to help reduce the risk of sand colic by monitoring sediment levels

Colic is one of the most common emergency problems in the horse and has many different causes, one of which can be sand in the horse’s gut. Animals ingest it as they graze and it can accumulate in the colon over time. Here it irritates the gut lining and, in sufficient quantity, also has the ability to cause impactions which, if not treated in time, can be fatal.

To help horse owners to identify whether their equine is at risk, postal test specialists Westgate Labs, have added a faecal sand test to their range of easy to use, evidence based test kits.

Consultant vet to Westgate Labs, Carolyn Cummins MVB Phd MRCVS commented:

“Horses presenting with sand colic usually have a history of grazing on sandy soils, drinking from natural water courses, being kept on restricted grazing or fed in a ménage.  For equines in these situations a faecal sample can be taken at intervals through the year and checked for sand to assess the levels in the gut.

“Test results from Westgate are expressed as a percentage to give a quantitative measure of the level found. While it’s not desirable to find any sand in faeces, some healthy horses are not affected by a small amount. For this reason positive tests should be discussed with your vet on a case by case basis. Together you can determine whether other symptoms such as diarrhoea/colic are also present and devise an appropriate management and/or treatment protocol.”

With the variables of gut movement it is possible for the test to generate a false negative and show no sand in the faeces of horses that are carrying a burden. For this reason the Westgate test includes two sample kits; if no sand is detected in the first sample then a second can be taken a few days later.

Alternatively if sand is detected then the second can be used to retest the horse following management adjustments. Abdominal ultrasound and X-rays can also be used to detect sand in the gut, although X-rays may not be easy in larger horses and require a powerful machine.

Director of Operations at Westgate, Kristy Hodgson said:

“The test itself is a simple sedimentation technique which horse owners can of course conduct at home. We have introduced this service in response to requests from customers who would prefer to send their samples to the laboratory. Conducting them in the lab enables us to generate a consistent quantitative result so that levels can be easily monitored over time.”

Where sand is present in the dung a variety of management changes can be introduced with the aim of reducing sand levels in the horse.

Regular testing along with management changes will help to monitor the sand levels in the gut and manage the risk of colic. Owners should always consult their vet if they have any health concerns about their horses.
