—Lancaster Farming. Saturday, August 6, 1977 16 Mastitis and dry cow treatment Mastitis management and control has been a long sought after goal in the dairy industry. Unfortunately it has also been an elusive goal. With all of the work and studies and 'research being done on the problems of mastitis, the incidence of mastitis has not decreased markedly over the past SOyears. Approximately 50 per cent of the cows in car dairy herds are still infected. In many herds the extent of mastitis control is simply the infusion of a- prepared treatment 'into- a quarter whenever there is a flareup. ‘ But the most rewarding results in mastitis control and management can be ob tained from a properly conducted ,dry cow program. Today, treat or not to dry treat; that has been the much argued question ever since dry treatment was first in troduced. There is little argument that at least problem cows should be dry treated. But highly qualified and knowledgeable people will still argue both sides as to whether all cows should- be dry treated. Let’s examine both sides. Why dry treat only problem cows? In tills cast problem cows can be divided into two categories. One way is to treat only those cows which have had actual cases of mastitis during the lactation.

The expense of the product is one reason but is not a valid, argument considering the consequences. “Why bother to treat an animal which does not have a problem? is another comeback. More serious and not yet resolved problems is the possibility that continued and ' constant use of a dry treatment product in- every cow will result in development of resistant strains of bacteria which will then not respond to regular treatment. This is always a possibility but has never proven td be of suf ficient significance to be of concern. ■ " ■ - . Another more serious drawback had been the evidence that dry cow treatment which eliminated' the more common, routine,- easily - treated organisms from the udder, made it more susceptible to the more serious acute coliform mastitis. In some herds it did appear that as 100 per cent dry treatment was'practiced and routine cases of mastitis subsided, that there was an increase in acute, coliform mastitis. However, this increase appears to be related to environment and management also.

So a complete dry cow treatment program will have to be coupled with improved environment management to prevent contact of the udder with an overwhelming infection.
