Abstract. Title of the paper: Influence of growth and side fat thickness on reproduction and rearing performance of gilts. I. Comparison of characteristics growth, side fat thickness and reproduction performances
Studies were executed in two breeding farms with gilts of Leicoma (farm B) and German Landrace (farm M). The influence of growth and side fat thickness on reproduction and breeding Performance was analysed. Date of birth, body weight and side fat thickness measured to selection (180.
