In his regular weekly BeefTalk column, North Dakota State Extension Service beef specialist Kris Ringwall notes the current North American heat wave combined wth high humidity and relatively calm winds have caused considerable loss of life among cattle.
He warns that this is not just a problem with feedlot cattle and that night temperatures which fail to fall below 70 F, in combination with the daytime heat, are also a threat.
Ringwall’s full column with references to websites which help assess heat stress is available here.
