Abstract
ALTHOUGH there is wide interest in hormonal induction of multiple births in cattle1, it is not possible to induce two or three ovulations reliably. Further advances will require a better understanding of the patterns of hormone concentrations during follicle growth. This report describes peripheral plasma concentrations of oestrogens, progesterone and luteinizing homone (LH) during the 96 h before induced oestrus and multiple ovulations.
