2.3 consisting of 156 older ewes had seropositive rate of 4.5%,this result showed seropositive rate increasing with age compared to the seropositive rate of 0(in flock No.2 of 2 year olds and flock No.1,4 of 3 year olds) to 0.4%(in flock No.5 of 3 year olds).
由156只老母羊组成的第3群的血清学阳性率为4．5％，与2岁的第2群、4岁的第1，4群的血清学阳性率0和3岁的第5群的0．4％相比，结果证明血清学阳性率随年龄增长而增加。
3.Found that antistatic property of flock fabric was increased when the flock was treated by oxygen plasma.
