Endometrial biopsies were taken for histological assessment from 97 cows which calved in a commercial dairy herd between April and August 1984. Sixty-two cows were biopsied at both day 26 and 40 postpartum, 23 cows at only day 26, and 12 at day 40 only. Subjective and quantitative histological criteria were assessed. Ninety-five percent of biopsies were adequate for at least subjective assessment. The distribution of criteria within each horn-day category, as well as combined readings by day and by gravid or nongravid horn were computed and significant differences noted. There was more severe inflammation and more segmented cells at day 26 than 40 postpartum, and in the gravid compared to the nongravid horn. The distribution patterns for the criteria examined provide an overview of histological characteristics in this group of postpartum cows.
1984年4月至8月间，从一个商业奶牛场中选取了97头产犊的奶牛进行子宫内膜活检，以进行组织学评估。62头奶牛在产后第26天和第40天进行了活检，23头奶牛仅在产后第26天进行了活检，12头奶牛仅在产后第40天进行了活检。对主观和定量组织学标准进行了评估。95%的活检样本足以进行至少主观评估。计算了每个子宫角-天数类别内标准的分布情况，以及按天数和妊娠或未妊娠子宫角的综合读数，并记录了显著差异。产后第26天比第40天有更严重的炎症和更多的分段细胞，且妊娠子宫角比未妊娠子宫角更严重。所检查标准的分布模式概述了这组产后奶牛的组织学特征。
