    Contributor(s): Andersen, Inger Lise, Tønnesen, Hege, Estevez, Inma, Cronin, Greg M., Bøe, Knut Egil

    The aim of the present experiment was to examine the effects of short-term experience with three different group sizes in an increasing and decreasing fashion on the frequency social interactions in goats. Two batches of 24 healthy, dehorned, 2–5 years old, lactating dairy goats (Capra hircus)...

  5. Relationships between scores of the feline temperament profile and behavioural and adrenocortical responses to a mild stressor in cats

    Contributor(s): Iki, Tazuko, Ahrens, Frank, Pasche, Katharina Hannah, Bartels, Angela, Erhard, Michael Helmut

    There is a growing need for an easy assessment of stress levels in cats in order to more effectively diagnose, distinguish and treat stress-related disorders or behavioural problems. Therefore, we investigated which behavioural changes might be associated with an adrenocortical response to an...

  6. Relationships between lameness and feeding behaviour in cubicle-housed Holstein–Friesian dairy cows

    Contributor(s): Palmer, Maeve A., Law, Ryan, O’Connell, Niamh E.

    The relationship between lameness and feeding behaviour in dairy cows is not yet fully understood. This study examined the effect of lameness on feeding behaviour at two points during lactation. Forty-five Holstein–Friesian dairy cows (average parity 3.3) were housed in cubicle accommodation...

  7. The relationship between the comb and social behaviour in laying hens

    Contributor(s): O’Connor, Emily A., Saunders, John E., Grist, Hannah, McLeman, Morven A., Wathes, Christopher M., Abeyesinghe, Siobhan M.

    The question of whether attributes of the combs of laying hens have any consistent relationship with dominance behaviour has yet to be answered unequivocally. This study sought to address this by investigating whether a relationship existed between the competitive ability of hens within stable...

  8. Relationship between growth rate and oral manipulation, social nosing, and aggression in finishing pigs

    Contributor(s): Camerlink, Irene, Bijma, Piter, Kemp, Bas, Bolhuis, J. Elizabeth

    Pigs may affect each other's health, welfare and productivity through their behaviour. The effect of a pig on the growth rate of its pen mates is partly heritable and is referred to as its social genetic effect. Social genetic effects, also known as indirect genetic effects, have been found in a...

  9. Relationship between backtest and coping styles in pigs

    Contributor(s): Spake, Jessica R., Gray, Kent A., Cassady, Joseph P.

    The objective of this study was to examine relationships between behaviors in three different standard tests of temperament in pigs, Sus scrofa. For the backtest, pigs (n=575) were placed in the supine position for 60s. Each pig was tested twice. Amount of time struggling and number of struggle...

  10. Regurgitation and reingestion in bonobos (Pan paniscus): Relationships between abnormal and social behavior

    Contributor(s): Miller, Lance J., Tobey, Jennifer R.

    Regurgitation and reingestion (R/R) is an abnormal behavior observed in great apes analogous to rumination syndrome in humans. A majority of the research on R/R in non-human primates has focused on gorillas and chimpanzees with little information relating to other species that also engage in this...

  11. Regrouping rabbit does in a familiar or novel pen: Effects on agonistic behaviour, injuries and core body temperature

    Contributor(s): Graf, Sylvia, Bigler, Lotti, Failing, Klaus, Würbel, Hanno, Buchwalder, Theres

    Regrouping female rabbits in group-housing systems is common management practice in rabbit breeding, which may, however, induce agonistic interactions resulting in social stress and severe injuries. Here we compared two methods of regrouping female rabbits with respect to their effects on...

  12. Reducing the incidence of net cage biting and the expression of escape-related behaviors in Atlantic cod (Gadus morhua) with feeding and cage enrichment

    Contributor(s): Zimmermann, Emily W., Purchase, Craig F., Fleming, Ian A.

    The escape of fish from aquaculture is a persistent economic problem for farmers as well as an environmental problem that threatens wild fish population as a consequence of potential negative ecological and genetic interactions. Farmed Atlantic cod (Gadus morhua) cause significant damage by...

  13. Reactivity to humans and fearfulness tests: Field validation in Polish Cold Blood Horses

    Contributor(s): Górecka-Bruzda, Aleksandra, Jastrzębska, Ewa, Sosnowska, Zofia, Jaworski, Zbigniew, Jezierski, Tadeusz, Chruszczewski, Michał H.

    The aim of the present paper was to examine in field conditions the feasibility of the experimentally developed behavioural tests for assessment of two temperamental traits of cold blood horses: fearfulness and reactivity to humans. The predictive, convergent and discriminant validity of the...

  14. Ration composition affects short-term diurnal feeding patterns of dairy heifers

    Contributor(s): Greter, Angela M., von Keyserlingk, Marina A. G., DeVries, Trevor J.

    The objective of this study was to compare the short-term (first week of adaptation to a new ration) behaviour of dairy heifers when fed a low-concentrate, high-forage ration ad libitum to when fed a high-concentrate ration in a limited amount followed by ad libitum access to straw for the...
