2.That percentage of abdominal fatyield in groups of the 400 FTU/kg and 600 FTU/kg were higher(P=0.216),and percentage of breast muscle yield in groups of adding 500 FTU/kg and 750 FTU/kg were higher than other two groups.
3.Milk fatyield was higher tnat that of control group when 20g COMBO was fed,while the somatic cell count (SCC) in the milk was markedly lower that those of control and 13g fed groups.
9.Average daily weight gain(ADWG)and feed intake(ADFI),feed conversion rate(FCR),percentage of carcass yield(CYR)breast muscle(BMR) and abdominal fat(AFR),plasma concentrations of uric acid(UA) were determined at the end of the experiment.
10.The clean yield, fat percentage and vegetadle matter rate of the wool of Gansu highland merino were determined by normal methods. The results obtained were as follows:The clean yields of ram, ewe, yearling ram and yearling ewe are 47.00, 57.77,59.36 and 55.18% respectively;
