ABSTRACT
Milk freezing point (MFP) as physical indicator is used for milk food chain
quality (MFCQ) control. Also udder health state (UHS) is important for MFCQ. This
paper was aimed to show some relationships of MFP to other milk UHS indicators.
There could be species differences. Cow milk was a reference to goat and sheep. Bulk
milk samples came from 3 dairy herds of Czech Fleckvieh cattle (B) and 1 goat and
sheep herd (White short-haired (W) and Tsigai (C)). Lactose (L), somatic cell count
(SCC) and natrium (Na) content as milk indicators (MIs) were investigated as UHS
indicators. Goat MFP was -0.5544 ± 0.0293 ºC and differed (P < 0.001) from B MFP -
0.5221 ± 0.0043 and C MFP -0.6048 ± 0.0691 ºC. The MIs in ruminants were relatively
normal with exception of higher SCC in W and C. The cow MFP was related to L (-
0.36; P < 0.01). MFP was not correlated to L (-0.07; P > 0.05) in W and was related to
L (0.40; P < 0.01) in C. In B it was in accordance with declared participation of L on
MFP (54%). Different W and C results could be explainable by worse SCC. Results
could be used for MFCQ control improvement.
