我们调查了10个哺乳杂交小牛（日本黑（Wagyu）×荷斯坦）和收集的数据的生理应激反应的年轻小牛长途公路运输。所有小牛均为雄性，21-47日龄。这些小牛是在牲畜市场获得的，并用商业牲畜车辆从市场运到大学。总运输距离和时间分别为306.9公里和7小时。小牛在运输过程中被剥夺了食物和水。血液样本，心电图，直肠温度收集后立即运输和一个星期后，在大学的习惯。转运后即刻，血清pH值显著降低（P < 0.01），而血清三碘甲腺原氨酸、天冬氨酸转氨酶、非酯化脂肪酸（均P < 0.05）和心率（P < 0.01）显著升高。运输后血乳酸（P = 0.08）和血清丙氨酸氨基转移酶（P = 0.06）浓度有升高趋势。这些生理反应表明，长途运输引起的应激对幼龄犊牛的肝功能产生显著影响。
We investigated 10 suckling cross-bred calves (Japanese Black (Wagyu) x Holstein) and collected data on the physiological stress responses of the young calves to long-haul road transportation. All calves were male and 21-47 days of age. The calves were obtained at a livestock market and were transported from the market to the university in a commercial livestock vehicle. The total haul distance and time were 306.9 km and 7 h, respectively. The calves were deprived of food and water during transportation. Blood samples, electrocardiograms, and rectal temperatures were collected immediately after transportation and after one week of habituation at the university. Serum pH was significantly lower (P < 0.01), while serum triiodothyronine, aspartate aminotransferase, non-esterified fatty acids (all P < 0.05), and heart rate (P < 0.01) were significantly higher immediately after transportation. The concentrations of blood lactic acid (P = 0.08) and serum alanine aminotransferase (P = 0.06) tended to be higher after transportation. These physiological responses suggest that the stress caused by long-haul transportation causes significant effects on liver function in young calves.
