Abstract

Four Zebu and four Simmental oxen were submitted to moderate and exhaustive work. Venous blood samples were taken before, immediately after and 30 min after work and assayed for several blood parameters. 2. Draught work led to a decrease in carbon dioxide (pvCO2) and increases in pH, oxygen (pvO2), triglycerides, free fatty acids (FFA) and lactate. 3. Zebu oxen had higher pvCO2 and FFA and lower pH, pvO2 and lactate in response to exercise. 4. Ratios of individual draught power output and values of pvO2 and lactate after work enable the identification of fit and/or weak individuals.

摘要

四头瘤牛和四头西门塔尔牛分别进行适度劳作和高强度劳作。在劳作前、劳作刚结束时以及劳作结束30分钟后采集静脉血样本，并对多项血液参数进行检测。2. 牵引劳作导致二氧化碳（pvCO2）含量降低，pH值、氧气（pvO2）、甘油三酯、游离脂肪酸（FFA）和乳酸含量升高。3. 瘤牛在运动后pvCO2和FFA含量较高，而pH值、pvO2和乳酸含量较低。4. 根据个体牵引功率输出以及劳作后pvO2和乳酸的值，可以识别出健康和/或虚弱的个体。
