An electronic drench gun, believed to be a world-first,
has the potential to save farmers ''thousands of dollars'', the
Oamaru-based company that designed it believes.
Te Pari Products Ltd, which manufactures livestock handling
equipment and animal husbandry products, won the Grassroots
Innovation Award at the recent Fieldays at Mystery Creek.
The gun integrated with an electronic weigh scale which
calculated how much drench an animal needed.
That data was transmitted via Wi-Fi to the gun, which
delivered a calibrated dose based on the animal's exact
The gun eliminated both under-drenching and costly
over-drenching that could occur when groups of stock were
drenched to the animal with the heaviest weight, Te Pari
director Jeremy Blampied said.
''The gun will also work against drench resistance and
significantly improve drench effectiveness.
''We believe savings of up to $1 per cattle beast per drench
are possible, depending on the age and cost of the drench.
''It will offer some real economic benefits and is
environmentally friendly, as farmers are not needlessly
wasting drench,'' Mr Blampied said.
A statistics button on the gun showed the total drench used
and the number of doses administered.
It could be linked to EID on the weigh scales to record dose
amounts and frequency for individual animals.
The Te Pari team had been working intensively on the gun for
about a year, although it had been ''on the drawing board''
It was hoped to have it in production by early next year. It
was suitable for sheep and cattle and it was expected to
handle both pour-on and oral drenching.
Locus Research managing director Timothy Allan, who was among
the judges for the Grassroots Innovation Award, said the gun
was a ''great idea''.
''It may look like a simple product but achieving it would
have been extremely difficult. There's a good reason why this
hasn't been done before,'' he said.
Te Pari Products was established in the North Island in 1979
by Pete French, whose father, Ted, developed a scissor-action
docking iron, which his son redesigned and refined.
Coincidentally, that docking iron won a Fieldays invention
award in 1980 and an equipment award in 1981.
The company had been awarded six other New Zealand Fieldays
accolades and one Australian national fieldays award over the
next 10 years.
The Blampied family purchased the business in 1997 and
relocated to Oamaru in 2002-03.
It now intends relocating its Humber St manufacturing
operation to the town's new North End Business Park.
