    Contributor(s):: Stadig, Lisanne M., Rodenburg, T. Bas, Ampe, Bart, Reubens, Bert, Tuyttens, Frank A. M.

    Automated tracking of the location of individual chickens is becoming more common in behavioural research. This technology has several advantages including gathering large amounts of data and monitoring of individual animals as opposed to flocks. To ensure the quality of the research the...

  5. Sexual behaviour in sheep is driven by body condition and the related nutritional and metabolic status

    Contributor(s):: Alhamada, Moutaz, Debus, Nathalie, González-García, Eliel, Bocquier, François

    To evaluate the effects of nutrition on the sexual behaviour of ewes, forty-eight mature (7.6±1.9years old) Merino d’Arles ewes with an average initial body condition score (BCS=2.26±0.23) and similar body weight (BW=46.6±3.8kg) were fed three contrasting diets for three months. The diets...

  6. Short- and Long-Term Effects of Unpredictable Repeated Negative Stimuli on Japanese Quail's Fear of Humans

    Full-text: Available

    | Contributor(s):: Agathe Laurence, Sophie Lumineau, Ludovic Calandreau, Cécile Arnould, Christine Leterrier, Alain Boissy, Cécilia Houdelier

    Numerous aversive events occur in poultry production, and if repeated and unpredictable, can result in an impaired welfare. Some events such as handling can be perceived negatively and it is of interest to understand how humans' behaviour could affect poultry's behaviours and especially...

  7. Evaluation of the Prevalence and Risk Factors for Undernutrition in Hospitalized Dogs

    Full-text: Available

    | Contributor(s):: Jenifer Molina, Marta Hervera, Edgar Garcia Manzanilla, Carlos Torrente, Cecilia Villaverde

    Hospitalized dogs are predisposed to undernutrition, which can potentially affect outcome. This study evaluated the prevalence of undernutrition in hospitalized dogs (measured as loss of body condition score, BCS and body weight, BW) and studied the risk factors that affect nutritional status,...

  8. Maximum permissible load for Kiso horses trotting over a short, straight course

    | Contributor(s):: Matsuura, A., Inoue, S., Irimajiri, M., Hodate, K.

  9. The influence of human behaviors in the increased prevalence of overweight dogs

    | Contributor(s):: Nora J. Nealon, Julie M. Fagan

    An increasing number of dogs are falling into the overweight and obese categories, paralleling the rise in obesity over the past few decades in people. This suggests that dogs, which interact closely with people, have been influenced by our sedentary lifestyles, over-sized portions and diets high...

  10. 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...

  11. Effects of carprofen, meloxicam and butorphanol on broiler chickens' performance in mobility tests

    | Contributor(s):: Hothersall, B., Caplen, G., Parker, R., Nicol, C. J., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.

    Lame broiler chickens perform poorly in standardised mobility tests and have nociceptive thresholds that differ from those of non-lame birds, even when confounding factors such as differences in bodyweight are accounted for. This study investigated whether these altered responses could be due to...

  12. Maximum permissible load for Yonaguni ponies (Japanese landrace horses) trotting over a short, straight course

    | Contributor(s):: Matsuura, A., Mano, H., Irimajiri, M., Hodate, K.

    This study aimed to determine the load-bearing capacity of trotting Yonaguni ponies using gait analysis. The Yonaguni pony is one of the Japanese landrace horses, and has normal gait characteristics when trotting. As a breed they are small in stature and hence susceptible to the effect of the...

  13. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    | Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  14. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    | Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...

  15. 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...

  16. Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy

    | Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.

    This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...

  17. Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality

    | Contributor(s):: Muns, R., Manteca, X., Gasa, J.

    An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

  18. Head partitions at the feed barrier affect behaviour of goats

    | Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.

    Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...

  19. Predicting time spent on different behavioural activities from physicochemical properties of fibrous diets in finishing pigs

    | Contributor(s):: Bakare, A. G., Ndou, S. P., Madzimure, J., Chimonyo, M.

    The objective of the present study was to predict time spent on different behavioural activities by finishing pigs, using physicochemical measurements of fibrous feed. Eighty four Large White * Landrace barrows with 80.54.7 kg body weight (BW) at the beginning of the experiment were used. Feed...

  20. Early human handling in non-weaned piglets: effects on behaviour and body weight

    | Contributor(s):: Oliveira, D. de, Costa, M. J. R. P. da, Zupan, M., Rehn, T., Keeling, L. J.

    Early handling of animals including tactile stimulation (TS) has been shown to have beneficial effects on the physical and psychological development of species where considerable maternal interaction, e.g. in the form of licking, already occurs. But little is known about the magnitude of these...
