this time we’re looking at something
which has been consumed by mankind for
thousands of years we’re talking about
milk how is milk created well in fact a
cow has four stomachs the first stomach
begins to break down the grass before it
passes through the second and third
stomachs
we’re nutrient absorption begins
eventually in stomach number four
gastric juices finish off the digestion
process and nutrients extracted from the
food are absorbed into the bloodstream
in the udder the blood passes through
very small blood vessels surrounding
groups of secreting cells called alveoli
it’s these that actually produce the
milk using the nutrients carried in the
bloodstream aside from the food they eat
cows must also drink plenty of water 18
litres of it to produce just four and a
half liters of milk and the traditional
way of milking a cow was of course by
hand using a stool and a bucket and I’m
gonna give it a go
farmers going back to the iron age
milked cows in this way joy is that the
first time you’ve done that yeah she’s
always been very full because that’s
coming out without much encouragement
but it’s not as easy as it might seem
there you go girls the average cow
produces about 27 liters of milk a day
but it has been known for cows to
produce more than a hundred liters in a
day and you can drink the milk straight
from the other as I am about to
demonstrate yeah there we go whisky
there we go that is absolutely delicious
technology has entered the world of the
Mucca Richard and Johnny have come to
one of the most modern dairy farms in
Britain where a laser-guided robot milks
the cows it’s called an automated milk
Harvester and it operates 24/7 allowing
the cows to enter at their own free will
so talk us through the process how does
it work
okay the cows walk on from this side
come into the box and stand there
they’re identified by a microchip which
they have in a collar on their necks the
computer will then decide whether it
wants to milk this cow or whether to let
this one go and take the next one so
it’s trying to be as efficient as it can
it’s always looking to harvest the
maximum amount of milk every 24 hours
why would it let’s account go then why
would it not milk one if she doesn’t
have enough milk in her owner
it won’t invest six and a half minutes
of its time for a small amount of milk
it’s looking for a cow with about ten
litres of milk
I’m sorry just explaining how does it
know whether it’s worth milking her it
keeps a running total on every cow in
the herd can then calculate within half
a litre how much milk is in the cow
before it starts the milking and homely
cows have days at milking it’ll milk 70
cows three times a day can do about 200
milkings over the 24-hour period and
what’s the most Sayre calcaneal we’ve
had cows on here that are given 100
litres in the 24-hour period that’s me
which is extraordinary
once the robot has committed to milking
a cow a brush system first cleans and
sterilizes the teats with hydrogen
peroxide to prevent any infection being
passed on the orange brush then massages
the cow’s udder to encourage the
production of the hormone oxytocin which
is needed to stimulate the milk flow the
milk comes down through these tubes
ghosts
this electronic box and there’s 10,000
pounds are the sensors in there which
monitor the quality of the milk it can
see watery substances cow mark dirt pull
out anything which isn’t normal in the
milk it will see it and then it
separates that milk out into these
buckets and then when the process is
finished takes about four seconds to
chill the milk down from 37 degrees down
to two degrees goodness me and is not
just the milk that’s chilled this system
can prove much less stressful for the
cows in fact on this farm they’re
actually living an average of 30 percent
longer than those on farms where they
use more traditional milking methods but
what happens if something goes wrong
with milking when the farmer is not
around
well this technology is so advanced the
robot just contacts him over the phone
the system actually automatically
contacts you if there’s a problem it
does yeah we’ll ring me immediately
within seconds of identifying a problem
there are about a hundred sensors on
here that can all detects whether it’s
working correctly or not any one of
those finds a problem brings me straight
away gives me a message to tell me what
the problem is I can then text back
codes to try and fix the problem where I
am or even if I’ve got my laptop and a
wireless broadband connection I can
connect on anywhere in the world using
the cameras I can see what’s going on
and I can use my keyboard to sort the
problems out
