Embryo Transfer and IVF: Insights from Dr. Rory Nevard, University of Sydney
In this episode, Dr. Rory Nevard from the University of Sydney shares his expertise on cattle reproduction, comparing Multiple Ovulation Embryo Transfer (MOET) and In Vitro Fertilisation (IVF). We explore differences in adoption and outcomes betweenAustralia and the United States, expected results from fresh and frozen embryos, and current research into IVF protocols. Rory also discusses the pros and cons of using FSH, future innovations in reproductive technologies, and practical advice for breeders considering ET or IVF for the first time.

Stimulated In Vitro Fertilisation (IVF) in Cattle: Why Follicle Stimulating Hormone (FSH) Matters
In this episode of Making Better Bovine Babies, Dr. Don Strazzeri, Technical Services Veterinarian at Vetoquinol, breaks down the fundamentals of bovine IVF (also known as IVP) and how it compares to conventional embryo transfer methods.The spotlight is on stimulated IVF—specifically, how using FSH can improve embryo quality, success rates, and cost-effectiveness in modern breeding programs. Whether you're an experienced breeder or new to assisted reproductive technologies, this episode offers a clear, practical guide to optimizing your IVF protocols.Topics covered include:What bovine IVF (IVP) involves and how it compares to conventional embryo transfer (MOET)Step-by-step explanation of the IVF/IVP process, from oocyte collection to embryo transfer or cryopreservationDifferences between IVF (in vitro fertilisation) and IVP (in vitro production of embryos)Benefits of IVP for genetic progressWhy IVP is growing globally and how adoption varies across countriesThe role of FSH in stimulated IVP protocolsEvidence supporting improved embryo quality and survival rates with FSH useCost-benefit considerations when including FSH in IVF programsPractical guidance on when and how to use FSH effectively

IVP (IVF) - what we can learn from the US with Dr Ky Pohler
Texas A&M Associate Professor Dr Ky Pohler, one of Amercia's leading bovine reproductive physiologists, shares his extensive knowledge about In Vitro Fertilisation (IVF) in the US market with Vetoquinol Australia's Rebecca Arnott.
Topics covered include
why 80% of US embryos are produced from IVP (IVF) compared to Australia's 5% or so
whether Australia is likely to follow suit
results (MOET vs IVF, fresh vs frozen embryos)
cost/embryo and cost/pregnancy
differences between and within breeds
why brahmans shouldn't be treated in the same way as Brazil's bos indicus cattle (Nelore)
why Wagyus dont respond as well to IVP and further work needed
technicians and logistical challenges
optimising outcomes
the benefits of stimulated IVP programs with follicle stimulating hormone (FSH)
the importance of media
pregnancy losses; and
the next ten years

Learn more about MOET & IVF with Dr Udo Mahne and Rob Costello
Cattle ET veterinarian Dr Udo Mahne and Walcha Angus seedstock producer Rob Costello of Nairn Park Angus share decades of knowledge and practical experience relating to embryo transfer programs.
For those contemplating MOET or IVF/IVP, these interviews with Vetoquinol's Rebecca Arnott provide valuable tips and insights including:
typical results (and variations seen)
pregnancy rates (fresh and frozen)
getting an extra 30 calves from 5 donor cows
donor and recipient management
the importance of nutrition including minerals
management practices to help maximise the number of calves produced from a single donor cow
significantly lower cost/pregnancy of MOET vs non-stimulated IVF
why MOET is likely to remain the most viable form of embryo transfer for most producers
a common MOET protocol; and
benefits of FSH in MOET and IVF/IVP

Assisted Breeding and Future Trends with Dr Shane Thomson (HVC)
In this episode, Rebecca Arnott catches up with Dr Shane Thomson of Holbrook Vet Centre to learn about the different forms of assisted breeding available, how these are continuing to evolve and how to decide which is best suited to your situation.
Some of the advantages and disadvantages of natural mating (NM), Artificial Insemination (AI and FTAI), Embryo Transfer (ET & MOET) and In Vitro Fertilisation (IVF) are discussed as well as some key differences between breeds and geographic areas.
Shane also shares his thoughts on what the future looks like, particularly given the rapid advances with genomics and embryo transfer as well as some of the key challenges facing the industry.
Making BETTER Bovine Babies is a podcast aimed at educating, inspiring and at times entertaining anyone who is passionate about breeding better cattle (and more of them).
Produced by Vetoquinol’s Repro360 team, we share some of the stories, knowledge and expertise from cattle vets, AI Technicians and producers around the country as well as some fundamenals from our own team as we delve into the fascinating world of ‘making better bovine babies’.
