In the production, the sow’s lactation power can be identified based on the sow’s appetite, sensation, breasts, backfat, and its number of times and lactation times. Specifically, the sows’ appetite during breast-feeding is relatively strong, and they can eat a lot of green and juicy feed or full-rate diets, and the daily intake is more than 6 kg. Higher power. Some sows do not have significant weight gain during pregnancy, and they do not lose their weight during lactation. Such sows do not usually have high lactation. Sows with high milking power had 28 to 32 milkings per day and night, and each time the milking time was more than 20 seconds. Sows with low milking power had less milking times and the milking time was short. If the sow's breasts are plump, the intervals are obvious, and the nipples are shiny and elastic, the piglets rarely “sucking teatsâ€. Such sows generally have high milk yields. If there are piglets in the front and back nipples, the common piglets have teats in their mouths, or the piglets can occasionally look around for teats, indicating that the sow's lactation levels have begun to decrease. If the whole litter of piglets "pigs up the tits", it means that the sow has very little lactation. In terms of appearance, sows with thick shoulders, thick hips, and obese hips all have a low level of lactation, while sows with a single back ridge usually have a higher amount of milk.
