	abstract = {As genetics and management practices have improved within the Australian lamb industry, the weight of lamb carcases has in-creased. Yet, the demographics of lamb consumers and their consumption patterns have changed, as household size has become smaller. Consequently, the traditional lamb cuts have less appeal to consumers from smaller households when taken from heavy carcases (>25kg). Therefore, research has been conducted to determine the potential for fabricating new cuts from heavier lamb carcases, determine the nutritional composition of new cuts and examine the impact of increasing carcase weight and fat depths on the time and labour required to process larger carcases into smaller cuts. Development of an information matrix of available lamb data on the eating and nutritional qualities and contribution to total carcase yield highlighted the potential to create further val-ue-added cuts from the forequarter and leg. However, the time taken to fabricate these increasingly value-added cuts from heavier carcases increased with carcase weight (0.44 minutes/kg (s.e. = 0.065) and changes to the saleable meat yield resulted in increased average product prices. Based on the program, a new cut called the Compact Shoulder Roast was developed to provide an option for retailers when processing heavy carcases. This paper outlines some of the outcomes of this program. },

	abstract = {The Information Nucleus flock (INF) is the central focus of the Co-operative Research Centre (CRC) for Sheep Industry Innovation. It is made up of eight sheep flocks across Australia that are genetically linked by the use of common sires. The objective of the INF is to measure a range of biological and production parameters and to produce heritability estimates and genetic correlations for a range of new traits. Approximately 100 sires are mated annually by artificial insemination to 5,000 ewes across the sites. Sires from various breeds are joined to Merino and crossbred ewes. Each year 2,000 progeny are evaluated for a wide range of meat production and consumer-relevant traits. Some of these traits are new and novel, such as the content of iron, zinc and omega-3 fatty acids. Their measurement is designed to ensure lamb maintains its marketing edge as a healthy, nutritious meat so that it is the consumer{\textquoteright}s preferred choice of meat. This paper will provide an overview of the program and highlight specific areas that are novel with respect to sheep meat. },

	abstract = {Triplets occur when lambing percentages exceed 130\%. When triplets are left with their dam, survival is often less than 75\%. Artificial rearing of onelamb from each set of triplets offers the chance to increase survival rates. But experience to date has frequently resulted in death rates of10\% to 30\% of lambs. On the author{\textquoteright}s farm about 100 sets of triplets are born each year. In 2002 an artificial rearing system was put in place based on the Poukawa system. The smallesttriplet from each set was removed for artificial rearing. In 2002 and 2003, when lambs were 3 to 5 weeks old, up to 25\% died. A worldwide information search suggested that the disorder was possibly abomasal bloat. A Norwegian method of preparing {\textquotedblleft}soured{\textquotedblright} milk replacer that had been demonstrated to limit abomasal bloat was adapted for New Zealand conditions. Lambs are fed cow colostrum for two days, followed by ad lib. cold {\textquotedblleft}soured{\textquotedblright} whole milk replacer and ad lib. meal. In 2004 and 2005, there have been no deaths due to abomasal bloat. Total deaths from 199 lambs have been 9. Live weight gains of the lambs have been 220-250 grams per day till 8 weeks.},

	abstract = {This paper discusses recent work by the authors which has investigated the nutritional regulation of glycogenconcentration in skeletal muscle of sheep and cattle. Several experiments are summarised which show a clear relationshipbetween the level of glycogen in muscle and the intake of metabolisable energy. This translates into strong seasonal effectson the level of muscle glycogen in pasture fed cattle that correlate with live weight change. The clear message is thatanimals destined for slaughter should be on a high plane of nutrition as this will contribute to an increased level of muscleglycogen at slaughter and so help alleviate the problem of dark cutting meat. Acute regulation of glycogen is moreproblematical since the rate of glycogen repletion in skeletal muscle is relatively slow and the scope for rapid dietarychange in ruminants is constrained by the need to allow rumen adaptation to high starch/sugar diets. However the suddenintroduction of a high energy diet (based on cereal grain) in the presence of a {\textquoteleft}rumen modifier{\textquoteright} to reduce ruminal acidosiscan increase muscle glycogen concentration within 1 week of feeding. The ability to further modify glycogen level inskeletal muscle using carbohydrate and electrolyte products is discussed. In particular the possibility of using oral glycerol/propylene glycol as a means for increasing blood glucose and so glycogen synthesis is proposed. Experiments to examine the effectiveness of MgO as a means for reducing the stress response are also discussed.},
