The necessity of creation of the optimal conditions for production of high-quality dairy products was conditional upon the fact that milk is very unstable by its chemical and physical indicators biological liquid. There is no point in improving milk quality after the realized production. Results of the realized in the conditions of the Republic of Belarus evaluation of milk according to the sanitary and hygienic indices for the further improvement of its quality were presented. According to the data on milk purchasing it noted that in Belarus there was stated a noticeable reduction of milk quality in accordance with its grade of quality. Throughout the last years the relative density of realization of the premium quality milk was less than 50% (46,5% - in 2005, 48% - in 2006), and at the same time, the volume of sales of the second second-rate quality milk reduced on 7,6%, and volume of off-grade milk - on 0,7%. Milk quality at the studied in course of investigation dairy farms in the majority of cases was conditional upon such indicators as base-titratable acidity, bacterial number and quantity of somatic cells in milk. Titrate acidity indices in over than 36% of milk does not correspond in to standards of the Republic of Belarus. Evaluation of bacterial number in the produced milk showed that its main production volume (65,2%) corresponded to the first and second grades and 6,7% were off-grade quality. Somatic cells content in the studied milk samples in 27% corresponded to the extra fine grade, and only about 2% of the analysed milk samples corresponded to off-grade milk

Results of estimation of the real possibilities of milk production of extra fine grade in the conditions of the Republican unitary enterprise Educational Farm of Belarus State Academy of Agriculture in Mogilev region (Republic of Belarus) were presented. It was established, that carrying out of some organizational and technological actions for decreasing the level of somatic cells in milk made it possible to lower the level of somatic cells in finished products from 494,72 thousand per cube cm up to 289,15 thousand per cube cm. The obtained data corresponded to requirements of the Standard of the Republic of Belarus (STB 1598 - 2006 Cow milk. Requirements at purchases to the grade milk Extra). The realized experiment was developed on the basis of analytical model of cow commercial herd, constructed on the basis of the analysis of results of evaluation of quality of individual tests. Sales level of extra fine grade milk at the dairy commodity complex Parsino (Republic of Belarus) was 90,6%
