Resumo
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 peak production until the end of production period, regardless the percentage of the egg production. Program 3 - Reduction of 3 g of feed/bird/day/week, in the first week post peak production, 2 g of feed/bird/day/week in the second week and 1 g of feed/bird/day/week on the following weeks. Program 4 - Reduction of 5 g of feed/bird/day/week, in the first week post peak production, 3 g of feed/bird/day/week in the second week and 1 g of feed/bird/day/week on the following weeks. According to the results of feed intake per egg, the best program was the program 1, followed by programs 3, 2 and 4. It was recommended the program 1 for Cobb broiler breeders with peak egg production in the winter.
