	abstract = {Two trials were conducted to define the variation in concentrations of b-lactoglobulin (b-LG) in bovine milk following different milking intervals. In the first, milk samples were collected from three herds of 20 cows. At the time of sampling in early summer, one herd was in each of early, mid and late lactation (30, 120 and 210 days post calving, respectively). Average b-LG concentrations were 41, 37 and 50\% higher (p<0.05) after a 16h than 8h milking interval for early, mid and late lactation, respectively. In the second trial, bulk milk was sampled from four herds of 12 cows. All cows were at the same stage of lactation and the milking interval was 16:8h. Samples were collected on three separate occasions when cows were on unrestricted pasture intake and once when intake was restricted by 50\%. On unrestricted pasture intake, concentrations of b-LG were 11\% higher in milk collected after 16h than 8h milking interval, whilst on restricted intake, concentrations were 44\% higher. There were no differences in concentrations of a-lactalbumin (a-LA). Both trials show a significant difference in b-LG levels in milk collected after 16h versus 8h milking interval, although only 71\% of all samples collected in the first trial exhibited this difference and it was less in the second trial using bulk milk. },

	abstract = {Milk production by dairy cows and yield of the compo-nents, fat, protein and lactose are closely related to nutritional intake. The individual proteins in milk respond differently to a change in nutritional status, giving rise to significant differ-ences in milk protein composition (DePeeters and Cant, 1992). For instance, Gray and Mackenzie (1987) noted a decrease in α-lactalbumin and increase in serum-derived proteins, serum albumin and immunoglobulin, in animals on restricted pasture for 10 days. Although β-lactoglobulin concentration decreased, the response was not significant. Treatment of concentrate-fed dairy cows with a single injection of atropine caused a similar, though temporary, decrease in milk yield, total protein and α-lactalbumin content of milk (Roets and Peeters, 1981). Changes in other milk proteins were not evaluated. The observed responses arise from the ability of atropine to rapidly and specifically depress plasma amino acids used for milk protein synthesis and provide a means of experimentally manipulat-ing supply of substrates for milk protein synthesis. The present study was designed to evaluate the use of atropine in pasture-fed cows.},

	abstract = {The use of chickens for the production of highly specific antibodies  
to mammalian proteins offers a number of advantages over more conventional  
methods.  Antibody responses to IGFBP-3 immunogen were apparent in the  
serum of chickens after only two inoculations with low levels of the  
immunogen.  These specific antibodies subsequently appeared in the chicken  
egg yolk at levels of approximately 40\% of those estimated in serum. 
 
A simple, rapid and reproducible two step method for the extraction and  
purification of the immunoglobulin fraction from egg yolk using octanoic acid  
is described.  Relatively large quantities of specific antibodies can be  
obtained by these procedures.  Egg yolk antibodies generated in this study  
will be used to develop an ELISA for measuring levels of IGFBP-3 in plasma  
and other body fluids.  This approach is designed to overcome some of the  
difficulties associated with the use of ligand blotting analysis to quantify  
IGFBPs. },

	abstract = {Inherited protein variation in the blood of domestic species can provide the means to resolve cases of uncertain parentage. In red deer, protein variation has been described from natural populations in Europe, although the inheritance of this variation has not been verified using family data. This paper examines protein variation in the blood of New Zealand farmed red deer and tests the inheritance of each protein variant using family data from 46 matings. The 2 most variable proteins reported in European deer, transferrin and isocitrate dehydrogenase, were also variable in New Zealand farmed deer. The inheritance of variation in each of these proteins was consistent with co-dominant Mendelian inheritance at a single locus. In addition variation was found in plasma proteins in the postalbumins and the gamma-globulins. Variation in the postalbumins was consistent with co- dominant Mendelian inheritance at a single locus while variation in the gamma-globulins did not appear to be inherited. The inherited protein variants identified in red deer provide a blood test which detected 70\% of the possible mismatches between parents and calves in the sample of 46 matings.},

	abstract = {Normal calvings among 527 cows in a Ruakura Research Station herd (No.1) were not evenly distributed throughout the 24 hours. They were most frequent in the early morning (0100 h to 0600 h, 39\%) and afternoon (1300 h to 1900 h, 29\%). This diurnal pattern was consistent between years. Altering feeding time from 0700 h to either 1600 h or 1900 h did not increase the frequency of daylight calvings. Feeding at 1900 h did produce 2 periods of intensive grazing each 24 h instead of only one. If a beneficial change in calving pattern is to be produced, it may be necessary to disrupt the period when most cows rest (0100 h to 0600 h) by feeding at around 0300 h.},

The advantages of extended data sharing in the animal based industries of New Zealand include the possibility of conducting research studies previously considered not feasible because of the resources required to collect and collate the needed data. With the sharing of information between farms, Government agencies, research institutions, servicing organisations and advisory services, it is possible to foresee research studies of considerable benefit to the primary industries in New Zealand. This paper will examine the concept of shared information and provide illustrations from the New Zealand Industry of the research potential.},
