New muscle wastage scoring guide aims to help monitor horse health
Based on the Muscle Atrophy Scoring System, wastage can be identified in key areas
A new equine muscle wastage scoring guide, co-developed by the SPILLERS™ brand, aims to help horse owners identify muscle wastage.
The guide is based on the Muscle Atrophy Scoring System (MASS)* published by the University of Kentucky in collaboration with the makers of SPILLERS. Using diagrams, descriptions and scores, it enables owners to identify muscle atrophy or ‘wastage’ in three key areas – the neck, the back and the hindquarters. It is suitable for all adult horses, but the SPILLERS brand hopes it will be especially valuable as a health monitoring tool for senior horses and ponies.**
Hello and welcome to Horse&Field. Our aim is to support local, grass roots equestrian enthusiasts and competitors and keep you all informed of what’s happening in the horsey world, as well as covering all things agricultural. If you haven’t already subscribed you can do so below:
“Although some degree of muscle wastage can occur with ageing, one of our more recent studies, in which we used the MASS, shows it may be exacerbated in those with an underlying clinical condition such as PPID (Cushing’s Syndrome),” said Sarah Nelson, Product Manager at Mars Horsecare, home of the SPILLERS brand. “However, the guide also provides a practical way to assess and monitor muscle loss that may occur as a result of malnutrition, injury, poor saddle fit, some forms of tying up, and certain other conditions.”
The neck, back and hindquarters are each assessed separately using one of two scales (A or B, depending on the individual's body condition) and given a score of 1-4. A score of 1 indicates no muscle wastage, whereas a score of 4 indicates severe muscle wastage.
“Ideally, horse owners and carers should monitor their horse or pony’s muscle score on a monthly basis,” said Sarah Nelson. “This tool may be useful in enabling them to notice gradual muscle deterioration, that may indicate a condition that can be addressed. Sudden or severe muscle wastage may be a sign of injury or disease, especially if it is unexpected, because there have been no changes in work, diet or management routine. It’s important for owners to discuss any concerns with their vet in the first instance.”
The muscle wastage scoring guide is the latest practical support item for horse owners to be added to the SPILLERS brand’s Weight Management Tools section of their website.
