	abstract = {One hundred and eighty three embryos were collected from 29 donor Merino ewes and transferred as either a single or twins to Merino (MR), Coopworth (CR) and Romney (RR) recipient dams. A total of 107 lambs were weaned from these implants. A control group (MN) of 24 naturally conceived single and twin lambs were included for comparison. Follicle fibre diameters at birth were 16.7, 17.2, 17.7 and 17.6 mm (SED 0.4) for MN, MR, CR and RR respectively; while the fibre diameter of wool samples at birth for all dam groups was 16.5 mm (SED 0.3). Follicle fibre diameters at weaning were 16.5mm, 15.9, 16.3 and 16.1 (SED 0.6) for MN, MR, CR and RR respectively while the corresponding wool FDs at weaning were 16.3 mm, 16.1, 16.0, and 16.0 (SED 0.4). Weaning weight was similar in CR and RR, while CR weaned significantly heavier lambs than Merinos (recipients or naturally bred). The results suggest that crossbred dams improve weaning weights of Merino lambs born to embryo transfer but do not affect their wool follicle character-istics.},

HF ewes were significantly (P<0.001) heavier than RC ewes for autumn live weight (8\%), winter live weight (9\%), spring live weight (7\%), greasy fleece weight (20\%) and clean fleece weight (19\%). Small but significant (P<0.01) flock differences were found for fibre diameter and yellowness. HF fleeces were coarser and more yellow than RC fleeces. HF ewes were significantly (P<0.01) higher than RC for ovulation rate (1.80 vs 1.73 SED 0.03), number of lambs born/ewes lambed (1.63 vs 1.56 SED 0.02), and number of multiple births/ewes lambed (60\% vs 54\% SED 2\%), but lower (P<0.01) for number of lambs weaned/lambs born (0.84 vs 0.88 SED 0.01). The results indicate that single trait selection for fleece weight enhances greasy and clean fleece weights, live weight and ovulation rate, with an associated increase in FD and yellowness of their fleeces. },

Shoulder wool strip samples were collected at 3, 9, 12 months of age, two-tooth and as 2 year old ewes. The wool characteristics of yield, fibre diameter, resistance to compression and tristimulus colours were measured. No significant sire effect was found for tristimulus Y values at any sampling interval. A significant (P<0.05) tristimulus Y-Z difference was found for two tooth fleeces in progeny of Yellow sires compared with Bright (5.3 vs. 4.4 SED 0.4). Belly and back site wool was significantly (P<0.05) more yellow (Y-Z 7.8 and 6.1) than other body sites, belly wool was also lower (P<0.05) for brightness (Y 47.9) than other sites. The most significant source of variation in tristimulus Y and Y-Z values was contributed by body regions of fleece, emphasising the importance of effective skirting of fleeces. },

The ovulation rate (combining subgroups with the same Inverdale genotype) was significantly (P<0.05) higher for I+ (2.3) than ++ (1.5) progeny (SED: 0.3).

	abstract = {Wool production characteristics were investigated for fine-wool sheep of  
different genotypes at Nanshan Stud Farm, Xinjian Uygur Autonomous  
Region, China. 
 
Four main sets of data were available.  The 1985 ewes were mixed-age Xinjian  
Finewool (XF).  The 1986 ewe and ram hoggets were XF, F1 Australian Merino  
(AM) x XF and F1 Chinese Merino (CM) x XF.  The 1987 ewes included CM,  
mixed-age XF, F1 AM x XF 2 year olds and F1 AM x XF hoggets.  The 1987  
rams included AM, CM and mixed-age XF.  Observations were made and  
samples collected at shearing in June.  Measured traits included: -body weight  
(BW); greasy fleece weight (GFW); clean yield (CY); clean fleece weight  
(CFW); fibre diameter (FD); crimp frequency (CF); staple length (SL): colour  
(CL); weathered tip (WT); dirt (DT). dirt penetration (DP): suint (SU, and wax  
(WX). 
 
Significant differences (P<0.05)) occurred between hogget genotype and  
between sexes.  AM x XF hoggets produced more wool than CM x XF, or XF,  
but there were no differences in BW.  Ewe and ram hoggets had similar BW{\textquoteright}s,  
but ewe hoggets produced more wool of lower FD with greater SL and WT.  In  
the XF ewes, as age increased there were significant (P<0.05) changes in GFW,  
CY, CFW, SL and WX.  Clean fleece production of 3-6 year old XF ewes  
declined by 0.17 kg/yr and SL by 0.33 cm/yr.  In the XF rams, there were  
significant (P<0.05) increases in BW and DT with age, whilst wool production  
increased to 3-4 years and then declined.  There were significant (P<0.05)  
differences between years in GFW, FD, SL, WT, DP, DT, WX and SU in  
hoggets, and CY, CFW, FD and SL in mature ewes.  The 5 body sites of XF  
ewes in 1985 had significant (P<0.05) differences in fleece traits for FD, SL  
and CL.  There were significant (P<0.001) correlations between traits for  
pooled data from all genotypes, ages, sexes, years and sampling sites.  Negative  
correlations included WX with WT, DP, and DT; and DT with CY; whilst DP  
was positively correlated with WT. 
 
These results have implications for future sheep breeding and wool technology  
research, and development of programmes for improved clean wool production  
and quality in China. },

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.},

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.},

	abstract = {Masked by the short-term influences of under or over-production   at national level, concerns about the quality and hygiene of animal   products and fears regarding dietary influences on human health, long-   term projections of what will be expected of the pastoral animal   industries are difficult to make. Concerns about the welfare of animals   in intensive systems coupled with the political changes taking place in   Russia and Eastern Europe are likely to swing animal production more   towards pastoral systems. The removal of large quantities of fat from   the food chain is likely to become a permanent feature. So too is the   trend for a more even flow of high-quality products on to the market.   In meeting these goals the role of the current biotechnological   revolution, both directly in primary animal production, and indirectly   through its contribution to the animal-product and food-processing   industries, will be essential. We can not afford intellectual   scientific complacency in a world where famine could, however remotely,   become a truly global phenomenon. It is against this background that   those aspects of the pastoral animal industries that currently limit   production are viewed and the opportunities for implementing new   technologies outlined.     },

	abstract = {Dairy farmers made management decisions each season about which cow to replace. At present dairy farmers can use the production index. The production index is an historical measurement of a cow{\textquoteright}s milkfat production ranking, free from the influences of herd environment, age, stage of lactation and herd genetic level. A dynamic programming method is outlined which incorporates genetic, reproductive and economic information. This method ranks cows on their annualised present value. A sensitivity analysis was undertaken and the effects of the changes in the different economic parameters are discussed. The optimal cow rankings produced by the dynamic programming method were shown to be robust to changes in milkfat, manufacturing beef and heifer replacement prices and interest rate.},

	abstract = {Oestrus synchronisation in hoggets was compared using either polyurethane sponges containing progestagen or 9 mm diameter silicone elastomer CIDRs (controlled internal drug releasers) in 600 hoggets in 3 trials. CIDRs and sponges were removed after 12 days in late May and 200 IU PMSG given to hoggets in 2 of the trials. Hoggets in the third trial received 0 or 300 IU PMSG. Half of the hoggets were shorn 1 month prior to the 4-day joining with entire rams. The loss rate of CIDRs and sponges was low (2\%). No hoggets mated in the first 24 hours after removal and most matings occurred during the second day. During the peak of mating, more CIDR-treated hoggets appeared to mate in 2 trials, but fewer in the third (28 v 44\% P<0.01). By the end of the entire joining, there was little difference in total mated. Treatment with CIDRs or sponges did not affect ovarian activity. Pregnancy rates were unaffected by method of synchronisation in 2 trials and improved by CIDRs in the third (38 v 20\% P<0.05). Shearing generally had no effect on reproductive performance. PMSG improve oestrous and ovarian activity, but did not affect pregnancy rate. CIDRs were an effective substitute for sponges in achieving synchronised pregnancies in hoggets. Low pregnancy rates limited the ability to fully capitalise on the benefits of synchronisation.},

	abstract = {Previous work showed that nutrition during pregnancy substantially affected ewe live weight, but that subsequent effects on ewe and lamb survival and weaning weights were small. However, farm advisers have suggested that industry ewes suffer more weight loss than in the above trials with serious consequences for ewe and lamb survival. These problems were investigated in a trial involving 2 levels of nutrition in mid-pregnancy followed by 3 levels of nutrition in late pregnancy. Average conceptus-free live weights of the 6 groups at lambing ranged from 47.6 to 38.1 kg. The ewes had weighed 53 kg at the start of the trial. Ewes severely under-nourished throughout had an 86\% survival during the trial period compared with 94\% for the 5 better-fed groups. A line of ewes within the severely under-nourished group had, however, only 80\% survival. There was a decline in the percentage of ewes lambing due to very nutrition in mid-pregnancy (78 v 85\%). Similarly, lambing percentage of those ewes lambing was affected (126 v 142\%). There was some effect on twin lamb survival. Birth weight, particularly twin lambs, was reduced by low nutrition but there was no effect on weaning weight.},
