New Animal-Based Measures to Assess Welfare in Dromedary Camels

Abstract

Reliable and measurable animal-based measures (ABMs) are essential for assessing animal welfare. This study aimed at proposing ABMs for dromedary camels identifying their possible associations with management. Data were collected at a permanent camel market; a total of 76 pens and 528 camels were evaluated. ABMs were collected for each welfare principle (i.e. Good feeding, Good housing, Good health, Appropriate behaviour), while resources or management-based measures were collected at three levels of investigations (Animal, Herd or Caretakers). Associations were calculated by Generalized Linear Models. Body Condition Score and Thirst index (ABMs of Good feeding) resulted negatively associated with short caretaker’s experience, dirty bedding, limited shaded space, feeding and water space, and space allowance (P<0.05). Resting behaviours and Restricted movements (ABMs of Good housing) were associated with short caretaker’s experience, dirty bedding and water, rationed water distribution, water points in the sun, and presence of hobbles (P<0.05). Disease, Injury, and Pain induced by management procedures (ABMs of Good health) were negatively associated with short caretaker’s experience, presence of hobbles, limited space allowance and shaded space, dirty bedding, and feeding and watering practices (e.g. frequency of distribution, resource quality, location of the troughs)(P<0.05). Response to Approaching test and Aggressivity (ABMs of Appropriate behaviour) were negatively associated with limited space allowance, shaded, feeding and water space, and rationed water distribution (P<0.05). Overall, the proposed ABMs seems to be appropriate indicators of welfare consequences in camels being able to identify factors related to housing and management practices that may impair or improve camel welfare.
