The objective of the present study was to evaluate carcass and parts’ yield, abdominal fat deposition and breast and foot pad blisters of broilers reared under two lighting programs (nearly continuous or intermittent) in broilers houses with yellow and blue curtains. The experiment was conducted between June, 2004 and May, 2005. Six flocks were sequentially housed in four 12 × 10 m broiler houses divided into 4 pens with 200 birds each. The litter was reused six times or until […]

To evaluate the effect of probiotic (Lactobacillus sp.) associated with different crude protein (CP) levels on performance, CP nutritional requirements, carcass and cut yields of meat quails, a total of 2304 meat quails were distributed in a 2 × 4 factorial design (with and without probiotic and four CP levels – 15, 20, 25 and 30%), with two replications per treatment, repeated twice in time (two experimental periods), totalizing 32 experimental units. The addition of probiotic decreased the feed intake […]
