Abstract

The invention discloses a method for breeding pig breeds of Meiling black pigs. The method comprises the following steps that (1) excellent piglets are selected as reserved backup pigs on the 20th day after the birth of the piglets; (2) the secondary optimization screening is carried out after fourth month of the reserved backup pig selection, and high-quality stock pig breeds are selected; (3) when the body weight of the selected high-quality stock pig breeds is increased to 50kg, the selection remaining and the elimination are carried out by utilizing the integral selection indexes and referring to the genealogical ancestry and the somatotype appearance according to the individual and compatriot performance test results, and backup pig groups are selected and formed; (4) male pigs and female pigs in the backup pig groups can mate according to requirements, and pigs with poor growth and development conditions, genetic diseases and breeding difficulty are weeded out. The method for breeding pig breeds of Meiling black pigs is set out according to the actual characteristics of the pig breeds of the Meiling black pigs. When the method for breeding pig breeds of Meiling black pigs is adopted, the purebred pig breeds of Meiling black pigs with good properties and stable hereditary feature can be selected, and the social benefits and the economic benefits are obvious.
