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。

Abstract: 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.
