以三個試驗探討使用狼尾草調配完全混合日糧（Total mixed ration; TMR）餵飼白羅曼鵝，對其生長、消化道與羽毛性狀之影響。試驗一以216隻一日齡雛鵝區分為四個處理組，分別為對照組、飼糧添加大麥糠組、全期飼糧添加狼尾草組及0-8週齡飼糧添加狼尾草，9-13週齡餵飼對照組飼糧之處理組。試驗二168隻14日齡雛鵝區分為對照組及飼糧中狼尾草之添加量分別為20%、40%、50%等四個處理組。試驗三以144隻6週齡鵝隻逢機分為對照組及飼糧中狼尾草之添加量分別為33.3%、40%、50%等四個處理組。三個試驗各處理組均為三重複，試驗飼糧均調配為等熱能與等蛋白質，調配飼糧時，狼尾草以風乾物計算，飼料與水採任食。試驗期間測定採食量、體重、飼料轉換率、腸道性狀與進行羽毛發育之觀察。結果顯示，新鮮狼尾草在TMR中佔50%以上時，鵝隻全期之採食量較對照組為低，鵝隻早期之體增重亦較差，但飼料轉換率則有較佳之現象；餵飼狼尾草鵝隻早期消化道發育較快。添加大麥糠與狼尾草提高粗纖維含量達6%之TMR組鵝隻在4及8週時無啄毛現象，但對照組則啄毛嚴重；8週齡時對照組鵝隻身體羽毛外觀呈現波浪狀翹起且無光澤，TMR組則無啄毛，且身體羽毛外觀平順有光澤。綜合上述，新鮮狼尼草在TMR中佔50％時，雖然鵝隻會降低採食量及減少早期體增重，但仍有較佳飼料轉換率及促進鵝隻早期消化道發育。此外，亦會改善因飼糧粗纖維含量不足所引起生長鵝之啄羽現象。

Three trials were conducted to investigate the effect of total mixed ration (TMR) used Napier grass as forage source, on the growth performance, digestive tract and feather trait in white Roman geese. In trial 1, two hundred and sixteen of days old goslings were divided into four treatments. Four treatments included: (1) goslings fed concentrate diet as control; (2) goslings fed TMR containing barley hull; (3) goslings fed TMR containing Napier grass; (4) goslings fed TMR containing Napier grass from 0 to 8 weeks of age and fed concentrate diet from 9 to 13 weeks of age. In trial 2, one hundred and sixty-eight of 14-day-old goslings were divided into four treatments. Four treatments included: (1) goslings fed concentrate diet as control; (2) goslings fed TMR containing 20% Napier grass; (3) goslings fed TMR containing 40% Napier grass; (4) goslings fed TMR containing 50% Napier grass. In trial 3, one hundred and forty-four of 6 weeks of age goslings were divided into four treatments again. Four treatments included: (1) goslings fed concentrate diet as control; (2) goslings fed TMR containing Napier grass 33.3%; (3) goslings fed TMR containing Napier grass 40%; (4) goslings fed TMR containing Napier grass 50%. There were three replicates for each treatment of three trials. Goslings fed isocaloric, isonitrogenous diets. Feed and water were supplied ad libitum. The results indicated that goslings fed TMR containing Napier grass level over 50% had lower feed intake and body weight gain than those fed control diet. However, the feed conversion ratio was improved and the development of digestive tracts was more fast. No cannibalism phenomenon was found in goslings received Barley hull and TMR containing Napier grass but there was a serious peck feather phenomenon in goslings received the control diet. Based on the above, when fresh Napier grass level for 50% of the TMR, although it will reduce the feed intake and early body weight gain of goslings, they still have a better feed conversion ratio and promote the early digestive tract development of geese. In addition, suppling Napier grass will also improve the feather pecking phenomenon because of insufficient crude fiber content in diet for goslings.
