FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to feeding of mammals. Composition, containing triglycerides with middle chain length (MCT), in efficient amount for prevention, reduction or retardation of one or several cognitive functions, motor activity, cerebrovascular function, or behaviour of healthy ageing mammal, applied in dose 1-2 g MCT/kg of body weight/day, which increases concentration of at least one ketone in blood flow, where MCT has formula: 
where R1, R2 and R3 each, independently, are esterificated with glycerol skeleton fatty acids, which have 5-12 carbon atoms; and where said ageing animal reached, at least, approximately 50% of its expected life span. Methods of prevention, reduction or retardation of aggravation of, at least one of cognitive functions, motor activity, cerebrovascular function, or behaviour of healthy ageing mammal includes introduction of claimed composition in dose1-2 g MCT/kg of body weight/day.
EFFECT: invention ensures improvement of said functions in ageing animals.
