	abstract = {To determine the incidence of high ultimate pH (pHu) across farms 967 cattle were involved in a survey which showed 3\% of Angus, 21\% of Simmental cross and 60\% of the Friesians steers had an pHu above the acceptable maximum of 5.8. In further work, muscle (longissimus dorsi) biopsies samples were taken from 60 two-year-old Angus, Simmental cross and Friesian steers (n = 20 per breed) in late November and assayed for glycogen concentration and enzyme concentrations that indicated muscle fibre type. Behaviour measurements were made on all animals before slaughter. Individual measurements of carcass characteristics were made 22-24 hours after slaughter, including carcass weight, pHu, meat colour score, and fat depth (GR). Only one carcass had a pHu above 5.8 and there was no pHu difference between breeds (5.53, 5.55, and 5.58 for Angus, Simmental cross, and Friesian, respectively). There was no difference between breeds in the glycogen concentration in the muscle, although there were differences in enzyme concentrations that suggested differences between breeds in the proportion of the three muscle fibre types. Flight distance were small (4-7 m) but longer for Friesian than Simmental cross steers. There were no relationships between meat pHu and flight distance, glycogen concentration or muscle enzyme concentrations. Breed did not appear to effect pHu or muscle glycogen concentration. },

	abstract = {Two trials were conducted to assess the effect of kiwifruit vinegar on a number of production parameters in sheep. Trial A evaluated the effect of kiwifruit vinegar (8.2g/100ml, as acetic acid) on lamb liveweight gain, fleece production (midside growth rate, yield and colour), and internal parasite burdens. Trial B evaluated the effect of kiwifruit vinegar on two-tooth liveweight change prior to mating, and subsequent fertility. In trial A 138 ewe lambs were randomly assigned to one of four treatment groups: i) "Extender 100" Albendazole drench capsule + 10 ml vinegar, ii) "Extender 100" Albendazole drench capsule only; iii) normal drenching (trigger level 1500 epg) + 10 ml vinegar, iv) normal drenching. The only trait for which there was strong evidence of an effect was wool yield which decreased in response to kiwifruit vinegar. Vinegar treated lambs tended to have reduced faecal egg counts during the period of the trial. In trial B 140 two-tooth ewes were randomly assigned to one of two treatment groups: i) 15 ml vinegar administered at 12, 8, 4 and 1 weeks prior to mating; ii) control. Reproductive status was assessed by ultrasound 38 days after removal of the ram. No significant differences were found in liveweight or in reproductive status between the group groups. Evidence from these two trials would suggest that any effect of kiwifruit vinegar on performance traits in sheep is small and not necessarily beneficial.},

	abstract = {This study investigated the effect of a progesterone containing intravaginal CIDR (Controlled Internal Drug Releasing) device on plasma progesterone and luteinizing hormone (LH) concentrations during 14-day device insertion and the subsequent oestrous cycle of fallow deer (Dama dama). Blood samples were collected from 4 entire does at 20 minute intervals for periods of 8-12h on three occasions following device insertion (i.e. insertion, mid-treatment and withdrawal) and on Days 0, 5, 12 and 19 of the subsequent oestrous cycle. Plasma was analysed for progesterone and LH concentrations by radioimmunoassay. Plasma progesterone values were elevated (>6 ng/ml) and LH values reduced (<1 ng/ml) during device insertion relative to pre-insertion values. Plasma LH concentrations were highest on Day 0 of the oestrous cycle, with a marked increase in the pulse amplitude.  One doe exhibited a pre-ovulatory LH surge. Plasma progesterone increased from <0.5 ng/ml on Day 0 to 1.5-4.2 ng/ml on Day 12 (luteal phase) and high amplitude progesterone pulses were exhibited by all does on Day 19 (onset of luteolysis). The study has demonstrated that CIDR devices deliver sufficient progesterone to inhibit ovulation and the declining plasma LH concentrations during device insertion support a hypothesis of negative feedback by progesterone on LH secretion.},

The first was from 16 October 1990 to 21 December 1990 while the second continued until 29 August 1991. Treatment period 1 generated significant differences in liveweight (P<0.001) between all groups and thereafter the sheep were grazed in 2 larger mobs consisting of groups 1-3 and 4 and 5.
