Óleo-resina de copaíba sobre as características seminais de galos

Abstract

In the poultry industry breeding programs contributed to greater feed efficiency and rapid growth in one animal. Associated nutritional deficiencies can negatively interfere with reproduction, so it is necessary to give importance to the nutritional quality of the diet of males. The aim of this study was to evaluate the effect of supplementation of oleoresin of copaiba (Copaifera sp.) In roosters diet on seminal characteristics 40 semi-heavy roosters aged 40 weeks were used, housed in individual boxes, receiving water ad libitum and fed the experimental diets for 6 weeks. The experimental design was completely randomized with two treatments and six replications. Treatments consisted of two experimental diets: T1 - control diet without the addition of oil-resin copal; T2 control diet with added on top of copaiba oil resin, which was homogenized in 25 kg feed, the amount of 3.68 grams of oleoresin copaiba (25 mg oleoresin / bump / day) as diets were based on corn and soybean meal, and formulated to meet the nutritional requirements and isonutritives. The following variables of fresh semen were evaluated: volume, motility, concentration, membrane integrity, acrosome and DNA, sperm penetration test. None of the characteristics was significantly affected by the treatments (P> 0.05). These results indicate that the evaluated reproductive variables were not influenced by the addition on top of the oilresin copaiba, however, the values are in agreement with the reference in terms of reproductive performance of breeding roosters.
