ABSTRACT This study aimed to evaluate the effects of thermal processing and different carbohydrate sources on performance, development of digestive organs, and pancreatic enzyme activity in broiler chicks during the pre-starter phase. The experiment was conducted in a completely randomized design with a 2 × 2 factorial arrangement (pelleting or extrusion processing, and corn or sorghum) and included six replicates of 15 chicks each. The experimental diets were provided only during the pre-starter period (1–7 d). From 8 to 21 […]

A total of 1440 male broiler chickens from 8 to 21 days old was assigned to two experiments to evaluate the physical form of diet, use of enzymes and nutritional levels of corn-soybean meal based diets. A completely randomized design as a 2 × 2 × 2 factorial scheme, two physical forms of diet (meal or crushed), with or without enzimatic complex (amylase, cellulase and protease) and two nutritional levels (95 or 100% of the recommendations), was used. In the […]
