The effects of sample fat value manipulation on raw cow milk composition and indicators.

Popis výsledku v původním jazyce

Values of milk indicators (MIs) can be influenced by sampling errors and milk manipulation. This paper estimated the freezing point depression (FPD) and other MIs drifts which can cause fat movement. That is important for: - preparation of reference milksamples (MSs) for proficiency testing and instrument calibrations; - estimation of the impact of milk treatment as centrifugation in dairy plants on FPD. Five MSs (A = original milk; milk with modified fat (F) content; B = less F, C = low F, D = more F,E = high F) were created (gravitation F separation at 4 °C for 12 hours) with the same milk matrix 12x per year. F averages increased by 4.80% (122.1%) from 1.68 to 6.48% due to manipulation. It increased variability of MIs especially for SNF (solids non fat), L (lactose) and CP (crude protein). SCC (somatic cell count) averages increased by 803 (196.8%) from 9 to 812 thousand.ml?l. Correlation (r) F x SCC was 0.85 (P { 0.001). SNF, L and CP averages decreased by 0.47% (5.3%), 0.31% (6.
