微生物发酵玉米秸秆饲料在生长育肥猪养殖中的应用

目的]研究发酵玉米秸秆饲料对生长育肥猪生产性能的影响.方法]选用120头健康体重约24.47 kg的杜长大三元杂生长育肥猪,随机分成4个处理,每个处理3个重复,每个重复10头猪;处理l即对照组（CK）饲喂基础日粮饲料,处理2、3、4在基础日粮中分别添加10％、20％和30％发酵玉米秸秆饲料,试验正式期60d.结果]与处理1（CK）相比,10％、20％、30％处理组育肥猪的平均日增重、平均日采食量均无显著差异（P＞0.05）;30％处理组料重比比处理1（CK）提高了6.84％ （P ＜0.05）;20％处理组腹泻率比处理1降低了6.87％ （P ＜0.05）,30％处理组比处理1降低了11.66％ （P ＜0.01）;20％、30％处理组死亡率分别比处理1降低了29.80％和37.63％ （P ＜0.05）;从经济效益分析来看,与处理1（CK）相比,20％、30％处理组毛利润分别提高15.1％和10.36％ （P ＜0.05）,每头猪分别多获利20.31和13.94元.结论]在生长育肥猪日粮中添加微生物发酵玉米秸秆饲料能够满足育肥猪的生长需要,当添加量为20％～ 30％时能够降低生长育肥猪的腹泻以及死亡率,降低养殖成本,提高经济效益,且以添加20％的量效果最佳.

Application of Microbial Fermentation Corn Stalk Feed in Growing-Finishing Pigs Breeding

Objective] This study was conducted to observe the effects of microbial fermentation corn stalk feed on growth performance of growing-finishing pigs.Method] One hundred and twenty weighting 24.47 kg growing-finishing pigs （Duroc × Landrace × Large White） were randomly divided into four treatment groups with three replivates（ten pins per pen）.Treatment group Ⅰ （the control group） was supplemented with 0 microbial fermentation corn stalk feed in basal diets,treatment groups Ⅱ,Ⅲ and Ⅳ were basal diets supplemented with 10％,20％ and 30％ microbial fermentation corn stalk feed,respectively.The feeding experiment was conducted for 60 days.Result] The results showed that compared to control group（CK）,daily average weight and daily feed intake in the treatment groups was not significant difference （P ＞ 0.05） ; feed conversion ratio increased by 6.84％ in the treatment group Ⅳ （P ＜ 0.05） ; diarrhea rate decreased by 6.87％ and 11.66％ in the treatment group Ⅲ （P ＜ 0.05） and Ⅳ （P ＜ 0.01）,respectively ; death rate decreased by 29.80％ and 37.63 ％ in the treatment group Ⅲ and Ⅳ （P ＜ 0.05）,respectively; profit analysis showed that compared to control group （CK）,gross profit increased by 15.1％ and 10.36％ in the treatment group Ⅲ and Ⅳ （P ＜ 0.05）,and maked a profit of 20.31 yuan and 13.94 yuan per pig.Conclusion] In summary,the findings suggested that adding fermentation corn stalk feed to part of growing-finishing pigs diets can meet the growth needs of fattening pigs,and can decrease diarrhea rate and death rate,reduce breed cost and improve the economic benefit while adding by 20％-30％,and the best of adding amount was 20％.
