Desequilibrios metabólicos con especial referencia a las carenciales de minerales asociadas a problemas reproductivos en vacas lecheras de Cuba
2011
The objective of this study was to diagnose the principal metabolic
imbalances and deficiencies associated with reproductive disorders
especially due to mineral deficiency in crossbreed (Holstein × Cebu) dairy
cows under restrained system of production in the central region of Cuba.
The study was conducted in a dairy herd with deteriorated principal
reproductive efficiency indicators, 50 animals were selected, metabolic
minerals, proteins and hemogasometric parameters were evaluated.
Descriptive statistic, data distribution type, range reference and the
proportion of animals with normal values, suspected or pathologic for all
variables were calculated. For the study of the principal factors that
determine reproductive alterations in the herd, principal component
analyses were calculated. In the animals diagnosed, 68 and 56% had Cu
and P deficiencies and the state of hypoproteinemia and
hypomagnesaemia were also found in the same order respectively.
