Enzymatic complex for broilers fed on a diet containing different levels of Distiller Dried Grains with Solubles.

The objective of this research was to evaluate the effect of the inclusion of an enzyme complex (carbohydrases, proteases and phytase) in diets formulated with DDGS inclusion levels (0 to 30%) in parameters of performance, nutrient digestibility and serum biochemical profile of broiler chickens from 1 to 42 days old. The inclusion of DDGS impaired the performance characteristics in all phases, but broilers feeding with diets containing up to 8% DDGS improves the percentage carcass. Addition of the enzyme complex improved feed conversion by 3.

Effects of processing, particle size and moisturizing of sorghum-based feeds on pellet quality and broiler production.

Objective: This study aimed to assess the effect of pelleted and expanded sorghum-based feeds prepared with different moisture levels and particle size of ingredients on metabolizable energy, ileal digestibility of amino acids and broiler performance.

Methods: The experiment was performed with 720 male broiler chicks of the Cobb strain, with treatments of six replications, with 15 birds each; they were arranged in a completely randomized design and 2×2×2 factorial scheme (pelleted or expanded feed processing, 0.8% or 1.
