With the continuous development and progress of pig industry, the use of pig equipment has been unanimously praised, saving the time and energy of farmers, and pig equipment also has a certain position. Pig raising equipment includes six series, including fattening pig pen, nursery bed, high culture nursery bed, nodular cast iron bottom, high culture childbirth bed and high culture childbirth bed. There are many small categories of pig raising equipment, as well as careful specifications and models. How to choose the advanced and economic pig raising equipment which is suitable for the scale and technology of pig farm is an important measure to improve the production level and economic benefit.
It is a very important link in pig production to breed sows and newborn piglets. The newborn piglets are small and weak, their function of regulating body temperature is not perfect, and their resistance to cold is poor. In winter, they often suffer from the risk of freezing, crushing and trampling injury. The survival rate of piglets largely depends on the structure of pigsty, heating ventilation and delivery fence.
The parturition column is a kind of monomer column, which is a place for sows to give birth and lactate. In the middle of the delivery fence is the limit frame for sows, which is the place where sows give birth and piglets feed. On both sides are the places where piglets eat, drink, warm and move. Generally, the sow limit frame is made of round steel pipe and aluminum alloy. The rear part is equipped with a leaky floor to remove feces and dirt. On both sides are piglet mobile bars, which are used to isolate piglets. Delivery pens and conservation pens are the key to the design of modern pig farms. It is very important for the survival rate and growth of piglets, lactation and physical recovery of sows to improve the safe and comfortable environment of delivery and care.
