Feed for sows and breeding method of sows

Abstract

The invention provides feed for sows and a breeding method of sows, and relates to the technical field of breeding. The feed for the sows is prepared from feed for pre-pregnant sows, feed for pregnant sows and feed for lactating sows. The invention also provides the breeding method of the sows. The breeding method comprises the steps of (1) pig house management, (2) feeding management and (3) stocking management. The feed for the sows is reasonable in proportion of the three groups of feed, green and safe, and simple in preparation process; in a breeding process, by means of differential feeding in a targeted way in different stages, the different nutritional requirements of the sows at the different stages can be met, the health of the sows is guaranteed, the farrowing survival rate of the pregnant sows is improved, the probability of abortion, stillbirth and mummy fetuses is reduced, and the lactating sows are smooth in circulation of qi and blood, healthy in fur and smooth in milk secretion. After the feed for the sows and the breeding method of the sows are adopted, the sows are fed in a targeted way, so that the breeding benefit is maximized, the aims of saving cost and improving feed utilization rate are achieved, and the feed and the breeding method are worth of being generalized.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of breeding, in particular to a feed for sows and a breeding method for sows. [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 hea...

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
