Ovita funds sheep parasite research
Selective breeding is becoming an increasingly widespread tool used by stud breeders and farmers to
manage sheep parasites and produce heavier lambs.
Some of New Zealand's leading sheep breeders have been at the forefront of sheep breeding
programmes based on resistance to internal parasites, and have made considerable progress. Now
many breeders are utilising the CARLA saliva test, the latest science to battle parasites.
AgResearch scientist Richard Shaw explained CARLA is a protective antibody response produced
by sheep in the gastrointestinal tract that prevents parasite larvae from establishing. The cycle of
development is therefore interrupted, preventing parasites from developing to adults and producing
eggs to contaminate pastures.
The antibody response can be easily measured in sheep saliva.
Some sheep produce more antibodies than others, and these animals have been found to have more
protection to parasites. This natural response can be measured across the stud flock and exploited via
selective breeding, reducing the effect parasites have on sheep.
Data collected from sheep breeders over the last three years means CARLA can be incorporated in the
SIL disease (WormFEC) module so that breeders can make active selection decisions.
CARLA is correlated with improved production; an average increase of 1.9 kg live-weight in animals
was measured in sheep with high CARLA antibodies on one organic sheep farm.
"Actively selecting for CARLA will not only lead to more productive sheep, it should mean less reliance
on expensive drenches, which will encourage practice change with drenching programmes and help
to combat drench resistance."
This technology is a result of New Zealand farmer investment in Beef + Lamb New Zealand and Ovita.

Underbelly: Are dairy farmers' expectations of workers unrealistic?
I read with interest your article
Not a job for slackers and would
make the following comments.
You have highlighted my point
exactly, the hours of work
expected of dairy farm employees
They are exactly the sort of
hour s people in third world
countries accept. They are not the
sort of hours that are the norm in
Why cannot the farmers employ
more staff working fewer hours
each? If they need two employees
that each are expected to work 60
hours a week each (120 between
them) why not employ three each
working 40 hours? Every other
industry would do that, and if
they require staff to work longer
shifts they then give them more
time off to recover.
I notice that you did not
continue in the dairy industry, as
is the case with a huge number of

Your article basically says Well
I did it for six years so there is not
a problem and using imported
people to do the job is OK.
Well it s not OK. We cannot
afford as a nation to pay people an
unemployment benefit whilst
importing people to do the job
they could and should be doing.
For you to say that unemployed
are unemployed because they
don t want to work is rubbish and
you should know better. That is a
gross over simplification of the
problem. As a journalist you could
have at least taken the time to do
some research into the topic and

continue as the current situation

Staff attitude key
We agree wholeheartedly with
your positive comments,
especially where you mention that
many unemployed people are
unemployed because they don t
want to work.
We have employed two Filipino
men and they were both great
guys -- happy, hard-working,
honest, reliable, respectful etc. We
currently employ a young Kiwi
guy who is from a good family and
has similar values which makes
such a difference. Attitude is
We also enjoyed reading about
your recent tramp. I m sending it

Keep up the good work. We
enjoy your articles.

Blame the riders
We have owned and operated
quad bikes on our sheep farm
since May 1993.
Our children have grown up
using them. At one stage we had
five people riding these extremely
At no stage have we ever had to
visit an emergency department as
result of any crashes.
My husband has attended
safety lectures and was very
surprised to hear one man say he
had had 14 crashes himself!
Beggars belief really.
It is so frustrating that all
farmers are lumped together as
irresponsible, careless and slow
There is nothing wrong with a
well-maintained machine and
most of these crashes are
mistakes made by the rider, tired
or in a hurry, making bad choices.
A local farmer had a serious
crash a few years ago and he will
be the first to tell you that he
shouldn t have been trying to go
where he did. It was not the bikes
Another friend had a bike shop.
The policy there was to encourage
young riders to get a two wheeler
first -- to learn to ride! Rather
than just going straight to a four
wheeler and getting lulled into a
false sense of safety.
We do take safety seriously, and
just don t like being branded the
same as that idiot who had 14
crashes. He should not be allowed

Fatigue an issue
I am new to the farming trade
and enjoying it. I read the paper
often to find serious injury or
death involving quad bikes. A
concern I have is people s ability
and skill operating a quad on hills
or even rolling hills at times.
I think confidence pays a huge
part operating a quad.
Also fatigue would be a factor in
general in the industry.
I think drugs and alcohol is a
personal issue when involved in a
I have dirt bike experience and
that gives me the confidence to
ride a quad on hills and slopes but
I don t think more riding will
improve skill and ability.
I think through more rough
riding (in a controlled manner),
you will learn faster and build
I think farms should be graded
to assist where and when helmets
are required and not required.
Wearing a helmet at all times
becomes a hassle, especially on a
flat farm when motorcycle
accidents should be low. It should
be optional to wear a helmet

No matter what industry it is,
there is always room for
improvement within reason.
I look at it as you can minimise
death and injury but you won t
stop it. How many dairy farmers
are in New Zealand? And out of
that number what percentage
would be a target for death and
injury? If there is a target like in
business, it could drive people to
do their bit, extended training etc.
Farmers in general I think are
good with everyone having a
