Analysis of reasons for culling of sows in production herd

Popis výsledku v původním jazyce

The objective of this work was to analyse reasons for culling of sows from a basic herd of a selected production farm. From the total number of 540 sows (maternal line Topigs 40) in basic herd, 119 sows were culled during the observation period. Cullingwas evaluated in aspects of parity order and causes. Evaluation according to the parity order showed that the highest levels of culling were reached after the 1st and the 2nd parity, with 22 % or 21 % of sows culled from the basic herd, respectively. Inthe aspect of specific causes of culling, the most frequent ones were reproductive disorders (34 %), followed by musculoskeletal disorders (27 %) and low performance (18 %). Other causes (bad condition of mammary gland, health condition) each representedless than 10 % of the cases. The most frequent reproductive disorders were sterility (47 %), anestrus (38 %), difficult farrowings (10 %) and other problems - conception issues, abortions (5%).
