Effect of stable microclimate on milk production of Holstein cows on the 2nd and 3rd lactation

Original language description

Aim of this paper was to evaluate the effect of stable microclimate on milk production of thirty high-producing Holstein cows on 2nd or 3rd lactation. Cows were stabled together in same conditions in loose housing stable with bedding. As microclimatic factors were monitored air temperature -T (Centi degree), relative humidity -RH (%) and counted temperature-humidity index -THI. The experiment was carried out in July (2007) and the whole month was divided into three periods (P1 12 days; P2 11 days; P3 8days). There were recorded 7 summers and 1 tropical day in the stable. RH varied from 40 to 80%, and THI were 7 days above 72. The mean difference between milk yields (kg/d) was only +1.0 kg in cows on 3rd lactation compared to cows on 2nd lactation. Wehave found that when the temperature in stable exceeds 21 degree up to the 30 degree (P2) with RH from 45% to 69% and THI from 66 to 79, the effective temperature was above the comfort zone for high--producing dairy cows. This event was a

Vliv stájového mikroklimatu na mléčnou produkci Holštýnských krav na 2. a 3. laktaci

Czech description

Cílem této práce je zhodnotit vliv stájového mikroklimatu na mléčnou produkci 30 Holštýnských krav na 2.a 3. laktaci. Krávy byly ustájeny společně ve stejných podmínkách ve volné, stlané boxové stáji. Z mikroklimatických faktorů byly sledovány: teplota vzduchu (T), relativní vlhkost (RH) a index THI. Experiment probíhal v červenci 2007 ve třech obdobích (P1 12dní, P2 11dní, P3 8dní).
