Well or poorly reared ewes were differentially fed at 1 of 5
pasture allowances for 6 weeks prior to a synchronised mating. Rearing
class and flushing treatment significantly affected ovulation rate. The
well and poorly reared ewes had mean multiple ovulation rates per ewe
cycling of 39 and 19% respectively. Fitting pre-flushing and joining
weights as covariates removed rearing and differential feeding effects
on those rates. Extrapolation of the data suggests that poorly-reared
ewes would ovulate similarly to well reared ewes at similar mating
weights.
Facial eczema depressed live-weight gain and had a further detrimental
effect on the probability of ewes ovulating.
