Our first installation of MisterCows become a success. It has been installed on a Dairy Farm, Victoria, Australia. Farmer comments has been: it really cools the yard and keeps flies away. Please see the details and come back with questions and hopefully - orders. Your's, Ivan Perov.
1. MISTER COWS
Your cows are coooooool

2. MISTER COWS – WHY?
DAIRY cows – perform 10% less in milk production
due to a heat stress as they stand for 3 hours in a
waiting area*
BUT, I believe that even when the cow will yield 1
litre more of milk per milking at every hot day* in
addition to the normal yield it makes a significant
difference.
Not much? Let’s see HOW MUCH it is in cash flow
(are we really after the cash flow?)
* In Australia definition for extreme HOT DAY is when
the Temperature goes above +30°C

3. MISTER COWS – WHY?
Although I would agree that assumption is a mother of failure, lets assume*:
30 days per average year with extreme hot days above +30C
1 litre of milk (farm gate price) – 0.48 cents AUS
Average commercial dairy herd is 260 cows
Cash benefit for installing “Mister Cows” solution for an average farm
is:
$0.48 @ 30 days @ 260 cows = $3774 AUS
Question: Would the +25°~27°C be also regarded as extreme
temperature for dairy cows?

4. MISTER COWS – your $3774 AU cash
benefit solution In addition to YOUR happy
cows, misting kit will include:
Misting pump – 1 pcs
Misting nozzles – 70 pcs
Fittings and joints – 70 pcs
Elbows
100 meters PE pipe (9.2
mm)
Pipe cutting tool – 1 pcs
Complete installation
5. MISTER COWS – your cows cash
benefit solution
$3774 AUS (Your farm Cash Benefit).
$2589 (the price for Mister Cows solution) divided by 260 cows divided
by 0.48 c/aus (farm gate price) = 20 days
This is the number of days the system
will pay back.
Question: Can we do an economic estimation of
general cow improvement due to a comfortable stay in
a waiting area for 3 hours* (see next slide) that we can
not directly evaluate?

8. MISTER COWS – 1 litre of milk in one HOT
day on your 260 dairy cows herd
Will save 260 litres of milk because of the heat stress
reduction. And will generate $124.8 AUS per
single HOT day
Or $3774 AUS additional cash in 20 days
(average number of extreme heat (above +30C) a year.
