The influence of administering "effective microorganisms" to pullets on chosen haematological and biochemical blood indexes.
"Effective Microorganisms" (EM)--a mixture of lactic acid bacteria, photosynthetic bacteria, yeasts and fungi are used mainly in agriculture and organic waste treatment. Recently, they have also been added to water and feed for animals, as well as to processing their excrements into compost and to eliminate the stench. The objective of the present study was to assess the influence of a 14-day administration of an EM solution in drinking water to layer hens on chosen haematological and biochemical indexes. The research was carried out on 120 hens divided into two equal groups. The birds in the experimental group were given drinking water with dissolved EM (5% solution), and those in the control group--water without the preparation. On the 64th day of the aviculture, the hens were weighted and their blood was taken from the wing vein for haematological and biochemical examinations. Administering EM with water to hens did not influence significantly their body weight nor chosen haematological and biochemical indexes. A significant increase was found only in the number of platelets, the level of albumins, the content of total cholesterol and the LDH activity, however, a decrease in the ALT activity was observed.
