Feeding program with different dietary crude protein and metabolizable energy levels, for broilers

[摘要] Two trials were conducted to evaluate four different nutritional plans with different energy (ME) and protein (CP) levels, nominated PN1 (highest levels), PN2 (medium), PN3 (low) and PN4 (lowest) in starter, grower and finisher periods of broiler raising. The performance, carcass and parts yield and economic analyses were evaluated in male (Trail 1) and female (Trail 2) broilers. The experimental design consisted of 4 treatments and 4 replicates with 880 chickens, randomized into 16 floor pens (55 birds/pen). When necessary, we used Tu
