Description
| - Bylo provedeno srovnání kozího mléka s mlékem kravským ve vztahu k bodu mrznutí mléka (MFP) jako ukazateli mléka (MI). Byly vyšetřeny bazénové vzorky mléka ((BMSs). Kozy (Bílá krátkosrstá (W), n = 60 BMSs) a krávy (Český strakatý skot (B), n = 93) byly vzorkovány po 3 roky. Kozí mléko má nižší hodnotu MFP (-0,5544 °C; W) než kravské (–0,5221 °C; B; P < 0,001). Mezidruhové rozdíly ovlivnily obsahy některých MIs: tuk (4,58 W vs. 3,40% B; P < 0,001); močovina (50,6 W vs. 26,7 mg 100ml-1 B; P < 0,001); kalcium (1224 W vs. 1300 mg l-1 B; P < 0,01). Obsah laktózy (monohydrát) byl 4,43 W vs. 5,06% B (P < 0,001). Některé významné vztahy byly pozorovány mezi kozím MFP a: tukem (-0,48, P < 0,001, W vs. -0,06, P > 0,05, B); obsahem sušiny (-0,57, P < 0,001, W vs. -0,07, P > 0,05, B); močovinou (-0,57, P < 0,001, W vs. 0,01, P > 0,05, B); pH (0,75, P < 0,001, W vs. -0,455, P < 0,001, B); Ca (-0,48, P < 0,01 W vs 0,12, P > 0,05, B); kaseinem (-0,42, P < 0,01, W vs. -0,10, P > 0,05, B) atd.

- The comparison of goat milk with cow milk in relations to the milk freezing point (MFP) as milk indicator (MI), was carried out. The bulk milk samples (BMSs) were investigated. Goats (White short-haired (W), n = 60 BMSs) and cows (Czech Fleckvieh cattle (B), n = 93) were sampled for 3 years. Goat milk takes the lower value of MFP (-0.5544 °C; W) than cow´s (–0.5221 °C; B; P<0.001). Species differences influenced the contents of some MIs: fat (4.58 W vs. 3.40% B; P < 0.001); urea (50.6 W vs. 26.7 mg 100ml-1 B; P<0.001); calcium (1224 W vs. 1300 mg l-1 B; P < 0.01). The content of lactose (monohydrate) was 4.43 W vs. 5.06% B (P<0.001). Some significant relations were observed between goat MFP and: fat (-0.48, P<0.001, W vs. -0.06, P>0.05, B); dry matter content (-0.57, P < 0.001, W vs. -0.07, P > 0.05, B); urea (-0.57, P < 0.001, W vs. 0.01, P > 0.05, B); pH (0.75, P < 0.001, W vs. -0.455, P < 0.001, B); Ca (-0.48, P < 0.01 W vs 0.12, P > 0.05, B); casein (-0.42, P < 0.01, W vs. -0.10, P > 0.05, B) etc.
