Assessment of the Herd Management Effects on Mastitis Frequency in Austrian Dairy Farms.

Abstract

Mastitis, an inflammation of mammary tissue caused by infection, physical injury, or chemical irritation, is one of the most economically significant diseases in the global dairy industry. Both acute and chronic forms of mastitis lead to an increase in somatic cell counts (SCCs) in milk and a significantly reduced milk yield. Farmers' knowledge and awareness of mastitis play a crucial role for the preventive and therapeutic measures to manage the disease. This study aims to assess the efficacy of mastitis control practices adopted by dairy farmers in Austria by a survey-based approach. Data on milk yield and milk components were obtained from the Austrian National Milk Recording System, whereas farm management practices were documented by direct surveys conducted with dairy farmers. The study found that farm management practices related to milking, udder health, hygiene management, disease control, and nutrition significantly impact milk yield and the frequency of SCC exceeding 200,000/mL. These findings highlight the critical influence of management strategies during the dry period, nutrition, and milking practices on both milk production and mastitis indicators. Based on these results, it is strongly recommended that farmers receive training on effective strategies to improve milk yield and control mastitis.
