【摘要】 本试验旨在研究日粮单宁水平对育成期雄性梅花生长发育、角基萌发和初角茸生长的影响。选用24头体况相近的育成期雄性梅花鹿,随机分为4组,每组6头,采用单因素随机分组设计。对照组饲喂不添加单宁的基础日粮,Ⅰ、Ⅱ、Ⅲ组在基础日粮中分别添加1%、2%、4%单宁,试验期140d。结果表明,Ⅱ组梅花鹿体重、体高平均日增长显著高于对照组(P<0.05),各组间体长、管围平均日增长差异均不显著(P>0.05);与对照组相比,Ⅰ、Ⅱ、Ⅲ组梅花鹿角基萌发时间早;Ⅰ组梅花鹿初角茸左右支茸长均高于对照组和Ⅱ、Ⅲ组,其中Ⅰ组梅花鹿初角茸右支长茸长显著大于Ⅲ组(P<0.05),Ⅰ、Ⅱ、Ⅲ组梅花鹿初角茸左、右支的重量均显著高于对照组(P<0.05)。综上所述,日粮中添加适宜单宁能促进梅花鹿的生长发育、提前角基萌发时间,同时提高初角茸的产量。更多还原

【Abstract】 This experiment was conducted to study the effects of dietary tannins levels on growth,pedicle initiation and primary velvet antler growth of young male sika deer(Cervus Nippon).Twenty four 7-month-old male sika deer with similar body condition were allocated into four groups with six per group,in a single-factor randomized complete block design.The control group was fed with basal diets without tannin and group Ⅰ,Ⅱ,Ⅲ was fed with diets adding 1%,2%,4%tannin respectively,the experiment lasted for 140 d.The resuits showed that the group fed with 2%tannins gained significantly more daily growth in body weight and height(P < 0.05) than the control group.Differences of other indexes between four groups were not significant(P > 0.05).The pedicle initiation time of the experimental group was earlier than the control group.The length of both branch from group Ⅰ were higher than the other groups,and the right branch of group I were significantly higher than group Ⅲ(P < 0.05).The weight of primary velvet antler from experimental group were significantly higher than the control group(P < 0.05).It is concluded that feeds added tannin can promote the growth development,pedicle initiation and the production of primary velvet antler in sika deer.更多还原
