	abstract = {Production data was collected from 400 mix4ded-age breeding ewes on each of 4 farms in the Kaiwaka area for 3 years between 1982 and 1986. Half of the ewes on each farm were shorn once yearly and half twice yearly. Each farm had a different time schedule. The once-yearly shorn group were shorn in either February, June, October or November and the twice-yearly shorn group in October and February, December and June, February and October or May and November respectively. Ewes second shorn in February were heavier at main shearing in October than twice-shorn ewes. Ewe live weight on the other 3 farms was unaffected by shearing treatment. Total clean wool production of twice shorn ewes was greater than once-shorn ewes on all farms with the effect being greater following second shearing in May and October. Mean staple length of the lines of fleece wool reflected the actual interval between shearings and the seasonal wool growth cycle. Mean fibre diameter was a direct reflection of the seasonal wool growth cycle. Once-shorn wools were more discoloured than twice-shorn wools. Wools shorn between May and October were less discoloured than wools shorn between November and February. Frequency of shearing did not affect ewe survival, reproduction rate or lamb weaning weight. Average net wool returns were greater for once-shorn ewes on all farms.},

Hogget lambs born during the 1981 and 1982 lambings were used to study the timing, magnitude and causes of lamb mortality. Mean mortality to weaning were 33\% and 28\% in each year. The distribution of deaths was similar in each of the periods: at birth, born alive but died by day 3 and died between day 4 and docking. Dystocia was the single largest cause of deaths to day 3 accounting for about 13 lamb/100 lambs born. Birth weight was an important factor in lamb deaths with an optimum range of 3.3 to 4.1 kg for minimum mortality.},

	abstract = {The following farmer observations are based on limited numbers and are really a plea for more accurate work to be done. Loss from dags is difficult to cost but nationally it probably runs into millions in devalued wool and extra labour. On my own farm the direct loss is estimated to be about 63 cents/stock unit/annum. To reduce this loss I have looked at the following practices: 1. Breeding, limited observations - nil results. 2. Drenching. In two-tooths a drench pretupping reduced dags 44\% in a 3 month period. 3. Docking tails longer was inconclusive, possibly due to a limited difference between {\textquoteright}long{\textquoteright} and {\textquoteright}short{\textquoteright} tails. 4. Mules operation. Result a 50\% reducing between January and May. Mulesed sheep are easier to crutch by hand or machine. Sheep were apparently not knocked about by the operation. Although gory, mulesing is preferable to flystrike in terms of suffering. Uninformed and emotional public opinion is a problem. The greatest benefit of dag control or elimination may come from reduced flystrike.},

In their first and second years respectively in the ova transfer programme, 39\% and 32\% of donor ewes failed to have any progeny by ova transfer, and 38\% and 44\% failed to lamb themselves while the mean number of lambs tailed per donor at joining was 2.68 and 2.21.

High lamb mortality rates (27\% and 32\% of lambs born) resulted in 1.58 and 1.64 lambs tailed/ewe/annum. About 40\% of ewes failed to reach the objective of at least 2 live lambs/ewe/annum in both programmes.},

	abstract = {Twelve ram lambs bred for resistance or susceptibility to sporidesmin dosing were operated on under general anaesthetic and T-way catheters inserted into the common bile duct to facilitate collection of bile. After a recovery period of 14 days the animals were given an oral dose of sporidesmin at a rate of 0.08 mg/kg/d over 3 consecutive days. A trace amount of 35S-labelled sporidesmin was also given on the first and third day of dosing to allow quantitation of sporidesmin appearing in the bile fluid. Bile samples were collected at 0.5 to 1 hourly intervals for 24 hours after the first and third dosing. Results showed bile concentrations of sporidesmin increasing to a maximum in 1 to 3 hours and then declining over the following 20 hours. There was considerable individual variation among animals in the pattern of uptake and in the maximal concentration reached after dosing. In some animals there was a marked increase in biliary sporidesmin from the first to the third oral dosing while other animals showed little observed increase at these times. A positive correlation (P<0.05) was found between liver- damage score at slaughter and maximum sporidesmin concentration in bile after the third but not the first oral dosing. These findings raise the possibility that an initial or {\textquoteright}potentiating{\textquoteright} dose of sporidesmin may be required before {\textquoteright}susceptibility{\textquoteright} or {\textquoteright} resistance{\textquoteright} to facial eczema is expressed.},

	abstract = {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.},

	abstract = {The basic aim of selection in flocks in the 150 to 200\% lamb drop range remains unchanged, namely to breed sheep of sound physical type and with the genetic potential to give maximum net profits per hectare from sales of meat and wool. However at these fertility levels the main thrust of selection moves off fertility due to the doubtful benefit of large numbers of triplets under commercial farm conditions. More emphasis can profitably be placed on milking ability as expressed by weaning weight. This has major implications in ensuring quick seasonal disposal of lambs to reduce the pressure on stocking rate brought about by high fertility. Also fleece weight gains in importance as increases in wool production do not involve increased stocking rate. In high fertility flocks health and behaviour traits such as free lambing, mothering ability and resistance to foot problems are of even greater importance. Overall, a very important factor to be considered in future selection in high fertility flocks is that per head gains in production be made while holding ewe body weights, i.e. an emphasis on efficiency for best per hectare results.},
