The paper presents the study results of the isotherms of nitrogen adsorption-desorption on blue and green powdered clays before and after the surface is modified with solutions of organic acids (oxalic, succinic) and sodium carbonate. Unlike powder of natural blue clay, the material of green clay is characterized by the presence of macropores (5%) with a diameter of more than 50 nm; 95% of volume is occupied by mesopores ranging in size 4-40 nm. According to the size distribution data, the total number of mesopores of blue and green clays has reduced after treatment with oxalic acid; it changes slightly after introduction of alkaline compound into system (sodium carbonate, 10 wt %). It was revealed that the process of adsorption of total impurity ingredients of fatty acid triglycerides provides the possibility of using acid-modified clays with a set of properties (specific surface area, pore distribution) after processing for 1 hour in sunflower oil to stabilize the digestive function of the gastrointestinal tract of poultry and improve the quality of eggs laid by them by daily evening introduction into the feed (1-3 wt %) for 1 month prior to laying.
