2023 Tirlán Dairy Hygiene Products

For more information on how to avail of our extended credit offering please contact your local Tirlán FarmLife Representative.

INTRODUCTION

Dear Milk Supplier,

Included within this leaflet is a listing of the recommended dairy hygiene products available from Tirlán, alongside guidance notes towards their use on farm. The products recommended in this brochure are backed by Teagasc research and have been specifically chosen by the Tirlán Milk Quality and Veterinary advisory teams based on proven quality and reliability when used correctly on farm. The wide assortment of available products allows you to choose the products most suitable for your herd’s approach to dairy hygiene. These products, when used correctly, will assist in keeping TBC, Thermoduric and SCC levels low on farm.

Both dairy detergents and teat care products play an important role in quality milk production on your farm. Dairy detergents are required for effective cleaning of the milking machine and bulk tank. Teat care products on the other hand are critical for teat hygiene and mastitis control and play a vital role in lowering the bacterial load on the teat skin, thereby reducing new infection rates by up to 50% and reducing the risk of TBC and Thermoduric issues.

Tirlán places a significant importance on the selection of these products in milk quality terms, as they are one of the few farm input categories that can come directly in contact with milk. The products used in the parlour and dairy can have a significant impact on milk quality, and particularly on residues in milk. As you will be aware, due to customer and regulatory requirements regarding chlorate residues in finished dairy products, all chlorine containing detergents and teatdisinfectants are specifically banned from use on Tirlán supplying farms.

Increased consumer awareness, along with better detection methods has led to the control of residues becoming a priority area in recent years so that Tirlán dairy products can continuously meet and exceed customer expectations.

With our focus on the production of residue-free milk of the highest quality you are encouraged to consider Tirlán as a trustworthy provider of dairy hygiene products for your farm. The Tirlán FarmLife sales teams of Branch and Business Managers will provide full product support while Tirlán Milk Supply Managers are always available for full technical backup on the correct use on your farm.

ESSENTIAL - REVIEW YOUR HOT WATER PROVISION

How do Detergents and Hot water work in wash routines?

Caustic detergents remove organic residues from milk (the fats, proteins, carbohydrates (sugars) and typically contains substances such as sodium hydroxide. Usually the higher caustic concentration the more effective the product will be.

Acid products deal with mineral deposits (which are mainly from your water source) such as Calcium, magnesium, iron etc. They tend to contain active ingredients such as phosphoric and nitric acids.

Peracetic acid is an add-on steriliser for final rinsing – it doesn’t replace acid detergents or caustic. It is the add-on at the end that will ensure your plant stays sterile between milkings.

You will need different amounts of each of these products to ensure your wash routine works well.

What you are trying to avoid is allowing bacteria to build up a protective bio-films which makes them harder to remove. Where a build up of milk residue occurs on surfaces such as the receiving jar or claw-pieces –this shows your wash routine isn’t working and will allow biofilms to build up and harbour thermoduric bacteria.

Key to a good reliable wash routine is to ensure you have sufficient hot water. You need to ensure you have a wash trough that can take the required volume of water – this is vital to success. Where the water volume

Wash Routines

14 litres of fresh water per cluster unit for the first rinse.

This cold water rinse washes out as much milk residue and dirt as possible

Water Softener

Hard water or mineralised water containing iron etc will impact the detergent efficacy. You will need to use a water softener and possibly have a more frequent rotation of caustic and acid detergents.

There are several heating options for hot water in the dairy:

• Electrical water heating

• Oil fired water heating

• Gas water heating

• Solar Photovoltaic (PV) Unit

• Heat Recovery Unit

9 litres of fresh water per cluster unit for the main detergent wash: this wash cycle eliminates protein and fat from the system.

An acid wash rotated here (as per the manufacturers guidelines) will eliminate any milk stone build up and mineral deposits.

The acid wash needs to be hot and short - if the water cools down it will not be effective.

Hot Water Checklist

Invest in an optimum sized water heater / heat recovery unit.

Heat sufficient hot water for your machine and bulk tank – ensure you can wash both on the one day.

Have a separate heater for water for the tank and machine in case of breakdown.

Temperature should be 7585ºC at start and 45-55ºC when finishing circulation. Use a thermometer to check water when it is circulating and when it is in the wash trough to confirm what the wash temperature actually is.

isn’t enough – the wash water won’t be able to take the dirt / milk residue out of the lines and it will get left behind to build up.

The hot wash water temperature is key and must be at 75ºC at start point and run to waste at 55ºC. Any cooler and you just won’t get an effective detergent solution mix and the cleaning won’t be effective. A key action is to pre-rinse the lines with hot water as the start of the wash cycle so they are warmed and the detergent wash water stays hot. Your hot wash cycle should only be 8 -10 minutes long.

Ideally then follow with one final rinse and include peracetic acid. This will sterilise the clean plant and will ensure all build up and deposits in the plant are pushed out and ensure the lines are left as clean as possible.

How much detergent should you use?

It depends on the water quantity in your trough.

FIRST RINSE DETERGENT RINSE FINAL RINSE PERACETIC ACID RINSE

No milk residue (milk stone) build up on the sides of the tank Check for build-up in claw pieces - look for gel biofilm or visible milk residue build up

Periodic service completed Check for build-up in vacuum line every two weeks

Make sure that wash water is not dirty or being reused Service and repairs should be completed every six months

Ensure that the gas is not running low

Wash trough must be big enough to give sufficient water volume to ensure good thorough rinse and wash cycles

Temperature probe fully functioning Sufficient turbulence to clean all the surfaces (air and water)

Water with a high sediment / dirt content No maintenance Housing feed systems with sufficient access and clean

Caustic content too low for effective washing System blocked Sufficient cubicle space

Acid percentage too low Pipes not sucking up enough detergent No detergent in drums

Peracetic acid not being used as a steriliser

Detergent not containing the right quantity of caustic

Detergent drums not rotated frequently enough

Good post milking teat disinfection

Good pre milking teat preparation routines

Non dusty feeds in the dairy

Agitator working correctly Manually adjust any 3 Way Valves at points to ensure correct cleaning e.g. at the receiver jar, plate cooler

Water volume too low for effective cleaning

Use clean fresh filters at every milking Hot water not hot enough (75oC) Fully clean receiving jar Cold rinse cycle not immediately following detergent washes Check milk metres / individual jars for build up Hot washes being allowed to run to cool / cold Check for pipe work that is not being fully cleaned - look for areas that the wash water can’t access

QUALITY OPTIMUM TARGETS

Detergents not being used in right rotations Controlling mastitis and high SCC No issues with electricity supply Check the Sanitary Trap Not enough acid washes Clean gloves at all milkings Ensure compressor fans are clear and not clogged with dust Avoid build up in the plate cooler, protect the plate cooler by using a filter both during milking or wash cycles

BENEFITS OF TEAT CARE

Reduce bacterial load Improve teat skin condition

Produce high quality milk 1 2 3

Application of teat disinfectant

Post-milking teat dipping or spraying has been in use for several decades and significantly reduces the rate of new mastitis infections by 50%.

Pre-milking disinfection is becoming more common and has its uses under certain conditions. The full benefit of teat disinfectant is only achieved when it is applied efficiently and effectively. Product effectiveness depends on the formulation as well as the application. The type of active ingredients and their concentration determine product formulation. For concentrate product mixed on-farm, mistakes in dilution and water quality can have a huge impact on product effectiveness.

To eliminate product variability, ready-to-use (RTU) products are strongly recommended.

The most common error in teat disinfection is failure to cover the entire teat of every cow at every milking. All the benefits of correct product selection, mixing and storing are lost if disinfectant is not applied correctly. The skin of the entire teat has to be covered in disinfectant, i.e. every area that touches the cluster liner. As long as there is plenty of disinfectant in the dipping cup, adequate cover of the teat skin is easily achieved. Spraying can achieve similar levels of cover if at least 15 ml of disinfectant per cow is applied to the teats immediately after each milking.

Fully functional spray equipment is crucial to support adequate teat cover in the shortest time-frame. Although time-saving, the drawback of spraying is a much greater chance of achieving only partial teat cover compared to dipping. If the far side of teats is consistently lacking disinfectant, a reservoir of bacteria may develop.

How teat disinfectants work

Mastitis causing bacteria such as Staph aureus can remain on the teat cup liners for up to 9 milkings. This means that infection can spread from one cow to the following 9 cows milked on that same cluster. Post-milking teat disinfectant should be applied as soon as the cluster is removed. This allows the disinfectant to enter the teat canal through the still open teat-end and kill those bacteria that entered the teat canal during milking. On the teat skin surface, post-milking disinfectants remove mastitis causing bacteria and speed up the healing of skin lesions and treat chapped skin. In this way, bacteria that spread during milking are removed ahead of the next milking, which makes post-milking teat disinfection an extremely effective weapon against the spread of contagious mastitis. Cows should remain on their feet for at least 30 minutes after milking for the disinfectant to fully work.

Pre-milking teat disinfection has a similar effect on bacteria present on the teat, especially around the teat end. This can be very useful where environmental mastitis is a concern, during housing or in early lactation in spring calving herds. However, pre-milking dipping or spraying does not prevent the spread of mastitis pathogens from one cow to the next during milking. Pre-milking disinfectant should be applied after the cows have been fore-milked or stripped and needs a contact time of at least 30 seconds after which it is wiped off by paper towel before the cluster is attached. Not every teat disinfectant is suitable for pre-milking use and manufacturer guidelines need to be followed to prevent residues in milk. For these reasons, pre-milking teat disinfectant is not suitable for every herd and its application may not show an improvement in SCC if not used correctly.

Teat disinfection is an integral part of good milking practice and adequate teat care is vital in any mastitis control programme to:

Research from Teagasc has shown that teat disinfectant products containing chlorhexidine or a combination of lactic acid and chlorhexidine are most effective against the main mastitis causing bacteria found in Ireland.

Improve udder health in the parlour

Milking routines should be aimed at reducing the risk of spreading mastitis causing bacteria between cows. The milking routine should be designed so that every cow is milked exactly the same at every milking, regardless of stage of lactation or milker. The ultimate target is to consistently keep SCC below 150,000 cells/ml and a good milking routine will help achieve this target.

Clean gloves, not over-milking cows, frequent parlour maintenance to avoid faulty vacuum and changing liners every 2,000 milkings all contribute to better udder health.

However, as research shows, correct postmilking teat disinfection reduces mastitis by 50%, it is the single most important step in mastitis control.

Teat Care Top Tips!

Only attach teat cups when teats are clean and dry.

Wear clean gloves during milking. Inspect foremilk for signs of clinical mastitis.

Use Pre-milking disinfectant when necessary and dry wipe teats.

Attach clusters as soon as possible after preparation.

Shut off vacuum at the claw-piece and remove clusters when milk flow ceases.

Adequately dip or spray all teats of all cows as soon as possible after every milking with a suitable postmilking teat disinfectant.
