Embodiment Construction

[0040] Suhuai pig breeding method comprises the following steps:

[0041] The Xinhuai pig was used as the female parent, and the lean-meat Yorkie pig was used as the male parent for crossbreeding. Each generation was selected for five times, and the selected pigs were selected as the next generation of breeding pigs.

[0042] In this example, 50 Xinhuai sows were cross-breeded with Yorkie boars to obtain 50 litters of piglets.

[0043] First selection: After the mating sows give birth, the number of first-born pigs is 9 or more, the number of reared pigs at 40 days is not less than 8, and the number of litters above three litters is 13 or more, 40 or more. The number of piglets raised in days should not be less than 11, the number of effective teats of piglets should be 7 pairs or more, and the rest should be discarded. There are 45 litters with 513 piglets (the minimum number of litters among 45 litters is 9 piglets) , the maximum litter size is 15);

[0044] The second sel...

Abstract

The invention discloses a Suhuai pig breeding method, comprising the following steps of: carrying out hybridizing cultivation with new Huai pig as a female parent and pork type yorkshire pig as a male parent, carrying out five times of selection and remaining of each generation, and using the selected and remained pigs as parent pigs for next generation; and repeating first to fifth times of selection and remaining, carrying out level identification on the reproductive performance of sows when the second generation is bred, and applying the sows to production when the primiparous young pigs are more than 9 and the multiparous young pigs are more than 13. The bred Suhuai pig is strong in constitution, is strong in disease and stress resistance, and has good applicability to environments of cultivation places.

Description

technical field [0001] The invention relates to a breeding method for animal varieties, in particular to a breeding method for pig varieties. Background technique [0002] New Huai pig is a new pig breed bred by crossing Huai pig and Yorkshire pig in Jiangsu Province. It is mainly distributed in the lower reaches of Jiangsu Province. It has the characteristics of strong adaptability, large litter, tolerance to rough feeding, and good hybridization effect. The whole body of Xinhuai pig has black hair, with only a small amount of white spots at the end of the body. The head is slightly long, the mouth is straight and slightly concave, and the ears are medium and large, hanging forward and downward. The back and waist are straight, the abdomen is slightly larger but not sagging, the hips are slightly inclined, the limbs are strong, and there are more than 7 pairs of nipples. Adult boars weigh 230-250 kg, and adult sows weigh 180-190 kg. However, the growth rate of Xinhuai ...
