高温季节小麦-豆粕型饲粮对育肥猪生长性能的影响

Effect of Wheat-Soybean Meal Feed on Growth Performance of Finishing Pigs in High Temperature Season

试验旨在研究高温季节未添加NSP酶的小麦-豆粕型饲粮对育肥猪生长性能的影响。2021年7月至10月在长顺县汇农种养殖基地选取92日龄平均初始体重为(45±2)kg的育肥猪48头,随机分成2组,每组4个重复,每个重复6头。对照组饲喂玉米-豆粕型饲粮,试验组饲喂小麦-豆粕型饲粮。预试期7 d,正试期为育肥四阶段饲养结束。结果表明:同对照组相比,试验组育肥猪平均日采食量(ADFI)、平均日增重(ADG)和育肥期料重比(F/G)无显著变化(P>0.05),但育肥二阶段、育肥三阶段及育肥期的头均饲料成本显著降低(P<0.05)。综上所述,高温季节小麦-豆粕型饲粮对育肥猪平均日采食量(ADFI)、平均日增重(ADG)及育肥期料重比(F/G)无显著影响,但能显著降低育肥猪头均饲料成本。

This experiment was conducted to study the effect of wheat-soybean meal feed without NSP enzyme on growth performance of finishing pigs in high temperature season.From July to October,2021,48 finishing pigs with an initial body weight of(45±2)kg at 92 d were selected from the Huinong lanting and breeding base in Changshun County,randomly divided into two groups,with four replicates in each group and six pigs in each replicate.The control group was fed corn-soybean meal feed,and the experimental group was fed wheat-soybean meal feed.The pre-tria period was seven days,and the trial period was the end of four-stage fattening.The results showed as follows:compared with the control group,there were no significant changes in the average daily feed intake(ADFI),average daily gain(ADG)and feed to gain ratio(F/G)of finishing pigs in experimental group(P>0.05),but can significantly reduce head average feed cost in the second,third,whole stages of fattening(P<0.05).To sum up,the wheatsoybean meal feed has no significant effect on the average daily feed intake(ADFI),average daily gain(ADG)and feed to gain ratio(F/G)of finishing pigs in high temperature season,but it can significantly reduce the average feed cost of fattening pigs.
