Evaluation of the result reliability of basic milk composition in an automated milking system through indirect real-time analysis

Popis výsledku v původním jazyce

Current and regular, preferably everyday, knowledge of the milk composition and properties is important for controlling the dairy herd health status, prevention of the occurrence of their production disorders and promoting of milk quality. Therefore, the validation of the result reliability of milk analyzes by system of real milk analyzes (RTA) in the automated milking system (AMS) was performed. Fat (F), crude protein (P), lactose monohydrate (L), solids non fat (SNF) contents and somatic cell count (SCC) were determined. This was done by a direct statistical comparison of the parallel measured results (RTA and relevant reference - infrared spectroscopy (MIR; F, P, L, SNF) and flow cytometry (FC; SCC)) in 30 individual cow milk samples. The results of RTA reliability in AMS as coefficients of determination (R) and correlation (r) of results between methods (RTA and reference) were as follows: - r between MIRxRTA methods for F, P, L and SNF 0.524 (P&lt;0.01), 0.744, 0.701 and 0.731 (P&lt;0.001); - R explains 27.5, 55.3, 49.2, and 53.5% of the RTA variability by reference method (MIR). For SCC it was 0.758 (P&lt;0.001) and 57.4% variations in RTA values can be explained by FC variability. The reliability of the results of RTA milk analyzes in the AMS has been found to be suitable for the above mentioned purposes after appropriate comparison.
