You might have heard about a different body condition scoring system, using a scale of 0 (“very thin”) to 5 (“obese”). This works in a very similar way, just with different numbers, with a score of 3 representing an ideal body condition (equivalent to a score of 5 in the 1-9 system). You can use whichever scoring system you feel most comfortable with, as long as you are consistent. Just remember to clarify to your vet or nutritionist, which scoring system you have used when discussing it with them!
In humans, regional fat deposition, such as around the abdomen, is more closely linked to metabolic disease (eg. Diabetes) than overall body fat. This also seems to be the case for horses, with excess fat across the neck being associated with increased circulating insulin and insulin resistance, which may increase the risk of problems, such as Equine Metabolic Syndrome (EMS) Insulin Dysregulation (ID) and laminitis. For this reason, a standardised Cresty Neck Score (CNS) has been developed for objective assessment of the neck and fat deposits that are laid down here.
It’s important to distinguish between a well-developed top line/muscly neck and one which is carrying fat so it’s vital to not only stand back and look at the horse, but also to feel and palpate the thickness and fatty deposits. Generally speaking, muscle will be harder and smooth to feel, whereas fat may be spongier.
Cresty Neck Scores (CNS) roughly correlate with BCS scores of 5 and above, however, it’s possible for a horse to have an ideal middle and hindquarters but to still have a large cresty neck. A cresty neck score of 3 out of 5, or higher, has been found to be associated with an increased risk of laminitis, so it’s important to monitor this on a regular basis, particularly in Native breeds that may be at a greater risk of developing a cresty neck. Stallions, or male horses that have been gelded late, may have “big necks” so it’s important to ensure that this smooth muscle, rather than fat.
