Abstract

Svrha istraživanja bila je utvrditi postoje li razlike kemijske i mikrobiološke kvalitete sirovog mlijeka sa 30 farmi različitih veličina iz istočne, središnje i južne hrvatske regije. Dobiveni rezultati uspoređivani su sa službenim podacima Hrvatske poljoprivredne agencije za 2008. godinu te kriterijima kvalitete propisanim Pravilnikom o kakvoći svježeg sirovog mlijeka. Utvrđeni rezultati kemijske kvalitete mlijeka - udjela mliječne masti i bjelančevina u potpunosti za sve skupine malih i velikih gospodarstava iz istočne, središnje i južne regije udovoljavaju uvjetima propisanim Pravilnikom o kakvoći svježeg sirovog mlijeka iz 2000. godine. Promatrajući vrijednosti ukupnog broja mikroorganizama, jedino skupina malih gospodarstava južne regije ne udovoljava uvjete propisane Pravilnikom o kakvoći svježeg sirovog mlijeka iz 2000. godine. Utvrđena je statistički značajna razlika (P<0,01) između broja somatskih stanica (BSS) u mlijeku velikih gospodarstava sve tri regije, dok između BSS u mlijeku malih gospodarstava različitih regija nije utvrđena statistički značajna razlika.

Abstract (english)

The purpose of this study was to determine whether there are differences between chemical and microbiological quality of raw milk from 30 farms of different sizes from eastern, central and southern Croatian regions. The results were compared with official data of the Croatian Agricultural Agency for 2008 and with the quality criteria prescribed in the Regulations on the Quality of Fresh Raw Milk. The results of chemical quality of milk - of milk fat and protein entirely, for all groups of large and small farms in eastern, central and southern regions meet the requirements of the Regulations on the Quality of Fresh Raw Milk in 2000. Looking at the value of the total number of microorganisms, only a group of small agricultural holdings of the southern region do not meet the requirements prescribed by the Regulations on the Quality of Fresh Raw Milk in 2000. There was a statistically significant difference (P<0.01) between somatic cell count (SCC) in milk of large agricultural holdings of all three regions, while the SCC in milk of small agricultural holdings of different regions did not show a statistically significant difference.
