摘要
采用放射免疫测定法(RIA),对中国美利奴军垦型细毛羊血清中孕酮(P4)浓度进行了检测,结果表明,繁殖母羊在休情期小于0.1ng/mL,发情排卵当天(0d)为0.236ng/mL,发情后(+1d)孕酮水平显著增高,达到5.25ng/mL,(0d)和(+1d)的孕酮含量差异十分显著(P<0.01).提示该品种羊发情周期中卵巢的机能活动或生殖特性,可能与其它细毛羊存在一定差异.
Detected the progesterone density of Xinjiang Merino millitary type in blood serum through Radioimmuno-AssayRIA the results indicate that beeding ewes' progesterone density were respectively less than 0.1ng/mL0.236ng/mL 5.265ng/mL during dies trus update to EstrusOd and Estrus +1d. Thecontent diversity between 0d and +1d was very significant P<0.01. The results predicted that during the Estrus cycle ovaria function and reproduction character of Xinjiang Merino millitary type were different from other Merino.
