【摘要】：通過(guò)對(duì)2002~2012年間公開(kāi)發(fā)表于英文期刊的日糧中添加木聚糖酶后肉雞1~21日齡和22~42日齡平均日增重(ADG)、平均日采食量(ADFI)和料重比(FG)數(shù)據(jù)進(jìn)行Meta分析后發(fā)現(xiàn),日糧中添加內(nèi)切木聚糖酶可使肉雞的平均日增重提高0.46(0.19~0.73)g/(d·只)(P0.05),料重比降低0.02(P0.05),但卻存在顯著(P0.05)的發(fā)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.
