Abstract: Abstract:We investigated the effects of a combination of protease, xylanase, and phytase in maize-or sorghum-based diets for broilers. Two experiments were conducted with male chicks randomly distributed in a 3 × 2 factorial arrangement with three replacement levels of maize with sorghum (0%, 50%, and 100%) with or without enzymes. In the first trial, 1152 chicks were allotted to 36 floor pens to determine performance, relative organ weight, and litter moisture. A second trial was performed with 150 and 120 ch… Show more

“…In the treatment containing sorghum + 9% RASM, feed conversion values were similar to those obtained for corn-based diets. Sorghum contains tannins (low level), phytate, kafirin, and polyphenols that may have anti-nutritional effects (McCuistion et al, 2018), causing lower digestibility and nitrogen retention rates (Pasquali et al, 2017) relative to cornbased diets. However, these effects may have been mitigated by a lower ratio of sorghum and higher oil level relative to corn-based diets.…”

“…Nalle et al [6] suggested that it is possible to include high levels of lupine in diets for broilers by removing the hull and/or by using enzymes to degrade NSP. The use of exogenous enzymes such as xylanases and proteases in diets for broilers to attenuate nutrient encapsulation by NSP, such as arabinoxylans, and to increase protein degradation has recently been investigated [8]. We hypothesized that inclusion of dehulled lupine seed as the main protein source plus enzymes in broiler diets does not affect productive performance, size of digestive organs or welfare-related variables.…”

“…Supplementation of monogastric feed with exogenous enzymes has become routine to support measures of performance, as well as to mitigate the effects of anti-nutrients, most commonly phytate, non-digestible starches and proteins, and polyphenolic compounds ( Cowieson et al, 2006 ). Polyphenols are well-established anti-nutrients and antifeedants, particularly to monogastrics, and routinely cause reduced feed intake and weight gain, increased FCR (reduced efficiency), and enzyme inhibition ( Bravo, 1998 ; Cadogan and Finn, 2010 ; Pasquali et al, 2016 ; Alu’datt et al, 2018 ).…”
