A device was developed to monitor rectal temperature automatically in cattle for application in research settings. Compared with manual measurement of rectal temperature, this device decreases labor and time requirements and allows data collection without the influence of animal handling or restraint. The device consists of a custom-fabricated aluminum tail harness that supports an indwelling r...

Electromagnetic spectra reduce melatonin production and delay the nadirs of rectal temperature and heart rate. Seven healthy men (16-22 yrs) completed 4 permuted sessions. The control session consisted of a 24-hours bedrest at < 30 lux, 18 degrees C, and < 50 dBA. In the experimental sessions, either light (1500 lux), magnetic field (16.7 Hz, 0.2 mT), or infrared radiation (65 degrees C) was ap...

Several temperature-humidity indexes (THI) have been used to estimate the degree of thermal stress experienced by dairy cows. The present objectives were to develop equations using meteorological variables that predicted rectal temperature of lactating cows in a subtropical environment and compare the goodness of fit of these equations to those using 8 different THI. Rectal temperature was meas...

BACKGROUND AND OBJECTIVES The consequences of missing fever in children can be grave. Body temperature is commonly recorded at the axilla but accuracy is a problem. This study aimed to evaluate the accuracy of a tympanic thermometer in the paediatric emergency setting. METHOD In a total of 106 infants, the body temperature was measured in the daytime with an infrared tympanic thermometer, and...

BACKGROUND Fever in patients can provide an important clue to the etiology of a patient's symptoms. Non-invasive temperature sites (oral, axillary, temporal) may be insensitive due to a variety of factors. This has not been well studied in adult emergency department patients. To determine whether emergency department triage temperatures detected fever adequately when compared to a rectal temper...

Three neonates with rectal perforations probably caused by the use of the rectal thermometer, are reported. The dangers of this condition and the difficulty of diagnosis even at laporatomy are emphasised. It is suggested that since the axillary temperature in the neonate is an adequate reflection of the core temperature the routine use of the rectal thermometer, except in exceptional circumstan...

Ninety-six Large White growing barrows were used to determine the effect of temperature on thermoregulatory responses during acclimation to increased ambient temperature. Pigs were exposed to 24°C for 10 d and thereafter to a constant temperature of 24, 28, 32, or 36°C for 20 d. The study was conducted in a climate-controlled room at the INRA experimental facilities in Guadeloupe, French West I...

The comparative performance of shaded and unshaded Zebu cross steers was studied in a Queensland feedlot from January to May 1992. The provision of shade gave no significant (P > 0.05) advantage in liveweight gain (182 V. 177 kg), feed conversion ratio (9.4 v. 9.8 kg of fresh feed/kg liveweight gain), carcase weight, dressing percentage, P8 rump fat, eye muscle area, saleable meat yield, meat c...

OBJECTIVE Measurement of rectal temperature is the most common method and considered gold standard for obtaining body temperature in dogs. So far, no study has been performed comparing agreement between rectal and auricular measurements in a large case series. The purpose of the study was to assess agreement between rectal and auricular temperature measurement in normothermic, hypothermic, and ...

A study on the effects of different color temperatures of fluorescent lamps on skin and rectal temperatures in a moderately cold environment involving Ci) changes in skin temperature of 7 male subjects exposed to an ambient temperature ranging from 28"C to 180C (experiment I) and (ii) changes in skin and rectal temperatures and metabolic heat production of 11 male subjects exposed to ambient te...
