Twelve steers of three different breeds were exposed to five feed and water regimes in order to characterize changes in plasma antidiuretic hormone (ADH) concentrations. No breed differences were found in plasma ADH concentration. Plasma ADH concentration rose (4.2 to 22.0 pg/ml) during dehydration. By 3 hr hydration, plasma ADH concentrations dropped dramatically (over 50%) to 9.2 pg/ml. No changes in plasma ADH concentrations occurred during feed restriction and refeeding. Hematocrit percentages were also determined and differences are hypothesized to relate to probable differences in environmental adaptability and genetic selection for meat or milk production among the three breeds.
选用三种不同品种的十二头公牛，使其接受五种饲料和饮水方案，以确定血浆抗利尿激素（ADH）浓度的变化特征。未发现不同品种之间血浆ADH浓度存在差异。脱水期间，血浆ADH浓度升高（从4.2皮克/毫升升至22.0皮克/毫升）。补水3小时后，血浆ADH浓度急剧下降（超过50%）至9.2皮克/毫升。限饲和重新喂食期间，血浆ADH浓度未发生变化。还测定了血细胞比容百分比，并推测差异可能与这三个品种在环境适应性以及肉用或乳用生产的遗传选择方面的潜在差异有关。
