发布时间：2019-01-03 06:41
【摘要】：通过对2002~2012年间公开发表于英文期刊的日粮中添加木聚糖酶后肉鸡1~21日龄和22~42日龄平均日增重(ADG)、平均日采食量(ADFI)和料重比(FG)数据进行Meta分析后发现,日粮中添加内切木聚糖酶可使肉鸡的平均日增重提高0.46(0.19~0.73)g/(d·只)(P0.05),料重比降低0.02(P0.05),但却存在显著(P0.05)的发表偏倚。
[Abstract]:The average daily gain (ADG),) daily intake (ADFI) and feed weight ratio (FG) of broilers were analyzed by Meta after adding xylanase to diets published in English journals in 2002 and 2012. The results showed that the average daily gain (ADG) of broilers was 1 ~ 21 days old and 22 ~ 42 days old, and the average daily feed intake (ADFI) and feed weight ratio (FG) data were analyzed by Meta. The average daily gain (ADG) of broilers was increased by 0.46 (0.19 ~ 0.73) g / (d) (P0.05) and the feed weight ratio was decreased by 0.02 (P0.05), but there was a significant (P0.05) publication bias.
