BENEFITS OF TEAS AND PROBIOTIC PROFILE AT SPECIFIC STAGES OF EMBRYONIC DEVELOPMEN IN CHICKEN EGGS

Introduction: The Sharr Mountain is characterized by a highly expressed biological diversity, with a particular endemism and a wide spectrum of various types of flora characteristic of this mountainous massif. Plants with nutritional and health benefits can be considered species such as: mountain tea (Sideritis scardica) and St. John's wort (Hypericum perforatum), etc. These bioproducts are characterized by special importance both in terms of their presence, quality, and health benefits. Therefore, exploration of these species would have positive cost for consumption as forms of teas or plant extracts for commercial purposes, but also for health benefits and above all for the population of the country, the region, and beyond. Research Objective: This study aims to investigate the probiotics and the effect of plant extract teas such as mountain tea (Sideritis scardica) and St. John's wort (Hypericum perforatum) by applying a specific dose of extract to chicken embryos at different stages of ontogenesis. Materials and Methods: Fertilized chicken eggs were taken for the study and were incubated in an incubator for 21 days. The eggs were treated with species such as mountain tea (Sideritis scardica) and St. John's wort (Hypericum perforatum) at certain stages of embryonic development. The eggs were opened on the seventh, fourteenth, and twenty-first day. Macroscopic and microscopic changes at certain stages of embryonic development were analyzed using stereomicroscope.The effect of the extract of these teas was studied on the chicken embryos (Gallus domesticus), by applying a specific dose of extract to the chicken embryos at different stages of embryonic development during ontogenesis. Research Results: The dose given in the form of extract has resulted in positive benefits of these teas as effective probiotics during certain stages of embryonic development in chicken embryos. Conclusions: This research will explore the effect of the given dose of plant extracts at certain stages of embryonic development during ontogenesis to observe the benefits of dose administration at specific quantities and times to detect the positive effect of these teas.
