Feeding and Management of Pigs in Winter

Nursing pigs is the most important stage in the production of pig farms. Since piglets who have just weaned in the delivery room take 28 days as the standard and weigh 8-9 kg, it usually takes 2-3 days for pigs of this weight to adapt to the new environment. Piglets who just entered the nursery should not only have adequate temperature, but also have clean drinking water, good palatability and nutritious digestible feed.

The temperature range of pigs who have just entered the nursery is controlled at about 24 ℃, which can not be lower than 22 ℃. Pigs entering the nursery had better choose to transfer in the afternoon or in the evening, which can reduce the stress reaction of pigs and, secondly, reduce pig fighting. It is best that pigs in the same litter in the delivery room are transferred to the nursery and continue to be raised in the same field. pigs with more heads can be merged into other pens, and it is best to choose to group at night. however, we must abide by the principle of "dismantling more without dismantling less, staying strong without leaving weakness, night and daytime disharmony". For individual severely malnourished pigs with injuries and diseases, it can bring a lot of convenience for feeding and management, and reduce the infection rate and mortality rate. Many pig farms either sell or get out of bed to fattening houses when their weight reaches 20 kg, but in the northwest, the winter temperature is generally between minus 18 ℃ and minus 36 ℃, so it is recommended that 23-25 kg of pigs should get out of bed. Many large-scale pig farms use ground heating when the temperature is low in winter, and the humidity of the pig house with ground heating is high. In order to reduce or reduce the humidity, the enclosure should minimize the use of water to flush the circle. At noon, you can open the window or exhaust fan for ventilation. The pigs who have just entered the nursery are trained at three points to eat, drink, defecate and sleep. In order to increase the feed intake of pigs, the illumination time can be prolonged. The night before entering the nursery, the pigs are illuminated with light for 4-6 hours. The pigs that are under-weight, seriously infected and worthless are eliminated before entering the nursery.
