To evaluate existent relationship among production of adjusted milk to 244 and 305 days of nursing in cows Siboney de Cuba and some reproductive and not reproductive factors during 5 serial years, information related with nursing's was compiled finished in period 2010-2015, of 214 cows of the unit «LaJíbara». Conformed to database that facilitated to analyze production of milk in both nursing's according to: I weigh incorporation to reproduction, age to the first childbirth, interval childbirthchildbirth, time of the year to the childbirth, as well as incidence of the
empty days on production of milk. To the no reproductive factors in study was carried out variance analysis according to model of simple classification, by means
of docima of comparison of stockings LSD Fisher, while to the reproductive ones, was carried out non parametric
variance analysis of simple classification Kruskal Wallis, by means of docima of Conover. You concludes when evaluating the effect of factors associated to the
production of milk that the incorporate females to the reproduction should count approximately of 300 Kg of weight I live and appropriate age, aspect that demands
to work more with the substitution from early ages, to reach a first childbirth around 32 months of age, what is reached when combining existent alimentary technologies appropriately in the tropic, with correct handling of the same ones, should also improve it disciplines technological of the reproductive handling of the flock that allows to serve and to gestate the biggest quantity in cows in the period postchildbirth, that which improves
the production of milk and the general economy of the exploitation substantially.
