INFLUENCE OF AGE ON SOME BLOOD PARAMETERS OF LAMBS IN ORGANIC PRODUCTION

Abstract

The influence of age to changes of some blood parameters was been researched within the blood serum of lambs during the suckling (30th day) and fattening period (70th day). Lamb was holding on the organic way. Significantly decreased concentration of calcium (2.78 and 2.67 mmol/L), inorganic-phosphorus (3.53 and 3.10 mmol/L), triglyceride (0.43 and 0.28 mmol/L), total cholesterol (1.67 and 1.04 mmol/L), HDL and LDL- cholesterol (1.10 and 0.73 mmol/L ; 0.37 and 0.19 mmol/L) as well as increased concentration of sodium (149.43 and 152.14 mmol/L), urea (6.89 and 8.66 mmol/L), total proteins (56.41 and 59.76 g/L), albumins (29.91 and 31.11 g/L) and ALT-alanine aminotransferase activity (9.14 and 12.14 U/L) were determined in the blood of lambs with increasing of age. With increasing age of lamb significantly increased the number of WBC (leucocytes) and RBC (red blood cell) as well as content of haemoglobin and haematocrite in blood. Higher content of platelet and MCV as well as lower content of MCH and MCHC were found in the blood of older lamb in comparison with the youngest lamb. The results of some blood metabolites in the lamb organic production indicate that the age must be taken as a very important factor in determining metabolic profile of blood.
