益生菌、抗生素和小肽对仔猪生产性能的影响

Effect of Production Performance of Weaning Piglets by Probiotics,Antibiotics and Small Peptide

文章旨在研究在基础日粮中单独或联合添加益生菌、抗生素和小肽对断奶仔猪生产性能的影响。结果表明,与对照组相比,添加益生菌、抗生素和小肽日增重分别提高10.95%、13.01%和9.92%,饲料利用效率提高11.24%、12.36%和9.55%,仔猪腹泻率降低34.95%、51.46%和32.02%;与对照组相比,益生菌+抗生素组、益生菌+小肽组仔猪日增重分别提高13.69%和20.21%,饲料利用效率提高10.68%和13.48%,仔猪腹泻率降低33.99%和46.61%。因此,单独或联合添加能够提高断奶仔猪的生产性能,益生菌与小肽合用对仔猪生产性能存在一定的协同效应,而益生菌与抗生素合用未表现出协同效应。

To investigate effeets on the production performance of weaning piglets by probiotics, antibiotics and small peptide used separately or combined adding basal diet. The results showed that the group of adding probioties, antibiotics and small peptide increased daily gain 10.95% and 13.15% and 9.92%, improved feed efficiency 11.24% and 12.36% and 9.55%, reduced diarrhea rate of 34.95% and 51.46% and 32.02% than the control group; The group of probiotics＋antibiotics, probiotics＋small peptide respectively increased daily gain 13.81% and 20.18%, improved feed efficiency 10.68% and 13.48%, reduced diarrhea rate of 34.0% and 46.61% than the control group. The conclusion showed that probioties, antibiotics and small peptides adding alone or combined were improved the production performance. There was a synergistic effect adding combination of probiotics and small peptides, there was no synergistie effect adding combination of probiotics and antibiotics.
