中文摘要 | 本試驗採用10頭約七月齡之臺灣黃牛離乳仔公牛,逢機分為兩組,每組五頭,分置於個別飼養欄飼養。試驗組餵以米酒糟蔗渣青貯料與精料,而對照組則餵以青貯盤固草與精料。試驗顯示,試驗組與對照組之黃牛,其平均每日增重、乾物質飼料採食量及乾物質飼料換肉率,分別為0.9 kg、4.5 kg、5.0 vs 1.0 kg、5.0 kg、5.0,其組間均無差異存在。唯在每公斤增重之飼料成本方面,試驗組與對照組分別為38.3元與41.3元,試驗組每公斤增重之飼料成本顯著低於對照組(P<0.05)。 在活體消化試驗方面,兩組黃牛消化率也無組間差異。在分析黃牛血液生化值方面,試驗組的麩胺酸草醯乙酸轉胺?(GOT),血液中尿素氮(BUN)的含量與對照組相似,且其值在標準範圍之內。在血液含蛋白、鈣量及磷量方面兩組之值亦相近,而且同樣介於標準值之內,兩組黃牛亦均無組間差異。在屠體評估方面,兩組之屠宰率、屠體精肉率與體脂肪率,分別為58.7%、66.7%、14.7% vs 59%、66.3%、14.8%,其組間均無差異。在生產每公斤精肉之飼料成本方面,試驗組與對照組分別為97.7元與105.6元,試驗組每公斤精肉生產成本顯著低於對照組(P<0.05)。 |
英文摘要 | A total of ten head Yellow Cattle were randomly allocated into two groups which fed either with distilled rice grain with bagasses silage and concentrate as ration A or with Pangolagrass silage and concentrate as ration B. Results showed that there were no significant differences on daily dry matter intake, daily gain weight and feed efficiency between two rations. Nevertheless, the cost of per kg weight gain of cattle in ration A was significantly lower than that of in ration B (38.8 vs 41.3 N.T. dollars) (P<0.05). On in-vivo experiment results, there were no differences in dry matter, nitrogen, NDF and ADF digestibility between two rations. There were also no significant differences on the value of Glutamic-oxaloacetic transaminase (GOT), Blood urea nitrogen (BUN), protein, calcium and phosphorus in the blood of cattle between two groups. Furthermore, there were no significant differences in the slaughter traits between two groups, except the cost of per kg meat production. |
