Essential resources: A globally unique bovine embryo and fetus collection
![Professor Stefan Hiendleder JS Davies Professorial Fellow](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2019-11/stefen-hiendleder.jpg?h=d011db5b&itok=hodi6pz2)
The harsh Australian environment and a changing climate require the combination of traits from both subspecies to secure national and global meat and milk production.

How does heat stress affect sheep reproduction?
![Lambs, by s_ms on PIxabay](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2021-05/sheep-s-ms-pxby.jpg?h=6eb229a4&itok=OfsyEC33)
We assessed the effects of heat stress and predicted climate change on reproductive performance of Australian sheep.

How can assisted technologies be used to improve herd reproductive potential?
![Multiple Stages embryo development](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2021-05/2-multiple-stages-embryo-development.jpg?h=c4dd2c7b&itok=dJooMWnt)
We show that variation in cow and ewe fertility influences the reproductive efficiency of herds/flocks and the success of embryo collection and transfer programs.

What started out as an interest to learn more about production beyond the farm gate quickly turned in to the foundations for an exciting career.
Beefing up your degree

How the Australian red meat industry was a drawcard for animal science student Jamie Jones.
How can we use science to help us choose better quality meat?
![MEQ Probe - Chewing the Fat](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2021-05/7-chewing-the-fat.jpg?h=a1123756&itok=VhSwyBNY)
We're facilitating machine learning to assess the juiciness, tenderness, flavour and overall consumer satisfaction of meat.

How does parental DNA affect cattle growth?
![Dr Ben Rosen & Dr Georg Liu, USDA, Dr Lloyd Low & Cynthia Liu, Davies Research Centre](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2021-05/8-cynthia-liu-photo-sex-and-parental-genome-effects.jpg?h=c4dd2c7b&itok=qz6deKVM)
Determining the patterns of expression and mechanisms of gene regulation at key fetal stages will provide us with information about normal development.

New technique delivers complete DNA sequences of chromosomes inherited from mother and father
![Professor John Williams](/davies-research-centre/sites/default/files/styles/ua_landscape/public/media/images/2019-11/enews-cattle-breeding-williams.jpg?h=707772c7&itok=6wQM8r6k)
We show it's possible to disentangle the DNA sequences of the chromosomes inherited from the mother and the father, to create true diploid genomes from a single individual.
