【摘要】：本文旨在考察妊娠后期母猪饲粮添加酒石酸泰万菌素(TT)与植物精油(PEO)对其生产性能、免疫功能和乳成分的影响。试验选用24头体重相近的3~4胎次"长×大"繁殖母猪,随机分为3组:1)对照组:基础饲粮;2)TT组:基础饲粮+100 mg/kg TT;3)PEO组:基础饲粮+200 mg/kg PEO。每组8个重复,每个重复1头猪。试验期为妊娠第96天至断奶。结果显示,饲粮添加TT和PEO可改善母猪生产性能;与对照组和TT组相比,PEO组死胎率分别降低了71.43%和53.33%(P0.05),断奶存活率分别提高了1.17%和1.60%(P0.05),木乃伊率较对照组降低了50.00%(P0.05);PEO组母猪分娩第1、14和21天、TT组母猪分娩第21天血清免疫球蛋白(Ig)A含量均显著高于对照组(P0.05);PEO组母猪分娩第14天乳清Ig G、Ig M含量也显著高于其他2组(P0.05),同时其分娩第21天乳清Ig G含量显著高于对照组(P0.05);PEO组母猪分娩第21天乳脂含量显著高于对照组(P0.05)。综上所述,饲粮添加TT和PEO均能在不同程度上改善母猪生产性能与免疫功能,但与TT相比,PEO效果更好,具有替代TT在妊娠母猪上应用的潜力。
[Abstract]:The purpose of this study was to investigate the effects of tevanosin tartrate (TT) and plant essential oil (PEO) on the production performance, immune function and milk composition of sows fed in late pregnancy. Twenty-four sows with similar body weight were randomly divided into 3 groups: control group (n = 3): basal diet group (n = 2) TT: basal diet 100 mg/kg TT3) PEO group: basal diet 200 mg/kg PEO. There were 8 replicates in each group and 1 pig in each group. The trial period was from the 96 th day of pregnancy to weaning. The results showed that dietary supplementation of TT and PEO could improve the performance of sows. Compared with the control group and TT group, the stillbirth rate of PEO group decreased by 71.43% and 53.33% (P0.05), the weaning survival rate increased by 1.17% and 1.60% (P0.05), and the mummy rate decreased by 50.00% (P0.05) compared with the control group. The content of globulin (Ig) A was significantly higher than that of the control group (P0.05). The content of Ig G G M in whey of the PEO group was also significantly higher than that of the other two groups on the 14th day of labor (P0.05), and the content of Ig G in the whey on the 21st day of delivery was significantly higher than that in the control group (P0.05) on the 21st day of delivery. The content of milk fat was significantly higher than that of the control group (P0.05). To sum up, dietary supplementation of TT and PEO could improve the performance and immune function of sows to some extent, but compared with TT, PEO had better effect and had the potential to replace TT in pregnant sows.
