Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs
Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.
The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...
Clinical feasibility of cognitive testing in dogs ( Canis lupus familiaris)
Contributor(s):: Heckler, M. C. T., Tranquilim, M. V., Svicero, D. J., Barbosa, L., Amorim, R. M.
Several cognitive tests have been developed to evaluate specific aspects of human and animal learning and memory. These tests have been used for early detection of cognitive deficits and to monitor the treatment of dogs with cognitive impairment. Thus, this article evaluated the feasibility of...
Development of a methodology for studying feeding station behaviour of grazing ewes
Contributor(s):: Roguet, C., Prache, S., Petit, M.
A test apparatus was developed to study feeding station (FS) use and abandonment by sheep, by controlling FS number, characteristics and distance between FS. It consisted of a rectangular pen with openings in one of the long sides through which the sheep could extend its head to graze. FS...
Effect of dietary fibre and feeding system on activity and oral behaviour of group housed gilts
Contributor(s):: Brouns, F., Edwards, S. A., English, P. R.
The low feeding level common in practice for dry sows has been linked to the occurrence of stereotypies. A total of 54 gilts were allocated to three treatments and housed in groups of 6 in straw bedded pens with individual feeding stalls. The treatments consisted of control (C) 2.0 kg of a...
Effect of forage presentation on feed intake behaviour in stabled horses
Contributor(s):: Ellis, A. D., Fell, M., Luck, K., Gill, L., Owen, H., Briars, H., Barfoot, C., Harris, P.
In some stabled horses, the lack of foraging opportunity leads to a reduction in chewing time with consequent negative impacts on the digestive system and potentially development of stereotypies. This study aimed to compare the effect of four types of haynets on feed intake behaviour in stabled...
Habitus and responsible dog-ownership: reconsidering the health promotion implications of 'dog-shaped' holes in people's lives
Contributor(s):: Degeling, C., Rock, M., Rogers, W., Riley, T.
Responsible dog ownership has been identified as a point of intervention to promote physical activity, based upon an expectation of dog walking in public space. Nevertheless, quantitative research has found variability among owners in their dog walking. In this study, we explore the implications...
Hippotherapy and features of horses used in therapyHippoterapi ve terapide kullanilan atlarin ozellikleri
Contributor(s):: Koseman, A., Seker, I.
The aim of this study is to highlight both the hippotherapy, which is used as a method of therapy for mentally and physically disabled individuals and features of horses used in therapy. Shortly, hippotherapy, which means "the therapy by means of a horse", has neuro-physiological mechanism....
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...
Human-animal relationship: stockmanship and housing in organic livestock systems
Contributor(s):: M. Hovi (editor), M. Bouihol (editor)
The theme of the 3rd NAHWOA Workshop was "Human-animal relationship: stockmanship and housing in organic livestock systems". The stockperson's ability to understand livestock and to respond to the needs of the domesticated animals is probably the most important building block of animal health and...

Periods of early development and the effects of stimulation and social experiences in the canine
Contributor(s):: Battaglia, C. L.
It is not capacity that explains the differences that exist between individuals, because most seem to have far more capacity than they will ever use. The differences that exist between individuals seem to be related to something else. Researchers have studied these phenomena and have looked for...

Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age
Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.
Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...
The effects of metabolic cage housing and sex on cognitive bias expression in rats
Contributor(s):: Barker, T. H., Howarth, G. S., Whittaker, A. L.
The use of metabolic cages is established housing protocol in small-animal, gastrointestinal research. Physiological data, as primarily observed through secretions of the hypothalamic-pituitary-adrenal axis has shown that rodents housed in this manner experience an increased stress response. Few...
The effects of restriction of movement on the reliability of heart rate variability measurements in the horse ( Equus caballus)
Contributor(s):: Vitale, V., Balocchi, R., Varanini, M., Sgorbini, M., Macerata, A., Sighieri, C., Baragli, P.
Analysis of heart rate variability (HRV) is a noninvasive approach for investigating the sympathovagal balance of the autonomic nervous system. In recent years, HRV has been increasingly evaluated in animal research. In horses, it has been suggested that basal resting conditions can be achieved...
The influence of social hierarchy on the time budget of cows and their visits to an automatic milking system
Contributor(s):: Ketelaar-de Lauwere, C. C., Devir, S., Metz, J. H. M.
The effects of social dominance on dairy cows' (crossbred Holstein-Friesian; n = 30) visits to an automatic milking system (AMS) and their daily activity pattern was studied. Cows were fed on concentrate and milked in the AMS, which consisted of 2 selection units (sending cows for milking or back...

Variation in maternal behaviour and production of sows in integrated loose housing systems in Norway
Contributor(s):: Boe, K.
In studies of pig production data on 15 farms, the number of liveborn piglets per litter was somewhat lower and the losses from farrowing to weaning slightly higher in than the average of Norwegian herds. Maternal behaviour was studied on 9 of the farms. The time the sow spent with her piglets...

Why the question of animal consciousness might not matter very much
Contributor(s):: Peter Carruthers
According to higher-order thought accounts of phenomenal consciousness (e.g. Carruthers, 2000) it is unlikely that many non-human animals undergo phenomenally conscious experiences. Many people believe that this result would have deep and far-reaching consequences. More specifically, they believe...
