Vulvar skin temperature changes significantly during estrus in swine as determined by digital infrared thermography
نویسنده
چکیده
Materials and methods: The experimental groups consisted of 25 gilts and 27 multiparous sows. Infrared VST and gluteal skin temperature (GST) were measured twice daily (8:00 am and 4:00 pm) using a thermal-imaging camera (Fluke IR FlexCam; Fluke Corporation, Everett, Washington). Once standing estrus was observed, transrectal real-time B-mode ultrasonography was performed twice daily (8:00 am and 4:00 pm) to monitor follicle development and determine time of ovulation. Mean VST and GST (± SEM) were reported and compared using MANOVA and Tukey-Kramer tests in SAS 9.1 (SAS Inc, Cary, North Carolina). Significant differences were reported at P < .05.

Infrared Thermography of Swine Body Surface Temperatures and Associatedrectal Temperatures during an Acute Respiratory Disease Challenge
An acute Actinobacillus pleuropneumonia challenge was used to study changes in rectal and radiant surface temperatures over 18 h. From 3.5 to 15 h after challenge, rectal temperatures were elevated in challenged pigs compared to nonchallenged controls. From 6 through 18 h after challenge, infrared surface temperature was higher for challenged pigs versus control nonchallenged pigs. Correlation ...
متن کاملUse of infrared thermography in children with shock: A case series
Shock is a complex clinical syndrome caused by an acute failure of circulatory function resulting in inadequate tissue and organ perfusion. Digital infrared thermal imaging is a non-invasive technique that can detect changes in blood perfusion by detecting small changes in the temperature of the skin. In this preliminary study, eight pediatric patients (five boys, three girls), ages ranging fro...

BACKGROUND The aim of the study is to evaluate the effectiveness of thermographic monitoring, using the temperature changes of perianal and perivulvar areas for the determination of estrus in Anatolian Shepherd bitches. Fifteen bitches were used in the study. Blood and vaginal smear samples were collected and thermographic monitoring of perianal and perivulvar areas were carried out starting fr...

The goal of this paper is to examine the effects of laser radiation on the skin wound healing using infrared thermography as non-invasive method for the monitoring of the skin temperature changes during laser treatment. Thirty Wistar rats were used in this study. A skin lesion was performed at the leg on all rats. The animals were exposed to laser radiation (λ = 670 nm, P = 15 mW, DP = 16.31 mW...
