Effect of different feeding density on performance of rose 308 white broiler
The purpose of this experiment was to determine the effects of different feeding densities on the performance of Ross 308 white broilers.297 7-day-old broilers were randomly divided into 3 groups,group Ⅰ(13 broilers/m2),group Ⅱ(20 broilers/m2)and group Ⅲ(27 broilers/m2),with 9 replicates per group for 32 days.The results showed that the daily gain of broilers in group Ⅰwas significantly higher than that in group Ⅱ and Ⅲ(P＜0.05);Feed intake of broilers in groupⅠwas significantly higher thanthat in group Ⅱ and Ⅲ(P＜0.05);The feed-meat ratio of broilers in group Ⅰ,Ⅱ and Ⅲ was not significantly different,and the difference between groups was not significant(P＞0.05).Feeding density had little effect on the survival rate of broilers.Comprehensive analysis shows that 13 broilers/m2 is better under this test condition.
