The birth of sows has a very important impact on the development and lactation of the mammary glands, which is also the basis for sows to provide nutrition to piglets. It is now clear that mammary gland development and lactation are the result of the combined effects of pituitary prolactin, growth hormone, estrogen, progesterone, etc. In addition, the secretion of milk is also affected by the intensity and frequency of sucking stimulation on the nipples and the amount of milk discharged. If young sows are not given sufficient and strong sucking stimulation after giving birth, they should be observed frequently with B-ultrasound. If the breast function degenerates quickly, it will lead to low breast lactation function after multiple births. In actual production, many breeders will foster young sows immediately after seeing that they do not have much milk after giving birth, and rush them to the breeding house after weaning. This practice is very inappropriate, but it is common, so that the elimination rate of young sows is high. It is best to use B-ultrasound for pigs to observe the breast condition of sows frequently.

The development of mammary glands gradually accelerates in the second trimester of pregnancy, and you cannot feed too much. Feed too much. Ultrasound observation of pigs shows that there is too much fat deposited in mammary cells. No matter how you induce lactation after sows give birth, it will be useless. The milk is less and the milk quality is poor. Similarly, sows cannot be too fat. A large amount of fat invades the mammary gland, which will also inhibit the development of mammary cells. Ultrasound observation of pigs shows that sows are too thin. During pregnancy, especially in the late stage, the nutrients in the feed are insufficient, especially energy and protein, which causes sows to be too thin and have no milk.

Ultrasound for pigs

Don't feed too much after giving birth. Gradually increase the daily feeding amount after 3-5 days. Provide sufficient drinking water, add salt, multivitamins (such as Jiasubu), plant polysaccharides (such as Vitality Yuan), etc. appropriately, and drink drum skin water when necessary. Early supplementary feeding after giving birth, good quality and large quantity of feed will lead to excessive secretion of mammary glands. In addition, the piglets are small and the amount of sucking milk is limited. Milk stagnation causes mastitis. These phenomena are very obvious when observed by B-ultrasound for pigs.

It is necessary to maintain good sanitary conditions in the pig house. After the sow gives birth, the body resistance is relatively weak. It is necessary to prevent bacteria from entering the breast through the loose nipple hole and inducing mastitis. Therefore, it is necessary to use Pig B-ultrasound to examine the breast.
