Real-time Temperature Monitoring to Enhance Estrus Detection in Cattle Utilizing Ingestible Bio-Sensors = Method & Case Studies

다국어 초록 (Multilingual Abstract)

In the case where stock farms fail to detect estrus, a 21-day non-pregnant period arises, causing additional feed costs for fertile cows, additional artificial insemination costs, and a decrease in calf productions and milk yield. Thus, accurately detecting cattle estrus and predicting the optimum time of insemination is very important as it is directly linked to the profit and production improvement of stock farms. In this paper, we propose a real-time temperature monitoring method for effective estrus detection and also applies it to cattle for case analysis. The ingestible bio-sensor utilized in this research settles in the cattle’s rumen and measures the core temperature without any external interference, which makes it possible to collect consistent and reliable data in real-time. With the proposed method the farm owner can detect a cattle’s estrus without fail, and predict the optimum time of insemination by confirming the onset point of estrus.
