Hollow bricks for pig beds: pigs avoid rheumatism and grow fatter and stronger

At present, pig production in China is mainly small-scale or free-range, @#@227@#@ conditions are relatively poor. In northern China, temperatures from December to February of the following year are very low, only a few pig houses have heating, and the vast majority have low indoor temperatures, with pigs lying directly on concrete floors that are both damp and cold, causing a high incidence of rheumatism in pigs (such as lameness and paralysis), which affects weight gain speed and feed conversion rate. In particular, paralysis in farrowing sows leads to culling, causing great losses.

In recent years, the author has used the method of laying hollow bricks as pig beds to prevent rheumatism in pigs, with excellent results. By September, it is recommended that farmers make good use of the valuable 2~3 months before winter to renovate pens and ensure that pigs safely overwinter.

Method of operation: ① The pig beds in growing, fattening, and sow farrowing houses are laid with hollow bricks, the gaps between bricks are filled with cement, and no cement is applied on top; pigs lie on the hollow bricks, which are both dry and warm. ② Improve the sow farrowing bed. The advantage of the existing farrowing bed is that it saves space, piglets do not come into contact with manure, and intestinal diseases are fewer; the disadvantage is that sows on the farrowing bed are vulnerable to drafts from the ground, especially after farrowing when the sow is weak and highly prone to illness. The space from the ground to the farrowing bed should be built up with bricks, with hollow bricks on the upper layer, level with the mesh surfaces on both sides where the piglets move.
