ABSTRACT. Experimental results of the effect of natural mineral sorbent- feed additive white mud (WM), on production of poultry were presented. The object of the study was broilers of the IZA-F-15 cross-breed and laying hens of the Hisex White cross-breed. Previously conducted evaluation of the ability of the studied substance to absorb my-cotoxins T-2, aflatoxin B1, ochratoxin A from aqueous solutions, and fat-soluble vitamins A and E, as compared to samples of activated carbon and hydrolytic lignin, showed that along with the sorption leaders, WM has a less distinct potential to bind toxins, but at the same time the percentage of binding important biologically active substances, vitamin A and vitamin E, was minimal. It was found that the inclusion of SB in diet of the broiler chickens promoted an increase of their body weight, achieving a substantial statistically significant superiority in this parameter by the end of fattening. At slaughter results it was established that chickens fed the sorption fodder had statistically higher indices of eviscerated carcass weight as compared with the controls. The use of the additive in diet of industrial laying hens in the second phase of production resulted in an increase of egg-laying intensity not only during its use (411-441 days), but also in the next two months of the technological cycle. The use of SB additionally to the main diet of laying hens had a beneficial effect on the strength and thickness of the shell, as well as on the height of the egg white. The chemical analysis of bones revealed a statistically significant increase in calcium level and the upward trend in the level of phosphorus in experimental chickens, indicating activation of calcium-phosphorus metabolism in laying hens that is very important for industrial hens when the egg production fall below 90% (the second phase of productivity).

KEYWORDS: feed additive with sorption properties, broiler chickens, laying hens, poultry meat and egg productivity.
