  1. Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  2. Mate choice, maternal investment and implications for ostrich welfare in a farming environment

    Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.

    At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

  3. Flight distance and reaction to fawn handling are greater in high- than in low-ranked pampas deer ( Ozotoceros bezoarticus) females

    Contributor(s):: Ungerfeld, R., Morales-Pineyrua, J. T., Freitas-de-Melo, A.

    The flight distance from humans and the reaction of the mother to human handling of their offspring are measures that can be used to assess the quality of the human-animal relationship which could vary according to animals' position in a group. The objective was to determine if the flight...

  4. Pregnant cattle associations and links to maternal reciprocity

    Contributor(s):: Swain, D. L., Patison, K. P., Heath, B. M., Bishop-Hurley, G. J., Finger, A.

    Cattle are a highly gregarious species that form strong social connections. Social support following calving serves to increase offspring survival and conception rates for the following breeding season. It has been shown that cattle change their association preferences following calving, but the...

  5. Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink

    Contributor(s):: Malmkvist, J., Palme, R.

    Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...

  6. Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator

    Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.

    Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...

  7. Evaluating the effect of semi-group housing of rabbit does on their offspring's fearfulness: can we use the open-field test?

    Contributor(s):: Buijs, S., Tuyttens, F. A. M.

    Breeding does are usually housed one doe per cage, but there is an increased interest in (semi-)group housing systems designed to improve welfare. However, there is a lack of information on how such systems actually affect different aspects of rabbit welfare. We aimed to discern differences in...

  8. Aggression and welfare in a common aquarium fish, the Midas cichlid

    Contributor(s):: Oldfield, R. G.

    Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively in order to defend resources such as food, shelter, mates, and offspring. The decision to defend...

  9. Dog breeding in New Providence, the Bahamas, and its potential impact on the roaming dog population I: planned and accidental

    Contributor(s):: Fielding, W. J.

    This article reports the first known study on dog breeding in an Afro-Caribbean community. The study obtained the information on 517 matings through interviews with dog caregivers. Few litters (6.8%) from mongrels (potcakes) resulted from planned matings, whereas 66.5% of matings between purebred...

  10. Improved acceptance of Chromonaela odorata by goat kids after weaning is caused by in utero exposure during late but not early pregnancy

    Contributor(s):: Phan Vu, Hai, Schonewille, J. T., Dam Van, Tien, Everts, H., Hendriks, W. H.

    The aim of the current experiment was to study the effect of the phase of pregnancy on in utero learning of Chromonaela odorata by the goat kids by comparing mid pregnancy (day 50-99, MP) with late pregnancy (day 100-145, LP). It was hypothesized that kids born to dams fed C. odorata during late...

  11. The role of genes, epigenetics and ontogeny in behavioural development

    Contributor(s):: Rodenburg, T. B.

    This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...

  12. Effect of housing and husbandry practices on adrenocortical activity in captive Canada lynx ( Lynx canadensis)

    Contributor(s):: Fanson, K. V., Wielebnowski, N. C.

    Contributor(s):: Stehulova, I., Spinka, M., Sarova, R., Machova, L., Knez, R., Firla, P.

  15. Nest-building in sows: effects of farrowing housing on hormonal modulation of maternal characteristics
