An experiment was conducted with 30 Improved Walachian sheep, aged 2-3 years, fed pelleted feeds in winter and kept on pasture in summer. The study was aimed at studying the amounts of vitamin A, vitamin C, cholesterol, glycaemia, and bilirubin in blood. The described rearing technology, gravidity, and lactation showed no adverse influence on the values of the studied parameters, which were within the physiological numeric range. Vitamin A ranged, on an average, from 1.06 to 1.92 mumol 1(-1), vitamin C from 34.06 to 54.5 mumol 1(-1). Cholesterol ranged from 1.47 to 2.26 mumol 1(-1), and the marginal values of glycaemia were 2.33 and 4.02 mumol 1(-1), and those of bilirubin were 3.17 and 5.81 mumol 1(-1). From the very beginning of the experiment, vitamin A showed low values; this indicates the need for a simultaneous examination of the administered feed for the content of carotene.
