Mister Cows offers a cooling solution for dairy farms to reduce heat stress in cows, which can improve milk production and enhance animal welfare. The system includes a misting kit that can provide a cash benefit of approximately $3,774 AUD over 20 days during extreme heat, with an investment cost of $2,589 AUD. Successful installations have been reported, leading to cooler environments and reduced fly presence in milking areas.

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?
