	abstract = {The objective of this research was to identify metabolites produced by commensal bacteria that enhance the integrity of the gastrointestinal barrier (GIB). The integrity of the GIB is mainly determined by the complexity of interactions between tight junctions of opposing epithelial cells of the GI wall. This was measured using an in vitrobioassay, consisting of a monolayer of intestinal epithelial cells grown on a membrane. The trans-epithelial electrical resistance (TEER) across this monolayer was measured to determine the strength of the tight junctions. Preliminary results showed that a commercial probiotic product caused an increase in TEER across non-differentiated and differentiated monolayers by 178 {\textpm} 61\% and 40 {\textpm} 9\%, respectively. The maximum increases in TEER obtained with conditioned media fractions (media fractions containing components secreted by the probioticproduct) was between 23 {\textpm} 6\% and 43 {\textpm} 4\%. The conditioned media fraction containing components less than 3 kDa accounted for the total activity of the whole conditioned media. Metabolite profiling ofactive conditioned media compared to inactive conditioned media using fast-LCMSMS identified numerousmetabolites that may be responsible for this positive effect. Future work will isolate the candidate metabolites and screen them for GIB enhancing activity both in vitroand in vivo.},

	abstract = {A dynamical model describing the evolution of muscle, viscera and fat in response to different levels of energy intake over time in sheep is presented. The model shows responses consistent with observations of compensatory growth in sheep and cattle over a range of energy intake levels. Model parameters are derived from data measured by Ferrell et al., (1986) to investigate compensatory growth in lambs. The model is shown to generally reproduce the behaviour of the muscle, viscera and fat components of the lambs in this trial. The utility of the model for designing optimal nutritional management strategies for raising animals for slaughter is discussed, as well as the potential of the model to advance the understanding of animal nutrition by investigating different functional forms for relationships such as maintenance requirements. },

	abstract = {Two groups of 33 Angus steers aged 270 days and weighing 179 {\textpm} 2.1 kg were allocated after weaning to 2 pasture regimes designed for high (H) and low (L) mean Liveweight. When the treatments finished after 138 days liveweights were 242 {\textpm} 3.7 kg (H) and 218 {\textpm} 3.7 kg (L). Both H and L groups were then grazed together on pasture until slaughter at 30 months of age. At slaughter fat depth at the 12th rib, weight of kidney and channel fat, ribeye area, and the trimmed fat, bone and lean (90\% visual lean) were measured from the right side of the carcass. Carcass weight was the same for both treatment groups (258 {\textpm} 2.5 kg). The L group had faster liveweight gain than the H group for 283 days after treatment, but not thereafter. Steers from the L treatment had more kidney and channel fat (P<0.02). A significant (P<0.01) regression coefficient of 0.05 {\textpm} 0.019 for carcass weight on kidney and channel fat weight existed for steers in the H group, but not the L group. Rate of live weight gain before weaning was significantly (P<0.01) related to the weight of trimmed bone and lean at slaughter. Differences between animals in live weight gain at the end of the treatment period affected the weight of kidney and channel fat in the L group (P<0.01), and the weight of trimmed fat in the L group (P<0.05). These results are discussed in context of effects of growth rate on tissue development in cattle. },

	abstract = {Deer are unique among New Zealand{\textquoteright}s farmed ruminants in the  existence of hybridising species and subspecies which exhibit major  differences in physiology and production traits. We used protein  electrophoresis to examine genetic differences between two farmed deer  species with fertile hybrids:red deer (Cervus elaphus) and Pere  David{\textquoteright}s deer (Elaphurus davidianus<?I>) (in both species 2n=68).  Fixed differences between the species were found for 19 proteins. A  further 3 proteins were polymorphic in red deer but not in Pere David{\textquoteright}s  deer. Using the present techniques, segregation of 17 of the protein  differences between the species could be confirmed in a backcross  pedigree to red deer. The large number of genetic markers segregating  in backcross hybrids make them an excellent resource for gene linkage  mapping among genetic markers and for experiments which examine the  relationship between genetic markers and quantitative traits.  },
