V magistrskem delu smo proučevali koagulacijske sposobnosti mleka (KSM) koz ekološke (EKO) in konvencionalne (KON) reje. Raziskavo smo izvedli na PRC za živinorejo – Logatec s 55 kozami slovenske srnaste pasme. Koze so bile razdeljene v EKO in KON skupino. Koze vsake skupine so bile krmljene z izključno EKO ali KON prirejeno krmo ter krmnimi dodatki. Koze so prav tako imele prost dostop na EKO ali KON pašnik. Tekom štirih vzorčenj mleka smo zbrali tudi podatke o količini prirejenega mleka. Odvzetim vzorcem mleka posamezne živali, smo določili kemijsko sestavo (maščoba, beljakovine in laktoza), število somatskih celic (ŠSC) ter KSM. Količina prirejenega mleka se ni razlikovala glede na način reje, prav tako tudi ne kemijska sestava ter ŠSC. KSM smo ovrednotili s tremi parametri, in sicer s hitrostjo koagulacije (r), hitrostjo nastajanja koaguluma (k20) in čvrstostjo koaguluma (a30). Mleko koz iz EKO skupine je značilno hitreje koaguliralo, medtem ko se ostala dva parametra nista statistično razlikovala. Ker podobnih raziskav v Sloveniji na omenjeno tematiko še ni bilo narejenih, menimo, da so ugotovitve naše raziskave pomembne predvsem za rejce koz, ki mleko predelujejo tudi v sir, da se bodo lažje odločili glede načina reje (EKO ali KON).

Naslov:Coagulation properties of goat milk from organic and conventional farming
Izvleček:
In MSc thesis, we examined coagulation properties of goat milk from organic and conventional farming. The research was taken in the PRC for Animal Husbandry in Logatec with 55 animals of Slovenian Alpine goat breed. Goats were divided into organic and conventional group. Each group was fed exclusively with either organic or conventional adapted fed and feed supplements. Goats also had free access to the organic or conventional pasture, respectively. During four samplings, we collected data about produced milk quantity. Each milk sample, collected from individual animal, was further examined for the chemical composition (fat, proteins, lactose), somatic cell counts and milk coagulation properties. The quantity of produced milk did not differ among farming systems, did neither chemical composition nor average somatic cell counts. Milk coagulation properties were evaluated with three parameters, namely with coagulation rate (r), coagulum formation rate (k20) and coagulum firmness (a30). Goat milk from organic farming significantly faster coagulated, while other two parameters did not differ statistically. Since similar research in Slovenia on this topic has not yet been carried out, we believe that the findings of our research are important for goat breeders, who also process milk into cheese, so that they can decide more easily about the method of farming (EKO or KON).
