Analysis of cow sweat volatile chemical compounds in gas chromatography mass spectrometry (GC-MS) device and their importance in heat detection

Abstract

Detection of estrus is very important for the profitability of dairy cattle. Because one of the main goals of cattle breeding is for each cow to give birth to a healthy calf a year. The correct determination of the artificial insemination time to be applied to the animals by the enterprise is related to the correct determination of the animal’s estrus period. Knowing the signs of estrus that are specific to the estrus period of animals is very important in early and accurate detection of estrus. There are many methods for detecting estrus. One of the alternative methods to the methods developed to detect the estrus period in animals is the detection of volatile chemical compounds (pheromones) secreted in animal sweat only during the estrus period. This study will focus on the analysis of volatile chemical compounds in animal sweat using Gas Chromatography Mass Spectrometry (GC-MS) device and their importance in detecting estrus.
