Abstract

The present trial was carried on with the aim of evaluating the effect of the increasing levels of an enzymatic complex in diets with deactivated full-fat soybean on feed intake (FI), weight gain (WG) and feed:gain ratio (FG) of broilers from 1 to 24 days of age. 480 broilers from the Ross strain were used, allotted to
a completely randomized design, containing 4 treatments, 6 replicates, each one with 20 chicks. The chicks were housed in a conventional barn, divided in floor pens with wood shavings. Feed and water were fed ad libitum to broilers. The experimental diets were formulated based on corn, soybean meal and deactivated full-fat soybean, according to the nutritional levels used by the Brazilian Industry. The enzymatic complex (xilanase, â-glucanase, mannanase, pectinase and protease) was added in increasing levels of ; 25; 50 e 75 g/t of ration. The 50g/t enzymatic complex supply, in deactivated full-fat soybean diets increased the feed
intake in 3% and the weight gain in 2,5% comparing with the unsupplied diets. According to the regression analysis the best enzymatic complex addition level for weight gain and feed intake (1-42 days of age) on this experimental conditions was 45,94g/t and 49,30g/t of enzyme in the ration respectively. The enzymatic
complex addition level was close to 50 g/t.
