Speaker 1 (00:01):
Drench Wise Farm Smart with zolvis Plus from Ilanko, powered
by the Country.

Speaker 2 (00:06):
Well, greetings everyone, welcome into our third episode of Drenchwise,
Farm Smart and newer series and association with Zolwiz plus
from Alanko. My name's Rowena Duncan, Rural lead here at
the Country. It's my pleasure to once again host today's chat.
In the past two episodes with Brent Neil from Franklin
Vett's and six Generation Wided Up as Sheep and beef

(00:27):
Farmer Mark Guskett. I was also joined by industry veteran
Colin Mackay from Alanko, who was once again in studio
with me. Hello Colin, Hello Rowe. For those joining us
for the first time, Colin, just remind us of your background.

Speaker 3 (00:41):
My background is actually in parasitology and farming a very
long time ago and I've been involved in the industry
and a product development, sales, marketing registration and these days
I provide technical support for our anti parasite products with Alanko.

Speaker 2 (00:58):
Oh well, thanks so much for joining me once again.
It's pleasure and joining us on the line today we
have Gladstone Sheep and beef Farmer Michael Camick.

Speaker 4 (01:07):
Hello Michael, good afternoon.

Speaker 2 (01:09):
Now, Michael, tell me a bit about your farming operation.

Speaker 4 (01:13):
Yeah. Sure, So we're a sheep and beef farm. We're
aiding kilometers southeast of Marston and on the Gladston Hills,
eight hundred hectares. We are breed it finishing with around
four thousand breeding news and a couple of hundred angus caws.

Speaker 2 (01:33):
Now, tell me a bit about your farming journey. Have
you always wanted to be a farmer? Are you off
a family farm? How did you get into it?

Speaker 4 (01:41):
I haven't always wanted to be a sheep and bee farmer.
I came from a dairy farm, brought up on a
dairy farm out of danny Vit and worked in the
rural retail industry for a number of years, and then
just an option came up for us for my wife
and I to farm her parents' property. So we came

(02:05):
here and sort of worked away for a few years
as shepherds or stock manager, and then now we've taken
over from it, and that was thirteen years ago.

Speaker 2 (02:15):
Well, as a former dairy farmer, I can ask this question,
are you missing the early starts or is she from
BA for you.

Speaker 4 (02:22):
Very good question. Early starts always good fun. Probably would
miss the dairy check at the moment.

Speaker 2 (02:32):
Yeah, yeah, that's a good point. Actually, what sort of
season are you having?

Speaker 4 (02:36):
Sure? So our seasons better than last year. We could
still do with some more rain, but certainly on comparison
to this time last year saw moisture levels are a
lot better and feed covers are starting to sort of
build quite rapidly. So looking good, but we would like

(02:57):
more rain.

Speaker 2 (02:58):
Yeah, yeah, seems to be quite a common refrain around
the country for most of the year. Really, Hey, look
onto the job at hand. Michael, When did you first
become aware of the increasing prevalence of round worm resistance
on your farm?

Speaker 4 (03:13):
So, I guess for us or for me, it was
no real sudden light bulb moment. It's sort of been
building up for a number of years now. For us
or for me, it's widely discussed throughout or through my
farming peers, especially with discussion groups, and I guess in

(03:35):
the past, drench resistance, especially triple was pretty much almost
taboo and not really discussed with others, And probably to
be fair, it wasn't discussed because you've sort of had
the stigma of looking like a bad farmer or even
potentially devaluing your property because of dreach resistance.

Speaker 2 (03:59):
Colin, something you would have heard before as well.

Speaker 3 (04:03):
Absolutely, I think one of the key things here, Michael
is you know, being able to share experiences with your
peers is so important, and I think that's one of
the big pathways to the broader industry being able to
manage the problem of parasite resistance as people doing things

(04:23):
successfully and also people doing things unsuccessfully. So yeah, that
sharing of knowledge is very, very important.

Speaker 4 (04:31):
I definitely, and it absolutely is widely discussed now and
openly discussed, and like you said, it's an opportunity for
people to share their learnings.

Speaker 2 (04:41):
Yeah, so what did it mean for your farm? How
did it affect your farm management?

Speaker 4 (04:46):
So we're fortunate that the triple drench still has efficacy
here or acceptable efficacy, So it was very lucky. But
I guess with any product you continually you there is
going to be a chance, or the inevitable will be
that you'll end up with drench resistance. So I guess

(05:08):
for me that's always in the back of my mind
that we carry on doing what we're going to do,
and somewhere along the line, we're going to to stop
get So for me, it's just really looking at our
system and what are the risks within our system and
maybe you know, what can we do to potentially mitigate

(05:31):
or prolong those risks.

Speaker 3 (05:34):
It's really interestingly, Michael, I guess number one, the key
thing is you know your resistant status, and you know
you have a status that's worth protecting. But I'm also
really keen to hear what changes you have made to
your system of what they are to prolong the effective
life of those triples.

Speaker 4 (05:55):
Yeah. Sure, yeah. So, I mean there's a few things,
and this is evolving and it's always changing, and it's
seasoned dependent and all those sorts of things. But I
guess some of the things that we're trying to do
is it's just slow that down. So things like we've
sort of knocked out that blanket approach with regard to

(06:18):
drenching use, and we're only drenchs a certain amount, and
we're doing that even to some extent with lambs, but
with great caution. Rather than coming in after twenty eight
days regardless and slinging a drench gune around for everything,
we're sort of trying to monitor it a little bit
through people counts and just stop condition keeping an eye

(06:42):
on that potentially even whether they're on a crop or not.
We would very much like to drench trade lambs onto
the crop and then that's the only drench they get,
but again that's very much season or weather climatic conditions dependent.
The other thing we're really trying to do now is

(07:04):
have no exceptions around quarantine drenching, so we're trying to
sort of drench every new introduction onto the property, and
then in the same turn, we are exit drenching at
the end of the season. So whether whether product Zolvic's
plus seems to be a choice for an exit drench,
so we'll use a triple through the season and then

(07:25):
we'll try and have a clean out with another another
product and just things like I yes, we're not using
any single active drenches anymore. And another thing that's pretty
key to all of this is we're just running cattle
through those blocks as well to help dilate urn populations.

Speaker 2 (07:44):
Colin, I can see you frantically scribbling down some notes.
Is Michael doing a good job? Are they good notes
or are they bad notes?

Speaker 3 (07:52):
Down? They're really good notes, because you know, you often
hear the phrase there's a tool box of options, and
Michael's toolbox has been really well used. You know, we've
got targeted drench use, you've got integrated grazing of species
quarantine drenching, so you're not bringing in other people's problems

(08:12):
using crops. We are possible. You know, it's not just
one thing. Drench resistance used to be managed by rotating
your drenchers on an annual basis, and that was it,
and now it's had it's evolved to involve to using
any number of really useful tools, and I congratulate Michael

(08:33):
on his approach.

Speaker 2 (08:33):
Here, Michael, what do you think makes the difference in
protecting your drench status? What is it that you guys
are doing that you can actually pinpoint and say, yep,
that is making a huge difference for us.

Speaker 4 (08:46):
Well that's a good question. I don't know, but look,
the difference maybe for our operation is the only sheet
that we buy in size or rams. Everything else is
breed here on the farm and then obviously only goes
one way. So when those rams come in, they are

(09:07):
again I alluded to before, they're under a strict quarantine
drenching program, so they they brought in and drenched and
left off feed for twenty four hours with no exceptions.
Of course, water is available for them, and we have
hogits out grazing as well, and we send it to
a grazier those hogits where we know his status. But

(09:29):
to back that up to again, that's are no exceptions
when they are back right back on the property. We
quarantine drenching under the same process as the rams. Also,
I think I'm very lucky my predecessor here was my
father in law. He was an early adapted for triple drenching,

(09:51):
and I think that that did protect some of the
drench status. Another thing that we sort of focus on
any long acting treatment, we follow them up with a
compulsory no exceptions exit drench after that period is over with,
and just yeah, high we're going to high kettle the sheep.

Speaker 2 (10:13):
Ratio, Colin. I can see you nodding away again, Meyre
while Michael's been talking.

Speaker 3 (10:19):
Yeah, well, I can't really add anything of value there.
I think the hog it's off grazing is an interesting
one because I guess that cuts down the number of
young stock days on your farm year round, and it
reduces contamination and pressure on your drenches.

Speaker 2 (10:36):
I've got a question as a dairy farmer here, no questions,
A dumb question, as I keep telling people, so hopefully
you're not going to both laugh at me. What's an
exit drench?

Speaker 3 (10:45):
There's two types, and Michael to mention both and my
knockout and an exit drench. An exit drench is a
follow up to where a long acting product has been
used and you're just cleaning out any wombs which may
have survived or established during the payout period of that
long acting drench, whereas a knockout drench is typically regarded
as the fifth drench in a preventative drenching program.

Speaker 2 (11:09):
Right, So thanks for letting me just derail the conversation
there for a few minutes. Guys, Hey, Michael, back to you. Now,
how do you generally get your information about parasite resistance?
Where do you get that from?

Speaker 4 (11:21):
So I'm part of discussion group upon a tight discussion
group which is based in South Wapa, so Peers mainly,
and we all talk pretty openly, which is great about
just some of the situations, some of the challenges, some
of the climate challenges. It's really open and like I say,

(11:44):
that stigma from having triple resistance isn't anywhere near what
it used to be, so so we can have some
really good open, frank discussions and loom from them. Also,
reckon your commercial vet manager. They are guys that know

(12:05):
a lot more than probably what you think, and they
know a lot about the area, and they seem to
have a real good practical sense, and obviously they also
have that connection with the vets. Another one is neighbors.
I reckon neighbors, like it's really good to check with
them that they obviously farm under the same climate conditions

(12:28):
and they you know, they may do counts, so it's
good to share that information with them. So I always
find that it's really good. And then may be just
another set of eyes on your stock, on your livestock,
whether it's another colleague or a mentor, because if you
are going to push your drenching out, I think you
just have to realize that there's a risk involved in that.

(12:51):
And it could be because obviously we all want production
games that you could seriously hinder those gains by just
pushing out your dreach because you don't want dream resistance.

Speaker 2 (13:04):
Colin just on that how important is it, as Michael mentioned,
to have peers that you can have open and frank
conversations with because or the neighbors you know are going
through the same situation that you're going through.

Speaker 3 (13:18):
It's obviously vitally important. I think farmers neighbors or peers
are regarded as by other farmers. I think market research
has shown that it's the most trusted source of information.
And Michael's points very correct there about pushing out drench
I mean, in some ways drenching can get demonized because

(13:41):
the result is somewhere down the track likely to be
drench resistance. But drenching also gives us historically thirty percent
of the production on sheep farms in New Zealand, And
if you push out drenching too far, you get enormous
amounts of pasture contamination, which leads to it's greater need

(14:01):
to drench. And so it's a real balancing act to
try and work out what's the appropriate use of drenches
so you're not going to hinder productivity and you're not
going to wind up with mesopastic contamination.

Speaker 2 (14:18):
Michael, what do you think of the most important steps
New Zealand farmers can take to farm through the issue
of parasite resistance?

Speaker 4 (14:28):
Well, I think one of the best things would be
just to have a real good look at your system,
because every system is different, and then just decide from
there where are your risks and then just learning what
your drench status is or how to even find out
how you're able to find out how or what the

(14:50):
process is through finding out your drench status and then
maybe ask the question and how can I prolong that
state or the efficacy of my dreach that been I'm.

Speaker 3 (15:03):
Using sage words from an experienced farmer.

Speaker 2 (15:06):
Michael Camick and Colin McKai look, thanks so much both
of you for joining me for this episode of drench
Wise Farm Smart. It really is important, as we've mentioned
and alluded to, you know, to have those open and
frank conversations to actually explain what you're doing, why you're
doing it, what the results are, so that others can

(15:27):
maybe pick something up or learn something and build something
into their system to will farm better together. So, Michael Camick,
sheep and beef farmer based in Gladstone, thank you so
much for joining us today. Great to hear all about
your farming operation, how your season's going, and what you've
been doing in terms of round where management really appreciate it.

Speaker 4 (15:47):
Oh no, thank you, thank you for having me.

Speaker 2 (15:50):
Oh our absolute pleasure. Colin MacKaye from Alanko. Pleasure as
always to have you joined me too.

Speaker 3 (15:55):
Just one really last question. I think one of the
obvious things that Michael's doing is seekly accounting and knowing
what's going on. And as animals on the scientific you
know absolutely knowledge basis and you know there is also
a key part to it as just knowing truly what's
going on, not just relying on on ale guesswork.

Speaker 2 (16:18):
Absolutely. Look, if you want to find out more, head
