Thyroid function was studied by estimating of plasma-protein-bound iodine (PBI), in buffaloes, from 0 to 57 days postpartum. PBI values (microgram/100 ml) were lowest on day 1 postpartum, followed by a gradual increase by day 57. The values were consistently lower (P less than 0.01) during summer (3.79 +/- 0.13 micrograms/100 ml), as compared to winter (5.06 +/- 0.27). A lower value (P less than 0.01) was obtained in animals requiring less than 30 days (3.53 +/- 0.45) or more than 30 days (4.88 +/- 0.27) for uterine involution. The values were 4.56 +/- 0.13, 5.03 +/- 0.68 and 2.72 +/- 0.50 in animals requiring less than 25, 25-50 and more than 50 days for initiation of follicular development (P less than 0.01). Similarly the values were 4.95 +/- 0.38, 3.95 +/- 0.45 and 4.03 +/- 0.59 in buffaloes having postpartum oestrus intervals less than 45, 45-90, and more than 90 days (P less than 0.01). Higher values (P less than 0.05) were obtained in conceiving (4.55 +/- 0.41), as compared to non-conceiving animals (4.21 +/- 0.31). It can be concluded that the thyroid function is depressed during summer and in poorly reproducing buffaloes.
通过测定产后0至57天水牛血浆蛋白结合碘(PBI)来研究甲状腺功能。产后第1天PBI值(微克/100毫升)最低,随后逐渐上升至第57天。与冬季(5.06±0.27)相比,夏季PBI值持续较低(P<0.01)(3.79±0.13微克/100毫升)。子宫复旧所需时间少于30天(3.53±0.45)或多于30天(4.88±0.27)的动物,其PBI值较低(P<0.01)。卵泡发育开始所需时间少于25天、25至50天、多于50天的动物,其PBI值分别为4.56±0.13、5.03±0.68和2.72±0.50(P<0.01)。同样,产后发情间隔少于45天、45至90天、多于90天的水牛,其PBI值分别为4.95±0.38、3.95±0.45和4.03±0.59(P<0.01)。与未受孕动物(4.21±0.31)相比,受孕动物(4.55±0.41)的PBI值较高(P<0.05)。可以得出结论,夏季和繁殖能力差的水牛甲状腺功能会受到抑制。
