Abstract

Until recently, selection of dairy sheep breeds was focused almost exclusively on increasing the amount of milk produced and so today they produce several times more milk than breeds selected for meat and wool. However, due to the permanent striving for increasing sheep milk production udder weight becomes too great, and suspensory system can not withstand this overweight so it ruptures more often. That significantly shortens the duration of animal’s production life and adversely affects udder suitability for machine milking. Therefore, there is an increasing interest in adding a so-called functional udder traits in sheep breeding programs recently, such as udder morphology, with the aim of increasing the biological and economic efficiency of milk production, not by increasing production, but reducing its costs. The economic importance of sheep udder morphology has lately been more pronounced also in Croatia because in more and more herds machine milking starts to apply. Therefore, the aim of this study was to show the most important factors that affect the variability of sheep udder morphology.
