Change of stable microclimate during the spring and summer as a criterion of welfare and its effect on milk yield, composition and qualitative indicators as holstein dairy cows

Popis výsledku v původním jazyce

The aim of this research was to evaluate the change of microclimate as a criterion of welfare and its effect on average milk yield, composition and qualitative indicators in milk at the turn of spring and summer. Overall 25 bulk tank milk samples were analyzed in the period of 27. 5. 2013 to 20. 6. 2013. Samples were taken every day. The farm is situated in Žabčice (GPS49°0'51.786"N, 16°36'14.809"E). Measured properties were microclimate: barn airspace temperature (BAT), relative humidity (RH); averagemorning milk yield; milk composition: fat content (F), solids non-fat (SNF), protein content (P), lactose content (L) and qualitative indicators: active acidity (AA), titratable acidity (TA), density (D), rennet coagulation time (RCT), quality of curd (QC), somatic cell (SC). Based on the correlation of bulk milk samples of Holstein breed was found with increasing BAT increases AA (r = 0.84, P < 0.01), RCT (r = 0 .73,), reduces TA (r= -0.87, P < 0.01). In bulk milk samples was observed w
