枸杞多糖对生长獭兔营养物质表观消化率及氮代谢的影响
|
摘要
试验旨在研究枸杞多糖(lycium barbarum polysaccharide,LBP)对生长獭兔营养物质消化率、氮代谢的影响。试验选择体重相近的60 d断奶獭兔64只(公母各半),随机分为4组(每组16个重复,每个重复1只),对照组饲喂基础饲粮,试验组分别在基础饲粮基础上添加0.1%、0.2%、0.3%的LBP,预饲期5 d,正试期7 d。结果表明:在饲粮中添加LBP可以不同程度地提高生长獭兔营养物质表观消化率和氮代谢能力,但差异未达显著水平,推荐添加量为0.2%。
The purpose of this study was to study the effects of lycium barbarum polysaccharide on nu-trient utilization and nitrogen metabolism in growing rex rabbits. Select 64 weaned rex rabbits of simi-lar body weight for 60 d(male and female in half) with similar body weight were randomly divided into4 groups(each group of 16 replicates, each one replicate). The control group was fed with basic diet,while the experimental groups were added 0.1%, 0.2% and 0.3% LBP on the basis of basal diet. Pretrial period was 5 d and the trial period was 7 d. The results showed that: adding LBP to diets couldimprove the apparent digestibility of nutrients and nitrogen metabolism of rex rabbits in varying de-grees, but the differences were not significant, so the recommended LBP adding level was 0.2%.
