灭活植物乳杆菌 仔猪 生长性能 血液生化指标 腹泻率
试验主要研究灭活植物乳杆菌对仔猪生长性能、血液生化指标及腹泻率的影响。选用45头28日龄的健康杜×长×大三元杂交断奶仔猪，对照组饲喂基础饲粮，试验Ⅰ组在基础饲粮中添加0.3 g/kg天蚕素抗菌肽，试验Ⅱ组在基础饲粮中添加0.3 g/kg灭活植物乳杆菌。结果表明，试验Ⅰ组与对照组相比平均日增重（ADG）提高了15.56%（P＜0.05），腹泻率降低了7.3%（P＞0.05）；试验Ⅱ组与对照组相比ADG提高了26.67%（P＜0.05），料重比（F/G）降低了13.73%（P＜0.05），腹泻率降低了56.92%（P＜0.05）。试验Ⅰ组与对照组相比大肠杆菌数量降低了37.25%（P＜0.05），沙门氏菌的数量降低了75.07%（P＜0.05）；试验Ⅱ组与对照组相比大肠杆菌数量降低了40.43%（P＜0.05），沙门氏菌的数量降低了90.03%（P＜0.05），乳酸菌数量提高了74.59%（P＜0.05）。与对照组相比，试验Ⅰ组和试验Ⅱ组免疫球蛋白G含量均显著提高（P＜0.05），分别提高了34.35%和60.31%；与对照组相比，试验Ⅰ组和试验Ⅱ组的血样中免疫球蛋白A、免疫球蛋白M、总蛋白、白蛋白含量都略有所提高的趋势，但差异不显著（P＞0.05）；与对照组相比，试验Ⅱ组与对照组相比血样中葡萄糖含量提高了15.70%（P＜0.05），尿素氮含量降低了42.70%（P＜0.05）。由此可见，在基础日粮中添加灭活植物乳杆菌，对于仔猪具有良好的饲喂效果，可改善仔猪生长性能，降低仔猪腹泻率，改善仔猪健康。%This experiment was conducted to investigate the effects of inactivated Lactobacillus plantarum on growth performance,blood biochemical indices and diarrhea rate of piglets.Forty-five 28-days-old healthy Dukes×landrace×large hybrid weaned piglets were fed a basal diet in control group,and 0.3 g/kg cecrosin antimicrobial peptide was added to the basal diet in trial group Ⅰ,and 0.3 g/kg inacti-vated Lactobacillus plantarum was added to the basal diet in trial group Ⅱ.The results showed that compared with the control group,the ADG of experimental group Ⅰ increased by 15.56%(P<0.05),and the diarrhea rate decreased by 7.3%(P>0.05);compared with the control group,the trial group Ⅱ showed a 26.67%increase in ADG(P<0.05),a 13.73%decrease in F/G(P<0.05),and a 56.92%decrease in diarrhea rate(P<0.05).Compared with the control group,the number of Esch-erichia coli in trial group Ⅰ decreased by 37.25%(P<0.05),and the number of Salmonella decreased by 75.07%(P<0.05);compared with the control group,the number of Escherichia coli decreased by 40.43%(P<0.05),the number of Salmonella decreased by 90.03%(P<0.05),and the number of lactic acid bacte-ria increased by 74.59%(P<0.05)in trial group Ⅱ.Compared with the control group,the levels of immu-noglobulin G in trial group Ⅰ and trial group Ⅱ were significantly increased(P<0.05),with an increase of 34.35%and 60.31%,respectively;Compared with the control group,there was a slight increase in the levels of immunoglobulin A,immunoglobulin M,total protein,and albumin in the blood samples of trial group I and trial group Ⅱ,but the difference was not significant(P>0.05);Compared with the control group,the GLU content in the blood samples of trial group Ⅱ group increased by 15.70%(P<0.05),while the UN content decreased by 42.70%(P<0.05).It can be seen that adding inactivated plant lacto-bacilli to the basic diet has a good feeding effect on piglets,which can improve their growth performance,reduce their diarrhea rate,and improve their health.
