Abstract: | Objective] The aim was to study eliminating groupshift stress effect of Bacillus subtilis natto to Cygnus columbianus by adding Bacil-lus 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. |
