Características do trato digestivo, metabolizabilidade e retenção de nutrientes em frangos de corte alimentados com complexo enzimático

ABSTRACT The objective was to evaluate the digestive tract characteristics, metabolizability and nutrient retention of broilers fed diets supplemented with enzyme complex (EC). To evaluate the characteristics of the digestive tract 600 female Cobb 500 birds were used, distributed in a completely randomized design, with 5 inclusion levels of the EC (0; 100, 200, 300 and 400 g/ton) and 6 replicates of 20 birds each. To evaluate the metabolizability and the retention of nutrients 200 female Cobb 500 birds at 15 days of age were used, distributed in a completely randomized design with 5 levels of ...
