MILK PRODUCTION OF SHEEP FED WITH SUNFLOWER MEAL AND SOYBEAN GRAIN

摘要

The common agricultural policy of the European Union to stimulate the cultivation of legumes creates more opportunities to use more protein sources from own production. The purpose of this study was to establish the influence of sunflower meal and thermally treated soybean grain on the milk production of sheep of the breed Pleven Blackface.The experiment was performed with two groups of ten sheep which had 2-4 lactations and was carried out two months after they gave birth. The rations were composed of meadow hay and corn grain, and as a protein source in the first group sunflower meal wasused, while the other group was fed with heat-treated soybean grain. During the 42-day trial period, no significant differences in the amount and composition of the milk obtained between the two groups were observed. It was established that the time ofcurdling milk is longer in sheep receiving grain from soybeans. From this study, it can be concluded that heat treated soybean grain can be used as the sole source of protein in dairy sheep with daily milk yield up to one liter.
