Mastitis in dairy cattle is the most common management disorder that causes higher economic losses by lowering production and quality of milk leads to substantial economical loss. The aim of this article was to review worldwide important advances in strategies to control mastitis for production augmentation in dairy cattle. Many scientists worked to identify effective strategies to control mastitis caused by , and others. It is necessary to identify mechanisms of infection, define clinical and subclinical states of disease, determine exposure time, and identify pathogen-specific characteristics. Evolvement of management strategies that incorporated hygienic procedures (animal, floor, and milkman), post milking standing period of animal and strategic use of antibiotic or herbal therapy at dry-off, nutritional supplementation, fly control, body condition score optimization, etc., resulted in widespread control of mastitis. The udder, teat of animal, scientific management of milking, automatic milking procedure, genetic selection are considered as important factors to control mastitis. As farm management changed, scientists were directed to redefine control of mastitis caused by opportunistic pathogens of environmental sources and have sought to explore management strategies which will maintain animal well-being in a judicial way. Although significant advances in mastitis management have been made changing herd structure, changing climatic scenario and more rigorous milk processing standards ensure that mastitis will remain important issue for future research.
奶牛乳腺炎是最常见的管理性疾病,它会通过降低牛奶产量和质量导致更高的经济损失。本文的目的是回顾全球在控制乳腺炎以提高奶牛产量方面的重要进展。许多科学家致力于确定控制由……等引起的乳腺炎的有效策略。有必要确定感染机制、定义疾病的临床和亚临床状态、确定暴露时间以及识别病原体的特定特征。结合卫生程序(动物、牛舍地面和挤奶工)、动物挤奶后站立时间以及在干奶期合理使用抗生素或草药疗法、营养补充、控制苍蝇、优化体况评分等的管理策略的演变,使得乳腺炎得到了广泛控制。动物的乳房、乳头、科学的挤奶管理、自动挤奶程序、基因选择被认为是控制乳腺炎的重要因素。随着农场管理的变化,科学家们被引导重新定义对由环境来源的机会性病原体引起的乳腺炎的控制,并寻求探索以合理方式维持动物健康的管理策略。尽管在乳腺炎管理方面已经取得了重大进展,但畜群结构的变化、气候情况的改变以及更严格的牛奶加工标准确保了乳腺炎仍将是未来研究的重要问题。
