飼糧粗纖維與粗蛋白質含量對種母鵝產蛋性能與血液性狀之影響

本試驗旨在探討休產期飼糧粗纖維含量（10或15%）及產蛋期飼糧粗蛋白質含量（15或18%）對白中國鵝（White Chinese geese）及白羅曼鵝（White Roman geese）第二產蛋期產蛋性能與血液性狀之影響。各品種均選取種鵝112隻、各分配至2個飼糧粗纖維含量（10%或15%）處理組、每處理4欄，每欄3♂、11♀，以調查休產期不同飼糧粗纖維含量對種母鵝再產之影響。俟各處理組產蛋率達5%後，再分為兩粗蛋白質含量之處理，每處理2欄，分別餵以15%或18%粗蛋白質含量飼糧，以比較產蛋期不同粗蛋白質含量對種鵝第二產蛋期繁殖性能之影響。結果顯示，休產期飼糧粗纖維含量（10%或15%）對處理與品種間之飼料採食量影響皆不顯著（p＞0.05）。白中國鵝再產日齡較白羅曼鵝早（P＜0.05），再產體重也較白羅曼鵝輕（P＜0.05）。白中國鵝15%飼糧粗纖維處理組之血清鹼性磷酸酶及三酸甘油酯濃度顯著（P＜0.05）高於白羅曼鵝10%或15%飼糧粗纖維處理組。產蛋期飼糧粗蛋白質含量對處理與品種間之飼料採食量、受精率、孵化率、平均每隻母鵝之產蛋數及出雛數影響皆不顯著（P＞0.05），白羅曼鵝15%或18%飼糧粗蛋白質處理組，其再產及結束體重顯著（P＜0.05）高於白中國鵝15%或18%飼糧粗蛋白質處理組。白羅曼鵝18%飼糧粗蛋白質處理組之血清鹼性磷酸酶濃度顯著（P＜0.05）高於白中國鵝18%飼糧粗蛋白質處理組。白中國鵝之月高峰產蛋率為23.01%、白羅曼鵝則為29.95%，分別在2月或3月達產蛋高峰。

The experiment was conducted to evaluate the effects of resting period dietary crude fiber (CF) contents (10% or 15%) and laying period dietary crude protein (CP) contents (15% or 18%) on laying performance and blood Characteristics of the second laying White Chinese geese and White Roman geese. One hundred and twelve birds per breed were assigned into two treatment groups containing 10% or 15% CF diets, respectively. Each group had four replicated pens and the experiment was conducted to examine the effects of resting period dietary CF at the onset of laying performance. After the laying rate reached 5%, each treatment was further given two levels of CP (15% or 18%) diets to determine the effects of laying period dietary CP on reproductive performance through the second laying period. The results indicated that dietary CF levels had no effect (P＞0.05) on feed intake for treatments or breeds during resting period. White Chinese geese were earlier (P＜0.05) in age and lower at body weight than White Roman geese at the onset of the second laying period. White Chinese geese fed 15% CF were higher (P＜0.05) in serum alkaline phosphatase (ALP) and triglyceride than White Roman geese fed 10% or 15% CF. Dietary CP in laying period also had no effect (P＞0.05) on feed intake, fertility, hatchability, number of eggs and goslings per goose for treatments or breeds during laying period. White Roman geese fed 18% CP were higher (P＜0.05) in serum ALP than White Chinese geese fed 18% CP. The peak of laying was 23.01% (in February) for White Chinese geese and 29.95% (in March) for White Roman geese, respectively.
