論文摘要內容：
本論文旨在探討飼糧中使用棕櫚仁粕(palm kernel meal)取代苜蓿粉對紐西蘭白兔之生長、屠體性狀與肉質特性等產肉性狀之影響。48隻40日齡之紐西蘭白兔，公母各半，試驗開始前秤量其活體重，再以體重完全逢機分配方式至控制組（飼糧中不含棕櫚仁粕），含20％棕櫚仁粕組及40％棕櫚仁粕組，試驗兔隻分別飼養在獨立飼養籠中，籠舍中均有個別飼料槽和飲水器，試驗期間為8週(試驗一)或13週(試驗二)，試驗期間每日餵飼一次給予任飼，每週紀錄其採食量，於第8週時秤量試驗兔隻活體重，以計算體增重，飼料轉換率，並計算其生產成本（試驗一）。於第8週及13週各組分別取8頭兔隻予以人道犧牲，犧牲後隨即放血並秤重，續將其毛皮和頭部，內臟和四肢分離後隨即秤其屠體重，屠體的部分則分別秤量心臟，肝臟，以及里肌肉、腿肉等各部位屠體肉（試驗一）。並分析屠肉色澤，截切值，熟煮失重等檢測項目（試驗二）。各項數據以一般線性模式進行變方分析，再以單因子變異數分析檢測試驗間之差異顯著性。試驗結果顯示：飼糧中以棕櫚仁粕取代苜蓿粉之添加使用，飼養8週對於紐西蘭白兔之體重，體增重和試驗期間之飼料效率、增重成本及屠體性狀與對照組無顯著差異（試驗一）。飼養13週後所取得屠體及屠肉之理化性狀分析方面，其整體和性別間之屠肉重量亦無明顯差異（試驗二）。而飼料中含有棕櫚粕取代20%或40%苜蓿粉，其飼料價格較低於控制組飼料。尤以40%棕櫚仁粕取代苜蓿粉，較有降低飼糧成本，且不影響兔隻性別之生長性能、屠體性狀及其肉質特性(理化及感官品評特性等)。綜合本試驗結果，飼糧中以20-40％的棕櫚仁粕取代苜蓿粉，不影響紐西蘭白兔之產肉效率與肉質，並可降低兔隻飼糧成本，進而增加兔農之收益。

The Contents of Abstract in this thesis:
This study was aimed to investigate the effect of partly substitution of alfalfa meal with palm kernel meal on growth performances and meat quality of White New Zealand rabbits. Forty six (48) White New Zealand rabbits, 40 days old of age, male and female were used. Before the trial began, weighing their live weight, every machine in order to complete the weight distribution to the control group (diet excluding palm kernel meal). The experimental diets were contained 20 % palmitic kernel meal and 40 % of palm kernel meal. The rabbits were reared in battery cage with individual feeder and drinker. With eight rabbits in each group. The duration of experiment was 8 weeks and 13 weeks. The feed was given weekly and feed intake was recorded daily. Body weight gain, feed conversion, and production cost was recorded at 8 weeks (Test 1). At the end of the experiment, all rabbits in each group were humanely sacrificed, bled immediately, and weighed after sacrifice, to acquire carcass weight after bloodletting and the weight immediately after their fur and head. Internal organs and limbs were separated from the body. Weighing the heart, liver, fillet, leg meat carcasses and other ministries. The fillet was used for analyzing the fleshy color, clipping value, and cooking weight loss (Test 2). The data was analyzed by the general linear model (GLM) variant analysis of ANOVA. The significant differences between means was analyzed by New Duncan’s Multiple Range Test. The results showed that there was no significant difference of using palm kernel meal to substitute alfalfa leaf powder compared to the control group. In the analysis of meat (carcass yield), no significant difference was found in the treatment, while feed containing palm kernel meal showed lower feed cost production compared to the control group. Comprehensive results of this study, 20-40 % of palm kernel meal in did not affect the meat production efficiency, and reduced the cost of the rabbit diet, thereby increasing the revenue of rabbit farming.
