Effect of barn airspace temperature on composition and technological parametres of bulk milk produced by dairy cows of czech fleckvieh and holstein breeds

Popis výsledku v původním jazyce

On two farms (A and B), samples of bulk milk produced by dairy cows of the Holstein (H) and Czech Fleckvieh (CF) breeds were collected every week on the same day within the time interval of 36 weeks. The aim of this sampling was to determine the effect of barn airspace temperature on milk compositon and its technological parameters. The following average values of all bulk milk samples (n = 72) were recorded: barn airspace temperature (BAT) 12.08 °C; rennet coagulation time (RCT) 211 sec.; curd qualityclass (CQC) 1.53; titratable acidity (TA) 7.16 °SH; protein content (P) 3.46 %; fat content (F) 4.09 %; lactose content (L) 4.79 %; and solids non fat (SNF) 8.86 %. As compared with H, dairy cows of CF breed produced milk with statistically significantlyhigher (P < 0.01) contents of P (+0.27 %) and SNF (+0.26 %). The remaining differences were statistically insignificant (P > 0.05): BAT (-2 °C); RCT (-4 sec.); CQC (0 class); TA (+0.11 °SH); F (+0.05 %) and L (-0.03 %). As far as the eff
