中文摘要 | 本試驗旨在探討外科去勢對公台灣土雞血液性狀之影響。試驗選用畜試土雞台畜肉十三號公雞176隻,逢機分為去勢與未去勢處理組,每處理四重複,每重複一欄22 隻。雞隻於10 週齡時以外科手術去勢,並餵給生長期飼料(10 至18 週齡)及肥育期飼料(19 至28 週齡),試驗期間每隔2 週每組逢機採血20 隻雞,供測定血液性狀之用。試驗結果顯示,正常公雞之睪固酮(testosterone)、尿酸(uric acid)、總羥脯胺酸(total hydroxyproline)等濃度與血球比容積(packed cell volume)及血漿pH 值顯著(P < 0.05)高於閹公雞,而血漿抑血鈣素(calcitonin)、離子鈣(ionized calcium)、鉀離子(K +)、無機磷(inorganic phosphorus)、總蛋白質(total protein)、白蛋白(albumin)、球蛋白(globulin)、三酸甘油酯(triglyceride)、總膽固醇(total cholesterol)、低密度脂蛋白(low density lipoprotein)與高密度脂蛋白 (high density lipoprotein)等濃度及肌酸激酶(creatine kinase)活性則顯著(P < 0.05)低於閹公雞。血漿甲狀腺素(thyroxine)、副甲狀腺素(parathyroid hormone)、鈉離子(Na +)、氯離子(Cl -)、總鈣(total calcium)、鎂(magnesium)、肌酸酐(creatinine)、尿素氮(urea nitrogen)、乳酸(lactic acid)與游離羥脯胺酸(free hydroxyproline)等濃度及鹼性磷酸酶(alkaline phosphatase)活性,在二者間並無顯著差異。 |
英文摘要 | This experiment was conducted to determine the effect of caponization on blood characteristics of male Taiwan Country Chickens. A total of one hundred and seventy-six 10-wk-old LRI native chicken cockerels, Taishi meat No.13, from LRI-COA were used as experimental animals. Cockerels were surgically caponized at ten weeks of age. Birds were fed grower(10 to 18 wk) and finisher(19 to 28 wk) diet ad libitum during the eighteen week experimental period. Twenty birds from each groups were bleed from 12 to 28 wk of age by 2 wk interval. The results showed that packed cell volume, plasma pH, testosterone, uric acid and total hydroxyproline concentration were significantly (P < 0.05) higher in intact males while capons had a higher (P < 0.05) plasma calcitonin, ionized calcium, K+, inorganic phosphorus, total protein, albumin, globulin, triglyceride, total cholesterol, high density lipoprotein, low density lipoprotein concentrations, and creatine kinase activities. However, the plasma thyroxine, parathyroid hormone, sodium, chloride, total calcium, magnesium, creatinine, urea nitrogen, lactic acid and free hydroxyproline concentrations and alkaline phosphatase activities were not affected. |
