	abstract = {The original objective of a trial conducted in 3 herds of Friesian  heifers was to compare pregnancy rates obtained when each animal was  synchronised and then inseminated at about 50 h after removal of a  subcutaneous ear implant (CrestarTM) or an intravaginal device  (GenermateTM). Because most of the heifers in the CrestarTM group were  in oestrus before any of the herdmates treated with the GenermateTM  system, the CrestarTM treated heifers were inseminated at either 28 h or 50  h after implant removal. Over the 3 herds, 64\% of 153 heifers treated with Crestar were in oestrus by  28 h after implant removal compared to 7\% of their GenermateTM treated  (n=155) herdmates (P<0.01). The average pregnancy rate to first  insemination of 56.3\% was similar for both synchrony treatments, and for  the two insemination times in CrestarTM treated heifers. The earlier onset of oestrus in heifers treated using the CrestarTM system  was possibly associated either with persistent and dominant ovarian  follicles, or to the injected oestradiol valerate producing behavioural  symptoms of oestrus. Nonetheless, inseminating heifers with a shortened  interval to oestrus at 28 h rather than 50 h after implant removal may avoid  reductions in pregnancy rate which occur with inseminations made after the  end of oestrus, or with heifers which ovulate a persistent dominant follicle. },

	abstract = {Retail audit studies were undertaken in both Sydney and Melbourne to   establish benchmarks for quality at the retail level. Midloins were obtained   from ticketed carcasses at 14 retail outlets in Sydney, on 3 occasions (2x3)   during the same week in March 1994. In Melbourne, midloin samples were   obtained from non-ticketed carcasses in 38 and 40 retail outlets in June 1993   and January 1994 respectively. Using an L* value of 32 and a pH value of   5.8 as criteria of acceptability it was found that similar numbers of   unacceptable samples occurred in both cities. Using a Warner Bratzler (WB)   shear force of 5 kg as an indicator of unacceptable toughness, 15\% of   samples from Sydney were unacceptable compared to 5\% in Melbourne.   Carcass age significantly (P<0.001) influenced the WB values for Sydney   samples. When WB values were adjusted to 1 or 3 day old equivalents 27\%   and 6\% exceeded 5kg respectively. The results indicate that management   options (such as aging), and objective measurement of carcass and meat   quality can be applied to increase knowledge and improve the overall quality   of lamb and its reputation with consumers.   },
