CoPulsationTM Milking System
Mastitis – Root Cause
• Bacteria responsible for udder infections
• Milking machine is the delivery system
– Core of the milking machine (liner, pulsation) provide
the cow to milking system interface
– The design and performance of milking system effect
teat condition, milking action and cow behavior
– Evidence proves that an incorrectly designed milking
system significantly increases mastitis
• Creates environment for bacteria to enter the teat sinus and
udder

Milking Machine – Delivery System • Dr. Derek Forbes research proves liner pinch forces bacteria up teat
sinus
• Cornell University research proves conventional pulsation causes 16X
more Staph aureus infections than CoPulsation
• Dr. Sybren Reitsma shows short D phase increases new infections
• Teagasc proves teats swollen and injured by conventional milking
machines
• More claw vacuum fluctuation events with alternating and sequential
pulsation
• “the milking machine is one of the best washing machine ever built,
the teats are bathed with milk during the milking process” – Dr. Andy
Johnson: 2000 NMC Annual Meeting
• Atlantic Vet College research shows >23% of teats not sealed 6 weeks
after dry off

Dr. Forbes Research
• Milk samples extracted from teat end
and directly from teat sinus
• Bacteria present in teat end for many
days – no mastitis
• Teat end pinched by liner – forced
bacteria up sinus causing new
infection
• The pinching action of conventional
milking machines can be felt with
your fingers in the liner

Cornell University Research • Compared GEA to CoPulsation
• 30 best cows from CU herd
selected
• 15 cows in each group milked 6
months and switched
• First group milked by
CoPulsation started with 5 Staph
A cases caused by GEA
• Final result: 1 new Staph A
infection with CoPulsation and
16 new infections with GEA
• Supports Forbes research
• Study duration to short for teat
health improvement based on
averages

Reitsma Research – D duration • Compared infection rates for
different liner closure (D phase)
durations
• Short D phase causes more
infections
Consider the following:
• Anatomy of teat and time for blood
recirculation requires D phase of .4
to .5 seconds
• Example: tightly squeeze your
forearm, release and note time it
takes for redness to go away

Teagasc Research
• Research at Teagasc in Ireland
proves conventional milking
machines cause teat swelling
and teat sinus injury
• Evidence that conventional
milking machines cause the teat
to swell (congestion) while
milking and experience
physical damage to the teat
canal and teat sinus

Simultaneous vs. Alternating Pulsation
• 2X more vacuum fluctuation events with alternating
• Claw vacuum fluctuation during milking interrupts
milk flow and causes backwash
• Alternating originally designed to allow front
quarters to milk 50:50 and rear 60:40 and never
reduced mastitis as claimed – no one uses alternating
pulsation as originally intended
• Claw vacuum stability with simultaneous is as good
or better than alternating with proper venting and
claw volume

Objective Observations • Many facts can be visually observed proving that
conventional milking machines cause physical harm, pain
and result in high rates in new infections
– Teats soaked in milk – backwash
– Teats swollen and reddened
– Teat sinus injury – lightly pinch and roll teat end and fell scar
tissue within teat
– Milk flow never stops during the rest phase, it only slows down
– Feel pinching action of liner with your finger
9
Abundant research and observations exist to support the fact that conventional
milking machines are the delivery system for bacteria causing the conventional
milking system to be responsible for new infections

Summary • Significant proof exists showing that conventional milking
machines are the delivery system for mastitis
• CoPulsation solves every problem caused by conventional
milking machines
• Quality milk, low antibiotic use and low cull rates can only
be achieved with CoPulsation
• It is important that the other parts of the milking facility be
correct – vacuum regulation, detacher settings, pipe size
and design
– Milk must flow freely from the cow
– Vacuum supply must be proper and consistent

Known Problems with Conventional
21
Alfa Laval Agri
United States Patent 5,697,323
Issued December 16, 1997
In milking machines currently marketed by Alfa Laval, the
pulsation chamber…. The relatively strong milking vacuum is
needed primarily for ensuring a safe attachment of the teat cups to
the teats and, secondary, for achieving a rapid milking and a high
milk yield. However, a disadvantage of such a
strong milking vacuum is that it might treat the teats roughly,
especially at the beginning and at the end of the
milking interval when there is no or insignificant milk flow
through one or more teats. Attempts have been made
to eliminate this disadvantage by milking according to
different…
WestfaliaSurge patent application:
During traditional manual milking, which is a pressure
milking
method, almost the entire amount of milk present in the
udder can be milked. In the
machine suctional milking method there is a problem,
first of all some
quarters are milked too long although no more milk flow is
present, and, on the other
hand, in individual quarters, the milking process is ended
too soon and
therefore residual milk remains in the udder.
Delaval, WestfaliaSurge, Boumatic and others have known for many years that problems
exist with their milking machines. They have made many attempts to solve those
problems with no success.
Goran Olofsson, past VP Engineering for Delaval: “you have done what I have tried to
do for over 25 years”

Teats not milk-wetted
• Teats wetted with milk during
milking process – contaminated
with bacteria
• “ Since the milking machine is
one of the best washing
machine ever built, the teats are
bathed with milk during the
milking process. ” – Dr. Andy
Johnson, 2000 NMC Annual
Meeting
• CoPulsation does not wash the
teat in milk

Scientific Evidence • University study (Journal of Dairy Science)
– 16:1 reduction in new Staph aureus infections
– Study duration (1 year) too short to evaluate environmental mastitis, more time required to improve teat canal health
• Multi-year side-by-side study (Int’l Dairy Topics) – Small commercial herd
– University based data – SCC levels reduced 75% with CoPulsationtm
– Overall mastitis levels reduced 50% with CoPulsationtm
– Contagious mastitis virtually eliminated with CoPulsationtm
• Teat condition study (Int’l Dairy Topics) – No teat swelling caused by CoPulsationtm
• Milk flow study (Int’l Dairy Topics) – Peak flow rate maintained for about 2/3 of milking duration to only about 1/3 of
duration for conventional
– Milking time about 10% to 20% faster with CoPulsationtm

Performance benefits • Compressive liner action massages teat for a gentle, pain free milking
– No teat swelling, no canal damage, no milk wetting of teat
• Eliminates teat end pinching by liner, prevents reverse milking action by not forcing bacteria through the teat canal
– Calm cows, no liner crawl/squall
• Milk flow fully stops during rest phase allowing tissue around the teat canal to rest
– No teat canal damage, canals close quickly
• No milk back flow
– Prevents bacteria contamination of teat
– Teats dry when machine is removed
• Efficient milk let down
– Longer duration at peak let down
– Quick completion of milk out works well with auto-detachers

Questions to ask
• How will you cut antibiotic use by 50% in
two years?
• How will you increase the average life of a
dairy cow by 2 lactations by 2020?
• How will you prevent udder and teat
damage?

Summary
• Consider two conclusions:
– Mastitis is a symptom of management (Utrecht
Mastitis Conference 2011)
– Mastitis is a result of a failure to provide the
cow with the proper milking environment
• Given the information provided, which
conclusion best supports the evidence and
experience on dairy farms?
The dairy industry has taken the path of blaming management for 50 years
and still mastitis is the most expensive problem on the dairy farms
