Sažetak
The aim of the present research was to determine reference values of certain biochemical parameters in blood of 40 Merinolandschaf lambs in organic farming. After weaning lambs were fed with feed mixture and meadow hay of organic origin ad libitum. Average body mass of lambs was 34.01 kg, and average body condition score was 3.86. Within blood serum the concentrations of mineral parameters (calcium, phosphorus-inorganic, magnesium and iron), concentrations of the biochemical parameters (urea, glucose, total proteins, albumin, cholesterol, HDL-cholesterol ; LDL-cholesterol, triglyceride, BHBA-β- hydroxibutyrate and NEFA-non-esterified fatty acids) and enzyme activity (CK-creatine kinase, ALP-alkaline phosphatase) were examined. Most of the biochemical parameters´ concentrations in the lambs´ blood was within reference values for lambs, except albumin (28.05 g/L), Ca and Mg (2.43 and 0.90 mmol/L) concentrations as well as activity of CK enzyme (170.49 U/L) which was bellow or on the lower reference values as well as concentration of globulins (30.02 g/L) which was higher compared to reference values. Determined changes of biochemical parameters in the blood of Merinolandschaf lambs in organic farming indicated the need for redefinition of these parameters as reference values and presents adequate supply of lambs with nutrients through diets. Determined biochemical parameters in the blood of Merinolandschaf lambs in organic production can be used as reliable criteria in assessment of nutrients supply through diets, as well as redefinition of reference values´ limits of these parameters in the blood, as well as their reference values.
