Consumer Interest in Environmentally Beneficial Chicken Feeds: Comparing High Available Phosphorus Corn and Other Varieties AgEcon
Pesek, John D., Jr.; Bernard, John C.; Gupta, Meeta.
One source of phosphorous pollution in areas of high chicken production is runoff from fields using fertilizer from these operations. A potential solution is to feed chicken high available phosphorus (HAP) corn, reducing phosphorus in manure. This study examined consumer purchase likelihood of chickens fed HAP, created traditionally or through genetic modification, and other genetically modified (GM) corn including Bt and Roundup-ready. Survey results from the Delmarva Peninsula found considerable interest in non-GM HAP corn, although GM HAP corn was not typically viewed as more acceptable than other GM varieties. Overall, the marketplace appears open to products geared toward environmental benefits.

CONSUMER KNOWLEDGE OF SELECTED NUTRIENT CONTENT OF NINE FRESH MEAT CUTS AgEcon
Reed, Debra; Gillespie, Jeffrey M.; Downer, Robert; Schupp, Alvin R..
The U.S. Department of Agriculture, the Food and Drug Administration, and the medical profession, among others, have attempted to broaden consumers' knowledge of the nutritive content of foods. Retailers provide information by supplying point-of-purchase nutrition information and/or nutrition labels on fresh meats. The availability of nutrition information on packaged fresh meats is relatively new. A survey of Louisiana households provided estimates of their knowledge of the fat, cholesterol, and protein content of selected combinations of fresh beef, pork, chicken, and turkey meats. Permutation analysis and tabular analyses were used to assess households' nutrition knowledge of the selected fresh meats.

Consumer Likelihood to Purchase Chickens with Novel Production Attributes AgEcon
Bernard, John C.; Pesek, John D., Jr.; Pan, Xiqian.
Typical supermarket chickens are produced with novel or controversial attributes. This continues despite contrasting growth in consumer interest in organic and natural foods. This study surveyed Delaware consumers’ likelihood to purchase chicken given different attributes: free range, given antibiotics, irradiated, fed genetically modified (GM) fee, GM chicken, and price. Examining conjoint analysis data with a heteroskedastic two-limit tobit model, GM chicken and other novel attributes were found to lower purchase likelihood significantly. Understanding these results should help the industry meet consumer preferences while aiding its continued expansion to benefit workers and growers across the South.

Cryopreservation of an avian spirochete strain in liquid nitrogen Arq. Bras. Med. Vet. Zootec.
Labruna,M.B.; Resende,J.S.; Martins,N.R.S.; Jorge,M.A..
Soros de aves experimentalmente infectadas, contendo espiroquetas viáveis, foram submetidos a dois procedimentos antes da criopreservação: glicerol na diluição de 1/2 (v/v), designado como soro com glicerol a 50% (GS), e dimetilsulfóxido na proporção de 1/10 (v/v), designado como soro com DMSO a 10% (DS). Após 15 meses de estocagem em nitrogênio líquido, amostras dos tratamentos GS e DS foram descongeladas e suas infectividades foram testadas em frangos susceptíveis. Apesar de ambos os procedimentos terem mantidos a infectividade da bactéria, DMSO a 10% no soro de frango apresentou-se mais satisfatório como criopreservante.

Desafios na construção participativa da pesquisa sobre transição agroecológica: alimentos alternativos para galinhas poedeiras. Repositório Alice
JULIANO, R. S.; LISITA, F. O.; TIAMBO, C. K.; SOARES FILHO, M. da S.; FELIX, G. A..
A produção de ovos, mesmo em pequena escala ou em sistemas produtivos mais rústicos, depende do uso de grãos (milho e soja) para a elaboração de uma dieta balanceada para os animais. Destaca-se que esses ingredientes não são produzidos no Pantanal, não são facilmente acessíveis e tem alto preço para compra. Nesse contexto, o uso de alimentos, com possibilidade de produção local, em substituição ao uso de milho e soja é uma demanda importante para o desenvolvimento de dietas alternativas para pequenos produtores, agricultura de subsistência ou sistemas produtivos em transição agroecológica e orgânicos. Com essa justificativa foi executado um experimento com o objetivo de incluir alimentos (mandioca, moringa e bocaiuva), com possibilidade de produção na...

Differential expression of the MHM region and of sex-determining-related genes during gonadal development in chicken embryos. Repositório Alice
CAETANO, L. C.; GENNARO, F. G. O.; COELHO, K.; ARAÚJO, F. M.; VILA, R. A.; ARAÚJO, A.; BERNARDO, A. de M.; MARCONDES, C. R.; LOPES, S. M. C. de S.; RAMOS, E. S..
The chicken (Gallus gallus) embryo has been used as a classic model system for developmental studies because of its easy accessibility for surgical manipulation during embryonic development. Sex determination in birds is chromosomally based (ZZ for males and ZW for females); however, the basic mechanism of sex determination is still unknown. Here, the dynamics of expression of candidate genes implicated in vertebrate sex determination and differentiation were studied during embryonic chicken gonadal development. Gene expression profiles were obtained before, during, and after gonadal sex differentiation in females and males for DMRT1, SOX3, SOX9, DAX MHM and sex-determining gene expression in chicken embryos SCII, HINTZ, HINTW, and the male hypermethylated...

Dynamics of Price Transmission in the Presence of a Major Food Safety Shock: Impact of H5N1 Avian Influenza on the Turkish Poultry Sector AgEcon
Saghaian, Sayed H.; Ozertan, Gokhan; Spaulding, Aslihan D..
This article addresses the dynamic impact of the 2005 H5N1 avian influenza outbreak on the Turkish poultry sector. Contemporary time-series analyses with historical decomposition graphs are used to address differences in monthly price adjustments between market levels along the Turkish poultry supply channel. The empirical results show that price adjustments are asymmetric with respect to both speed and magnitude along the marketing channel. Results also reveal a differential impact of the exogenous shock on producers and retailers. The findings have critical efficiency and equity implications for the supply-chain participants.

Evaluation of yeast culture and direct-fed microbial on gut histology and serum components of broilers challenged with suboptimal diets under heat stress Animal Sciences
Seifi, Saeed; Sayrafi, Reza; Khoshbakht, Rahem; Gilani, Ali; Goudarzi, Bahman.
The use of antibiotics in feed for growth promotion has been restricted in many countries, thus it is of interest to investigate potential alternatives for enhancing growth performance in birds. An experiment was carried out to evaluate the concurrent use of prebiotic and probiotic on gut histology and some blood chemicals of broiler chickens during heat stress. A total of 144 day-old male Ross 308 broiler chicks were randomly divided into 3 treatments. The first treatment was a diluted diet including rice bran without probiotic or prebiotic. The other treatments were fed the diluted diets with a prebiotic (treatment 2) and concurrent use of that prebiotic along with a probiotic (treatment 3). Results showed that villus height was not influenced by feed...

Evolution of urban chicken consumption in Southern countries: a comparison between Haiti and Cameroon AgEcon
Laroche Dupraz, Catherine; Awono, Cyprien.
Since the beginning of 2000s, in order to let poor people accede to meat consumption, several developing countries have opened their domestic chicken market to foreign imports, by reducing import tariffs. Thus local chicken meat competes with frozen pieces of chicken imported from the European Union or America, causing the loss of many jobs in the local chicken food chain. In order to highlight the determinants of urban consumer’s choice relative to chicken types, and assess the opportunity for local chicken to restore its market share, investigations have been done in 2005 and 2006, in Yaoundé (Cameroon) and at Port-au-Prince (Haiti) applied to 180 urban households in each country. While imported frozen pieces of chicken have almost entirely substituted...

Food Scares and Consumer Behaviour: A European Perspective AgEcon
Mazzocchi, Mario; Lobb, Alexandra E.; Traill, W. Bruce.
In this paper a consumer food choice model based on the Theory of Planned Behaviour (TPB) is extended to account for risk perception and trust. The data are from a nationally representative European survey of 2 725 respondents from five countries, France, Germany, Italy, Netherlands and the United Kingdom. The model relates the intention to purchase chicken in an extended TPB framework, which incorporates risk perceptions, and trust in alternative sources of food safety information. This model was run for two behaviours of interest: the standard likelihood of intention to purchase and the likelihood of intention to purchase conditional on news about a salmonella incident. The model has good predictive power and shows distinct country differences. Only in...

Institutionalized Metzler Effects: Tariff-Rate Quota Liberalization in a Supply-Managed Industry AgEcon
Pouliot, Sebastien; Larue, Bruno.
A supply management system governs Canada’s poultry sector. Tariff Rate Quotas (TRQs), with prohibitive above-quota tariffs and low in-quota tariff, mimic import-quotas limit international competition in Canada’s poultry market. The quota part of the TRQs is a minimum access commitment under international trade agreement that is defined as a fraction of domestic production. We show in a 3-stage game involving negotiations between retailers and processors and between processors and farms that increasing minimum access commitment under current trade agreements can produce Metzler effects with larger price increases observed at the farm and processing levels. Simulations based on 2008 data support the Metzler paradox and shed light on import license...

Integrative mapping analysis of chicken microchromosome 16 organization Inra
Solinhac, R.; Leroux, S.; Galkina; Chazara, O.; Feve, K.; Vignoles, F.; Morisson, M.; Derjusheva; Bed'Hom, B.; Vignal, A.; Fillon, V.; Pitel, F..
The chicken karyotype is composed of 39 chromosome pairs, of which 9 still remain totally absentfrom the current genome sequence assembly, despite international efforts towards complete coverage. Someothers are only very partially sequenced, amongst which microchromosome 16 (GGA16), particularly underrepresented,with only 433 kb assembled for a full estimated size of 9 to 11 Mb. Besides the obvious need of fullgenome coverage with genetic markers for QTL (Quantitative Trait Loci) mapping and major genes identificationstudies, there is a major interest in the detailed study of this chromosome because it carries the two geneticallyindependent MHC complexes B and Y. In addition, GGA16 carries the ribosomal RNA (rRNA) genes cluster, alsoknown as the NOR...

Measuring Consumer Willingness to Pay for a Health Risk Reduction of Salmonellosis and Campylobacteriosis AgEcon
Goldberg, Isabell; Roosen, Jutta.
This paper presents an application of the contingent valuation method (CVM) and choice experiments (CEs). We examine consumer willingness to pay (WTP) for different health risk reduction levels of Salmonellosis and Campylobacteriosis acquired from the consumption of chicken breast. We test for the embedding effect. The embedding effect was not found in the CVM format. It was however present in the CEs. The WTP values in the CVM format rages from Euro 1.29 to 3.34, whereas the WTP obtained by the CEs ranges from Euro -0.16 to Euro 6.68 depending on the disease and the corresponding risk reduction levels.
