The research set out to examine how adding coconut oil to the diet of yearling rams affected a number ofclinically significant biochemical variables in their blood. The experiment used nine male Blackhead Plevenyearling rams, with an average starting weight of 45.2 kg. A two-period experimental design was used. Thefirst group of yearling rams were given 1 kilogram of barley and 1 kg of grass hay (ration I) during the firstperiod. The second group got 0.800 kg of barley, 0.200 kg of sunflower meal, and 1 kg of grass hay (rationII). The third group also received 0.800 kg of barley, 0.200 kg of sunflower expeller, and 1 kg of grass hay(rating III). As part of the morning feeding routine throughout the trial, all groups received 0.02 kg ofcoconut oil via cannulas. Including coconut oil in ration II led to higher blood total and HDL cholesterol 2.5hours after consumption (p<0.001). Despite the increased rumen lipid content, serum triglyceride levels inanimals given Rations I and II were unaffected. Coconut oil significantly reduced blood ASAT activity inall three diets, both before and after feeding (p<0.05 and p<0.001, respectively). Animals given ration II hada reduction in serum alkaline phosphatase both before (p<0.001) and after feeding (p<0.05) after the additionof coconut oil.
