Hybrid® Inflations can be implemented with nearly all milking systems.
Attributes of Hybrid® Inflations
• The HYBRID® inflation uses the round inflation that fits the Cows teats properly (reduced squawking)
• Unique design causes the inflation to collapse in the shape of a triangle (wall over™)
• Equivalent or greater milking speed to a round inflation
• Superior massage action of a multi sided inflation
Venting of Air Into the Milk Stream
Venting of air into the milk stream is very important with high producing cows. Venting allows the milk to move quickly away from the teat of the cow.
There are many ways of venting:
• Vent in Shell
• Vent in milk tube
• Vent in Claw
• Plastic nipple that is between the inflation body and the milk tube
• The best location is when it is closest to the source of the milk
Most claw vent openings are 0.040 inches or 0.00127 sq. inches.
Hybrid inflation is .023 or 0.000415 sq. inches.
Multiplied by 4 = 0.00166. (slightly larger than the claw 0.040 diameter)
There is more friction going through the 4 small orifices of the Hybrid making it equal in volume of air going into the milking system
Air Venting Advantages
Bou-Matic, Milk-Rite and the Conewango vent all are around 0.400 deep. The IBA vent would be similar in depth
The Hybrid vent is almost impossible to clog compared to others with the exception of the Bou-Matic vent which also has the smaller opening on the outside
Milk-Rite, Conewango and IBA have the small opening on the inside of the vent (tapered from the larger opening on the outside and getting smaller as it transitions to the flow of milk which can cause more plugging
Hybrid Modular Design
• Head section requires good resistance to body fats and teat protective products
• The head section acts as a holding mechanism and a vacuum retainer to keep the inflation from falling off during milking
• Most important section although each component relies on the best performance from each other
• This is where the milk is extracted from the teat orifice. The top portion of the barrel is predominately in contact with the teat and is where some massage action takes place
• The lower portion does the major flexing and massages primarily the lower 1/4 of the teat along with creating the shut off mechanism to close the constant partial vacuum to the teat
• The barrel requires oil resistance (fat from milk) but it’s major requirement is speedy opening and closing (flexing dynamics)
Plastic Used In Hybrid
The product is made from an Eastman Tritan Copolyester product that is an approved plastic used for repeated use food-contact articles under 21 CFR 174.5 (d)(5)
1.Conveys milk from the shell to the claw
2.Requires almost no oil resistance
3.Must be very flexible
4.Must be resistant to oxidation attack
5.Requires a high degree of cut resistance because of claw cutting.
Air tubes or (pulsation tubes) are generally made from EPDM and SBR rubber since the materials in combination are quite strong, flexible and are ozone resistant.
Tarp straps are a good example of the materials ozone resistance.
Milk Quality: Hybrid Inflations
• Improved teat end condition
• Reduces cost per milking – Traditional Inflation: 1200 milkings vs Hybrid Inflation: 8,000 – 10,000 milkings
Milk Quality Management & Goals
< 1% milking herd treated and milk discarded
< 200,000 somatic cell count
< 5000 standard plate count
Milking Prep Routine
• Dry wipe, sand & dirt off
• Fore strip
• Wipe dry – use 2 towels
• Attach milking unit
Inflation Types Available Today
• Round inflations have been the mainstay over the past 100 years.
• Easy to manufacture
• Teats are round and will glove fit the animal
• Best design for milking speed in the past
Oval or Pre Collapsed Inflations
• Not popular because of slow milking
• New to the market 25 years ago
• Improved designs have made great inroads because of the massage action
• May have a loss of milking speed compared to the typical round inflation
• Been in the market for about 10 years
• Good for teat and udder health
• Slow milking because due to the design (flat walls will not spring back like a round Inflation when collapsed)
• Recent development
• Collapse similar to a round inflation with the expectation that they will self adjust to different teat sizes
• Silicone rubber has been used to a limited extent in manufacturing inflations over the past 15 years.
• Draw backs to silicone – Silicone has very poor tear qualities and can easily be punctured.
• It has great ozone protection and oil swell properties
• Excellent softness with teat contact
Milk Quality – Hybrid Inflations
Improved Teat End Condition
• Rough teat ends hide bacteria
• Reduced mastitis when teat ends are a problem
Importance of Teat End Health
The teat canal is the primary physical and chemical barrier to invasion of mastitis pathogens into the udder. Between milkings, the smooth muscles surrounding the teat duct should be contracted and the teat canal tightly closed to impede bacterial passage from the teat orifice into the interior of the gland.
A teat-end in good condition is an important resistance factor to bacterial colonization of the mammary gland.
Changes in teat tissue by milking, teat canal integrity, and teat tissue pliability may favor penetration of bacteria into the udder.
Callosity Ring or Hyperkeratosis
With thick callosity, the outside portion of the teat canal might not close as tightly and micro-organisms may penetrate further into the canal.
The surface of the callous ring can become rough (category 2).
Rough callosity provide crevices for pathogenic bacteria to lodge, thereby making full teat disinfection more difficult and increasing the risk rate of new intra mammary infection.

• Fore stripping and full prep mandatory
• Keep air vents clean, clear
• Change milk tubes every 5,000 milkings or when needed
Works with most Milking Parlours
Jetter Cups Available
• The Hybrid® inflation comes as a set of 4 (ea) inflations complete with shells inflations vented nipples and air and milk tubes.
• There are 3 different milk tubes available which are of different hardness depending on the style of claw you are using.
• The sets also come with either a 1/4″ ID or a 9/32″ ID air tube.
• Air vents are located in the plastic nipple between the shell and the milk tube for quickly evacuating the milk from the inflation to the claw.
• Both jetter cups and manifold cups are available for in/place washing for most systems.
• Fore stripping and full prep mandatory
• Keep air vents clean, clear
• Change milk tubes every 5,000 milkings
• Cows need a short time to adjust to the new process
