For Those who have not seen or experienced a milking machine, may do the following steps in order to understand the working of the machine.
Please insert your finger inside the cluster used for milking cows in the milking can. It will only press and leave, press and leave your finger, exactly like how you milk a cow using your hand. Here the rhythm is the key. See for example, today you are relaxed, have time, you milk slowly. Tomorrow there must be some marriages, you are in a hurry. You need to go early. So you do milking faster. That means, the same person milking in 2 days will be in different fashion.
You cannot create damage to the cows teats even if you keep the cluster there ( in the udder of the cow) for long because of the pressure induced, which is measured using a vacuum gauge and a vacuum regulator. These comments were spread by the villagers in the 1980’s when milking machines were launched and getting popular in India. Now a days even illiterate people won’t have these doubts as machines have become common everywhere. No fears that the machine will injure the cow’s teats. Remember to buy machines without oil lubrication as in oil based machines vacuum pump gets choked fast when dust from the atmosphere gets mixed with oil and ensuring the farmer recurring expenses every month. Try to keep machines where dust is minimal. Remember that the pulsator is the heart of the machine and it must have alternate pulsation and not all 4 teats at a time which is not correct,preferably pneumatic type,oil free.
MILKING IS A TEAM EFFORT BETWEEN THE COW, THE MACHINE, THE OPERATOR AND THE CALF A SILENT PARTNER IN THE ENTIRE EPISODE.
