Reasons and countermeasures of sows' refusal to feed

Some sows are disturbed after giving birth and refuse sowing the piglet, often resulting in the death of the piglets. There are several reasons why sows refuse breastfeeding.

1. The sow does not have lactation experience. The first-time sows do not have lactation habits. After the childbirth process, due to nervousness or fear of piglets licking or can not withstand the piglets entanglements, feeding may occur. If such a sow is encountered, the breeder should guard the sow and give careful training. When the sow is lying down, she scratches its belly and watches the piglets fight for the teat to keep it quiet. After the piglet has eaten a few milk, the sow is accustomed to it. In addition, it is best to gild the primiparous sows at the end of pregnancy and massage them regularly so that the sows do not become restless when they come into contact with the nipples, so that they can breastfeed smoothly after birth.

2. Changes in the sow's environment When the sow is transferred to a new place during delivery, she does not adapt to the new environment and she is nervous and does not allow the piglets to feed. Should be rushed to the new pig house a few days before the expected date of birth, so that it has a process of adaptation.

3, sows without milk If the sow is free of milk, the piglets are dragging the sow back and forth, so that the sows are restless. Occasionally, piglets are used to bite the piglets, or simply lie prone, pressing the nipples under the body and preventing the piglets from arching the teats. This situation occurs mostly in malnutrition, dry breasts, thin sows, although there is part of the colostrum after delivery, but will soon become no milk. The solution is to strengthen the sow's nutrition and feed the sows with soy milk, small fish, shrimp, and large intestine soup. When necessary, use traditional Chinese medicine: Codonopsis pilosula, Radix Astragali, Rehmannia glutinosa, Radix quinquefolius, each with 50g, Tongcao 30g, Pangolin 40g, and Shuijianbi. Can also be used kelp 500g, chopped after bloating, add animal oil 50-100g, soup to feed sows. Once the sow has enough milk, it will naturally feed the piglets.

4, postpartum infection due to postpartum infectious diseases in sows, body temperature caused by reduced milk, then the piglets will have aversion to breast milk. Can be treated with antibiotics or sulfa drugs in time. When the body temperature is high, it is necessary to perform fever reduction and fluid infusion to recover the sows as soon as possible.

5, sows suffering from mastitis or piglets bite the sow in this situation sows do not let the performance of breastfeeding is different from the above. The sow’s milk is full, her breasts are swelled, and she calls out at regular intervals to call her pigs. But the pig had just picked up the nipple, and the sow immediately screamed and stood up, even biting the pig. There are two possible reasons for this: First, the sow has an injury to her nipples or mastitis; the piglet causes pain when she eats milk; second, the pigs compete for udders or individual piglets. The fangs are irregular, long, and sharp. , biting the sow's teat, causing the sow to refuse breastfeeding. In this case, it is necessary to check carefully and find that the sow's tits are injured or suffer from mastitis and should be promptly treated. Otherwise, check the pig's teeth and cut the sharp canine teeth with scissors.
