Abstract
Introduction. The evaluation of metabolic profiles
(MP) in cattle industries is a useful procedure to value
and apply corrections when necessary and, simultaneously,
is a tool for technicians or herd owners
to monitor the health, and the reproduction. Objective.
To find relationships between MP: cholesterol,
hematocrit, blood urea nitrogen (BUN), milk urea nitrogen
(MUN), proteins, urea, aspartate aminotransferase
(AST), calcium and magnesium, with some
production, health and reproduction parameters.
Methodology. A study was performed on Politécnico
Colombiano Jaime Isaza Cadavid´s dairy herd,
located in a low humid mountain forest. The metabolic
parameters were evaluated throughout a year, by
means of blood samples in 20 cows in peripartum,
during the delivery and after it. Results. The main
metabolic indicators to predict the production were
cholesterol (p<0,042) and urea with (p<0,034), with
statistically significant correlations. As for the herd´s
health, the MPs with a significant correlation were
the calcemia and the hematocrit. The latter can also
be a good indicator of the nutritional condition (related
with the protein levels of the herd). Concerning
the reproductive condition, (open days and conception
services), the body condition and the calcemia had a statistically important relationship to predict
metabolic mismatches. Conclusion. MP evaluation
is recommended because it is an appropriate and
easy to apply tool for technicians and producers in
the monitoring, adjusting and control of production
units, aiming to be successful in the production expected.
