Resumo

The aim of this study was to evaluate the diagnosis of estrous in Canindé goats used infrared thermographic images. The Canindé goats used in experiment, belong to Production Center of Small Ruminants. The goats were subjected to estrus induction and monitored with regard to their behavior and blood levels of hormones. Temperature measurements were continuous during estrous signs and even disappearance of behavioral characteristics. Were evaluated different areas in females: vulva, perivulvar, dorse and venter regions, delimited by a quadrant that allowed the specification of assessed region. In addition to specific behavior of estrus in ruminants were observed in vulvar region perivulvar signals swelling and redness and parallel identified the temperature rise of region by thermographic images. Were observed in vulvar region perivulvar signals swelling and redness and parallel identified the temperature rise of that region by thermographic images in goats in estrus. There was a significant effect for all temperatures of the regions evaluated for the thermographic images and infrared thermometer, except for the temperature of the vulvar region. The temperatures measured using the thermographic camera submitted a difference in the data set, allowing measurements observed higher temperatures compared with the temperatures measured with an infrared thermometer. So, due the precision and speed of the method the thermographic images used for detecting estrus is applicable and important. In animal production, thermography has seen used in detection of metabolic disorders, diseases and infections. In addiction, is usedin understanding thermoregulation due to chenges in temperature and the impact of environmental conditions.(AU)
