IDENTIFICATION OF HEAT PERIOD SPECIFIC PHEROMONE CARRYING COMPOUNDS IN THE URINE OF DONKEY (EQUUS AFRICANUS ASINUS)S. BALAJI, S. ASWATHI AND J. PANDIARAJAN
The donkey have been domesticated in the Sahara Desert region 6,000 years ago, perhaps earlier in Egypt, and afterwards spread to most countries of the world. In historical times, donkeys became the chief means of transport over the Asian Silk Road between China and Europe for many centuries. According to 19th livestock Census of India it was known that the total donkey population in the India has decreased by 27.22% over the previous census and the total donkeys in the country are 0.32 million numbers in 2012. Hence the present study is focused to revamp the donkey population by scientifically identifying the presence of pheromonal compounds released in urine during the heat period. During the analysis it was found that the volatile pheromone compounds such as Undecan-11-one, p-cresol and Cyclohexadecanone which was reported in earlier studies of cow and buffalo were found to be present.
