Resumo: | Infrared thermography is a non-invasive diagnostic tool for early detection of subclinical mastitis in pastureraised dairy cows. The study was conducted on eight dairy farms, in Sena Madureira, Acre, in the Western Amazon, during the rainy season. One hundred and thirteen lactating crossbred cows were monitored, with measurements performed once a day before milking, from 02:00 to 06:00 in the morning. The California Mastitis Test (CMT) was subsequently applied. Data processing was performed in the R programming language and evaluated by linear models. Our results show that cow udder surface temperature by infrared thermography showed significant differences (p<0.05) between the months of the year. Cow udder temperatures of thermographic images were significantly different (p<0.05) from CMT results for animals with subclinical mastitis. CMT results showed that 45 cows (39.8%) in January, 52 cows (46%) in February and 57 cows (50.4%) in March had subclinical mastitis. Infrared thermography is a technique that can be used for the early detection of subclinical mastitis in dairy herds in a grazing system, as it detected an increase in the udder surface temperature of the same cows that were positive for CMT. |
