Effect of substituting yellow corn by triticale grains on productive performance of two broiler strains [electronic resource].

Includes references.

The objective of this experiment was to evaluate the efficiency of substituting (0, 25, 50. 75 and 100%) yellow corn by triticale grains with or without a commercial enzyme supplementation (Avizyme 1500) on productive performance, mortality rate and economical efficiency of broiler chickens. A total number of 700 one-day old unsexed broiler chickens from two strains Ross and Cobb (350 each) were divided into ten treatments for each cross (35 birds each), each treatment contained 5 replicates of 7 birds. Results indicated that substitution of yellow corn by triticale grains at different levels caused significant increase in live body weight at 42 days of age and live body weight gain during the period from 5-42 days for the Ross strain, while the differences were insignificant for Cobb strain. Feed intake was significantly' increased by substitution of yellow corn by triticale in the Ross broiler diet from 0% to 100%. Cobb broiler fed diet containing 100% triticale had the lowest feed intake while, those fed diets containing 50% triticale had higher FI. Enzyme supplementation significantly affected feed intake for the two strains. Inclusion of triticale in the Ross and Cobb broiler diets at different levels had insignificant effects on feed conversion. crude protein conversion, caloric conversion ratio and performance index.
