摘要
为探究稀土作为饲料添加剂对林麝(Moschus berezovskii)采食量、血液指标和粪便微生物的影响,选取12只年龄相同、体况良好的育成期林麝,随机分为2组,每组6只(3♀,3♂),对照组饲喂常规日粮,试验组饲喂常规日粮和稀土添加剂(150 mg/kg精补料),预饲期15 d,正试期25 d.结果表明:(1)添加稀土对林麝基础饲粮的采食量没有显著影响(p>0.05),但试验组树叶采食量和总采食量显著高于对照组(p<0.05).(2)添加稀土对林麝的体质量和体增质量没有显著影响(p>0.05).(3)添加稀土后林麝血清尿素(UREA)和总胆固醇(TCH)含量较对照组低(p<0.05),其他血液指标差异不显著(p>0.05).(4)试验组和对照组粪便微生物的Chao1指数、Simpson指数、Shannon指数和基于ANOSIM分析的Beta多样性没有显著差异(p>0.05).由此可见,本试验条件下添加稀土提高了林麝采食量,降低了血清UREA和TCH含量,对林麝体质量和粪便微生物多样性没有显著影响.
Abstract
This experiment was conducted to investigate the effects of rare earth on feed intake,blood parameters and fae-cal microbiota of forest musk deer(Moschus berezovskii).Twelve forest musk deers with the similar age and good health were randomly divided into two groups(trial and control),six for each group(3♀,3♂).The trial group was fed conventional diet and rare earth additive(150 mg/kg concentrate supplement).The experiment had 15 days pre-feeding period and 25 days formal period.(1)There was no significant effect of adding rare earth on the feed intake of basal diet(p>0.05),but the intake of leaf and total ration in the trial group were significantly higher than the control group(p<0.05).(2)The addi-tion of rare earth had no significant effect on body weight and weight gain of forest musk deer(p>0.05).(3)The contents of UREA and TCH in serum of forest musk deer in trial group were lower than those of control group(p<0.05),but other blood indexes were not significantly different(p>0.05).(4)There was no significant difference between the trial and control groups in Chao1 index,Simpson index,Shannon index and Beta diversity of ANOSIM results(p>0.05).It is concluded that the addition of rare earth increased feed intake of forest musk deer and decreased serum UREA and TCH levels,but had no significant effect on forest musk deer's body weight and faecal microbial diversity.
