Abstract

This experiment was conducted to investigate the effects of different levels of vitamins and trace minerals recommendations in broiler breeder hens on growth performance, immunity response and bone parameters in the Progeny. 520 broiler breeder hens aged 50 weeks were used for 12 weeks in a completely randomized design with 13 treatments and 4 replications, with 10 hens in each replication, and one rooster for every 10 hens. The experimental treatments included two dietary nutrient recommendation based on Ross 308 parent stock and 4th Brazilian tables for poultry, three levels of 100, 80, and 60 percent vitamins and trace minerals based on Ross recommendation, and two levels of 100, 80 vitamins and trace minerals based on Brazilian table recommendations'. Then, the progenies from each treatment were hatched and penned separately and raised for 35 days under standard conditions. The level of vitamins and minerals consumed in the diet of progeny was 50% of the Ross-broiler recommendations ( 2021). The results showed that the weight of the first and third weeks, average daily weight gain from 1 to 35 days and feed conversion ratio, were significantly affected by the experimental diets (P<0.05). Blood serum levels of M and T immunoglobulins in the of progenies were showed significant values in the experimental diets (P<0.05). The effect of experimental treatments on the femoral parameters was significant (P<0.05). Overall, the best response based on immune response was observed in the 3rd treatment, and based on feed conversion ratio (1-35 days), in the 13th treatment.
