Abstract:
This study evaluated whether shod status affects distal limb surface temperature in 43 healthy leisure horses using infrared thermography. Thermographic images of 16 regions of interest were acquired at rest from shod (n=23) and barefoot horses (n=20), with temperatures corrected for ambient temperature and wind speed. Significant thermal differences existed between anatomical regions (P<0.001), with frogs coolest (28.6±1.6°C) and tarsi/coronal bands warmest (29.7±1.5°C). Shod vs barefoot status showed no overall temperature effect (P=0.29), except cooler right hind frogs in barefoot horses (28.1±1.3 vs 29.1±1.6°C, P=0.034). In multivariable mixed-effects analysis accounting for repeated measures, sex was the only significant predictor (geldings 0.8°C warmer than mares, P=0.048), while age was non-significant (P>0.7). These findings indicate shod status has minimal impact on resting distal limb thermography in leisure horses.

Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...
Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
