Brad Pickford

Brad has worked in the reproductive field for the past 28 years starting as an Artificial Breeding Technician before training as an Embryologist. He has created "Breed'n Betsy", an artificial training simulator and educational device for artificial breeding, pregnancy diagnosis and embryo transfer, which is now being used world wide in 33 countries.

Thanks must go to Professor Peter Chenoweth and Dr. Scott Norman, both of whom have extensive experience in Australia and the United States of America in the field of Animal Reproduction. These professionals, along with the Charles Sturt University, New South Wales, Australia, have had a large input into the development, design excellence and refinement of Breed'n Bonny through their expertise, Knowledge and trialling of the product.


I would also like to acknowledge and thank Dr Ian McLeod, Hamilton, Victoria, Australia for his knowledgeable input, and developmental assistance after many years of working in the thoroughbred racing industry, and as a small practicing veterinarian. His endless patience and continued support for this project have been invaluable.


Breed'n Bonny will be available from February 2011, with each piece being made specifically to order, with a 6-8 week delivery time from receipt of payment. Please refer to the web site for the package which best meets your requirements, or phone Brad for more specific details. Please note that the equine pregnancy diagnosis accessories are only available to registered Veterinary Universities.

Career Brief

After completing a degree in BVSc at the University of Queensland (UQ), Peter Chenoweth commenced graduate studies on bull fertility supported by the Australian Meat Research Committee. This was followed by a stint in private veterinary practice in northern Queensland before assuming the positions of Assistant Professor in the Department of Physiology and Biophysics of Colorado State University and then Associate Professor (Theriogenology) in the Department of Veterinary Large Animal Medicine and Surgery, at Texas A&M University. During this time he completed his PhD (“Studies on Aspects of the Reproductive Function of Young Beef Bulls in Central Queensland”) through UQ.


Dr Chenoweth returned to Australia in 1980 to take up the position of Director of the UQ Pastoral Veterinary Centre at Goondiwindi, Queensland, progressing to the position of Deputy Dean (Clinical) of the UQ School of Veterinary Science. He was appointed as Reader within the Department of Veterinary Medicine and Head of the Reproduction and Behaviour Section of the UQ School of Veterinary Science. During this time, he spent a year on sabbatical leave as an Adjunct Professor in the Department of Large Animal Clinical Sciences, College of Veterinary Medicine, at the University of Florida (UF).


In 1990, Dr Chenoweth returned to the US as an Associate Professor within the College of Veterinary Medicine, UF; a joint appointment with the Departments of Physiological Sciences and Animal Science. In 1997 he accepted an endowed Chair (Professor and Coleman Chair in Food Animal Production Medicine) within the College of Veterinary Medicine, Kansas State University where he was also an Adjunct Professor at the University of Nebraska, Lincoln. In Kansas he established the K-State Andrology Laboratory which provided problem-solving and QA services to the AB industries and was a co-founder of CIVAL (Consortium of Veterinary Andrology Laboratories). During this period he also helped initiate the Association for Applied Animal Andrology (


Dr Chenoweth joined the staff of Charles Sturt University’s (CSUs) new Veterinary Science program in 2005 as Professor of Veterinary Reproduction. Here he established the animal reproduction teaching programs and facilities, including the CSU Andrology Laboratory.


Research and Teaching Activities


Research Interests

Livestock male fertility/infertility, andrology, reproductive behaviour.

Current Projects

1. Role of male factors in livestock infertility and early pregnancy loss: Identification of biomarkers for male-factor infertility and potential alleviations


2. Infectious causes of livestock infertility:

Identification of the role of viral URT agents affecting sperm function; role of mycoplasmas/ureaplasmas in livestock infertility; role of gametes in transmission and biosecurity/QA.


3. Toxic effects on spermatogenesis and semen quality: Identification and evaluation of the effects of different causes of spermatoxicty, including; plant-based (eg phyto-estrogens), chemical (eg crop/pasture/animal agricultural chemicals) and antibiotics. This embraces “safety” studies for products destined for liovestock use.
