Abstract

Acute behavioural and physiological responses of sheep to S/C ivermectin injection

Highlights

Ivermectin is a member of the macrocyclic lactones widely used as a broad-spectrum drug against a wide range of endo- and ectoparasites in ruminant animals (Gokbulut et al, 2008; Jameel et al, 2014)
It is well established that the preferred site for S/C injections in sheep is the skin just behind the elbow; In Egypt, the preference of S/C injection at the neck region over that behind the elbow is a common trend among veterinarians without a well-established scientific basis
This investigation sheds light on the potential difference between S/C injections at the neck region versus behind the elbow manifested by modulations in acute behavioural patterns and stress endpoints measured as a reflection of animal welfare

Summary

Introduction

Ivermectin is a member of the macrocyclic lactones widely used as a broad-spectrum drug against a wide range of endo- and ectoparasites in ruminant animals (Gokbulut et al, 2008; Jameel et al, 2014) It is commercially available in different formulations including injections, oral, and rumino-reticular and cutaneous delivery systems (Mestorino et al, 2003). It is well established that the preferred site for S/C injections in sheep is the skin just behind the elbow; In Egypt, the preference of S/C injection at the neck region over that behind the elbow is a common trend among veterinarians without a well-established scientific basis This investigation sheds light on the potential difference between S/C injections at the neck region versus behind the elbow manifested by modulations in acute behavioural patterns and stress endpoints measured as a reflection of animal welfare
