espanolEl objetivo de este trabajo fue determinar el perfil metabolico durante el periodo gestacion-lactancia en hembras ovinas de pelo, manejadas en pastoreo en Cordoba, Colombia. Se tomaron muestras de sangre de 56 hembras ovinas en el ultimo tercio de gestacion y durante 90 d de lactancia, de fincas ovinas localizadas en tres subregiones del departamento de Cordoba, Colombia. Se determinaron las concentraciones en sangre de glucosa, trigliceridos, colesterol, β-hidroxibutirato (β-h), proteinas totales, albumina, globulina, urea, calcio (Ca), fosforo (P) y magnesio (Mg). La informacion fue analizada a traves un analisis de varianza para determinar diferencias significativas (p≤0,05) entre periodos y la prueba de Tukey para la comparacion de medias, para ello se utilizo el paquete estadistico SAS. Los valores medios encontrados fueron 62,24 ± 11,76 mg/dL para glucosa, 47,27 ± 24,62 mg/dL para trigliceridos, 84,80 ± 59,09 mg/dL para colesterol, 0,02±0,03 mg/dL para β-h, 5,82 ± 1,07 g/dL para proteinas totales, 2,21 ± 0,61 g/dL para albumina, 3,64±1,13 g/dL para globulinas, 32,50±15,85 mg/dL para urea, 11,37± 2,34 mg/dL para Ca, 5,95±2,31 mg/dL para P y 2,28±0,45 mg/dL para Mg. Se presentaron diferencias estadisticas entre fincas y periodos estudiados, con una disminucion de las medias de las variables estudiadas a medida que se aproximaba el parto, y una recuperacion de las concentraciones adecuadas al finalizar la lactancia, dejando ver la necesidad de complementar la alimentacion suministrada con una adecuada suplementacion energetica, proteica y mineral, durante el ultimo tercio de la gestacion y los primeros 60 d de lactancia. EnglishThe aim of the present investigation was to determine the metabolic profile of female haired ewes under grazing management, during the gestation-lactation period, in the Department of Cordoba, Colombia. Blood samples of 56 haired ewes were taken in the last third of gestation and during 90 days of lactation at sheep farms located in three sub-regions of the Department of Cordoba. Blood concentrations of glucose, triglycerides, cholesterol, β-hydroxybutyrate, total proteins, albumin, globulin, urea, calcium (Ca), phosphorus (P), and magnesium (Mg) were determined. The information was analyzed through an ANAVAR to determine the existence of statistically significant differences (P≤0.05) between periods; and by aTukey test for comparison of means, for which the SAS statistical software was used. The mean values for the metabolic variables found were: 62.24 ± 11.76 mg/dL for glucose; 47.27 ± 24.62 mg/dL for triglycerides; 84.80 ± 59.09 mg/dL for cholesterol; 0.02 ± 0.03 mg/dL for β-hydroxybutyrate; 5.82 ± 1.07 g/dL for total proteins; 2.21 ± 0.61 g/dL for albumin; 3.64 ± 1.13 g/dL for globulins; 32.50 ± 15.85 mg/dL for urea; 11.37±2.34 mg/dL for Ca; 5.95±2.31 mg/ dL for P; and 2.28±0.45 mg/dL for Mg. Statistical differences between farms and periods studied were found, with a decrease in the means of the variables under study, as calving approached, and a recovery of the appropriate concentrations at the end of lactation, pointed to the need of supplementing the primary food with adequate amounts of energy, proteins and minerals, during the last third of gestation and the first 60 days of lactation.
