Demonstration Technique for Animal Science Extension in Causing Change of Small Dairy Milking Management

Department of Animal Science, Cornell University, Ithaca, NY 14853

ABSTRACT

Two extension methods were compared within a mastitis awareness program: 1) traditional method of writing articles and conducting county meetings, 2) demonstration technique with personal contacts at the farm. A random county survey before and after the project showed 8% more dairymen adopted the teat dip-dry cow therapy procedures in the counties where the demonstration project was. Milk company officials, fieldmen, laboratory personnel, county dairy agents, Dairy Herd Improvement supervisors cooperatively helped to contact over 750 dairies, 347 of which actively participated. Participation of dairymen was directly proportional to the number of visits the fieldman made to each dairy. Changes in milk production and cell counts for all herds were the criteria to measure the value of the program. Milk production increased for the treatment group .88 kg/cow per day compared to control herds. Treatment herds averaged the lowest bulk tank somatic cell count, 770,000 cells/ml throughout the project.
