Abstract
Republika Hrvatska ima dugogodišnju tradiciju u proizvodnji kozjeg mlijeka. Artritisencefalitis
koza (Caprine arthritis encephalitis, AEK) je virusna neizlječiva bolest koza
prisutna u većini zemalja koje se bave intenzivnom proizvodnjom kozjeg mlijeka. U Hrvatsku
je virus unesen početkom osamdesetih godina prošlog stoljeća kozama iz Francuske.Cilj ovog
rada bio je usporediti količinu i sastav kozjeg mlijeka na tri farme, dvije farme gdje su
životinje bile zaražene virusom i farmom gdje su sva grla bila zdrava. Na sve tri farme
uzgajane su koze pasmine alpina. Držane su u sličnim zoohigijenskim uvjetima te su na sličan
način hranjene. Serološkom pretragom krvi utvrđena je prisutnost virusa AEK na farmi A
gdje su sve životinje bile pozitivne na virus, na farmi B također je postojala prisutnost virusa,
ali se bolest sustavno iskorjenjivala te na farmi C su sva grla bila negativna na virus AEK.
Istraživanje je provedeno u razdoblju od 2012. do 2015. godine. Prema podacima HPA o
ukupnoj količini mlijeka i sastavu mlijeka utvrđena je povećana ukupna količina mlijeka na
sve tri farme te broj somatskih stanica na farmi A i B u odnosu na prosjek. Bolest je potrebno
sustavno iskorijeniti.Republic of Croatia has long tradition in milk goat production. Goat arthritis-encephalitis
(Caprine arthritis encephalitis, CAEV) is viral incurable disease which exists in most
countries that have intense goat dairy production. Virus is imported in Croatia in the last
century (the eighties) with goats from France. The aim of this work was to compare yield and
composition of goat milk on three farms, two farms where goats had CAEV and one where
they didn't have CAEV. All three farms had Alpine breed. Also, they all had similar
zoohygienic conditions and similar diet. Serological examination established CAEV in all
animals on farm A, farm B also had presence of virus, but on less number of animals and farm
C didn't have animals with CAEV. The research was carried out from 2012 till 2015. Data
from Croatian agricultural agency showed increased yield and composition of milk on all
three farms and increased count of somatic cells on farm A and B in comparison to average.
The CAEV needs to be systematically eliminated
