Abstract

This paper presents the result of the study made on the dynamic response of camels' heart rate (HR) under working conditions. The main objective was to develop a simulation model that can describe the dynamic nature of the camels' heart rate response to physical activity i.e. pulling a loaded cart and sledge. The dynamic simulation model was developed using Powersim simulation software.The model verification and validation processes indicated that the model could describe the basic pattern of camels' dynamic heart rate response to physical activity. The coefficient of determination. R(2), was more than or equal to 0.74 for seven of the eight data sets used for model development. This basic profile of the dynamic response of camels heart rate had four parts: resting condition (before activity); transient; steady state; and recovery conditions. The heart rate rose rapidly, maintained steady state and then decreased gradually after the release of load. The statistical test indicated that the difference in animals (p<0.0001), loads (p<0.0001), and loading types (p<0.0006) had significant effect on the HR response of experimental camels.
