Sažetak
Cika cattle are an indigenous breed in Slovenia, while the Simmental breed is a cosmopolitan breed. The fattening trial was prepared to investigate whether Cika bulls are suitable for beef production, and the Simmental bulls were kept for comparison. The aim of this study was to investigate if different feeding technologies affect the haematological parameters of Cika and Simmental bulls. Blood samples of 17 Cika and 19 Simmental young bulls were taken in tubes with EDTA. The number of erythrocytes (RBC), leucocytes (WBC) and platelets (PLT), and the values of haemoglobin (Hb), haematocrit (PCV), the mean corpuscular haemoglobin (MCH), the mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) were measured with a
haematological analyser ABC Vet. Differential white blood cells counts were also prepared. Data were analysed by the GLM procedure from the statistical package SAS/STAT regarding the breed, feeding technology and their interaction as fixed effects. In the blood of Cika bulls there was a significantly higher number of leucocytes as well as haemoglobin, haematocrit, MCV and MCH values than in the blood of Simmental bulls, while the number of platelets was higher in the blood of Simmental bulls. Different feeding technologies signifi cantly affected the erythrocyte count, and MCV and MCH values, where pasture reared bulls had lower erythrocyte and higher MCV and MCH values compared to stable fattened bulls. In the differential white blood cell count of Cika bulls there was a significantly higher percentage of segmented neutrophils and a lower percentage of lymphocytes compared to Simmental bulls.
