Observations on hematological and biochemical markers in gallus domesticus, consecutive fooder supplementation with organic selenium

Selenium prevents the formation of free radicals. Haematologically, selenium has an important role in protecting haemoglobin against peroxidising. In the present study 20 laying chickens of the Rosso breed were subjected to the experiment, being divided into two batches. The experimental batch was given feed diet 21/5 for laying hens together with 6 grams/kg M.F. (mixed fodder) Sel-PlexTM, while to the control batch was given the same feed diet but without the added selenium. Before the start of the experiment as well as 30 days after, biological samples were collected and used to determine hematological and biochemical parameters. The results were bio-statistically interpreted. In the experimental batch significant growths were observed for the erythrocyte parameters: erythraemia, haemoglobinemya, haematocrite, MCV and MCH. Of the biochemical markers, significant growths were observed in the ascorbinemic acid, lipids and serum pseudocholinesterase. The following parameters dropped significantly, proteinemia and blood
