Practical mastitis control in the field.

Research has shown the effectiveness of teat dipping and medically treating all nonlactating cows to control mastitis. However, there is a problem of getting dairy-men to accept the program. Improved educational programs might be helpful. Some means of visual evaluation is essential to acceptance. Use of indirect tests for estimating cell content can be helpful in evaluating control efforts and in demonstrating results. More intense coordinated effort by professional persons advising dairy-men is necessary.
