  1. Effect of late gestational feed restriction and glucogenic precursor on behaviour and performance of Ghezel ewes and their offspring

    Contributor(s):: Ahmadzadeh, Leila, Hosseinkhani, Ali, Taghizadeh, Akbar, Ghasemi-Panahi, Babak, Hamidian, Gholamreza

    Maternal undernutrition during pregnancy impairs offspring behaviours and thereby their survival rate indirectly by decreasing lamb birth weight or by deteriorating milk production which in turn limits bonding of the dam with the neonate. This study was aimed to investigate the effect of maternal...

  2. Pre-weaning socialization and environmental enrichment affect life-long response to regrouping in commercially-reared pigs

    Contributor(s):: Ko, Heng-Lun, Chong, Qiai, Escribano, Damián, Camerlink, Irene, Manteca, Xavier, Llonch, Pol

    Weaning and other regrouping events as routine work in commercial farms cause stress to pigs and compromise their welfare. Several studies found positive outcomes to mitigate weaning stress when piglets were socialized (i.e. co-mingled) or raised with enrichment materials in research settings....

  3. Suckling, weaning, and the development of oral behaviours in dairy calves

    Contributor(s):: Veissier, Isabelle, Caré, Sara, Pomiès, Dominique

    Dairy calves are generally separated from their dam at birth. They express non-nutritive oral activities such as licking or sucking other calves or objects, nibbling, or tongue-playing, which have been related to the absence of sucking a teat and ingestive chewing. We hypothesized that the dam,...

  4. Socialising piglets in lactation positively affects their post-weaning behaviour

    Contributor(s):: Morgan, Talia, Pluske, John, Miller, David, Collins, Teresa, Barnes, Anne L., Wemelsfelder, Françoise, Fleming, Patricia A.

    Although commercial farrowing sheds keep individual litters separated, previous studies have suggested that housing systems that allow socialisation of piglets pre-weaning can reduce aggression after weaning. This study tested whether pigs socialised with non-litter mates pre-weaning would show...

  5. Facilitating ‘learning from mom how to eat like a pig’ to improve welfare of piglets around weaning

    Contributor(s):: Oostindjer, Marije, Kemp, Bas, van den Brand, Henry, Bolhuis, J. Elizabeth

    Piglets in commercial husbandry are weaned abruptly and at a rather young age. Many weanling piglets are poorly adapted to ingest solid food, often resulting in a period of underfeeding. The underfeeding generally leads to a poor growth, diarrhoea occurrence and the development of damaging...

  6. Comparison of the effects of weaning and castration when conducted separately or in combination on the behaviour of crossbred beef cattle

    Contributor(s):: Lambertz, Christian, Farke-Röver, Antje, Moors, Eva, Gauly, Matthias

    The objective of the present study was to evaluate the behavioural effects of Burdizzo castration of crossbred beef calves when weaned and castrated separately (castrated 8 weeks after weaning) or in combination. Over two consecutive years a total of 111 Limousin×Simmental male calves were...

  7. Behavioural patterns established during suckling reappear when piglets are forced to form a new dominance hierarchy

    Contributor(s):: Skok, Janko, Prevolnik, Maja, Urek, Tina, Mesarec, Nikolina, Škorjanc, Dejan

    Early life experiences considerably influence the behavioural development of the animals in which the social environment plays a crucial role. Neonatal piglets experience intense social (including aggressive) interactions when compete with their littermates for the access to teats on the sow's...

  8. Laboratory macaques: When to wean?

    Contributor(s):: Prescott, Mark J., Nixon, Mellissa E., Farningham, David A. H., Naiken, Sandiren, Griffiths, Mary-Ann

    Worldwide there is large variation in the age at which young macaques destined for use in research are permanently separated from their mothers, and in the subsequent social environment in which they are reared. This stems from variation in minimum weaning ages and rearing practices in guidelines...

  9. Effects of environmental enrichment and loose housing of lactating sows on piglet behaviour before and after weaning

    Contributor(s):: Oostindjer, Marije, van den Brand, Henry, Kemp, Bas, Bolhuis, J. Elizabeth

    Weaning of piglets in commercial husbandry systems is earlier and more abrupt than would happen under natural conditions, resulting in low feed intakes and health and welfare problems in the immediate postweaning period. Piglets in commercial systems generally have limited opportunities to learn...

  10. Disentangling the effects of weaning stressors on piglets’ behaviour and feed intake: Changing the housing and social environment

    Contributor(s):: Hötzel, Maria J., de Souza, Gisele P. P., Costa, Osmar A. Dalla, Machado Filho, Luiz Carlos P.

    Under farming conditions piglets generally face several simultaneous stressors including separation from the dam, an abrupt change from milk to a solid diet and changes in the social and housing environments. In this study we tested the hypothesis that increasing the number of environmental...

  11. Cross-sucking by dairy calves may become a habit or reflect characteristics of individual calves more than milk allowance or weaning

    Contributor(s):: de Passillé, Anne Marie, Borderas, Fernando, Rushen, Jeffrey

    To examine the effects of milk allowance and weaning age on cross-sucking, 45 dairy calves were housed in groups of nine and fed milk and grain-based starter feed from automated feeders and allocated to three treatment groups: (A) Low-Milk Early-Weaned (fed 6L/d of milk until weaned at 47 d of...

  12. Coping personality type and environmental enrichment affect aggression at weaning in pigs

    Contributor(s):: Melotti, Luca, Oostindjer, Marije, Bolhuis, J. Elizabeth, Held, Suzanne, Mendl, Michael

    This study investigated the effects of different environmental treatments and personality types on aggression at mixing of newly weaned domestic piglets. From birth to weaning, 16 litters were housed with their dams in either barren (B) or larger, substrate-enriched (E) environments. At 15 days...

  13. Personality is associated with feeding behavior and performance in dairy calves

    Contributor(s):: Neave, H. W., Costa, J. H. C., Weary, D. M., von Keyserlingk, M. A. G.

  14. Is tail biting in growing pigs reduced by a prolonged suckling period?

    Contributor(s):: Naya, Ashley, Traulsen, Imke, Gertz, Marvin, Hasler, Mario, Burfeind, Onno, große Beilage, Elisabeth, Krieter, Joachim

    It was the aim of the study to investigate the effect of a prolonged suckling period and group housing before weaning on tail biting in undocked nursery pigs. To do this, experiments with three treatment groups were investigated. In the first group, pigs were conventionally housed in pens with...

  15. The effect of social dynamics and environment at time of early weaning on short- and long-term lamb behavior in a pasture and feedlot setting

    Contributor(s):: Pullin, Allison N., Pairis-Garcia, Monique D., Campbell, Braden J., Campler, Magnus R., Proudfoot, Kathryn L., Fluharty, Francis L.

    Lambs are commonly weaned around 60 d of age in the Eastern United States, but this age is also a time for lambs to apply long-term feeding strategies learned from adult animals. There is minimal evidence on how weaning strategies may affect long-term adaptation of feeding behavior. The objective...

  16. Gangs of piglets: Welfare and growth of imprinted and guided weaners

    Contributor(s):: Mesarec, Nikolina, Povše, Maja Prevolnik, Škorjanc, Dejan, Skok, Janko

    Weaning stress accompanied by outburst of aggression is a critical point in pig production as it compromises piglets’ welfare and leads to poor growth rate and health problems. Therefore, a weaning methods to smoothen the lactation–weaning transition are of great importance. In the present study...

  17. Gradual weaning during an extended lactation period improves performance and behavior of pigs raised in a multi-suckling system

    Contributor(s):: van Nieuwamerongen, S. E., Soede, N. M., van der Peet-Schwering, C. M. C., Kemp, B., Bolhuis, J. E.

    We studied effects of two weaning procedures on the development of pigs raised in a multi-suckling (MS) system with five sows and their litters. One MS group was subjected to a gradual weaning treatment during a lactation period of 9 wk, which included forced intermittent-suckling (IS) for 10h/d...

  18. Reprint of “Rearing piglets in multi-litter group lactation systems: Effects on piglet aggression and injuries post-weaning”

    Contributor(s):: Verdon, Megan, Morrison, Rebecca S., Hemsworth, Paul H.

    This experiment investigated the effects of rearing piglets in a multi-litter lactation system on piglet aggression at weaning. The following four pre-weaning treatments were applied to 72 sows and their litters (n=642 piglets); (1) Farrowing crate (‘FC’ − n=24 sows), (2) PigSAFE pens, in which...

  19. Gradually reducing sow contact in lactation is beneficial for piglet welfare around weaning

    Contributor(s):: de Ruyter, Emily M., van Wetter, William H. E. J., Lines, David S., Plush, Kate J.

    This study tested whether a gradual reduction in sow contact during lactation, achieved through housing the sow in a ‘sow only’ area, would influence piglet stress responses to weaning. Gradual reduction in sow contact was achieved by separating the sow from her piglets (SP, n=30) for 5, 7, and...

  20. A two-stage method to approach weaning stress in horses using a physical barrier to prevent nursing

    Contributor(s):: Merkies, Katrina, DuBois, Cordelie, Marshall, Kaitlyn, Parois, Severine, Graham, Laura, Haley, Derek

    Many domestic horses are weaned through abrupt physical separation of the foal and mare. Deviations from normal behaviours testify that this abrupt method has an adverse effect on the well-being of both mares and foals. To reduce negative changes in behaviour and physiology induced by weaning, a...
