摘要
45头杂种母猪于配种后第28天采血,用放射免疫法测血浆中硫酸雌酮含量。以0.5ng/ml为界线作判断妊娠与否的标准。妊娠诊断的准确率是100％。妊娠母猪的血浆硫酸雌酮水平和胎儿数呈正相关(r=0.501,n=43,P<0.01)。
Plasma oestrone sulphate concentration was measured by RIA with samples from 45 sows of crossbreed on the 28 days after mating. More than 0.5ng oestrone sulphate/ml indicated pregnant and less than 0.5ng/ml indicated non-pregnancy of sows, overall accuracy of pregnancy diagnosis was 100 per cent.
