[QUOTE="Global ovine, post: 7128099, member: 493"] See [USER=348]@neilo[/USER] reply for that question. However very few flocks of any breed or cross are genetically the same to respond identically to an increase in body weight to achieve the same gain in ovulation rate, eventually lambs on the ground. The 2.1 extra eggs shed per kilogram of body weight (1.9 extra lambs due to partial litter loss) is a general rule across all common commercial breeds of UK origin. Fat and obese ewes are at the top end of the curve showing diminishing returns, ie. a waste of feed. Between flock differences in response, if all trace elements are adequate, are due to the breeders goals for selection on litter size, be they hill sheep breeders and/or BFL breeders. Increase genetic uniformity for fecundity will only exist if one or both of those breeds have very little genetic diversity (highly inbred and few significant progenitor sires). The UK has a high proportion of pedigree breeders to commercial farmers and don't all do everything off the same page. The genetic difference between breeders would also be expected to be large when the majority of breeders do not measure and rank phenotype for selection. Therefore some flocks of Mules will not be equal to other flocks. [/QUOTE]
