Sow raising and breeding method

Abstract

The invention relates to a sow raising and breeding method. Through the method, a disperse, random and traditional raising method is converted into concentrated, continuous and balanced assembly line production according to ecological and physiological characteristics of sows, an all-in and all-out process is implemented, and annual balanced production is performed according to the breeding rhythm. The key technology of all-in and all-out production according to the breeding rhythm is estrus synchronization. Estrus synchronization of the sows can be achieved through three methods, namely (1) estrus synchronization of the multiparous sows is achieved through a simultaneous weaning method; (2) estrus synchronization of the sows experiencing the puberty or pregnant sows is achieved through a pen breeding and hormone injection method; (3) estrus synchronization of gilts which are not in the puberty is achieved through a group raising and hormone injection method. The sow raising and breeding method is experience obtained through many years of sow raising, enables the sows to bred regularly, facilitates production and operation management, and enables work to be conducted in an orderly and planned mode.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, in particular to a breeding method for breeding pigs. Background technique [0002] With the improvement of people's living standards, people's requirements for quality of life are getting higher and higher, especially in terms of diet. Now large-scale pig raising has become a trend, and pig farms of various sizes have emerged as the times require, so the demand for piglets is increasing, which puts forward new requirements for the breeding pig industry. However, the breeding pig industry is currently facing two problems: [0003] 1. Driven by the market economy, there are more and more large-scale pig farms in my country, and the scale is getting bigger and bigger, and the demand for piglets is also increasing. However, there is currently no scientific standard for breeding pigs. Every pig breeding enterprise is Breeding based on own experience; [0004] 2. Different breeding pigs hav...
