Abstract
Total thyroxine (TT) and free thyroxine index (FTI) were measured in peripheral plasma of cows. The samples were collected at the time of insemination from 66 cows showing pronounced signs of the heat and from 56 cows showing weak or silent heat. Neither TT or FTI in plasma differed significantly between the two categories of oestrous cows.
摘要
在奶牛的外周血浆中测量了总甲状腺素（TT）和游离甲状腺素指数（FTI）。在输精时从66头表现出明显发情迹象的奶牛以及56头表现出发情微弱或安静发情的奶牛身上采集了样本。两类发情奶牛血浆中的TT和FTI均无显著差异。
