for most cattle breeds originating in temperate climates. Just watch your cows to see when they start breathing heavier and faster or when they shade-up in the morning.” Dr. Tommy Perkins, executive vice presi-


dent, International Brangus Breeders Asso- ciation in San Antonio, says many southern producers realize the benefi ts of Brahman- crossed herds. “Bos indicus infl uenced cattle provide heat and parasite tolerance along with a higher level of disease resistance than straight Bos taurus cattle,” he says. “They also tend to produce at a high level


for a longer period of time than the same straight-bred Bos taurus cattle. Ultimately, they excel in less than ideal or desirable en- vironmental conditions by producing a profi t- able and very market-acceptable feeder calf.” Paschal says that in warmer climates, ex-


perience and research show that eared cattle have fewer health problems and can handle other aspects of hot climates. “They are more effi cient energetically,” he says. “They have excellent maternal ability; not just milk, but also maternal calving ease. “They are longer lived, due in part to


thicker enamel on their teeth. They are bet- ter at serum mineral conservation and have the ability to digest coarser forages.”


Calves feel the heat Heat stress doesn’t just affect the cow, it


affects the calf inside her. “That’s because she reduces blood fl ow to her internal organs and fetus, increasing blood fl ow at the skin
