Core body temperature monitoring with passive transponder boluses in beef heifers

Microchip transponder thermometry for monitoring core body temperature of antelope during capture.

Hyperthermia is described as the major cause of morbidity and mortality associated with capture, immobilization and restraint of wild animals. Therefore, accurately determining the core body temperature of wild animals during capture is crucial for monitoring hyperthermia and the efficacy of cooling procedures. We investigated if microchip thermometry can accurately reflect core body temperatur...

Comparing new-technology passive warming versus traditional passive warming methods for optimizing perioperative body core temperature.

Hypothermia puts surgical patients at risk for adverse outcomes. Traditional passive warming methods are mostly ineffective in reducing hypothermia. New-technology passive warming holds promise as an effective method for promoting and sustaining normothermia throughout surgery. The purpose of this retrospective cohort study was to compare the effectiveness of new-technology passive warming with...

Body composition and metabolic profiles associated with puberty in beef heifers.

Rapid growth large frame (RL, n = 61) or average growth medium frame (AM, n = 71) biotype heifers fed to achieve either moderate (MOD, .6 kg/d) or high ADG (HI, 1.0 kg/d) were used to determine whether puberty occurs at similar body composition or metabolic status. A heifer was considered pubertal after being detected in estrus and then forming a functional corpus luteum. Live animal estimates ...

Reproductive Management of Beef Heifers

Implications of Changes in Core Body Temperature

Dairy farmers and veterinarians have used body temperatures, most commonly rectal temperatures, to detect and manage febrile disease and changes in the state of cows (estrus and onset of calving) for many years. Mastitis, pneumonia, metritis, lameness, estrus, onset of parturition, heat stress, and subacute ruminal acidosis (SARA) are among the physiological conditions potentially correlated wi...
