  8. 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...

  9. A population-based on-farm evaluation protocol for comparing the welfare of pigs between farms

    | Contributor(s):: Goossens, X., Sobry, L., Odberg, F., Tuyttens, F., Maes, D., Smet, S. de, Nevens, F., Opsomer, G., Lommelen, F., Geers, R.

    The variability of animal-based parameters was studied within a population of 41 farrow-to-finish farms. Data were collected during three visits, each corresponding to a different season within a two-year period. The largest between-farm variability was observed for Stereotypic behaviour by...

  10. Application of the Welfare QualityReg. protocol at pig slaughterhouses

    | Contributor(s):: Dalmau, A., Temple, D., Rodriguez, P., Llonch, P., Velarde, A.

    The objective of the present study was to assess the sensitivity and feasibility of the Welfare QualityReg. (WQ) protocol for finishing pigs in 10 Spanish slaughterhouses. Sensitivity refers to the ability of the WQ assessment system to discriminate between slaughter conditions whilst feasibility...

  11. 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...

  12. 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...

  13. 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...

  14. Early detection of lameness in heifers with hairy heel warts using a pressure plate

    | Contributor(s):: Almeida, P. E., Mullineaux, D. R., Raphael, W., Wickens, C., Zanella, A. J.

    Lameness is an indicator of pain and suffering, which has substantial animal welfare and economic impact on the dairy industry. Subjective locomotion scoring is unreliable for detecting mild cases of lameness in dairy herds. Undetected lameness can progress to a more serious and painful state...

  15. Effects of fattening boars in mixed or single sex groups and split marketing on pig welfare

    | Contributor(s):: Boyle, L. A., Bjorklund, L.

    Our aim was to evaluate the effects of single or mixed sex fattening of boars and split marketing (SM) on pig welfare. Female (n=10), male (n=10) and mixed sex (n=10) groups were fattened to 105 kg. Two focal pigs per pen were selected for continuous behaviour observations and skin lesion...
