PC-Horse report significant quotas for relevant nutrients. Many calls for advice on what should be a desirable quotas. Tables for UK and Ireland below compiled by Dr. Dag Austbø, who is Professor in animal nutrition with horses as a speciality.
Units:
Energy: MJ digestible energy (MJ DE)
Protein: Crude protein (CP)
Ca: Kalcium
P : Phosphorous
Comments:
● CP/MJ ratio should not be below the recommended values. Moderately higher values represent normally no problem.
● Ca/P ratio should not be below the recommended values and not be higher than 2,0. *The high recommended ratio for Light Work is meant for horses that come into training from a maintenance or convalescent state.
Recommended values in the UK and Ireland:
