Abstract
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.Cika je autohtona pasmina goveda u Sloveniji, dok je simentalska rasprostranjena diljem svijeta. Tijekom istraživanja, organiziran je pokusni tov kako bi se utvrdila prikladnost bikova pasmine cika za proizvodnju junećeg mesa. Bikovi simentalske pasmine poslužili su za usporedbu. Cilj je bio istražiti je li različite tehnologije hranidbe utječu na hematološke pokazatelje kod bikova cika i simentalske pasmine. Uzorci krvi od 17 cika i 19 simentalskih bikova prikupljeni su u epruvete uz dodatak EDTA. Uz pomoć ABC Vet. analizatora utvrđen je broj eritrocita, leukocita, trombocita, te vrijednosti hemoglobina, hematokrita (engl. PCV), prosječni sadržaj hemoglobina u eritrocitima (engl. MCH), prosječna koncentracija hemoglobina po eritrocitu (engl. MCHC) i prosječni obujam eritrocita (engl. MCV). Također su utvrđene i razlike u tipu i broju leukocita. Podatci su analizirani pomoću GLM postupka statističkog programa SAS/STAT uz uvažavanje pasmine, tehnologije hranidbe i njihove interakcije kao fiksnih učinaka. U krvi bikova pasmine cika ustanovljen je signifikantno veći broj leukocita te veće vrijednosti za hemoglobin, hematokrit, MCV i MCH u odnosu na krv bikova simentalske pasmine. Istovremeno, broj trombocita bio je veći u krvi bikova simentalske pasmine. Različite tehnologije hranidbe signifikantno su utjecale na broj eritrocita, te vrijednosti MCV i MCH, pri čemu su pašno uzgojeni bikovi u odnosu na bikove uzgojene u staji imali manji broj eritrocita i veće vrijednosti MCV odnosno MCH. Razlike u tipu i broju leukocita pokazale su da bikovi pasmine cika, u usporebi s bikovima simentalske pasmine, imaju signifikantno veći postotak segmentiranih neutrofila i manji postotak limfocita
