Kerbstone

Kerb height and degree of slope are important design considerations. Cows tend to prefer lying uphill and this will also allow urine and leaked milk to flow down and away from the cow.

The height of the kerbstone should be between 15-20cm. The final height of the kerb will be dictated by the method of slurry removal, although cow comfort should always be the main consideration. Although concerns have been raised about excessive kerb height, with adverse affects on foot health as a result of prolonged perching.

Scraped passages may require a slightly higher kerb to prevent faecal soiling of the beds when the passage is scraped. Slatted passages will allow the kerb to be reduced in height. The kerb height should not be reduced below 15cm, as this can encourage some cows to lie partly in and partly out of the cubicle.

When fitting mats or mattresses, it is important that their height is included in the kerb height calculation. This will help ensure that the kerb stone does not protrude above the mattress causing discomfort to the cow, on the other hand, sufficient kerb height is required to prevent mattress movement or slippage.
