The factors mainly determining the losses caused by animal diseases, and the manner in which the economic effects are felt by the various groups of those concerned, are considered with reference to each form of disease. The losses on farm level due to those diseases among dairy cattle, which are common in most areas but vary in degree on each farm are discussed in greater detail. The losses are quantitated in part after differentiation of three components, namely prior to disposal (less efficient production and cost of veterinary treatment), on disposal (reduced slaughter value and idle production factors), and missed future income due to forced replacement. Moreover, the decision to replace animals is considered, also with reference to cows with disease. Finally, the question of which extension of veterinary knowledge is desirable to promote economic research, is discussed.
针对每种疾病形式，研究了主要决定动物疾病造成损失的因素，以及各相关群体感受到经济影响的方式。更详细地讨论了大多数地区常见的奶牛疾病给农场层面造成的损失，这些损失在每个农场的程度有所不同。在区分三个组成部分后，对部分损失进行了量化，这三个组成部分分别是处置前（生产效率降低和兽医治疗成本）、处置时（屠宰价值降低和生产要素闲置）以及因强制更换而损失的未来收入。此外，还考虑了动物更换的决策，同样涉及患病奶牛。最后，讨论了为促进经济研究需要何种程度扩展兽医知识的问题。
