【摘要】 本试验旨在研究羽绒采收对浙东白鹅绒用性能、生长性能及血清生化指标的影响。选用120只同批饲养、体重相近的120日龄浙东白鹅,随机分成对照组和试验组,每组6个重复,每个重复10只。对照组仅在试验末期(45d)采绒1次,试验组分别在试验初期(1d)和试验末期(45d)各采绒1次。试验期45d。结果表明,羽绒采收可促进鹅羽绒生长,提高饲料转化效率,同时也对鹅机体产生短时间的应激。羽绒采收4d后血清总蛋白(TP)、白蛋白(ALB)、球蛋白(GLB)、葡萄糖(GLU)、钙(Ca)、磷(P)含量较羽绒采收前1d呈显著性变化(P<0.05);血清谷草转氨酶(AST)活性在羽绒采收4d后基本恢复到羽绒采收前水平,差异不显著(P>0.05);血清尿素氮(BUN)含量及转肽酶、谷丙转氨酶(ALT)、碱性磷酸酶(ALP)活性在羽绒采收前后则无显著性变化(P>0.05)。综上所述,120日龄浙东白鹅羽绒采收在生产中具有可行性,同时应加强采绒鹅1周内的饲养管理。更多还原

【Abstract】 In order to study the effect of defeathering on feather performance,growth performance and serum biochemical indexes of Zhedong White geese.A total of 120 120-day-old Zhedong White geese were randomly divided into control group and experimental group.The control group was defeathered only at the end of the experiment(45d),while the experimental group were defeathered at the beginning(1d)and the end of the experiment(45d),respectively.The trail lasted for45 days.The results showed that defeathering could promote the growth of feather and improve the feed conversion efficiency.Meanwhile,it could bring stresses syndrome to geese in a short time.There were significant differences in the serum level of TP,ALB,GLB,GLU,Ca and P 4d after defeathering compared with 1dbefore defeathering(P<0.05).There was no significant difference in the serum activity of AST 4dafter defeathering(P>0.05).Serum level of of BUN and serum activity of transpeptidase,ALT and ALP were not significantly changed before and after defeathering(P>0.05).In conclusion,it’s feasible to defeather in 120-day Zhengdong White geese.At the same time more attention should be paid to the feeds and managements during the first week after defeathering.更多还原
