The accurate estrus detection is essential for successful reproduction. Many scientists reported the importance of pheromones for accurate detection of estrus. In addition, the choice of the appropriate device and the appropriate extraction solvent is important for obtaining quickly and more estrus-specific pheromones. In this study, sweat samples were collected in heat cows and volatile organic compounds (VOCs) in the gas chromatography mass spectrometry were evaluated using three different solvents (diethyl ether, dichloromethane, and hexane) for extraction. VOCs with different numbers and different ratios were identified in all three extraction solvents. As the solvent, 9 compounds were detected in diethyl …

For successful fertilization, a transfer system named "rapid sperm transport" generated by uterine contractions plays a crucial role. The purpose of this in vivo study was to investigate the effect of buserelin, a GnRH agonist widely used for ovulation induction after mating or artificial insemination, on bovine uterine contractility which supports rapid sperm transport at estrus. In vivo uterine contractile activity was measured by intrauterine pressure recording technique. In the study, the spontaneous uterine contractile activities of 28 cows at estrus were observed for 30 min. The cows were randomly divided into 4 treatment groups which have 7 cows each …
