Many breeding sows, especially primiparous sows, are prone to lactation disorders during the postpartum lactation period, such as insufficient or no lactation. Among them:There are two types: pathological and non-pathological, pathological mainly mastitis and so on. Here we focus on the prevention and treatment of non-pathological agalactia and oligomastomy. Analyzing the actual situation, we believe that endocrine disorders, improper feeding management and stunted growth and development are the main reasons for the occurrence of sows without milk and lack of milk, and the specific reasons are as follows.
1.During gestation, especially in the late stages of pregnancy, the sow is malnourished, emaciated, and the mammary glands do not develop well.
2.The mammary glands of primiparous sows are not well developed, and the hormones and nervous system functions that promote lactation are disordered.
3.The number of litters or the age of the sow is on the older side, the digestive function is reduced, the appetite is not vigorous, and there are problems with digestion and absorption.
4.Sows are fed too much energy feed during pregnancy, and must not be raised as fattening pigs, otherwise the pig will be overweight, resulting in the development of the reproductive system and endocrine disorders.
5.Sows develop reproductive system infections such as obstetric tractitis, endometritis and other diseases after farrowing. In order to ensure the normal growth of piglets, various effective measures and methods should be taken in time to prevent the reduction of sow lactation.
1. Strengthen nutritional management in the later stages of pregnancy
Appropriately increase the amount of protein feed, feed more soybean milk, bran and animal feed after farrowing for lactation, or the afterbirth (dried storage) left by the sow when farrowing is soaked in water and cooked, and fed to the sow. For obese and dairy-free sows, reduce the energy feed and at the same time increase exercise. If possible, you should feed more green and juicy feed, because of its phenol oxidase content, as long as it is fed properly, it can increase lactation.
Generally speaking, sows have no milk or insufficient milk volume, and the overall performance is poor appetite, sluggish eating, and even anorexia, so this phenomenon must be eliminated with stomach medicine or feeding some appetite-stimulating feed. In addition, vitamin B complex or feed containing such substances has a beneficial effect on lactation, it can enhance digestion and absorption, enhance metabolism, and stimulate the appetite of pigs.
2. Scientific preventive health care and first-class measures
There are many methods of lactation, which can be selected according to specific local conditions, but the root cause of low milk quantity should be found out first and corresponding measures should be taken, such as high-yielding sows are too slow to feed after giving birth, insufficient feeding or sick people are prone to lack of milk. It can enhance digestion and absorption, enhance metabolism, and stimulate the appetite of pigs. In practice, there are very farmers who use Xu Mutong Daddy Wang to promote milk feed The effect is very good, and the specific plan is as follows:
Preventive care (long-term):Sows are used 30 days before farrowing - weaning period, once a day, add 30-50g of daddy king mixed feed additives to feed, which can prevent the occurrence of poor milk quality, less milk, no milk and other conditions.
**Measures (postpartum):After the sow gives birth to piglets, follow up the milk situation of the mother animal, once a day, add 100g of daddy king mixed feed additives to feed it, and use it for 7-10 days.
During the hot and cold seasons, the number of farmers who report insufficient lactation after giving birth increases. For sows with no milk or less milk, scientific prenatal and postnatal health care can be used to reduce the occurrence of no milk or less milk in sows, thereby reducing piglet diarrhea and improving their survival rate.
