Abstract

The invention discloses a breeding method for a four-generation lean pig. The method comprises the following steps: using a high-yield Yorkshire sow bred from a Yorkshire sow as a maternal line femaleparent, using a high-yield Landrace pig bred from a Landrace pig as a maternal line male parent, and using a grown second-generation pig hybridized by the high-yield Yorkshire sow and the high-yieldLandrace pig as a progenitor sow; breeding a Duroc pig with a rapid growing speed from the Duroc pig, hybridizing with a Berkshire pig, and selecting a filial generation and fixing crossing, breedingby generations to form a hybrid pig with a pure color gene, namely a Duba pig is a progenitor boar; enabling the progenitor sow to be hybridized with the progenitor boar, to obtain a parent-generationsow.

Description

technical field [0001] The invention relates to the field of animal reproduction and breeding, in particular to a four-element lean pig breeding method. Background technique [0002] Landrace pigs, Yorkshire pigs, and Duroc pigs are famous lean-meat pigs in the world, and they are also the main breeding breeds currently promoted in my country. In production, landrace pigs are often used as the male parent to cross with the large Yorkie pig female parent, and the offspring "Long × Big" dual hybrid sow is selected as the female parent, and the Duroc boar is used as the terminal male parent for crossing, and the "Duroc" is obtained. × long × large” three-way hybrid offspring are used as commercial meat pigs, usually called “outer three-way”. In many cases, the Landrace and Yorkie are interchangeable, so that the Landrace is the female parent and the Large Yorkie is the female parent. "Wai Sanyuan" has the advantages of good growth performance, high feed conversion efficiency,...
