Abstract
Description
Technical field
[0001] The invention relates to a pig raising system, in particular to a pig raising system based on a microbial fermentation bed and adopting negative pressure ventilation for temperature adjustment. Background technique
[0002] At present, the shortcomings of simple large-scale intensive pig raising have become more and more prominent, and many ecological pig raising methods have emerged, the most important of which is the pig pens with microbial fermentation beds. Fermentation bed pig raising is simply: the use of microbial bedding (sawdust, wood chips, bran powder, chaff, cottonseed hull powder, cotton stalk meal, coconut hull meal, peanut hull meal and other substances with high crude fiber content. One or several mixtures, plus compound microbial strains) to raise pigs. Pigs live on microbial fermentation litter that is 60-90 cm thick (thick in the south and thick in the north), and eat and drink on the litter. , The microbial fermentation in the cushion m...
