- Abstract
This experiment was carried out to evaluate the effect of the enzymatic complex addition and deactivated full-fat soybean particle size on performance of broilers in the period from 1 to 42 days of age. Four hundred and eighty male broiler chicks from the Ross strain were used, allotted to a completely randomized factorial scheme 2x2 (enzyme x particle size). The experimental diets were based on corn, soybean meal and (±1.5 mm or ±4.0mm) deactivated full-fat soybean, with or without enzyme. The enzymatic complex (xylanase, b-glucanase, mannase, pectinase and protease) was supplied in the dose of 50g t-1ration. The enzymatic complex addition increased (P=0.0531) the diet intake in 4% and the weight gain in 2.8% in the final period. The feed intake increased 3% in the final period and 2% in the total period in poultry that were fed with fine particle size diet. In the initial period, the chicks that ingested the coarse particle size diet had a 5% weight gain increase and had the greater feed rates. The addition of the enzymatic complex in diets with deactivated full-fat soybean improves the performance of chickens. The use of the soy with fine particle size (1,5mm) in the initial phases for chickens is not recommended.
