摘 要：
[目的]在小天鹅放养初期饲喂纳豆芽孢菌剂,研究纳豆芽孢菌剂消除小天鹅转群应激的临床效果。[方法]在转群小天鹅精饲料中加入纳豆芽孢菌剂,纳豆芽孢菌剂为精料量的10%,观察小天鹅的精神状态、体态行动、喙的颜色、羽毛色泽及成活率等。[结果]饲喂纳豆芽孢菌剂16 d后,小天鹅的体质、粪便、采食量等指标显著改善,圈养及外放后未见死亡。[结论]纳豆芽孢菌剂能起到改善小天鹅转群应激反应和降低死亡率的作用。

摘 要：
[Objective] The aim was to study eliminating groupshift stress effect of Bacillus subtilis natto to Cygnus columbianus by adding Bacillus subtilis natto in feed in the initial stocking. [Method]In the initial stocking,adding Bacillus subtilis natto in feed with amount of concentrated feed 10%,the mental state,body weight,body condition action,beak color,plumage and survival rate of Cygnus columbianus was observed.[Result]After feeding Bacillus subtilis natto 16 days,body constitution,feces,feed intake and other clinical indicators of Cygnus columbianus were significantly improved,and was no death in captivity and outside.[Conclution]Bacillus subtilis natto can eliminate groupshift stress effect to Cygnus columbianus and reduce mortality.
