中文摘要 | 本試驗之目的在探討產蛋菜鴨對異白胺酸之需要殘,並測定飼糧異白胺酸含量對鴨隻之產蛋性能、蛋殼品質、血漿與蛋中支鏈胺基酸濃度及繁殖性狀之影響。試驗以玉米-大豆粕為主之基礎飼糧,含白胺酸1.46%、異白胺酸0.50%及纈胺酸0.86%,另逐級添加L-異白胺酸0、0.10、0.20、0.30、0.40及0.50%。各處理組飼糧之粗蛋白質均為17%,代謝能為2750 kcal/kg 試驗為期20週。試驗結果顯示,飼糧異白胺酸含時,產蛋率顯著地較0.50%處理組佳(P<0.05),其中以0.90%處理組之產蛋率最高。 在蛋殼品質與受精率及孵化率方面,各處理組間皆無顯著差異,飼糧中異白胺酸含量對血漿中白胺酸、異白胺酸及纈胺酸濃度為無顯著影響,血漿中異白胺酸濃度隨著飼糧異白胺酸含量之提高而上昇,而以0.90%處理組之血漿中白胺酸、異白胺酸及纈胺酸濃度均較其餘處理組為高,但無顯著差異,蛋中之白胺酸、異白胺酸與纈胺酸之含量於各處理組間均無顯著差異。 |
英文摘要 | The purpose of this experiment was to determine the isoleucine requirement of laying Tasiya duck. Conr-soybean basal diet which contain CP 17%, ME 2750 kcal/kg, Ca 3.0%, available phosphorus 0.46%, leucine 1.46%, isoleucine 0.50% and valine 0.86% was used. Graded levels of L-isoleucine at 0、0.10、0.20、0.30、0.40 and 0.50% were added to the basal diet. Three hundred and sixty Tsaiya duck (2♂+18♀) in triplicates per treatment were used for 20 weeks. The results indicated that egg weight, feed conversion and body weight change were not significantly different among treatments. The diet containing 0.80% isoleucine had better egg production than the 0.50% treatment (P<0.05). The egg shell quality, fertility and hatchability were not different among treatments. The concentration of plasma isoleucine tended to increase as the dietary isoleucine levels increased. The contents of leucine, isoleucine and valine in egg were not different among treatments. |
