Abstract

The invention discloses a hybrid black pig breeding method taking both output and quality of pork into consideration. The method comprises the following breeding steps: step one, taking Taihu pigs as sows and Berkshire pigs as boars, and obtaining hybrid pigs through hybridization, the hybrid pigs being Taihu-Berkshire pigs; taking Tiegu pigs as sows and Berkshire pigs as boars, and obtaining hybrid pigs through hybridization, the hybrid pigs being Tiegu-Berkshire pigs; step two, taking the Taihu-Berkshire pigs as sows and the Tiegu-Berkshire pigs as boars, and obtaining hybrid pigs through hybridization, the hybrid pigs being Taihu-Tiegu-Berkshire pigs I; taking the Tiegu-Berkshire pigs as sows and the Taihu-Berkshire pigs as boars, and obtaining hybrid pigs through hybridization, the hybrid pigs being Taihu-Tiegu-Berkshire pigs II; and step three, conducting four times of back cross breeding without blood relations on the Taihu-Tiegu-Berkshire pigs I and the Taihu-Tiegu-Berkshire pigs II, and obtaining finished black pigs. Pigs for pork obtained through the method have the advantages of high fertility, fast growing, high pork quality, crude feed tolerance and good adversity resistance.

Description

technical field [0001] The invention relates to the technical field of pig breed selection, in particular to a hybrid black pig breeding method compatible with pork yield and quality. Background technique [0002] Today, the strategic side of international pig production has transitioned from pure lean meat type to lean meat quality type or best quality type. Local breeding pigs in my country have entered the R&D and production stage of high-quality or top-quality meat due to their natural meat quality advantages, but there are serious defects in growth speed and lean meat percentage, so they need to be improved in terms of growth speed and lean meat percentage to achieve the balance between quality and output. balance. [0003] Taihu pig is known as the "king of litter in the world". It has good meat quality and high fecundity. The disadvantage is that the lean meat rate is only 38%-42%, and the fat is arranged in small particles. The cut surface is not smooth and the appea...
