复方中药发酵料在猪生产中的应用及健康养殖模式的探讨

Application of compound Chinese medicine fermented feed in pigs production and discussion on healthy breeding mode

试验探究复方中药发酵料在猪生产中的运用效果及有效的生猪健康养殖模式。试验选择体质健康、体重为50~55 kg的母猪260头,随机分为2组。对照组母猪饲喂基础日粮,试验组母猪饲喂基础日粮+1%复方中药发酵料。试验期25 d,期间每3 d使用干粉环境改良剂,持续4次。将使用复方中药发酵料和环境改良剂的猪粪进行收集,并添加辅料和海大研究院自研的菌种,进行堆肥发酵处理。结果显示,母猪舍使用综合养殖方案(复方中药发酵料+干粉型环境改良剂),氨气降解速率大幅提升、空气沉降菌降低率提高;母猪采食量稳定提升、猪群腹泻率下降;粪肥有机发酵后所有检测指标均满足且优于国家标准。研究表明,复方中药发酵料可以有效调理猪群肠道健康,提高饲料消化利用率,降低粪臭味;环境改良剂具有干燥养殖环境、降解臭味、抑制有害菌的作用。

The experiment explores the application effect of compound Chinese medicine fermentation feed in pig production and the effective pig healthy breeding mode.In the experiment,260 sows with healthy physical fitness and weighing 50~55 kg were selected and randomly divided into two groups.The sows in the control group were fed the basic diet,and the sows in the test group were fed the basic diet+1%compound Chinese medicine fermentation feed.The test period was 25 days,during which dry powder environmental modifier was used every 3 days for 4 times.Collect pig manure using compound Chinese medicine fermentation materials and environmental modifiers,and add auxiliary materials and strains developed by the Haida Research Institute for composting fermentation.The results showed that after using the comprehensive breeding program(compound traditional Chinese medicine fermented feed+dry powder type environmental modifier)in sow houses,the ammonia degradation rate was greatly increased,and the reduction rate of air sedimentation bacteria was increased.The sow intake was steadily increased,and the pig diarrhea rate was decrease,the proportion of high-quality sows fur was increased.All the test indicators after the organic fermentation of manure meet and exceed the national standards.Studies have shown that the compound traditional Chinese medicine fermented feed can effectively regulate the intestinal health of pigs,improve the digestibility and utilization of feed,and reduce the odor of feces;the environmental modifier has the effect of drying the breeding environment,degrading odor and inhibiting harmful bacteria.
