High-efficiency and quality-preserving methods for local fine-bred pigs

Abstract

The invention discloses a high-efficiency and quality-preserving method for local fine-bred pigs. In order to overcome the problems of excessive hybridization of local fine-bred pigs, serious loss of genetic characteristics, quality decline, large investment in quality and quality preservation, high cost, and poor effect and benefit, the present invention establishes a central population in the central population area of ​​the core production area of ​​local fine-bred pigs. The outer fringe populations are established outside the central population area, and then constitute the basic original ethnic group; each ethnic group is fed according to the similar conditions of more than 50% of the mainstream farmers in its origin; Piglets are used as commercial piglets. The invention is used for high-efficiency preservation of breed and quality of local fine-bred pigs, which can not only effectively protect the purity and excellent quality of local fine-bred pigs, return the quality of pork to the proper level, and reasonably reflect the reasonable hybrid utilization effect and benefits, but also is easy to implement , the cost of keeping species and quality is lower by more than 70%, and the benefit is increased by more than 50%.

Description

technical field [0001] The invention relates to a breeding and feeding method for pigs, in particular to a high-efficiency and quality-preserving method for local fine-bred pigs. Background technique [0002] With the facilitation of transportation, the abuse of hybridization methods, and the excessive pursuit of economic interests, the existing local excellent pig breeds have been seriously degraded and their quality has declined, making pork without the special flavor of pork; and due to the serious decline in the purity of local excellent pig breeds , so that reasonable crossbreed utilization cannot select the male and female parents with qualified purity, the advantage of crossbreed utilization is reduced, and the benefit of raising pigs is seriously affected. [0003] However, according to the existing system, the method of breeding and breeding of fine varieties is not only large in investment and high in cost, but also has poor effects and benefits. It often fails to ...

Problems solved by technology

[0002] With the facilitation of transportation, the abuse of hybridization methods, and the excessive pursuit of economic interests, the existing local excellent pig breeds have been seriously degraded and their quality has declined, making pork without the special flavor of pork; and due to the serious decline in the purity of local excellent pig breeds , so that reasonable crossbreed utilization cannot select male and female parents with qualified purity, the advantage of crossbreed utilization is reduced, and the benefit of pig raising is seriously affected

[0003] However, according to the existing system, the method of breeding and breeding of fine varieties is not only large in investment and high in cost, but also has poor effects and benefits. It often fails to achieve the set goal, and even the population gradually decreases and dies, causing irreparable losses.
