Beak temperature change in response to acute stress in laying hens measured using infrared thermography
نویسندگان
چکیده
The aim of this study was to investigate beak surface temperature changes stress induced by fear resulting from tonic immobility using infrared thermography in laying hens. It also examined whether temperatures differed among brown and white lines. based on 89 hens both lines: 45 White Leghorn birds 44 Hy-Line birds. Beak measured with immediately before after testing. average obtained the upper lower area measurements. had significantly higher than Birds shorter longer immobility. An interaction effect stimulus (before immobility) time significant. (P<0.001) decreased response test Brown lower-beak compared Based these results, experienced that were detectable thermography. Therefore, could be used as a non-invasive technique assess stress. Infrared improve ability evaluate under potentially stressful conditions.

Skin temperature response to unilateral training measured with infrared thermography
This study aimed to identify the skin temperature (Tsk) behavior to understand the acute cross-effect after unilateral training of lower-limbs. Seventeen healthy young men (weight, 75.2±5.5 kg; height, 1.8±0.1 m; age, 22.5±1.6 years) were divided into two groups: high-trained (n=8) and low-trained (n=9). All participants performed: (a) one-repetition maximum (1RM) testing protocol on the leg pr...

conclusions there were significant distinctions in the skin temperature distribution during exercise according to the activity of the area under consideration during exercise, which may be important in the development of physiological models and heat flux analyses for different purposes. results during pre-exercise, all tsk reached a steady-state (p ≤ 0.05), which ensured adequate thermal stabi...
متن کاملInfrared beak treatment method compared with conventional hot-blade trimming in laying hens.
Infrared lasers have been widely used for noninvasive surgical applications in human medicine, and their results are reliable, predictable, and reproducible. Infrared lasers have recently been designed for the express purpose of providing a less painful, more precise beak-trimming method compared with conventional beak trimming. This study was designed to examine the potential of the infrared (...
متن کاملThe Possibility of Using Watermelon Waste in Laying Hens Diets
In this experiment 240 Hy-Line (W-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. The amounts of watermelon skin meal (WSM) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. The results showed that using WSM up to 2% significantly improved the performance and...
