Sažetak
The aim of the study was to evaluate the results of biochemical profiles of cows from farms with reproductive disorders. The results of blood examinations collected from 205 dairy cows, which originated from 72 Slovenian farms, were analysed. In blood samples total serum protein (TSP), albumin (Alb), urea, calcium (Ca), inorganic phosphate (iP), sodium (Na), potassium (K), chlorine (Cl) and betacarotene concentration were measured. Data were compared with normal reference values for cattle. The results were evaluated regarding the normal values for cattle. The descriptive statistics and percentage of cows deviating from normal values for investigated variables were calculated. The mean values of investigated variables were inside reference intervals for cattle. The results of biochemical examination show deviation from reference interval in 52.3% of cows for TSP, 70.8% for urea, 39.8% for iP, 27.5% for Na, 36.2% for K, 1.1% for Cl, 37.6% for beta carotene and 6.8% for Ca. The results of biochemical investigations revealed the greatest deviations in concentrations of TSP, urea, Na, K and carotene which can be affected by different factors (nutrition, health status, stage of lactation and season). Taking into account all of these factors may be blood biochemistry a useful tool also in identifying deficiencies in the diet.
