	abstract = {The Wairunga flock was established in 1956. It has since been  selected for production traits and, recently, also for {\textquoteright}disease{\textquoteright} traits  (resistance to footrot, dags and internal parasites). Records of  weaning weight, autumn weight, winter weight, faecal egg count (FEC) and  fleece weight have been collected on ewe and ram lambs from the 1987-  born crop onwards, in a management programme which involved withholding  anthelmintic drench for a monitored period in autumn. Dag scores have  also been taken at the time of faecal sampling from the 1988-born crop  onwards. Experiences already show that there is keen interest from ram  buyer clients in 2-tooth rams that have grown without a drench. Results  show significant potential savings in numbers of drenches on weaned  lambs, and large differences among sire groups in the parasite  susceptibility of progeny groups. Because of the need to withhold  drenches, a major change in the whole concept of ram breeding and  performance testing will be required by ram breeders and their clients  before much progress can be made in breeding for resistance to internal  parasites.  },

	abstract = {An experiment was conducted to investigate the effect of   nutritional status on fibre quality from Angora goats during spring.   Two groups of 28 non-pregnant Angora does were grazed on ryegrass/white   clover pasture at one of two pasture allowances; 1.0 kg and >4kg DM   /head/day (low and high respectively) for twelve weeks during spring.   Groups were balanced for live weight, age, fibre diameter, medullation   and kemp measurements and genetic background. Live weight and fibre   quality (fibre diameter, \% medullaltion and \% kemp) were measured at the   start, after 6 weeks and at the end of the experiment. Mean live weight   of does at the start of the experiment was 22.6 + 0.20 kg and after 12   weeks 30.9 and 25.2; sed 0.63kg for high and low allowance respectively.   Neither mean fibre diameter (35.2 vs 34.1; sed 0.66 microns) nor   medullation (5.38 vs 6.51;s ed 53\%), was affected by pasture allowance   over the experiment (high and low allowance respectively). However,   after 12 weeks, there was a trend for \% kemp measured in the fleece in   does on high pasture allowance to be higher than in does on low   allowance (8.16 vs 6.52; sed 1.04\%). All does were fibre tested again in   March 1989 after grazing at a common allowance, but differences in   fibre characteristics between the previous spring pasture allowances   treatments were small. It appears that doe nutrition during spring can   influence the kemp content in the Angora fleece. The mechanism of this   effect is, however, not known.    },

	abstract = {Lambs in pens were infused duodenally with increasing amounts of   casein or a mixture of four essential amino acids (EAA) to examine   effects upon N retention. Eight Dorset Down x Coopworth lambs (39+/-1.1   kg) each fitted with rumen and duodenal cannulae were housed indoors and   offered freshly cut ryegrass/white clover pasture at a rate of 470g   fresh herbage/kgW0.75(MW)/d. The metabolizable energy intake from   herbage was approximately 870 kJ/kg(MW)/d.     Experimental treatments were duodenal infusions of water (control), 3,   6, 9 and 12g casein/kgMW/d and three levels of a mixture of AA   (methionine, lysine, histidine and arginine) in amounts equivalent to   the supply of these AA in 3, 6 and 9g casein. Treatments were allocated   in an 8 x 8 latin square design.     Duodenal non-ammonia N (NAN) flow indicated that 33\% of forage protein N   intake was lost across the rumen, the mean flow being 1.46gNAN/kgMW/d.   Infusions of casein resulted in significant linear increases (P<0.01) in   N balance up to 6g casein/kgMW/d, the casein N supply at this level   being equal to the N lost across the rumen from the basal forage. The   increase in N balance with infusion of 6g casein was equivalent to an   additional 96\% of the N balance observed with the control treatment. No   further significant change in N balance was observed with casein   infusions greater than 6g/kg/MW/d. A small non-significant response to   infusions of 4 AA was observed indicating that these 4 essential AA were   not solely responsible for the response. These results indicate that   liveweight gain responses can be expected if the losses of protein that   occur in the rumen of lambs grazing temperate pastures can be reduced.    },

	abstract = {The necessity to identify and utilize superior fibre producing goats has led to the demand for artificial breeding techniques to be developed within New Zealand. Particular emphasis has been placed on cervical insemination by Ambreed as it is seen as the most cost efficient methods, especially at a commercial level. Bucks have been selected on individual fleece data and stood on licensed artificial insemination centres at Cambridge and Kaiapoi. A total of 50 bucks have been trained for semen collection, with the training period varying from 5 minutes to 2 weeks. Collection from some individuals began as early as December, and continued until August. All semen used was frozen in a Tris-based egg yolk/glycerol diluent. Semen quality has been determined by post-freeze motility using a 2 sec photomicroscopic technique. Training courses lasting for 3 d have been held to instruct both visiting technicians and owner/operator type inseminators. In combination with Ambreed technicians operating directly from Cambridge Centre, approximately 15,000 goats were inseminated during the 1987 autumn period. Kidding data are currently being analysed and indications of pregnancy rate from non-return rates are currently in the 50-55\% range.},

The targets were to purchase bulls during October or November at 85 to 100 kg live weight and to grow them to between 420 and 440 kg live weight by 1 December the following year. Using average pasture growth rate data, a simple feed budget model predicted mean pasture cover targets from April to December required to achieve the live weight targets. Grazing plans were designed and regularly reviewed to test the validity of using mean pasture cover as an indicator of successful management.},
