Immune status of young pigs under the influence of midium preparation

The efficiency of midium biological active fodder supplement during growing of young pigs was investigated. The live mass and hematological indices in different ages animals were determined in connection with dose of added midium to basic ration. The immune status of piglets depending on duration of preparation treatment was estimated. It was shown, that addition of midium preparation in dose of 15 g/kg of dry ration matter during 1 month and also in doses of 10 and 15 g/kg during 4 months promotes to the increasing of average daily live weight gain in pigs without negative influence on animals immune system.
