Abstract
Extract
Having imported a 15-month-old Clun Forest ram from England with the intention of grading-up the small-bodied native ewe indigenous to the Kenya Highlands it was something of a shock to find the weight of the ram when loaded aboard the Mombasa-bound ship was no less than 250 lb. On arrival, he appeared to have lost little if any weight during the three weeks spent upon the journey, and it was very apparent that to let him loose in a flock of ewes, the average weight of which was little more than 50 lb, was asking for serious trouble, with probably few lambs to show for it at the end of the season. In any case, if the grading-up process was to be of any real value, this ram would have to sire far more ewes than he was physically capable of, even in normal circumstances of weight and size. As a result of this, artificial breeding was developed as a flock policy.
