  1. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  2. Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality

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

    An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

  3. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  4. Nutrition for working and service dogs

    Contributor(s):: Wakshlag, J., Shmalberg, J.

    Conformation, genetics, and behavioral drive are the major determinants of success in canine athletes, although controllable variables, such as training and nutrition, play an important role. The scope and breadth of canine athletic events has expanded dramatically in the past 30 years, but with...

  5. Providing 'get-away bunks' and other enrichments to primiparous adult female mink improves their reproductive productivity

    Contributor(s):: Buob, M., Meagher, R., Dawson, L., Palme, R., Haley, D., Mason, G.

  6. 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

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

    Contributor(s):: Guy, J. H., Cain, P. J., Seddon, Y. M., Baxter, E. M., Edwards, S. A.

  8. The effect of cover on food consumption and growth in two freshwater fish species used in experimental studies

    Contributor(s):: Wootton, R. J., Handisyde, N., Rowe, C.

  9. Uptake and effectiveness of interventions to reduce claw lesions in 40 dairy herds in the UK

    Contributor(s):: Barker, Z. E., Wright, J. L., Blowey, R. W., Amory, J. R., Green, L. E.

  10. 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...

  11. Effect of different rearing systems and pre-kindling handling on behaviour and performance of rabbit does

    Contributor(s):: Mugnai, C., Bosco, A. dal, Castellini, C.

    The aim of this study was to ascertain how collective cage and pre-kindling handling (training does to go into their own nest) practices, in comparison to standard housing (single cage rearing), modify the behaviour and the performance of rabbit does. To this aim, 40 nulliparous New Zealand White...

  12. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal ("low")) and two...

  13. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  14. Experience of moderate bedding affects behaviour of growing pigs

    Contributor(s):: Munsterhjelm, C., Peltoniemi, O. A. T., Heinonen, M., Halli, O., Karhapaa, M., Valros, A.

    Effects of early substrate-enrichment on behaviour and productivity of pigs were evaluated in a trial with four siblings as the experimental unit. Pens either were (=E) or were not (=0) moderately bedded with wood shavings and chopped straw during suckling (0-4 weeks of age), nursery (5-9 weeks)...

  15. Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity

    Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.

    This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...

  16. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of the...

  17. The combined effects of milking frequency and feeding level on dairy goat welfare and milk emission characteristics in late lactation

    Contributor(s):: Komara, M., Giger-Reverdin, S., Marnet, P. G., Roussel, S., Duvaux-Ponter, C.

    This study investigated the combined effects of once-daily milking and feeding level (ad libitum or adjusted) on goat welfare and milk emission characteristics in late lactation. Forty dairy goats housed in individual pens were managed under twice-daily milking and fed ad libitum during a...

  18. Effects of social learning on foraging behaviour and live weight gain in first-season grazing calves

    Contributor(s):: Hessle, A. K.

    When livestock are turned out to semi-natural grasslands, an effective onset of grazing is important both for animal productivity and for defoliation of the sward, which preserve the biodiversity of the vegetation. The aim of this study was to investigate whether foraging behaviour of naive...

  19. Physiological and behavioural responses of cows from two beef breeds submitted to different suckling strategies

    Contributor(s):: Alvarez-Rodriguez, J., Sanz, A.

    This experiment was designed to study the effects of avoiding calf contact and genotype on the metabolic, behavioural and reproductive traits of beef cows during lactation. Fifty-two multiparous cows, 25 Parda de Montana (PA) and 27 Pirenaica (PI), fed at maintenance were assigned from the day...

  20. Too hungry to learn? Hungry broiler breeders fail to learn a Y-maze food quantity discrimination task

    Contributor(s):: Buckley, L. A., McMillan, L. M., Sandilands, V., Tolkamp, B. J., Hocking, P. M., D'Eath, R. B.

    Choice tests may aid determining whether qualitative dietary restriction improves the welfare of feed-restricted broiler breeder chickens (Gallus gallus domesticus). However, hunger-stress may reduce competency to choose by impairing learning. The effect of chronic feed restriction on the ability...
