Production traits of pigs of intrabreed type “Pripyatsky” in Landrace breed at breeding enterprises

Abstract

To meet the population’s demand for meat pork, breeding programs aimed at breeding and selection of pigs with high reproductive, fattening and meat traits were carried out for several decades. Over the years, a number of new types, lines and breeds of pigs were created and tested in the world. It should be noted that the gene pool of foreign super-meat breeds (Pietrain; Duroc; Danish, French, German, Canadian Landrace and Yorkshire) was used to some extent in the development of new domestic meat genotypes of pigs. A rational use of the genetic potential of farm animals allows accelerating the selection to improve their reproductive, fattening and meat traits. The Republic of Belarus arranged its own production of high-value animals represented by intrabreed type-pigs in the Landrace breed with the following productivity indicators: prolificacy – 12.5 animal units, milk yield – 65.5 kg, number of piglets at weaning – 11.6 animal units, litter weight at weaning at the age of 30 days – 91.6 kg, meat content in carcass – 65–67 %, well adapted to the technological conditions of breeding and industrial complexes, providing the overall need of pig breeding in obtaining high-quality pork; saving foreign currency for import; the possibility of exporting finished products to CIS countries.
