| Popis: | The aim of the present research was to determine the blood metabolic profile and acid-base status of Istrian goats in a Mediterranean production system. The research was carried out on 28, non-gravid Istrian goats divided into four groups: group I - ≤ 6 month old kids; group II - ≤ 2 year old goats; group 3 - from 2 to 5 year old goats; group IV - >5 year old goats. The goats were grazing on extensive Mediterranean pastures, but when in the stall, they were fed with hay and approximately 0.2 kg corn per day, as well as water and salt. Haematological parameters were determined in whole blood. The concentrations of biochemical parameters and enzyme activities were determined in the blood serum, while indicators of acid-base balance were determined in the blood plasma. The number of erythrocytes and lymphocytes decreased, while segmented neutrophils and eosinophils increased with age in the Istrian goats. Furthermore, concentrations of Fe, albumin/globulin ratio, cholesterol, triglycerides, LDL-cholesterol, VLDL- cholesterol, inorganic phosphate- and the activity of alkaline phosphatase decreased significantly. An increase was determined in concentrations of urea, total proteins and globulins, as well as the activity of aspartate aminotransferase, weak anions and cations based on total protein calculations. The data obtained on the metabolic profile and acid-base status of Istrian goats are useful for understanding this breed’s parameters, which will help in monitoring health and nutritional status, as well as for improving the management and conservation of this critically endangered breed. Cilj istraživanja bio je utvrditi metabolički profil krvi i acido-bazni status istarskih koza u mediteranskom sustavu proizvodnje. Istraživanje je provedeno na 28 istarskih koza, podijeljenih u četiri skupine: skupina I - jarad dobi do 6 mjeseci; skupina II - koze dobi do 2 godine; skupina 3 - koze dobi od 2 do 5 godina; skupina IV - koze starije od 5 godina. Koze su napasivale ekstenzivne, mediteranske pašnjake, a nakon povratka u staju hranjene su sijenom i s približno 0,2 kg/dan kukuruza, uz vodu i sol koja im je bila na raspolaganju po volji. Hematološki pokazatelji i diferencijalna krva slika određeni su u punoj krvi koza. Koncentracija biokemijskih pokazatelja te aktivnosti enzima određene su u krvnom serumu, dok su pokazatelji acido-baznog statusa određene u plazmi. Broj eritrocita te udio limfocita bio je smanjen, dok se udio segmentiranih neutrofila i eozinofila povećao s dobi istarskih koza. Utvrđeno je znakovito smanjenje koncentracije Fe, omjera albumina i globulina, koncentracije kolesterola, triglicerida, LDL-kolesterola, VLDL-kolesterola, anorganskog fosfora te aktivnosti alkalne fosfataze. Suprotno je utvrđeno u koncentracijama ureje, ukupnih proteina i globulina, kao i aktivnosti aspartat-aminostransferaze te aniona i kationa temeljenih na izračunu iz ukupnih proteina. Dobiveni rezultati o metaboličkom profilu i acido-baznom statusu istarskih koza prve su objavljene referentne vrijednosti koje će pomoći u praćenju zdravstvenog i nutritivnog statusa te u poboljšanju upravljanja i očuvanja ove kritično ugrožene pasmine. |
