摘要

The objective of the present study was to determine if abnormalities in the cyclic changes of endometrial EGF concentrations can be a diagnostic tool for repeat breeder cows. First, the profile of EGF concentrations during the estrous cycle was determined using endometrial tissues obtained from 31 Holstein cows after slaughter. Cyclic cows had two peaks of EGF concentrations. Then, endometrial tissues were obtained from 12 control and 20 repeat breeder cows by biopsy on Days 3, 7, and 14 of the same estrous cycle. Endometrial EGF concentrations in biopsied samples of the controls were similar to those found in slaughterhouse materials; they were high on Days 3 and 14 (9.2 and 10.4 ng/g tissue, respectively) and low on Day 7 (3.8 ng/g tissue). Concentrations of EGF in repeat breeder cows had a different profile; they were similar on Days 3, 7, and 14 (4.4, 3.4, and 4.0 ng/g tissue, respectively). In conclusion, changes in endometrial EGF concentrations were altered in repeat breeders; these alterations may be a potential diagnostic marker for repeat breeder cows.

本研究的目的是确定子宫内膜EGF浓度循环变化的异常是否可作为重复种母牛的诊断工具。第一，屠宰后31头荷斯坦奶牛获得的子宫内膜组织测定发情周期中的EGF浓度曲线。环状牛具有EGF浓度的两个峰。然后，在同一动情周期的第3,7和14天，通过活组织检查从12只对照和20只重复种牛获得子宫内膜组织。对照的活检样品中的子宫内膜EGF浓度与在屠宰场材料中发现的类似;他们在第3天和第14天（9.2和10.4 ng / g组织，分别），在第7天（3.8ng / g组织）低。重复种母牛中EGF的浓度有不同的分布;他们在第3天，第7天和第14天（4.4,3.4和4.0ng / g组织，分别）。总之，重复种鸡的子宫内膜EGF浓度的变化是改变的;这些改变可能是重复种母牛的潜在诊断标志。
