FIELD: agriculture; feed industry.
SUBSTANCE: selecting an adsorbent used in feed for farm animals, according to which samples are taken from a test feed, and the number of samples corresponds to the number of types of adsorbents, placed in separate containers and filled with a non-toxic solvent. Then, an adsorbent is added to each of the samples, with the exception of the control one, and mixed to obtain an extract. Part of the extract obtained from each sample is introduced into the nutrient solution, and they are added to each well of the aquarium with ciliates previously introduced into it. An hour later, the number of active ciliates is counted to determine the percentage of their survival and, accordingly, the toxicity of the feed sample, in which from 70 to 100% survival is non-toxic; from 40 to 69% survival is slightly toxic; 0 to 39% survival is toxic.
EFFECT: highly efficient in use.
