Impacto socioeconômico das políticas sanitárias sobre os estabelecimentos avícolas comerciais de postura da regional agropecuária de Limeira, estado de São Paulo

É reconhecida a importância da avicultura para o agronegócio e para o desenvolvimento do Brasil. Mas o País tem enfrentado grande concorrência internacional, que se traduz em barreiras sanitárias e exigências cada vez maiores de controle de seu rebanho por parte dos importadores. Neste sentido, o Ministério da Agricultura, Pecuária e Abastecimento (MAPA) publicou uma série de atos legais para viabilizar a organização dos programas de saúde animal, entre eles as Instruções Normativas n° 56/2007, n° 59/2009, n°36/2012 e n°10/2013, para estabelecer os procedimentos para registro e fiscalização de estabelecimentos avícolas comerciais e de reprodução, voltados à biosseguridade do sistema avícola. Como todos os setores produtivos, a avicultura é fortemente influenciada pela sua estrutura de custos, de modo que há um certo sentimento de que a adequação às medidas de biosseguridade, preconizadas pelas normativas, pode impactar a atividade de produção de ovos comerciais de modo a levar, eventualmente, alguns avicultores ao abandono da mesma. O objetivo deste trabalho foi analisar o impacto socioeconômico das políticas sanitárias para estabelecimentos avícolas comerciais de postura da regional agropecuária de Limeira, Estado de São Paulo, analisando o perfil socioeconômico da propriedade e do produtor e, estimando o custo de produção e seu impacto em atendimento às medidas de biosseguridade preconizadas pelas normativas. Para a análise do perfil das propriedades foram utilizados os dados dos 28 estabelecimentos avícolas, levantados por meio de documentação para registro. Para a análise do perfil do produtor e para estimar os custos de produção foram considerados dez estabelecimentos, voluntários à pesquisa, visitados entre os meses de junho e julho de 2013. O resultado do estudo sugere que as adequações à biosseguridade podem ser factíveis de serem realizadas economicamente, sendo o custo relativamente pequeno frente aos possíveis riscos de enfermidades, representando entre 1,61% e 2,09% do custo total de produção. No entanto, as sucessivas alterações nas legislações podem fazer com que o programa de sanidade avícola perca a credibilidade diante da sociedade e dos produtores que demonstram resistência às mudanças nos paradigmas zoosanitários

The Farm-Retail Price Spread in an Imperfectly Competitive Food Industry

Gardner's popular model of perfect competition in the marketing sector is extended to a conjectural-variations oligopoly with endogenous entry. Revising Gardner's comparative statics on the "farm-retail price ratio," tests of hypotheses about food industry conduct are derived. Using data from a recent article by Wohlgenant, which employs Gardner's framework, tests are made of the validity of his maintained hypothesis-that the food industries are perfectly competitive. No evidence is found of departures from competition in the output markets of the food industries of eight commodity groups: (a) beef and veal, (b) pork, (c) poultry, (d) eggs, (e) dairy, (f) processed fruits and vegetables, (g) fresh fruit, and (h) fresh vegetables.

RB31-258 The Contribution fo Nebraska Farm Women to Family Income Through Poultry and Dairy Products

This investigation was made in 1929-1930 for the purpose of studying the activities of Nebraska farm women in the raising of poultry and in the care of dairy products, to discover whether or not such activities resulted in a contribution to the family income. With this in view, a group of women were asked to keep records for one year (from April 1, 1929 to March 31, 1930) of the value and amount of dairy and poultry products sold or used, of all expense incurred in production, and of the time spent both by the homemaker herself and by all other members of the household, in the production and sale of dairy and poultry products. When this study was outlined it was intended to cover only actual cash addition to the family income. This, however, did not prove to be feasible, as a considerable portion of the contribution to the family income was in the form of dairy and poultry products used at home.

Contribution to economic evaluation of systems that value animal welfare at farm

The demand for "welfare friendly" products increases as public conscience and perception on livestock production systems grow. The public and policy-makers demand scientific information for education and to guide decision processes. This paper describes some of the last decade contributions made by scientists on the technical, economical and market areas of farm animal welfare. Articles on animal welfare were compiled on the following themes: 1) consumer behavior, 2) technical and economical viability, 3) public regulation, and 4) private certification policies. Most studies on the economic evaluation of systems that promote animal welfare involved species destined to produce export items, such as eggs, beef and pork. Few studies were found on broilers, dairy cows and fish, and data regarding other species, such as horses, sheep and goats were not found. Scientists understand that farm animal welfare is not only a matter of ethics, but also an essential tool to gain and maintain markets. However, it is unfortunate that little attention is paid to species that are not economically important for exports. Studies that emphasize on more humane ways to raise animals and that provide economic incentives to the producer are needed. An integrated multidisciplinary approach is necessary to highlight the benefits of introducing animal welfare techniques to existing production systems.

The influence of captive breeding on the fatty acid profiles of Salminus hilarii (Characiformes: Characidae) eggs and larvae

In addition to the strong influence of the broodstock diet on the development and survival of offspring, domestication may also interfere with the larval life success. We obtained eggs from wild and domesticated Salminus hilarii females and domesticated males. Wild females were caught in the Tiete River and tributaries, and the domesticated females were born three years before the beginning of the experiment in the Ponte Nova Fish Farm. Animals from both groups were fed with the same feed to exclude feed variables. The eggs and larvae were sampled at 0, 8, 16, and 28 h after spawning (HAS), with the last sampling (28 HAS) coinciding with hatching time. After hatching, samplings proceeded at 32, 48, 66, and 96 HAS, with the last sampling (96 HAS) corresponding to the end of yolk sac consumption. Finally, the last experimental period was during the larvae exogenous feeding phase, at 102, 118, 166, and 214 HAS. Our data revealed that domestication of S. hilarii females influenced fatty acid (FA) metabolism during embryo and larva development. However, the structure of membrane phospholipid FA remained mostly stable, with changes principally in the neutral fraction. When the external conditions, mainly water and feed quality, remained constant, domestication of S. hilarii females did not significantly affect the structural FA composition but influenced the selectivity of consumption and/or storage of specific FA.

Enterobacteria Isolation in Ostrich Eggs (Struthio camelus)

This study was conducted to determine the presence of enterobacteria in the eggs of ostriches reared on a farm with a history of reproductive failure. Ninety samples from twenty eggs were submitted to bacteriological tests. The results showed Enterobacteria growth in 100% of the eggs. The microorganisms isolated were Hafnia alvei in 50% (10/20), Serratia spp. in 20% (4/20), Escherichia coli in 15% (3/20), and Citrobacter freundii in 15% (3/20). All eggs presented poor eggshell quality, which favored enterobacteria contamination. Hafnia alvei was present only in the internal egg structures (albumen and yolk sac), suggesting the possibility of vertical infection.

Isolation and recognition Saprolegnia species from fungal infected eggs of the rainbow trout in Mazandaran province farms

Fungal infection in the eggs of freshwater fish is well known as a problematic disease. That isolation and recognition Saprolegnia fungi from fungal infected eggs of the rainbow trout in Mazandaran province was the aim of this research. For this purpose fungal infected eggs were examined from six fish farm in the fall and winter 2005-2006. The eggs with fungi were inoculated on SDA, CMA, GPagar and hemp seed and sesame seed cultures in sterile tap water at room temperature (18-24°C). In this study recognized three genera and six species Saprolegniaceae members, based on morphological characteristics which contain: Saprolegnia, Achlya, Brevilegnia. Four species were identified in the genus Saprolegnia; S.mixta, S.parasitica, S.moniliphera, S.lapponica and one species was identified in the genus Achlya; A.oblongata. S.parasitica was isolated from almost all the farms. In addition, another nine genera and species were identified; Penicillium, Aspergillus, Paeciliomyces, Acremonium, Fusarium oxysporum, F.solani , Alternaria, Helminthosporium, Mucor.
