Genetic parameters for CPL in Belgian Draught Horses

Chronic progressive lymphedema (CPL) occurs in several draught horse breeds, like the Belgian Draught Horse. In the lower limbs slight to severe swelling occurs with progressively deteriorating skin lesions and deformation.

The results show that skinfold thickness and hair diameter cannot be used as a direct diagnostic for CPL, since they were highly correlated. The heritability of CPL is relatively low. Advised is to select on estimated breeding values based on repeated clinical examinations to reduce CPL occurrence in the Belgian Draught Horse.

Expert opinion by Anouk van Breukelen

In this study permanent environmental effects, like the date of measuring, were shown to be highly important, which was not shown in earlier study. For future data collection, continued measurement is advised.
