  1. The potential of feeding patterns to assess generic welfare in growing-finishing pigs

    Full-text: Available

    | Contributor(s):: Bus, Jacinta D., Boumans, Iris J. M. M., Webb, Laura E., Bokkers, Eddie A. M.

    The welfare of growing-finishing pigs is important inherently to the pigs, but also for the societal acceptance and environmental impact of the husbandry system. Nevertheless, methods to monitor pig welfare throughout the whole growing-finishing phase have not yet been successfully developed. One...

  2. The efficacy of novel rope flavours as environmental enrichment for stalled gilts

    | Contributor(s):: Colpoys, J. D., Johnson, A. K., Gabler, N. K.

  3. Effects of short-term exposure to drinking water contaminated with manure on water and feed intake, production and lying behaviour in dairy cattle

    | Contributor(s):: Schütz, Karin E., Huddart, Frances J., Cox, Neil R.

    This study aimed to assess the effects of water quality (contamination with manure) on water and feed intake and subsuquent milk production, and lying behaviour in dairy cattle. Fifteen lactating Holstein-Friesian cows were provided one of three water treatments in a cross-over design; clean...

  4. Early feeding experiences of piglets and their impact on novel environment behaviour and food neophobia

    Full-text: Available

    | Contributor(s):: Middelkoop, Anouschka, Kemp, Bas, Bolhuis, J. Elizabeth

    We studied whether feeding experiences of piglets during lactation influence novel environment behaviour pre-weaning and food acceptance pre- and post-weaning. In a 2 × 2 arrangement, litters (n = 10/treatment) received creep feed as monotonous diet (MO) or four feed items as diverse diet...

  5. Investigations on feed intake and social behaviour of fattening pigs fed at an electronic feeding station

    | Contributor(s):: Hoy, Steffen, Schamun, Sonja, Weirich, Carmen

    For the study from a total of 679 female pigs kept in a progeny test station in 64 groups mostly with 12 pigs each, the data from all visits at an electronic feeding station (EFS) were analysed. In 93 pigs (8 groups) all agonistic interactions at the EFS were recorded in continuous observations...

  6. Experience with a variety of feed colours reduces feed neophobia in the turkey

    | Contributor(s):: Lecuelle, Stéphanie, Leterrier, Christine, Chagneau, Anne-Marie, Laviron, Florence, Lescoat, Philippe, Bastianelli, Denis, Bertin, Aline, Bouvarel, Isabelle

    When exposed to a new feed, farm birds are commonly reluctant to eat this feed. This phenomenon, called feed neophobia, could be reduced by exposing young animals to a variety of novel feeds. We investigated whether previous experience with a variety of feed colours could reduce food neophobia in...

  7. Decision-making of goats when exposed to choice feeding: Triggered by taste or smell?

    | Contributor(s):: Scherer, R., Gerlach, K., Südekum, K. H.

    Animals recognise known forages. However, it is unclear whether recognition is mainly based on sensory characteristics linked to postingestive feedback or whether the latter is activated each time before a choice is made. Moreover, knowledge is scarce regarding the duration of the memory process...

  8. Do antiemetics attenuate the behavioural responses of sheep to simulated ship motion?

    | Contributor(s):: Santurtun, Eduardo, Navarro, Grisel, Phillips, Clive J. C.

    During actual and simulated ship transport, vessel roll (sideways) and heave (vertical) movements produce behavioural responses in sheep, typically positional and feeding changes. Antiemetics may moderate these responses, hence sheep were exposed to these two movements of similar amplitude and...

  9. Behaviour and physiology of sheep exposed to ammonia at a similar concentration to those experienced by sheep during export by sea

    | Contributor(s):: Zhang, Yu, Guinnefollau, Lauréline, Sullivan, Megan, Phillips, Clive J. C.

    Ammonia accumulates in livestock accommodation, which inflames mucosal tissue to cause coughing, sneezing and lacrimation and adversely affects feed intake. We aimed to find out why feed intake is reduced for sheep in ammonia conditions typical of live export by measuring nutritional behaviour...

  10. Dietary diversity affects feeding behaviour of suckling piglets

    | Contributor(s):: Middelkoop, Anouschka, Choudhury, Raka, Gerrits, Walter J. J., Kemp, Bas, Kleerebezem, Michiel, Bolhuis, J. Elizabeth

    Stimulating solid feed intake in suckling piglets is important to facilitate the weaning transition, exemplified by the positive correlation between pre- and post-weaning feed intake. The present study compared the effect of dietary diversity (i.e. offering two feeds simultaneously) and flavour...

  11. Energy intake and expenditure of improvised explosive device detection dogs

    | Contributor(s):: Phillips, S. P., Kutzner-Mulligan, J., Davis, M.

    Improvised explosive device detection (IDD) dogs explore up to 40 km of land daily and therefore have energetic demands that may be above the National Research Council's requirement for working dogs. This study was designed to quantify metabolic energy intake (MEI) and total energy expenditure...

  12. Feeding behavior and the effect of photoperiod on the performance and hematological parameters of the pacama catfish (Lophiosilurus alexandri)

    | Contributor(s):: Kitagawa, A. T., Costa, L. S., Paulino, R. R., Luz, R. K., Rosa, P. V., Guerra-Santos, B., Fortes-Silva, R.

    The aim of this study was to evaluate the rhythms of feeding and locomotor activity, the ability to synchronize to a fixed feeding time, and the influence of photoperiod on the growth parameters, feed intake and hematological parameters of a recently introduced fish in freshwater Brazilian...

  13. The effect of presenting forage in multi-layered haynets and at multiple sites on night time budgets of stabled horses

    | Contributor(s):: Ellis, A. D., Redgate, S., Zinchenko, S., Owen, H., Barfoot, C., Harris, P.

    The aim of this study was to explore the efficacy of multi-layered haynets and multiple presentation of haynets to increase time spent on feed intake behaviour at night (13 h observation). For preliminary assessment two horses performing the oral stereotypy of crib-biting were included. Six...

  14. Understanding feeding patterns in growing pigs by modelling growth and motivation

    | Contributor(s):: Boumans, I. J. M. M., Bokkers, E. A. M., Hofstede, G. J., Boer, I. J. M. de

    Feeding is an essential behaviour for body maintenance in pigs and closely related to their growth and productivity performance. Mechanisms underlying feeding behaviour in pigs are still unclear. Understanding these mechanisms can provide valuable insights into the complex interactions among...

  15. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Full-text: Available

    | Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  16. Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females

    | Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.

    An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...

  17. Effect of feed allowance at pasture on lying behaviour and locomotory ability of dairy cows

    | Contributor(s):: O'Driscoll, K., Lewis, E., Kennedy, E.

    In temperate climates where cows are primarily managed at pasture shortages of grass could result in nutritional deficits for the cow and thus pose a challenge to her welfare. This study investigated the effect of daily herbage allowance (DHA) on dairy cow lying behaviour, locomotory ability, and...

  18. Effect of forage presentation on feed intake behaviour in stabled horses

    | Contributor(s):: Ellis, A. D., Fell, M., Luck, K., Gill, L., Owen, H., Briars, H., Barfoot, C., Harris, P.

    In some stabled horses, the lack of foraging opportunity leads to a reduction in chewing time with consequent negative impacts on the digestive system and potentially development of stereotypies. This study aimed to compare the effect of four types of haynets on feed intake behaviour in stabled...

  19. Feed-restricted broiler breeders: state-dependent learning as a novel welfare assessment tool to evaluate their hunger state?

    | Contributor(s):: Buckley, L. A., Sandilands, V., Hocking, P. M., Tolkamp, B. J., D'Eath, R. B.

    This paper reports three experiments that aimed to validate the use of state-dependent learning (SDL) as a novel welfare assessment tool to evaluate the hunger state of feed-restricted broiler breeders. In each experiment, birds alternated every 2 days between two food rations: quantitative feed...
