BIOKEMIJSKI I HEMATOLOŠKI POKAZATELJI I INDEKS TJELESNE KONDICIJE KRAVA HOLSTEINSKE PASMINE S OBZIROM NA OCJENU DOBROBITI

Animal welfare (AW) is a term denoting how the animals are coping with the conditions in which they live. A precise welfare assessment assumes a multidisciplinary approach, and modern evaluation protocol incorporates both the animal-based and non-animal-based measures. Due to the different welfare score classes, this study’s objective was to determine the variability of biochemical and hematological parameters, as well as the body condition score. The study was conducted involving 145 Holstein cows, randomly chosen from the six commercial dairy cow farms. The dairy cows’ welfare assessment checklist consisted of seventy items, pursuant to the CReNBA protocol. The biochemical parameters in blood and the milk plasma were determined using the Beckman Coulter AU400 (Beckman Coulter, FRG) automatic clinical chemistry analyzer. The obtained results indicate that the lower albumin, triglyceride, iron, and calcium values were detected in the cows bred on the farms that were ranked lower concerning the farm management and farm infrastructure levels. In the milk plasma, the concentration of albumins was higher (P<0.05) on the farms that were ranked lower concerning the farm management, infrastructure level, and total score scale. Iron concentration was higher (P<0.05) in the cows from the farms ranked lower concerning farm infrastructure and on the farms that were ranked higher concerning the animal level. The erythrocyte sedimentation rate was higher on the farms with worse marks on the farm infrastructure level and total AW score.Dobrobit životinja predstavlja procjenu stanja životinja kojima reagiraju na podražaje iz okoline. Precizna procjena dobrobiti podrazumijeva multidisciplinaran pristup, a suvremen evaluacijski protokol uključuje mjerenja na životinjama i mjerenja koja uključuju smještaj, hranidbu i upravljanje farmom. Svrha ovoga istraživanja bila je odrediti varijabilnost biokemijskih i hematoloških pokazatelja, kao i tjelesnu kondiciju, s obzirom na različite bodovne razrede dobrobiti. Istraživanje je provedeno na 145 krava holsteinske pasmine, nasumično odabranih na šest komercijalnih farma mliječnih krava. Kontrolni popis procjene dobrobiti mliječnih krava sastojao se od 70 pitanja prema protokolu CReNBA. Biokemijski pokazatelji u krvi i mliječnoj plazmi određeni su automatskim kemijskim analizatorom Beckman Coulter AU400 (Beckman Coulter, SRNj). Dobiveni rezultati ukazuju da niže koncentracije albumina, triglicerida, željeza i kalcija u krvi imaju krave na lošije ocijenjenim farmama s obzirom na menadžment farme i infrastrukturu. S obzirom na pokazatelje infrastrukturnih karakteristika farme, menađmenta i ukupnu ocjenu farme, koncentracija albumina u mliječnom serumu bila je veća (P
