中文摘要 | 本研究之目的在探討土番雛鴨之核黃素缺乏症狀及其需要量。 試驗一,以玉米澱粉一分離大豆蛋白質型半純化低核黃素飼糧,來餵飼雛土番鴨,觀察核黃素之缺乏症狀。試驗二至四,以低核黃素飼糧輔於不同水平之核黃素來餵飼土番鴨,求土番鴨之核黃素需要量。 供試動物為購自商業孵化場之一日齡土番鴨。土番鴨之核黃素缺乏症狀為採食量降低,生長遲緩,甚至死亡。 核黃素需要量之測定,係以土番雛鴨之增重對飼糧中核黃素含量做直線迴歸分析,在3-21日齡時之核黃素最低需要量為4.60 ppm飼糧。 |
英文摘要 | Four feeding trials were conducted to achieve two goals. The first was to observe the symptoms of riboflavin deficiency in mule ducklings fed diet deficient in riboflavin. The second was to determine the riboflavin requirement of mule ducklings based on growth rate. In experiment 1, growing mule ducklings were given a corn starch-isolated soybean protein type low-riboflavin semipurified diet to observe the symptoms of riboflavin deficiency. In experiments 2, 3, and 4, experimental birds were given low-riboflavin semipurified diet supplemented with graded levels of riboflavin to detemine the riboflavin requirement for best gain of body weight. In all experiments, day-old mule ducklings obtained from a commercial hatchery were used. The symptoms of riboflavin deficiency in mule ducklings observed were decreased feed intake, retarded growth and death. The requirement for riboflavin was obtained by using regression analysis on body weight gain of mule ducklings against on riboflavin content in the diet. The result showed that the minimum requirement of riboflavin for mule ducklings from 3-21 days of age was 4.60 ppm in the diet. |
