A produção nacional de frango de corte tem se destacado entre os demais setores produtivos nas últimas décadas. O exponencial desempenho do setor possibilitou ao Brasil assumir posição de destaque no ranking mundial, como o maior exportador e terceiro maior produtor de carne de frango.  Apesar de todos os estados brasileiros produzirem carne de frango, a produção está concentrada na Região Sul do País, sendo o Paraná o principal produtor e exportador de aves do País. Nesse cenário, o objetivo principal deste trabalho foi analisar a especialização da produção de frango de corte, através do Quociente Locacional (QL) e analisar as exportações por meio do Market-Share (MS).  Os principais resultados obtidos apontam que o avanço da tecnologia na produção, melhoramento dos índices de conversão alimentar, genética, entre outros, contribuíram para a evolução do setor, tanto em termos de produção quanto em exportação. Neste sentido a região Sul é a mais desenvolvida e especializada neste segmento. O sistema de contrato de integração facilitou o elo entre produtores rurais e agroindústria, com o fornecimento da matéria-prima e assistência técnica, e o produtor com a mão de obra e estrutura necessária. ABSTRACT The national production of broiler chicken has been outstanding among the other productive sectors in the last decades. The exponential performance of the sector enabled Brazil to take a leading position in the world ranking, as the largest exporter and third largest producer of chicken meat. Although all Brazilian states produce chicken meat, production is concentrated in the Southern Region of the country, with Paraná being the main producer and exporter of poultry in the country. In this scenario, this article had as main objective the analysis of the evolution of the poultry production in Brazil from 1995 to 2015, for that the analysis of the specialization of the production of broiler chicken was made through the Locational Quotient (QL) and the analysis of the productive concentration of the exports was made through Market-Share (MS). The main results obtained indicate that the advances in technology in production, improvement of feed conversion, genetic indexes, among others, contributed to the evolution of the sector, both in terms of production and exports. In this sense, the South region is the most developed and specialized in this segment. The integration contract system facilitated the link between rural producers and agribusiness, with the supply of raw material and technical assistance, and the producer with the necessary manpower and structure. KEYWORDS: Poultry industry. Production Specialization. Export of chicken meat.

The aim of this experiment was to analyze the morphology of muscles and carcass quality Cobb-500 and Ross broiler chicken at different age, where the weight of live bird, carcass, major cut portions, lean and bone were measured. The average highest live weight at D35 was recorded as 1860.18±6.29g in Cobb-500 and 1640.47±7.57g in Ross broiler chicken. The average carcasses weights at D1, D7, D14, D21, D28 and D35 were recorded as 14.90 ±0.53g, 27.85±0.30g, 85.31±0.82g, 211.94±4.31g, 618.36 ±0.92g and 1289.05±5.39g for Cobb-500 and in case of Ross strains 12.89±0.41g, 25.83±0.38g, 82.09±0.35g, 210.58±2.66g, 565.55±2.41g and 1133.80±3.51g respectively. Highest dressing percentage was recorded at D35 which was 69.29±0.11g in Cobb-500 and 69.12±0.12g in Ross strains. The length, breadth, thickness and weight of pectoralis thoracis, supracoracoideus, iliotibialis lateralis and iliotibialis cranialis skeletal muscles were higher in Cobb-500 at every studied ages. Finally the experiment focused that Cobb-500 chicken is superior in terms of meat production for its unique skeletal muscle growth and carcass yield.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21265 Bangl.

Intervention Measures

Extended-spectrum beta-lactamase (ESBL) and AmpC beta-lactamase (AmpC) producing Enterobacteriaceae occur frequently in livestock animals and the subsequent stages of the meat production chain and are therefore considered a risk for human health. Strict biosecurity measures and optimal farm management should reduce or even prevent poultry flock colonization at farm level. This review summarizes and evaluates published information on the effectiveness of specific intervention measures and farm management factors aiming to reduce the occurrence and spread of ESBL/AmpC producing or commensal or pathogenic E. coli in broiler chicken farms. In this systematic literature review, a total of 643 publications were analyzed, and 14 studies with significant outcome about the effectiveness of specific measures against E. coli and ESBL/AmpC producing E. coli in broiler chicken farms were found. Different feed additives seem to have an impact on the occurrence of those microorganisms. The measures ‘cleaning and disinfection’ and ‘competitive exclusion’ showed strong effects in prevention in some studies. In summary, some intervention measures showed potential to protect against or eliminate ESBL/AmpC-producing, commensal or pathogenic E. coli at farm level. Due to the high variability in the outcome of the studies, more specific, detailed investigations are needed to assess the potential of the individual intervention measures.

Chicken meat tends to be high in polyunsaturated fatty acids and cholesterol, which may increase the risk of atherosclerosis, stroke and other associated diseases. A study was conducted for 42 days to evaluate the efficacy of dietary supplementation of two phytogenic feed supplements viz. AV/LMP/10 and AV/HLP/16 (M/s Ayurvet Limited, India) for their ability to produce lean meat in commercial broiler chicken. One hundred and fifty (150) one-day old Cobb-400 broiler chicks were randomly allocated to five equal groups. All the groups were fed standard basal ration. T0 was control group (without treatment), groups T1 and T2 were supplemented with AV/LMP/10 @ 500 g/ton and 1 kg/ton of feed, respectively. Groups T3 and T4 were supplemented with AV/HLP/16 @ 1 kg/ton and 1.5 kg/ton of feed, respectively. On day 42, significantly better (P<0.05) results were obtained in the treated groups (T1-T4) in terms of body weight (2118.10±0.61, 2159.20±0.34, 2098.90±0.41, and 2180.40±0.56 g), total protein (19.10±0.56, 19.93±1.18, 20.80±0.36, and 21.04±0.64%), crude fat (1.25 ±0.25, 1.25 ± 0.31, 0.92 ± 0.24, and 1.03 ± 0.03%), pH (6.01 ± 0.07, 5.93 ± 0.09, 5.78 ± 0.08, and 6.06 ± 0.09), TBARS value (1.11±0.07, 1.11±0.05, 1.06±0.06, and 1.08±0.06 mg/Kg), cholesterol (54.19±1.11, 35.72±1.71, 45.61±1.54, and 36.09±1.045 mg/dL), HDL cholesterol (16.70±0.56, 12.61±1.28, 14.16±1.02, and 15.59±0.57 mg/dL) and total lipids (1.60±0.13, 1.56±0.22, 1.64±0.15, and 2.03±0.12 mg/g) in comparison to the untreated group (2050.80±0.71 g, 18.15±0.41%, 1.66 ± 0.48%, 6.07 ± 0.08, 1.18±0.09 mg/Kg, 62.36±0.88 mg/dL, 24.25±0.54 mg/dL and 2.42±0.18 mg/g). FCR and slaughter parameters varied non-significantly among different groups. The meat: bone ratio was numerically higher in the treated groups T1-4 (2.01±0.20, 2.09 ±0.19, 2.16±0.20 and 1.89±0.35) as compared to the control group (1.80±0.18). The highest protein content was obtained in T4 (21.04%) followed by T3 (20.80%), T2 (19.93%), T1 (19.10%) and lowest in T0 (18.15%), while highest crude fat was obtained in the muscles of the control group T0 (1.66%) followed by T1 and T2 (1.25%), T4 (1.03%) and T3 (0.92). Overall sensory acceptability of meat also improved in the supplemented groups. From the present study, it could be concluded that the phytogenic formulations AV/LMP/10 and AV/HLP/16 were effective in lean meat production in broiler chicken.

AbstractGenetic progress in poultry species for meat production has contributed to the consistent growth in world production of poultry meat. The poultry species have a number of advantages over the larger species used for meat production. It is possible to maintain large pedigreed populations and use their high reproductive rates to transfer genetic progress to the production generations in less than five years. These populations continue to maintain high heritabilities despite, in some cases, prolonged selection. The history of selection progress in broiler chickens (Gallus gallus domesticus) is reviewed and compared with rates of progress in the duck (Anas platyrhyncos) and the turkey (Meleagris gallopavo).The rates of genetic change for production traits such as growth, feed efficiency and yield have changed the physiology of the birds. Changes in selection criteria have been made to improve the robustness of the production stock. This allows them to perform well in a wider range of environments. These have been combined with improved definitions of the optimum environments for the birds to minimise any impact on welfare and health. This paper describes examples of selection in the broiler chicken aimed at improving skeletal quality and resistance to ascites. A number of the factors influencing future selection criteria are discussed. Breeding programmes have adapted to respond quickly to adverse genetic correlated responses. The need to combine selection for a large number of traits requires that the programmes are very efficient and use the best statistical techniques available for multivariate breeding value estimation.
