【摘要】：试验旨在研究饲粮粗纤维缺乏对57~84日龄扬州鹅生长性能、脏器指数和血清生化指标的影响,以研究粗纤维对鹅不可或缺的作用。选取20只56日龄体格健壮的扬州鹅公鹅,按照组间体重差异不显著(P0.05)的原则分为试验组和对照组,每组10只。试验组饲喂粗纤维水平为0%的纯合日粮,对照组饲喂粗纤维水平为6%的基础饲粮,试验期28 d。结果表明:(1)饲粮粗纤维缺乏显著降低了84日龄扬州鹅体重(P0.05),显著降低了57~84日龄扬州鹅的平均日增重(P0.05),显著提高了57~84日龄扬州鹅的料重比(P0.05);(2)饲粮粗纤维缺乏显著降低了57~84日龄扬州鹅血清淀粉酶活性(P0.05),而对其他血清生化指标没有显著影响(P0.05);(3)饲粮粗纤维缺乏显著降低了84日龄扬州鹅的肌胃指数(P0.05),而对心脏指数、肝脏指数、脾脏指数、胸腺指数、法氏囊指数和腺胃指数均没有显著影响(P0.05);(4)饲粮粗纤维缺乏会导致57~84日龄扬州鹅持续排稀便。综上所述,饲粮粗纤维缺乏通过抑制肌胃生长,降低血清淀粉酶活性,导致鹅的生长性能降低,鹅饲粮中需要添加适量水平的粗纤维才能保证正常的生长发育。
[Abstract]:The purpose of this study was to study the effect of crude fiber on the growth performance, organ index and serum biochemical index of Yangzhou goose aged 57-84, and to study the essential role of crude fiber on the goose. 20 56-day-old male geese were selected and divided into the test group and the control group according to the principle that the weight difference of the group was not significant (P0.05). The results showed that (1) The lack of crude fiber in the fed diet significantly decreased the body weight of Yangzhou goose at 84 days (P0.05). The average daily gain of Yangzhou goose was significantly decreased (P0.05), and the weight ratio of Yangzhou goose was significantly increased from 57 to 84 days (P0.05). (2) The lack of crude fiber in the fed diet significantly decreased the activity of serum amylase of Yangzhou goose (P. 05) at the age of 57-84 days. There was no significant effect on the biochemical indexes of the other serum (P0.05). (3) The lack of crude fiber in the fed diet significantly decreased the gastric index of the 84-day-old Yangzhou goose (P0.05), and the heart index, the liver index, the spleen index, the thymus index, There was no significant effect on the index of the bursa of Fabricius and the index of the glandular stomach (P0.05). (4) The lack of coarse fiber in the feed could lead to the continuous drainage of Yangzhou goose at the age of 57-84. To sum up, the lack of coarse fiber in the fed grain has the effect of inhibiting the growth of the muscle and the activity of the serum amylase, which leads to a decrease in the growth performance of the goose, and a proper amount of crude fiber is required to be added in the goose-fed grain to ensure normal growth and development.
