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它季节偏长。寒冷季节采用沼气地热养猪技术,可提高猪舍地面温度,达到既节能,充分利用粪便发酵产生的沼气,维持猪舍清洁卫生无异味,防控养殖环境污染;又保暖,沼气燃烧加热循环水,提高猪舍育肥温度,降低养殖成本,保持生猪生长适应温度,防病且改善动物福利;还是防潮湿保干燥的好办法。此技术适应了当前养猪产业化发展的新要求,大大提高了养猪效益,推广使用前景十分看好。
In the cold season pigs have high feed consumption, high impact of cold stress, high morbidity and mortality, and fattening and slaughtering time longer than other seasons. The use of biogas geothermal pig breeding technology in cold season, can increase the ground temperature of pigs, to achieve both energy saving, make full use of biogas produced by fecal fermentation, to maintain the pig clean and odor-free, pollution control farming environment; and warm, biogas combustion heating circulating water , Improve pig fattening temperature, reduce farming costs, keep pigs growing to adapt to temperature, prevent diseases and improve animal welfare; or moisture-proof and good way to keep dry. This technology meets the new requirements of the current industrialization of pigs, greatly improving the efficiency of pigs, promote the use of very promising prospects.
