中文摘要 | 本研究旨在比較不同種別、性別及飼養期長度對家禽脂質蓄積相關性狀之差異, 分成三個試驗, 試驗一乃以 16 週齡之雌性白色肉雞、臺灣土雞、 火雞及來航未產蛋雞各 20 隻為試驗動物; 試驗二以 16 週齡之雄性及雌性臺灣土雞各 20 隻為試驗動物;試驗三 以 6 週齡及 16 週齡之白色肉雞各 20 隻為試驗動物。 試驗雞隻予以採血並取其腹脂以測 定脂質蓄積之相關性狀。 試驗一之結果顯示,脂蛋白脂解�t (LPL) 之活性以未產蛋雞最低 ,且與其他三種肉用雞間有顯著之差異 (P<0.05)。賀爾蒙敏感脂解�t (HSL) 活性以火雞 > 肉雞 > 未產蛋雞 > 土雞,且品種間有顯著之差異 (P<0.05)。 LPL:HSL 之比值則以土雞最 高,且與其他三品種間有顯著差異 (P<0.05),血中 VLDL 濃度以未產蛋雞與肉雞 > 土雞 > 火雞, 其間也有顯著差異 (P<0.05)。 血中之三酸甘油酯 (TG) 濃度為土雞 > 未產蛋雞 > 肉雞 > 火雞,其間也皆有顯著之差異 (P<0.05)。而腹脂含量佔體重之百分比則以土雞最高 ,且與其他三種家禽間有顯著之差異 (P<0.05), 而未產蛋雞最低,與土雞及肉雞間有顯著 之差異 (P<0.05)。試驗二之結果顯示,性別間除了 LPL:HSL 之比值無顯著差異外,其他性 狀皆以雌性土雞高於雄性土雞 (P<0.05)。 試驗三之結果顯示, 16 週齡時白色肉雞之 LPL 及 HSL 活性皆高於 6 週齡者 (P<0.05);但 LPL:HSL 比值則反之 (P<0.05);血中 VLD 之 濃度 6 週齡者低於 16 週齡者 (P<0.05); 腹脂佔體重之百分比以 6 週齡者高於 16 週齡 者 (P<0.05)。 而以迴歸預估腹脂量之公式,雌性臺灣土雞為 3.63-0.15 LPL/HSL (r �� = 0.11); 雄性臺灣土雞為 0.28+0.03 VLDL (r �� =0.14); 而火雞為 1.91-0.01 TG-0.04 VLDL (r �� =0.34)。 |
英文摘要 | The purpose of this study was to compare different kind, sex and feeding period on abdominal fat accumulation related traits of avians. In Trial one, we used twenty 16-week-old female broilers, Taiwan country chickens, turkeys and Leghorn layer chickens pullets as experiment animal. In Trial two, twenty 16-week-old of male and female Taiwan country chickens were used, and twenty 6 weeks and 16 weeks old broilers were used in Trial three. Blood and abdominal fat samples were taken for analysis. The result of trial one showed that pullets had the lowest LPL activity, and was significantly different with the other three kind of avians (P<0.05). HSL activity results were turkeys>broilers> pullets>Taiwan country chickens, and exhibited markedly different among avians (P<0.05). Taiwan country chicken had the highest LPL:LSL ratio, and was significantly different from other avians (P<0.05). Serum VLDL concentration displayed that pullets or broilers >Taiwan country chickens > turkeys, and there also had significant difference among avians (P<0.05). Serum TG level showed that Taiwan country chickens > pullets > broilers > turkeys, and significant differences were observed among avians (P<0.05). As for the percentage of abdominal fat exhibited that Taiwan country chicken was the highest, and was significantly different with other avians (P<0.05); pullets was the lowest and showed markedly different from the Taiwan country chickens and broilers (P<0.05). The results of trial two exhibited that almost determined traits in female Taiwan country chickens were greater than male's (P<0.05), except the LPL:HSL ratio. The results of trial three displayed that LPL and HSL activities in 16-seek-old broilers was greater than that in 6 weeks (P<0.05). On the other hand, LPL:HSL ratio at 6 weeks was higher than (P<0.05); alternatively, the percentage of abdominal fat in 6 weeks was greater than in 16 weeks (P<0.05). The regression model to predict the abdominal fat, was 3.63-0.15 LPL/HSL (r �� =0.11) in female Taiwan country chickens; and was 0.28+0.03 VLDL (r �� =0.14) in male Taiwan country chickens; and was 1.91-0.01 TG-0.04 VLDL (r �� =0.34) in turkeys. |
