Raising method for improving sow breeding quality

Abstract

The invention discloses a raising method for improving the sow breeding quality. The method comprises the following steps of (1) management before fertilization: 1, feed management and 2, illumination management; (2) management after fertilization: 1, feed management and 2, illumination management. The method provided by the invention has the advantages that through the reasonable control and matching of two important factors of feed and illumination in the sow breeding process, the body physique of a sow is well enhanced; the immunity of the sow is effectively improved; the fertility rate and the embryo survival rate are improved; the parturition and empathema time is shortened; meanwhile, the body weight of newborn piglets can be increased; the occurrence rate of the piglet yellow and white diarrhea is reduced by about 40 percent; the piglet survival rate is improved by about 8 percent; the culture benefits are well improved.

Description

technical field [0001] The invention relates to a feeding method for sows, in particular to a feeding method for improving the reproduction quality of sows. Background technique [0002] Pork is an indispensable source of meat in people's lives. Healthy and efficient breeding of sows is crucial to the pig farming 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, improve the breeding efficiency of sows, help farmers increase their income, and increase their enthusiasm for breeding. There are many factors that affect the healthy and efficient breeding of sows, the most important of which are sow feed and breeding methods. [0003] The nutritional requirements of sows vary greatly at different growth stages, so it is very important to use appropriate feed and feeding methods at different s...

Problems solved by technology

For example, high nutrient intake in the early pregnancy is not conducive to the survival of the embryo and the feed intake of the sow during lactation; the nutrition in the early parturition period should not be too much, otherwise it will easily cause digestive disorders, and a large amount of food will accumulate in the intestinal tract, causing constipation and postpartum reluctance. , fever, and too much milk, the piglets can’t finish eating, which will lead to the occurrence of mastitis and increase the incidence of yellow and white scours in piglets, but they must not have enough physical reserves, otherwise the sows will be born too long, resulting in Lag in production, more weak litters, retained placenta, feigned death, etc. At the same time, the resistance of sows becomes weaker and prone to metritis and mastitis, which manifests as anorexia after delivery, poor milk quality, diarrhea in piglets, and sows after weaning. Problems such as long interval between estrus
