The effect of heat stress and dehydration on certain blood parameters were studied in the pigeon. Pigeons exposed to heat-stress and dehydration showed higher haematocrit values. Serum cyclic AMP levels, both with and without corrections made for difference in haematocrit, showed a more than two-fold increase in heat-stressed and dehydrated pigeons. Serum triglyceride level (before and after correction for haematocrit difference) in the experimental birds dropped to less than half that in the control birds. Total serum thyroxine (T4) did not show significant change in the experimentals (either with or without correction for haematocrit), although bound T4 and T3 index showed a statistically significant drop in the experimental group, after the correction for haematocrit. Total serum protein and albumin values after correction for haematocrit difference showed significant decreases in experimental birds. In pigeons exposed to heat-stress and dehydration, serum sodium increased while potassium dropped (with and without haematocrit correction). Heat stress and dehydration did not have any significant effect on serum levels of total cholesterol, uric acid, sodium, potassium, calcium and magnesium.
研究了热应激和脱水对鸽子某些血液参数的影响。暴露于热应激和脱水环境下的鸽子血细胞比容值更高。无论是否对血细胞比容差异进行校正，热应激和脱水鸽子的血清环磷酸腺苷水平都增加了两倍多。实验鸟类的血清甘油三酯水平（校正血细胞比容差异前后）降至对照组鸟类的一半以下。实验动物的总血清甲状腺素（T4）没有显著变化（无论是否校正血细胞比容），尽管校正血细胞比容后，结合T4和T3指数在实验组有统计学意义的下降。校正血细胞比容差异后的总血清蛋白和白蛋白值在实验鸟类中显著降低。在暴露于热应激和脱水的鸽子中，血清钠增加而钾下降（无论是否校正血细胞比容）。热应激和脱水对血清总胆固醇、尿酸、钠、钾、钙和镁水平没有显著影响。
