Abstract

The detection of estrus-related odorous substances excreted in urine by estrous cows was studied by a behavioral assay method which offers the promise of quantifying the concentraton of such substances. Laboratory rats were trained according to operant conditioning procedures to press a disk in the presence of air that had passed through urine samples collected from estrous cows. The same behavior was extinguished in the presence of air that had passed through urine samples collected from diestrous cows. It was shown that the rats were able to generalize this discrimination training from known training samples to unknown test samples with a 65% level of accuracy.
