    Contributor(s):: Gouveia, K. G., Vaz-Pires, P., Costa, P. M. da

    Analysis of post mortem lesions is a common means for assessing poultry welfare during rearing and pre-slaughter handling. The aim of this study was to determine the influence of: age, sex, rearing system, total number of birds on-farm, period between catch and slaughter and distance from poultry...

  2. 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...

  3. Reducing post-mixing aggression and skin lesions in weaned pigs by application of a synthetic maternal pheromone

    Contributor(s):: Guy, J. H., Burns, S. E., Barker, J. M., Edwards, S. A.

    In commercial pig production, piglets are often mixed after weaning which can result in severe aggression and lead to body damage, disruption of feeding behaviour and reduced growth. This experiment investigated whether application of a synthetic maternal pheromone to groups of weaned pigs in...

  4. Why are sheep lame? Temporal associations between severity of foot lesions and severity of lameness in 60 sheep

    Contributor(s):: Kaler, J., George, T. R. N., Green, L. E.

    We investigated the temporal associations between the severity of foot lesions caused by footrot (FR) and the severity of lameness in sheep. Sixty sheep from one farm were monitored for five weeks. The locomotion of each sheep was scored once each week using a validated numerical rating scale of...

Observational data were collected on the standing posture, lesions on the hind left foot, and the...

  6. Is lameness a welfare problem in dairy farms with automatic milking systems?

    Contributor(s):: Klaas, I. C., Rousing, T., Fossing, C., Hindhede, J., Sorensen, J. T.

    Lameness, a disease often observed in loose-housed dairy cattle herds, affects animal welfare in general and reduces cow locomotion. As cow traffic may be affected by restricted locomotion, lameness may be a significant problem in herds with automatic milking systems (AMSs). Between January and...

  7. Relation between parity and feed intake, fear of humans and social behaviour in non-lactating sows group-housed under various on-farm conditions

    Contributor(s):: Kongsted, A. G., Hermansen, J. E., Kristensen, T.

    The number of group-housed, non-lactating sows is increasing rapidly in Europe. However, systematic information of the between-sow variation in animal welfare related factors under various on-farm conditions is lacking. Indicators of feed intake, fear of humans and social behaviour in...

  8. Wire-floor pens as an alternative to metallic cages in fattening rabbits: influence on some welfare traits

    Contributor(s):: Martrenchar, A., Boilletot, E., Cotte, J. P., Morisse, J. P.

    The possibility of improving the welfare of fattening rabbits by rearing them in pens instead of cages was investigated. Time budgets, locomotion, ear lesions, breaking strength of the femur and productivity were compared in fattening rabbits kept at the same stocking density (15 rabbits m-2)...

  9. A pilot investigation of possible positive system descriptors in finishing pigs

    Contributor(s):: Mullan, S., Edwards, S. A., Butterworth, A., Whay, H. R., Main, D. C. J.

    In this study, pig producers were identified whose practices exceeded the basic legal requirements and government recommendations for pig welfare. This novel approach was part of a larger project investigating the feasibility and benefits of the inclusion of some animalbased welfare outcome...

  10. A pilot investigation of Farm Assurance assessors' attitude to farm animal welfare as a confounding factor to training in pig welfare outcome measures

    Contributor(s):: Mullan, S., Edwards, S. A., Butterworth, A., Whay, H. R., Main, D. C. J.

    The effect of Farm Assurance (FA) assessors' attitude to farm animal welfare on the inter-observer reliability of some welfare outcome measures achieved following training was investigated as part of a larger project examining the feasibility and benefits of the incorporation of some on-farm...

  11. Can environmental variables replace some animal-based parameters in welfare assessment of dairy cows?

    Contributor(s):: Mulleder, C., Troxler, J., Laaha, G., Waiblinger, S.

    Animal-related parameters best fulfil the requirements of a valid welfare assessment, but often they are less feasible than other parameters. Therefore, this paper examines whether animal-based parameters are connected with each other and with environmental factors in order to find out if some...

  12. Comparison of the severity of esophagogastric, lung and limb lesions at slaughter in pigs reared under standard and enriched conditions

    Contributor(s):: Ramis, G., Gomez, S., Pallares, F. J., Munoz, A.

    Two hundred and ten pigs were reared in three groups (according to genotype) under enriched conditions of large open-front sawdust-bedded barns. Eight hundred and twenty pigs were reared under standard conditions of small 15-animal pens in a conventional barn with partially slatted floors and...

  13. The effects of selection on low mortality and brooding by a mother hen on open-field response, feather pecking and cannibalism in laying hens

    Contributor(s):: Rodenburg, T. B., Uitdehaag, K. A., Ellen, E. D., Komen, J.

    The aim of the present study was to investigate the effects of selection on low mortality in combination with brooding by a mother hen on open-field response at 5-6 weeks of age and on plumage and body condition at 42 weeks of age. Birds in the experiment were either selected for low mortality in...

  14. The occurrence of tail tip alterations in fattening bulls kept under different husbandry conditions

    Contributor(s):: Schrader, L., Roth, H. R., Winterling, C., Brodmann, N., Langhans, W., Geyer, H., Graf, B.

    Pathological alterations of the tail tip are a severe problem for fattening cattle husbandry with respect to animal welfare and economic losses. We compared the frequencies of tail tip lesions and less severe skin damage in bulls on farms with slatted-floor pens (slat, n=10), slatted floor pens...

  15. The welfare of finishing pigs under different housing and feeding systems: liquid versus dry feeding in fully-slatted and straw-based housing

    Contributor(s):: Scott, K., Chennells, D. J., Armstrong, D., Taylor, L., Gill, B. P., Edwards, S. A.

    Contributor(s):: Turner, S. P., D'Eath, R. B., Roehe, R., Lawrence, A. B.

    The routine mixing of pigs causes aggression that cannot be greatly reduced by low-cost environmental changes. The variability and heritability of aggressiveness are discussed and both appear adequate to make selection against aggressiveness worthwhile in grower-stage pigs. Selection would...

  19. Peripartal behaviour and teat lesions of sows in farrowing crates and in a loose-housing system

    Contributor(s):: Verhovsek, D., Troxler, J., Baumgartner, J.

    Housing of farrowing and lactating sows in farrowing crates can cause a number of welfare problems. Recently, alternative farrowing pens have been developed which allow the sow to turn around and move freely. In this experiment a conventional farrowing crate (C; 5.0 m2; the sow is crated...
