Method for improving sow pregnancy rate

Abstract

The invention provides a method for improving a sow pregnancy rate. The method comprises the steps of pre-breeding preparing, seminal fluid collecting and storing before breeding is carried out and estrus detection and breeding of a breeding sow. According to the method, the pregnancy rate of a sow can be increased more than 95%, the empty pregnancy rate for sow breeding is greatly lowered, the service life period of the sow is prolonged, the morbidity of a sow breeding system is greatly lowered, and the piglet birth rate is stable.

Description

technical field [0001] The invention belongs to the technical field of breeding. More specifically, it relates to a method of increasing the conception rate of sows. Background technique [0002] The mating of sows, that is, the conception of sows has a decisive impact on the production of live pigs, and how to further increase the conception rate of sows is of great significance. [0003] The goal of the breeding room is to use healthy breeding boars to timely mating with sows that meet the breeding condition to increase the conception rate. The daily management of weaned sows should focus on estrus stimulation. After weaning, the breasts swell due to milk production, and when milk production and reabsorption are in balance, the lactation process gradually ceases. After 2-3 days of weaning, breast swelling decreases, cellulite begins to decompose, and FSH (follicle-stimulating hormone) stimulates oocytes to develop into follicles, and the ovarian follicle ligament will in...

Problems solved by technology

[0004] At present, when sows in pig farms are mating, due to reasons such as poor estrus of weaned sows or unreasonable mating methods, etc., the first mating or re-mating of multiparous sows is unsuccessful, and the proportion of sows that have been empty for a long time If the proportion is large, the feeding cost will increase, and there will be a large economic loss. In addition, due to the inability to breed in time, the farrowing rate of the pig farm will be greatly affected, and it will be difficult to improve the economic benefits, which is not conducive to the development of the pig farm. Therefore, it is urgently needed A method that can greatly mobilize estrus stimulation and timely mating of sows. Successful mating of primiparous and multiparous sows to improve the pregnancy rate of sows
