中文摘要 | 本試驗之目的為評估提高飼糧營養濃度對土番鴨抗熱緊迫之效果。試驗分三處理,分別為適溫商用飼糧組 ( 對 照組 )、高溫商用飼糧組與高溫高營養濃度飼糧組。試驗鴨隻飼養於可設定環境溫度與濕度的人工氣候室內。試驗 測定項目包含體重、飼料採食量與飼料轉換率等生長性狀;屠體重、屠宰率、腹脂重、胸肉一般組成分等屠體性狀, 試驗處理為期六週。結果顯示,不同處理組在試驗期間體重無顯著差異;飼料消耗量以適溫組鴨隻採食量最高,而 高溫高營養濃度飼糧組則顯著減少飼料採食量 (P < 0.05),且有最佳的累積飼料轉換率 (P < 0.05)。屠體性狀方面:於 鴨隻 10 週齡時,對照組具有顯著較高的屠宰率 (P < 0.05);然而在胸肉近似分析則無顯著差異。綜合試驗結果顯示, 提高飼糧營養濃度可降低炎熱環境下鴨隻的採食量並改善飼料轉換率,但對於鴨隻的體重則沒有顯著的影響。 |
英文摘要 | The purpose of this experiment was to evaluate the effects of raised nutrient concentration diet on alleviating heat stress in mule ducks. There were three treatments in the experiment, optimal temperature with commercial diet treatment as control group, high ambient temperature with commercial diet and high ambient temperature with raised nutrient concentration diet respectively. Ducks were bred in an artificially controlled climate chamber. Determined traits were described as following: growth traits: body weight, feed intake, carcass weight, dressing percentage, abdominal fat weight and breast proximate chemical composition. The experiment lasted for six weeks. The results indicated that no significant difference was found on body weight between treatments. However, ducks bred in optimal temperature consumed most and high ambient temperature with raised nutrient concentration consumed less feed significantly (P < 0.05), which resulted in better feed conversion ratio (P < 0.05). In the carcass traits, optimal temperature with commercial diets group showed higher dressing percentage when ducks were sacrificed at 10 weeks of age (P < 0.05), nevertheless, no significant differences were found on breast proximate chemical composition. In conclusion, to feed ducks raised nutrient concentration under heat environment could improve feed conversion ratio, but no significant influence was found on ducks’ body weight. |
