| 中文摘要 | 本研究旨在確定年齡和性別（週數）對白羅曼鵝生長、屠體表現和羽毛品質的影響，並分析年齡和性別（週數）對鵝羽毛特性的相對影響。 在動物實驗中，將120 隻13 週齡的白羅曼鵝隨機分佈在12 欄中，每個欄包含10 隻雄性或10 隻雌性，完全隨機設計。於 13、15、17、19、21、23 和 25 週齡犧牲 10 隻鵝。 結果顯示，年齡對鵝體重（BW）無顯著影響（P>0.05）。 21至25週齡鵝的胸圍明顯長於13至19週齡鵝（P < 0.05）。 13週至25週齡組的生長鵝體重量沒有顯著變化（P > 0.05）。 25週齡各組下降百分比顯著高於13週齡組、15週齡組及17週齡組（P < 0.05）。 雄鵝的乾羽毛重高於雌鵝（P < 0.05）。 生長鵝的 18 小時禁食體重（18 小時 FDBW）和 4 至 10 公分羽毛重量呈顯著負相關（-0.42）。 這為羽毛產業提供了更好地利用養殖鵝副產品的機會。 總之，年齡對 13 至 25 週大鵝的體重沒有影響，並且在 25 週齡時觀察到良好的絨毛率和乾重。 生長鵝的 18 小時 FDBW 和下降百分比呈現顯著負相關（-0.55） |
| 英文摘要 | This study aimed to determine the effect of age and sex in weeks on growth, carcass performances, and feather quality of White Roman geese and analyze the relative effect of age and sex in weeks on feather characteristics in geese. In animal experiments, 120 White Roman geese aged 13 wk were randomly distributed among 12 pens and fed grower diet ad libitum during the growing period, with each pen containing 10 males or 10 females, depending on a completely random design. Ten geese each in their 13, 15, 17, 19, 21, 23, and 25 wk of age were sacrificed. The results showed that the age had no significant effect on the body weight (BW) of geese (P > 0.05). The chest girth was significantly longer in 21 to 25 wk old than in 13- to 19-wk-old geese (P < 0.05). The results reveal no significant change in carcass weight of grower geese among 13- to 25-wk age groups (P > 0.05). The down percentage of the 25-wk-old age group was significantly higher than that of the 13-, 15-, and 17-wk age groups (P < 0.05). The male geese had a higher dry feather weight than the females (P < 0.05). Similarly, the 18-h feed-deprived body weight (18-h FDBW) and 4 to 10 cm feather weight were significantly negatively correlated in grower geese (-0.42). This provides the feather industry an opportunity for the better utilization of grower geese by-products. In conclusion, the age has no influence on BW among 13- to 25-wk-old geese, and a good down percentage and dry weight were observed at 25 wk of age. The 18-h FDBW and down percentage had a significantly negative correlation (-0.55) in grower geese. |
