RESEARCH ON EFFECT OF MILKINGS FREQUENCY ON COWS' MILK PRODUCTION.

In the present socio-economic context and environmental sustainability trend it is a high accent on milk production related with increased milk yield per cow. This study aims to explore the influence of milking technology for Holstein dairy cows on "milk" productivity and quality, at the farm level. Over three consecutive years, the dynamics of milk quantity and its quality parameters (% fat, % protein, somatic cells count, % dry matter) were followed. The values of these parameters changed as a result of the increase of milkings frequency per day, from two in the first year of study, to three milkings per day in the following years. The results were statistically analyzed, from the point of view of significance, using the Fisher and Student tests. The comparative analysis of the 3 years of production shows that milk production had a positive evolution, both in terms of quantity and quality. [ABSTRACT FROM AUTHOR]
