Feeding and sleep patterns prior to and post parturition
Contributor(s):: Ruckebusch, Y.
Continuous recordings of jaw movements and sleep patterns (eye movement), were made on 2 cows aged 4 yr, before calving and during early lactation. Calves were separated from their dams immediately after birth and the cows were milked 2 X daily at 9 am and 5 pm during which time they received...
Sleep as an index of an animal's adaptation to its environment
Sleep in piglets: an observational study
Contributor(s):: Kuipers, M., Whatson, T. S.
The development of sleep was examined in 16 piglets during their first 5 weeks of life. Each piglet was observed for one 90-minute period each week and a record of the duration of lying, non-REM (rapid eye movement) sleep and REM sleep was made. Sleeping position was also recorded. The amount of...

A note on a behavioural indicator of satisfaction in stabled horses
| Contributor(s):: Ninomiya, S., Sato, S., Kusunose, R., Mitumasu, T., Obara, Y.
We observed the behaviour of six stabled horses (stallions n=3; geldings n=3) in an attempt to identify behavioural measures of eating satisfaction. The horses were required to perform an operant response (pressing a button with the muzzle) in order to access a food reward in an experimental box...
The preference of individually-penned cattle to conduct certain behaviours in the light or the dark
| Contributor(s):: Phillips, C. J. C., Arab, T. M.
The behaviour of individually-penned cattle, able to switch lights on and off, was recorded over a 5 days. The cattle showed only a weak preference to feed in the light and to be in the light when they were standing or lying doing nothing. They showed no clear evidence of preferring to sleep or...
The reaction of cows to a short-term deprivation of lying
| Contributor(s):: Metz, J. H. M.
In a herd of 20 cows in a cubicle house, lying behaviour was prevented for 3 h each morning by enclosing the animals on the slatted floor of the feeding area. Lying time of cows was recorded during the 10 h following deprivation. The 3 h of lying deprivation resulted in a recovery rate of almost...
Assessing sleep state in calves through electrophysiological and behavioural recordings: a preliminary study
| Contributor(s):: Hanninen, L., Makela, J. P., Rushen, J., Passille, A. M. de, Saloniemi, H.
Adequate sleep is important for the health and well being of animals but we lack non-invasive methods to record sleep states from group-housed, freely-moving farm animals. We used electrophysiological data (electroencephalography; EEG, electromyography; EMG, and electro-oculography; EOG) to...
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...

Behavioural responses to barking and other auditory stimuli during night-time sleeping and waking in the domestic dog ( Canis familiaris )
| Contributor(s):: Adams, G. J., Johnson, K. G.
Urban dogs have previously been shown to have approximately 3 sleep/wake cycles per hour during the night. In this study the sensitivity of dogs to night-time stimuli at different stages of these sleep/wake cycles was tested. 12 dogs were filmed at night in their usual urban habitats, whilst...
Effects of intermittent lighting on sleep and activity in the domestic hen
| Contributor(s):: Coenen, A. M. L., Wolters, E. M. T. J., Luijtelaar, E. L. J. M. van, Blokhuis, H. J.
The effects were studied of two different light-dark regimes on general activity, behavioural patterns and sleep in domestic hens. The light-dark schemes were composed of a traditional 14 h light-10 h dark period and the Biomittent Lighting Program (BMLP), which consists of only 15 minutes light...
Guard dogs: sleep, work and the behavioural responses to people and other stimuli
Sleep-wake cycles and the responses to naturally occurring stimuli were studied in 17 guard dogs; detailed video recordings were made of 10 of these dogs. The guard dogs lived permanently on-site, or were commercially owned and brought on to premises, removed before the workers started and rested...
Let sleeping rats lie: does the timing of husbandry procedures affect laboratory rat behaviour, physiology and welfare?
| Contributor(s):: Abou-Ismail, U. A., Burman, O. H. P., Nicol, C. J., Mendl, M.
Research has indicated that chronic stress can reduce sleep quality and quantity. Yet there has been little investigation into whether husbandry procedures carried out during an animal's normal sleeping period affect subsequent sleep behaviour and welfare. We housed 48 rats in enriched cages...

Sleep, work, and the effects of shift work in drug detector dogs Canis familiaris
Sleep-wake cycles of 6 drug detector dogs were video recorded, and the effects on them of shift work assessed. Observations were also recorded of interactions between dogs and their handlers during rest and work. Non-working dogs recorded immediately after work or at the same time of day or night...
