A welcome new face at OVH in the past month has been Richard Sanders. Richard, an experienced mixed practice vet from Victoria, has been helping us while Kim Rolls has medical leave.

Many of you have met Richard either at OVH or in the field as he has been covering many kms preg testing cattle for our clients. Richard is heading north to Qld and NT for dry season preg testing once cyclone Marcia abates.

Richard's professionalism, skill and easy manner have been greatly appreciated by our clients, patients and staff.

Thank you Richard from us all!

01 Regulations for supply of prescription drugs for animals

Supply of restricted substances

In recent times Orange Veterinary Hospital has been under increasing pressure from producers and clients to supply restricted substances (e.g. antibiotics, pain relief etc) without one of our veterinarians having physically examined the animal that the substances are required for. 

Our vet Genevieve explains the regulations that we are required to adhere to regarding supply of prescription drugs for animals.

Drug supply has always been regulated by legislation however this is now being more closely monitored and enforced by the Veterinary Practioners Board and Government regulations. To comply with these regulations we would like to remind clients of our legal obligation in regards to the dispensing of restricted substances and medication.

It is a government requirement that prior to a veterinarian dispensing medication for production or herd animals (cattle, sheep, goats, alpaca, poultry etc) that they:

  1. have spoken directly with the producer/client, AND either

  2. have seen at least ONE of the affected animals, or

  3. have attended your property within the last twelve months, in order for the veterinarian to be familiar with the health status of the animals under ‘his/her direct care’.

In the case of companion animals (dogs, cats, horses etc) we are legally required to have examined the individual animal before any medications can be dispensed.

We would like to thank our clients in advance for their understanding of our legal obligations regarding the dispensing of restricted substances.  

02 Worms, worms, worms
SetWidth600-worms-in-sheep

Internal parasites are the largest animal health cost to the Australian sheep industry, closely followed by flystrike, lice and post weaning mortality (more of that in subsequent newsletters). Losses in production will continue to rise as sheep worms become more resistant to commonly used chemicals. There have been no solutions to the problem of anthelmintic resistance and the problem is getting worse. We have to look beyond chemical control and develop strategies for optimising worm control. 

Key strategies available for control include anthelmintics, genetic selection for host resistance, grazing management and the improvement of host nutrition. Hopefully other strategies will become available soon e.g. vaccination.

Modern worm treatments are (resistance aside) highly effective, easy to use and relatively cheap. However, this is not without a cost. Get your head around this: as a rule, the better the control through drenching, the greater the selection for resistance in worms for the drench group used! Worms are the problem, not the anthelmintic!

In light of this, we need to:

  • Perform regular worm testing before strategic drenching (eg. pre-lambing, first summer, second summer, weaning)
  • Drench correctly: the right drench at the right time at the right dose
  • Include a larval culture at least once a year to get an idea of the populations present
  • Perform post-drench checks including larval culture for each annual drench rotation
  • Create safer pastures for susceptible sheep (lambing ewes and young sheep) by rotational grazing
  • Provide good nutrition for young sheep and pregnant ewes to ensure target weights at weaning are met
  • Breed resistant sheep
  • Get expert advice!
03 How to purchase a horse wisely
SetWidth600-pre-purchase-exam

Given that they don’t come with a warranty, you need to gather every bit of useful information about a horse before you hand over your hard earned cash! A pre-purchase examination of a horse can give you vital information that you need to know before making the purchase. Pre-purchase examinations should be a standard procedure you undertake before buying a horse.

The procedure must be carried out by a qualified vet and usually consists of: a thorough physical examination, dental assessment including aging, and lameness assessment. Sometimes additional testing is performed as a result of initial findings or at the buyer’s request (e.g. joint radiographs).

The job of the vet looking at the horse is to make sure the horse is fit for its intended use. A horse you want to compete with has different needs to a horse you intend breeding from. Some diseases which are manageable may be acceptable to you if you are paying $1000 for a horse but not if you are paying $20 000 for a horse. Thus, the job of the vet is to not give a pass or fail to a horse, but rather to gather information so that you can make an educated decision before your purchase.

If you are planning on buying a horse, consider a pre-purchase examination first.

04 Cattle crush design and safety
SetWidth600-cattle-crush

A well designed crush makes for efficient, low stress and safe cattle handling. As vets, we have seen the full spectrum: from hydraulically operated walk-through crushes to the older style guillotine crush. From our perspective we are looking for a crush which is efficient to work in and safe. The cattle crush can be a dangerous place – injuries from crushing, being kicked, or being knocked by fast moving bits of the crush are well documented.

Choosing a crush will depend on a number of factors including stock to be restrained, the procedures to be performed, staffing levels and experience, and cost. There will not be one crush which suits every purpose. 

To help vets, farmers and manufacturers with design and selection of appropriate crushes, the Australian Cattle Veterinarians put together a document which is now sitting on their new website.
