不同养殖设施对反季节种鹅生产性能的影响OA

This study aimed to investigate the effects of three kinds of goose house facilities on the production performance of off-season geese,namely,regular cleaning of feces on the ground(Mode Ⅰ),no cleaning of feces on the net bed rearing(Mode Ⅱ)and frequent cleaning of feces on the net bed rearing(Mode Ⅲ).Three fully enclosed goose houses with different facility configurations were selected.Each house contained 1,800 breeding geese,which were divided into 6 groups of 300 geese each with a male to female ratio of 1∶5.The production performance indexes such as feed intake,laying rate,fertilization rate and hatching rate of geese were statistically analyzed under the premise of the same breeding,feed,environmental control and feeding management measures.The results showed that:(1)The feed intake of Mode Ⅲgeese(228.2 g/d)was higher than that in the other two facilities(P<0.05).The mortality and culling rate in Mode Ⅱwas significantly higher than that in Mode Ⅰ and Mode Ⅲ(P<0.05).While no significant difference was observed between Mode Ⅰ and Mode Ⅲ(P>0.05).(2)In the early laying period the laying rate of geese in Mode Ⅰ was significantly higher than that in Mode Ⅱ(P<0.05),and the fertilization rate of eggs in Mode Ⅲ was significantly higher than that in Mode Ⅱ(P<0.05).(3)During the peak laying period,the laying rate in Mode Ⅲ was significantly higher than that in Mode Ⅱ(P<0.05),and Mode Ⅲ was highly significantly higher than that in Mode Ⅰ(P<0.01),and the fertilization rate and hatching rate in Mode Ⅲ were significantly higher than that in Mode Ⅰ(P<0.05).(4)In the late laying period,all the indexes of Mode Ⅲ were significantly higher than those of Mode Ⅱ(P<0.05),and the indexes of laying rate were highly significantly higher than those of Mode Ⅰ(P<0.01),and the fertilization rate was significantly higher than those of Mode Ⅰ(P<0.05).Conclusion:Mode Ⅲ is beneficial to keep off-season geese healthy and give full play to the production performance.
