  1. Effects of group housing systems on behaviour and production performance in farmed juvenile mink (Mustela vison)

    Contributor(s):: Pedersen, V., Jeppesen, L. L., Jeppesen, N.

    Juvenile mink were kept in two different group housing systems and their behaviour and physiology compared to that of juvenile mink kept traditionally in pairs. One group housing system was made by adjoining three traditional cages (row system) and the other by stacking a slightly smaller cage on...

  2. Implications of breaking mother-young social bonds. (Special Issue: Early Weaning.)

    | Contributor(s):: Newberry, R. C., Swanson, J. C.

    Whereas mammalian mothers and young may retain long-term social affiliations in nature, the management of animals in captivity typically dictates that offspring are abruptly and permanently separated from their mothers at a relatively early age, often prior to the time of natural weaning. For...

  3. Parturient behaviour and calf survival in a herd selected for twinning

    | Contributor(s):: Owens, J. L., Edey, T. N., Bindon, B. M., Piper, L. R.

    Over a three-year period dam and calf behaviour was observed in 47 single and 2 twin births from the time of behavioural signs of approaching parturition until first sucking in a herd of mixed Bos taurus beef and dairy breeds on improved pasture at Longford research station. Calf mortality was...

  4. Parturient behaviour in farmed mink ( Mustela vison ) in relation to early kit mortality

    | Contributor(s):: Malmkvist, J., Gade, M., Damm, B. I.

    Litter size and kit mortality are both relatively high in the production of farm mink, with the vast majority of deaths occurring around parturition and during the first days of life. Maternal care is crucial to ensure the survival of the vulnerable kits. This subject has received little...

  5. Periparturient behaviour in farmed blue foxes ( Alopex lagopus )

    | Contributor(s):: Pyykonen, T., Mononen, J., Ahola, L., Rekila, T.

    Recently, there has been criticism of the housing conditions available for farmed foxes. It is claimed that the present farm conditions are not appropriate for foxes and they lead to poor reproduction and abnormal behaviour such as maternal infanticide. Earlier studies have indicated that farmed...

  6. Handling and rearing results in young rabbits

    | Contributor(s):: Jezierski, T. A., Konecka, A. M.

    The effect of handling of rabbit pups and juveniles on their mortality rate and weight gain were investigated using 32 litters of New Zealand White rabbits. One or two pups were chosen at random from each litter and handled for 10 minutes a day starting when they were 10 days old. Rabbits...

  7. Maternal responsiveness of outdoor sows from first to fourth parities

    | Contributor(s):: Held, S., Mason, G., Mendl, M.

    Sows of indoor breeds are well known to differ in the speed and strength with which they respond to a piglet trapped under their bodies. There is also evidence from two previous studies that a sow's responsiveness to playback of a simulated trapped piglet scream is related to the number of...

  8. Maternal responsiveness of sows towards piglet's screams during the first 24 h postpartum

    | Contributor(s):: Illmann, G., Neuhauserova, K., Pokorna, Z., Chaloupkova, H., Simeckova, M.

    In this study we focused on sow responsiveness towards piglet screams which are proposed to have an important link to posture changes and early piglet crushing. A sow's responsiveness to screams of her piglets was investigated along the first 24 h after birth, the period of highest mortality, in...

  9. Preweaning mortality in loose-housed lactating sows: behavioral and performance differences between sows who crush or do not crush piglets

    | Contributor(s):: Johnson, A. K., Morrow, J. L., Dailey, J. W., McGlone, J. J.

    The majority of piglet deaths occur within the first 72 h after parturition, with crushing by the sow as the most common cause of preweaning mortality. The aim of this study was to compare the behavior and performance of sows that killed piglets (CR) to those that did not (NC) inside a farrowing...

  10. Animal welfare perspectives on recreational angling. (Special issue: Fish Behaviour and Welfare.)

    | Contributor(s):: Cooke, S. J., Sneddon, L. U.

    Fish captured by recreational anglers are often released either voluntarily or because of harvest regulations in a process called "catch-and-release". Catch-and-release angling is thought to be beneficial for the conservation of fish stocks based on the premise that most of the fish that are...

  11. Beak trimming and genetic stock effects on behaviour and mortality from cannibalism in white leghorn-type pullets

    | Contributor(s):: Craig, J. V., Lee, H. Y.

    Removal of half of the upper and less of the lower beak of pullet chicks at 4 weeks of age resulted in less pecking at feed, fewer non-agonistic pecks of all kinds, less moving and preening, and more inactive standing and crouching during the following 3 weeks. Escape and avoidance behaviour did...

  12. 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....

  13. Behaviour in suckling mink kits under farm conditions: effects of accessibility of drinking water

    | Contributor(s):: Brink, A. L., Jeppesen, L. L., Heller, K. E.

    Mortality in mink kits held under conventional farm conditions is believed to be related to dehydration and at least partially to thereby associated competitive aggression. In this study we demonstrated that licking saliva from the commissure of the dam's lips might serve to complement the kits'...

  14. Crushing of piglets by the mother sow ( Sus scrofa ) - purely accidental or a poor mother?

    | Contributor(s):: Andersen, I. L., Berg, S., Boe, K. E.

    Around 50% of the postnatal death in piglets is caused by crushing or overlying by the domestic sow (Sus scrofa) when they are kept loose in a farrowing pen. To solve some of these problems, much research attention has been directed towards the farrowing environment. However, previous experiments...

  15. Differential vulnerability of lambs to coyote predation

    | Contributor(s):: Blakesley, C. S., McGrew, J. C.

  16. Effects of accommodation type and straw bedding around parturition and during lactation on the behaviour of primiparous sows and survival and growth of piglets to weaning

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

    The effects of accommodation type (crate or pen) and bedding (with or without straw) were studied in 64 primiparous sows in 16 replicates. Sows that farrowed without straw had more liveborn piglets than sows with straw (9.4 vs. 9.1; P

  17. Effects of temporary nest box removal on maternal behaviour and pup survival in caged rabbits ( Oryctolagus cuniculus )

    | Contributor(s):: Baumann, P., Oester, H., Stauffacher, M.

    Free nest access is widely used in the management of commercial breeding units for fattening rabbits, but potentially counteracts the doe's behavioural goal of a closed nest entrance, leading to repeated nest visits without nursing and attempts to close the entrance due to an overtaxed...

  18. Long-stemmed straw as an additional nesting material in modified Schmid pens in a commercial breeding unit: effects on sow behaviour, and on piglet mortality and growth

    | Contributor(s):: Damm, B. I., Pedersen, L. J., Heiskanen, T., Nielsen, N. P.

    The aim of this study was to determine whether provision of nest materials in a form and amount that could be handled in a commercial Danish pig farm with modified Schmid pens would affect the environment for sows and piglets to an extent that could be detected in sow behaviour and parameters...

  19. Natural behavioural biology as a risk factor in carnivore welfare: how analysing species differences could help zoos improve enclosures. (Special Issue: Conservation, enrichment and animal behavior.)

    | Contributor(s):: Clubb, R., Mason, G. J.

    In captivity, some species often seem to thrive, while others are often prone to breeding problems, poor health, and repetitive stereotypic behaviour. Within carnivores, for instance, the brown bear, American mink and snow leopard typically adapt well to captivity and show few signs of poor...

  20. Rabbit nest construction and its relationship with litter development

    | Contributor(s):: Canali, E., Ferrante, V., Todeschini, R., Verga, M., Carenzi, C.

    The influence of maternal behaviour before parturition and of the microclimate on the development of young rabbits was evaluated for 3 successive litters of 32 New Zealand White rabbits. The quality of the straw nest improved from the 1st to the 3rd parturition, whereas the hair nest seemed to be...
