Abstract


The aim of the paper was to characterize the raw milk collected in the Western partof Romania by a milk processing company, both chemically and hygienically.Researches were carried out on 3988 milk samples collected from a severalcollecting points and dairy farms from Timiş, Arad and Caraş-Severin counties.Monthly, two samples were collected at least from each farm or collecting point.Chemical composition and somatic cell count (SCC) were determined on eachsample. In Timiş and Arad counties the milk was significantly lower in total solidsthan in Caraş-Severin County (12.6% vs. 13.2%), but somatic cell count was higher,exceeding the higher limits admitted by the norms. Season had a significantinfluence on both chemical composition and SCC. While the total solids content ofthe milk was lower during the summer and autumn the SCC was higher in the sameseasons. Chemical composition gets better from year to year, except for the milk fatpercentage that was similar throughout the study period. It was concluded that therea major influences of county, season and year of collection on the chemicalcomposition and SCC, with direct influences of the breed structure and type of thefarm that produces the milk.
