摘要/Abstract

摘要： 为了准确掌握大豆水解蛋白在断奶仔猪饲料中的适宜添加量和添加时期,选择健康、体重相近的杜长大三元杂交仔猪48头（14日龄,刚断奶,公、母各半）,将仔猪随机分为Ⅰ组、Ⅱ组、Ⅲ组3个组,其中,Ⅰ组作为对照组,饲料中不添加大豆水解蛋白;Ⅱ、Ⅲ组分别在饲料中添加3.0%和4.0%的大豆水解蛋白。预试期7 d,正试期28 d。结果表明,在试验的前3周,Ⅱ、Ⅲ组仔猪每周的平均体重和平均日增重都显著（P<0.05）高于对照组;在试验的第1周,Ⅱ、Ⅲ组的平均日采食量显著（P<0.05）高于对照组;在试验的前2周,Ⅱ、Ⅲ组的料重比显著（P<0.05）低于对照组;前3周,Ⅱ、Ⅲ组每周的腹泻率都较对照组显著（P<0.05）降低;整个试验期内,Ⅱ、Ⅲ组干物质和粗蛋白的利用率显著（P<0.05）高于对照组。综上所述,大豆水解蛋白能有效改善断奶仔猪的生产性能和营养物质的利用率,适宜添加量为3.0%,适宜添加阶段为15~42日龄。

Abstract: The objective of this study was to accurately determine the appropriate amount and period of adding soybean protein hydrolysate in the diet of weaned piglets. A total of 48 （half male and half female） 14-day-old, healthy and just weaned three-way crossbred piglets （Duroc×Landrace×Yorkshire） with similar weight were selected in this study. The experimental piglets were randomly assigned into the following three groups group Ⅰ was served as a control, in which no dietary supplementation of soybean protein hydrolysate was made; group Ⅱ and group Ⅲ were used as experimental groups, in which 3.0% and 4.0% of soybean protein hydrolysate were supplemented in the basal diet, respectively. The pretrial period was 7 days, and the formal trial period lasted for 28 days. The results showed that in the first three weeks of the experiment, the average week weight and average daily gain of piglets in group Ⅱ and group Ⅲ were significantly （P<0.05） higher than those in group Ⅰ; in the first week of the experiment, the average daily feed intake of group Ⅱ and group Ⅲ was significantly （P<0.05） higher than that in group Ⅰ; in the first two weeks of the experiment, group Ⅱ and group Ⅲ had significantly （P<0.05) lower feed to gain ratio compared with group Ⅰ; in the first three weeks of the experiment, group Ⅱ and group Ⅲ had significantly （P<0.05） lower diarrhea rate in each week than group Ⅰ; significantly （P<0.05） better performance in utilizations of dietary dry matter and crude protein were observed in group Ⅱ and group Ⅲ compared to group Ⅰ. The combined data suggest that the dietary supplementation of soybean protein hydrolysate can effectively improve the production performance and the utilization rate of nutrients in weaned piglets. The 3.0% of soybean protein hydrolysate is recommended to be supplemented in basal diet of weaned piglets from 15 to 42 days of age.
