中文摘要 | 本試驗的目的,乃在研究雛土番鴨1-21日齡對組胺酸的需要量。在含有19.1%粗蛋白質的玉米-大豆粕為主的雛鴨實用飼糧(含代謝能2943仟卡/公斤,組胺酸0.475%)中,分別逐級添加結晶形成L-組胺酸-HCl-H₂O,餵飼雛土番鴨,未能改進鴨隻生長和飼料利用效率。本試驗再降低基本飼糧中組胺酸之含量,於是逐級添加組胺酸,餵飼1-21日齡的雛土番鴨。試驗結束後,綜觀雛鴨增重和飼料利用效率之數據,組胺酸的最低需要量約占飼糧的0.244%,即占飼糧粗蛋白質的1.45%。 |
英文摘要 | Growth assays were conducted to determine the requirement of histidine for mule ducklings from 1 to 21 days of age. The results of the first experiment showed that there were no improvements in weight gain and feed efficiency for mule ducklings fed on corn-soybean based diet (crude protein 19.1%, ME 2943 Kcal/Kg, histidine 0.475%) supplementing with graded levels of L-histidine-HCl-H₂O. Therefore, further experiments were designed to lower the content of histidine in the basal diets for mule ducklings. The results indicated that the minimum requirement of histidine for mule ducklings was 0.244% of the diet or 1.45% of the dietary protein. |
