Sow is the place where both sows and piglets are raised, so the sow that was built should not only meet the sow's requirements, but also consider the physiological characteristics of the piglets. The cold resistance of the newborn piglet is poor, the temperature in the circle is too low to be frozen and frozen, and it is frozen to death. When the sow is built, attention should be paid to the insulation. The newborn piglet is of weak physical condition and is often easily crushed by the sow. Attention should be paid when constructing the sow circle. Effective anti-stress measures, poor disease resistance of piglets, muddy ground and high humidity in pigsty, are easy to get diarrhea, pneumonia and other diseases. When constructing sows, attention should be paid to solve the contradiction between environmental sanitation and accumulation in pigs. More than 10 days after birth, it is necessary to train for food. When constructing sows, care must be taken to set a suitable place as a feeding place. According to the requirements of sow and piglet physiology on the construction of pig houses, when constructing sows, it is best to use a single row enclosed pig house with a rear walkway. Each lap raises a sow with piglets and applies extra-fertilizer. (Figure) The area of ​​this sow area is relatively large. Only 10.5 square meters can be reached where the mother is sleeping. It is entirely possible to install a piglet pressure-proof shelf on both sides of the sow's bed against the wall, plus a playground in front and a walkway behind it. Feeding of sows and feeding of piglets can be carried out either in the circle or on the playground. It is not affected by wind and rain and is beneficial to humans and pigs. Secondly, because the pigsty is closed, there is a wall facing the south, a window on the wall, and a pig entrance and exit under the window. Therefore, the heat insulation in the circle is better. In the cold season, the pig can also consider firing, and the piglet will not freeze. Third, the use of extra-fertilizer outside the circle, dry and clean within the circle, is beneficial to disease prevention and health care of piglets. However, the cost is higher and it occupies more land. If the conditions are not permitted, the sows that are currently widely used in the local area can be modified according to the requirements of the above mother and piglets. The requirements for renovation are: heat preservation performance should be improved, deep pit composting, at least to shallow pit compost, to ensure that the sow sleeping place is clean and dry; to improve piglet feed and sow feeding environmental conditions, so that piglets and Sows can eat well and sleep well. In order to meet the requirements of the farmer's saying, “It is no coincidence to raise pigs and food is sufficientâ€. Universal A.I. Sheaths With Green Insert Universal A.I.
