Abstract
S obzirom na sve intenzivniji porast proizvodnje kozjeg mlijeka, velika pozornost se pridaje ukupnoj kvaliteti, koja podrazumijeva i higijensku kvalitetu mlijeka procijenjenu na osnovu broja somatskih stanica. Cilj rada bio je opisati čimbenike koji utječu na povećani broj somatskih stanica, te njihov utjecaj na kvalitetu kozjeg mlijeka i sira. U koza broj somatskih stanica nije definiran zbog apokrinog načina sekrecije mlijeka. Najvažniji infektivni čimbenici povećanog broja somatskih stanica su patogene bakterije iz roda Staphylococcus. Neinfektivni čimbenici koji utječu na broj somatskih stanica u mliječnih koza su: stadij i redoslijed laktacije, dob, pasmina, estrus, partus te sezonske varijacije. Većina autora predlaže kao gornju graničnu vrijednost broja somatskih stanica 1x106/mL, dok prema pojedinim autorima tek broj iznad 1,5x106/mL ukazuje na negativne promjene u vimenu životinje. Povećani broj somatskih stanica u mlijeku koza utječe na promjene fizikalno-kemijskog sastava i preradbenih svojstava mlijeka. U konačnici preradbena svojstva kozjeg mlijeka utječu i na kvalitetu sira.
Abstract (english)
Because of intensive growth of goat's milk production, great attention is given to total quality, which also implies the hygienic quality of milk estimated on the basis of the number of somatic cells. The aim of the study was to describe the factors affecting the increased number of somatic cells and their impact on the quality of goat 's milk and cheese. The number of somatic cells in the goat milk is not defined because of the apocrine way of milk secretion. The most important infectious factors of the increased number of somatic cells are pathogenic bacteria Staphylococcus spp. Noninfective factors affecting the number of somatic cells in dairy goats are: stage and number of lactation, age, breed, estrus, partus and seasonal variation. Most authors suggest the upper limit value of somatic cell count of 1x106/mL, whereas for individual authors only a figure above 1.5x106/mL indicates negative changes in udder of the animal. An increased number of somatic cells in goat's milk affects the changes in the physico-chemical composition and processing properties of milk. Ultimately, the processing properties of goat milk are also affecting on the quality of cheese.
