Analyse of relationships between freezing point and selected indicators of udder health state among cow, goat and sheep milk
Result description
Milk freezing point (MFP) is important. Aim was to analyse the relationships of MFP to udder health milk indicators (MIs) by comparison between cows (reference), goats and sheep. Bulk milk samples came from 3 herds of Czech Fleckvieh (B, n 93) and 1 goatherd and sheep flock (White short-haired, W, n 60; Tsigai, C, n 60). Investigated MIs: DM, dry matter; SNF, solid non fat; L, lactose (all in %); SCC, somatic cell count (103 ml-1); EC, electrical conductivity (mS cm-1); MFP (°C); Na and K (in mg kg-1).W MFP was ?0.5544 + 0.0293, B ?0.5221 + 0.0043 and C ?0.6048 + 0.0691 ?C. The B MFP was related to L (?0.36; P < 0.01), W was not related to L (?0.07; P > 0.05) and C was related to L (0.40; P < 0.01). It is explainable by worse SCC for used W (3,646 103 ml-1) and C (560 103 ml-1) milk. Only 0.5 and 10.5% of variations in MFP were caused by variations in DM and SNF in B, 32.7 and 12.8% in W but already 49.4 and 45.0% in C. Higher C values were caused by high MFP variability, 11.8% (C) v
