Effects of a post-partum separation on maternal responsiveness in primiparous and multiparous domestic goats
Contributor(s):: Lickliter, R. E.
Results contrasted with previous findings and indicated that goat mothers may display maternal caretaking behaviour towards their kids despite an immediate two hour post-partum separation of mother and young. The duration of unsolicited maternal responsiveness varied between individuals; in...

Factors which influence parturition in the mare and development of the foal
Contributor(s):: Campitelli, S., Carenzi, C., Verga, M.
127 foals born to 127 mares were studied. Mares aged 5, 6-11 and 12 yr gave birth to foals with birth weights of 42.65+or-6.175, 51.07+or-7.031 and 46.05+or-8.816 kg resp. and foetal membrane weights of 5.45+or-1.000, 6.27+or-1.191 and 6.37+or-1.104 kg; differences between age groups were...
Failure to mask lamb odour with odoriferous substances
Contributor(s):: Alexander, G., Stevens, D.
Lambs were still identified by their dams after their rumps had been smeared with various odoriferous substances. There appears to be no sound basis for the practice of farmers to mask lamb odour to facilitate fostering.
Incomplete nursing in the sow
Contributor(s):: Whatson, T. S.
This paper was presented at the Winter Meeting of the Society for Veterinary Ethology, held in London, UK on 10 Dec. 1977. An incomplete nursing was distinguished from a complete nursing by the absence of milk ejection. 9 sows with litters were observed in large rooms giving unrestricted movement...

Lamb mortality due to inadequate care of twins by Merino ewes
Contributor(s):: Stevens, D., Alexander, G., Lynch, J. J.
One hundred and three fine-woolled Merino ewes and their twin lambs in four 12-hectare paddocks, carrying 12.5 sheep per ha, were observed during daylight for 2-4 days immediately following parturition. Fifty-one ewes became permanently separated from one twin due to the ewe moving and leaving...
Mother-infant relationships in red deer
Contributor(s):: Hall, M. J.
Results are described of a study carried out on the Isle of Rhum with a group of fairly tame deer, kept in a 30-acre enclosure. It was found that mothers end a greater proportion of nursing bouts if they have a male calf than if they have a female, and also reject male calves' sucking attempts...
Observations on the nursing behaviour of beef cows suckling Charolais cross calves
Contributor(s):: Somerville, S. H., Lowman, B. G.
Three separate 48 h observations were made of the suckling behaviour of (1) Hereford X Friesian cows under grazing conditions, (2) Blue Grey cows under grazing conditions, and (3) Blue Grey cows housed. All the cows suckled Charolais cross calves. The mean suckling frequencies recorded were 5.5,...
Odour cues to maternal recognition of lambs: an investigation of some possible sources
Samples that might carry lamb-specific odour were tested in a three-choice system in which the ewe's interest in samples from herself or her own lamb, or samples from two other ewes or their lambs, were assessed. Each sample was suspended near the tail of an anaesthetized lamb from a ewe that was...

Recognition of washed lambs by Merino ewes
Responses of tranquilized post-partum ewes to alien lambs
Contributor(s):: Tomlinson, K. A., Price, E. O., Torell, D. T.
Eleven ewes whose young had been taken away 48-72 h after parturition, and nine ewes with a lamb of their own, were penned with alien lambs following a single injection of the tranquillizer perphenazine. Seventeen control ewes, including 15 whose only young had been taken away, were also exposed...
Role of auditory and visual cues in mutual recognition between ewes and lambs in Merino sheep
Separation of ewes from twin lambs: incidence in several sheep breeds
Contributor(s):: Alexander, G., Stevens, D., Kilgour, R., Langen, H. de, Mottershead, B. E., Lynch, J. J.
The ability of ewes and their lambs to keep together during the 1st and 2nd day of life, when the mother-offspring bond is consolidating, was examined in fine-wool Merino, Dorset Horn, Romney and Suffolk X (Border Leicester X Merino) sheep. 45.7% of twin-bearing Merinos became permanently...
Some factors involved in natural weaning processes in sheep
Contributor(s):: Arnold, G. W., Wallace, S. R., Maller, R. A.
Milk production of ewes was measured during four-hour periods each week at varying stages of lactation. Lambs were separated from the ewes during this period before being reunited and the behavioural responses of each to the other were recorded. The responses were classed according to an...
Some observations on mother-infant interactions in the pig (Sus scrofa)
Contributor(s):: Whatson, T. S., Bertram, J. M.
The overt behaviour of sows towards their piglets and piglets towards their dams not related to sucking or suckling was examined in 18 litters over the course of a 5-week lactation. Sows were housed either in typical, restrictive, commercial conditions or in a slightly larger area without the...
