New breeding and genetic methods in pig breeding in Belarus

Six pig breeds: Belarusian large white, Belarusian meat, Belarusian black and white, landrace, Yorkshire and Duroc are involved in breeding and hydridization of pig breeding in Belarus. More than 85 % of pigs supplied to meat processing plants of the Republic are provided by different combinations of interbreed hydridization.For the effective development of this branch in the Republic, the Scientific-Practical Center on Animal Husbandry of the National Academy of Sciences of Belarus organized the system of selection and breeding work in pig breeding directed to create new competitive breeds, types, and hydrides of pigs adapted to the industrial production conditions and not inferior to the productivity of the analogs of the world selection.The main link of this system is the first-order breeding plants (nucleus units) as new-type plants dealing with the selection and breeding of the best animals with the outstanding genetically conditioned breeding and productive qualities. The second link of this system is the first-order breeding breeders that are completed with high-valuable breeding pigs from the leading nucleus unit and are engaged in their reproduction to obtain grandparents (GP).Assessing the level of the technological development of pig breeding in Belarus during the period to the 2030 year, we predicted the indices for the all predictable years (2020–2030). The existing level of the technological development of the pig breeding branch is assessed as the mean one. During 2020–2021 the pig breeding level will be moderate-high, during 2022– 2023 – high, and since 2025–2030 – intensive.
