| description | High numbers of bovine breeds have been selected as milk producers, but those derived from the Bos taurus breeds have been unable to adapt to tropical conditions. The aim of this work was to analyze the metabolic profile of the seven breeds (Ayrshire, Girolando, Holstein Friesian, Jersey, Lucerna, Brown Swiss and Simmental) through the use of 15 metabolites. For each breed, 28 animals were used, divided into four physiological different groups: heifers, cows from the first stages and last stages of the lactation process and dry cows. The mean values of metabolites indicators were as follow: BOH 0.5 mmol/l; glucose 2.8 mmol/l; cholesterol 2.5 mmol/l; potassium 4.1 mmol/l; calcium 2.0 mmol/l; inorganic phosphorus 1.7 mmol/l; magnesium 1.1 mmol/l; total protein 66.2 mg/dl; albumin 25.8 mg/dl; globulin 40.2 mg/dl; creatinine 109 µmol/l; BUN 3.8 mmol/l; ALT 32.2 UI/l; AST 56.6 UI/l; GGT 12.3 UI/l; total bilirubin 0.2 µmol/L; conjugate bilirubin Additionally, body condition and PCV were determined with average values of 3.25 and 27% respectively. A significant statistical difference was found among breeding groups and physiological groups for production. It was observed that those animals with a low metabolic weight (Jersey) demonstrate better homeostasis than those of high metabolic weight (Simmental, Holstein).<br>Se ha seleccionado un alto número de razas bovinas para producción de leche, sin embargo, las de origen Bos taurus no han logrado adaptarse a las condiciones tropicales. El objetivo del trabajo fue analizar el comportamiento metabólico de siete razas (Ayrshire, Girolando, Holstein Friesian, Jersey, Lucerna, Pardo Suizo y Simenthal) a través de 15 metabolitos. Se emplearon 28 animales por raza, distribuidos en cuatro grupos fisiológicos: novillas, inicio y final de lactancia y vacas secas (final de gestación). Los valores medios de los indicadores metabólicos fueron: BOH 0.5 mmol/l; glucosa 2.8 mmol/l; colesterol 2.5 mmol/l; potasio 4.1 mmol/l; calcio 2.0 mmol/l; fósforo inorgánico 1.7 mmol/l; magnesio 1.1 mmol/l; proteínas totales 66.2 mg/dl; albúmina 25.8 mg/dl; globulinas 40.2 mg/dl; creatinina 109 µmol/l; BUN 3.8 mmol/l; ALT 32.2 UI/l; AST 56.6 UI/l; GGT 12.3 UI/l; bilirrubina total 0.2 µmol/l; bilirrubina conjugada 0.08 µmol/l. Los valores medios de la condición corporal y el hematocrito fueron 3.25% y 27.0% respectivamente. Se encontraron diferencias estadísticas significativas entre grupos raciales y entre grupos de producción. Los animales de menor peso metabólico (Jersey) presentaron mejor homeostasis que los de pesos mayores (Simenthal, Holstein). |
