  1. Rearing conditions and needs for space and litter in laying hens

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

    Five groups of 4 hens reared in battery cages, and 5 groups of 4 hens reared in floor pens, were tested in an operant conditioning apparatus which allowed the hens to enlarge their cage by key pecking. Cage size could be varied between 1600 and 6100 cmsuperscript 2. The variable size section of...

  2. Research on alternatives to the battery system for laying hens

    Contributor(s):: Folsch, D. W., Huber, H. U., Bolter, U., Gozzoli, L.

    Alternatives to battery husbandry are described with reference to free-range husbandry, large indoor systems and other alternative systems which have been tested or introduced in various European countries. Factors required for animal welfare in such systems are described, and economics discussed.

    Contributor(s):: Broom, D. M.

  4. Stereotyped behaviour, social interactions and suckling pattern of pigs housed in groups or in single crates

    Contributor(s):: Arellano, P. E., Pijoan, C., Jacobson, L. D., Algers, B.

    The frequency of stereotypies, the nature of social interactions and whether sows or piglets initiate and terminate successful sucklings were compared. Sows on a commercial farm were housed in either crates or pens and studied for a year. Sows in crates developed significantly more stereotypies...

  5. Suckling behaviour of sows in farrowing crates and straw-bedded pens

    Contributor(s):: Cronin, G. M., Smith, J. A.

    The behaviour of 18 primiparous Large White (LW) or LW X Duroc sows and their litters was observed during 6 days in lactation (1, 2, 3, 7, 14 and 21) in 2 housing treatments: (1) farrowing crate (1.6 m x 2.2 m) without straw; (2) farrowing pen (2.8 m x 2.8 m) with straw added. After farrowing,...

  6. The development of agonistic behaviour in relation to the size of the farrowing pen

    Contributor(s):: Duijghuisen, J. A. H.

    The development of agonistic behaviour of piglets in two types of farrowing pen and their later behaviour as sows in groups was investigated. One type of farrowing pen was 3.85 msuperscript 2, the other was 6.85 msuperscript 2. In both types, agonistic interactions were analysed at an age of 2, 3...

  7. The effects of design of individual stalls on the social behaviour and physiological responses related to the welfare of pregnant pigs

    Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G.

    Plasma free-corticosteroid concentrations, aggressive behaviour and levels of motivation to interact socially and explore a novel environment were observed to test the hypothesis that the chronic stress response previously observed in tether-housed pigs may have been due to unresolved aggression...

  8. The effects of modifying the farrowing environment on sow behaviour and survival and growth of piglets

    Contributor(s):: Cronin, G. M., Amerongen, G. van

    Sixteen sows farrowed in standard crates (CC) or in the same crates modified (MC) by addition of straw on the floor and a hessian cover over the farrowing stall. About 6 h after farrowing was completed, the environments were made similar by removing the hessian cover in the MC treatment and...

  9. The effects of pregnancy and parity number on behavioural and physiological responses related to the welfare status of individual and group-housed pigs

    Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G., Fahy, V. A.

    Plasma free-corticosteroid concentrations, aggressive behaviour and motivation to interact socially and explore a novel environment were observed in 39 female pigs housed either in groups of 4-7 animals or in tether stalls over 2 parities. Gilts in tethers in their first pregnancy had...

  10. The effects of the gestation and farrowing environments on sow and piglet behaviour and piglet survival and growth in early lactation

    Contributor(s):: Cronin, G. M., Simpson, G. J., Hemsworth, P. H.

    96 Large White x Landrace pigs were housed in individual stalls or group pens during pregnancy and in conventional crates or a prototype pair-pen system during farrowing and lactation. The pair-pen system provided each sow with an area of approximately 10 msuperscript 2 and included a specific...

  11. The influence of pen size on toy preference of growing pigs

    Contributor(s):: Apple, J. K., Craig, J. V.

    Gilts 4 weeks of age were allotted to a large or a small pen (space allowance 0.8 and 0.4 msuperscript 2 per pig respectively), and offered a choice of 4 types of toys (knotted-end rope, length of rubber hose, piece of brass-plated chain, hourglass-shaped rubber dog). The toys were hung from the...

  12. The preparturient behaviour of sows in enriched pens and the effect of pre-formed nests

    Contributor(s):: Arey, D. S., Petchey, A. M., Fowler, V. R.

    The nest building behaviour of 12 preparturient sows was studied in enriched pens. Four categories of behaviour were observed: rooting, straw carrying, pawing and lying. In the 24 h before farrowing, 6 sows excavated hollows in sand floors and removed straw from dispensers to construct nests...

  13. Thermoregulatory behaviour of sheep housed in insulated and uninsulated buildings

    Contributor(s):: Boe, K.

    This study was made to investigate the thermoregulatory behaviour of sheep in confinement. In Experiment 1, two groups of 8 lambs in both an insulated (IN) and uninsulated (UN) house (total 32 animals) were studied; the durations of lying with and without body contact and standing were recorded...

  14. Companion animal renters and pet-friendly housing in the US

    Contributor(s):: Carlisle-Frank, P., Frank, J. M., Nielsen, L.

    A nationwide empirical study was conducted to determine the factors influencing the availability of pet-friendly rental housing throughout the US. Factors examined included an assessment of a variety of financial and economic factors, rental rates, deposits, turnover and damage histories, rental...

  15. Effects of group and individual housing on the behavior of kennelled dogs in animal shelters

    Contributor(s):: Mertens, P. A., Unshelm, J.

    To emphasize the effects of group- and single housing of kennelled dogs, the behavior of 211 dogs in two German animal shelters was tested and observed. After being placed, 197 of the dogs' new owners were interviewed.Although 51% of the German animal shelters already keep dogs in groups, there...

  16. Effects of winter housing, exercise, and dietary treatments on the behaviour and welfare of red deer ( Cervus elaphus ) hinds

    Contributor(s):: Pollard, J. C., Littlejohn, R. P.

    Behaviour, productivity, skin damage and adrenal response to ACTH challenge were measured in 6 groups of 8 weaner hinds over 91 days from June to September 1990 (winter) in Otago, New Zealand. The hinds were confined either indoors (I), indoors with daily exercise (IE) or outdoors (2 groups per...

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

    The preferences of growing pigs for substrates were investigated by giving groups of 6 pigs a choice between 2 substrates in each test. The 7 substrates examined were concrete, mushroom compost (spent), peat, sand, sawdust, straw and woodbark. 13 comparisons of pairs of substrates were tested...

  19. Rearing pigs in species-specific family groups

    Contributor(s):: Wechsler, B.

    In the Family Pen System, piglets and fatteners are reared in specific family groups that correspond to the normal social organization of domestic pigs. The feasibility of a technologically improved version of this alternative housing system, originally designed by Alex Stolba, was tested on a...
