| En la alimentación humana, la carne es una parte importante de la dieta, representa aproximadamente 11% del total del consumo de alimentos. La carne de pollo, por su alto valor nutrimental, bajo costo y alta disponibilidad, es uno de los productos de origen animal de mayor consumo y aceptación. Lo que ha resultado que a nivel mundial, en los últimos 30 años su producción se haya cuadruplicado, mientras que la de otras especies, como la de cerdo, sólo ha duplicado su volumen (FAO, 2007). En las últimas décadas una parte importante de la investigación en el ámbito de la nutrición animal se ha dirigido a mejorar el valor nutritivo de los alimentos de origen animal, para ofrecer al consumidor un producto de acuerdo a su demanda y necesidades, con... |

| ABSTRACT: The aim of the present study was to assess the occurrence of aflatoxins (AFs) and fumonisins (FBs) in feed ingredients (corn and soybean meal) and finishing feed in a broiler operation system, as well was to evaluate their effect on the productivity of 20 batches of broilers produced and the histology status of broilers’ liver after slaughter. Corn samples presented the highest frequencies of AFs and FBs, at mean levels of 29.1 and 2,100µg/kg, respectively. Soybean samples presented mean levels of 1.5 and 70µg/kg for AFs and FBs, respectively. Batches of broilers receiving feed containing FB levels higher than 1,000µg/kg had lower weight gain and higher mortality rates, while those fed rations with AFs equal or above the limit of quantification... |

| Um dos poluentes aéreos frequentemente encontrados em altas concentrações nos aviários é a amônia a qual é considerada o gás mais prejudicial na produção de aves. Dessa forma, objetivou-se avaliar a concentração de amônia no ar em aviário dark house. Os dados de concentração de amônia no ar foram coletados em 27 pontos no sentido longitudinal do aviário, à altura das aves, no primeiro e nos 21 e 42 dias de vida por seis lotes consecutivos. De acordo com os valores de amônia em cada ponto, foi realizada análise geostatística utilizando o software GS+􀂓. A partir da análise espacial foram confeccionados mapas de isolinhas das medidas de amônia utilizando o software SURFER􀂓. A distribuição de amônia foi heterogênea ao longo do aviário... |

| International studies and epidemiological data have revealed a strong association between salmonellosis and chicken meat. This association provides serious challenges for food safety and international trade. Microbiological Risk Assessment is a food safety tool that is used to determine the incidence of food borne illnesses. The procedure identifies a microbiological hazard in the entire food continuum (from farm to fork), and estimates the adverse effects to human health, of ingesting the microbial hazard. The Assessment integrates four steps, hazard identification, hazard characterisation, exposure assessment and risk characterisation, to produce a practical estimate of risk. In each step, knowledge of the prevalence and concentration of the pathogen,... |

| Resumo: Com a necessidade de buscar alimentos alternativos que visam baratear os custos na ração de frangos de corte e reaproveitar os resíduos de incubatório que compreendem material residual do processo de incubação, objetivou-se avaliar a digestibilidade e valor energético do ovo em pó desidratado para frangos de corte. Foram utilizados 300 frangos machos da linhagem COBB, distribuídos em delineamento experimental inteiramente casualizado, composto por dois tratamentos constituídos por cinco repetições, com três animais em cada repetição. O experimento foi composto por um tratamento controle (ração referência) e um tratamento composto por ração referência + 15% de ovo desidratado em pó. Foi utilizado o método de coleta total de excretas para realizar as... |

| ABSTRACT The 21 days feeding trial was conducted on 90, Cobb 500 broilers (aged 14 days), assigned to 3 groups (C, E1 and E2) housed in an experimental hall at 32° C constant temperature and 23 h light regimen. During the growth period (14-35 days), the conventional diet (C) had corn and soybean meal as basic ingredients. Unlike the conventional diet formulation (C), the diet formulations for the experimental groups also included 0.005% Artemisia annua oil (E1) and 0.005% Artemisia annua oil plus 1% Artemisia annua powder (E2). Six broilers per group were slaughtered at 35 days of age in order to measure the weight of the carcass and internal organs of broilers, and samples of intestinal and caecal content were collected for bacteriological assessment... |

| Abstract: Intense selection for production traits has improved the genetic gain of important economic traits. However, selection for performance and carcass traits has led to the onset of locomotors problems and decreasing bone strength in broilers. Thus, genes associated with bone integrity traits have become candidates for genetic studies in order to reduce the impact of bone disorders in broilers. This study investigated the association of the RUNX2 and TNFSF11 genes with 79 traits related to performance, carcass composition, organs, and bone integrity in a paternal broiler line. Analyses of genetic association between single-nucleotide polymorphisms (SNPs) and traits were carried out using the maximum likelihood procedures for mixed models. Genetic... |

| Two experiments were conducted in order to evaluate the effects of different dietary amino acid and calcium profiles on the bone characteristics of two chicken strains (Avian Farms and Cobb) during the starter phase. At the end of each experiment, 2 chickens of each replicate were sacrificed and their tibiae were collected for analysis of following bone characteristics: bone measurements (weight, length and thickness of the compact and spongy layers) and bone density (bone densitometry). A total of 540 birds were used in each experiment, divided into fully randomized blocks with a 3 x 2 factorial schemes, i. e., 3 amino acid profiles (methionine, lysine and threonine ­ 100%, 125% and 150% of NRC recommendations, 1994) and 2 calcium levels (75% and... |

| In the present study we have investigated the effects of heat acclimation on brain and hepatic Hsp70 protein levels and body temperature of broiler chickens in response to gradual heat stress. Two groups of broilers were raised up to 47 days of age under distinct temperature conditions: thermoneutral (TN, according to bird age) or hot environmental (HS, 31-33°C). At 46 days of age, the birds reared at high ambient temperature were transferred to thermoneutrality conditions. After 18 h, these birds and the birds reared at thermoneutral temperature were submitted to gradual heat stress in a climatic chamber so that environment temperature was increased from 28 to 40ºC at a rate of 2ºC/h. Colonic temperature was measured using a thermometer sensor probe at... |

| 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... |
