Metalothionein synthesis in pigs at diet contamination by cadmium and lead at phone of sorbents using

The 60-day experiment on krossbreed hogs with combinative contamination of diets by 2MPC cadmium and 2MPC lead at phone use of various doses highdispersed (1-6 mcm) shungite and zeolite is conducted. Maximal growth of living mass had hogs which fed base diet - 33,9±3,05 kg (biological control). Contamination of diet by 2MPC cadmium and 2MPC lead initiates increase 0f metalothionein synthesis to 45,9%. The decrease of productivity in that case composes 13,8% and feed expenditure increases to 15,9%. Combined using of shungite and zeolite in doses 1-2% of diet did not prevent negative action of cadmium and lead - productivity decreased to 8,8-9,2%. Use of sorbents in such doses allows to minimise influence of cadmium and lead on animal organism, but do not guarantees prevention of metalotoxicosis.
