A rare case of agalactia in a 7 year old cow is described. At the start of the 5th lactation all the teat cisterns were obliterated. Post mortem x-ray examination, with bariumsulfate contrast deposition in the glandular--and the teat cisterns, showed horizontal membranes in the proximal half of the teat cisterns. The membranes were 13--20 mm thick and consisted of fibrous tissue. Glandular tissue, distal parts of teat cisterns and teat canals were normal, and there was no sign of mastitis Obliteration of the teat cisterns, which had developed during the dry period, between the 4th and 5th lactation periods, were assumed to be a result of improper machine milking. The importance of overmilking is discussed.
描述了一例7岁奶牛无乳的罕见病例。在第5次泌乳开始时，所有乳头乳池均闭塞。死后X线检查，硫酸钡造影剂沉积于腺泡和乳头乳池内，显示乳头乳池近端一半有水平隔膜。隔膜厚13 - 20毫米，由纤维组织构成。腺组织、乳头乳池远端部分和乳头管正常，无乳腺炎迹象。乳头乳池闭塞发生在第4和第5泌乳期之间的干奶期，推测是不当机器挤奶所致。讨论了过度挤奶的影响。
