  1. A plea to implement robustness into a breeding goal: poultry as an example

    Contributor(s):: Star, L., Ellen, E. D., Uitdehaag, K., Brom, F. W. A.

    The combination of breeding for increased production and the intensification of housing conditions have resulted in increased occurrence of behavioral, physiological, and immunological disorders. These disorders affect health and welfare of production animals negatively. For future livestock...

  2. A review of environmental enrichment for pigs housed in intensive housing systems

    Contributor(s):: de Weerd, H. A. van, Day, J. E. L.

    This paper critically reviews the literature concerning environmental enrichment for weaner, grower and finisher pigs housed in intensive (indoor) production systems. The thesis of our review is that successful enrichment should meet four criteria of success: (1) it should increase...

  3. Achieving optimum performance in a loose-housed farrowing system for sows: the effects of space and temperature

    Contributor(s):: Baxter, E. M., Adeleye, O. O., Jack, M. C., Farish, M., Ison, S. H., Edwards, S. A.

    Piglet survival relies on interactive influences of the sow, her piglets and their environment. There are a number of design challenges in a loose-housed farrowing and lactation system to optimise this dynamic, including achieving farrowing in the desired location (i.e. a protected nest area) and...

  4. Aggression in replacement grower and finisher gilts fed a short-term high-tryptophan diet and the effect of long-term human-animal interaction

    | Contributor(s):: Poletto, R., Meisel, R. L., Richert, B. T., Cheng, H. W., Marchant-Forde, J. N.

    Aggression can be a major problem for swine production as it negatively impacts the pigs' health and welfare. Increasing tryptophan (TRP) intake to raise brain serotonin (5-HT) - key for aggression control, and long-term positive social handling can reduce stress in pigs. Objective was to...

  5. An exploratory study on the effects of a straw dispenser in farrowing crates

    | Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.

    The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...

  6. Assessing the effects of a chronic stressor, stocking density, on welfare indicators of juvenile African catfish, Clarias gariepinus Burchell

    | Contributor(s):: Nieuwegiessen, P. G. van de, Boerlage, A. S., Verreth, J. A. J., Schrama, J. W.

    Fish welfare is an area of increasing interest and stocking densities used in commercial aquaculture have been highlighted as a subject of specific welfare concern. The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...

  7. Assessment of acute pain experienced by piglets from ear tagging, ear notching and intraperitoneal injectable transponders

    | Contributor(s):: Leslie, E., Hernandez-Jover, M., Newman, R., Holyoake, P.

    Suckling piglets are routinely identified to assist with their day-to-day management. A total of 120 suckling piglets were used to determine and compare the short-term pain responses to a number of identification methodologies, including: ear notching, ear tagging and intraperitoneal injection...

  8. Assessment of animal welfare in 80 dairy cow herds in cubicle housing # animal health and other animal-related parameters

    | Contributor(s):: Rouha-Mulleder, C., Palme, R., Waiblinger, S.

    Introduction: With growing concerns about farm animal welfare (e.g. by consumers; WILDNER, 1998), knowledge about the actual situation with regard to animal welfare on farms is important. Valid assessment of animal welfare requires the use of animal-based parameters, while environmental...

  9. Assessment of sheep welfare using on-farm registrations and performance data

    | Contributor(s):: Stubsjoen, S. M., Hektoen, L., Valle, P. S., Janczak, A. M., Zanella, A. J.

    Farm animal welfare is a societal concern, and the need exists for scientific protocols to assess welfare. This paper describes the development of a protocol to assess the welfare of sheep (Ovis aries) and its application in 36 farms in Norway. There were two parts to the protocol; the animal-...

  10. Associations between lesion-specific lameness and the milk yield of 1,635 dairy cows from seven herds in the Xth region of Chile and implications for management of lame dairy cows worldwide

    | Contributor(s):: Green, L. E., Borkert, J., Monti, G., Tadich, N.

    Lameness is one of the greatest infringements of welfare in dairy cows. The objective of this study was to investigate associations between milk yield and foot lesions causing lameness in Chilean dairy cattle with the hypothesis that if we can demonstrate that lameness reduces yield, and so...

  11. Assurance schemes as a tool to tackle genetic welfare problems in farm animals: broilers

    | Contributor(s):: Cooper, M. D., Wrathall, J. H. M.

    Farm assurance schemes can set standards to assure compliance with specific requirements relating to animal welfare. As such, standards can be set to address genetic-related welfare problems in farm animals, such as those associated with fast growth rates in meat chickens (broilers) (Gallus...

  12. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    | Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

  13. Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type

    | Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.

    Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...

  14. Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs

    | Contributor(s):: Wall, D., Paterson, B., Mohan, R.

    Behaviour of juvenile mud crabs, Scylla serrata (70-90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better understand the role that...

  15. Behaviour of pre-pubertal gilts and its relationship to farrowing behaviour in conventional farrowing crates and loose-housed pens

    | Contributor(s):: Ison, S. H., Wood, C. M., Baxter, E. M.

    Individual variation in the reproductive performance of sows has the potential for greater negative impacts in loose-farrowing systems. Therefore, the ability to select gilts that will perform well would be a major advantage. This study investigated the behaviour of gilts during pre-pubertal...

  16. Breeding for better welfare: genetic goals for broiler chickens and their parents

    | Contributor(s):: Dawkins, M. S., Layton, R.

  17. Consistency and influence on performance of behavioural differences in Large White and Landrace purebred pigs

    | Contributor(s):: Fernandez de Sevilla, X., Casellas, J., Tibau, J., Fabrega, E.

    According to the theory of behavioural strategies, individual animals show clear consistency when they have to adapt to environmental changes and challenges: their responses are predictable in different situations and throughout time. The main objective of this research was to evaluate...

  18. Culled early or culled late: economic decisions and risks to welfare in dairy cows

    | Contributor(s):: Langford, F. M., Stott, A. W.

  19. Economic evaluation of high welfare indoor farrowing systems for pigs

  20. Effect of different free stall surfaces on behavioural, productive and metabolic parameters in dairy cows

    | Contributor(s):: Calamari, L., Calegari, F., Stefanini, L.

    Two experiments were carried out on 56 lactating dairy cows in an experimental free stall barn comparing four different lying surfaces: straw bedded pack (ST), rubber mat (RM), mattress (MA) and sand (SA). In the first experiment (26 days) cows were allowed to choose between free stalls with each...
