Abstract
Abstract The aim of the study was to discuss breeding of pigs of the Puławska breed, which is included in a Genetic Resources Conservation Programme, and to analyse performance parameters that are useful in domestic pig production. The Puławska breed is the oldest native breed of pig in Poland. Since 1996 it has been protected by a genetic resources conservation programme, owing to breeding traditions and the production traits characteristic of the breed. The use value of these pigs is currently at the level of maternal breeds: number of live piglets born per litter – 10.54; number of piglets reared per litter – 9.37; daily weight gains – 569 g for breeding boars and 562 g for breeding gilts; meat content – 54.6% for breeding boars and 54.9% for breeding gilts. An important element in favour of the use of this breed in domestic production of fresh pork and pork products is its meat quality parameters. The mean values for physical traits (WHC 22.42%, pH45 6.47, pH24 5.63) and chemical parameters (protein 22.70%, fat 2.65%) are characteristic of meat of normal quality. The Puławska breed can be used to produce high-quality fresh meat and meat products, including traditional and regional ones. Puławska pigs are bred and reared according to the principles of sustainable agriculture, which reduces the negative impact of pig production on the natural environment.
