METHOD FOR EXPRESS EVALUATION OF FEED TOXICITY AND FULL MIXED DIET FOR FARM ANIMALS Russian patent published in 2023 - IPC A23K10/00 A23K20/00 A23K50/00 G01N33/00 G01N33/02 

FIELD: agriculture.

SUBSTANCE: method for rapid assessment of the toxicity of the basic forage and a fully mixed diet for farm animals is proposed, according to which a feed sample is averaged, a sample is taken from it and mixed with acetone, then intensively mixed until an extract is obtained. The extract is filtered or centrifuged, separating the supernatant, neutralizing it and mixing with the nutrient medium. The resulting mixture is introduced into the well of the aquarium with ciliates previously placed in it in an amount of 10 to 20 pcs. An hour later, the number of active ciliates is counted to determine the % of their survival and, accordingly, the toxicity of the feed sample, at which more than 70% survival is a non-toxic sample; from 40 to 69% survival - slightly toxic; less than 40% survival - toxic.

EFFECT: improving the efficiency of assessing the toxicity of feed.
