Abstract
Introduction. In the tropical countries the meteorological
changes exert an effect on the production and
composition of milk, The most important effect is due
to the temperature, precipitation, relative humidity and
solar brightness. Materials and methods. More than
240,000 registers corresponding to the production
and sanitary and composicional quality of the milk of
dairy herds in 2 municipalities of the Department of
Antioquia were collected during 4 years and associated
to the changes in temperature, relative humidity,
solar brightness and precipitation reported by
IDEAM in the same period of time, the statistical analysis
was carried out whit SAS. Results. Was not correlation
between the milk production, percentage of
protein and fat, CSC and bacteriological quality, the
analysis had statistical significance (p < 0,01), was
significant effect of the temperature, the solar brightness,
precipitation on the production parameters and
quality of milk. Discussion. The results found in this
investigation agree in their majority with the presented
by other authors in similar investigations. Conclusions.
Perhaps the parameters of production and
quality of milk are affected by the change in the meteorological
factors the main cause is the effect that
these changes generate on the forage production in
the dairy herds and the additional problems generated
by caloric stress that physiologically undergo
the bovines with these changes.
