BALANCE OF HEAVY METALS IN THE COURIER'S ORGANIZATION AFTER THEIR SALT OF SILICON MINERAL WATER TREATMENT

Abstract.

The results of investigations on the balance of lead, cadmium, zinc and copper in the body of redbred chickens are presented for the introduction of a silicon-mineral extract in their diet. The level of contamination of poultry meat, produced in conditions of intensive farming, where there is a significant pollution of soils with harmful substances, in particular heavy metals, is studied. One of the most powerful sources of soil contamination with heavy metals is mineral fertilizers, the volume of which in Vinnytsia region has increased by 2.8 times in recent years. Under these conditions, the quality and safety of cultivated crop production and feed materials produced from it are substantially reduced. It was established that the introduction of the kpemnievo-mineral extract in the diet of chickens by replacing 10% of their daily water rates contributed to an increase in the intensity of withdrawal from their organism following the lead by 27.5 pp, cadmium 30.2 pp, zinc 20 pp and copper at 16.3 pp Thus, for the slaughter of young birds during 130 days of siliceous mineral extract, the concentration of lead decreased in white meat by 1.1 times, in red meat 1.02 times and in the liver 1.6 times. The concentration of cadmium in the poultry meat of the experimental group was 1.6 times lower, 1.8 times in red meat and 1.2 times in the liver. The zinc content in the poultry meat of the experimental group was 1.05 times lower, 1.8 times in red meat and 1.3 times in the liver. The concentration of copper in white meat was 1.3 times lower, in meat red in 1.4 times, and in the liver 1.3 times. Consequently, the introduction of a silicon mineral extract into a ration of birds by replacing 10% of the daily water rate made it possible to reduce the concentration of cadmium and lead in meat to the MAC. A noticeable reduction of lead, cadmium, zinc and copper in poultry meat for the introduction of silicon-mineral extraction into its diet was also detected. In particular, the concentration of lead, cadmium, zinc and copper in red meat decreased by 1.02 times, 1.8, 1.8 and 1.4 times, respectively. In white meat, the concentration of lead decreased by 1.1 times, cadmium in 1.6 times, zinc in 1.05 times and copper in 1.3 times
