The aim of the study was to characterize Scottish Highland cattle. Scotch Highland cattle are the oldest existing breed of cattle, which was developed in extremely difficult environmental condition where only the strongest animals could survive. Highland cattle are characterized by many valuable traits, such as resistance to harsh conditions and diseases, efficient feed utilization, as well as good fertility. Thanks to those features Scotch Highland cattle are developed all over the world; nevertheless the total word population is small, counting 28 000 units. Despite the fact that the quality of its meat is unquestionable, in Europe Highland cattle are mainly used in agro tourism farms and for landscape management. Presently, when breed diversity is an issue, Highland cattle should find a place in the Polish agriculture landscape.
The purpose of the study was to evaluate the performance of Scottish Highland cattle in Polish production systems. Research material consisted of the cattle’s performance records provided by the Polish Association of Beef Cattle Breeders and Producers. The data comprised the following traits: cow weight, height at withers and at sacrum, chest circumference, calf weight at calving and at 210th day, calving difficulties, calves stillborn and growth gains. In this study 495 calvings were examined. All calvings were described as “easy, natural, without the need for human assistance.” Similarly good results were observed with regard to calves stillborn: only 4 calves were lost. The studies revealed that the average weight of Highland calves at birth in 2007-2011 remained at a similar level (24 kg for heifers and 25 for bulls), but a decrease in growth gains of calves at the age of 210 days was noted (by over 200 g/day). This phenomenon may have been related to a decreased milk productivity of cows and to genetic factors.
