摘要
生理性乳房水肿是一种奶牛非感染性代谢紊乱疾病,在荷斯坦牛中发病率较高。妊娠后期奶牛的生理结构发生了重大变化,乳腺血流量的增加、血液和淋巴循环受损以及组胺水平增加,从而导致了乳房水肿的发生。本文总结了与乳房水肿相关的致病因素,包括遗传易感性、营养管理不当、氧化应激水平高。乳房水肿会影响奶牛的产量,增加挤奶难度,提高乳房炎、乳房裂性皮炎等疾病继发感染的风险,情况恶化的话,甚至会导致奶牛过早淘汰,严重损害养殖者的经济利益。总之,乳房水肿会严重影响奶牛生产。关于奶牛乳房水肿的研究大多已经过时,需要更多的研究去更新这方面的内容。
Physiological udder edema is a non-infectious metabolic disorder,with a high incidence in Holstein cows.The physiology of dairy cows undergoes major changes in late gestation,with increased mammary blood flow,impaired blood and lymphatic circulation,and increased histamine levels,resulting in udder edema.This article summarized the pathogenic factors of udder edema,including genetic susceptibility,poor nutritional management,and high levels of oxidative stress.Udder edema affects milk production and makes milking more difficult.In addition,udder edema increases the probability of secondary diseases,such as mastitis and udder cleft dermatitis.It will even lead to early culling,which seriously cause economic damage to farmers.In conclusion,udder edema could seriously impair the performance of dairy cows.Most of the research about udder edema in dairy cows is outdated and need to be updated.
