| 摘 要： | 旨在研究不同剂量有机酸型酸化剂替代抗生素对断奶仔猪生长性能的影响。试验选择健康、日龄相近、初始体重为（8.70±0.20）kg的杜×长×大杂交断奶仔猪144头,随机分为4组（分别为对照组,处理1、2、3组）,每组4个重复,每个重复9头仔猪。对照组饲喂基础日粮,处理1组在基础日粮上添加25 mg/kg金霉素和50 mg/kg喹烯酮,处理2组和处理3组在基础日粮上分别添加0.4%和0.7%有机酸型酸化剂（甲酸、乳酸、柠檬酸和富马酸）,试验共进行14 d。试验结果表明,处理1、2、3组相比于对照组断奶仔猪的日增重显著提高（P<0.05）,分别提高20.60%、7.90%和15.30%;与对照组相比,处理1、2和3组料重比显著降低（P<0.05）,分别降低13.20%、7.60%和13.35%;与对照组相比,处理1、2和3组腹泻率显著降低（P<0.05）,分别降低16.11、11.11和15.91个百分点;与对照组相比,处理1、2和3组日均采食量没有显著差异（P>0.05）;处理1组和处理3组对断奶仔猪日增重和料重比的改善程度接近。结果表明,通过添加有机酸型酸化剂能改善断奶仔猪的生长性能,添加高剂量的有机酸型酸化剂能达到金霉素和喹烯酮组合使用的效果。

| Abstract: | The study was conducted to investigate the effects of replacing antibiotics using different dosages of organics acidifier on growth performance of weaning piglets. A total of 144 Duroc×Landrace×Yorkshire crossbred weaning piglets with similar initial average body weight （8.70±0.20）kg] and days of age were randomly divided into 4 groups, including control group and experimental groups of 1, 2 and 3. There were 4 repeats in each group and 9 piglets in each repeat. The control group was fed with basal diet,the experimental group 1 fed the basal diet supplemented with 25 mg/kg duomycin and 50 mg/kg quinocetone, and the experimental groups of 2 and 3 received dietary supplementation of 0.4% and 0.7% organic acidifier composed of formic acid, lactic acid, citric acid and fumaric acid, respectively. The experimental period lasted for 14 days. The results showed that compared to the control group, the daily gain of the experimental groups of 1, 2 and 3 were significantly （P<0.05） elevated by 20.60%, 7.90% and 15.30%, respectively; the feed to gain ratio of the experimental groups of 1, 2 and 3 were significantly （P<0.05） reduced by 13.20%, 7.60% and 13.35%, respectively;the diarrhea rate of the experimental groups of 1, 2 and 3 were 16.11%, 11.11% and 15.91% lower than that of the control group, and significant （P<0.05） differences were observed; there were no significant （P>0.05） difference in average daily feed intake between the control group and the three experimental groups; the experimental group 3 had the similar effect on improving daily gain and feed to gain ratio of the weaning piglets with experimental group 1. In conclusion, dietary supplementation of organic acidifier improved the growth performance of weaning piglets, and the higher dosage of organic acidifier had the similar effect with the combinative use of duomycin and quinocetone. |
