    The relations of sheep´s and cow´s freezing point of milk to its composition and properties

  • Original language description

    Aim of this work was to investigate the sheep and cow milk composition, properties and milk freezing point (MFP) as an important milk indicator (MI). Data sets of sheep (Tsigai (C), n = 60) and cows (Czech Fleckvieh cattle (B), n = 93) bulk milk samples(BMSs) were investigated. Sheep milk showed the lower MFP value (-0.6048 °C; C) than cow milk (?0.5221 °C, B). Mentioned differences influenced also the contents of some components: fat (7.58% C vs. 3.40% B, P < 0.001); urea (63.6 mg.100mL-1 C vs. 40.4 mg.100mL-1 B, P < 0.001); calcium (1915 mg.L-1 C vs. 1172 mg.L-1 B, P < 0.001) etc.. Lactose content is in opposite constellation 4.44% C vs. 5.06% of monohydrate B (P < 0.001). Some significant relations were observed between sheep MFP and: lactose (0.395, P < 0.01, C vs. -0.355, P < 0.01, B, which is quite unusual); solids non fat (-0.670, P < 0.001, C vs. -0.324, P < 0.01, B); titration acidity (-0.491, P < 0.001, C vs. -0.329, P < 0.01, B); pH (0.926, P < 0.001, C vs. -0.455, P < 0.00

    Vztahy bodu mrznutí ovčího a kravského mléka k jeho složení a vlastnostem

  • Czech description

    Cílem této práce bylo vyšetřit složení a vlastnosti ovčího a kravského mléka a bod mrznutí mléka (MFP) jako významného mléčného ukazatele (MI). Byly vyšetřeny bazénové vzorky mléka (BMSs) ovcí (Cigája (C), n = 60) a krav (český strakatý skot (B), n = 93). Ovčí mléko vykázalo nižší hodnotu MFP (-0,6048 °C; C) než mléko kravské (?0,5221 °C, B). Tyto rozdíly ovlivnily také obsahy některých složek: tuk (7,58% C vs. 3,40% B, P < 0,001); močovina (63,6 mg.100mL-1 C vs. 40,4 mg.100mL-1 B, P < 0,001); vápník (1915 mg.L-1 C vs. 1172 mg.L-1 B, P < 0,001) etc.. Obsah laktózy je v opačné konstelaci 4,44% C vs. 5,06% monohydrátu B (P < 0,001). Byly pozorovány některé významné vztahy mezi ovčím MFP a: laktózou (0,395, P < 0,01, C vs. -0,355, P < 0,01, B, což je poněkud neobvyklé); sušinou tukuprostou (-0,670, P < 0,001, C vs. -0,324, P < 0,01, B); titrační kyselostí (-0,491, P < 0,001, C vs. -0,329, P < 0,01, B); pH (0,926, P < 0,001, C vs. -0,455, P < 0,001, B) atd.
