The effect of feeding Tribulus terrestris plant powder on performance, digestibility, protozoa morphology, blood and rumen parameters in Iranian Arabic lambs were studied. Eighteen 3 months old Iranian Arabic male lambs with average weight of 16 (±2) kg were assigned to a completely randomized design with 3 treatments and 6 replicates for 60 days. Experimental treatments were control ration and rations with 15 and 30 g Tribulus terrestris plant powder per kg dry matter. The treatments with Tribulus terrestris had the higher protein intake compared to control (P<0.05). The natural detergent fiber digestibility, amount of rumen ammonia nitrogen, the Diplodinium, Ophryoscolex and the total protozoa population in rations containing Tribulus terrestris was lower than control treatment (P<0.05). As ammonia nitrogen amount was 12.98, 9.87 and 9.68 mg/dL for control, 15 and 30 g/kg dry matter (DM), respectively. But the Entodinium and Eudiplodinium population were not different (P>0.05). The content of cholesterol, triglyceride, low density lipoprotein, urea and glucose of blood and liver enzymes of lambs treated with experimental rations were lower than control group; and the high density lipoprotein was higher (P<0.05). The content of low density lipoprotein was 12, 9 and 8 mg/dL for control, 15 and 30 g/kg DM, respectively. According to this current study, effect of feeding Tribulus terrestris plant powder to fattening lambs had significant effect on digestibility, rumen fermentation and blood parameters of Iranian Arabic fattening lambs.
