Cell counts were made once and the presence or absence of Str. agalactiae, Str. uberis, Str. dysgalactiae and St. aureus were determined once in all quarter samples on seventeen normal dairy farms. Of 1,416 quarters studied, 347 (24.5%) showed a cell count of greater than 500,000/ml. and, of 354 udders examined, 202 (57.1%) showed a cell count of greater than 500,000/ml. The total number of quarters infected with pathogenic agents was 287 (20.3%), the number of infected udders being 159 (48.3%). The findings reported by the present author should also be taken into account in the recent discussion of the question whether the udders of lactating cattle intended for slaughter should be systematically condemned or, at any rate, should only be designed for human consumption after having been passed.
在17个正常奶牛场的所有季度样本中,细胞计数进行了一次,无乳链球菌、乳房链球菌、停乳链球菌和金黄色葡萄球菌的存在与否也测定了一次。在研究的1416个乳区中,347个(24.5%)的细胞计数大于500,000/ml。在检查的354个乳房中,202个(57.1%)的细胞计数大于500,000/ml。感染病原体的乳区总数为287个(20.3%),感染的乳房数量为159个(48.3%)。在最近关于是否应系统地谴责供屠宰的泌乳奶牛乳房,或者无论如何,是否只有在通过检查后才应将其用于人类消费的问题的讨论中,也应考虑到作者的研究结果。
