Maximum IRT muzzle (-) temperatures, vulval (:) temperatures, and
P4 (–) concentration in relation to time to ovulation. The values at 4-

different letters indicate significant differences between time points (P

Proctor, H. S.; Carder, G. (2015) Nasal temperatures in dairy cows are influenced by positive
emotional state. Physiology & Behavior 138, S. 340–344.
Total mean nasal temperature (°C) for each measurement.
We found that the nasal temperatures of cows dropped as a result of the experience of a positive, low arousal
experience. The stroking stimulus is known to induce a state of relaxation and lower the heart rate of cows. This
leads us to conclude that the drop in nasal temperature was indicative of the change in valence, rather than a
change in arousal. 11

before claw trimming. The thermal images show temperature differences (°C) on coronary band
between lesion (A) and nonlesion (B) hind claws.
12
Conclusions: This study established the potential of IRT as a
reliable, practical tool for detection of lesions, without having
to clean or lift feet but could not be used to differentiate
between lesions.

15
Conclusions: Contrary to expectation, the elands
exposed to cold environmental temperatures had low
surface temperatures, similar to cattle. This suggests
that the eland has the potential to adapt to winter
housing conditions in temperate climatic zones with
inside temperatures above 0 1C.

Conclusions: The
results demonstrate
that infrared udder
temperatures can be
a good auxiliary
diagnostic method
to mastitis in sheep,
principally to
subclinical mastitis.

The results indicated that the young broilers
fed the high-energy diet presented a
metabolic energy loss equivalent to 0.64
kcal h-1, while the birds fed with the control
diet lost 2.18 kcal h-1. This finding confirms
that oil supplementation to the diet reduces
bird heat loss.

of individual broilers (a) and of the flock (b).

Two regions of interest were used for the analysis: one around the hole of
the blackbody and the other around the hotter parts of the chicken's face.

Conclusions: IRT is a good tool to assess thermal losses in
rabbits. Maximum and minimum temperatures on eyes, nose,
internal and external ear are suitable for detecting differences
in heat stress in rabbits.
Mean maximum temperatures ± SE found in trial 2 and 3 on rabbits’ eyes, nose, internal ear and external ear in rooms A (in
grey) and B (in white). In all cases, differences are significant at P < 0.001. 19

Total mean nasal temperature (°C) for each measurement. We found that the nasal temperatures of cows dropped as a result of the experience of a positive, low arousal experience. The stroking stimulus is known to induce a state of relaxation and lower the heart rate of cows. This leads us to conclude that the drop in nasal temperature was indicative of the change in valence, rather than a change in arousal. 11

  1. لأشعة تحت الحمراء هي نوع من الأشعة الكهرومغناطيسية مثلها مثل امواج الراديو والأشعة فوق البنفسجية وأشعة اكس والميكروويف. ضوء الأشعة تحت الحمراء جزء من الطيف الكهرومغناطيسي الذي نتعامل معه في حياتنا اليومية، بالرغم من اننا لا نلاحظه. ان الأشعة تحت الحمراء غير مرئية لعين الانسان لكننا نشعر بها كحرارة. تعتبر الأشعة تحت الحمراء IR radiation من احد الطرق الثلاثة لانتقال الحرارة من مكان لاخر والانواع الثلاثة هي الاشعاع radiation والحمل convection والتوصيل conduction. كل شيء له درجة حرارة اعلى من 5 درجات كلفن اي ما يعادل 268 تحت الصفر يصدر منه أشعة تحت حمراء. تعطي الشمس اكثر من نصف طاقتها في صورة أشعة تحت حمراء وجزء من طيفها المرئي يمتص ويعاد انبعاثه في صورة أشعة تحت حمراء. تحول مصابيح الضوء  10٪ من الطاقة الكهربائية إلى ضوء مرئي وحوالي 90٪ منها يتحول إلى أشعة تحت حمراء. معظم الأجهزة الكهربائية مثل المصابيح والتوستر وفرن الكهرباء تستخدم الأشعة تحت الحمراء في نقل الحرارة، حتى الأجهزة الصناعية المستخدمة في التجفيف ومعالجة المواد. كل هذه التطبيقات تعمل كجسم اسود للاشعاع ومعظم طاقتها عند طول موجي اصغرمن الطول الموجي للضوء المرئي، مع انبعاث للطاقة في منطقة الضوء المرئي باللون الاحمر. جهاز التحكم في التلفزيون يستخدم امواج الأشعة تحت الحمراء لتغير القنوات والتحكم في كل وظائفه. يوجد في جهاز التحكم دايود LED باعث للضوء تحت الاحمر او ليزر يرسل اشارات ثنائية مشفرة في صورة نبضات تمثل حالتي الفتح والاغلاق on/off. على جهاز التلفزيون يوجد كاشف يعمل على تحويل نبضات الضوء إلى اشارات كهربائية تعطي تعليمات للميكروبروسيسور ليقوم بوظيفة محددة حسب الاشارة المرسلة مثل تغير القنوات او التحكم في شدة الصوت وغيرها من الوظائف. يمكن استخدام جهاز ليزر الأشعة تحت الحمراء في عملية الاتصالات بين نقطتين على مسافة تصل إلى عدة مئات من الامتار. الطول الموجي والتردد Wavelength and frequency ينتقل الاشعاع الكهرومغناطيسي في صورة امواج او جسيمات عند اطوال موجة وترددات مختلفة. هذا المدى الواسع من الاطوال الموجية يعرف باسم الطيف الكهرومغناطيسي electromagnetic spectrum.  يقسم الطيف إلى سبعة اقسام مختلفة من حيث الاطوال الموجية لها. تتدرج اقسام الطيف الكهرومغناطيسي من الاقل تردد إلى الاعلى تردد وتعرف تلك الاقسام بامواج الراديو والميكروويف والأشعة تحت الحمراء والضوء المرئي والأشعة فوق البنفسيجة وأشعة جاما. تمتلك الأشعة تحت الحمراء اطوال موجية اطول من الضوء المرئي. وتقع الأشعة تحت الحمراء في مدى الطيف الكهرومغناطيسي بين الميكروويف والضوء المرئي. تمتلك ترددات من 3GHz وحتى 400THz واطوال موجية في المدى من 30cm وحتى 740nm. الأشعة تحت الحمراء غير مرئية لعين الانسان لكن نشعر بها كحرارة اذا كانت شدتها عالية بما فيه الكفاية.
  2. Skin temperature also increased with increasing THI For Skin temperature we observed a very interesting continuously increase with increasing THI to a ceiling value. This gradual increase of ST with increasing THI complicates the identification of an optimal heat stress threshold. Increasing levels of protein % in milk tended to increase ST cows at the extreme end of the THI scale. This inecrease in protein % could be due to reduced dry matter intake, causing declaration of an animals’ metabolism. The same tendency observed for effect of protein level on the other physiological traits
