How to Control the Increased Bulk Milk Somatic Cell Count in Dairy Cows

Abstract

Subclinical mastitis in dairy cattle covers a much larger population than cows with clinical cases. To remedy this type of mastitis, it is necessary to pay attention to the number of somatic cells in bulk milk, the history of control measures against mastitis (dry cow therapy, post-milking teat dipping, increasing the level of immunity of livestock and the herd, reducing stress, and increasing mammary health), and necessary actions are divided into two groups, fast and gradual. In the rapid group, ensuring the pre-milking striping during milking, throwing away the flake or clots containing milk, ensuring the effectiveness of the treatment of clinical cases and reducing recurrent cases from the treated ones, culling or isolating some cows from the herd (cases with very high or chronic SCC, high days in milk, reduced milk production, lack of pregnancy, history of recurrent complication, old age, etc.) are included. In the group of gradual measures, ten mastitis control and prevention measures would be implemented. It is better to use intramammary antibiotic therapy only to eradicate Streptococcus agalactiae, and treat the rest of the infected quarters at the time of drying the cow. Because BMSCC is dynamic, the efficacy of actions needs to be monitored.
