Effect of maximal micro-climatic values in stable on milk production of holstein cows on 2nd lactation

Popis výsledku v původním jazyce

Aim of this study was to investigate influence of maximal micro-climatic values in stable on milk production of Holstein cows on 2nd lactation. Fifteen Holstein cows on 2nd lactation were kept together in identical conditions in loose housing stable withbedding and fed ad libitum a complete ration. Cows were milked twice a day at 4.00 and 16.00 h. In the period from 1st May to 26th August 2009 (118 days) were monitored parameters of stable microclimate and daily milk yield. As stable microclimatic values were monitored air temperature (degree), relative humidity (%) and counted temperature--humidity index (THI). The average milk yield was 32.6 kg per day. Maximal daily temperature resp. THI reached 35.3 degree resp. 82.7 with mean 26.4 degree resp. 72.3. The milk production was mostly influenced by maximal resp. average daily THI (r= -0.55 resp. r= -0.57).
