It is recommended to prevent mastitis after sow weaning. Some breeders start to reduce the supply of concentrate, green feed and water 3 days before weaning, and some only supply water on the day of weaning. These incorrect feeding methods, It often leads to delays in sow estrus. In fact, whether or not to reduce the material before and after weaning has nothing to do with mastitis. Because the pig's breast structure is very special, there is no milk pool, can not store milk, so it will not induce mastitis due to excessive storage of milk. The sow's milk should be accumulated in the breast, because it is the accumulation of milk in the mammary gland that causes the internal pressure of the mammary gland to increase, thus stopping the formation and secretion of more milk, without the need to reduce, break, or break the material. To reduce milk. Weaning is not a common problem in sows. One of the reasons is excessive weight loss during lactation. It is especially common in primiparous sows because their own development is not completed, and the nutritional needs of fetal development and lactation are also guaranteed. Sows with poor body condition often show delayed estrus, so 3 days before weaning, should not be reduced, and should not be cut off on the day of weaning. Conditional breeders should be fed a special material for empty sows rich in vitamin E, vitamin C, carotene, choline and methionine. At the very least, we should continue to feed the lactating sow to the estrus, instead of feeding the pregnant sow.
