Abstrakt: Limited research has characterized blood chemistry in healthy stock-type foals. Our objectives were to determine foal serum chemistry and hematology changes during the first 72 hours postnatal and compare these with adult horse reference ranges. Over 3 foaling seasons, serum chemistry and hematology were determined for 16 healthy stock-type foals born to similarly managed mares. Blood was collected at 0 hours (before nursing but after standing, within 85 minutes of birth) and 6, 12, 24, 48, and 72 hours after initial sampling. Data were analyzed with sampling hour, year, and their interaction as fixed effects. Serum glucose and triglyceride concentrations increased (P < .001) from 0 to 24 hours. Triglycerides increased (P < .001) and glucose decreased (P = .01) between 24 to 48 hours. Serum nonesterified fatty acids increased (P = .04) from 0 to 6 hours and decreased (P ≤ .01) from 6 to 24 hours. Serum urea nitrogen increased (P < .001) between 0 and 6 hours and decreased (P < .001) from 12 to 72 hours. Serum total protein and globulin concentrations increased (P < .001) from 0 to 12 hours, albumin decreased (P ≤ .01) from 0 to 24, and creatinine decreased (P ≤ .02) from 0 to 72 hours. Hour also affected (P ≤ .03) electrolytes, metabolic enzymes, and all hematological components except for mean corpuscular hemoglobin (P = .77). These data demonstrate dynamic blood biochemical and hematological changes throughout the first 72 hours in foals, suggesting that sampling time should be considered when evaluating individual neonates.
