FRST funding for embryo survival study

Monday, 16 August 2010

A team led by CRG scientist Dr Jenny Juengel has received funding from the Foundation for Research, Science and Technology for a research programme that aims to optimise reproductive efficiency in the pastoral sector.

The programme is a collaborative project between scientists from the Victoria University of Wellington and AgResearch’s Animal Improvement, Animal Science and Bioinformatics, Mathematics and Statistics sections with contribution from University of Otago researchers.

Poor embryo survival rates are a major limitation to livestock reproduction. Thirty-five to 45% of all ovulated eggs in sheep and cattle fail to produce offspring, costing New Zealand livestock industries at least $600 million per year.

The focus of the programme is to provide basic knowledge that can be applied to on-farm practices and ultimately meet the challenges the industry will face in the next decade, Dr Juengel says.

“We have brought together world-class research teams with relevant skills in sheep and cattle reproductive physiology to find innovative solutions for improving embryo survival. This research programme represents an integrated approach to reach the reproductive targets of the agricultural sector.”

The research looks at the key steps during the preconception and immediate post-conception periods, particularly oocyte viability, early embryo growth and maternal responses. The first major topic to address will be where and when lactation or genetics affect embryo viability.

She hopes that successful implementation of the research outcomes will improve conception rates in dairy and beef cattle and increase twinning in sheep without increasing the incidence of triplets.

The aimed 3% increase in embryo survival in the sheep, beef and dairy industries will add at least $150M annually to the New Zealand economy.
