寒冷季节生猪养殖饲料消耗高,冷应激影响大,疾病发病率和死亡率偏高,且育肥出栏时间较其他季节偏长。寒冷季节采用沼气地热养猪技术优点颇多,既节能环保,又能起到防病且改善动物福利的作用。该技术适应当前养猪产业化发展的新要求,能大大提高养猪效益,推广使用前景十分看好。一、沼气地热养猪技术模式沼气地热养猪技术是一项崭新的能源利用模式,通过就地收集猪场猪粪便污物等,沼气发酵 Pigs in the cold season breeding feed consumption, cold stress, disease morbidity and mortality high, and fattening slaughter longer than the other seasons. In the cold season, there are many advantages of using biogas to heat pigs, which not only saves energy and protects the environment but also helps prevent diseases and improve animal welfare. The technology to meet the new requirements of the current industrialization of pigs, pigs can greatly improve the efficiency of the promotion of the use of very promising. First, the biogas geothermal pig technology model Biogas geothermal pig technology is a new energy utilization model, pigs and pig farms through the local collection of dirt and so on, biogas fermentation
