Hi everyone, I'm Nikia Nolan, Livestock Officer for the North Coast Local Land Services. Today I'd like to go through with you a little bit of a herd health check, which you should be doing routinely as you check your cattle and your water and grass each day.
So behind me here we have a few steers.
It's always good to be familiar with what cattle you are
working with each day, that way, when something
unusual pops up, you're much quicker to detect it.
In this paddock we have approximately 100 steers.
We started off with 127, but when we weighed them the
other day, we removed the bottom 25% to 30% so that they
weren't getting bullied
and they can focus on growing.
These steers average about 400 kilos or just over, with the
main range being between 360 to 430 kilos.
It's always good to be familiar with what production your
cattle are doing, that way you're quicker to identify if
any are slipping or going backwards.
Generally, when I first come into a paddock, I do a quick
scan to make sure all the cattle look like they belong in
the same mob, they have the same visual ID tag, and also
they all have their own NLIS tag.
It is important that all your livestock have an NLIS tag,
as this is part of the National Livestock
Identification System.
You should also check that there's no unusual stock which
may belong to neighbours or be wandering stock.
As a part of a general health check, I'd like to
identify a few key things that you should be checking off as
you look at your cattle routinely, you should be
looking for if there's any flies or ticks or other type of
parasite annoying them.
This might be shown in head flicking, tail swishing,
cattle appearing irritated or just the visual, seeing plenty
of flies attacking the cattle.
They may also get weepy eyes, have drooling noses, or have a
lot of wet manure and bulk piling up at their tails.
You should also be checking for other health issues such as
noisy breathing, drooling, coughing,
general lethargy, so tiredness,
weakness, sulking, so, even though these
cattle have all come up to me in this paddock, it is always
important to go for a look further out to see if there's
any cattle isolated by themselves, sulking or
unable to move.
If your animals are bellowing, appearing very alert
and reactive, or chasing your pet dogs or working dogs,
there may be an issue of pests such as wild dogs or even town
dogs coming and irritating your livestock.
When you're moving your livestock, whether walking
them through a gate, or just pushing them along
up a laneway, it's also important to take note if any
have physical injury, are lame or maybe lethargic as far
as falling behind, slow walkers or starting to drool as
they're walking along.
In grazing systems, when you can't tell the cattle exactly
what to eat, as they are selective grazers, that means
that you need to be aware of nutritional related illness.
You should be looking for pot bellies, drooling,
non-eaters – so they may be falling away or show
a wasting disease,
so becoming thinner, just an overall appearance of a general
sickness or loss in body condition, or they may
become downer cows, meaning that they come down and
cannot get up.
Nutritional risks related to some of the characteristics in
a grazing system include, nutritional deficiencies,
which may derive from a deficiency in soils such
as cobalt, common in coastal areas, or selenium,
or it may even be related to the pasture species, such as
clovers and legumes, which generally are related to
issues such as bloat.
After periods of drought or rainfall events,
where there's a fresh green pick or rapidly growing grass,
there can also be other issues such as grass tetany related to
a magnesium deficiency, or other issues where the grass
is growing rapidly, such as nitrate poisoning.
When you go to move your cattle, it's always good
to have a herd head count, that way you know exactly how
many you've moved and keep record of mortality, sickness,
and changes in herd numbers.
If your herd number changes, it's always best to go for a
drive around and make sure you find where those numbers
have gone missing.
These may be mortalities, illness – so they may be
sulking over in a corner, which need treatment or moving
into a hospital pen,
or they may be stock that have gone missing where you need to
go find them.
Stools can say a lot about cattle health.
Looking at this pasture, it's good quality, but from
where we are at in the season, it's all starting to
get more fibrous, go to seed head and be reproductive.
Therefore, you should be expecting the stools to get a
bit more structure about themselves just like this,
as there's a lot more fibre in the diet than if they were
grazing this grass when it was still mostly
vegetative and soft.
Let's go take a look around and see what other stools
we can find.
This stool here is starting to get a little less structure and
a bit more watery.
The cow that produced this may be choosing to pick around and
get a lot more leafy matter, rather than the
reproductive seed head.
This stool here, is a bit more runny than the last two that
we've looked at.
The colour of it is dark green, which is expected
on pasture like this, which is high in chloroplasts.
If it was any darker or an unusual light colour
like white, cream or even bloody, then you will be
concerned about the health of your animals and you should
look further into what's causing the scours.
If this stool was runnier, or had bubbles, that's a good
tell-tale sign of acidosis, which may have been caused from
a diet change or something upsetting the rumen, such as
being off-feed and having a quick feed, or having too good
a quality of feed and not enough fibre.
If there's other signs of poorly digested material in
your stools, such as grain heads, then you should
also be looking into the digestibility and fibre content
of your feed.
We'll go for a walk around and just see if there's any cattle
that I would want to identify as ones that I'd want to keep a
closer eye on than the others over the next few days.
This guy here, you can say compared to the others, he's a
bit more of a rougher coat and I would be a bit worried,
but considering the season we're at, we're coming out of
winter into summer, he is most likely just losing
his winter coat.
He still has good body condition, his neck's
shiny where most of the roughness has came from and his
bum is clean.
If he was sunken in, had a dirty backside then I would be
considering other parasites or something else, causing him to
become that bit more of a woody, poorer conditioned,
rough coat.
We'll go for a look around further.
So these guys should all be gaining weight.
So you don't want any bullying, and as you
can see here, there's a few smaller guys in the mob.
They're also fellas that you should be keeping an eye on,
making sure they're not getting bullied or isolated from the
rest of the cattle.
As you move through you should also be looking for
lameness or injury.
A lot of them that are at the front of the mob are generally
the more confident, bigger, healthier cows.
As soon as the cow starts feeling a little bit off,
or isn't as confident as the others, it will be hiding a
bit more behind the mob or off to the side, so it's always
good to have a good thorough check through and make sure
that they're all okay.
This little guy here, he's smaller, got a bit of a
rough coat, so he's definitely the type of steer I'd be
keeping in mind, as I do my routinely checks each day.
If you're checking your cattle and they don't stand up,
it's always best to make them a bit uneasy and stand them up
just in case, even though you think they're just quiet,
they may have a bit of downer cow or have an injury such
as lameness, where they're just wanting to choose rest
over walking about.
This one here is slightly lame, so it's best to
remove him from the mob and treat him up at the yards.
He is a bit smaller than the others, so this could have
been a result of bullying, where he slipped over, also,
we have had plenty of afternoon storms with rain, so the ground
is quite slippery, so he may have just slipped over or it
could be something else, such as an object stuck between
his toes or an infection within his foot.
So we'll pull him out, take him to the yards, check him out,
diagnose it and treat it for what it is.
You can see this guy,
he's got a few warts on his neck.
Warts a generally a sign of stress.
We have just came out of some pretty dry conditions,
which means that warts can be typical on a lot of cattle.
Even though it doesn't look very appealing, they aren't
that much of a health issue.
Overall, I'm really happy with this mob.
We will remove that one that's lame and treat him, but the
rest are all pretty happy chewing their cud, ready to
move on to the next paddock.
Now that we've covered most of the herd health check
looking at weaners, like these steers, let's move
over to a cow and calf mob where there's a few more things you
should be looking out for.
We're just here with a cow and calf herd, they're a bit
noisy because we just moved them into this holding yard
with some dogs.
If you get into your paddock where they should be relaxed
and they're bellowing like this, it's a good tell-tale
sign that something's really irritated them, such as wild
dogs or town dogs.
When you're looking at these girls, you can see that
they're quite happy, their ears are up, there's no drooling,
there's no tonguing, they're not hollowed out
or woody looking, their bums are pretty clean,
and there's no big tell-tale signs of fly worry, ticks,
or any type of pneumonia or some type of disease.
When you're running bulls, it's really important to not
have them too thin or too fat.
These two boys here are a pretty good example of how they
should be looking, because if they get too fat or too thin,
they start losing libido.
That means they stop working and chasing your girls,
trying to get them pregnant again for next year.
I've just taken notice of this bull.
As you can see, his penis is a bit droopy looking and it's
a bit pink,
but after I followed him around for a bit, he sucked
it back up, therefore, he must be just active and
chasing his girls.
If he wasn't sucking this back up and it kept
dragging around, or appeared a bit swollen or a bit more pink
or discoloured, then you would be worried he's had some
type of injury.
For that I would recommend getting a vet out.
When you're looking at bulls, it's really important to take
note of their conformation.
They should have good sound feet, healthy eyes,
not be too fat or too thin, they should have a
good large scrotum, that way they're healthy
to be reproducing.
It's always good for bulls to get a semen test, get your
local vet out, do a test, and that way you know if
they're able to be fertile and reproduce for your girls.
Finally, with bulls, it's always good to keep an
eye on them, make sure they're all following their girls
around and they're still happy in their herd.
If you have a few bulls that are continuously fighting with
each other, obviously they're focusing on each other more
than the girls, and they may not be able to be serving
your girls efficiently.
Also, after bullying between the bulls, sometimes one may
get a bit sulky and hang away from the girls.
It's always best to keep an eye out when you're mixing bulls in
one herd so that they're all working, and if not,
switch them out and make sure they all have friends.
When looking at your cows and calves, it's always good to
take note of their udders and who's feeding who.
This girl here, owns this little heifer,
and her udder is beautiful.
It's nice and perky, full of milk and the teats
don't show any signs of discomfort.
And also, it's good to take note if any cows are dry,
that means their udders will be shrivelled up, not full
of milk, and there will not be a calf sucking her.
When checking cows and calves in the paddock, it's always
best to have a look if any cows are bellowing or searching
around looking for a calf.
This calf may be lost, sick or in worst case scenario, dead.
When you're in the paddock searching for calves or
moving cows, it's always good to be aware of long grass,
or the fact that calves are really good at laying down and
hiding from people, so be very careful when you're traveling
around in a paddock in case you come across a calf.
When you're moving cows and calves to a new paddock,
it's always good to take note of distance.
Sometimes it's best if you just open a gate and let them make
their own way through to the next pen, rather than moving
the cattle through several paddocks where there is a
higher chance of leaving a calf behind or a calf
getting overly tired.
When checking cows and calves each day, it's always
good to take note of who's cycling and who's springing.
So if your calves are about to come on the ground, when they
spring cattle start to get really soft around the backside
and their udder starts get nice and perky as they
produce milk.
You'll also sometimes see a string of goo coming from
their back end.
When cattle are cycling, it's always good to take note
of who the bulls are chasing as well.
When checking cows and calves each day, it's also good to
take note of any calves that appear woody or thin – another
calf may be stealing milk, or the cow may not be producing
enough milk for the calf, or the cow not being a good
mother and not letting the calf drink.
You should also take note if the calf has scours, that is,
discoloured poo or runny poo, and it will cause a calf to
get very sick.
Also, if a cow's udder is really bulging and full and she
seems uncomfortable, she may have lost her calf, so it's
always best to have a look around to see if any cows have
bulging udders, as well as dry udders, or bellowing
around searching for a calf.
