Mid- and late-pregnancy ewe shearing affects lamb neonatal reactivity and vigour
Contributor(s):: Labeur, Léa, Small, Alison H., Hinch, Geoff N., McFarlane, James R., Schmoelzl, Sabine
Poor lamb survival is an important production and welfare issue, and the lamb must express complex behaviours to successfully transition to life ex-utero. Even under best management practices, sheep husbandry events, such as shearing, yarding and transport can be stressful for animals, and when...
Male-free environment prevents pregnancy disruption in domestic horse mares mated away of home
Contributor(s):: Bartoš, Luděk, Bartošová, Jitka, Pluháček, Jan
In a previous study (Bartos et al., 2011) we have reported on the effects of the male social environment on the maintenance or disruption of pregnancy in domestic mares mated away from home. In this follow-up study we compare the effects of returning to a home environment including a male (or...
Strategic use of straw increases nest building in loose housed farrowing sows
Contributor(s):: Westin, R., Hultgren, J., Algers, B.
In spite of domestication, sows are still genetically programmed to perform nesting behaviour close to farrowing. In order to facilitate nest building, a method for a strategic use of large quantities of straw has been developed by Swedish piglet producing farmers. The objectives of the present...

Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows
Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.
We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...
How should the welfare of fetal and neurologically immature postnatal animals be protected?
Contributor(s):: Campbell, M., Mellor, D. J., Sandoe, P.
Legal protection of the welfare of prenatal animals has not previously been addressed as a discrete subject within the academic literature on animal welfare, ethics and law. This paper aims to rectify this by reviewing the protections (or absence of protections) provided for fetuses by existing...
Relationships between pig welfare, productivity and farmer disposition
Contributor(s):: Jaaskelainen, T., Kauppinen, T., Vesala, K. M., Valros, A.
The aim of this study was, firstly, to investigate the connection between on-farm assessed welfare scores and production parameters for sows, and secondly, to examine how farmers perceive the connection between their disposition, animal welfare and productivity. We assessed environmental and...
Risk factors for unassisted on-farm death in Swedish dairy cows
Contributor(s):: Alvasen, K., Thomsen, P. T., Sandgren, C. H., Mork, M. J., Emanuelson, U.
Increased on-farm cow mortality (ie unassisted death and euthanasia) has been demonstrated in Swedish dairy herds during the last decade. Identifying risk factors associated with type of death is needed for future work in reducing cow mortality rates. The objectives of this case-control study...

A note on the relationship between the behavioural response of lactating sows to humans and the survival of their piglets
Contributor(s):: Hemsworth, P. H., Pedersen, V., Cox, M., Cronin, G. M., Coleman, G. J.
The objective of this study was to examine the relationships, based on unit averages, between the behavioural responses of lactating sows to humans and the performance of sows in 25 farrowing units at a large commercial farm. The behavioural responses of 25 sows in each farrowing unit were...
Farrowing behaviour and stillbirth in two environments: an evaluation of the restraint-stillbirth hypothesis
Contributor(s):: Fraser, D., Phillips, P. A., Thompson, B. K.
59 farrowings were studied in either a conventional, narrow farrowing crate (0.43 m wide) or a much wider alternative design with sides spaced 1.2 m apart at the sow's standing height but narrowing near the floor to limit the sow's lying area. Using video recording, each "birth interval" (i.e....
Formation and dissolution of the mare-foal bond
Contributor(s):: Houpt, K. A.
The behaviour of mares at foaling and their behaviour during subsequent weekly brief separations from their foals was quantified. 13 multiparous pony mares were observed for the first 30 min after foaling. Activities directed toward the foal and toward the fetal membranes were recorded. There...
Ultrasound observations of fetal movements in the pig: an exploratory study
Contributor(s):: Cohen, S., Mulder, E. J. H., Oord, H. A. van, Jonker, F. H., Weijden, G. C. van der, Taverne, M. A. M.
The feasibility and practical conditions of repeated, non-invasive ultrasound scanning for fetal movements during late gestation in the pig were studied. After a short training period of the sow, good quality recordings of fetal movements were obtained for 60 min using a 3.5 MHz ultrasound...
An exploratory ultrasonic study on quantitative foetal kinesis in the horse
Contributor(s):: Fraser, A. F., Hastie, H., Callicott, R. B., Brownlie, S.
Fetal movement was examined in 62 mares with an intra-pelvic transducer probe. Simple, singular movements were common and regular from the third month onwards, avaraging 55 per hour. Movements of greater complexity were detected in the more mature fetus, and increased from 6 per hour in the...
Fetal kinesis and a condition of fetal inertia in equine and bovine subjects
Contributor(s):: Fraser, A. F.
A salient feature of behaviour in the fetus is movement. Kinetic behaviour in equine and bovine fetuses has been progressively studied in recent years using doppler ultrasound. As specific features of fetal kinesis have become identified in this study, fetal behaviour patterns have become...

Radiographic studies of postural behaviour in the sheep fetus: I. Simple fetal movements. II. Complex fetal movements
Contributor(s):: Fraser, A. F., Terhune, M.
Behaviour during the 80-120-day phase of the gestation was studied in 124 sheep fetuses. Lack of "polarity" of fetal position was evident at this stage, although more transverse positions were evident in singles and twins than among triplets and quadruplets. The frequency of kinesis was similar...
