  1. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  2. 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...

  3. Human-animal interaction, stress, and embryo production in Bos indicus embryo donors under tropical conditions

    Contributor(s):: Macedo, G. G., Zuccari Neto, C. E. S., Abreu, U. G. P. de, Negrao, J. A., Costa e Silva, E. V. da

    This study investigated the effect of human-animal interaction (HAI) and the stress response on the quality of embryo production in superovulated Nelore (Bos indicus) cattle, under tropical conditions. Thirty-two females underwent a superovulation protocol for 5 days. Cortisol concentrations were...

  4. Effect of different rearing systems and pre-kindling handling on behaviour and performance of rabbit does

    Contributor(s):: Mugnai, C., Bosco, A. dal, Castellini, C.

    The aim of this study was to ascertain how collective cage and pre-kindling handling (training does to go into their own nest) practices, in comparison to standard housing (single cage rearing), modify the behaviour and the performance of rabbit does. To this aim, 40 nulliparous New Zealand White...

  5. Nest provision influences reproductive success in breeding blue fox vixens: a preliminary study

    Contributor(s):: Pyykonen, T., Ahola, L., Hanninen, S., Mononen, J.

    The aim of the present study was to evaluate the effects of an unfamiliar nest and environmental enrichment, ie provision of an additional nest, on farmed blue fox (Alopex lagopus) vixens' reproductive performance. Two experimental groups were evaluated in the study: (i) a single nest (SN) group...
