中文摘要 | 本試驗的目的在於評估飼料中含植酸時中華鱉對於飼料鋅之需求量。中華鱉幼鱉以每公斤含有1%植酸並含有13至177 mg Zn之七組飼料餵飼8週。餵飼控制組飼料(13 mg Zn/kg)之幼鱉成長表現顯著低於其他各組。且其肝臟鋅、血清與背甲鋅含量皆低於餵飼飼料鋅含量高於於40 mg Zn/kg之中華鱉。以多次迴歸模式分析中華鱉在飼料含1%外因性植酸時對鋅之需求量約為每公斤飼料148到157 mg Zn之間,這個含量約為前報中華鱉不含植酸之鋅需求量的3倍。 |
英文摘要 | A feeding trial was conducted to investigate the dietary zinc (Zn) requirements of soft-shelled turtles fed diets containing sodium phytate. Juvenile soft-shelled turtles were fed diets containing 7 levels of Zn (13, 40, 66, 91, 114, 147, and 177 mg kg^(-1)) for 8 weeks. Each diet was also supplemented with 12 g kg^(-1) sodium phytate. Turtles fed the control diet containing 13 mg kg^(-1) endogenous Zn showed lower weight gain (WG), feed conversion ratio (FCR) and protein efficiency ratio (PER) than those fed diets supplemented with Zn (p≤0.05). The Zn contents in liver, serum, and carapaces of the turtles fed low Zn diets (13 and 40 mg kg^(-1)) were lower (p≤0.05) than other groups. In the presence of 1% phytic acid, dietary Zn requirements of juvenile soft-shelled turtles derived from regression modeling with liver, serum and carapace Zn contents as the dependent variables were 157, 148 and 154 mg Zn kg^(-1), respectively. This value is approximately 3 folds of the requirement that has been reported for soft-shelled turtles when phytic acid-free diets were given to the turtles. |
