Cilj je ovoga rada utvrditi acidobaznu ravnotežu i vrijednosti hematoloških pokazatelja u krvi visoko gravidnih koza iz ekološkog uzgoja. Istraživanje je provedeno na 10 koza pasmine alpina na ekološkom obiteljskom poljoprivrednom gospodarstvu. Koze su bile u visokom stadiju graviditeta (zadnja 4 tjedna), u dobi od 4 godine i u trećem graviditetu. Hranidba koza bila je smjesom žitarica (50% kukuruz i 50% ječam) i livadnim sijenom po volji. Analizom krvi određeni su sljedeći parametri:pH krvi, plinovi (pCO2, pO2, tCO2) i elektroliti (Na+, K+, Cl- i HCO3-). Od hematoloških pokazatelja krvi utvrđeni su broj leukocita i eritrocita te sadržaj hemoglobina, hematokrita, srednji volumen eritrocita (MCV), prosječan sadržaj hemoglobina u eritrocitima (MCH) i srednja koncentracija hemoglobina u eritrocitima (MCHC). Krvni razmazi su pripremljeni i obojeni po Pappenheimu te je utvrđena diferencijalna krvna slika. Izračunati su anionski procjep (AG), razlika jakih iona (SID) i z vrijednost. Uspoređujući dobivene pokazatelje acidobazne ravnoteže u krvi visokogravidnih koza s referentnim vrijednostima utvrđene su slične vrijednosti većine pokazatelja. Analizom dobivenih hematoloških pokazatelja u gravidnih koza vidljiva su manja odstupanja od referentnih vrijednosti i to viši broj leukocita, MCV i segmentiranih neutrofila, a manji sadržaj hemoglobina te broj eozinofila i monocita. Navedeno ukazuje na manje promjene analiziranih pokazatelja krvi koza u kasnom graviditetu.The aim of this paper is to determine the blood acid-base balance and hematological parameters of high by pregnant goats from organic farming. The research was conducted on 10 Alpine breed goats on are organic family farm. Goats were in a late stage of pregnancy (the last 4 weeks), aged 4 years and in the third pregnancy. Feed a goats were fed with a mixture of cereals (50% corn and 50% barley) and meadow hay ad ibitum. By analyzing the blood pH, gas (pCO2, pO2, tCO2) and electrolytes concentrations (Na+, K+, Cl-and HCO3-) were determined. The number of leukocytes and erythrocytes as well as hemoglobin, hematocrit, mean corpuscular volume (MCV), the average hemoglobin content in erythrocytes (MCH) and the mean hemoglobin concentration in erythrocytes (MCHC) were determined. Blood smears were prepared and colored according to Pappenheim and the differential blood count was determined. In addition, the anion gap (AG), strong ion difference
(SID) and Z value were calculated. Comparing the obtained parameters of acidbase balance in blood of pregnant goats with reference values similar values of most indicators were determined. Analyzing obtained hematological indicators in pregnant goats minor deviation from the reference value, a higher number of WBC, MCV, and segmented neutrophils were apparent, as well as lower hemoglobin content and number of eosinophils and monocytes. This suggests minor changes in goat blood analysed parameters caused by late pregnancy
