A physiological experiment was conducted to evaluate the effect of the technological product Optigen® supplemented to the feed of yearling rams at a dose of 12 g. The blood concentrations of glucose, creatinine, urea, total protein, albumin, globulins, and protein coefficient (albumin/globulin ratio) were assayed in samples collected from v. jugularis.A positive influence of Optigen was established, with maintaining higher blood glucose, creatinine and urea levels 2.5 h after feeding (p≤0.05). The increased total protein concentrations during the experimental period suggested for enhanced and stable rates of absorption from the digestive tract into the blood – effect of Optigen’s active principle. Higher albumin/globulin ratio (p<0.001) was demonstrated, as a result of increased albumin levels especially at post feeding hours (p<0.001) and the reduced blood serum globulins (p<0.05). The supplementation of Optigen to the ration did not show any side or adverse effect on the health and welfare of experimental animals.
