摘要
文章旨在研究发酵豆粕(Fermented Soybean Meal,FSM)对育肥猪生长性能、养分消化率及屠宰性能的影响.试验选取初始体重(92.18±1.65)kg的杜长大育肥公猪 48 头,随机分为 2 组,每组 3 个重复,每个重复 8 头.参考育肥猪营养需要配制豆粕(Soybean Meal,SM)型基础日粮,SM组育肥猪饲喂基础日粮,FSM组育肥猪饲喂试验日粮(以 10%发酵豆粕等量替代基础日粮中的豆粕).预试期 7 d,正试期 35 d.结果表明:(1)与SM组相比,FSM组育肥猪平均日增重显著提高 12.86%(P＜0.05),料重比显著降低 7.78%(P＜0.05),结测体重有上升趋势(P＜0.10).(2)与SM组相比,FSM组育肥猪干物质、粗蛋白质消化率显著提高(P＜0.05).(3)与SM组相比,FSM组育肥猪胴体重、屠宰率显著提高(P＜0.05),宰前活重有上升趋势(P＜0.10).由此可见,以 10%发酵豆粕等量替代基础日粮中的豆粕能提高育肥猪的生长性能、养分消化率及屠宰性能.
Abstract
To investigate the effects of fermented soybean meal(FSM)on the growth performance,nutrient digestibility,and slaughter performance of fattening pigs.48 Duroc fattening male pigs with an initial weight of 92.18±1.65kg were selected and randomly divided into 2 groups,with 3 replicates in each group and 8 pigs in each replicate.According to the nutritional requirements of fattening pigs,a soybean meal(SM)type basic diet should be prepared.The SM group of fattening pigs should be fed with the basic diet,while the FSM group of fattening pigs should be fed with the experimental diet(replacing the soybean meal in the basic diet with 10%fermented soybean meal).The pre trial period is 7 days,and the main trial period is 35 days.The results showed that:(1)Compared with the SM group,the FSM group increased the average daily weight gain of fattening pigs by 12.86%(P＜0.05),and the feed to weight ratio decreased by 7.78%(P＜0.05).The measured body weight showed an upward trend(P＜0.10).(2)Compared with the SM group,the FSM group significantly increased the digestibility of dry matter and crude protein in fattening pigs(P＜0.05).(3)Compared with the SM group,the FSM group significantly increased the carcass weight and slaughter rate of fattening pigs(P＜0.05),and there was an upward trend in live weight before slaughter(P＜0.10).It can be seen that replacing soybean meal in the basic diet with 10%fermented soybean meal can improve the growth performance,nutrient digestibility,and slaughter performance of fattening pigs.
