摘要

本試驗旨在比較產青殼蛋與產白殼蛋之褐色菜鴨在產蛋期之血球相。以生產青殼與白殼蛋二個菜鴨品系體重相近之9月齡菜鴨各10隻，供試菜鴨採個別籠飼，飼料與飲水採任食。分別於菜鴨10、11與12月齡時自翼靜脈採血，備供測定血液之紅血球相與白血球相。結果顯示，10到12月齡鴨隻紅血球總數與血容比平均值，均以產青殼蛋之菜鴨顯著高於產白殼蛋之菜鴨（P＜0.05），而產白殼與產青殼蛋兩個品系之褐色菜鴨之血紅素、平均紅血球血紅素量與平均紅血球血紅素濃度，則無顯著差異。在試驗期中，兩個品系褐色菜鴨的紅血球總數均隨月齡之增加而增多（P＜0.05）。在白血球相方面，產白殼蛋鴨隻之淋巴球比值在12月齡時，顯著高於產青殼蛋者（P＜0.05）。但二個菜鴨品系之間的血液單核球、嗜鹼性白血球及嗜酸性白血球比例值，在10到12月齡間無顯著差異。由試驗結果顯示，兩個菜鴨品系合併之異嗜性白血球（H）／淋巴球（L）之比值主要受月齡之影響；此外，基於血液H／L之比值為動物緊迫指標，在10月齡時，異嗜性白血球百分比值與H／L之比值為最高（P＜0.05），推測此結果可能與鴨隻受到熱季高溫緊迫有關。

The purpose of present study is to compare the erythrocyte and leukocyte profile in white-eggshell and blue-eggshell of Brown Tsaiya duck at laying period. Each of ten white-eggshell and blue-eggshell female Brown Tsaiya ducks at their 9 months of age were used in this study. Birds were kept in individual cage and feed and water were supplied ad libutum. At 10, 11 and 12 months of age, blood of ducks were collected measurements. The results showed that blue-eggshell ducks had higher total red blood cell (RBC) count and packed cell volume than white-eggshell duck during 10-12 months of age (P ＜ 0.05). Nevertheless, there are no significant difference in hemoglobin, mean corpuscular volume mean corpuscular hemoglobin and mean corpuscular hemoglobin concentrations were found between the white-eggshell duck and blue-eggshell duck. The total red blood cell count increased with age in both of Tsaiya duck strains during the whole experimental period (P ＜ 0.05). The white-eggshell ducks had higher lymphocyte differential count percentage than that of blue-eggshell ducks at 12 months of age; however, there were no significant differences in the differential count percentage of monocytes, basophils and eosinophils between the white-eggshell ducks and blue-eggshell ducks at 10, 11 and 12 months of age. The brown Tsaiya ducks had a highest heterophils/ lymphocyte (H/L) ratio at 10 month-old of age. Based on the viewpoint that H/ L ratio interpret as the animal stress indicator, it is suggested that the brown-eggshell ducks is more stressful than the white-eggshell ducks. Moreover, the highest H/L ratio in both strains of ducks at 10 month-old indicating ducks may suffer greater physiological stress while in the hot season.
