摘要:
选用福建黄兔与太行山兔杂交后代30日龄的幼兔100只,分成5组,每组20只。试验组日粮中分别添加大米草草粉5%、10%、15%和20%,试验期50 d。研究大米草对肉兔生长性能和血液生化指标的影响。结果表明:日粮中加入大米草草粉15%时,可降低饲料单价11.58%(P0.05)和增重成本11.63%(P0.05),提高平均只毛利6.79%(P0.05),而采食量不受影响。随着大米草添加量的增加,血清总蛋白和白蛋白均呈上升趋势,以添加大米草草粉15%最高,但各组之间差异不显著(P0.05);甘油三酯和胆固醇含量均呈下降趋势,与对照组相比添加大米草草粉15%和20%的处理组甘油三酯含量分别下降了10.13%和11.39%,差异显著(P0.05);胆固醇含量分别下降了8.48%和10.30%,差异显著(P0.05)。4种血清酶含量各处理组之间差异不显著(P0.05)。
Abstract:
One hundred 30-days old,Fujian yellow譚aihangshan crossed rabbits were divided into 5 groups for the experiment.They were fed with feed containing 0%,5%,10%,15% or 20% of Spartina anglica meal for 50 days.Effects of S.Anglica in diets on the growth performance and blood biochemical parameters of the rabbits were determined.The results showed that(a) addition of 15% S.anglica cut the unit feed cost by 11.58%(P0.05) and the weight gain cost by 11.63%(P0.05),which resulted in an improved gross profit by 6.79%(P0.05),without apparent effect on the animal's feed intake;(b) the serum total protein and albumin increased with increasing S.anglica content in the diet;(c) the serum total protein and albumin was the highest when 15% of S.anglica was used,but no significant difference among the groups(P0.05) was observed;(d) the concentrations of triglyceride and cholesterol declined with increasing S.anglica in the feed;(e) the concentrations of triglyceride were 10.13% and 11.39% and those of cholesterol 8.48% and 10.30% lower in the treatments of 15% and 20% of S.anglica,respectively,than the control(P0.05);and,(f) no significant difference on the activities of 4 serum enzymes among groups(P0.05) was found.
