machine is detached. If not, the milk film will be a perfect growth medium for the mastitis-causing organisms that are on the teat, especially if these come into contact with manure and organic bedding. This will help prevent pathogens from entering the teat end and help reduce the incidence of mastitis and improve milk quality. Good teat disinfectants should have documented efficacy against the major mastitis pathogens. In addition, they should be economical and should maintain good skin condition. Both traditional and barrier teat dips are available.
OTHER CONSIDERATIONS After the milking is done, cows should exit the parlor to fresh water and feed rather than lie down (Fig. 5). This will allow the teat end to close before exposure to pathogens present in the bedding. It takes 25Â to 30Â minutes for the sphincter at the

In addition, milking routines should be optimized to avoid wasted efforts. All cows known to have mastitis or other conditions should be separated from the herd, housed in a separate pen and milked
Once a suitable milking routine has been developed, it should be typed, distributed to the milkers in their native language and posted in the milking parlor.
