The safe overwintering of piglets should pay attention to the improvement of feed quality

The feed formula for piglets overwintering should be adjusted. In the cold season, it is necessary to improve the dietary energy standards, such as adding fat and protein to piglets and lactating sows, increasing the amount of vitamin additives and adding preventive drugs, such as vitamins and salinomycin, to prevent piglet dysentery and improve piglet weight gain. Fourth, in the cold winter season, the daily feeding amount and daily feeding times of all kinds of pigs should be increased. Lactation sows and piglets before and after weaning were fed with high protein diet, and the feeding times were increased once or twice a day to enhance cold resistance, sow lactation ability and piglet growth rate.
