摘  要：
本试验旨在研究微生物蛋白酶水解豆粕对1~21日龄肉鸡生长性能和养分消化率的影响。选择1日龄科宝母雏336只,随机分为4组,即对照组、试验Ⅰ、Ⅱ和Ⅲ组。对照组为玉米—豆粕型基础日粮,试验Ⅰ、Ⅱ和Ⅲ组分别以5%、10%和15%酶解豆粕替代对照组中等量的普通豆粕。试验结果表明,与对照组相比,试验组显著提高了肉鸡采食量(12%~21%)和增重(8%~16%)(P<0.05),降低料重比(3%~7%)(P<0.05);试验组对干物质、粗蛋白质、能量、钙和磷的消化率也具有显著的提高作用(P<0.05);各试验组之间,生产性能和干物质、粗蛋白质、钙消化率差异显著(P<0.05),但能量和磷的消化率差异不显著(P>0.05)。因此,豆粕经酶解改善了其蛋白质的营养价值,肉仔鸡日粮添加酶解豆粕可以提高肉鸡的生长性能和养分消化率。

摘  要：
The objective of this study was to investigate the effect of microbial protease hydrolyzed soybean meal on the growth performance and nutrient digestibility of 1 to 21-day-old broilers.A total of 336 female Cobb broilers were allocated into 4 treatments,including control group,experimental Ⅰ,Ⅱand Ⅲ group.Control diet was based on corn-soybean meal,and microbial protease hydrolyzed soybean meal was used to replace common soybean meal at 5%,10%,15% in experimentalⅠ,Ⅱand Ⅲ group,respectively.Results showed that experimental groups increased feed intake by 12% to 21% and body weight gain by 8% to 16%(P<0.05),and decreased ratios of feed to gain by 3% to 7%(P<0.05);and also improved the digestibility of dry matter,crude protein,energy,calcium and phosphorus of broilers(P<0.05),compared to the control group.There were significant differences among experimental groups in growth performance and the digestibility of dry matter,crude protein and calcium(P<0.05),but not for energy and phosphorus digestibility(P>0.05).The results suggested that soybean meal treated with microbial protease can improve the nutritional value of soybean protein and the growth performance and nutrient digestibility of broilers.
