| 摘 要： | 旨在研究5种比例的牧站1号王草益生菌发酵饲料对黑猪生产性能及养殖效益的影响。选择体重相近、健康状况良好的二元杂黑猪180头,随机分为6组,每组3次重复,每个重复10头。对照组饲喂基础日粮,试验Ⅰ组、Ⅱ组、Ⅲ组、Ⅳ组、Ⅴ组分别在基础日粮中添加10%、20%、30%、40%、50%牧站1号王草益生菌发酵饲料。饲喂试验预试期7 d,正试期60 d,计算并比较各组试验猪平均日增重、平均日采食量、腹泻率、屠宰率及养殖毛利润。试验结果表明：试验组与对照组比较,Ⅲ组试验猪平均日增重差异不显著（P>0.05）,其他试验组试验猪平均日增重差异显著（P<0.05）,最高为Ⅱ组（865.24 g/头）,高于对照组23.24%,其次是Ⅰ组（839.33 g/头）,高于对照组19.55%,最低为Ⅴ组（552.51 g/头）,低于对照组21.31%;平均日采食量最大为Ⅴ组（3.35 kg/头）,最小的为对照组（2.30 kg/头）,各试验组与对照组比较,差异显著（P<0.05）;屠宰率方面,Ⅰ组、Ⅱ组差异不显著（P>0.05）,Ⅲ组、Ⅳ组、Ⅴ组差异显著（P<0.05）,屠宰率随着牧站1号王草益生菌发酵饲料添加量的增加呈降低趋势,最高为对照组,最低为Ⅴ组;毛利润最高的为Ⅱ组（21 259.0元）,最低的为Ⅴ组（10 325.7元）。育肥黑猪日粮中添加 20%牧站1号王草益生菌发酵饲料生产性能及经济指标影响效果最佳。

| Abstract: | This study was conducted to assess the effects of dietary supplementation with 5 different rates of probiotic fermentation feed prepared with Kinggrass No.1 on production performance and feeding economic benefit of black pig.A total of 180 healthy binary hybrid black pigs with similar weight were selected and randomly divided into 6 groups with 3 replicates for each group and 10 individuals for each replicate.The control group was fed with the basal diet,and the experimental groups ofⅠ,Ⅱ,Ⅲ,ⅣandⅤwere fed with the basal diet supplemented with 10%,20%,30%,40%and 50%probiotic fermentation feed prepared with Kinggrass No.1,respectively.The feeding experiment was composed of a 7 days pre-test period and a 60 days formal test period.The average daily gain,average daily feed intake,diarrhea rate,dressing percentage and feeding gross profit of different groups were calculated and compared.The results showed that,except for experimental groupⅢ(P>0.05),statistically significant(P<0.05)differences in average daily gain between the other 4 experimental groups and the control group were found;the highest average daily gain was observed in experimental groupⅡ(865.24 g per pig),followed by experimental groupⅠ(839.33 g per pig),increased by 23.24%and 19.55%respectively compared with control group;the lowest average daily gain was observed in experimental groupⅤ(552.51 g per pig),which was decreased by 21.31%compared with control group.The highest and lowest average daily feed intakes were observed in experimental groupⅤ(3.35 kg per pig)and control group(2.30 kg per pig),and there were statistically significant(P<0.05)differences in average daily feed intake between the 5 experimental groups and control group.In terms of dressing percentage,statistically significant(P<0.05)inter-group differences were observed among experimental groupsⅢ,ⅣandⅤ,while no statistically significant(P>0.05)difference between experimental groupⅠand experimental groupⅡwas found;with the increase of supplementation rate of probiotic fermentation feed prepared with Kinggrass No.1,the dressing percentage of the black pigs exhibited a deceasing trend;the control group and experimental groupⅤhad the highest and lowest dressing percentage,respectively.The highest feeding gross profit was obtained in experimental groupⅡ(21259.0 Yuan),and the lowest feeding gross profit was obtained in experimental groupⅤ(10325.7 Yuan).In summary,20%dietary supplementation of probiotic fermentation feed prepared with Kinggrass No.1 has the best performance in improving production performance of fattening black pig and obtains the best feeding economic benefit. |
