Embodiment 1

[0031] 1. Preparation of sows before mating

[0032] (1) Ensure timely and successful mating of weaned sows

[0033] 1. Lactation period: shortening the lactation period will prolong the interval from weaning to breeding.

[0034] 2. Feeding during lactation: Excessive weight loss during lactation will prolong the interval from weaning to breeding. Therefore, it is necessary to consume a large amount of lactation feed with high nutrient concentration in the late lactation period.

[0035] 3. Feed intake from weaning to mating: High feed intake can reduce the interval from weaning to mating, increase ovulation (especially primiparous sows), and increase pregnancy rate.

[0036] 4. Contact with boars: Sows should be kept near boars or in contact with boars every day.

[0037] 5. Mixed groups: increase stress stimulation but may cause some damage.

[0038] 6. Sheds: There must be enough space for sows to be in heat when they are raised in groups.

[0039] 7. Temperature: When...

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...
