dc.description.abstract |
Heat stress occurs when a dairy cow’s
internal heat load is greater than her capacity
to lose unwanted heat to the environment.
Effects of heat stress include: increased
respiration rate, increased water intake, increased
sweating, decreased dry matter intake,
slower rate of feed passage, decreased
blood flow to internal organs, decreased milk
production, and poor reproductive performance.
Lower milk production and reproductive
performance cause economic losses
to dairy producers. The ordered priorities for
reducing heat are: increasing water availability;
providing shade in the housing areas
(both dry and lactating cows) and holding
pen; reducing walking distance to the parlor;
reducing time in the holding pen; improving
holding pen ventilation and freestall ventilation;
adding cooling for the holding pen and
exit lane; cooling close-up cows (3 wk before
calving); cooling housing for fresh and earlylactation
cows; and cooling housing for midand
late-lactation cows. |
