NOVELTY IN ARRANGEMENT OF OPERATORS WORK AT THE COWS PRE-MILKING TREATMENT

Abstract

Various methods of lactating cows’ udder pre-milking treatment at milking plant of Herringbone type were studied. A perfect variant of operators work arrangement at milking plant of Herringbone type was developed, including pre-milking treatment of cows udder (pre-milking of the first portions of milk, nipples washing and wiping), characterized by the use of a «shuttle» method - the pre-milking of first portions, washing and wiping of udder of the first two cows, then the cluster is connected to the first, and after to the second cows. Advanced operators work arrangement allows to increase the gap between the beginning of pre-milking operations and putting cups on the udder, in comparison with the basic one, up to 38 seconds (2 times more), which promoted to increase of milk yield in the first minute of milking by 0.7 kg/min, reduction of milking time by 0.4 min, reduction of somatic cells count in milk by 65 thousand in 1 ml.
