Can Nigerian horse owners effectively estimate body condition and cresty neck scores?

A horse's body condition impacts every aspect of its life, including reproduction, performance, and health. Obesity and equine metabolic syndrome (EMS) are common in Nigeria; hence, early identification of a horse's obesity status by the owner is key to avoiding associated health issues such as EMS. Our study aimed to determine whether horse owners could effectively estimate their horses' body condition scores (BCSs) and cresty neck scores (CNSs). A total of 50 adult sedentary West African Barb horses owned by 50 different people were enrolled in the study. Body condition scores (BCSs) and cresty neck scores (CNSs) were assessed on scales of 1-9 and 0-5, respectively, by an experienced veterinarian and owners. The latter had no veterinary background, received no prior education, and assessed their horses based on provided visual aids and descriptions. The BCS estimates of the experienced veterinarian and owners were slightly in agreement (k=0.209), while there was moderate agreement (k=0.547) between the CNS estimates of the experienced veterinarian and the owners. The proportion of obesity based on the experienced veterinarian's estimation (32%) was higher than that of the owners (18%). The proportion of nuchal crest adiposity based on the experienced veterinarian's (38%) estimation was slightly lower than that of the owners (42%). A larger proportion of the owners underestimated their horses' BCSs and CNSs. We conclude that owners cannot effectively estimate their horses' BCSs and CNSs. It is imperative that they are informed about the health issues associated with obesity and are taught how to effectively estimate BCS and CNS.
