	abstract = {The sexual behaviour of alpacas joined under a selective  breeding programme was recorded to assess performance and to examine  ways of providing optimal conditions for mating. Groups of 4 females  and 1 male were joined in paddocks for 5 days (3 groups) or in pens for  3.5 hours on 2 consecutive mornings (3 groups). Sexual activity was  more variable in paddocks compared with pens, and more females were  mated in pens. Duration of copulation was longer in pens that in  paddocks, and for first compared with subsequent matings. Within pens,  sexual activity was more intense during the first hour following joining  than for the subsequent 2.5 hours, on Day 1 than on Day 2, and differed  between groups. Females became more receptive later in the mating  sessions. The study indicated that pen mating using small single-sire  groups, over short periods, was a suitable method of breeding alpacas.  },

	abstract = {Aspects of seasonal physiology were monitored in red deer either untreated or treated with melatonin designed to advance the onset of the natural breeding season. Treated animals were implanted with melatonin at monthly intervals during December, January and February (adult stags and yearling hinds) or January and February (lactating hinds). Rutting behaviour, antler casting and velvet antler regrowth occurred up to 2 months earlier in melatonin-treated stags, while mean calving dates were advanced by 11 d in both groups of treated hinds. In yearling hinds, melatonin treatment advanced by about 1 month the phase of low growth which occurred in control hinds in autumn. However, treatment had little overall effect on live weight of yearling hinds or lactating hinds. Treated hinds moulted their red summer coats and grew lighter winter-like coats about 1 month earlier than untreated hinds. The growth rates of calves sucking melatonin-treated and untreated hinds were virtually identical. These results indicate that melatonin treatment can advance several aspects of seasonal physiology in deer.},

	abstract = {Six young red deer stags were placed on a photoperiod of 5 alternating periods of 2 months of 16 hours light: 8 hours dark each day (16 L:8 D) followed by 2 months of 8 L:16 D for 20 months. Food intake, whether the antlers were present, and if present, whether growing, cleaning or hard and testis diameter were recorded. Each stag showed 5 peaks and 5 troughs of food intake in response to the manipulated photoperiod. There were 4 cycles of gonadal development and regression as the testes did not descend from the inguinal canal during Period 1; testes grew in short day periods and diminished in size in long day periods. There were 4 cycles of antler growth and casting; antler cleaning occurred on short days and casting on long days. Male red deer are capable of responding to a square wave daylength pattern as a sinusoidal pattern.},
