An experiment was conducted to evaluate the performance and composition of litter, tibia, liver and excreta of broiler chicks at different phases using different levels of available phosphorous (Pd) and the enzyme phytase. One thousand and two hundred one-day-Cobb-male chicks were used, distributed in a randomized complete design, using a 4 × 3 factorial arrangement, consisting of four available phosphorus levels and three phytase levels – 0, 500 and 1,000 FTU phytase/kg of diet with four replications of 25 birds […]

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 […]
