Problems solved by technology

However, due to the introduction of the idea of ​​focusing on introduction and neglecting breeding, the performance of the imported pigs has been seriously degraded, and one generation is not as good as the next generation. Therefore, it is necessary to carry out continuous breeding, and carry out necessary unified measurement and evaluation and joint breeding to improve the performance and quality of breeding pigs in our province.
[0003] Although Wannan black Huai pig has the advantages of early sexual maturity, large number of litters, strong adaptability and tolerance to rough feeding, it has disadvantages such as slow growth, high carcass fat rate, low meat yield, high feed-to-meat ratio, and low economic benefits. , no longer meet the needs of modern pig production

Embodiment Construction

[0024] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments are used for detailed descriptions, as follows:

[0025] A method for hybrid breeding of Jianghuai black pigs, comprising the following steps:

[0026] (1) The high-yielding dam line Huai pig selected from Anhui local breed Huai pig is used as the female parent, and the high-yield male line Berkshire pig selected from the Berkshire pig is used as the male parent for the first crossing. Pigs, forming a hybrid first-generation Bahuai binary sow group;

[0027] (2) Using the Bahuai dual-element pig as the female parent, and the male parent of the black Berkshire pig for the second cross, the offspring will be a new strain of zero-generation pigs, which contain 25% of the Huai pig lineage and 75% of the Berkshire pig Pig lineage;

[0028] (3) Group locked-up breeding and multi-generation breeding stage: 4-5 gene...

Abstract

The invention discloses a hybrid breeding method for Jianghuai black pigs. The method comprises the steps that bred high-yield Huai pigs serving as female parents and bred high-yield Berkshire pigs serving as male parents are hybridized for the first time to produce a first-filial generation sow group Berkshire-Huai binary species, and excellent sows of the produced hybrid offspring are selected and reserved; the excellent Berkshire-Huai binary sows obtained in the first step and the black Berkshire male parent pigs are hybridized for the second time, and the produced offspring is Berkshire-Huai zero-generation pigs of a new strain, wherein the Berkshire-Huai zero-generation pigs have 25% of Huai pig lineage and 75% of Berkshire pig lineage.

Description

technical field [0001] The invention relates to a breeding method for raising pigs, in particular to a hybrid breeding method for Jianghuai black pigs. Background technique [0002] In recent years, our province has spent huge sums of money to introduce a large number of foreign lean breed pigs, which has played a certain role in the genetic improvement of pigs in our province. However, due to the introduction of the idea of ​​focusing on introduction and neglecting breeding, the performance of the imported pigs has deteriorated seriously, and one generation is not as good as the next generation. Therefore, it is necessary to carry out continuous breeding, and carry out necessary unified measurement and evaluation and joint breeding to improve the performance and quality of breeding pigs in our province. . [0003] Although Wannan black Huai pig has the advantages of early sexual maturity, large litter size, strong adaptability and rough feeding tolerance, it has disadvanta...
