  1. Feeder design and available feeding space influence the feeding behaviour of hens

    Contributor(s):: Huon, F., Menuier-Salaun, M. C., Faure, J. M.

    The effects of 8 feeder designs and available feeding space were examined in 15 groups of 3 laying hens in deep litter pens. Feeding rates and the number of feeding bouts were higher, feed consumption lower and duration of feeding shorter in partitioned than unpartitioned feeders. Feeding times...

  2. Incidence of oestrus and oestrous trends in lactating sows housed in different social and physical environments

    Contributor(s):: Henderson, R., Stolba, A.

    Lactating sows were kept in conventional farrowing crates, larger pens with outside yards, or family pens for sows and progeny up to 60 kg body weight. Additional treatments, allowing contact with other sows and/or boars and restricted piglet contact, were applied to some sows. Various...

  3. Influence of environmental stimuli on maternal behaviour related to bonding, reactivity and crushing of piglets in domestic sows

    Contributor(s):: Herskin, M. S., Jensen, K. H., Thodberg, K.

    Effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined in a 2 x 2 factorial experiment with 9 replicates of 4 multiparous sows. From one week prepartum until 13-15 days postpartum, sows were kept individually in 'get-away pens' with a 7.6...

  4. Inter-individual distances and orientation in laying hens housed in groups of three in two different-sized enclosures

    Contributor(s):: Keeling, L. J., Duncan, I. J. H.

    Groups of 3 hens were placed in pens of two different sizes (0.65x0.65 and 1.3x1.3 m) and the locations of individuals were determined using overhead time-lapse photography. The birds did not use the areas evenly. Hens in the small pen tended to use the corners, whereas the centre of the large...

  5. Inventory of the behaviour of New Zealand White rabbits in laboratory cages

    Contributor(s):: Gunn, D., Morton, D. B.

  6. Perch use, plumage and foot condition and bone strength in caged hens

    Contributor(s):: Hughes, B. O., Appleby, M. C.

  7. Preferences of domestic hens for cage size and floor types as measured by operant conditioning

    Contributor(s):: Lagadic, H., Faure, J. M.

    Five groups of 4 hens were trained to increase the size of their cage by means of key pecking in an operant conditioning apparatus. Cage sizes could be varied between 1600 and 6100 cmsuperscript 2. The cage floor could be either wood shavings or wire mesh. Hens spent approximately 50% of their...

  8. Preferences of pregnant sows for wet and dry concrete floors

    Contributor(s):: Hutson, G. D., Haskell, M. J., Dickenson, L. G., Slinger, D. E.

    Preference was assessed by providing sows with access to two adjacent pens, one with a dry concrete floor and the other with a wet concrete floor. Sows were fed in either the wet pen or dry pen and allowed continuous free access to both pens, or they were confined overnight in one of the pens and...

  9. Relationship between behavioural activity and social space requirements in laying hens

    Contributor(s):: Keeling, L.

  10. Relationship between immune response, liveweight gain, behaviour and adrenal function in red deer ( Cervus elaphus ) calves derived from wild and farmed stock, maintained at two housing densities

    Contributor(s):: Hanlon, A. J., Rhind, S. M., Reid, H. W., Burrells, C., Lawrence, A. B., Milne, J. A., McMillen, S. R.

    Immune response and other potential measures of stress were assessed in 40 weaned red deer calves in a 2 x 2 factorial experiment. Replicate groups of five calves (aged about 3 months) born to dams from two sources (wild, (W) or farmed, (F)) were housed at weaning at one of two stocking densities...

  11. Seasonal changes in platform use by farmed blue foxes ( Alopex lagopus )

    Contributor(s):: Korhonen, H., Niemela, P., Tuuri, H.

    Seasonal changes in platform use were investigated in farm-raised blue foxes (Alopex lagopus) by daytime scan sampling observations and 24-h video recordings. Seasonal comparisons were made in both sexes, but other experimental treatments were applied mainly to females. Platform use was minimal...

  12. Spacing behaviour and an ethological approach to assessing optimum space allocations for groups of laying hens

    Contributor(s):: Keeling, L.

  13. The adaptation of hill lambs to housing conditions

    Contributor(s):: Goddard, P. J., Fawcett, A. R., Macdonald, A. J.

    Sixty Scottish Blackface weaned castrated male lambs (mean age, 20 weeks), reared under extensive management conditions with minimal human contact, were used to study responses to housing and increased contact with humans. One group of 12 lambs was tested immediately at the commencement of the...

  14. The effect of housing system on the activity level and bone strength of laying hens

    Contributor(s):: Knowles, T. G.

  15. The effect of space allowance and sex on blood catecholamines and cortisol, feed consumption and average daily gain in growing lambs

    Contributor(s):: Horton, G. M. J., Malinowski, K., Burgher, C. C., Palatini, D. D.

    The effect of space allowance of 0.37, 0.62 and 0.99 msuperscript 2/lambs and sex on plasma norepinephrine, epinephrine and cortisol concentrations, feed consumption and average daily gain in Dorset lambs 11 weeks old about 21.7 kg (ewe) and 25.7 kg (ram) was examined. Lambs reared in a common...

  16. The influence of conditions at the time of mating on the sexual behaviour of male and female pigs

    Contributor(s):: Jongman, E. C., Hemsworth, P. H., Galloway, D. B.

    The sexual behaviour of 6-month-old boars and gilts mating in the boar's accommodation pen was compared with that of boars and gilts mating in a mating system called the Detection Mating Area (DMA), in which the boars are housed in individual stalls around a large central arena which is used for...

  17. The influence of mating conditions on the sexual behaviour of male and female pigs

    Contributor(s):: Hemsworth, P. H., Hansen, C., Winfield, C. G.

    Sixteen boars, aged 7 months, and 48 ovariectomised gilts, aged 7 months, were randomly allotted to mating in the boar's accommodation pen (boar pen treatment) or in an octagonal mating pen (mating pen treatment). One of 2 groups of gilts was induced into behavioural oestrus on alternate wk...

  18. An investigation of the effect of environmental enrichment and space allowance on the behaviour and production of growing pigs

    Contributor(s):: Beattie, V. E., Walker, N., Sneddon, I. A.

    Newly weaned 6-week-old pigs in groups of 6 littermates were placed in enriched environments with a floor space allowance of 0.5, 1.1, 1.7 or 2.3 msuperscript 2/pig (treatments 1-4, respectively). Treatment 5 was identical to treatment 4, except for the absence of enriching elements which...

  19. Behaviour and productivity of sows and piglets in a family system and in farrowing crates

    Contributor(s):: Arey, D. S., Sancha, E. S.

    48 sows and their litters were randomly allocated to housing in a family pen system (FS) or in farrowing crates (FC) during day-time for 4 weeks after farrowing. FS sows were housed in groups of 4 in enclosures with voluntary access to straw-bedded farrowing pens and an outer communal area....

  20. Behaviour of laying hens during induced moulting in three different production systems

    Contributor(s):: Aggrey, S. E., Kroetzl, H., Foelsch, D. W.

    This work is a critical investigation of how methods of moulting are practiced by farmers. Dekalb hens were fasted with a reduced photoperiod to induce moult and hence lengthen the total egg laying period in three housing systems, namely wire floor, multifloor (globovolg) and battery cages. The...
