the immune function. However, study results are contradictory and mainly concern the conventional long-chain triglyceride emulsions. Polymorphonuclear leukocytes were preincubated with parenteral lipid emulsions. The influence of the lipid emulsions on the production of oxygen radicals by these stimulated leukocytes was studied by measuring chemiluminescence. Three different parenteral lipid emulsions were tested: long-chain triglycerides, a physical mixture of medium- and long-chain triglycerides, and structured triglycerides. Structured triglycerides consist of triglycerides where the medium- and long-chain fatty acids are attached to the same glycerol molecule. Stimulated polymorphonuclear leukocytes preincubated with the physical mixture of medium- and long-chain triglycerides showed higher levels of oxygen radicals (p triglycerides or structured triglycerides. Additional studies indicated that differences in results of various lipid emulsions were not caused by differences in emulsifier. The overall production of oxygen radicals was significantly lower after preincubation with the three lipid emulsions compared with controls without lipid emulsion. A physical mixture of medium- and long-chain triglycerides induced faster production of oxygen radicals, resulting in higher levels of oxygen radicals, compared with long-chain triglycerides or structured triglycerides. This can be detrimental in cases where oxygen radicals play either a pathogenic role or a beneficial one, such as when rapid phagocytosis and killing of bacteria is needed. The observed lower production of oxygen radicals by polymorphonuclear leukocytes in the presence of parenteral lipid emulsions may result in immunosuppression by these lipids.

    2017-11-01

    Full Text Available This paper addresses a coordination problem of production and green transportation and the effects of production and transportation coordination on supply chain sustainability in a global supply chain environment with the consideration of important realistic characteristics, including parallel machines, different order processing complexities, fixed delivery departure times, green transportation and multiple transportation modes. We formulate the measurements for carbon emissions of different transportation modes, including air, sea and land transportation. A hybrid genetic algorithm-based optimization approach is developed to handle this problem, in which a hybrid genetic algorithm and heuristic procedures are combined. The effectiveness of the proposed approach is validated by means of various problem instances. We observe that the coordination of production and green transportation has a large effect on the overall supply chain sustainability, which can reduce the total supply chain cost by 9.60% to 21.90%.

    This article attempts to answer the question: What will most likely happen in terms of emitted greenhouse gases if the use of poultry fat for making biodiesel used in transportation is increased? 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...

    Full Text Available Warqe (Enset is a multipurpose perennial plant, domesticated and grown as a food crop only in Ethiopia. Kocho, bulla, and amicho are food products of warqe. This study analysed the supply chain and logistics practices of warqe foods. Supply chain management concept was used to analyse the warqe-based food chain. Eight supply chain actors were identified. It was observed that the supply chain of warqe foods and the relationship between chain actors was very complex, long and overlapping. The major constraints identified in the chain were poor information flow, poor transportation system, using perishable packaging, lack of cooperation between actors, a poor infrastructure such as road and warehouse services, and poor policies concerning the warqe market. There is a need for cooperation and coordination between the chain actors to create an effective information sharing system. Shared warehouses need to be built near producers and market places. Transportation, packaging and handling need to be improved. Research is required to develop an integrated, efficient and effective logistics for warqe supply and marketing chain.

    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

    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.

    Radappertization is particularly applicable to precooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been designated as the leading agency for the US Federal food and nutrition programmes

  6. Modeling and Optimization of Inventory-Distribution Routing Problem for Agriculture Products Supply Chain

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Mathematical models of inventory-distribution routing problem for two-echelon agriculture products distribution network are established, which are based on two management modes, franchise chain and regular chain, one-to-many, interval periodic order, demand depending on inventory, deteriorating treatment cost of agriculture products, start-up costs of vehicles and so forth. Then, a heuristic adaptive genetic algorithm is presented for the model of franchise chain. For the regular chain model, a two-layer genetic algorithm based on oddment modification is proposed, in which the upper layer is to determine the distribution period and quantity and the lower layer is to seek the optimal order cycle, quantity, distribution routes, and the rational oddment modification number for the distributor. By simulation experiments, the validity of the algorithms is demonstrated, and the two management modes are compared.

  7. Efficient odd straight medium chain free fatty acid production by metabolically engineered Escherichia coli.

    Free fatty acids (FFAs) can be used as precursors for the production of biofuels or chemicals. Different composition of FFAs will be useful for further modification of the biofuel/biochemical quality. Microbial biosynthesis of even chain FFAs can be achieved by introducing an acyl-acyl carrier protein thioesterase gene into E. coli. In this study, odd straight medium chain FFAs production was investigated by using metabolic engineered E. coli carrying acyl-ACP thioesterase (TE, Ricinus communis), propionyl-CoA synthase (Salmonella enterica), and β-ketoacyl-acyl carrier protein synthase III (four different sources) with supplement of extracellular propionate. By using these metabolically engineered E. coli, significant quantity of C13 and C15 odd straight-chain FFAs could be produced from glucose and propionate. The highest concentration of total odd straight chain FFAs attained was 1205 mg/L by the strain HWK201 (pXZ18, pBHE2), and 85% of the odd straight chain FFAs was C15. However, the highest percentage of odd straight chain FFAs was achieved by the strain HWK201 (pXZ18, pBHE3) of 83.2% at 48 h. This strategy was also applied successfully in strains carrying different TE, such as the medium length acyl-ACP thioesterase gene from Umbellularia californica. C11 and C13 became the major odd straight-chain FFAs. © 2014 Wiley Periodicals, Inc.

  8. The Supply Chain Triangle: How Synchronisation, Stability, and Productivity of Material Flows Interact

    Directory of Open Access Journals (Sweden)

    Florian Klug

    2013-01-01

    Full Text Available Empirical evidence created a commonly accepted understanding that synchronisation and stability of material flows impact its productivity. This crucial link between synchronous and stable material flows by time and quantity to create a supply chain with the highest throughput rates is at the heart of lean thinking. Although this supply chain triangle has generally been acknowledged over many years, it is necessary to reach a finer understanding of these dynamics. Therefore, we will develop and study supply chains with the help of fluid dynamics. A multistage, continuous material flow is modelled through a conservation law for material density. Unlike similar approaches, our model is not based on some quasi steady-state assumptions about the stochastic behaviour of the involved supply chain but rather on a simple deterministic rule for material flow density. These models allow us to take into account the nonlinear, dynamical interactions of different supply chain echelons and to test synchronised and stable flow with respect to its potential impacts. Numerical simulations verify that the model is able to simulate transient supply chain phenomena. Moreover, a quantification method relating to the fundamental link between synchronisation, stability, and productivity of supply chains has been found.

    We study the scalar products between Bethe states in the XXZ spin chain with anisotropy |Δ|>1 in the semi-classical limit where the length of the spin chain and the number of magnons tend to infinity with their ratio kept finite and fixed. Our method is a natural yet non-trivial generalization of similar methods developed for the XXX spin chain. The final result can be written in a compact form as a contour integral in terms of Faddeev’s quantum dilogarithm function, which in the isotropic limit reduces to the classical dilogarithm function.
