复方中草药制剂对母猪生产性能及哺乳仔猪生长性能、免疫功能及健康水平的影响

Effects of compound Chinese herbal preparations on production performance of sow and growth performance,immune function and health level of suckling piglets

试验旨在研究复方中草药制剂对母猪生产性能及哺乳仔猪生长性能、免疫功能及健康水平的影响,选择30头胎次相同且产期接近的母猪随机分为两组,每组3个重复,每个重复5头母猪。在基础饲料与饲养环境相同的情况下,对照组投喂基础日粮,试验组在基础日粮中添加1%的复方中草药制剂。投喂期42 d,于妊娠母猪临产前14 d开始至哺乳母猪产后28 d为止。仔猪断奶后跟踪观察母猪和断奶仔猪至仔猪60日龄。结果显示:试验组仔猪断奶成活率为99.33%,相比对照组提高了4.89%(P<0.05)。试验组母猪平均发情间隔天数为5.5 d,较对照组缩短了30.38%(P<0.05);试验组乳房炎发病率为5.7%,较对照组降低了44.66%(P<0.05)。试验组仔猪28日龄体重、1~28日龄平均日增重比对照组提高了16.14%、20.00%(P<0.05),腹泻率比对照组降低了60.83%(P<0.05)。试验组仔猪60日龄体重、29~60日龄平均日增重相比对照组提高了18.49%、19.23%(P<0.05),腹泻率及出现其他疾病的次数分别比对照组降低了51.04%、64.66%(P<0.05)。与对照组相比,试验组仔猪免疫球蛋白G (IgG)、免疫球蛋白M (IgM)、血清免疫球蛋白A (IgA)含量分别提高了29.06%、26.54%、21.05%(P<0.05),白细胞介素-2 (IL-2)、白细胞介素-6 (IL-6)含量提高了13.63%、26.46%(P<0.05),总超氧化物歧化酶(T-SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性提高了6.48%、1.41%(P<0.05),丙二醛(MDA)含量降低了28.52%(P<0.05)。研究表明,复方中草药制剂可明显提高母猪的生产性能及健康状况,提高仔猪生长性能、免疫功能及健康水平。

This experiment was conducted to investigate the effects of compound Chinese herbal preparations on the performance of sows and the growth performance,immune function and health level of suckling piglets.Thirty sows with the same first parity and close perinatation were randomly divided into two groups with three replicates per group and five sows per replicate.The control group was fed the basic diet,and the experimental group was fed the basic diet with 1%compound Chinese herbal preparations.The feeding period lasted for 42 days,from 14 days before delivery to 28 days after delivery.Sows and weaned piglets were followed up to 60 days of age in piglets.The results showed that the weaning survival rate of piglets in the experimental group was 99.33%,which was increased by 4.89%compared with the control group(P<0.05).The average estrus interval of sows in the experimental group was 5.5 days,which was shortened by 30.38%compared with the control group(P<0.05).The incidence of mastitis in the experimental group was 5.7%,which was 44.66%lower than that in the control group(P<0.05).The body weight of piglets at 28 days of age and average daily gain from 1 to 28 days of age in the experimental group were 16.14%and 20.00%higher than those in the control group(P<0.05),and the diarrhea rate of piglets in the experimental group was decreased by 60.83%(P<0.05).Compared with the control group,the body weight at 60 days of age and the average daily gain at 29 to 60 days of age of piglets in the experimental group were 18.49%and 19.23%higher(P<0.05),and the diarrhea rate and the frequency of other diseases were reduced by 51.04%and 64.66%(P<0.05),respectively.Compared with the control group,the serum contents of immunoglobulin G(IgG),immunoglobulin M(IgM)and immunoglobulin A(IgA)of piglets in the experimental groups were increased by 29.06%,26.54%,and 21.05%,respectively(P<0.05).The contents of interleukin-2(IL-2)and interleukin-6(IL-6)were increased by 13.63%and 26.46%(P<0.05),and the activities of total superoxide dismutase(T-SOD)and glutathione peroxidase(GSH-Px)were increased by 6.48%and 1.41%(P<0.05).The content of malondialdehyde(MDA)was decreased by 28.52%(P<0.05).The study indicates that the compound Chinese herbal preparations can obviously improve the production performance and health status of sows,and improve the growth performance,immune function and health level of piglets.
