Medical Research Seminar: Manipulating reproductive seasonality

February 11 @ 12:00 pm - 1:00 pm

Medical Research Seminar: Manipulating reproductive seasonality: how a single neurohormone can improve the reproductive efficiency of Australian sheep production

Kelsey Pool

PhD Candidate, Animal Reproduction Group, University of Sydney


With projected growth in the human population over the coming decades, there is mounting pressure to find scientific solutions to feeding the world. In sheep, reproductive seasonality limits production outcomes due to annual periods of decreased fertility. As the neurohormone melatonin regulates the onset of ovine reproduction, slow-release melatonin implants are a commercial strategy to improve out of season reproductive performance in the ewe, however there is no equivalent strategy in the male. Here, we discuss strategies to upregulate ram fertility during the non-breeding season through artificial stimulation of reproductive onset.


Kelsey is a PhD candidate in the Animal Reproduction Group at the University of Sydney. Over the past few years, she has conducted studies in collaboration with the French National Institute for Agricultural Research, CSIRO, industry pharmaceutical companies and animal breeding services. Her research aims to contribute to the field of reproductive biology whilst maintaining industry relationships to produce tangible benefits to the Australian sheep industry. Kelsey’s primary interests are in understanding the role of melatonin in reproductive seasonality in sheep, and using this information to improve ram fertility outcomes and assisted reproductive technologies for more sustainable animal production.
