Abstract

THE age or experience of the ram, the number of ewes it has to serve and the management of the ram and ewe flock at mating time all influence the lamb-marking percentage.

These are the findings of a systematic research programme conducted over the period 1963 to 1955 by Dr. R. J. Lightfoot,* in collaboration with Mr. J. A. C. Smithf (1966) and continued by the author in the years 1967 to 1969.
