Abstract
Chemo-signals are among the reliable non-invasive methods for estrus detection in mammals.
Water buffalo is a silent heat animal and, hence, there is search for chemo-signals
which would be effective non-invasive indicators of estrus state. We analyzed the faecal
chemical cues during the estrous cycle in buffalo and to find the estrus-specific faecal
volatile compounds adopting bull behavior assay. The faecal samples were collected at
three phases of the estrous cycle (i.e., proestrus, estrus and postestrus) and subjected to
gas chromatography–mass spectrometry analyses. We found 27 volatile compounds in the
faeces of buffaloes, of which 4-methyl phenol (4mp) and trans-verbenol (tv) were found
only in estrus faeces.
