摘要

A total of 192 one-old-day broilers were equally divided into six groups to find the effect of different levels (5, 10, 15, 20 and 25%) of substituted barley on the performance and intestinal histology (villus length, width, crypts depth and number of goblet cells). One group served as a control while the other groups were treated with 5, 10, 15, 20 and 25% barley. Results revealed that higher level (20 and 25%) of barley depressed the weight gain and feed conversion ratio and enhanced the feed intake (25%). On the other hand, in 20 and 25% level of barely, the villus height and width decreased significantly without affecting the crypts depth and number of goblet cells. It was concluded that higher level of barley level may be harmful for the growth of performance mainly due to its antinutritional substances
