飼糧添加生鮮狼尾草台畜草三號對白羅曼鵝生長及屠體性狀之影響
The effect of feeding green Napiergrass Taishigrass No.3 on growth and carcass characteristics of White Roman geese
摘要
本文主旨為探討肉鵝飼糧餵量與添加生鮮狼尾草台畜草三號對其生長性能與屠體性狀之影響。試驗採用192隻商用肉雛鵝，公、母各半，依性別逢機分配至12欄，每欄16隻，公與母雛鵝各為8隻。12欄鵝隻依完全逢機設計分配基礎飼糧組、基礎飼糧添加狼尾草台畜草三號（J.Cv.TLG3）牧草任飼組、1/3牧草任飼組及2/3牧草任飼組等4種處理。結果顯示，鵝隻餵飼基礎飼糧（對照組）之3－12週齡體增重，顯著較餵飼基礎飼糧添加J.Cv.TLG3牧草任飼組、1/3牧草任飼組及2/3牧草任飼組者重（4.76vs.4.54、4.57及4.51kg/bird; P＜0.05）。鵝隻餵飼基礎飼糧添加J.Cv.TLG3牧草任飼量、1/3及2/3牧草任飼量組之肌胃重，顯著較餵飼基礎飼糧組者為重（231、214及230vs.181g/bird; P＜0.01）；然於腹脂重則反之（165、160及160vs.203g/bird; P＜0.05）。鵝隻餵飼基礎飼糧之胸皮重，顯著較餵飼基礎飼糧添加J.Cv.TLG3牧草1/3及2/3牧草任飼組者為重（289vs.248及255g/bird; P＜0.05）。綜合上述資料顯示，3至12週齡鵝隻餵飼基礎飼糧添加J.Cv.TLG3牧草之體增重明顯較對照組者輕，然3－13週齡時，各處理組則無差異。鵝隻餵飼基礎飼糧添加J.Cv.TLG3牧草之腹脂重及胸皮重較輕，顯示鵝隻餵飼基礎飼糧添加牧草時，會減少其能量攝取量，降低體脂肪之堆積。

The purpose of this study was to investigate the effect of feeding Napiergrass Taishigrass No.3 (J.Cv.TLG3) on growth performance and carcass quality of White Roman geese. The experiment was a completely randomized design and geese were randomly assigned into four treatments i.e. basal diet (Control), basal diet plus green Napiergrass Taishigrass TG3 ad libitum, 1/3 J.Cv.TLG3 ad libitum and 2/3 J.Cv.TLG3 ad libitum. A total of one hundred and ninety-two geese were randomly allotted into four dietary treatments, each including 3 pens and each pen with 8 males and 8 females. The results showed that the geese feeding basal diet supplemented with green J.Cv.TLG3 ad libitum, 1/3 J.Cv.TLG3 ad libitum and 2/3 J.Cv.TLG3 ad libitum had lighter body weight than control group during 3 to 12 week (4.54, 4.57 and 4.51 vs. 4.76 kg/bird, P ＜ 0.05). Geese feeding basal diet plus J.Cv.TLG3 ad libitum, 1/3 J.Cv.TLG3 ad libitum and 2/3 J.Cv.TLG3 ad libitum have heavier gizzard weight than those of control (231, 214 and 230 vs. 181 g/bird; P ＜ 0.01). However, the weight of abdominal fat pad were 165, 160 and 160 vs. 203 g/bird, respectively. The geese fed the basal diet have heavier skin weight of breast than other treatments (203 vs. 165, 160 and 160 g/bird, P ＜ 0.05). In conclusion, geese fed basal diet plus J.Cv.TLG3 grass have larger body weight gain during 3 to 12 week of age, but not at 3 to 13 week old. Geese fed basal diet plus J.Cv.TLG3 grass had lighter abdominal fat pad weight and skin weight of breast.
