NEW METHODS FOR DETOXIFICATION OF HEAVY METALS AND MYCOTOXINS IN DAIRY COWS

Abstract

Among the many environmental and industrial factors that adversely affect the soil, the pollution with heavy metals and mycotoxins occupies a special place in livestock breeding. This study aimed to demonstrate methods of treating and pharmacological correction of a toxic state intensified by heavy metals and mycotoxins in cattle using native drug as mycotoxin-deactivating feed additive. A total of 20 highly productive Holstein cows aged 3-4 years were divided into 2 groups, based on clinical and biochemical parameters. The experimental group (n=10) fed a diet supplemented with 4% sorption complex and a drug based on Silybum marianum and ursodeoxycholic acid as a hepatoprotector named “Hepaton-vet”. The control group (n=10) was injected with a complex of sorbents (consisting of perlite, vermiculite, and polyphepan in equal proportions) at a dose of 4% of the daily intake of food, and the rest of the treatment was carried out with the help of daily infusion therapy. So in the feed samples, only the T-2 and Deoxynivalenol (DON) indicators exceeded the normal value by 1.66% and, 3%, respectively. Thus, the practical efficiency concerning T-2, aflatoxin and Deoxynivalenol were to 100%, 86%, 18%, respectively. Cadmium in compound feed was lower by 44%, in comparison with the maximum permissible concentration, followed by 53.3% in hay and 78% in silage. The amount of lead in compound feed and silage was 78%, and it was 35% in the hay. In conclusion, the use of a complex of sorbents, together with newly developed component “Hepaton-vet”, led to positive results, allowing for the identification of several effects that influenced the metabolic processes in the liver, which was confirmed by the results of morpho-biochemical blood tests and clinical diagnostics of the animals' condition.
