Efficacy of Carbohydrases Derived from Trichoderma longibrachiatum in Wheat- and Barley-Based Diets on Performance and Fermentation of Carbohydrates in the Intestine of Broilers

Abstract

Jamroz, D., Orda, J., Wiliczkiewicz, A. and Skorupinska, J. 2001. Efficacy of carbohydrases derived from Trichoderma longibrachiatum in wheat- and barley-based diets on performance and fermentation of carbohydrates in the intestine of broilers. J. Appl. Anim. Res., 19: 61–72.

Starbro broiler chickens were fed on diets (starter/grower) differing in the kind of cereals: 49/56% wheat (W), 49/56% barley (B) or 25/28% wheat and 25/28% barley (W+B), with or without supplementation of granulated. enzyme complex derived from Trichoderma longibrachiatum. Performance, carcass characteristics, length of intestinal segments and concentrations of fermentation products in different parts of the intestine were evaluated. The effects of the enzyme supplementation were higher in chickens fed diets containing wheat or wheat and barley. The production of short chain fatty acids as a result of non-starch polysaccharides degradation was not consistently influenced either by the kind of cereal or by the supplementation with carbohydrases.
