Sažetak

The aim of the present research was to determine the blood metabolic profile and acid-base balance of dairy goats and of their kids during lactation. Analyses were made of 15 Alpine goats and their suckling kids, in a traditional production system. The goats’ blood was collected from the 20th to the 140th day of lactation every 30th day. Kids´ blood was collected on the 20th and 50th days of life. From the blood samples the values of pH, partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), total pressure of carbon dioxide (tCO2) and bicarbonate (HCO3-) were determined. Afterwards, the blood samples collected from the goats and kids were centrifuged, and from the plasma obtained the concentrations of calcium, phosphorus-inorganic, potassium, sodium, iron, chloride, urea, glucose, total proteins, albumin, creatinine, cholesterol, HDL-cholesterol, LDL-cholesterol, trygliceryds, alkaline phosphatase (ALP), creatine kinase (CK) and γ-glutamyl transferase (GGT) were assessed. Also, the strong ion difference (SID), anion gap (AG) and z-values were determined from the blood of the goats and kids. The results were obtained by MEANS procedure, and differences between the groups were determined using ANOVA repeated measures. A significant decrease in glucose, tryglicerides, Na and Fe concentrations was determined, as well as the AG and SID content in the blood, and increases in cholesterol, HDL-cholesterol, LDL-cholesterol, total protein, albumin, globulin and P-inorganic in the blood of goats during lactation. The concentrations of Cl, creatinine, and enzymatic activity (CK, GGT and ALP) in the blood of goats during lactation did not differ significantly. The results of the blood metabolic profile and acid-base balance indicate the need for better control of goats and kids´ rations in traditional production systems.
