milk production by 20-30% for lactating dairy cows.
Corresponding responses by goats to THI have not been
determined, but heat stress defi nitely can reduce milk pro-
duction. To reduce heat stress of dairy does, a number of
management changes can prove to be useful, including (1)
feeding smaller portions of the ration more frequently, (2)
feeding during cooler times of the day or under shade with
Magnesium
Higher magnesium may be
needed with N and K
fertilized pastures to prevent
hypomagnesemia
