| Milk mineral matters are important in human nutrition, especially Ca, Mg and I. Increase of milk Mg along decrease of NPK soil fertilization under the Czech Republic (CR) conditions was predicted. This hypothetical prediction is based on antagonistic relationships between K fertilization, Mg level in cow roughage feeding and transfer of Mg into milk. In difference testing the conventional (C) cow milk was reference versus organic (O) milk. Holstein bulk milk samples (BMS) from winter and summer season in 4 C (n = 32 BMSs) and in 4 O (n = 16) herds were investigated. 6 herds were and 2 C were not grazed, other nutrition was typical under the CR conditions. Average MY of C herds was 7016±1068 and MY of O herds was 7037±422 kg per lactation. Macro- and... |

| The full-value experiment is questionable in evaluation organic dairying. It is problem to do a trial under comparable conditions for comparison of organic and conventional farming because of legislative reasons and necessity of long period of such event. Most of comparisons are carried out as practice descriptive observations and any of them has been carried out about milk production. That is main reason, why the aim of this work is to carry out a opening of monitoring of some production conditions and results of bio-dairying in the Czech Republic (CR). The quality aspects of sources, procedures and products are main topics of solution of projects about organic farming philosophy, in particular in solution of organic dairy foodstuff chain.

| Ekologická stáda dojnic v podmínkách České republiky trpí nedostatkem energie ve výživě. To je fakt, vzdor lepší reprodukci a delšímu produkčnímu věku krav v porovnání ke konvenčním chovům. Ekologická stáda také souběžně vykazují příznivě vyšší obsahy Ca a Mg v mléce. Certifikovaná metodika je zaměřena na praktické řešení problému mírného nedostatku dusíkatých látek a nedostatku energie ve výživě krav ve specifických podmínkách ekologického mlékařství. Problém je řešen pomocí vhodných doporučení pro specifickou péči o zakládání a ošetřování travních a jetelovinotravních pastevních a lučních porostů, které tvoří krmnou základnu stád v ekologickém mlékařství. |

| 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).... |
