A kind of hybrid production method of high-quality meat pig

Abstract

The invention relates to a hybridization production method for high-quality pork pigs, and belongs to the field of animal genetic breeding. The high-quality lean meat type cross-bred pigs containing 75% of the blood relationship of local pigs are generated by forming Suzhou and Huaibei cross-bred pigs with Suzhou pigs as male parents and Huaibei pigs as female parents and conducting athwart cross fixing. By means of the hybridization mode, the good blood relationship of Chinese local pigs is fully used, good meat quality and reproductive capacity are kept, the number of the produced hybrid pigs born in each litter is 13 or more, the weight is increased by more than 590 g every day, the carcase lean meat percentage is larger than 51%, and marbling is 4 scores to 5 scores. Compared with the Huaibei pigs, the weight of the pigs four months to six months old is increased by 52.45% every day on average, and the carcase lean meat percentage is increased by 22.10%; meanwhile, the score of the marbling is increased by nearly 1 score (5 scores in total) compared with the score of the Suzhou pigs, the meat quality is obviously improved, and the method provides powerful technical support for high-quality pork pig production.

Description

[0001] 1. Technical field [0002] The invention relates to a hybrid production method of high-quality meat pigs, belonging to the field of animal genetics and breeding. [0003] 2. Background technology [0004] In recent years, good progress has been made in the improvement of pig breeds and the cultivation of new varieties of commercial lean meat in my country, and some high-efficiency hybrid combinations have been produced, which has greatly promoted the development of the pig industry; Deviations in consumption concepts, pig producers blindly pursue daily gain and feed-to-meat ratio driven by interests, resulting in the decreasing content of local pig blood in commercial hybrid pigs in the market, and the quality of pork is obviously declining; at the same time, foreign pigs The introduction of a large number of pigs has seriously impacted the original high-quality local breeding pig resources in my country, resulting in a single breed of pigs, shrinking local resources, and...

Suzhong pig is a new breed of high-quality, high-yielding, lean-meat pigs bred by Taihu pigs and Dan-line Landrace pigs as parents. The pigs have high fecundity, obvious estrus, strong adaptability and disease resistance, strong physique, and are easy to raise , but the meat quality still needs to be improved, and Suzhong pigs are white-coated pigs, which are not suitable for the high-end market's consumption demand for black high-quality meat pigs
