What is a breeding pig? thank you

The so-called improved varieties generally refer to varieties with fast growth, good quality, strong resistance, stable characters, adaptability to natural conditions in a certain region and suitability for large-scale breeding. But the specific farmers should be determined according to their own breeding purposes. If the main purpose is to produce products with excellent meat quality, many local pig breeds in China, such as Lantang pig, Taihu pig and Ningxiang pig, are excellent varieties. Duroc pig, Landrace pig, Large White pig and lean pig mating lines are excellent varieties, if the purpose is to grow fast and have high slaughter rate.
