During image analyses, pictures taken 499 good quality included. The both sexes various ages (minimum 3 years, pubertal adult stages), they had diverse physiological statuses (breeding, immature, lactating, non-lactating, pregnant). Before taking pictures, ambient humidity registered a weather station, light intensity lux meter. ET associated only with status (p < 0.05), pregnant females showing lowest values, while no effects status, sex, or age found FT. showed positive correlation (r = 0.7887) FT 0.6280), highlighting sensitivity camel thermoregulation fluctuations. As expected, strong 0.6643) found. Conversely, negative observed (−0.7444) (−0.5519), indicating that higher levels lead decreased temperatures regions.

Unique temperature change patterns in calves eyes and muzzles: a non-invasive approach using infrared thermography and object detection

Frontiers in Veterinary Science, Journal Year: 2025, Volume and Issue: 12

Published: March 10, 2025

This study investigates the potential of non-invasive, continuous temperature measurement techniques for assessing cattle welfare. We employed advanced object detection algorithms and infrared thermography to accurately extract continuously measure temperatures eyes muzzles 11 calves over several months (total, 33 samples). A mobile thermal imaging camera was paired with Mask R-CNN algorithm (object detection) trained on annotated datasets detect eye muzzle regions accurately. Temperature data were processed by outlier rejection, standardization, low-pass filtering derive change patterns. Cosine similarity metrics permutation tests evaluate uniqueness these patterns among individuals. The average cosine between changes in same individual across samples 0.72, yielding p -values &lt;0.01 most samples, indicating pattern uniqueness. highlights high-frequency, non-invasive measurements detecting subtle physiological animals without causing distress.

Use of Infrared Thermography and Heart Rate Variability to Evaluate Autonomic Activity in Domestic Animals

Animals, Journal Year: 2024, Volume and Issue: 14(9), P. 1366 - 1366

Published: May 1, 2024

Most of the responses present in animals when exposed to stressors are mediated by autonomic nervous system. The sympathetic system, known as one responsible for “fight or flight” reaction, triggers cardiovascular changes such tachycardia vasomotor alterations restore homeostasis. Increase body temperature stressed also activates peripheral compensatory mechanisms cutaneous vasodilation increase heat exchange. Since skin blood flow influence amount dissipation, infrared thermography is suggested a tool that can detect said changes. review aims analyze application method assess stress-related activity, and their association with heart rate variability domestic animals.
