    Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.

    Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...

  3. Food puzzles for cats: feeding for physical and emotional wellbeing

    Contributor(s):: Dantas, L. M. S., Delgado, M. M., Johnson, I., Buffington, C. A. T.

    Practical relevance: Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health issues, such as chronic lower urinary tract signs, and...

  4. Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans

    Full-text: Available

    | Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.

    Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...

  5. Influences on the avoidance and approach behaviour of dairy goats towards an unfamiliar human - an on-farm study

    | Contributor(s):: Mersmann, D., Schmied-Wagner, C., Nordmann, E., Graml, C., Waiblinger, S.

    The human-animal relationship (HAR) is an important factor for successful animal husbandry and animal welfare. Thus, the HAR is included in on-farm assessments to evaluate overall welfare. For dairy goats, validated tests to assess the HAR are lacking. The aim of the present study was to evaluate...

  6. Does group size have an impact on welfare indicators in fattening pigs?

    | Contributor(s):: Meyer-Hamme, S. E. K., Lambertz, C., Gauly, M.

    Production systems for fattening pigs have been characterized over the last 2 decades by rising farm sizes coupled with increasing group sizes. These developments resulted in a serious public discussion regarding animal welfare and health in these intensive production systems. Even though large...

  7. An investigation into the feeding behaviour and diet selection of the domestic horse

    | Contributor(s):: Marie Clare Cairns

    This study sought to investigate feeding behaviour and diet selection of horses exposed to concentrate feed of differing flavours and nutrient contents in different situations. Firstly behaviour was studied in a simple choice test. The results showed that when thehorses have no previous...

  8. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto-Juniperus oxycedrus woodland

    | Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  9. Validation of HOBO Pendant data loggers for automated step detection in two age classes of male turkeys: growers and finishers

    | Contributor(s):: Dalton, H. A., Wood, B. J., Dickey, J. P., Torrey, S.

    Activity levels can be used as a predictor of health status, physical condition, feed efficiency, and coping style in animals. Small, portable data loggers have been validated as an inexpensive and effective alternative to video or live observation for automated activity detection in several...

  10. Prevalence of stereotypies and its possible causes among captive Asian elephants ( Elephas maximus) in Tamil Nadu, India

    | Contributor(s):: Vanitha, Varadharajan, Thiyagesan, Krishnamoorthy, Baskaran, Nagarajan

    Animals in captivity are often confined in small barren enclosures, preventing adequate exercise, and socialization with conspecifics. Captivity is also known for depriving young individuals' association with maternal relatives by weaning away from their mothers' earlier than what their peers...

  11. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    | Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  12. The relationship between individual behavioural styles, dominance rank and cortisol levels of cats living in urban social groups

    | Contributor(s):: Finkler, H., Terkel, J.

    Individual animals show differences in temperament, often correlated with ecologically important behavioural patterns such as dominance, and with physiological responses to environmental perturbations, such as cortisol levels. Identifying these temperaments in animals may reveal adaptive patterns...

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

    | Contributor(s):: Ash, H., Buchanan-Smith, H. 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,...

  14. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    | Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

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