Abstract
Extract Sir.—I refer to the paper by Day( 1 Day, A. M. 1979. Induced termination of the calving season. N.Z. vet. J., 27: 22–29. [Taylor & Francis Online], [Web of Science ®] [Google Scholar] ) on induction of parturition in a dairy herd. This report was read with a considerable degree of interest as it included results which are significantly different from those which we would have expected from extensive field experience in New Zealand and overseas.
