BLOOD METABOLIC PROFILE OF TSIGAI SHEEP IN ORGANIC PRODUCTION

Istraživanje metaboličkog profila krvi provedeno je na 15 negravidnih ovaca, cigaja pasmine, u ekološkoj proizvodnji. Koncentracije većine minerala (Ca, P-anorganski, K, Na i Cl) u krvi ukazuju na dobru opskrbljenost ovaca mineralima. Jedino su koncentracije Fe u krvi ovaca (19,10 μmol/L) bile ispod referentnih vrijednosti za ovce, a razlog je vjerojatno manjak ovoga elementa u hrani. Sadržaj glukoze (3,86 mmol/l), kolesterola (1,59 mmol/L) i triglicerida (0,17 mmol/L) u krvnom serumu ovaca ukazuju na zadovoljavajuću opskrbu energijom, a sadržaj ureje (9,80 mmol/l), ukupnih bjelančevina (74,97 g/L) i kreatinina (88,40 μmol/L) na dobru opskrbu bjelančevinama. Aktivnost većine praćenih enzima i koncentracije hematoloških pokazatelja kretala se u granicama referentnih vrijednosti za ovce. Rezultati ovih istraživanja pokazuju da bi obroke ovaca u ekološkoj proizvodnji trebalo obvezno analizirati i uravnotežiti te da se utvrđivanjem metaboličkog profila krvi mogu pravovremeno izbjeći veći proizvodni gubitci uzrokovani neodgovarajućom hranidbom tijekom dužeg vremenskog razdoblja.The investigation on blood metabolic profile was made on 15 nongravid Tsigai sheep in organic production. Concentrations of most mineral (Ca, P-inorganic, K, Na and Cl) in the sheep blood showed adequate mineral supply. Only Fe concentration in the blood of sheep (19.10μmol/L) was below the reference value for the sheep, and the reason was probably lack of this element in food. The average concentrations of blood glucose (3.86 mmol/L), cholesterol (1.59 mmol/L) and triglyceride (0.17 mmol/L) in the sheep confirmed sufficient energy supply. Concentration of urea (9.80 mmol/L), total proteins (74.97 g/L) and creatinine (88.40 μmol/L) in the blood of sheep showed adequate protein supply. Blood enzymes activities and concentrations of hematological indicators ranged within physiological limits for sheep. Research results indicate that meals of sheep in organic production should be analyzed and balanced. The establishment blood metabolic profile higher production losses caused by inadequate nutrition during a prolonged period of time could be avoided
