摘要:
This study aimed to evaluate the use of complexed trace minerals to amino acid in broiler breeder feeding evaluating performance, incubation variables and performance of progeny. The study was divided in three trials: exp. 1. broiler breeders performance, exp. 2. incubation and exp. 3. chickens performance. In the exp. 1 two hundred sixty broilers breeders of lineage Cobb Avian 48 (240 females and 20 males) were used. The variables evaluated were egg production and egg mass, feed conversion for egg mass and per dozen eggs, egg weight and specific gravity. In the exp. 2 it was determined rate of hatching, hatchability and fertility. In the exp. 3, it was evaluated the performance of chicks born from incubations. In the exp. 1, there was no interaction between treatment and period (P>0.05) for egg production, egg mass, feed conversion for egg mass and per dozen eggs, egg weight and specific gravity of eggs. However, there was effect (P<0.05) of the period for all variables mentioned above. In the exp. 2, hatching rate, fertility and hatchability did not show significant difference (P<0.05). Regarding the performance of broilers, in the exp. 3 there was no significant difference (P<0.05). Supplementation with complexed trace minerals to amino acids does not influence the performance of breeders, incubation variables and progeny performance.
