The Animal Welfare Scientists of the future were in the spotlight as they presented their research at an international conference held at Writtle College.

The topics covered were wide-ranging: from the sexing of chickens before they hatch, to the effect visitors have on the behaviour of macaques in zoos; from the nocturnal behaviour of orphan young Asian elephants in a Sri Lankan rehabilitation centre, to empathy in rats.

A total of 15 students - 14 of whom won this year’s Animal Welfare Student Scholarships from the Universities Federation for Animal Welfare (UFAW) – presented their studies at the organisation’s annual meeting.

They had travelled from universities and colleges from across the UK, as well as those in Austria, Portugal and the USA, to share their projects.

Among them was Harry Appleby, BSc (Hons) Animal Science student at Writtle College, who presented his research which evaluated oestrone sulphate as a pre-hatch indicator of sex in ISA brown poultry.

The molecule oestrone sulphate can be used as an indicator of sex in poultry before the chicks have hatched. The implications of the research, overseen by Writtle’s Dr Angela Murphy-Thomas, could be far-reaching – currently 4.2 billion male chicks of a laying breed are slaughtered at day old annually, due to being a surplus by-product of the laying industry.

Harry, 21, from Tendring, said: “Identification of sex in ovo, prior to the development of pain perception at day 10.5 of incubation could be considered an ethical alternative to slaughter after hatch. Our study highlights the significance of oestrone sulphate as a suitable marker for identifying the sex of chickens before hatch occurs. In turn, it could be suggested that, with adaption and development, this method may be a suitable alternative to the slaughter of male chicks at day old.”
