Abstract

Antimicrobials are widely recommended for treatment or prevention of diseases in dairy herds. The aim of this study was to evaluate the use of antibiotics in cattle herds in Northern of Minas Gerais. Thus, a structured questionnaire addressing diseases treated, identification of mastitis, acquisition and monitor-ing of the product package leaflet and the destination of milk with residue of medication was appliedin15 properties of Icaraí de Minas (n=5), Juramento (n=5) and Montes Claros (n=5). Antibiotics were mostly applied against mastitis, and California Mastitis Test was the most used technique in Icaraí de Minas. All producers reported presence of clots in milk, which is a clinical symptom of the disease.Tamis test was used by three (60%) in Icaraí de Minas, one (20%) in Juramento and two (40%) in Montes Claros. In or-der to buy antimicrobials, interviewed people declared they consulted a veterinarian (40%), a salesclerk (40%), a neighbor (13.33%) or their own experience (6.66%). The majority of people reported to follow leaflet directions and some of them revealed to provide milk with residual antimicrobials to animals. The respondents understand the risks of milk with antibiotics to human health, although they do not know the reason. In conclusion, it is crucial training the producers concerning the rational use of antibiotics.
