中文摘要 | 16頭臺灣黑山羊離乳仔羊逢機分為兩組,每組兩重覆置於群飼欄飼養。A組餵以玉 米啤酒粕及蔗渣之青貯料與苜蓿粒,而B組則餵以玉米及大豆粕為主之精料與苜蓿粒。以評估 利用啤酒粕及蔗渣飼養肉羊降低飼料成本之可行性。試驗資料顯示,兩組山羊平均每日增重、 乾物質飼料採食量及飼料換肉率均無顯著差異。唯在每公斤增重之飼料成本方面,A組為37.0 元,而B組為47.5元。 在活體消化試驗及山羊瘤胃揮發性短鏈脂肪酸產量與分佈方面,兩組山羊也無組間差異存 在。在分析血液生化值方面,試驗組的天門冬胺酸轉胺□(AST),血液中尿素氮的含量(BUN)均 比對照組高,且有統計差異(P<0.05),而其中只有試驗組的天門冬胺酸轉胺□超過了標準值 外,其他還在容許範圍之內。在血液含蛋白及鈣量方面兩組之值相近,而且介於標準值之內。然在 血液含磷量方面,試驗組比對照組高且有組間差異存在,而其值也超過標準值外。在屠體評估 方面,試驗組與對照組的屠宰率、精肉率、屠體含脂率分別為47%、48.5%,30.2%、31.8%及 6.1%、6.0%;唯均無差異存在。在每公斤精肉生產價格方面,試驗組為139.7元而對照組為 184.9元,有統計上差異存在。 |
英文摘要 | A total of sixteen crossbred Nubian and Taiwan native goats were randomly allocated into two groups which were fed either with corn-brewer's grain-bagasses silage and alfalfa pellet as ration A, or with concentrate and alfalfa pellet as ration B. Results showed that there were no difference on daily dry matter intake, daily weight gain or feed efficiency between the two treatments. Nevertheless, the cost of per kg live weight gain of goat in ration A were significantly lower than in ration B (37.0 vs 47.5 N.T. dollars) (P<0.05). The in-vivo and in-vitro experiments result showed no difference in dry matter, nitrogen, NDF and ADF digestibility between the two rations. There were significant difference in the value of AST, BUN, protein, calcium and phosphorus between the groups (P<0.05). There were also no difference in dressing percentage, lean meat percentage and fat percentage of carcasses between two treatments. Nivertheless, there were significant difference in the cost of meat production between the treatments. |
