In order to improve the production profitability, research on effective and safe additives, as well as health and performance stimulators of domestic animals is becoming more and more relevant. Additives obtained from selected plants (aka phytogens: of the whole plant, extracts) have the potential to meet those demands. Although a large number of research papers on the effects phytogen additives in pig and poultry production have been published, relatively few results are available on their application and their impact on the nutrition of laying hens. This experiment was performed on the experimental farm of the Agricultural Faculty in Novi Sad (Serbia), located in Temerin. Hy-Line Brown hens were kept in a cage system. Two treatments with 6 repetitions were examined. Each treatment included 6 cages with 5 laying hens. At the beginning of the experiment the hens were 16 weeks old and the experiment lasted until they were 28 weeks of age. The following treatments were examined: 1 Control group (standard food), 2 Experimental groups: standard food + phytogen food additive (Biomin(R) PEP 125 poultry) 125 g/t of food. Group with phytogen additives achieved greater laying capacity in the 23rd week (88.9%) and 28th week (92.9%), compared with the control group (84.6% and 92.1%) as well as the average egg mass (60.2 g or 59.2 g, p is less than 0.05). Consumption of food had not changed significantly, while the feed conversion improved 4.5% for the entire experimental period.
