Profile of dairy farmers of the Joanópolis/SP region, Brazil: how they deal with Rhipicephalus microplus control and other diseases of veterinary interest

ABSTRACT:

This study made a detailed description of the milk producer of the municipality of Joanópolis/SP, situated 115 km from the largest city of Brazil, São Paulo, and how they deal with tick control and other important diseases for dairy farming. Forty milk producers were interviewed. It was found that most of them fit into family farms: small farms with family labor; 72.5% have another source of income in addition to the milk; 75% produce less than 100 liters of milk per day; and most of them are not technified (72.5% do manual milking; 55% do not keep zootechnical records; 80% do not fertilize the pastures; 87.5 % do not use artificial insemination). Tick control is made without technical criteria. A hundred percent of the interviewed applied the acaricide in the same place of milking; 90% do not use protective equipment to apply the acaricide. The prevalent cattle breed is the crossbred Girolando (87.5%), a more tick resistant breed. This may contribute to 57.5% that are satisfied with tick control. It was found that few producers (only 12.5%) have constant technical assistance. This may be the explanation for the low use of technologies and the failures observed in the diagnosis of diseases and the use of tick control.
