تأثیر مکمل آنزیمی در جیره‌های بر پایه گندم و تریتیکاله بر عملکرد و خصوصیات دستگاه گوارش جوجه‌های گوشتی

In order to study the effect of corn, Ghods wheat, Falaat wheat, and triticale with or without enzyme addition on perormance and digestive tract characteristics, an experiment was carried out by using 288 male broiler chickens in a compeletly randomized design with 4*2 factorial arrangement for 57 days. Enzyme addition significantly decreased both feed conversion ratio of chickens fed Ghods wheat and triticale, and weight gain of chickens fed Ghods wheat. Growth performance of chickens fed Ghods wheat with enzyme was not significantly different compared with corn without enzyme. Enzyme addition decreased ileum relative weight of chickens. Gizzard and proventriculus of chickens fed Falaat wheat and triticale were heavier than those of other treatments. According to the results, enzyme supplementation showed positive effect on triticale and especially Ghods wheat based diets.
