The Influence of Low Environmental Temperatures on Intramammary Temperatures^*

Iowa Agricultural Experiment Station, Ames, Iowa

ABSTRACT

Conclusions: When cows were kept in a barn where the temperature varied between 58° and 70° F., the temperatures of their udders (teats and milk cisterns) averaged 2.5° to 3.0° F. lower than their rectal temperature. When cows were exposed to sub-zero weather the observed differences increased to around 5° F. The movement of the cows into the barn and the washing of the udder before inserting the thermometer into the gland cistern decreased the actual difference between rectal and udder temperatures. Otherwise, greater differences would have been observed.
