  1. Welfare outcomes for 3- and 6-month-old beef calves in a tropical environment castrated surgically or by applying rubber rings

    Contributor(s):: Petherick, J. C., Small, A. H., Reid, D. J., Colditz, I. G., Ferguson, D. M.

    Castration of cattle using rubber rings is becoming increasingly popular due to the perceived ease of the procedure and greater operator safety when compared with surgical castration. Few comparative studies have investigated the effects of different castration methods and calf age on welfare...

  2. 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...

  3. Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth

    Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.

    Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...

  4. The ethics of a co-regulatory model for farm animal welfare research

    Contributor(s):: Phillips, C. J. C., Petherick, J. C.

    Standards for farm animal welfare are variously managed at a national level by government-led regulatory control, by consumer-led welfare economics and co-regulated control in a partnership between industry and government. In the latter case the control of research to support animal welfare...

  5. Effects of environmental enrichment for mice: variation in experimental results

    Contributor(s):: Weerd, H. A. van de, Aarsen, E. L., Mulder, A., Kruitwagen, C. L. J. J., Hendriksen, C. F. M., Baumans, V.

    This study focused on the effects of different enriched environments for mice in a number of behavioural and physiological parameters in 2 routine laboratory testing procedures: potency testing for tetanus vaccine and stress-induced hyperthermia. The variability in the results was studied by...

  6. The effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age

    Contributor(s):: Rodarte, L. F., Ducoing, A., Galindo, F., Romano, M. C., Valdez, R. A.

    Environmental enrichment can be a useful tool to reduce belly nosing behaviors in early weaned piglets. The aim of this study was to assess the effect of environmental enrichment on behavior, salivary cortisol, and productivity of piglets weaned at 14 days of age. The study assigned 112 piglets...

  7. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 2. Responses related to stress, health and productivity

    Contributor(s):: Petherick, J. C., Small, A. H., Mayer, D. G., Colditz, I. G., Ferguson, D. M., Stafford, K. J.

    Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and...

  8. Effect of gestation management system on gilt and piglet performance

    Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  9. 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

  10. Relationship between backtest and coping styles in pigs

    Contributor(s):: Spake, J. R., Gray, K. A., Cassady, J. P.

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

    Contributor(s):: Camerlink, I., Bijma, P., Kemp, B., Bolhuis, J. E.

  12. Alternative housing for sows and litters. Part 3. Effects of piglet diet quality and sow-controlled housing on performance and behaviour

    Contributor(s):: Pajor, E. A., Weary, D. M., Caceres, C., Fraser, D., Kramer, D. L.

    We studied how "sow-controlled" housing (i.e. housing where sows can leave their piglets at will) affects the behaviour and performance of sows and litters when tested under near-commercial conditions and with two different levels of piglet diet quality. Sows and litters were housed in pens where...

  13. Alternative housing for sows and litters. Part 4. Effects of sow-controlled housing combined with a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s):: Weary, D. M., Pajor, E. A., Bonenfant, M., Fraser, D., Kramer, D. L.

    Previous experimental work has shown modest and variable production and welfare benefits for the lactating sow and piglets when sows are allowed to separate themselves temporarily from their piglets, or when piglets have access to a communal creep area sufficiently attractive that they spend...

  14. Alternative housing for sows and litters. Part 5. Individual differences in the maternal behaviour of sows

    Contributor(s):: Pitts, A. D., Weary, D. M., Fraser, D., Pajor, E. A., Kramer, D. L.

    'Sow-controlled' housing has been developed to address welfare and production concerns associated with close confinement of the lactating sow and her litter, by permitting the sow to leave the litter at will. However, there is a risk that variation in the use of the piglet-free ('get-away') area...

  15. An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs

    Contributor(s):: McIntyre, J., Edwards, S. A.

    Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...

  16. Association between resting behaviour and live weight gain in dairy heifers housed in pens with different space allowance and floor type

    Contributor(s):: Mogensen, L., Krohn, C. C., Sorensen, J. T., Hindhede, J., Nielsen, L. H.

    The hypothesis that daily liveweight gain is associated with resting behaviour in heifers was studied. The study was based on 2 experiments conducted on Danish commercial dairy farms with Danish Friesian heifers (300-400 kg) in the winter periods. Group size was 5-6 heifers/pen. Experiment A,...

  17. Behavioural, endocrine and immune consequences of mixing in weaned piglets

    Contributor(s):: Merlot, E., Meunier-Salaun, M. C., Prunier, A.

    Mixing piglets at weaning increases plasma cortisol concentrations and agonistic behaviour. In contrast to what is observed in older pigs, studies failed to show any effect of social environment on other behavioural variables or on immune function. The lack of effect of mixing may not reflect an...

  18. Effect of a warm and flexible piglet nest heating system - the warm water bed - on piglet behaviour, live weight management and skin lesions

    Contributor(s):: Ziron, M., Hoy, St

    The aim of this investigation was to develop and test a new heating system for young piglets. Video observations were recorded, once a week over a 24-h period, with the help of an infrared video technique. The recordings were analysed to determine how long the piglets would remain in the nest...
