VPIS update | Paul Fraser, Brendon Bell | 1.30pm
The Veterinary Professional Insurance Society (VPIS) insure approximately 80% of New Zealand’s practicing veterinarians. Each year we deal with around 100 cases, 15% of which relate to horses. VPIS sees the organisation as being more than just a commercial insurer; it has a pastoral role in looking after the wellbeing of its members. This means we try to mitigate risk, thereby reducing the number of veterinarians who have to experience litigious or disciplinary activities. As part of that process, at the annual conference, we present recent cases we have dealt with and lessons that can be learnt from these. This presentation is to give delegates this year’s update.

Sarcoid resolution rates with three different treatment protocols used in an equine hospital: a retrospective case study | Tarryn Walker | 4pm
Multiple treatment modalities have been reported for equine sarcoids, with varying success rates. Choosing the most appropriate treatment regime is difficult as sarcoids are unpredictable tumours which respond uniquely to treatment. The objective of this retrospective case study was to compare the efficacy of three different sarcoid treatment protocols used at an equine veterinary hospital in Auckland. The sarcoid treatments involved in the study were intra-lesional cisplatin injection, cisplatin bead implantation and laser diode surgery.
Management of a clostridial diarrhoea outbreak in neonatal foals on a Thoroughbred stud farm in New Zealand | Lucy Russell | 4.15pm
An outbreak of neonatal diarrhoea in 1-4 day old foals was observed on a Thoroughbred stud farm in the lower North Island, primarily attributed to Clostridium perfringens Type C. This presentation covers the basics of Clostridial enterocolitis in neonatal foals, immediate management during the outbreak, on farm prevention and planning for future seasons. Morbidity and mortality rates during the 2019 and 2020 seasons following implementation of management changes are discussed.

How to perform a palmar digital and an abaxial sesamoid nerve block | Brendon Bell | 8am
The palmar digital and abaxial sesamoid nerve blocks are valuable procedures to use for lameness diagnosis and to alleviate pain in the distal foot area. A simple, safe and repeatabe technique to perform these procedures will be discussed.
How to determine joint involvement with wounds | Brendon Bell | 8.20am
The involvement of a joint in a wound on horses legs greatly complicates both treatment and prognosis. Early recognition and treatment for joint sepsis greatly improves the outcome. Some practical tips on how to recognise joint involvement will be discussed.
How to age a horse with dentition | Katie Kindleysides | 8.40am
Where no breeding papers or branding exists, dental eruption times and incisor appearance and occlusal wear patterns remain the best way to give owners information on their horse’s age. This presentation describes the features that are most useful (and which are not!) alongside advice on managing owners’ expectations where a specific age cannot be determined. Case examples are included to highlight features typical of common age ranges and the variation that can exist.
How to take dental radiographs | Katie Kindleysides | 9am
Radiography is common in equine practice and a key diagnostic tool for dental pathology cases with digital systems being helpful to gather referral information patient-side before committing to travelling the horse for a procedure. This presentation aims to remind delegates of the most useful views, how to modify these to get good images of areas of concern, and where common pitfalls occur amongst tips and tricks to getting diagnostic images at the first visit.
How to assess for reflux | Ben sykes | 9.20am
How to perform a thoracic ultrasound with a rectal probe | Angela Hawker | 9.40am
Thoracic ultrasound is a very valuable screening tool that can add much more information onto your clinical examination. The rectal scanner is portable and accessible for an on-farm situation and is more likely to be available to ambulatory clinicians than larger machines. Understanding how to perform this in the field will enhance your diagnostic scope in a cost-effective way.
How to perform an auriculopalpebral and a supraorbital nerve block | Angela Hawker | 1.30pm
The two most commonly performed regional nerve blocks to the eye are explained. These provide anaesthesia and akinesia of the upper eyelid, which is useful for examination and treatment of eye cases, as well as minor surgical procedures.
How to diagnose a pregnancy in a miniature mare | Paul Fraser | 1.50pm
Because of the size of the miniature horse, veterinarians often are unsure as to the best method of performing a physical pregnancy test on a mini mare. This presentation describes a proven technique for performing a manual ultrasound examination per rectum.
How to perform a Caslick procedure | Paul Fraser | 2.10pm
The caslick operation is a vital tool in managing reproductive performance in mares. Because of their pelvic shape, it is especially important in thoroughbreds. The goal of an effective caslick is to create a functional valve at the level of the vulva thereby limiting the retrograde flow of air into the reproductive tract. This presentation describes a proven technique for performing this procedure.
How to remove fetal membranes: “A retained placenta in the mare, to remove or not to remove, that’s the question” | Babiche Heil | 2.30pm
Retained fetal membranes are seen in 4 – 10% of equine foalings, up to 40% in some breeds. Unlike in ruminants, this condition can lead to life threatening complications in the horse. The occurrence, pathophysiology and treatment of this condition will be discussed ensuring that every practitioner can attend mare with retained membranes and feels confident treating her.
How to perform a 1-day-old foal check | TBC | 2.50pm
A thorough examination of the 1-day-old foal allows for early recognition of abnormalities and timely initiation of treatment. We will discuss how to perform a complete clinical exam on the 1-day-old foal, the value of IgG tests and what to do if things don’t go to plan. After this presentation you’ll perform a clinical examination on the young foal with confidence and you know what to advise the owner when you find abnormalities.

Practical equine rehabilitation: a review of available modalities | Kylie Huxford | 1.30pm
The aim of practical equine rehabilitation in horses is to reduce pain, improve movement and help restore normal musculoskeletal function. It includes rehabilitating injuries to tendons, ligaments, bones, joints, muscles and nervous system. It not only focuses on injuries but also helping recovery from surgery, managing chronic conditions such as osteoarthritis, maximising performance and reducing the risk of re-injury. Appropriate treatment is often a team approach and consultation with veterinarians and physiotherapist experienced in equine rehabilitation is recommended. An accurate diagnosis and measurable assessment parameters to monitor the response to treatment are really important. Rehabilitation is an emerging field in animals and the benefits of the individual modalities is often based on human research and lacks scientific based evidence to support its benefit in horses. More research is needed in horses, especially on the appropriate treatment regimens and effects. This review will give an overview of the common modalities available to horses.
Lameness examination – when things get complicated | Alec Jorgensen | 2.30pm
Rehabilitation programmes for recovery to performance level after soft tissue limb injuries | Kylie Huxford | 4pm
An effective and safe rehabilitation programme requires a team approach between veterinarians, physiotherapists, rehabilitation centres, owners, trainers and farriers. Everyone must be on the same page for it to be successful. Confinement and controlled exercise are critical components of soft tissue rehabilitation to prevent further injury, enhance tissue healing and decrease the risk of re-injury. Other important aspects are addressing pain, proprioception, flexibility, strength and endurance to allow horses to return to their prior levels of use and competition. Programmes should be based on the different phases of tissue healing and an accurate diagnosis of injury type, location, severity and chronicity. There should be measurable assessment parameters and regular monitoring to allow them to be adapted depending on how well the tissue is healing. It is important to have clear goals, along with realistic expectations. Rehabilitation programmes are timely and can vary greatly in cost and should be adapted to individual horse and owner needs.
