ABSTRACT
Pourjafar M, Badiei K, Chalmeh AA, Rahmani Shahraki AR, Naghib M., Body temperature in horses, cattle, sheep and
goats measured by mercury, digital and non-contact infrared thermometers,
Online J Vet Res., 16 (4):195-203, 2012. Temperatures were measured in groups of 50 (25 male
and 25 female) healthy DareShuri horses, Holstein cattle,
Karakul sheep and Najdi goats. Rectal and vaginal
temperatures were taken with medical and veterinary mercury and digital rectal,
and non-contact infrared thermometers.
Regression curves for veterinary mercury rectal and infrared thermometers
were y= -0.021x+38.32, y= 0.061x+36.3, y= -0.199x+47.41 and y= -0.022x+38.89
for horse, cattle, sheep and goat, respectively where y= veterinary mercury
rectal and x= infrared thermometers. Infrared detected temperatures in cows
(38.1±0.6oC) and goats (39.1±0.7oC) were significantly
lower compared with other methods, but in horses (37.4±0.2oC) and
sheep (39.4±0.3oC) were not different. We report reference values
for body temperature detected by traditional and infrared thermometers for
large animal practice. The regression plots could be used to convert infrared
to rectal temperatures.
Keywords: Body temperature; Rectal thermometers; Non-contact infrared thermometer; Large
