Abstract

In Ecuadorian Poultry Company “AVESCA”C.A, the effect of Cantaxantina utilization was evaluated and 25-Hidroxi-D3, over the reproductive parameters in roosters males of line COBB 500. The experimental units were modelated under at random design with four treatments, in base the addition of Cantaxantina and 25-Hidroxi-D3, in different dose, with six repetitions and a size of experimental unit of 25 birds. The results point that by effect of Cantaxantina and 25-Hidroxi-D3 addition, in a level of 0,5 kilos per ton of food (T1) it is manifested an appropriate volumetric (83,17 μL) and testicular weight (36,92g). The microscopical evaluation of semen shows that to feed the roosters reproducers with 0,5 kg/tn of Cantaxantina and 25-Hidroxi-D3 it is reported the best motility (4,48 over 5 of reference) and force (89,53%), therefore in covered the percentage of fertility (93,89%) and reduced of sperm anomalies (17,17%), as well as the best corporal weight of male (3392g). With the addition to the reproducers of 0,5 kg of Cantaxantina and 25-Hidroxi-D3, in the births registered in incubators, a relevant increase is observed, according to sale detail and monitoring post-natal, it is evidenced that the little chickens born of treatment with 0,5 of Cantaxantina and 25-Hidroxi-D3 (T1), shows a great feeding conversion and fast weight gain, generating most acceptance by the market, and over all a mayor economical profitability, because the relation cost-benefit was of 1,33 or profitability of 33%
