As a result of the monitoring it was determined that the greatest problem while forming the balanced diet for pigs was the issue with raw fiber and raw protein. 25% of diets for weaning piglets and 35% of diets for piglets at growing didn't meet the norms on raw fiber and 20,25% - on raw protein. The zinc and copper microelements concentration in diets for pigs of different sex and age groups came out to be the most variable. The zinc variability index was 17,1-30,3%, and copper - 14,8-22,7%. Periodicity of monitoring of raw fiber and raw protein content in diets should be higher for piglets of early age; and microelement content (calcium and phosphorus) - for single, pregnant and lactating sows
