Eating colostrum colostrum is the milk secreted by sows three days before delivery, which contains a lot of immunoglobulin, which can improve the immune ability of newborn piglets. Therefore, piglets should eat enough colostrum within 24 hours after birth.

Feeding piglets grows fast, and the weight at 7 days of birth is twice that at birth. After three weeks of lactation, the lactation yield and nutrition of sows will gradually decrease, but the growing piglets need more and more nutrition.

Therefore, artificial feeding should be used to supplement the shortage of pig milk, generally starting in 5-7 days, and attention should be paid to the rich nutrition of feed, the quality of protein and the supply of adequate drinking water.

Arch soil characteristics:

Pigs are born with the genetic characteristics of arching soil, and arching soil for food is a remarkable feature of pig feeding behavior. The pig's nose is a highly developed organ, and the sense of smell plays a decisive role in digging the soil to find food.

Although in modern pig houses, pigs still show the characteristics of arch foraging, and try to occupy a favorable position in the trough every time they eat;

Sometimes, two forelimbs step on the trough to eat. If the trough is easy to approach, some pigs even get into the trough and stand in the corner of the trough, just like wild boar arching for food, arching along the trough with their noses and mouths.
