中文摘要 | 本試驗旨在探討籠飼產蛋菜鴨對有效磷的需要量,基礎飼糧為 CP 18%、ME 2750 kcal/kg, 含鈣量為 3% 之粉料, 試驗組有效磷含量分別為 0.2、0.3、0.4、0.5、0.6 及 0.7% 等六個等級,試驗進行三重複,每處理 10 隻菜鴨,產蛋期 20 週。 結果顯示,有效 磷含量在 0.4~0.6% 者,產蛋率、蛋殼強度及血清中鈣量均較佳,蛋重於含磷組 0.5% 時最 小 (66.35 公克 ),血清中磷量則無明顯差異, 經迴歸計算產蛋率與蛋殼強度, 發現含鈣 3% 之飼糧,有效磷以 0.4 ~ 0.6% 含量時,菜鴨有最佳表現。 |
英文摘要 | The purpose of this experiment was to study the available phosphorus requirements of cage-rearing laying Tsaiya ducks. Basal diets were in mash form which contained crude protein 18%, metabolizable energy 2750 kcal/kg and calcium 3% and was provided for ducks from 20 to 40 weeks of age. This experiment comprised of 6 treatments containing 0.2, 0.3, 0.4, 0.5, 0.6 and 0.7% of available phosphorus. Ten laying Tsaiya ducks in each group with triplicate were in each treatment. The results showed that ducks had higher egg production rate, egg shell strengh and serum calcium concentration when fed diets containing 0.4 ~ 0.6% available phosphorus and 3% calcium. Egg weight was the lowest for ducks consuming diets with 0.5% available phosphorus. However, the feed conversion efficiency were not different among treatments. The serum phosphorus concentrations also were not different. the results suggested that laying ducsks fed diets containing 0.4 ~ 0.6% available phosphorus had maximum egg production rate and egg shell strength. |
