摘要
为研究哺乳期湖羊羔羊补喂鞣花酸对其生长发育及血液生化指标的影响,试验选择出生(10±3)d、平均体重(5.41±1.71)kg的哺乳羔羊18只,随机分为3组,每组6只,分别为对照组、试验Ⅰ组和试验Ⅱ组。在相同的饲养管理条件下,对照组不做任何处理,试验Ⅰ组每天补喂15 mg/kg BW鞣花酸,试验Ⅱ组每天补喂30 mg/kg BW鞣花酸,进行45 d的饲养试验。结果显示:(1)试验Ⅰ组和试验Ⅱ组哺乳羔羊总增重和平均日增重均高于对照组,分别提高了15.03%、14.99%、3.79%和3.74%。(2)血清总蛋白,试验Ⅰ组比对照组和试验Ⅱ组提高了5.19%和22.01%;白蛋白,试验Ⅰ组比对照组和试验Ⅱ组提高了17.54%和13.74%;血清总胆固醇,试验Ⅰ组比对照组和试验Ⅱ组提高了17.61%和9.52%。(3)各组酶活力无显著差异,但谷丙转氨酶比谷草转氨酶,试验Ⅰ组比对照组和试验Ⅱ组提高了51.20%和55.10%。(4)哺乳羔羊血浆中钙、磷、镁离子浓度和血清直接胆红素各组之间无显著性差异。但试验Ⅰ组羔羊血浆中总胆红素显著高于对照组,比对照组提高了56.28%。综上所述,在本试验条件下,羔羊日粮中添加15 mg/kg BW鞣花酸可提高其总增重、平均日增重,血浆氮、糖脂和矿物质离子浓度代谢。羔羊日粮中添加30 mg/kg BW鞣花酸可提高血浆酶活力。综合分析,给哺乳期羔羊补喂15 mg/kg BW鞣花酸效果较好。
The purpose of this experiment was to study the effects of supplying ellagic acid on the growth and blood biochemical indexes of lactation Hu lambs.Eighteen suckling lambs with birth date(10±3)d and average body weight of(5.41±1.71)kg were randomly divided into three groups:control group(n=6),experimental groupⅠ(n=6)and experimental groupⅡ(n=6).Under the same feeding and management conditions,the control group did not do any treatment.Group I was fed with 15 mg/kg BW ellagic acid every day,and group II was fed with 30 mg/kg BW ellagic acid every day for 45 days.The results showed that:(1)The total weight gain and average daily gain of suckling lambs in groupⅠand groupⅡwere higher than those in the control group,which increased by 15.03%,14.99%,3.79%and 3.74%,respectively.(2)Serum total protein in groupⅠincreased by 5.19%and 22.01%compared with control group and groupⅡ;albumin in groupⅠincreased by 17.54%and 13.74%compared with control group and groupⅡ;serum total cholesterol in groupⅠincreased by 17.61%and 9.52%compared with control group and groupⅡ.(3)There was no significant difference in enzyme activity among each group,but glutamic pyruvic transaminase was higher than glutamic oxaloacetic transaminase,and the activity of glutamic pyruvic transaminase in groupⅠwas 51.2%and 55.10%higher than that in control group and groupⅡ.(4)There was no significant difference in plasma Ca,P,Mg concentration and serum direct bilirubin among suckling lambs.However,the total bilirubin in plasma of lambs in group I was significantly higher than that in the control group,which was 56.28%higher than that in the control group.To sum up,under the conditions of this experiment,the addition of 15 mg/kg BW ellagic acid to lamb diet could improve its total weight gain,average daily gain,plasma nitrogen,sugar and lipid and mineral ion metabolism.The addition of 30 mg/kg BW ellagic acid to lamb diet could increase the activity of plasma enzyme.Comprehensive analysis showed that feeding 15 mg/kg BW ellagic acid to
