水浴條件及飼養密度對舍飼北京鴨生長性能之影響
The effect of water bath and stocking density on growth performance in Pekin ducks raised inside duck house
摘要
本試驗旨在探討水浴條件及飼養密度對舍飼北京鴨生長性能之影響。北京雛鴨於育雛室飼養至2週齡後逢機分配至室內鴨舍。試驗為水浴條件（有水浴池、無水浴池）及3種不同飼養密度（每平方公尺0.5、1及1.5隻）之複因子試驗，每處理組3重複，試驗共使用18欄。試驗期間測定鴨隻之生長性能、羽毛發育情形及健康評分等性狀（羽毛、眼睛及鼻孔衛生評分）。結果顯示，有水浴池之處理組其鴨隻在7週齡及9週齡時有較高的體重及採食量（P＜ 0.05）；且在9週齡時，有水浴池之處理組其鴨隻主翼羽長度亦較長（P ＜ 0.05）；在健康評分方面，有水浴池之處理組在所有生長階段，皆有較佳之羽毛衛生、眼睛及鼻孔衛生評分。在飼養密度方面，每平方公尺飼養達1.5隻時，對7週齡及9週齡北京鴨之體重、採食量及飼料轉換率無影響（P ＞ 0.05）。本研究之結果顯示，北京鴨飼養於室內時，每平方公尺飼養1.5隻為合理的密度，另提供水浴環境對北京鴨的生長性能有正面效益。

The aim of this experiment was to evaluate the effects of water bath condition and stocking density in indoor duck house on growth performance and health parameters of Pekin ducks. Ducklings were raised in brooding house from hatch to 2 weeks old. Thereafter, ducks were randomly allocated into a duck house. Experiment was a factorial design with main effects of water bath condition (water bath provided with supplemental water trough, no water bath) and stocking density (0.5, 1 and 1.5 duck/m^2). Each treatment had three replicates, a total of 18 pens were used in the experiment. Growth performance, feather development and health parameters (feather hygiene, eyes and nostril hygiene) were measured in the experiment. The results showed that Pekin ducks with water bath had higher (P ＜ 0.05) body weight and feed consumption at 7 and 9 weeks of age. The length of 8th primary wing feather was longer (P ＜ 0.05) on ducks with water bath at 9 weeks of age. Ducks with water bath showed better feather, eyes and nostril hygiene scores. The stocking density had no effect on Pekin ducks' body weight, feed consumption and feed conversion rate during 7 and 9 weeks of age. The results showed that 1.5 duck/m^2 was a reasonable density when Pekin ducks were raised in housing system. Water bath was beneficial for Pekin ducks' performance.
