Influence of the phytosorption complex on the content of heavy metals in products

Abstract

 The base of the complex consists of three carefully selected sorbents: perlite, polyphepan and vermiculite. The phyto components were used from previously conducted tests both in vivo and in vitro: thyme herb, chamomile  flowers, elecampane rhizomes and root, wormwood, juniper berry oil and oregano oil. The research was carried out in the Smena agricultural enterprise in the Pushkinogorsk district of the Pskov region. For this purpose, the monitoring of the content of heavy metals in the soil and the main feed of the diet of calves 2 months of age was carried out. Were selected 10 animals, with the same conditions of keeping and feeding.  One  group of animals served as a control (n = 5), in the second group, in addition to the diet, a phytosorption complex was added at a dose of 4% of the main diet. The experiment lasted 14 days. At the end of the experiment, the animals were slaughtered and samples of muscle tissue and parenchymal organs were taken to determine the amount of heavy metals.  The presence of heavy metals was determined by the periodate method and  by the method of atomic adsorption spectrometry. An experiment on the effect of the phytosorption complex on the accumulation of heavy metals in the organs and tissues of animals showed that the content of cadmium in the muscle tissue of calves in the experimental group was less by 25%, in the liver by 28.5%, in the kidneys by 52%, compared with the control. This experiment showed the prospects of introducing a phytosorption complex into the diets of farm animals to obtain environmentally friendly products. Along with this, it is necessary to monitor the environment and draw up specific feed additives, sorption complexes and recommendations for their use for each disadvantaged  area.
