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.

Pulawska 猪的育种和性能潜力——综述

摘要 本研究的目的是讨论遗传资源保护计划中包含的 Puławska 品种猪的育种，并分析对家猪生产有用的性能参数。Puławska 品种是波兰最古老的本地猪品种。自 1996 年以来，由于育种传统和该品种特有的生产特性，它受到遗传资源保护计划的保护。这些猪的使用价值目前处于母猪品种水平：每窝出生的活仔猪数 - 10.54；每窝饲养的仔猪数量 – 9.37；日增重 – 种公猪 569 克和后备母猪 562 克；肉含量——种公猪为 54.6%，后备母猪为 54.9%。有利于在国内生产新鲜猪肉和猪肉产品中使用该品种的一个重要因素是其肉质参数。物理性状的平均值（WHC 22.42%，pH45 6.47，pH24 5.63）和化学参数（蛋白质 22.70%，脂肪 2.65%）是正常质量肉的特征。Puławska 品种可用于生产高品质的新鲜肉类和肉类产品，包括传统和区域肉类。Puławska 猪是根据可持续农业的原则饲养和饲养的，这减少了养猪生产对自然环境的负面影响。Puławska 品种可用于生产高品质的新鲜肉类和肉类产品，包括传统和区域肉类。Puławska 猪是根据可持续农业的原则饲养和饲养的，这减少了养猪生产对自然环境的负面影响。Puławska 品种可用于生产高品质的新鲜肉类和肉类产品，包括传统和区域肉类。Puławska 猪是根据可持续农业的原则饲养和饲养的，这减少了养猪生产对自然环境的负面影响。
