The increase in bodyweight in kilograms per day used as a measure of growth rate in young horses. For example, an ADG for a 6-month-old Thoroughbred foal might be of the order of 0.75kg/Day declining to 0.5 kg/Day at age 12 months. Graphs of bodyweight and ADG may be used to ensure growth rate is appropriate for the age of foals and weanlings. ADG is driven primarily by carbohydrate, and to a lesser extent protein intake. Regular weighing of foals and weanlings is useful to monitor ADG and growth rate so as to avoid too rapid growth which predisposes to DOD/OCD
