摘要: [目的]研究日粮中添加蜜蜂肽对断奶仔猪生长性能、腹泻率及养殖经济效益的影响。[方法]将80头体重相近的21日龄杜×长×大三元杂交断奶仔猪随机分为4组(对照组及试验Ⅰ组~Ⅲ组),每组2个重复,每个重复10头。对照组饲喂基础日粮,试验Ⅰ组~Ⅲ组基础日粮中分别添加200、400、600 mg/kg的蜜蜂肽。预饲期7 d,正饲期28 d。记录各组仔猪的试验初体重、试验末体重、采食量以及腹泻发生情况,计算平均日增重、平均日采食量、腹泻率,根据饲料成本和增重情况计算养殖经济效益。[结果]与对照组相比,试验Ⅰ组~Ⅲ组仔猪的试验末体重、平均日增重、平均日采食量均显著(P<0.05)提高,料重比和腹泻率均显著(P<0.05)降低。试验Ⅱ组和试验Ⅲ组仔猪的试验末体重、平均日增重、平均日采食量均显著(P<0.05)高于试验Ⅰ组,料重比和腹泻率均显著(P<0.05)低于试验Ⅰ组。试验Ⅲ组仔猪的试验末体重、平均日增重、平均日采食量、料重比及腹泻率均优于试验Ⅱ组,但差异不显著(P>0.05)。试验Ⅰ组~Ⅲ组的利润分别比对照组增加11.926、23.986、27.224元/头,试验Ⅲ组的养殖经济效益最好。[结论]日粮中添加蜜蜂肽可以提高断奶仔猪生长性能,降低腹泻率,增加养殖经济效益。综合来看,添加600 mg/kg的蜜蜂肽效果最好。

Abstract: [Objective] This study was conducted to assess the effects of dietary supplementation of honeybee peptide on growth performance, diarrhea rate and economic benefits of weaned piglets. [Method] A total of eighty 21-day-old crossbred (Duroc×Landrace×Yorkshire) weaned piglets with similar body weights were randomly allocated into four dietary treatment groups, including a control group and three experimental groups (Ⅰ-Ⅲ). There were two replicates in each group and ten piglets in each replicate. The piglets in control group fed a basal diet, and those in experimental groups Ⅰ-Ⅲ fed the same basal diets supplemented with 200, 400 and 600 mg/kg of a commercially available honeybee peptide, respectively. The feeding experiment consisted of a 7-day preparatory trial and a 28-day formal trail. The piglets were weighed at the beginning and at the end of the experiment. The feed intake and the number of piglets with diarrhea during the experiment were recorded. Subsequently, the average daily weight gain, average daily feed intake and diarrhea rate were calculated. In addition, the economic benefits were estimated according to the diet cost and weight gain of the piglets. [Result] Compared with the control group, the experimental groups Ⅰ-Ⅲ had significantly (P<0.05) elevated final weights, average daily weight gain and average daily feed intake, and had significantly (P<0.05) reduced feed to gain ratio and diarrhea rate. Compared with the experimental group Ⅰ, the experimental groups Ⅱ and Ⅲ had significantly (P<0.05) higher final weights, average daily weight gain and average daily feed intake, and had significantly (P<0.05) lower feed to gain ratio and diarrhea rate. The experimental group Ⅲ had superior final weights, average daily weight gain, average daily feed intake, feed to gain ratio and diarrhea rate to experimental group Ⅱ, while no significant (P>0.05) differences were observed. The individual profits of the experimental groups Ⅰ-Ⅲ were 11.926, 23.986 and 27.224 Yuan higher than the control group, respectively, and the best economic benefit was observed in experimental group Ⅲ. [Conclusion] Dietary supplementation of honeybee peptide has significant effects on improving growth performance, reducing diarrhea rate, and increasing economic benefit of the weaned piglets. The addition level of 600 mg/kg is recommended.
