Özet
This study conducted at the Poultry field of Animal Science Department, Faculty of Agricultural
Sciences, University of Sulaimany to investigate the Impact of Enzymes Supplementation on
Performance of Broiler Chickens Fed on Diets Containing Corn and Wheat. Bird naturally output enzymes for digesting nutrients. However, bird does not have enzymes to moulder fiber perfectly and that enzymes secretion by salivary glands is very limited, especially to digesting high ratio of starch. So we need to add enzymes (α- Amylase and Xylanase) in the feed to aid digestion. The influence of enzyme supplementation on performance and digestibility in broiler chicks was examined for the diet containing corn and wheat with different levels of enzyme, While the diet containing corn and wheat, And adding enzymes to the diet of broiler chickens resulted Significant (P≤0.05) increases in live body weight, weight gain, feed conversion and carcass weight, The best results for the traits included in this study were recorded by supplementing diet of broiler chickens with enzymes at the level of 0.04 % (T3, T6, and T9).
The experiment was conducted during the period from March 7th, 2017 to April 17th, 2017 by
using 378 Ross 308 broiler chicks, one-day-old. Chicks were allocated to nine treatments of three
replicates per group; each group constitutes 14 chicks, 42 chicks pertreatment group.
