MAMMALIAN SEMIOCHEMISTRY ISSUES AND FUTURES, WITH SOME EXAMPLES FROM A STUDY OF CHEMICAL SIGNALLING IN CATTLE... 

In this paper we refer to current work of an interdisciplinary group at Bristol in the reproductive semiochemistry of cattle, and in particular on the chemical signals associated with estrus. Any findings which facilitate estrus detection in cattle would be of economic importance (Bailie, 1982) for every estrus missed, delays insemination for three weeks with the result that annual milk yields and beef production are reduced.
