Abstract

Jamroz, D., Skorupiñska, J., Orda, J., Wiliczkiewicz, A. and Klünter, A.-M. 2001. Use of wheat, barley or triticale in feed for laying hens supplemented with carbohydrases derived from Trichoderma longibrachiatum. J. Appl. Anim. Res., 19: 107–116.

The objective of the present experiment was to determine the influence of different cereals (67% wheat, 66% barley or 70% triticale) in feed for laying hens supplemented with and without carbohydrases derived from Trichoderma longibrachiatum on laying performance, egg quality, digestibility and utilization of nutrients. In average of the 386 days of egg production the laying performance was 92.2, 92.0 and 91.2% in the wheat, barley and triticale diet, respectively. Egg production and feed conversion were similar for the diets containing different types of cereals. The addition of the enzyme product to the wheat diet and the barley diet improved the laying performance significantly by 3.2 and 3.0%. With regard to the type of cereal used in the diets, no differences in egg quality were observed.
