The objective of the study was to investigate the possibility of applying the Electronic Nose (EN) technology to analyze and detect emanated pheromonal odor changes during estrus cycle in cows. In comparison to gas chromatography (GC) headspace samples analysis and blood hormonal (estradiol and progesterone) analysis using Elisa and RIA. Also to establish a protocol to appoint the proper time of artificial insemination (AI) in cows. The study was conducted on 54 Holstein-Friesian cows. Out of sensors of the EN used in this study, sensor#2 showed the highest response to all measured perineal samples, which adhered perfectly to plasma hormone (E2) levels, and GC analysis of the perineal samples which showed progressive change in acetaldehyde as estrus was approached.
