Within one week after weaning, the phenomenon of negative weight gain occurs from time to time, which has different degrees of impact on the growth status and survival rate of piglets during the nursery period and the growth and development of future generations. So, how do we prevent and cope with negative weaning weight gain?
First, pay attention to the feeding management of pregnant sows, and improve the newborn weight of piglets and the lactation rate of sows
According to the development law of embryos and mammary glands, we raise them in stages to increase the primary weight of piglets and the lactation rate of sows, so as to obtain better primary weight of piglets.
Starting from 90 days of pregnancy, the diet prepared with the addition of yvisu in the sow feed can increase the primary weight of the piglet and help the full development of the mammary glands; after childbirth, on the basis of adequate feeding, it can further improve the quality of nursing sow milk, promote uterine rejuvenation, reduce the risk of postpartum infection, improve the weight of the piglet weaning nest, and the sow full-price material is used with yvisu, the effect is better!

Second, the piglet early heat preservation, iron supplementation, feeding
Piglet early heat preservation, iron supplementation, feeding, can enhance the piglet physique, exercise the gastrointestinal function of piglets, reduce the occurrence of intestinal diseases. When weaning, the piglets are large, the gastrointestinal function is perfect, the digestive function is good, the amount of food intake is large, and the whole body consumption is less after weaning.
Generally, after the piglet is born, it is trained to sleep in the incubator and release milk regularly, so that the postpartum sow can not only get full rest, but also be stimulated by the concentrated arch milk massage of the piglet; and the piglet eats milk at the same time, and the uniformity is good. Iron supplementation at 1 to 3 days old, 7 days old began to add you milk treasure, around 18 days old began to eat normally, and after 1 week basically can be weaned.
Third, do a good job of environmental control and reduce stress
Weaning and new environmental stress can easily cause pigs to eat and sleep abnormally, and even the disease, which can cause physical consumption. When the piglet is close to the weaning period, the number of breastfeeding times of the sow can be artificially reduced, so that it can turn its attention to the feed and avoid the severe stress caused by sudden weaning. At the same time, do a good job in the environmental control of the nursery, and use the nursery as a micro-ecological environment treatment to maintain a warm, dry, clean and upward environment, so that the piglets feel comfortable, thereby reducing the stress of the new environment.
Fourth, strengthen nutrition to prevent the occurrence of disease
A few days before the piglets are weaned, they begin to prepare diets with Youniubao, and add euvidin to prepare diets after feeding to 30 catties to further supplement the nutrition required by piglets, thereby reducing the consumption of piglets' physical strength, and at the same time reducing stress to prevent diarrhea in piglets.
