Abstract: The objective of this investigation was to establish the milk yield, the physicochemical and the fatty acid composition of milk from sheep of the Synthetic Population Bulgarian Dairy Breed, reared indoor and on natural pasture with supplementation of the concentrate mixture. The milk yield during the suckling period and the milk yield of the fourth dairy control significant surpass those of the first, second, third and fifth dairy controls (P<0.01; P<0.001). The average values for the physicochemical composition of the milk correspond to the requirements for content in sheep milk. For the first time has been studied the fatty acid composition of sheep milk from the Synthetic population Bulgarian dairy breed, reared indoor and during the pasture period. A higher content of saturated fatty acids during the indoor period and a low content of mono- and polyunsaturated fatty acids compared to milk, obtained during the pasture feeding has been established.
