Sow feed and breeding method thereof

Abstract

The invention relates to the technical field of cultivation, particularly a sow feed and a breeding method thereof. According the gestation physiologic characteristics of sows and nutritional requirements in different stages, an early-gestation-stage feed, a later-gestation-stage feed and a lactation-stage feed are respectively given to the sows in different stages; Chinese herbal medicine components are added into the feeds in various stages to sufficiently promote the sows to take in sufficient nutrient substances, thereby promoting the growth and development of embryos; and the feed can promote and enhance the digestion and absorption systems of the pregnant sows, obviously increases the number born alive, lowers the rate of embryonic death, and enhances the birth weight and uniformity of the baby pigs.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of breeding technology, in particular to a feed for sows and a feeding method thereof. [0003] 【Background technique】 [0004] The healthy and efficient breeding of sows is very important to the pig breeding industry. It is not only conducive to providing high-quality and healthy piglets, accelerating the healthy and rapid growth of live pigs, stabilizing pig prices, and promoting social stability. It can also reduce the risk of sow breeding and improve sow breeding. The cost is conducive to increasing the income of the farmers and improving the enthusiasm of the farmers. There are many factors that affect the healthy and efficient breeding of sows, the most important ones are sow feed and sow breeding mode. [0005] The nutritional requirements of sows vary greatly in different reproductive stages, so it is very important to use appropriate feeds and feed appropriate amounts at different stages for the heal...

AI Technical Summary

Problems solved by technology

Research and practice have shown that high nutrient intake in the early pregnancy is not conducive to the survival of embryos and the feed intake of sows during lactation, so feed restriction should be implemented for sows in the early pregnancy; and nutritional restriction in the second trimester will have a negative impact on sow body condition, Fetal growth and muscle fiber accumulation, mammary gland development, and birth weight have great changes; increasing the feeding level in the late pregnancy has a certain effect on promoting the birth weight and survival rate of piglets, but excessive feed intake will cause a decrease in feed intake during lactation, Increased body weight loss and decreased lactation, resulting in decreased production capacity; the nutritional level of lactating sows not only directly affects the lactation ability of sows and the growth and development of piglets, but also affects the reproductive performance of sows in the next litter

At present, most of the actual production is to buy general-purpose concentrated feed or premixed feed on the market, and then make it into a full-price diet. Feeding sows in this way cannot meet the precise nutritional needs of sows at different reproductive stages.
