The aim of study was to investigate the relationships among serum diamine oxidase (DAO) activity, postnatal days and the plasma copper (Cu) concentration, using calves with or without diarrhea. In healthy calves, the serum DAO activity was significantly higher at 2 postnatal days than at ≥7 postnatal days, and no significant changes were observed after 7 postnatal days. In addition, no significant correlation was found between serum DAO activity and plasma Cu concentration at all postnatal days in healthy calves. Although, the serum DAO activity in 14 diarrheic calves (66.78 ± 14.37 IU/ml) was lower than that in 19 healthy calves (170.33 ± 97.83 IU/ml, P<0.01), plasma Cu concentrations in all calves remained within the normal range.
本研究的目的是利用患腹泻或未患腹泻的犊牛，调查血清二胺氧化酶（DAO）活性、出生后天数与血浆铜（Cu）浓度之间的关系。在健康犊牛中，出生后2天的血清DAO活性显著高于出生后≥7天，且出生后7天之后未观察到显著变化。此外，在健康犊牛的所有出生后天数中，血清DAO活性与血浆铜浓度之间均未发现显著相关性。尽管14头腹泻犊牛的血清DAO活性（66.78±14.37 IU/ml）低于19头健康犊牛（170.33±97.83 IU/ml，P<0.01），但所有犊牛的血浆铜浓度均保持在正常范围内。
