Abstract
    In the current paper we aimed to establish the quality of integral raw milk gathered from Fleckvieh cows breed, through physical-chemical and biochemical analysis. The obtained results, at the end of determinations, were compared with the values indicated in ASRO Romanian Standard, SR 2418:2008 for integral raw milk and with the ones presented in the Guide for rearing of Fleckvieh cows breed.
    For establishing the quality we effectuated physical-chemical determinations for fat content the (%), protein titre (%), lactose (%), DM (%), NFDM (%), water content (%), ash (%), density (g/cm³), acidity (°T) and biochemical were made the reductase probe, methylene blue and resasurin method.
    For fat content the established mean value was 4.24±0.064% with 0.44% higher than the indicated value in the breed rearing guide. Regarding protein titre, standard allows a minimum value of 3.2%, rearing guide 3.29% and the value obtained by us was placed at a level of 3.35±0.008%. For lactose the obtained mean was 4.83±0.011% and regarding the content in NFDM was obtained a mean of 8.84±0.020%.
    Generally we can say that milk obtained from Fleckvieh cows breed, reared at Rediu Farm, was in according with the nowadays quality standards.
