Abstract

Background: The study of hormone and blood parameters in male Pati duck was carried out to investigate the changes that occur in these parameters during the post-natal development as better understanding of physiology is necessary for improving the productivity. Methods: The blood and serum sample were collected from Pati duck at 1 month, 6-8 weeks, 20 weeks, 30 weeks and 40 weeks age groups. For each age group 6 representative samples were collected from the jugular vein. Hormones (testosterone, cortisol, triiodothyronine and thyroxine) were estimated using Radioimmunoassay (RIA) and haematological parameters were studied using digital analyser. Result: Age related change observed with Testosterone hormone with maximum level observed in 40 weeks age group. T3 and T4 hormone were higher in younger age; T3 was highest in 20 weeks while T4 was highest in 1 month age group. Cortisol was higher in older groups and maximum level observed in 40 weeks age group. Among the haematological parameters significant changes was observed in packed cell volume (PCV), white blood cells (WBC), monocyte and neutrophils.

雄性琵鹭出生后发育过程中激素和血液参数变化的估计

背景：对雄性巴提鸭的激素和血液参数进行了研究，以调查这些参数在出生后的发育过程中发生的变化，因为更好地了解生理机能对提高生产力是必要的。研究方法收集巴蒂鸭 1 个月、6-8 周、20 周、30 周和 40 周龄组的血液和血清样本。每个年龄组从颈静脉采集 6 个代表性样本。使用放射免疫分析法（RIA）估测激素（睾酮、皮质醇、三碘甲状腺原氨酸和甲状腺素），并使用数字分析仪研究血液学参数。结果睾酮激素的变化与年龄有关，40 周龄组的睾酮激素水平最高。T3和T4激素在年龄较小时较高；T3在20周龄组最高，而T4在1月龄组最高。较大年龄组的皮质醇水平较高，40 周龄组的皮质醇水平最高。在血液学参数中，观察到包装细胞体积（PCV）、白细胞（WBC）、单核细胞和中性粒细胞有明显变化。
