Embodiment 1

[0025] A kind of breeding method of new Yimeng black pig, it is characterized in that

[0026] (1) Using Yimeng black pigs as the female parent and Fengjing pig as the male parent, crossbreed to produce Fengyi dual hybrid sows, and then use Dingyuan pig boars as the terminal male parent to crossbreed with Fengyi dual hybrid sows to produce Xinyimeng black pig commercial pig;

[0027](2) Fermentation of feed: Fermentation of main food materials: 35 parts of soybean meal, 30 parts of wheat bran, 30 parts of soybean flour, 20 parts of bran, 30 parts of hogwash, 3 parts of salt, and 1 part of compound bacterial solution (the above ratio is by weight). Mix and stir the above ingredients evenly, and adjust the humidity of the mixed material to 55-60%, pile it into a pile with a height of no more than 1 meter, width and length, and cover it with a plastic film for anaerobic fermentation for 3-6 days , to obtain fermented feed for hybrid pigs;

[0028] Wherein the composite bacteria...

Abstract

The invention belongs to the fields of animal genetic breeding and animal feeding production. A Yimeng black pig breeding method particularly includes that a Yimeng black pig is utilized as a female parent, a Fengjing pig is utilized as a male parent, the two pigs are hybridized to obtain a Fengyi binary hybridized female pig, then a Dingyuan male pig is utilized as a terminal male parent, the Fengyi binary hybridized female pig and the Dingyuan male pig are hybridized to obtain novel Yinmeng black commercial pigs, the number of the born pigs is 13, the weight of a single commercial pig at birth is 1.4kg, the weaning weight of the single commercial pig is 8.9kg when the commercial pig is 28 days old, and the weight is 19kg when the commercial pig is 60 days old. The daily gain of the weight is 720g in a fattening period, the ratio of the feed to the weight is 2.9, the meat factor is 61%, and the intramuscular fat rate is 3.8%. By means of the method, the performances of growing, developing, multiplying and the like of Yimeng black pigs are greatly improved, and the application prospects are wide.

Description

technical field [0001] The invention relates to a breeding method for Xinyimeng black pigs, and belongs to the fields of animal genetics and breeding and animal feeding and production. Background technique [0002] Yimeng black pigs are produced in the border area of ​​Yinan, Yishui, and Juxian counties in the north of Linyi, Shandong Province.
