We offer both manual and ultrasound pregnancy diagnosis for cattle as well as structural assessment, service ability testing, and semen analysis for your bulls.
Manual/Ultrasound & foetal sexing
Pregnancy diagnosis is an essential element of running a productive, economically viable beef herd. Through the use of pregnancy testing, you will be able to ensure a tight calving interval as well as being able to cull unproductive empty females at an opportune time.
At HVC, our vets pride themselves on providing a highly accurate and professional pregnancy testing service. We offer both manual and ultrasound pregnancy diagnosis. The method of pregnancy testing used will be determined by the joining interval and your concurrent on-farm requirements. Knowing the pregnancy status of an animal shortly after joining allows economic decisions to be made allowing higher productivity within your enterprise.
Our vets have the ability to accurately age pregnancies in a 30-100 day window of foetal age. This allows producers to accurately identify AI or ET pregnancies, as well as record expected time of calving to facilitate drafting into calving groups. Batch calving based on the cycle of the joining period that a female has conceived enables significantly improved labour efficiency at the time of calving, as well as more specific management of the pregnant cow. Commercially, foetal ageing of maiden heifer groups enables the selection of shorter calving periods and the early marketing of surplus PTIC females, which significantly increases the profitability of these cows through their first calving.
Our vets also have the ability to accurately determine the sex of the foetus as required.

Structural Assessment, Service Ability Testing, Semen Analysis
In order to drive the genetics and fertility of an enterprise, investment in sound quality bulls is essential. Having already selected bulls, an annual Veterinary Bull Breeding Soundness Evaluation (VBBSE) is critical for minimising the risk of bull related issues during joining. A VBBSE involves four key components:
There are many reasons why bulls fail during joining, particularly as we drive more profitable systems with shorter joining periods. It is essential to examine bulls to ensure that they are fertile before commencing the joining period and to observe bulls regularly throughout the joining to detect and manage any breakdowns that occur.
Monitoring the bulls for structural soundness can limit the risk of breakdown. The assessment of semen quality and quantity is essential in a range of joining scenarios, particularly when single sire mating, this involves crush side semen assessment, in conjunction with sperm morphology testing.
Service ability testing is the only test available to confirm that a bull can do the job he was purchased to do and is therefore an essential component of examining a working bull. Assessment of penile anatomy and erectile function can also be performed at this time. It is recommended that all mature bulls must undergo this test annually as conditions acquired throughout their working life can limit their serving ability.
At the stud level, pre-sale bull examinations allow seedstock producers to sell a quality assured product to their commercial producer clients, which will help reduce bull-related joining failures. These pre-sale examinations will also facilitate the insurance of newly purchased bulls.

Pestivirus, also known as Bovine Viral Diarrhoea Virus or BVDV, is a major disease that affects cattle across Australia. Depending on the strain of virus and time of infection, Pestivirus has the potential to affect female fertility and calving rates, while also potentially causing respiratory disease and ill thrift in young animals.
HVC offers comprehensive Pestivirus management support. Monitoring levels of herd immunity to Pestivirus, particularly in the maiden heifers will aid in minimising the risk of Pestivirus. This plan generally involves collecting a farm management history and a combination of blood testing and/or ear-notching. As part of HVC’s consultancy services, strategic disease management covers diseases such as Pestivirus allowing for easier management that is timed in with other husbandry events, thus increasing efficiency and reducing double handling of animals.

Johne’s Disease is a chronic wasting disease that can affect cattle, sheep, goats and deer.
It is an infection caused by the bacterium, Mycobacterium paratuberculosis, which resides mainly in animal intestines, but can survive in the outside environment for several months. A Johne’s affected animal will struggle to absorb nutrients from grazing, leading to chronic scouring, wasting and eventually death through starvation. The disease is spread from carrier animals to young animals (under 12 months) through the circulation of contaminated faeces in water sources. JD infected cattle may excrete the disease prior to developing clinical symptoms themselves.
The introduction of Johne’s disease into a herd can impact the profitability of an enterprise and this disease has important trade implications both nationally and internationally. Prevention relies on sound biosecurity practices and is something HVC can assist to implement. As part of strategic disease management, HVC can construct a personalised farm biosecurity plan to ensure the correct steps are being implemented to achieve Johne’s disease prevention.
Recently, the Johne’s Beef Assurance Score (J-BAS) has been developed as a risk profiling tool for beef producers. This scheme utilises self-assessment which allows producers to demonstrate what they are doing to minimise the risk of Johne’s Disease on their property. The J-BAS score is then able to be used as quality assurance by producers when buying or selling stock. HVC can assess your property and assist in your Johne’s Accreditation and J-BAS requirements.
HVC has AQIS accredited vets that are able to assist with the required checks and certification involved with exporting animals overseas.
Australia has an excellent reputation for agricultural exports thanks to the efficient regulation of all standards. Many protocols need to be strictly followed in order to satisfy requirements of trade partners, so trusting in the Australian government accredited veterinarians (AAV) at HVC is a worthwhile investment.
