  5. Early social experiences do not affect first lactation production traits, longevity or locomotion reaction to group change in female dairy cattle

    Contributor(s):: Valníčková, Barbora, Šárová, Radka, Špinka, Marek

    Under natural conditions cows and their calves live together. In dairy practice, calves are separated from their mothers within hours after birth and then housed individually. This study investigated the effects of the presence of the dam during the colostrum feeding period and subsequent group...

  6. Stress, the HPA axis, and nonhuman primate well-being: A review

    Contributor(s):: Novak, Melinda A., Hamel, Amanda F., Kelly, Brian J., Dettmer, Amanda M., Meyer, Jerrold S.

    Numerous stressors are routinely encountered by wild-living primates (e.g., food scarcity, predation, aggressive interactions, and parasitism). Although many of these stressors are eliminated in laboratory environments, other stressors may be present in that access to space and social partners is...

  7. Predicting feather damage in laying hens during the laying period. Is it the past or is it the present?

    Contributor(s):: de Haas, Elske N., Bolhuis, J. Elizabeth, de Jong, Ingrid C., Kemp, Bas, Janczak, Andrew M., Rodenburg, T. Bas

    Feather damage due to severe feather pecking (SFP) in laying hens is most severe during the laying period. However, SFP can develop at an early age and is influenced by early rearing conditions. In this study we assessed the risk factors during the rearing and laying period for feather damage at...

  8. Mother rearing of dairy calves: Reactions to isolation and to confrontation with an unfamiliar conspecific in a new environment

    Contributor(s):: Wagner, Kathrin, Barth, Kerstin, Hillmann, Edna, Palme, Rupert, Futschik, Andreas, Waiblinger, Susanne

    The aim of this study was to test the effects of mother rearing on behavioural and physiological stress reactions of calves in challenging situations. Thus, we compared mother-reared and artificially reared calves that were kept in the same group but with varying contact with adults....

  9. The effect of rearing environment on feather pecking in young and adult laying hens

    Contributor(s):: Gilani, Anne-Marie, Knowles, Toby G., Nicol, Christine J.

    Although the rearing period has an important influence on the development of feather pecking in laying hens, few studies have quantified the risk factors operating on commercial farms during this time and identified their long-term impact. Our aim was to conduct a longitudinal study to...

  10. Integration into the dairy cow herd: Long-term effects of mother contact during the first twelve weeks of life

    Contributor(s):: Wagner, Kathrin, Barth, Kerstin, Palme, Rupert, Futschik, Andreas, Waiblinger, Susanne

    The objective of this study is to investigate the long-term effects of mother rearing on the ability to cope with the challenge of integration into the cow herd shortly before first parturition. Four groups of heifers with different levels of contact with their mothers during the first twelve...

  11. Early rearing interacts with temperament and housing to influence the risk for motor stereotypy in rhesus monkeys (Macaca mulatta)

    Contributor(s):: Vandeleest, Jessica J., McCowan, Brenda, Capitanio, John P.

    Laboratory and zoo housed non-human primates sometimes exhibit abnormal behaviors that are thought to reflect reduced well-being. Previous research attempted to identify risk factors to aid in the prevention and treatment of these behaviors, and focused on demographic (e.g. sex or age) and...

  12. Access to litter during rearing and environmental enrichment during production reduce fearfulness in adult laying hens

    Contributor(s):: Brantsæter, Margrethe, Tahamtani, Fernanda M., Nordgreen, Janicke, Sandberg, Ellen, Hansen, Tone Beate, Rodenburg, T. Bas, Moe, Randi Oppermann, Janczak, Andrew Michael

    Exaggerated fear-reactions are associated with injurious flying, smothering, feather pecking and other events that compromise animal welfare in laying hens. The aim of this study was to test the hypothesis that chicks with access to litter during the first five weeks of life would be less fearful...

  13. Contact with cows during the young age increases social competence and lowers the cardiac stress reaction in dairy calves

    Contributor(s):: Buchli, Cornelia, Raselli, Alice, Bruckmaier, Rupert, Hillmann, Edna

    Separating calf and cow within 24h after birth is common practice in dairy farms. Some dairy farmers, however, practice a rearing system in which the calves are nursed by their dam or by foster cows. We investigated if dairy calves reared in such a system (calves with cow-contact) differ in their...

  14. Effects of enrichment on the development of behaviour in an endangered fish mahseer (Tor putitora)

    Contributor(s):: Ullah, Imdad, Zuberi, Amina, Khan, Kifayat Ullah, Ahmad, Shahzad, Thörnqvist, Per-Ove, Winberg, Svante

    Structural enrichment in the rearing environment, not only promotes fish welfare, but also affects several aspects of behavioural biology of fish in aquaculture. Here an attempt was made to use physical-enrichment to improve the behaviour of hatchery-reared fish. In this study, three groups of...

  15. Rearing environment and laying location affect pre-laying behaviour in enriched cages

    Contributor(s):: Hunniford, Michelle E., Widowski, Tina M.

    The number of eggs laid in a nest is often correlated with nest acceptance and therefore hen welfare. However, evaluating pre-laying behaviour may more accurately reflect welfare independent of egg location. Our objective was to compare the effect of rearing environment and laying location on the...

  16. The long-term impact of infant rearing background on the affective state of adult common marmosets (Callithrix jacchus)

    Contributor(s):: Ash, Hayley, Buchanan-Smith, Hannah M.

    Early life environment, including temporary family separation, can have a major influence on affective state. Using a battery of tests, the current study compared the performance of adult common marmosets (Callithrix jacchus), reared as infants under 3 different conditions: family-reared twins,...

  17. Responses of dams versus non-nursing cows to machine milking in terms of milk performance, behaviour and heart rate with and without additional acoustic, olfactory or manual stimulation

    Contributor(s):: Zipp, Katharina A., Barth, Kerstin, Rommelfanger, Eike, Knierim, Ute

    There is increasing interest in dam rearing where dairy cows are milked and nurse their calves additionally. One shortcoming in dam rearing is the impaired alveolar milk ejection, which lowers the milk yield obtainable by machine milking. In this study dams and non-nursing dairy cows were...

  18. The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition

    Contributor(s):: Norman, Kate I., Weeks, Claire A., Pettersson, Isabelle C., Nicol, Christine J.

    In commercial situations, laying hens must negotiate levels to reach resources such as food, water and litter. Providing ramps in aviary systems reduces collisions and resultant keel bone fractures in adults. We investigated whether providing ramps during rear improved the ability of birds to...

  19. Behavioural responses to cow-calf separation: The effect of nutritional dependence

    Contributor(s):: Johnsen, Julie Føske, Mejdell, Cecilie M., Beaver, Annabelle, de Passillé, Anne Marie, Rushen, Jeffrey, Weary, Daniel M.

    There is increasing interest in keeping dairy cows with their calves during the milk feeding period, and in reducing distress associated with separation. The aim of this study was to investigate how nutritional dependence upon the cow's milk affects behavioural responses to separation by both the...

  20. Reduced locomotor play behaviour of dairy calves following separation from the mother reflects their response to reduced energy intake

    Contributor(s):: Rushen, Jeff, Wright, Rebecca, Johnsen, Julie Føske, Mejdell, Cecilie Marie, de Passillé, Anne Marie

    Play behaviour is an indicator of good welfare in young calves and is reduced by low energy intake and weaning off milk. There is renewed interest in keeping calves longer with the cow but separation leads to signs of distress, such as vocalizations. Providing calves with an alternative milk...
