  1. Motivation for feeding in broiler breeder pullets fed different types of restricted high-fibre diets

    Contributor(s):: Riber, Anja B., Tahamtani, Fernanda M.

    High-fibre diets have been suggested as alternative feeding strategies that potentially may alleviate the hunger felt by feed-restricted broiler breeders and fulfil their behavioural need for feeding behaviour. The aim of the present study was to investigate the effects of four dietary...

  2. Preliminary investigation of social interactions and feeding behavior in captive group-housed Tasmanian devils (Sarcophilus Harrisii)

    Contributor(s):: Skelton, Candice J. A., Stannard, Hayley J.

    As the number of Tasmanian devils (Sarcophilus harrisii) in captivity increases, an understanding of captive social dynamics and behavior is becoming increasingly important. In the wild, devils are solitary, although sometimes, they congregate to feed on a large carcass. However, it is common to...

  3. The Effect of an Irregular Feeding Schedule on Equine Behavior

    Contributor(s):: Zupan, Manja, Štuhec, Ivan, Jordan, Dušanka

    We used eight horses 1 to 12 years old to investigate the influence of irregular feeding times on the behavior. The animals were housed in individual boxes, fed with hay ad libitum and barley-oat mixture at three set times; 05:00 (earlier feeding) on Thursdays, 07:00 (delayed feeding) on...

  4. Trade-offs between feeding and social companionship in cattle: Intra-animal consistency over short and extended periods

    Contributor(s):: Hirata, Masahiko, Taketomi, Ikuko, Matsumoto, Yuka, Kubo, Shotaro

    The conflict between sociability and foraging motivation in animals is considered to be of potential value for use in the management of grassland systems to improve grazing pattern of livestock over grasslands. However, individual differences in behaviors relating to this conflict have not been...

  5. Short- and long-term effects of eight enrichment materials on the behaviour of finishing pigs fed ad libitum or restrictively

    Contributor(s):: Zwicker, Bettina, Gygax, Lorenz, Wechsler, Beat, Weber, Roland

    In a semi-natural environment, a lot of the daily activity of pigs is spent in exploratory and foraging behaviour. Providing enrichment material attractive to the pigs both over the short and long term is therefore important in intensive housing systems. This study aimed to investigate the effect...

  6. Behavioural changes in dairy cows with lameness in an automatic milking system

    Contributor(s):: Miguel-Pacheco, Giuliana G., Kaler, Jasmeet, Remnant, John, Cheyne, Lydia, Abbott, Caroline, French, Andrew P., Pridmore, Tony P., Huxley, Jonathan N.

    There is a tendency worldwide for the automation of farms; this has included the introduction of automatic milking systems (AMS) in the dairy industry. Lameness in dairy cows is highly prevalent and painful. These impacts potentially affect not only animal welfare, but also farm economies. Three...

  7. Human–marmoset interactions in a city park

    Contributor(s):: Leite, Giovana C., Duarte, Marina H. L., Young, Robert J.

    Urban wildlife, frequently, comes into contact with human city dwellers and these interactions can be viewed positively or negatively by people. In the city of Belo Horizonte (Minas Gerais, Brazil) many city parks have groups of black-tufted marmosets (Callithrix penicillata), which interact with...

  8. Effects of varying feed provision on behavioral patterns of farmed collared peccary (Mammalia, Tayassuidae)

    Contributor(s):: Nogueira, Selene S. C., Calazans, Stella G., Costa, Thaise S. O., Peregrino, Hélderes, Nogueira-Filho, Sérgio L. G.

    Feeding enrichment regime has been widely employed as an important tool to mimic foraging behavior and improve farm animals’ welfare. Some authors have argued that creating some level of uncertainty in the animals’ environment is beneficial. Therefore, we evaluated the effects of challenge...

  9. Effect of enrichment on the behaviour and growth of juvenile Xenopus laevis

    Contributor(s):: Archard, Gabrielle A.

    Xenopus laevis is the most widely used model amphibian species in laboratories, yet there is almost no experimental evidence to guide best practice for captive housing. Enrichment is an important component of maintenance and welfare. A split-sibship experimental design was used to rear juvenile...

  10. Difference of social motivation in quail selected for divergent circadian activity

    Contributor(s):: Formanek, Laureline, Richard-Yris, Marie-Annick, Petton, Christophe, Houdelier, Cécilia, Lumineau, Sophie

    Endogenous rhythms are adaptive responses to predictable changes of the environment, like the day/night cycle. Some researches demonstrated that social cycles can influence the circadian rhythm, while no study investigated the effect of endogenous rhythmicity on the sociability in Vertebrates....

  11. Effects of food quantity and distribution on aggressive behaviour of gilthead seabream and European seabass

    Contributor(s):: Oikonomidou, Eleni, Batzina, Alkisti, Karakatsouli, Nafsika

    In intensive aquaculture, aggression among fish creates a disturbed social environment and leads to serious implications. Food is a resource of great importance for fish and its acquisition is an important enough reason for increased competition. Gilthead seabream Sparus aurata and European...

  12. Assessing the effect of rate and extent of starch digestion in broiler and laying hen feeding behaviour

    Contributor(s):: Herwig, Eugenia, Classen, Henry L., Schwean-Lardner, Karen V.

    Feeding behaviour can be affected by diet composition as a result of diet density, the rate and extent of ingredient digestion and the activation of nutrient sensing mechanisms. It was hypothezised that the presence of starch in the distal small intestine would activate the ileal brake, thereby...

  13. Motivation of naïve feedlot cattle to obtain grain and individual responses to novelty

    Contributor(s):: Van Os, Jennifer M. C., Mintline, Erin M., DeVries, Trevor J., Tucker, Cassandra B.

    Beef cattle may be fattened before slaughter using a high-energy, grain-based diet. Although previous research suggests cattle prefer grain, their motivation to obtain this feed has not been quantified. The objective of this study was to evaluate the motivation of naïve feedlot cattle to consume...

  14. Feeding response of marble goby (Oxyeleotris marmorata) to organic acids, amino acids, sugars and some classical taste substances

    Contributor(s):: Lim, Leong-Seng, Lai, Sian-Kang Jason, Yong, Annita Seok-Kian, Shapawi, Rossita, Kawamura, Gunzo

    Weaning from live to formulated feeds is a major challenge in the culture of marble goby Oxyeleotris marmorata. It can be solved through dietary supplementation of suitable taste substance as feeding stimulant. However, there is still no information on the suitable feeding stimulant for this...

  15. The effect of a compressed air stimulus on blocking times in a concentrate feeding station for horses in group housing

    Contributor(s):: Gülden, Aline, Büscher, Wolfgang

    Concentrate feeding stations are used to meet the different feeding requirements of group-housed horses. In practice, blocking times caused by horses remaining in the feeding station without concentrate allowance constrain the feeding process considerably. To date, the application of an electric...

  16. Aggression and social rank fluctuations in precision-fed and skip-a-day-fed broiler breeder pullets

    Contributor(s):: Girard, Teryn E., Zuidhof, Martin J., Bench, Clover J.

    In broiler breeders, conventional skip-a-day feeding leads to hunger-related aggression. As an alternative, a precision feeding system was developed to provide small meals to individual birds multiple times each day, sheltered from competition. Two objectives investigated whether: 1) aggression...

  17. Behavioural adaptation to a short or no dry period with associated management in dairy cows

    Contributor(s):: Kok, Akke, van Hoeij, Renny J., Tolkamp, Bert J., Haskell, Marie J., van Knegsel, Ariëtte T. M., de Boer, Imke J. M., Bokkers, Eddie A. M.

    From calving, dairy cows are typically milked for about a year, and subsequently managed to have a non-lactating or ‘dry period’ (DP) before next calving. However, the use of a DP may reduce cow welfare because typical DP management involves the cow changing groups and ration. Also, the DP...

  18. Effect of social feeding environment on the feeding behaviour of dairy cows and their willingness to consume a novel feed

    Contributor(s):: Mainardes, G. A., DeVries, T. J.

    Dairy cows are often exposed to novel situations and may show a strong behavioural response to novel feeds. To test the impact of social contact while feeding and the reaction of mature cows towards a novel feed we compared: 1) animals fed individually and 2) cows fed socially (in pairs). It was...

  19. The influence of sex on feeding behaviour in Pacific white shrimp (Litopenaeus vannamei)

    Contributor(s):: Bardera, Guillermo, Owen, Matthew A. G., Façanha, Felipe N., Sloman, Katherine A., Alexander, Mhairi E.

    The Pacific white shrimp (Litopenaeus vannamei) is the most cultivated species in crustacean aquaculture and a potentially important consideration for its production could be the use of monosex cultures. Generally, female penaeid shrimp are larger than males due to a greater gain in mass per...

  20. Impact of environmental enrichment and social group size in the aggressiveness and foraging activity of Serrapinnus notomelas

    Contributor(s):: da Silva, Alexandre, Lima, Marcos R., Meletti, Paulo C., Jerep, Fernando C.

    Fish are widely used in scientific research, and many species are bred for ornamental purposes and human consumption. Despite the large number of fish kept in captivity, research on the welfare of these animals has only recently intensified. One commonly used method for improving fish welfare is...
