Abstract


Essential oils are intensive fragrant, oily liquid substances contained in different parts of the plant. Besides antibacterial properties, essential oils or their components have been shown to exhibit antiviral, antimycotic, antitoxigenic, antiparasitic, and insecticidal properties. In this experiment the effects of supplementation of the diet for laying hens with oregano essential oils or pollen on egg albumen physical parameters and microbiological egg parameters were studied. Hens of laying hybrid Hy-Line Brown (n=30) were randomly divided into 3 groups (n=10) and fed for 23 weeks on diets with oregano essential oil and pollen extract supplemented. In the first experimental group the feed mixture was supplemented with oregano essential oil addition in a dose 0.25 g/kg, the feed for second experimental groups of birds consisted of basal diet supplemented with pollen extract of the dose at 0.4 g/kg. The results suggest that a statistically significant difference in favor of the experimental groups compared with the control group was observed in two indicators of albumen quality. In the index of albumen and in the Haugh Units was significantly higher difference in favor of the experimental group with addition of pollen supplement (P<0.05). The highest total number of bacteria and count of coliforms bacteria was found in the control group. The number of lactobacilli was zero in all groups.The paper abstract will be written with Times New Roman 10 pt., justify. It will contain maximum 200 words. A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
