	abstract = {Two trials were conducted on water intake of red deer stages to provide a basis on which to determine water requirements for deer farms. In the first trial, water intake from a trough by 13 15-month-old deer stags was monitored for 16 days while they grazed dryland pasture during a spell of dry weather (March - April 1988) in Canterbury. Voluntary water intake (VWI) from the trough was 2.6 litre/hd/d and intake of water ingested in feed (40\% DM) was estimated to be 4.2 litre/hd/d, giving a total water intake (TWI) of 6.8 litre/hd/d (or 0.19 litre/kg W0.75/d). In the second trial, 12 3- to 5-year-old stags were held indoors in pens and fed (n=6) either pasture silage (27\% DM) or pellets (88\% DM) in a crossover design with Period 1 of 33 days duration and Period 2 of 25 days. VWI and DMI were monitored daily for 15 days in Period 1 and 14 days in Period 2. TWI for silage was greater than for the pellets (10.6 v 4.6 litre/hd/d, respectively) but the stags drank more water when consuming pellets. There was evidence of a linear relationship between TWI and DMI.},

	abstract = {This study was carried out to examine the efficacy and safety of an injectable copper (Cu) preparation (Coprin; Cu-EDTA, Pittman-Moore Animal Health, NZ) in deer and sheep. Treatments consisted of an injection of Coprin at three dose rates on two occasions five weeks apart. Liver biopsy samples were taken one week before and one and four weeks after each injection and 22 weeks after the second injection. Approximately 75\% of the dose was present in the livers of sheep one week after each injection. However, while over 90\% of the dose was present in the livers of deer one week after the first injection, less than 65\% of the second injected dose was present after one week. Total plasma Cu was elevated for one week after the second injection only, the increase being proportional to dose rate. Plasma activities of aspartate transaminase, gamma-glutamyl transferase and sorbitol dehydrogenase were transiently elevated after the second injection, although not sufficiently so to indicate a state of toxicity. The product was found to be effective for rapidly increasing the Cu concentration of the liver in both sheep and deer. There appeared to be no significant ill-effects in either sheep or deer at twice the recommended dose for sheep.},

	abstract = {Differences between sheep and deer in the effects of molybdenum (Mo) and sulphur (S) on copper (Cu) metabolism were investigated in two dietary experiments each using 8 animals of each species. The animals were offered a hay diet supplemented (Expt 1) to contain 3, 6, 12 or 24 mg MO/kg DM and 2.3 g S/kg DM or (Expt 2) to contain 6, 12, 24 or 48 mg Mo/kg DM and 5.3 g S/kg DM. The duration of the feeding periods was 35 and 16 days, respectively. With the low S diet (Expt 1) total plasma Cu was changed from the pre- experimental level of 0.75 to 0.63, 0.77, 0.81 and 1.03 mg/litre, respectively, in sheep and from 0.95 to 0.77, 0.79, 0.67 and 1.01 mg/litre in deer. The proportion of trichloroacetic acid (TCA) soluble/total Cu was reduced by 0.05, 0.09, 0.07 and 0.21 in sheep and by 0.01, 0.05, 0.08 and 0.11 in deer. With the high S diet (Expt 2) total plasma Cu concentration changed from 0.81 to 0.82, 0.97, 1.43 and 1.41 mg/litre in sheep and from 1.08 to 0.72, 0.96, 0.88 and 1.21 mg/litre in deer. The proportion of TCA- soluble/total Cu was reduced by 0.20, 0.50, 0.60 and 0.63 in sheep and by 0.05, 0.10, 0.23 and 0.48 in deer. This study has shown that Cu metabolism in sheep is more sensitive than in deer to increasing dietary Mo concentration. While plasma total Cu increased with increasing Mo in the diet in sheep, concentrations declined in deer. This was associated with a greater induction of insoluble Cu in plasma in sheep. In both species increased dietary S enhanced the effect of dietary Mo on Cu metabolism, but deer appeared to be more sensitive than sheep to increasing dietary S concentration.},
