“…The current trial showed breeding suckling ewes did not enhance or adversely affect ovarian CL counts, oestrus activity, pregnancy rates or litter size in ewes bred 68-73 days postpartum. Breeding at this time would have ensured uterine involution was complete and, because the lambs suck less often and for shorter periods at that stage of lactation (Obregon et al 1992), less prolactin is released (Kann & Martinet 1975) which would thereby have less or no effect on ovarian activity.…”

The objective of this experiment was to determine the effect of lactation over the breeding period and early gestation on ewe reproductive performance and liveweight. Romney ewes (n = 206) with lambs at foot were allocated to either Early or Late weaning groups, synchronised with CIDRs and joined with Suffolk rams 69 days postpartum (P0). Lambs from the Early group were weaned at P0 while lambs from the Late group were weaned at P21. The ovaries of each ewe were observed laparascopically at P9. Late weaned lambs were significantly heavier (P < 0.001) at P21 and P47 than lambs in the Early group. There was no effect of ewe treatment on ewe reproductive performance, liveweight over the breeding period, number of corpora lutea present, pregnancy rates, or on liveweight of the ewes at the subsequent lambing and lactation. Birth and liveweights of subsequent lambs were not affected by the treatment of the ewe over the breeding period. This research suggests that the breeding of suckling ewes in an accelerated lamb production system has no effect on ewe reproductive performance or on subsequent lamb production.

“…The majority of these studies dealt with the in¯uence of geographical, environmental, anatomical or physiological parameters on the time of year of the lambing season. Most investigations of the behaviour of wild sheep at parturition have been carried out on animals in enclosures (Tschanz, 1962;Altmann, 1970;Shackleton & Haywood, 1985;Briedermann, 1989;Obrego Â n, de Reyna & Recuerda, 1992). However, these investigations have often not adequately re¯ected what happens in free-ranging animals.…”

We studied the behaviour of free-ranging female mou¯on sheep (age 3±5 years) in the period periparturition. The study area is situated in the north-east of Germany (52859'N, 13850'E). For continuous data collection, we used the storage-telemetry-system iry. Activity and foraging behaviour of ®ve females were recorded every second by electronic sensors integrated in a collar round the sheep Â s neck (weight 300 g). Whenever the animals visit a special`link-station', installed at a combined saltlick/feeder station, the recorded data are transmitted from the collar to the station and then to a laptop. In addition, we recorded continuously the presence of sheep at the saltlick using a camera-system, including a daylight and an infra-red camera.Activity of female mou¯on ranged from 8 to 10 hours daily during late winter. The animals spent the major part of that time feeding (70±80%). The sheep visited the saltlick every two to three days regularly. However, from late March to early April, every animal stayed away from the`link-station' for about two weeks. This meant spatial isolation from social companions. When returning, these sheep were accompanied by a lamb. Parturition was assumed to take place during 2±3 consecutive days of markedly decreased activity. In the night from the ®rst to the second day of this period, we found a unique activity pattern observed in all sheep. A short activity bout during the second half of the night was interpreted as the exact time of lambing. Spatial and temporal changes in behaviour during parturition are discussed with regard to other wild ungulates as well as domestic animals.
