Any dairy herd that continually has a somatic cell count (SCC) above 400,000 cells/ml has a problem. Somatic cells are produced in response to an inflammation. Inflammation in the udder is called mastitis. If your bulk tank SCC is 750,000 or greater, you are in danger of losing your milk market in North Dakota. Since mastitis can be caused by man, machine, and environment, check all items to determine its cause. Records of cow treatments for at least two consecutive months are needed to determine if you have a few cows a with mastitis or a herd problem. Here are some troubleshooting tips to use if you’re experiencing somatic cell counts higher than you like.
Mastitis is an inflammation of the mammary gland. It is usually caused by bacteria which have penetrated the udder. These bacteria enter the udder through the teat end. They do not go from quarter to quarter without going out of the opening of one teat and into the opening of another. Proper management of cows during and between each milking is required for maximum milk production and mastitis prevention. The economic loss from mastitis makes it the dairy industry’s most important disease. The technologies to control and eradicate mastitis have been available for many years, yet bacteria still take thousands of cows out of production every year. The goal of every mastitis control program is to prevent bacteria from entering a normal and healthy mammary gland. This means that each step involved in proper milking procedures must occur at each milking every day for each cow in the herd. There are no exceptions or shortcuts to preventing mastitis.
