Impact of lameness on gait characteristics and lying behaviour of zero grazed dairy cattle in early lactation
Contributor(s):: Blackie, Nicola, Bleach, Emma, Amory, Jonathan, Scaife, Jes
The present study examines the impact of lameness on the time budgets and gait of dairy cattle during early lactation. Automated assessment of activity together with an objective method (using video motion analysis) of assessing the gait of the cattle was utilised. Twenty-five Holstein dairy cows...
The effect of lameness on lying behaviour of zero grazed Holstein dairy cattle
Contributor(s):: Blackie, Nicola, Amory, Jonathan, Bleach, Emma, Scaife, Jes
The present study examines the impact of chronic lameness, where animals remained the same locomotion score for 3 consecutive months on lying behaviour of dairy cattle. The 59 lactating Holstein dairy cows recruited to the study, were grouped according to locomotion score (LS) where low scores...
Avoidance-related behavioural variables and their relationship to milk yield in pasture-based dairy cows
Contributor(s):: Dodzi, Madodana S., Muchenje, Voster
The behavioural responses of Jersey, Friesland and crossbred cows to humans were determined by recording their avoidance distance scores (AD), exit speed (ES), pen score (PS), pen behaviour score (PBS), platform score (PLS), and the occurrence of kicking (KCK) and stepping (SPG) during milking in...

Animal welfare: establishing a dialogue between science and society. (Special Issue: Knowing animals.)
Contributor(s):: Miele, M., Veissier, I., Evans, A., Botreau, R.
Farm animal welfare has become an important issue for the European public, especially in the last two decades when a number of crises (eg Bovine Spongiform Encephalopathy and Avian Influenzalu) have affected farm animal populations. Public concern about this issue led the European Union to fund...
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...
Effect of training on the inter-observer reliability of lameness scoring in dairy cattle
Contributor(s):: March, S., Brinkmann, J., Winkler, C.
In the present study, the effect of training on inter-observer reliability was studied for a 5-category lameness scoring system used for routine on-farm surveys of welfare in dairy cattle. The inter-observer agreement between an experienced and an initially inexperienced observer was determined...
Reliability of a subjective lameness scoring system for dairy cows
Contributor(s):: Brenninkmeyer, C., Dippel, S., March, S., Brinkmann, J., Winckler, C., Knierim, U.
Four observers were trained in lameness assessment using a subjective scoring system with five categories, and observer agreement was investigated four times at different stages of training and experience. Inter-observer reliability increased with time and reached acceptable levels in the last...
Welfare assessment on Japanese dairy farms using the Animal Needs Index
Contributor(s):: Seo, T., Date, K., Daigo, T., Kashiwamura, F., Sato, S.
The Animal Needs Index (ANI) is used for on-farm assessment of welfare in Austria. However, no synthetic welfare assessment system exists in Japan. We performed a welfare assessment of Japanese dairy farms using the ANI scoring system. On 25 farms, 36 dairy herds were assessed using the...
