To study the effect of compound mineral licking bricks on the growth performance and biochemical indexes of fattening sheep,grouped feeding method was used in this experiment,and those sheep were selected according to similar weight and body size,healthy condition and fine growth and development,which were divided into control group,shed fattening group and grazing fattening group. Control group was given basic diet,with basic diet plus mineral licking bricks for shed fattening group and grazing fattening group. The results showed that supplementary mineral licking bricks improved daily gain of fattening sheep obviously,and significantly increased daily gain of shed fattening group( P 0. 05).Supplementary mineral licking bricks could effectively improve diet protein utilization in fattening sheep,and could enhance body immunity. The results indicated that supplementary mineral licking bricks has a good effect on the improvement of growth performance and immunity of fattening sheep.
