Embodiment 1

[0031] The sow of the lion-headed Wannan Huayan pig was used as the female parent, and the Taihu Erhualian boar was used as the male parent to carry out crossbreeding to produce the first-generation Wantai sow; the first-generation Wantai sow was used as the female parent, from Hubei Province The Berkshire boars used by the breeding pig farm in Huanggang City were crossed, and the offspring produced were both improved piglets, which were recorded as pig breed A. The improved piglets were raised, and the feeding cycle was recorded. After the piglets grew up, they were slaughtered, and the skin thickness and lean meat percentage of the raw meat were measured. The results are shown in Table 1.

[0032] The boars, sows and piglets are raised in the following feeding methods:

[0033] 1. Breeding boars and sows should be one head per lap. The area of ​​breeding sow pens is 3 square meters per head, and the breeding boar pens are 10 square meters per head. Breeding boars should be o...

Embodiment 2

[0048] The sow of the lion-headed Wannan Huayan pig was used as the female parent, and the Taihu Erhualian boar was used as the male parent to crossbreed the Wantai sow of the first generation hybrid; The Locke boar was used as the male parent for crossbreeding, and the offspring produced were both improved piglets, which were recorded as pig breed A. The improved piglets were raised, and the feeding cycle was recorded. After the piglets grew up, they were slaughtered, and the skin thickness and lean meat percentage of the raw meat were measured. The results are shown in Table 1. The concrete feeding method of boar, sow and piglet is consistent with embodiment 1.

Embodiment 3

[0050] The purebred lion head shaped Anhui pig is raised, the feeding method is consistent with embodiment 1, the feeding cycle is recorded, and the piglets are slaughtered after they grow up, and the skin thickness and lean meat percentage of the raw meat are measured. The results are shown in table 1 .

[0051] Table 1 is the result of raising and slaughtering pigs in Examples 1 to 3

Abstract

The invention discloses a method for improving southern Anhui spotted pigs. The method comprises the following steps: with a southern Anhui spotted sow as a female parent and a Tai lake erhualian boar as a male parent, carrying out hybridization to breed cross uni-generation southern Anhui-Tai lake sow; and with the cross uni-generation southern Anhui-Tai lake sow as a female parent and a Berkshire boar / Duroc boar as a male parent, carrying out hybridization to generate the improved piglet. The piglet obtained by the technical scheme has short raising cycle, the slaughtered raw meat skin is thin and the lean parentage is high.

Description

technical field [0001] The invention relates to the field of pig breeding, in particular to a method for improving Huanan Hua pig. Background technique [0002] Wannan flower pig is one of the local fine breed pigs in my country. It is a precious local genetic resource variety with a long history. It has the advantages of resistance to rough materials, strong adaptability, gentle temperament, good motherhood, high reproductive rate, early maturity, and delicious meat. The disadvantages are thick skin, slow growth rate, and more fat. Contents of the invention [0003] The main purpose of the present invention is to provide an improvement method for Wannan Hua pig, which can maintain the original advantages of Wan Nan Hua pig, improve the lean meat ratio and skin thickness of pork and shorten the breeding cycle of pigs. [0004] In order to achieve the above object, the present invention adopts the following technical solutions to implement: [0005] A method for improving...
