The objective of the examinations was to establish the parameters of blood mineral components, glucose and proteins in Polish ponies in the four seasons of the year. The examinations were done on 66 females, 20 stallions and 4 geldings at the age over 1.5 year. Blood was examined each season for 2 years. Variations were found in the content of K, Mg, Ca, P, Cl, Fe, glucose and total proteins. A more accurate evaluation of the results of the examinations of those blood parameters is possible when seasonal variations are taken into consideration.
