During a 5-year study of lambing behaviour involving almost 1900 births by grazing ewes, the incidence of lambing peaked during the 5-h period 0900-1400 hours, when 28% of ewes lambed. Significant numbers of births occurred throughout the day, and so

Behavioural factors associated with lamb mortality were examined in regard to the relative effects of age and parity in single-bearing Merino ewes. Primiparas tended to have longer labour and higher lamb mortality than multiparous ewes. Maternal beha

Resistance to body cooling and rate of recovery from induced hypothermia were measured in 287 single, newborn Merino lambs from 24 different sire families, using a water bath test in which partly immersed lambs were progressively cooled. Birth weight

Ewe and lamb behaviour in traditional Border Leicesters, Glen Vale Border Leicesters of the NSW Agriculture and Fisheries, Glen Vale x Border Leicester crosses and medium-fine-wool Merinos, all running in paddocks of 3-4.5 ha, were compared in spring

This paper reports on birth-site distribution of Merinos and some British breeds in 34 lambing paddocks in a major study over 5 lambing seasons at Armidale New South Wales, and in minor studies during single lambing seasons, 2 in New South Wales and

This study documents an outbreak of congenital goitre in a flock of sheep under intensive observation for behaviour during lambing on pasture containing a high proportion of white clover (Trifolium repens). Thyroids were palpably enlarged in half of

The effects on maternal behaviour, of washing lambs and of confining ewes with alien lambs for several days, were examined in groups of Merino ewes that had lambed approximately 1, 3, 9 or 27 days previously. In the 1-, 3- and 9-day groups, 25–43%

Fostering an additional lamb on to a ewe with a single lamb of her own was attempted in Dorset, Corriedale and Merino ewes restrained by the neck in pens for up to 12 days. Fostering occurred more rapidly in Dorsets than in Merinos, and success rates

Behaviour of ewes at lambing was observed in a flock of N.Z. Romney sheep composed of selected (or “elite”) ewes that had produced litters of 2 or more lambs at least twice previously, and 2-year-old ewes that had produced 0, 1 or 2 lambs at 12 m

Transfer of odour between lambs less than 1 week old was attempted by the use of rectangular coats of hessian (a jute textile) worn for 24 h by a ewe's own lamb and then transferred to a potential foster lamb. In the absence of their own lamb, 50–6
