DESENVOLVIMENTO DE TÉCNICA PARA DETECÇÃO DE ESTRO EM FÊMEAS BOVINAS COM DRONE

Abstract

Estrus detection is the first step towards achieving good reproductive performance on the farm. Conducting accurate detection is often a challenge for producers. Thus, there is a great search for alternatives that help in its detection. This work aimed to develop a technique to detect cattle estrus with drone. 56 females of reproductive age were used, grouped into seven groups for the test, where they were analyzed: identification of the adhesive in the cow, color of the adhesive, degree of scraping of the adhesive, influence of the flight schedule, flight height, coat color and the presence or absence of clouds when capturing the image. The data were subjected to analysis of variation and as an average to the Tukey test, at 5% significance level. For most of the characteristics analyzed, there was no statistical difference. However, the interaction of the adhesive with the flight time and coat color there was a difference (p> 0.05). For the best results observed in this study, we recommend that the flight be performed in the late morning, at a height of 20 meters or less, using orange adhesive. As a conclusion, a technique was developed that allows the use of two existing technologies, the specific adhesive and the drone, enabling the identification of bovine females in estrus.
