Abstract: A physiological experiment was conducted with five yearling rams, Stara Zagora x Pleven Blackhead crosses, to establish the effect of adding of feed material from grain distillery industry (Zarnela) in the ration on some blood parameters. Zarnela - spirit producing dried residue from wheat (DDGS - Dried Distillers Grains with Solubles) is a feed additive, a byproduct from the production of ethanol from feed material - wheat. The trial consisted of two periods: control and experimental. During the control period, animals were fed a ration of 1 kg barley and 1 kg meadow hay, and during the experimental period – 0.2 kg Zarnela were added in the ration. Blood samples were collected from v. jugularis externa before feeding and 2.5 hours after feeding during both periods after allowing 10-day adaptation to the respective diet. The studied parameters were: urea, total protein, albumin and globulins. The intake of Zarnela resulted in statistically increasing of the urea levels more significant before feeding (P<0.001). The albumin/globulin ratio was 0.310 in experimental period and in control - from 0.291 to 0,294. Although the levels of albumins were in the ranges 15.0-15.2 g/l, twice lower than minimum of normal, the levels of total blood protein and globulins are in the norm. There were neither considerable changes in total protein and globulins.
