<strong>Shorter</strong> milking time thanks<br />

to dry udder <strong>cleaning</strong><br />

Preparation for milking involves both <strong>cleaning</strong> the udders and teats and also stimulation of<br />

the cow to encourage the release of oxytocin. In addition, optimal preparation for milking<br />

means shorter milking time. A trial in France showed that dry <strong>cleaning</strong> with pre-milking<br />

delivers the best results.<br />

.<br />

Whenever possible udders and teats should be cleaned with dry disposable materials. Material used for dry<br />

<strong>cleaning</strong> must be soft, but nonetheless with good tactile properties, dry and absorbent.<br />

T<br />

he preparation of the<br />

udders and teats<br />

before milking is<br />

part of the daily work routine<br />

on every dairy farm. Various<br />

goals are pursued with this<br />

routine work at every milking<br />

session: One goal is the<br />

normal <strong>cleaning</strong> of coarse<br />

dirt such as faeces and straw<br />

from the udders and teats.<br />

Another is that preparation of<br />

the udder should stimulate the<br />

cow, so that sufficient<br />

oxytocin is released (as was<br />

reported in Issue 3/11 of "die<br />

grüne").<br />

The release of oxytocin<br />

causes the milk to be injected<br />

into the cistern cavity of the<br />

udders and milking can be<br />

completed in a shorter time.<br />

Moreover, by pre-milking the<br />

udder, the milk is checked for<br />

visual mutations. There are<br />

various methods by which<br />

these goals can be met.<br />

Depending on what type of<br />

working materials are used<br />

for <strong>cleaning</strong> the teats there are<br />

fundamental distinctions<br />

between dry, moist and foam<br />

<strong>cleaning</strong>.<br />

Disposable udder paper<br />

and udder wool for dry<br />

<strong>cleaning</strong><br />

Whenever possible udders and<br />

teats should be cleaned dry<br />

and stimulated. Wet or moist<br />

<strong>cleaning</strong> can reduce the<br />

adhesion of the milking<br />

cluster and thus lead to<br />

fluctuations in the vacuum,<br />

which increases the<br />

mechanical contamination of<br />

the udder. Therefore after<br />

every wet/moist <strong>cleaning</strong>,

the udder should be dried in a<br />

second step in the process, which,<br />

however, lengthens milking time.<br />

Material used for dry <strong>cleaning</strong><br />

must be soft, but nonetheless with<br />

good tactile properties, dry and<br />

absorbent. <strong>Udder</strong> papers satisfy<br />

these requirements, as does<br />

agroclean® udder wool from<br />

Lindner. Because of the naturally<br />

occurring essential oils and resins<br />

this special udder wool has an<br />

additional antiseptic effect.<br />

Here it has to be stated<br />

that the<br />

requirements for udder wool for<br />

<strong>cleaning</strong> the udders (soft and<br />

with good tactile properties, dry<br />

and absorbent) cannot be<br />

found in conventional or cheap<br />

wood wool from any old<br />

company. The wood wool in the<br />

illustration at the top left of<br />

the next page exhibits edges<br />

like saw blades. The effect on<br />

the teats of wood wool like this<br />

can be compared to <strong>cleaning</strong><br />

with emery paper and leads<br />

to minor injuries and cuts to the<br />

skin.<br />

The use of moist cloths has<br />

become established as an<br />

alternative to dry <strong>cleaning</strong>. Moist<br />

cloths are made from disposable<br />

material - usually paper - or in the<br />

form of disposable textile cloths.<br />

and is then washed and spun in<br />

In the trade many unsuitable types of wood wool are supplied for udder <strong>cleaning</strong>. What makes agroclean® udder wool different is<br />

This type of material is highly likely to injure the udder. the width and strength of the fibres which do not shed dust or split.<br />

.<br />

Therefore the <strong>cleaning</strong> agents for<br />

the moist cloths usually also<br />

contain a conditioner.<br />

Products advertised as<br />

supposedly progressive teat<br />

cleaners use active foam for<br />

<strong>cleaning</strong> the teats. After the foam<br />

has been applied on to the teat by<br />

dipping, it must be left to take<br />

effect for at least 30 seconds. In<br />

this time the foam dissolves the<br />

dirt from the teat and encases it.<br />

Next, in a further work step,<br />

Stimulation influences<br />

milking duration<br />

The preparation of the udders and<br />

teats is not done simply with<br />

<strong>cleaning</strong> in mind. Stimulation<br />

encourages injection of the milk<br />

and therefore also swift milking.<br />

Centre of Healthy Dairy Products<br />

in Burgundy in France compared<br />

four different preparations for<br />

4 LIVESTOCK BREEDING | Preparation for milking die grüne | Nr. 8/2011<br />

The purpose of milk preparation is on one hand the <strong>cleaning</strong> of udders and<br />

teats, and on the other, the stimulation of the udder.<br />

Alongside the usefulness of<br />

preparation for milking the<br />

costs of various pre-treatments<br />

must also be taken into<br />

n Which drying<br />

procedures are the most<br />

widespread in the industry?<br />

Thomas Manser: <strong>Dry</strong> or moist paper<br />

and wood wool are the processes<br />

most often used.<br />

n When and for which<br />

types of dairy farm is it<br />

appropriate to use the three<br />

<strong>cleaning</strong> techniques (dry,<br />

moist or foam <strong>cleaning</strong>)?<br />

When there are no problems with<br />

the health of the udders or with<br />

cheese dairy specific tests, dry<br />

<strong>cleaning</strong> is sufficient. Moist<br />

<strong>cleaning</strong> is more thorough. The<br />

effect is clearly seen when for<br />

testing purposes dry<br />

<strong>cleaning</strong> is followed by <strong>cleaning</strong><br />

with a white, light moist paper.<br />

Foam <strong>cleaning</strong> is a variant of<br />

moist <strong>cleaning</strong>. Foam <strong>cleaning</strong> in<br />

the milking parlour is easier than<br />

in the stanchion barn because an<br />

extra<br />

account. The table on the<br />

previous double spread<br />

compares the costs of<br />

different products which<br />

cup is employed. The foamer should<br />

be used for about 30 seconds for<br />

optimum effect. Afterwards the udder<br />

must be wiped with dry paper. It is<br />

also important that this cup is clean<br />

and filled only to the amount required<br />

during a single milking. Otherwise<br />

there is a danger of crosscontamination.<br />

n What influence do the<br />

husbandry system and stall<br />

hygiene have on the choice of<br />

<strong>cleaning</strong> procedure?<br />

Irrespective of the system the teats<br />

should not be extremely contaminated.<br />

Of course that does occur from time to<br />

time. However, when an udder shower<br />

is necessary for every second cow, it is<br />

less a question of considering whether<br />

to use another <strong>cleaning</strong> process and<br />

more a case of needing to take a<br />

hard look at the care of the lying<br />

areas and the alleys.<br />

Best quality agroclean® udder wool<br />

The Lindner Suisse company<br />

f r o m W a t t w i l ,<br />

S t . G a l l e n manufactures<br />

the agroclean® udder wool<br />

by an ingenious, p a t e n t e d<br />

p r o c e s s . T h e cornerstone<br />

for the quality of the end<br />

product is laid right at the<br />

beginning of the process with the<br />

purchase of the wood and the<br />

way it is stored. Only wood free<br />

of knots from FSC and<br />

PEFC certified Swiss forest is<br />

used. This wood is debarked<br />

and cut into metre long<br />

lengths and<br />

arise per milking session and<br />

per milking parlour. <strong>Dry</strong><br />

<strong>cleaning</strong> with agroclean®<br />

udder wool is the most costeffective<br />

in comparison with<br />

products for wet/moist and<br />

“In all procedures it is good practice<br />

to use fresh material for each cow”<br />

Thomas Manser is a dairy consultant<br />

with Zentralschweizer Milchproduzenten<br />

(ZMP), the central Swiss milk marketing<br />

concern and a veterinary surgeon.<br />

n Which <strong>cleaning</strong><br />

procedures in particular are<br />

recommended where there<br />

are problems in the milking<br />

operation?<br />

Moist <strong>cleaning</strong> with a disinfection<br />

component reduces the pathogen<br />

pressure from mastitis pathogens or<br />

problem germs in the production of<br />

cheeses (butyric and propionic acid<br />

bacteria, salt-tolerant germs).<br />

contamination, the first step is to carry stimulation for the injection of the<br />

out preliminary <strong>cleaning</strong> (dry paper, milk. Often, however, the same ball<br />

wood wool, udder shower with final is used for several cows, sometimes<br />

drying process). The disinfectant used is<br />

usually chlorine or alcohol. These<br />

components dry quickly, which is<br />

important for the milking process.<br />

Irrespective of the <strong>cleaning</strong> procedure,<br />

the teats should be dry when the milking<br />

cluster is applied Damp teats reduce the<br />

adherence of the rubber liners which then<br />

ride up.<br />

stored for one to two years to<br />

dry. Shredding during the<br />

manufacturing process<br />

guarantees consistent fibre<br />

widths and strengths. The<br />

shredded material finally<br />

passes through sifters and<br />

shakers as well as a suction<br />

device, in order to ensure that<br />

it is for the most part free of<br />

dust and splinters. After a<br />

final sensorical analysis the<br />

wool is compressed and<br />

packaged.<br />

The rapid evaporation of the <strong>cleaning</strong><br />

agent, together. with climatic<br />

influences, can dehydrate the skin<br />

of the teats or leave them scaly and<br />

cracked. In this case a preparation<br />

with good conditioning properties<br />

must be used for teat dipping after<br />

milking; otherwise the system<br />

simply builds in problems. The<br />

container for the moist paper must<br />

be closed after milking, otherwise<br />

the disinfecting agent will evaporate.<br />

Care must be taken when <strong>cleaning</strong><br />

the milking parlour that no dirty<br />

water can get into the container.<br />

n For which types of<br />

dairy farm is agroclean®<br />

udder wool supplied?<br />

High quality wood wool cleans<br />

thoroughly and produces good<br />

e v e n f o r s e v e r a l m i l k i n g s .<br />

Whenever there are already germs<br />

in existence this practice helps<br />

them to spread. When there are no<br />

existing germ problems, in the best<br />

scenario nothing happens for a long<br />

time, until suddenly a pathogen<br />

surfaces. Therefore fresh material<br />

should be used for each cow, which<br />

is true for all procedures.<br />
