Variation of Serum Levels of Glucose and Protein During the Day in Sheep of Different Sex

In order to establish the effect of sampling hour and sex on blood glucose levels and total protein, there were monitored six Colombian native sheep for 3 days. The blood samples were taken by jugular venipuncture, after asepsis and stored at -20°C to its subsequent processing through Spectrophotometry. The results were tabulated in Excel and analyzed using statistical program SAS 9.1. The mean values found were: glucose 75.57 ± 27.5 mg/dL for females and 83.70 ± 37.7 mg/dL for males; total protein 8.47 ± 2.76 g/dL for females and 7.14 ± 3.26 g/dL for males; albumin 4.29 ± 1.41 g/dL for females and 3.83 ± 1.46 g/dL for males; globulin 4.62 ± 2.35 g/dL for females and 3.92 ± 2.45 g/dL for males. The day and the hour of sampling affect serum concentrations (p < 0.05) of evaluated metabolites, also there was variation of themself regarding sex (p < 0.05)
