- Abstract
The aim of this study was to determine the influence of performance test traits of young gilts on the number of piglets born and reared during their reproductive life. The material for the study consisted of the entire population of Puławska sows, kept in breeding herds and included in a genetic resources conservation programme, in the years 2001-2019. A dataset was created for 2722 Puławska gilts with complete information from live fattening and slaughter evaluation and reproductive performance results. Fattening and slaughter traits were evaluated using the Piglog 105 ultrasonic device. To determine the influence of selected factors on sow production performance, four groups of factors were established (for parity, body weight, daily gain, and meatiness). Young gilts evaluated at a body weight of up to 95.9 kg and with daily gains of up to 519 g/day were found to have statistically significantly the poorest production parameters in the first and subsequent parities. Excessive meatiness in the carcass of sows (=60%, class S) caused a reduction in the number of piglets born and reared, mainly in the first parity. In the second and third parity, a high meatiness value reduced the number of piglets reared.
