Abstract
was highly correlated with indicators of productive importance, such as productivity per cow, production of milk/ha and total production per semester. Only this component was highly correlated with time and with the main technological changes, like paddocking and the percentage increase of Cuba CT-115 pasture. However, the relation was low with the sugarcane percentage and that of artificial pastures, replacement percentage of animals, stocking and birth. These indicators were not highly modified in time. The rotated matrices were used
to determine the impact indexes in each scene, which changed their values, from negative to positive, with the years, and were, at the same time, an impact demonstration of this technology. The relation MC 1 allowed reliable regression equations in time, expressing the impact
values of the biomass banks on the main productive indicators. Under the conditions of this BUCP, the organizational actions increased the milk production in 60 L/ha/year. The interval parturition-gestation decreased in 6.5 d/year. The milk/lactation increased in 73.3 L/year,
the total milk production per dairy unit in 6252 L, and the liter per milking cow in 0.2/year. It is suggested that the BUCP considers a new cycle of developing the technologies and methods of animal management to increase the stocking rate, amount and quality of the feed for the dry season and favor the diminishing of the interval parturition-gestation.
Key words: milk production, technological impact, multivariant designs.
