	abstract = {Given that almost all beef carcasses intended for export from New  
Zealand are boned out into cuts in the boning room of export plants, the  
feasibility was investigated of carrying the identification of individual animals  
from the point of slaughter through to sides in the boning room and using the  
weights (percentages) of selected cuts to predict the yield of saleable meat.  A  
Ruakura beef cuts database with information from sides of 1461 bulls, 1097  
steers, 320 heifers and 329 cows, all of known breeding, was used to test the  
accuracy of beef saleable meat yield prediction from the weights of three  
hindquarter cuts removed at the same time and site in the boning room.  The  
inside round (topside), outside round (silverside) and thick flank expressed as a  
percentage of side weight were chosen for use alone and in multiple regression  
to predict the percentage of the carcass available as saleable meat.  A model  
incorporating \% inside and \% outside and their interactions with sex (bull,  
steer, heifer and cow) provided useful prediction of \% meat yield (R2 0.77,  
RSD 2.11\%) and if hot carcass weight was added to the equation the R2  
improved to 0.78 and the RSD was reduced to 2.06\%.  The sum of the inside  
and outside expressed as a percentage of side weight gave the same accuracy of  
prediction of percentage saleable meat yield as when they were treated as  
separate independent variables.  The use of thick flank gave no improvement in  
prediction.  These results should be compared with the present system where  
sex class, fat class (grade) and hot carcass weight predicted yield with an R2  
of 0.60 and an RSD of 2.80\% for the same set of data. },

	abstract = {Somatic cell counts are used widely in the dairy industry to provide information on subclinical mastitis and milk quality. The value of this information is related to the benefits that can be obtained by using the somatic cell concentration to predict the presence of mastitis, and to the reduction in somatic cell count concentration that can be achieved by selective breeding. In this study the reduction in somatic cell concentration that can be achieved by culling and breeding is calculated from data collected under New Zealand conditions. Selection against logarithm (natural log) somatic cell concentration, without any emphasis on milk production, results in an annual rate of genetic change in log cell concentration of less than 0.6\%. This represents the maximum achievable rate of 10\% on the basis of their log cell concentration alone is predicted to reduce log cell count in the next lactation by 0.05 (cell concentration change of 20 000/ml).},

	abstract = {A lean-growth index (LGI) incorporating growth rate and the proportion of that growth which is fat is calculated by first converting live-weight differences into differences in weight of lean tissue and then adjusting these values using an estimated breeding value for fat depth. The adjustment of fat depths for weight is by within-flock double-log regression or by specifying a constant exponent in the relationship between fat depth C and live weight. Simulation studies suggested that the constant-exponent method was superior for smaller groups of sheep. Improvements in LGI by selection appear more likely to arise from genetic increases in growth rate than from decreases in weight-corrected fatness, but the inclusion of fatness in the index should lead to the production of lambs that can be taken to heavier weights before becoming overfat.},

	abstract = {Ten lambs and 10 kids were offered a low quality meadow hay (7.1 gN/kg/DM) for 12 weeks. Five of each species were then reallocated to lucerne hay (23.8 gN/kg/DM) and the remainder maintained on meadow hay. Feed was offered ad libitum. Digestibility was determined at weeks, 4, 6, 10 and 16. Animals were fed at 2 h intervals prior to slaughter and the retention time of dry matter in the rumen estimated. Body energy changes were estimated by comparative slaughter. In the initial 6 weeks kids and lambs digested meadow hay to a similar extent but whereas it was maintained in kids, digestibility by lambs subsequently declined until week 16. At week 16 values for dry matter digestibility were 0.67 and 0.54 for kids and lambs, respectively. There were no significant differences in the digestibility of lucerne hay between the species nor in the voluntary intake of meadow hay or lucerne hay. Both species consumed more lucerne hay than meadow hay. Kids retained lucerne hay longer than did lambs (18.,7 h and 11.8 h, respectively) but meadow hay had a similar retention time in both species (24.7 h and 27.8 h, respectively). Water intake of lambs was approximately double that of kids. Difficulties in determining maintenance energy requirement from body weight change are discussed.},
