In addition, there are a host of other microorganisms capable of causing mastitis, either in clinical or subclinical form. Mastitis may manifest itself in various forms, depending upon many factors such as cow resistance and type of infective organisms. These three types are all treated differently. If clinical mastitis is in the herd, there will be many cases of subclinical mastitis. A herd approach, in addition to individual treatment, is imperative in the control of mastitis, as mastitis is indeed a herd problem.
Acute mastitis requires immediate treatment.
This type of mastitis is serious, and while it comprises a very small percentage of the total, death loss is common. Signs may include fever, depression, occasional lameness, swollen udder, abnormal and reduced milk secretion, and off-feed. It is imperative to obtain professional help immediately for cows with this type infection. Clinical mastitis is recognized by flakes or clots in the milk with possible quarter swelling or soreness. Clinical mastitis should be treated promptly, preferably with veterinary consultation.
