	abstract = {Superovulatory response to a single injection of PMSG (300ui) and of oFSH (3.6mg Ovagen{\textregistered}) given at either day 11, 16 or 18 after ovulation and a 7 day CIDR-G{\textregistered} or 30mg FGA sponge treatment was studied in Merino ewes. Follicle populations just before the administration of exogenous gonadotrophin and total ovarian response to treatment at day 5 of the next cycle were determined using transrectal ultrasound and laparoscopy respectively. The stage of the cycle had no significant effect on follicle population at the time of superovulation treatment or superovulatory response. Compared to FGA sponges, CIDR-G treatment reduced the number of 4-5mm follicles (2.83 {\textpm} 0.89 vs. 1.0 {\textpm} 0.3, P<0.05), the incidence of ewes with follicles >=4mm (100\% vs. 50\%, P<0.05) and tended to increase superovulatory response (6.3 {\textpm} 3.7 vs. 10.3 {\textpm} 3.5, P<0.1). Ewes were classified according to the absence (n=4) and the presence (n=17) of a large follicle (>/=4mm diameter) at the time of superovulation treatment. Ewes without a large follicle had higher superovulatory response (13.8 {\textpm} 2.7 vs. 5.0 {\textpm} 1.3, P<0.05) and tended to have lower numbers of anovulatory follicles (0.5 {\textpm} 0.7 vs. 1.8 {\textpm} 0.3, P<0.1). These results suggest that the presence of a large follicle at the time of exogenous gonadotrophin treatment reduces superovulatory response in ewes and that the incidence of such follicles may be reduced by the use of a 7 day CIDR-G treatment. },

	abstract = {Marshall Romney ewes had higher ovulation rates and percentage births than control Romney ewes. These differences were accounted for by the higher live weights of Marshall Romney ewes. Differential grazing in 1979 produced ewes with different condition scores and live weight but the same body size. Ovulation rates were higher in the heavier ewes with the higher condition score. Body size and condition score contributed approximately equally to the variation in the live weight and both accounted for a significant proportion of variation in ovulation rate. However live weight accounted for more of the variation in ovulation rate than body size and/or condition score.},

	abstract = {The fat thickness over the 12th rib was measured ultrasonically on 41 Coopworth ram lambs (7 months of age, 34 to 57 kg live weight). Four of the 7 fattest and 4 of the 7 leanest were selected on the basis of their deviations from the overall fat thickness - live-weight relationship. Ten to 12 male progeny of each of these rams generated from Perendale ewes were slaughtered at 4 to 7 months of age and 4 parameters of carcass fatness measured. The difference between the progeny of the 4 lean sires and that of the 4 fat sires was significant for 2 fat measurements, namely C (P<0.05) the backfat thickness over the 12th rib, and S2 (P<0.01) a fat depth in the shoulder region. Differences in GR and total chemical fat failed to reach significance. The data indicate that selection of sires on the basis of backfat thickness could be an effective means of reducing carcass fat thickness in lambs.},
