Milking machines milk the cows in the same fashion and rhythm everyday even if the person changes the next day. In Hand Milking when the person changes it affects the cow as the speed of milking of another person will be different and most of the milker’s smoke or chew tobacco while milking.
• Milking machines operate on electricity and its better to choose machines without oil as you need not incur recurring expenses.
• The heart of the milking machine is the Pulsator which helps in pressing the teats of the cow, and it must have alternate pulsation preferably pneumatic oil free type having 60:40 pulsation ratio. It should press opposite teats of the cow like "X". Pressing must be alternate and not all the 4 at a time like you see in some milking machines with piston type pulsators produced in countries from where we get throw away type tape recorders and DVD players.
• The vacuum pump must be preferably oil free type which will help you to avoid recurring expenses having a capacity of 180 litre/minute, connected to an electric motor. It must have a vacuum tank if you need to milk more than 1 cow at a time. Today there are machines which can milk 1/2/5/8/10/12 cows at a time. The motor capacity and the vacuum tank size differ with the number of cows to be milked at a time.
• Irrespective of the number of cows to be milked, you can calculate @ 8-10 cows in one hour & the can capacity will be of 30 litre.
• Hygienic milking: Few steps are to be followed.
1. Wash the udder of the cow first with clean water. Wipe it with a towel.
2. Strip the cows using your hand just to ensure that cows are ready for milk let down.
3. One towel may be used for wiping the teats of the cow. One towel for one cow. Small hand towel. Put it for washing after that
4. Attach the teat cups. You may leave the cow now. It takes 6-8 minutes to milk one cow irrespective of the yield.
5. The milk from the 4 teats of the cow will end in 4 different times. There is no harm in the machine pressing the teats of the cow until you see that milking is over now from the 4 teats of the cow.
6. Once you see that milk is over on all the 4 teats, just press the cluster using your hand just to give a downward pull. See that you don’t press too much. It will give the feeling like how we do normally with our hands when you are about to leave one teat after you finish milking- you press hard on the teat plus a downward pull.
7. Once you complete milking and remove the cluster from the udder ( you will have to remove only one teat cup by inserting your finger between the teat and the rubber liner used for milking the cow. This action will let the air from outside enter the teat cup and it loosens the grip of the teat cup resulting in other teat cups also loosen. You remove only one teat cup and the rest three gets automatically detached, just pull the cluster )
8. Its better to use Iodine spray on the teats after milking. Better than teat dip cups use teat spray or use non returnable dip cups to prevent infection from one teat to another.
9. Make sure you clean the milking cluster using three brushes like Liner Cleaning brush having big bristles at one end and a narrow one at the other end, and a long milk tube brush, a thin brush to clean the milk passage holes inside the teat cup.
10. Cluster assembly will have a top thick plastic and a bottom transparent piece where in you can see milk flowing out from each teat.
11. Use Acid and Alkaline detergents for cleaning, not washing soap or detergent powders as milk will get the smell of soap
