Effects of dietary fat type and different levels of vitamin E on performance and some of eggs characters of broiler breeder.

摘要: The study carried out to evaluate the effects of fat type and different levels vitamin E on performance some egg characters broiler breeding hens. 90 breeder hens (Ross 308 strain) at 27 week age were fed in a 2 ×3 factorial trial (4% Canola oil Tallow with 0, 75 150 mg/kg E) an 8 weeks period. At end experiment significant differences not found body weight, feed intake, conversion rate, number weight eggs, laying percentage hatchability variables between treatments. difference eggs E, linoleic linolenic acids (P<0.01), total oleic (P<0.05) significant, while arachidonic stearic acid there no difference. results showed that fatty profile significantly influenced (mainly acids) by diet. In conclusion, it was could be effective content, source do limit absorption, although they may increase its degradation gastrointestinal tract. However increasing had affect it's deposit content groups (P<0.05).
