日粮中不同配比棉仁饼对种用太湖母鹅饲用价值的研究

A STUDY ON FEEDING VALUE OF COTTONSEED MEAL AND ITS TOXICITY IN BREEDING TAIHU FEMALE GEESE

选用175羽8月龄健康太湖种鹅,对日粮中不同配比棉仁饼的饲用价值进行了试验。结果表明,不含棉仁饼的组1孵化率极显著高于含11%棉仁饼的组5(p<0.01),显著高于含棉仁饼9%的组4(p<0.05),高于含棉仁饼5%的组2和7%的组3,但差异不显著(p>0.05)。棉仁饼比例占日粮5%～11%时对产蛋量和饲料利用率均未见不良影响。器官组织中 FG 含量随棉仁饼用量增加而升高。含棉仁饼11%的组5血清中 GOT 活性极显著高于其它组(p<0.01)。

175 feathers of 8-month's old Taihu breeding geese were selected and divided into 5 groups with a female:male ratio of 1:6.The 5-month's studies were conduted to dertermine effects of cottonseed meal on productivity of Taihu female geese,free gossypol content in the body and activity of GOT in serum.The results showed that dietary cottonseed meal supplmentation dcreased egg hatchability significantly in group 5(P<0.01 )and group 4(P<0.05),but not significantly in group 2 and 3(p>0.05),however egg pro- duction and feed efficiency were unaffected.The amount of free gossypol in the liver of geese increased with the increase of dietary cottonseed meal proporation.Activity of GOT in serum in group 5 was sinificantly higher than other grouops(P<0.01)
