“…Good management practices are essential for obtaining good broiler performance. It is important to stress that broiler production cycle is short (approximately 42 days), and therefore, any problems or mistakes are not likely to be corrected during the flock's life cycle (Leandro et al, 2006), and consequently may compromise final broiler performance. Table 2 shows that the average age of the interviewed broiler farmers was approximately 45.25 years, and ranged between 18 and 78 years of age.…”

This study aimed at identifying the factors that affect the financial performance of broiler chicken production in Southwest of Paraná state in Brazil, as well as to study the relationship of these factors with the social-economic situation of poultry farmers. Data were obtained from a questionnaire applied to broiler chicken farmers between February and March, 2011. The questionnaire included 39 questions relative to farmer's age, family size, land possession, capital invested in broiler farming, gross income per flock, training and broiler farming experience, production size, credit needs, technical service, labor, production problems, and bird weight at slaughter. Data were submitted to descriptive statistical analysis. The relationship between production data and financial performance was determined using Pearson correlation coefficient, at 95% confidence level. Approximately 64.84% of the interviewed broiler farmers in Paraná state presented medium to low financial performance. Factors such as education level, facility size, labor, gross income per flock, and average bird weight at slaughter had a positive impact on financial performance. The production problems that most affected the broiler production were environmental challenges, poor feed conversion, as well as management problems and low-quality chicks.

“…Neste período, os animais ganharam 71,2 gramas. Nesta oportunidade acreditava-se que a adição de silagem de peixes geraria resultados satisfatórios uma vez que, o peso inicial do pintinho influencia o peso vivo, o ganho de peso e o consumo de ração nos diferentes períodos de crescimento, além do índice de eficiência produtiva, ou seja, pintinhos mais pesados apresentarão, aos 47 dias de idade, melhores resultados de desempenho (Leandro et al, 2006). E, para que isso ocorra, adequados níveis de aminoácidos essenciais devem estar presentes no alimento.…”

The process of production of silage from fish waste may represent an important source of protein and energy for broilers, and rationally allocate this residue which is normally discarded erroneously. This work aimed to evaluate weight gain and morphometric parameters of broilers fed with feed made from fish viscera silage. For the composition of the experimental diet was counted with: 65.61 % of the silage fish waste, 30.39 % soybean meal, 2.20 % of calcined bone meal , 1.40 % soda and 0 , 30% vitamin mineral premix , in order to provide levels mixture of 19.2 % CP 0.898 % Ca, 0.528% P disp. and 3874 kcal kg- 1 of EB. However, during the experimental period the broilers they had died. In another experiment involving non-nutrient additives, but using the same source of silage, had same result. It is suspected that the level of conservation of raw material can be related to the case on the basis of having the potential to produce biogenic amines.

“…8 e 9A, observa-se maior massa corporal nos machos em todo o período estudado (P≤0,01), semelhante a resultados de outros experimentos, em que os valores de peso e ganho de peso das fêmeas foram sempre mais baixos que os dos machos (Leandro et al, 2006;Longo et al, 2006). Portanto, visando acompanhar a tendência internacional com relação às exigência de tamanho, a massa corporal pode ser garantida pela sexagem dos animais, pois fêmeas e machos atingem pesos vivos diferentes no final do ciclo produtivo.…”

RESUMOAvaliou-se o efeito do ambiente de produção sobre o desempenho produtivo e respostas fisiológicas de frangos de corte de marca comercial sexados, machos e fêmeas. Os frangos foram criados em duas alas separadas no interior de um galpão comercial com sistemas de ventilação convencional e nebulização. O ambiente produtivo foi avaliado por meio do índice de temperatura do globo negro e umidade, da intensidade de ruído e do nível de iluminância. A avaliação dos animais foi feita por meio das respostas fisiológicas − frequência respiratória, temperatura retal, temperatura da pele e temperatura da pena − e produtivas − ganho de peso semanal, massa corporal e mortalidade. Os machos apresentaram desempenho produtivo superior às fêmeas (P<0,05). A massa corporal média dos machos foi 214,6g maior que a das fêmeas aos 35 dias de vida, a qual se igualou à massa corporal dos machos somente aos 38,47 dias de vida. As respostas fisiológicas não se relacionaram com o ambiente.Palavras-chave: frango de corte, ambiente termoacústico, iluminância, desempenho ABSTRACT
