Abstract:
Having in view that, Brown breed have an important rate in cattle breed structure from Vrancea
County, we consider that it is opportune to carry out a study concerning the seasonal variation of
qualitative features of raw milk obtained from this breed, due to specific technologies and
technological factors management applied in the area.
The results of this research aim to complete the information regarding quality of raw milk
gathered from Brown breed cattle which are registered in Vrancea County Official Control of
productive performances. Research was carried out to determine the raw milk quality by specific
physical-chemical and microbiological analysis, for parameters such as: somatic cell count, dry
matter, fat, protein, lactose and casein content, urea, density and pH.
The mean values and variability estimators for somatic cell count ranged between 242600
(winter) and 573200 (summer), dry matter oscillated between 11.84% and 13.42%, the fat
percentage varied between 3.28% (spring) and 4.34% (winter), protein percentage recorded mean
values between 3.21% and 3.96% in autumn, respectively in winter; lactose content was between
3.78% and 4.87%, casein content ranged between 27.46 g/l and 29.29 g/l.
