Summary

In a historical sense, current organic farming is an old-new
alternative under changed world conditions. Organic dairying
(O) is an alternative of friendly use of the environment in
time of presupposed global climate changes. Potential impact
of organic farming on raw cow-milk quality, composition and
properties, as conpared to conventional milk production (C),
were evaluatedin this paper on the basis of selectedm ilk indicators
(MIs). Total solids, whey volume, pH of milk fermentation
ability (FAM-pH), FAM streptococci, FAM noble lactic acid
bacteria, I and Cu were higher in C milk (P<0.05). The alcohol stability (AS), titration acidity, curd firmness (CF), FAM titration acidity (FAM-T), Ca, P, Mg, K and Fe were higher in O milk (P<0.05). No differences( P>0.05) were observed in pH, rennet coagulation time, curd quality, FAM lactobacilli and streptococci/lactobacilli, Na, Mn and Zn. In general, the differences were a little more advantageous for O milk from both technological and nutritional point of view, particularly because of AS (0.46<0.58ml , C vs. O) , CF (1.88>1 .81m m), FAM-T (27.3< 33.8ml of 0.25mol . l ' rNaOH. I00ml r )F, AM-pH ( 5.1 > 4.6 ) , Ca (1172 < l257 mg.kg-1)P, ( 950 < l004 mg. kg-1) and Mg 107.4<ll2.0mg.kg{) results. Organic milk can also produce better environment for yoghurt fermentation. Nevertheless, the results obtained should not be overestimated as both sources produced milk of good quality. Additional results are
needed to prove organic milk benefits.
