中草药渣对断奶仔猪生长、肠道菌群和免疫的影响

在体重约7 kg的28日龄断奶仔猪基础日粮中分别添加0.5%,1.0%,1.5%的中草药渣,与对照组比较,日增重分别增加5.04%(P>0.05),12.28%(P<0.05)和7.72%(P<0.05),料重比分别降低6.01%(P<0.05),9.29%(P<0.05)和7.10%(P<0.05),腹泻率分别降低29.95%(P<0.05),46.19%(P<0.01)和34.52%(P<0.05)。添加1.0%的中草药渣组与对照组比较,肠道内乳酸杆菌、双歧杆菌数分别增加47.33%(P<0.05)和83.95%(P<0.01),大肠杆菌、梭菌数分别下降41.35%(P<0.05)和29.93%(P<0.05);血清TP,ALB,GLO含量分别提高13.37%(P<0.05),12.40%(P<0.05)和51.07%(P<0.01),BUN含量降低15.84%(P<0.05),血清GPT,GOT,ALP活性分别提高9.45%(P<0.05),20.10%(P<0.05)和31.85(P<0.05);血清IgG,IgA,C3含量分别提高16.56%(P<0.05),18.31%(P<0.05)和33.33%(P<0.05)。日粮添加中草药渣对血清CHO,TG3,HDL,LDL,VLDL,IgM,C4含量无显著影响(P>0.05)。

Effects of Chinese herb residues on growth performance, intestinal microflora, and immune function of weaning piglets

One hundred and forty-four weaning piglets were selected to study effects of adding Chinese herb residues in diet on growth,intestinal microflora and immune function.The results showed that addition of 0.5%,1.0%,and 1.5% Chinese herb residues in base diet increased daily gain by 5.04%(P>0.05),12.28%(P<0.05),and 7.72% (P<0.05),respectively,decreased feed gain ratios by 6.01%(P<0.05), 9.29%(P<0.05),and 7.10%(P<0.05),respectively,and reduced diarrhea rates 29.95%(P<0.05),46.19%(P<0.01) and 34.52%(P<0.05),respectively as compared with the control group.Addition 1.0% Chinese herb residues increased the amounts of colonic Lactobacilli and Bifidobacteria by 47.33%(P<0.05) and 83.95%(P<0.01),respectively.It also decreased Colibacillus and Clostridia by 41.35%(P<0.05) and 29.93%(P<0.05),respectively,and increased the contents of TP,ALB and GLO in serum by 13.37%(P<0.05),12.40%(P<0.05) and 51.07%(P<0.01),respectively.It decreased BUN by 5.84%(P<0.05) and increased GPT,GOT and ALP levels by 9.45%(P<0.05),20.10%(P<0.05) and 31.85%(P<0.05),respectively.It increased the concentrations of IgG,IgA,and C3 in serum by 16.56%(P<0.05),18.31%(P<0.05) and 33.33%(P<0.05),respectively.The results also indicated that addition of Chinese herb residue did not affect the contents of CHO,TG3,HDL,LDL,VLDL,IgM and C4 in serum.
