BUSTAMANTE, Moris de J et al. Determination of Metabolic Profile During The Gestation-Lactation in Ewes Hair in Cordoba, Colombia. Rev. Fac. Cienc. Vet. [online]. 2016, vol.57, n.2, pp.114-124. ISSN 0258-6576.
The 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.
