Description
| - Original paper presents the comparison of mineral milk composition of goats (White short–haired–W, n = 60), sheep (Tsigai–C, n = 60) and cows (Holstein–H, n = 36; Czech Fleckvieh–B, n = 93, bulk milk samples). Goat milk freezing point differed from other species (P < 0.001), –0.6048 for C < –0.5544 W < –0.5320 H < –0.5221 °C for B. Cow milk Ca values were comparable to former results although milk yield (MY) was higher. Along lower MY the Ca was higher (1299.6 > 1172.0 mg.kg-1; P < 0.001) in B than H, similar trend was in Mg (122.0 > 107.4 mg.kg-1; P<0.001). Differences (P > 0.05) between species were in Ni and also mostly in Cu. Iodine results differed between species but not between cow breeds (P < 0.001; 462.8 H and 434.9 B > 126.0 W and 164.2 μg.l-1 C). Macroelements were mostly highest (Ca, P, Na, Mg) in sheep milk, with exception of K. Phosphorus values (950.1 H, 1016.9 B, 1042.6 W and 1596.7 mg.kg-1 C) in species were linked with crude or true protein and casein values.

- Původní práce uvádí srovnání minerálního složení mléka koz (bílá krátkosrstá–W, n = 60), ovcí (cigája–C, n = 60) a krav (holštýn–H, n = 36; český strakatý skot–B, n = 93, bazénové vzorky mléka). Bod mrznutí kozího mléka se lišil od ostatních druhů (P < 0,001), –0,6048 pro C < –0,5544 W < –0,5320 H < –0,5221 °C pro B. Hodnoty Ca kravského mléka byly srovnatelné k dřívějším výsledkům, ačkoliv mléčná užitkovost (MY) byla vyšší. S nižší MY byl Ca vyšší (1299,6 > 1172,0 mg.kg-1; P < 0,001) u B než H, podobný trend byl v Mg (122,0 > 107,4 mg.kg-1; P < 0,001). Mezidruhové rozdíly (P > 0,05) byly u Ni a také většinou u Cu. Výsledky I se lišily mezi druhy, ale ne mezi plemeny krav (P < 0,001; 462,8 H a 434,9 B > 126,0 W a 164,2 μg.l-1 C). Makroprvky byly většinou nejvyšší (Ca, P, Na, Mg) v ovčím mléce, s výjimkou K. Hodnoty fosforu (950,1 H, 1016,9 B, 1042,6 W a 1596,7 mg.kg-1 C) u druhů byly spojeny s hodnotami hrubých nebo čistých bílkovin a kaseinu. (cs)
