Serum protein, immunoglobulins, complement, lysozyme, serum bactericidal activity and blast transformation of peripheral blood lymphocytes were tested in beef cattle in different herds and age groups. These parameters were evaluated in their time-kinetics, in comparison with age-matched groups of dairy cattle. Like dairy calves, beef calves up to 4 months of age were shown to have low levels of serum bactericidal activity and haemolytic complement; besides, a worse profile was detected in serum protein and gamma 2 globulin levels. Al(OH)3 and oil-adjuvanted vaccines had a favourable influence on immunoglobulin and lysozyme synthesis. An acute stressing event like transportation was shown to decrease mitogen-driven lymphocyte stimulation for at least 10 days after arrival.
对不同牛群和年龄组的肉牛进行了血清蛋白、免疫球蛋白、补体、溶菌酶、血清杀菌活性及外周血淋巴细胞增殖转化试验。与年龄匹配的奶牛组相比，对这些参数进行了时间动力学评估。与奶牛犊牛一样，4月龄以下的肉牛犊血清杀菌活性和溶血补体水平较低；此外，血清蛋白和γ2球蛋白水平的情况更差。氢氧化铝和油佐剂疫苗对免疫球蛋白和溶菌酶的合成有有利影响。结果表明，像运输这样的急性应激事件会使有丝分裂原驱动的淋巴细胞刺激在到达后至少10天内降低。
