Thermal changes in cow's mammary gland after experimentally invoked inflammation (mastitis).

Abstract

The purpose of the study was the evaluation of the thermal changes within mammary gland in cows, after experimentally invoked inflammation, developed as a result of 60 ml of 20% NaCl solution given directly into the udder (A and D quarters). Three hours after injection, the increased' temperature of teats and their bases by 2.26 degrees C and 0.58 degree C, respectively, was stated. The temperature was still increased after 6 hours from NaCl solution injection. It was accompanied by increase of heat flux from the skin surface by 50.17 mW/cm2 taken from the teat surface, and by increased values of Burton Index--the tissue blood supply index.
