CENTILE SCALES FOR ESTIMATING THE CONTENT OF CHEMICAL ELEMENTS IN THE FUR OF RODENTS Russian patent published in 2021 - IPC G01N33/50 

FIELD: animal husbandry.

SUBSTANCE: invention relates to agriculture, namely to animal husbandry, toxicology, may be used as a method for estimating the metabolism of chemical elements in domestic and wild animals of rodents of the Rodentia order inhabiting the Central Federal district, consisting in the fact that the content of zinc, copper, iron, lead, cadmium and arsenic is determined in the fur of rodents taken from the section of the back of the animal below the projection of the scapulae with an area of 1 cm² and a mass of 1 to 3 g, then the content of zinc, copper, iron, lead, cadmium and arsenic in the fur is estimated by the centile scales, and, if the concentration value of at least one of the above chemical elements is a centile value from 25 to 75, the level of the chemical element is estimated as normal, the centile value under 25 to 10 is estimated as below average; the centile value level above 75 to 90 is estimated as above average; the centile value under 10 to 5 is estimated as low; the centile value above 90 to 95 is estimated as high; the centile value under 5 to 0 is estimated as very low; the centile value above 95 to 100 is estimated as very high.

EFFECT: provides a possibility to increase the efficiency and accuracy of estimation of the elemental status of rodents and timely correct the imbalance of the volume concentration of chemical elements in the body of the animal.
