Resumo: Feeding restriction is used for breeder broilers in order to limit the gain of corporal weight and to optimize their reproductive performance. It is necessary to moderate the rate of precocious growth through programs of feed restriction. This work aimed to evaluate the effects of feed restriction on the reproductive performance in breeder broilers males. The following treatments were evaluated: T1 = control; T2 = 6 days feeding and 1 day without feeding; T3 = 5 days of feeding and 2 day without feeding. 18 animals of the lineage Avian Farm were used. The parameters evaluated were: corporal weight, testicular weight, seminal characteristics of 6 animals per treatment at the age of 219 days. Randomized complete blocks were used to test the treatments effects. Significant differences were not observed (p > 0.05) among the treatments for corporal weight, testicular weight, mean weight gain, spermatic motility and vigor and total cells number. Spermatic concentrations were lower (p < 0.10) in the animals that received the treatments T1 and T3. The animals of T2 showed higher ( p < 0.05) seminal volume. The program of 6 days feeding and 1 day without feeding can be used in breeder broilers males of the lineage Avian Farm without affecting reproductive performance.

É necessário moderar a taxa de crescimento precoce por meio de programas de restrição alimentar. Este trabalho teve como objetivo avaliar o efeito da utilização da restrição alimentar sobre o desempenho reprodutivo em galos reprodutores de corte. Neste trabalho, foram avaliados os seguintes ratamentos: T1= controle; T2= 6 dias com alimentação e 1 dia sem alimentação; T3 = 5 dias com alimentação e 2 sem alimentação. Foram utilizados 18 animais da linhagem Avian Farm, avaliando-se o peso corporal, o peso gonadal e as características seminais de 6 animais por tratamento aos 219 dias de idade. O delineamento usado foi o de blocos casualizados (DBC). Não foram observadas diferenças (p > 0,05) entre os tratamentos sobre pesos corporal e onadal, motilidade e vigor espermáticos e número total de células. As concentrações espermáticas foram menores (p < 0,10) nos animais que receberam os tratamentos T1 e T3. Os animais do T2 apresentaram maior (p < 0,05) volume seminal. Entre as alterações morfológicas, apenas o número de alterações de cauda apresentou diferenças significativas entre os tratamentos, sendo o maior número observado nos animais que receberam 5 dias com alimentação e 2 dias sem alimentação. A restrição alimentar do tipo 6 dias de alimentação e 1 dia sem alimentação pôde ser utilizada em reprodutores de frangos de corte da linhagem Avian Farm sem afetar o desempenho reprodutivo.Editora da Universidade Estadual de Maringá2008-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/64310.4025/actascianimsci.v28i2.643Acta Scientiarum.
