Embodiment 1

[0024] A kind of breeding method of new Yimeng black pig, it is characterized in that

[0025] (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;

[0026](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;

[0027] Wherein the composite bacteria...

Abstract

The invention belongs to the field of animal genetics and breeding and animal feeding and production. Specifically, Yimeng black pigs are used as female parents and Fengjing pigs are used as male parents to produce Fengyi binary hybrid sows, and Dingyuan pig boars are used as terminal parents. Ben, crossed with Fengyi binary sows to produce Xinyimeng black pig commercial pigs, the litter size is 13, the birth weight is 1.4 kg, the weaning weight is 8.9 kg at 28 days, and the body weight at 60 days is 19 kg. During the fattening period, the daily gain is 720 grams, the feed-to-weight ratio is 2.9, the lean meat rate is 61%, and the intramuscular fat rate is 3.8%. The growth, development, reproduction and other performances of Yimeng black pigs have been greatly improved, and the application prospect is broad.

Description

Technical field [0001] The invention involves the selection method of new Yimeng Black Pig, which belongs to the field of animal genetic breeding and animal breeding production. Background technique [0002] Yimeng Black Pig is produced in the junction of the three counties of Yinan, Yishui, and Yixian County in the northern part of Linyi District, Shandong Province. In 1982, Yimeng Black Pig was included in the "Chinese Pig Seed" compiled by the Ministry of Agriculture and officially became a representative of my country. Local varieties.Yimeng Black Pig has the characteristics of "full body black, all -cooked top, covered with ears, and double ridges.High reproductive power, the number of nests of nests is more than 13 or more, the growth rate and the performance of fattening performance are outstanding, June age weighs 67 kg, the average daily weight of fattening is 600-620 grams, the lean meat rate of carcass is 51-52%, meat qualityDetection is excellent, extensive adaptabili...
