摘　　要：文章旨在探究微生物发酵饲料对育肥猪生长性能、养分消化率及经济效益的影响。试验将240头健康的外三元杂交猪(均重19.38±0.51 kg)随机分为4个处理,每处理6个重复,每个重复10头。试验日粮分别向各阶段基础日粮中添加0%、2%、4%和8%的发酵饲料。试验为期102 d。结果发现,8%的发酵饲料组育肥猪的末重较对照组显著提高7.96%(P <0.05),平均日增重较对照组显著提高9.75%(P <0.05),平均日采食量较对照组显著提高3.54%(P <0.05),料重比较对照组显著降低5.66%(P <0.05)。4%和8%的发酵饲料组仔猪的干物质(DM)消化率显著提高(P <0.05);4%和8%的发酵饲料组仔猪的粗纤维(CF)消化率显著提高(P <0.05),9%的发酵饲料组能量表观消化率显著提高(P <0.05)。4%和8%发酵饲料组育肥猪总增重分别提高3.83和7.98 kg(P <0.05),各组毛利润分别为412.86、412.50、431.84和480.02元(P <0.05)。结论 :8%的发酵饲料对育肥猪的促生长作用最佳。To explore the effects of microbial fermented feed on growth performance,nutrient digestibility and economic benefit of finishing pigs.A total of 240 healthy foreign Yuan hybrid pigs(average weight 19.38±0.51 kg)were randomly divided into 4 treatments with 6 replicates per treatment and 10 pigs per replicate.The experimental diets were supplemented with 0%,2%,4%and 8%fermented feed,respectively.The experiment lasted for 102 days.The results showed that:Compared with control group,the final weight of finishing pigs in 8%fermented feed group was significantly increased by 7.96%(P<0.05),the average daily gain was significantly increased by 9.75%(P<0.05),the average daily feed intake was significantly increased by 3.54%(P<0.05),and the ratio of feed to gain in control group was significantly decreased by 5.66%(P<0.05).DM digestibility of piglets in 4%and 8%fermented feed groups was significantly increased(P<0.05).The CF digestibility of piglets in 4%and 8%fermented feed groups was significantly increased(P<0.05),and the energy apparent digestibility in 9%fermented feed group was significantly increased(P<0.05).The total weight gain of finishing pigs in 4%and 8%fermented feed groups was increased by 3.83 and 7.98 kg(P<0.05),respectively,and the gross profit of each group was 412.86,412.50,431.84 and 480.02 yuan(P<0.05),respectively.Conclusion:8%fermented feed has the best growth promotion effect on finishing pigs.
