Feed for improving productivity of sow and feeding management method of sow

Abstract

The invention provides feed for improving productivity of a sow and a feeding management method of the sow, and relates to the technical field of cultivation. The sow feed comprises an estrous sow feed, a pregnant sow feed and a nursing sow feed. The feeding management method of the sow comprises the steps of feeding management and disease control. According to the feed, a ratio of the three feed is reasonable; the feed is green and safe; a preparation process is simple; differential feeding is specifically performed in stages in a cultivation process; different nutritional requirements of the sow in the different stages are met; the health of the sow is ensured; a conception rate of the estrous sow is high; a piglet survival rate of the pregnant sow is high; the probability of abortion, stillbirth and fetal mummification is reduced; qi and blood of the nursing sow normally circulate; skin and hair are healthy; milk secretion is smooth. According to the feeding management method, the sow is specifically fed, and an attention is paid to the disease control of the sow, so that a cultivation benefit is maximized; purposes of saving the cost and increasing a utilization ratio of the feed are achieved; popularization is worthy.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of breeding technology, in particular to a feed for improving the production performance of sows and a feeding management method for sows. [0003] 【Background technique】 [0004] In recent years, with the improvement of people's living standards, the demand for pork has continued to rise, the overall quality of pork has been continuously improved, and the breeding industry has been required to continue to develop. The concept of animal nutrition consists of comprehensive supplementation and balance of various nutritional elements needed for animal growth and development. Therefore, it is beneficial to the growth and development of pigs, healthy and non-toxic, which can accelerate pig growth and ensure the quality of pork is the goal pursued by people. [0005] Sow feeding is one of the important links in pig production, and the nutritional status of sows seriously affects the reproductive performance of sows ...

AI Technical Summary

Problems solved by technology

In the current breeding situation, there are more and more large-scale pig farms, and the scale is getting bigger and bigger, but there are fewer and fewer free-range farmers. In addition, there are fewer and fewer types of sow feed, and the types of nutrients are becoming more and more monotonous. Sows raised under natural conditions can absorb tens of thousands of nutrients, and the sows can be used for more than ten years; however, the types of nutrients that sows in large-scale breeding factories are exposed to are only dozens of types, resulting in sows The amount of nutrients consumed remains the same, but the types are getting less and less. The result is a serious deviation from the natural nature of sows, which causes great changes in physiological, psychological and body conditions during the reproductive cycle of sows, and the incidence of reproductive disorders and diseases increase, the use life will be severely reduced, and the production performance will be seriously affected, which will eventually increase the feeding cost of large-scale breeding. Therefore, it is urgent to develop a breeding method that is efficient and improves the production performance of sows
