Is it good to wean piglets early? Why?

Effectively improving the annual output of sows can make better use of the production performance of sows. The average psy in China is 16- 17, and it is generally two a year. The most direct measure to improve management conditions or increase the number of PSY by about 0.2 is early weaning. There are more than 25 overseas psy with advanced aquaculture technology, and there is still a lot of room to narrow the gap. After effectively reducing the probability of mastitis, the damage to sows can be reduced. In daily feeding, some piglets don't cut their teeth after birth, and when the sow's milk is insufficient, the piglets will not lose milk.

Adjust temperature and humidity to prevent cold and hot reaction. Pay attention to cold and warmth in cold weather and heatstroke prevention and cooling in hot weather. The fence temperature is suitable for 16-22. The feed is good Because the digestive function of piglets is not complete, the feed should be 4: 6 concentrated feed for suckling pigs or 12% concentrated feed with good adaptability and digestibility. Feed quantitatively on time, feed less, and add appropriate microecology, probiotics, glucose, etc. To improve palatability and promote digestion. It turns out that raising pigs in rural areas is YueYang-age weaned piglets. Early weaning is a pig-raising theory put forward by scientific pig-raising and an important link to improve pig-raising effect. Pig farms are generally weaned during 14-28, and some pig farms are weaned at the latest 35 days, but not as early as possible.

We know that sows are normal about 1 14 days pregnant and mate on 7- 10 days after weaning. In order to improve the utilization rate of sows, the only thing that can be considered is to shorten the lactation time of sows. Let's compare two sets of data. The mating days of sows after weaning are 7 days, the weaning days are 25 days and 35 days, and the average number of uncertain mating days during pregnancy is 5 days. Weaning syndrome always occurs when piglets are weaned. Because there is no breastfeeding, they need to eat feed to supplement their nutrition. However, piglets do not adapt to feed, which leads to nutritional diarrhea, and piglets gradually lose weight and even dehydrate. It will take some time for the weight of weaned piglets to recover slowly, indicating that the feed will be fed for nothing during this time, the feeding time will be delayed, and the growth rate of piglets will be greatly affected.

In order to wean piglets early, it is necessary to solve the problem of weaning syndrome and reduce losses. Therefore, piglets should be lured and fed with high-quality suckling pig feed 5 ~ 7 days after birth, so that piglets can adapt to the taste of feed as soon as possible, and then meet the nutritional needs of growth through eating feed. In addition, when the quality of breast milk is not good, it can prevent diarrhea in piglets. When weaning, breast milk is not needed at all, and feed is used to satisfy nutrition, so there will be no weaning syndrome.
