BMC Veterinary Research

Table 2 Indicators in the AWI of the "Social interactions" category and the definitions used for rating and their maximum individual score.

¹Animal Weight Unit (AWU); 1 AWU = 500 kg live weight. X² represents the observed value (X) between 2 and 3 m²/AWU. In tether systems, the first figure refers to back and forth movements, the second to lateral movement. a). Refers to the space allowance; only one type of system is scored; if different systems were found on-farm, each system must be scored independently b). Family herd consist of suckler cows with male and female calves, heifers and steers of the same family and integrated bulls. The total social interactions score (column 1) equals to the sum of columns a). b). c). d). e). f). and g).
