The experiment was conducted to evaluate the best feeding program post peak egg production for broiler breeders. Cobb broiler breeders (3168 females and 352 males) were distributed in a randomized experimental design with four treatments and eight replicates per treatment, with 99 females and 11 males per replicate. The evaluated programs were: Program 1 – Reduction 1 g of feed/bird/day/week for each drop of 0.5 points of the egg mass. Program 2 – Reduction of 1 g of feed/bird/day/week post […]

With the objective to evaluate two feeding programs (4 and 3 phases), on the performance and carcass yield of two commercial strains (Hubbard and Arbor Acres), 1,600 1-d chicks were used, 800 of each strain. A completely randomized design, in a 2 x 2 x 2 (program x strain x sex) factorial arrangement, with four replicates, was used. During the period from 1 to 46 days period, no effects were verified due either to programs or strains on weight gain […]
