How to increase milk yield in sows

As the scale and frequency of production in the farm is getting higher and higher, many sows have a litter all their lives, and there are nearly ten sows in a litter. It is good for sows a few days ago, and the milk production of sows with a lot of time will not keep up. Milk production will decline and affect production. This is also a headache for many farmers. Then Shuai Shuai will tell you how sows can improve milk production.

1. The regularity of milk production in sows

The milk production of sows is generally postpartum sows. Only after parturition, sows' breasts secrete milk, but generally, the milk yield of sows decreases greatly after about 20 days. Colostrum is the milk secreted by sows within three days. At this time, the milk protein content is the highest, the immunoglobulin content is very high, more than three days later the milk belongs to regular milk. The protein content in normal milk is only 27% of that in colostrum, and there is a rule that the part near the sow's nipple produces more milk than the part behind the nipple, and the sow produces more milk during the day than at night.

Diet management of sows

The milk yield of sows also has a lot to do with their usual diet, so we should pay attention to feed. Those who have raised pigs must have heard the saying, "this feed is good, you can smell fish, and sows love to eat it." so what does that mean? In fact, we generally supplement the crude protein in the feed with fish meal, which has a relatively high protein content, and the kinds of amino acids in the protein are very complete, and the proportion of amino acids is more balanced. In addition to these, we also need to supplement some feed with high moisture, rich vitamins and good palatability, so that pigs can have more appetite and enhance the peristalsis of intestines and stomach. Promote the gastrointestinal digestion function of sows, so that the absorption of nutrients is better, milk production can be higher, feed must be from less to more, slowly let pigs adapt, it is forbidden to feed mildew and rotten green feed.

III. Classified lactation of sows

Think of some pigs with a slightly better physique, stronger pigs should be fed relatively less before giving birth, especially when adding prolactation feed rich in high-quality protein and vitamins, some thin pigs can be fed more, and the postpartum food intake of sows can slowly catch up. For some obese sows, their breast lactation organs may be infiltrated by fat, so this will have a great impact on their milk secretion, reducing the amount of milk production of sows, so to promote lactation for sows, you can use hormones to promote lactation and subcutaneously inject prolactin once a day for three consecutive days. Some thinner sows produce less milk, as long as it is caused by malnutrition, malnutrition can check whether there are parasites in the belly, and if not, consider improving the feed.

The above is the way for sows to increase milk yield. Have you learned it? I hope this article will help you.
