Chemvet Newsletter Volume 19: Winter 2013

Dear Clients and Friends,

Well it’s happened, like the Coles Advertisement, since our last newsletter the Australian Dollar has gone Down, Down and Down.

The Pundits would all have us believe that this will bring instant relief to the Australian economy by making Australian primary products (resources & agriculture) more competitive in the world markets and the manufacturing sector will be able to get off its knees and fill the void caused by a shrinking of the once booming resources sector.

If it stays down, and everyone seems to predict a range of around 85 to 90 cents US, it will definitely continue to have a positive effect on prices for beef wool and dairy which is a great thing for all producers.

However in my opinion the pundits don’t pay enough attention to the extent that the Australian economy is leveraged to the cost of imported goods. All the major sectors of the economy are now heavily reliant on imported products. Building, mining, agriculture will all be facing quite massive cost increases once current inventory is depleted and the cost of newly imported products start to wash through the economy. Therefore the low Australian dollar is a bit of a ‘two edged sword’ for the man on the land even if we only consider the obvious items such as fuel and fertiliser

The good news is that Chemvet being a fully Australian owned company manufacturing all its products in Australia is in part immune from these escalating cost pressures. We are able to make the commitment to you that there will be no price increases for our Vetmec range of animal health products for the foreseeable future.

Kind regards,

Murray Grant

Unfortunately there could only be one winner! The winners (pictured right with their new GES3 Reader) were Anton and Bev Hutchinson, Merebene Pastoral Co, Tarcutta.

Reader software updates

Software updates are now available for both of our NLIS readers. If interested, please ring and discuss with Ron our resident NLIS reader GURU who has just spent a couple of days up in sunny Noosa completing in-service training on the reader software.

NEW Management Tags

Datamars recently bought Temple Tags, one of the largest cattle tag producers in the USA.

As stocks of the current management tags run down orders will be filled with the Temple Management Tag pictured below. These tags use the same applicators and the XL tag is slightly larger in size than our current XL tag. The plastic reacts with the laser printer better to give a more vivid and black printing result.

Why Vetmec Injectable is still the best!

Administration by injection ensures that 100% of the dose is delivered to the subcutaneous area where it readily enters the blood stream. The following data is taken from the Chemvet Study OZY9709 where Abamectin blood levels following Vetmec injection were compared to an APVMA registered commercial pouron formulation. The results speak for themselves about the effectiveness of Vetmec Antiparasitic Cattle Injection. Being abamectin is also an added bonus! Recent independent results showed Vetmec (Abamectin) injection to be 100% effective in cases where there appears to be some resistance to ivermectin developing.

We have a small stock of our 2013-2014 ‘Top pocket’ notebooks still available. Any clients wanting some, just mention them when placing your next order and we’ll send out with your products.

Addresses – keeping Australia Post happy!

Australia Post is becoming more and more pedantic with regards to postal addresses. they seem fixated on road and number being incorporated into the address, as opposed to RMB or roadside delivery etc. If you have a new address, please mention this when you place your order so we can update our database.

Murray & Diana picking the GES 3 Winner out of the box

We are all very proud of Diana who after smoking since she was 17 years of age has QUIT. She has been smoke free now for 2 months and is super confident that cigarettes are a thing of the past.

She reports that the benefits of quitting are already apparent and long daily walks with the dog along the beach are now the order of the day.

Discussion: Worms in young cattle – weaners and yearlings

Dr. Murray Grant

In Australia there are 3 main worms that commonly affect pasture grazing weaner and yearling cattle. These are:

  1. the small brown stomach worm (Ostertagia now confusingly named Teladorsagia)
  2. the black scour worm (Trichostrongylus) and
  3. the Intestinal worm (Cooperia spp.)

All are roughly equal in their importance and ability to cause illness and production loss in young cattle however Cooperia over the last few years has attracted probably more than its fair share of ‘press’ out there and appears to be the favourite topic of the drench salesperson

This is because, of the three, it is the worm that the ‘mectin type drenches (ivermectin, abamectin, moxidectin, doramectin etc) all find the most difficult to kill and control. Because it is naturally “hardy” to the Mectins it has become the predominant worm affecting young growing stock on some properties where ‘mectin’ denches have been used continually for a long period of time (about 95% of properties) therefore it is worth giving it a special mention. Resistance of Cooperia worms to the ‘Mectin style drenches is on the rise.

Cooperia worms have a few important features

1. Firstly they have a fairly rapid life cycle. Under ideal conditions (moisture and heat) they can go from egg to egg producing adults in as little as 28 days. Infective larvae picked up off the pasture can develop to adults in as little as 12 days. Therefore under ideal conditions of moisture and warmth they can build up to dangerous numbers very rapidly in a paddock grazed by weaner cattle.

2. Like Ostertagia they can undergo arrested development (in Cooperia’s case in the intestinal wall) and remain there for some time building up numbers and then emerge en masse to cause a sudden outbreak of scouring and loss of condition

3. Another very important feature of Cooperia is that cattle become immune to them at around 15 months of age. That is, although older cattle may ingest Cooperia larvae with the pasture that they are eating, these larvae are attacked by their immune system and fail to develop into adults.

In order to combat Cooperia in young cattle we recommend using Vetmec Cattle injection (Abamectin). This is because a lot higher and more certain concentrations of the active ingredient (Abamectin) is achieved guaranteeing that the parasite is exposed to the highest level of lethal ingredient (remember Cooperia is the hardest cattle worm for the ‘mectins’ to kill. Some research results show Abamectin appears to be more potent against Cooperia than Ivermectin. This may be important when deciding which drench to use.

Where young cattle such as backgrounding weaners or young fattening cattle are run in high rainfall country at high stocking rates a tighter than normal re-drenching interval is often necessary. For instance in South Gippsland, or eastern slopes of the Otways in Victoria and north west Tasmania drenching at 6 week intervals from Feb through to June may be necessary. From then on the cattle will become immune & don’t require this drench frequency.

We also recommend using non- drenching management techniques to accompany and enhance the effectiveness of your drenching program

These can include:

• Avoid using the same paddocks or rotation of paddocks to wean into year in year out. This can result in a build-up of Cooperia in these paddocks just waiting to infect your weaners. If this is unavoidable then graze these paddocks out with dry adult cattle after the weaners leave. Sheep of course would even be better.

• On drenching move weaners into paddocks grazed by adult cattle

• Also the older fashion drench Levamisole, whilst it can struggle against the other important worms, it is highly effective against Cooperia. Therefore on properties combining a levamisole pouron with the Abamectin Injection can be really effective (more about this in future newsletters).
