Effect of milking frequency on milk production of holstein cows during winter and summer period
Original language description
The objective of this study was to determinate the effect of milking frequency on milk production of Holstein cows during winter and summer. Total number of cows was divided into two groups by milk yield. Almost 40 % of cows milked more than 25 kg of milk per day per cow so cows are milked twice during the morning. The other more than 60 % of dairy cows milked per day less than 25 kg of milk per day, and these cows are milked once during the morning. In summer and winter period were monitoring the average daily temperature in the barn (BAT) and the stable relative humidity (RH). The study lasted 177 days (data analyzed daily) in the summer (from 1 June 2013 to 31 August 2013) and in winter period (from 1 December 2013 to 23 February 2014). Data comes from University farm. The farm is situated in Žabčice (GPS49°0'51.786"N, 16°36'14.809"E). Based on the correlation of milk production data of Holstein breed was found with increasing BAT reduces average morning milk yield per twice milked
