ABSTRACT The experiment aimed to evaluate the effects of supplementing a standard broiler diet, formulated based on corn and soybean meal (CSBM), with two levels of an exogenous enzyme (EZ) cocktail (0 and 0.05%), under two dietary metabolizable energy (ME) levels – normal (positive control, PC) and low (negative control, NC). From 0 to 35 d, 288 Ross 308 chicks were distributed across four treatments with 12 replicates of six chicks each. Growth performance was evaluated during the starter, grower, […]

ABSTRACT This study aimed to investigate the effects of xylanase (Xyl) individually or in combination with B. subtilis and B. licheniformis associated or not with yeast cell wall in pig diets with a reduction of 100 kcal/kg of metabolizable energy (ME) content. Pig performance, bone parameters, intestinal morphometry, and bioeconomic indices were evaluated. A total of 75 pigs (25 females and 50 barrows; 25.02±3.21 kg) obtained from crossing Large White × Landrace were used. The experimental design consisted of randomized […]
