Positive and negative gestational handling influences placental traits and mother-offspring behavior in dairy goats
Contributor(s):: Baxter, E. M., Mulligan, J., Hall, S. A., Donbavand, J. E., Palme, R., Aldujaili, E., Zanella, A. J., Dwyer, C. M.
Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect...
Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality
Contributor(s):: Muns, R., Manteca, X., Gasa, J.
An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

Effects of feed-back from the nest on maternal responsiveness and postural changes in primiparous sows during the first 24 h after farrowing onset
Contributor(s):: Pedersen, L. J., Damm, B. I., Marchant-Forde, J. N., Jensen, K. H.
In order to elucidate whether feed-back from a farrowing nest affects the sows' activity level and responsiveness to piglets during the first 24 h after the onset of parturition, 18 primiparous Landrace x Yorkshire sows were given the opportunity to build a farrowing nest of peat, straw and...
Sow behaviour during parturition in relation to the observed and the genetic merit for weaning survival
Contributor(s):: Uitdehaag, K. A., Ekkel, D., Kanis, E., Knol, E.
The sow's breeding value for mothering ability (EBVma) can be estimated as the genetic effect of the foster sow on piglet survival at weaning. Sows with a high EBVma have litters with a short average interval from birth until first colostrum intake. In the present study, it was investigated...

Allosuckling in cattle: gain or compensation?
Contributor(s):: Vichova, J., Bartos, L.
The objective of this study was to assess the impact of allosuckling on the growth of calves in a herd of domestic cattle. We determined (i) if allosucking calves achieved a better weight gain than non-allosucking calves ingesting milk surplus to maternal milk supply or if they were compensating...
Early piglet mortality in loose-housed sows related to sow and piglet behaviour and to the progress of parturition
Contributor(s):: Pedersen, L. J., Jorgensen, E., Heiskanen, T., Damm, B. I.
The aim of the present study was to identify characteristics of sow behaviour and parturition related to early piglet mortality in loose-housed farrowing sows. Data from 152 farrowings that originated from three different herds with loose-housed sows during parturition were used. Graphical chain...
Neonatal survival: contributions from behavioural studies in sheep
Contributor(s):: Nowak, R.
Newborn lambs need milk and immunological protection shortly after birth, and early interactions between the mother and the young are critical for this. Merino ewes in extensive conditions in Australia have the reputation of being a poor mothers. Attempts to improve the reproductive performance...
Welfare implications of artificial rearing and early weaning in sheep. (Special Issue: Early Weaning.)
Contributor(s):: Napolitano, F., Rosa, G. de, Sevi, A.
Soon after parturition a lasting and mutual ewe-lamb bond is established. However, in an increasing number of intensive sheep farms, lambs are separated from the dam at an early age. When artificial rearing is applied lambs are often kept with mothers for 2 days to allow the ingestion of maternal...
Effect of colostrum feeding method and presence of dam on the sleep, rest and sucking behaviour of newborn calves
| Contributor(s):: Hanninen, L., Hepola, H., Raussi, S., Saloniemi, H.
In rats, sucking milk reduces anxiety and promotes non-rapid eye movement (NREM) sleep, and in calves it induces resting but the effect on sleep is unknown. Here, we investigated how calves' sleep was affected by colostrum feeding methods. Forty-one calves were blocked by birth date and...
The provision of supplementary colostrum to newborn lambs: effects on post-natal lamb and ewe behaviour
| Contributor(s):: Gonzalez, S. G., Goddard, P. J.
The effect of supplementary colostrum on early mother-young behaviour was investigated in 18 pregnant twin-bearing Scottish Blackface hill ewes. At parturition, 1 lamb from each twin pair received 25 ml/kg birth weight artificial colostrum (treatment group) while the other was untreated (control...
A colostrum feeder for newborn lambs
| Contributor(s):: Fraser, D., Rushen, J.
Newborn lambs were studied in 6 experiments to identify simple cues that elicit teat-seeking behaviour, and to incorporate these cues into a device that would guide lambs to find and suck from a colostrum bottle. Lambs were removed from the ewe before sucking and were observed for 10 min in a...
