This study focuses on the problem of assessing inter-observer reliability (IOR) in the case of dichotomous and four-level animal-based welfare indicators, using and comparing the performance of the agreement indexes available in literature. Udder asymmetry was evaluated as a dichotomous variable in 160 dairy goats by three observers (A, B and C). As four-level variables, Earposture (EP) and Eyewhite (EW) were scored by two observers from 436 photos of dairy cows during the lactating (L) and dry (D) periods

Abstract
This study focuses on the problem of assessing inter-observer reliability (IOR) in the case of dichotomous and four-level animal-based welfare indicators, using and comparing the performance of the agreement indexes available in literature. Udder asymmetry was evaluated as a dichotomous variable in 160 dairy goats by three observers (A, B and C). As four-level variables, Earposture (EP) and Eyewhite (EW) were scored by two observers from 436 photos of dairy cows during the lactating (L) and dry (D) periods
