Economic profitability of milk production.

摘要

Three different kinds of technological versions of milk production have been compared: when cows are tied in warmed barns and milked in the milk line, when cows are kept in cold barns and milked in the milking parlour and when cows are handled loose in cold barns and milked in milking robots. The versions have been compared according to the obtained milk production cost applying a special mathematical model designed for this purpose. It has been stated that handling of cows in cold barns and milking in a separate milking parlour have turned out to be the most efficient milk production technologies. Nevertheless, it is possible to reduce the milk production cost also increasing the milk yield and the size of the herd. If, for instance, the milking robots VMS produced by the company „DeLaval” and corresponding to them milk production technologies are applied, then at the milk yield 10000 kg year -1 the milk production cost is 0.16-0.17 Ls kg -1 , but at the milk yield 8000 kg year -1 it is 0.17-0.19 Ls kg -1 .
