中文摘要 | 本試驗旨在探討籠飼產蛋菜鴨對鈣之需要量,以玉米一大豆粕為主之粉狀基礎飼 糧,含粗蛋白質17.5%,代謝能為2790 kcal/kg,有效磷0.46%,鈣含量分別為2.0、2.5、 3.0、3.5及4.0%等五個處理組,每處理三重複,每重複10隻,試驗為期20週。試驗結果顯 示,產蛋率以3.0%處理組顯著地較3.5%以外之其餘處理組為高(P<0.05)飼料利用效率以3.0% 及3.5%處理組顯著優於其餘處理組,飼料採食量以3.5%處理組顯著低於2.0%處理組。在蛋 殼品質方面,蛋殼強度、蛋殼厚度及殺重百分比以4.0%處理組顯著較佳(P<0.05)。飼糧總磷 為0.60%時,以產蛋率及飼料利用效率之二次迴歸方程式求得籠飼產蛋菜鴨產蛋及飼料利用 效率所需之飼糧鈣含量為3.07%與3.10%。 |
英文摘要 | The purpose of this experiment was to determine the calcium requirement of cage-feeding laying Tsaiya ducks. Corn-soybean basal diet containing CP 17.5%, ME 2,790 kcal/kg, available phosphorus 0.46% was used and the calcium levels were assigned at 2.0, 2.5, 3.0, 3.5 and 4.0% of the diets, respectively for each treatment. One hundred and fifty Tsaiya ducks in triplicate per treatment with 30 Tsaiya ducks were used in this experiment and the experiment was performed from 25 to 45 weeks of age for 20 weeks. The results indicated that egg weights were lower in the 3.0 and 3.5% treatments. Body weight changes were significantly different among treatments. Tsaiya ducks fed diet with 3.0% of calcium had higher egg production than other treatments except that of 3.5% treatment. The feed efficiency of 3.0 and 3.5% treatments were better than the other treatments. Egg shell quality including egg shell strength, egg shell thickness and percentage of egg shell weight was significantly higher in the 4.0% treatment. In conclusion, the calcium requirements of cage-feeding for egg production and feed efficiency were 3.07% and 3.10% according to the quadratic regression equation, respectively. |
