Kolesnichenko V. Biogenic migration of mercuric compounds in the system soil-water-feeds-body of layers

3.The background, content of mercury in soil, water, feeds, body of layers has been established.Biogenic migration of mercury in the system ' soil-water-feeds-body' of layers has been noted.The analysis of pectin-containing preparation influence on mercuric compounds concentration in organs and tissues of productive layers has been given.Using pectin-containing preparation made on the base of husks of grapes (95%), which contain considerable amount of ascorbic acid ( 4%) and activated charcoal ( 1%) promotes taking mercury out of the layer's body up to 45-67% at in the investigated groups as compared with that of the control ones.While using the preparation there has been noticed the tendency to increasing the following indices in the investigated poultry groups : egg-yields of the layers were increased by 3.27-9.88%; biological value of the meat was improved and protein-qualitative index of the meat showed the increase by 0.3% as compared with the same indices in the control group.The recommendations on using pectin substances from wastes of poultry production have been developed.The patent for the invention № 34330 А ' Feed additives for poultry ' has been given.
