不同中草药复方制剂对云岭黑山羊生产性能及免疫功能的影响

本试验研究了日粮中添加不同中草药复方制剂对云岭黑山羊生产性能及免疫功能的影响。试验选用健康无病、出生日期和体重相近的云岭黑山羊成年母羊120只,随机分为4组,每组30只,其中1个对照组只饲喂基础日粮不添加制剂;3个试验组分别按精料的1.2%添加自制复方紫锥菊提取物、四君子散和强壮散。预试期为7 d,第1~2 天添加试验量的1/4,第3~4 天添加试验量的1/3,第5~6 天添加试验量的2/3,第7 天添加试验量(精料量的1.2%);正试期为60 d,分别于正试期第0,30,60 天清晨对所有试验羊进行空腹称重并准确记录,并测定其总增重和平均日增重,计算料重比,进而分析其经济效益;于试验结束当天从每组中分别随机选择10只羊进行空腹颈静脉采血,进行血液生理生化指标的测定。结果表明,1)复方紫锥菊提取物组云岭黑山羊成年母羊的总增重和平均日增重最高,分别为6.17 和0.103 kg,分别较对照组提高了17.97%和6.18%;2)复方紫锥菊提取物组的料重比最低为1.96∶1.00,分别比对照组、四君子散组、强壮散组降低了7.09%,17.76%,45.01%,且与强壮散组差异显著 (P＜0.05);3)复方紫锥菊提取物组羊的盈利额最大,每只羊每天可创效益4.25元,而对照组每只羊每天可创效益3.58元,比对照组提高了15.76%,而四君子散组、强壮散组的盈利额则低于对照组;4)复方紫锥菊提取物可显著提高血液中的红细胞数和红细胞压积(P＜0.05),对白细胞数也有一定的提高作用(P>0.05),白细胞数较对照组提高了3.98%,四君子散亦可显著提高血液中的红细胞数(P＜0.05);5)复方紫锥菊提取物和强壮散可显著提高血清总蛋白和球蛋白含量(P＜0.05),较对照组血清总蛋白分别提高了11.65%和12.33%,球蛋白分别提高了27.25%和22.16%;6)各试验组中胆固醇含量均有所降低(P>0.05),复方紫锥菊提取物、四君子散、强壮散组分别比对照组降低了15.25%,2.12%,6.78%;7)强壮散和复方紫锥菊提取物均可提高血清中免疫球蛋白G的含量,分别比对照组提高了3.5和1.3倍。综合研究表明,复方紫锥菊提取物对云岭黑山羊的生长有一定促进作用,并可增强其免疫功能,提高养羊的经济效益。

Effect of different Chinese herbal compound on production performance and immune function of Yunling black goat

Effect of different Chinese herbal compound on production performance and immune function of Yunling black goat was evaluated in this study.120 adult ewes with close birth date and weight were randomly divided into 4 groups by 30 per group,in which one was chosed as the control group and the other 3 groups as treatments(adding 1.2% of concentrate with Echinacea extract compound,four gentlemen powder and strong powder in the feed,respectively).The experiment included preliminary trial period(7 d,1/4 of trial amount was added in the first 2 d,1/3 of it was added in the second 2 d,2/3 of it was added in the third 2 d,all trial amount was added in the 7th day) and trial period(60 d).All adult ewes were weighed fastingly on the morning of the 0,30th and 60th day,recorded the total gain,average daily gain,and calculated the feed conversion ratio and the economic effectiveness.1) In groupⅠ,the total weight gain and average daily weight gain were both the highest,with the value of 6.17 and 0.103 kg,which were 17.97% and 6.18% higher than that of control group respectively,but those of other 2 treatments were both lower compared to the control group;2) In groupⅠ,the feed conversion ratio was 1.96: 1,and it was lower than that of the control group and groupⅡ by 7.09%,17.76% and significantly(P<0.05) lower than that of group Ⅲ by 45.01%;3) In groupⅠ,the net profit of sheep was the largest with the price of 4.25 Yuan/(d·ewe) which was 15.76% higher compared to the profit 3.58Yuan/(d·ewe) gained from the control group;4)The number of red blood cell(RBC) and hematocrit(HCT) apparently increased in groupⅠ(P<0.05),the number of white blood cell(WBC) was higher by 3.98% than that of the control group,and the number of RBC also increased greatly in groupⅡ(P<0.05);5) The serum total protein(TP) and globulin(GLB) of groupⅠand Ⅲ were significantly higher than those of the control group(P<0.05),also the Serum TP was 11.65% and 12.33% higher than that of the control group respectively,and the GLB of the two groups increased by 27.25% and 22.16%;6) The serum cholesterol(CHO) of the 3 treatments was less than that of the control group(P>0.05),and compared to the control group,the CHO content of groupⅠ,Ⅱand Ⅲ decreased by 15.25%,2.12% and 6.78%,respectively;7) In groupⅠand Ⅲ,the immunoglobulin G(IgG) content was higher than that of other groups,especially higher than that of the control group by 3.5 and 1.3 times respectively.In conclusion,the Echinacea extract compound can promote production performance and the immune function of Yunling black goat,and it also increases the economic benefit.
