STUDIES OF INTERVALS BETWEEN MILKINGS IN AUTOMATIC MILKING SYSTEMS
Latvia University of Agriculture, Institute of Agricultural Engineering
The aim of the research – to state how the voluntary milking principle implements milking cows with automatic milking systems (AMS). The research was performed on a farm where two groups of cows are milked by two company “DeLaval” milking robots VMS and for driving the cows to the robots the selective system “feed first” is applied. There were 76 cows in the research group with the average milk yield of the herd 7000 kg/year. The research results showed that milking in robots the programmed milking fre-quencies and the intervals between milking did not materialize. The milking frequency reduces but the intervals between milking increase. The intervals between milking vary in a very wide range and their variations have irregular character. Milking delays in 50% of cases do not exceed two hours, but there are cases that they last for eight hours and more. Analyzing the research results it can be concluded that to ensure a successful milking pro-cess an important role is played by the person who drives the cows that are not milked in the planned time to the robot. The question what influence on the productivity of the ani-mals is left by the variable intervals between milking that often considerably exceed the set values remains open.
