Embodiment

[0018] 1. Selection of gilts: sows with no defects in health, normal genital development, no more than 200 days old (preferably weighing more than 80kg), and sows with measured results (not required by non-breeding farms).

[0019] 2. Improve lighting. Illumination is a very important factor affecting the estrus of gilts. It can be changed by replacing the curtain with good light transmission or increasing the light in the house. The original seed farm uses transparent roller shutters to improve the lighting conditions in the gilt house.

[0020] 3. Feed green material. Insist on feeding 0.5-1kg of green feed (elephant grass) to gilts every day, which can not only improve the palatability but also increase multivitamins, improve the health of sows, and promote the normal estrus of gilts.

[0021] 4. Feed in large pens and exercise properly. The gilts are reared in large pens, according to the standard of 1.5m2 / head-2m2 / head, and the number of each pen is controlled at 8-12....

Abstract

The invention discloses a method for increasing the oestrus breeding rate of replacement gilts. The method includes the steps that first, replacement gilts are selected; second, illumination is improved; third, the replacement gilts are fed with green fodder, wherein each replacement gilt is fed with 0.5 kg to 1 kg of green fodder every day; fourth, large swinery raising is performed, and the replacement gilts are made to move appropriately, wherein the replacement gilts are raised in a large swinery; fifth, oestrus promotion should be performed properly in time; complete archive management should be performed. Due to the measures of improving the illumination, feeding the replacement gilts with green fodder and building detailed replacement gilt archive cards, the replacement gilts can be managed better, and the oestrus breeding rate of the replacement gilts is effectively increased. The oestrus breeding rate of the replacement gilts is gradually increased from 81.55% to 92.17% and from 92.17% to 95.19% and increased by nearly 14%, and direct economic loss caused when the replacement gilts are low in the oestrus breeding rate and are finally eliminated is reduced.

Description

technical field [0001] The invention relates to a method for increasing the mating rate of pigs, in particular to a method for increasing the mating rate of back-up pigs in estrus. Background technique [0002] At present, in intensive pig farms, because of the production according to the plan and process, a large number of gilts must be replenished every year. However, following that, the low mating rate of gilts in estrus is another headache. How to aphrodisiac aphrodisiac gilts to increase their estrus mating rate has also become one of the problems that pig farms must face and solve. Contents of the invention [0003] The purpose of the present invention is to provide a method for improving the estrus mating rate of reserve pigs. [0004] This method of increasing the mating rate of quilt pigs in estrus: [0005] ①Selection of gilts: Healthy and free of defects, normal genital development, age not exceeding 200 days, body weight above 80kg, with test results, but no...
