“…L. plantarum exhibits enzymatic properties which can reduce the number of pathogenic microorganisms, including Candida Albicans, Candida Enteritis, Shigella, Salmonella, Listeria etc. (Alvarez, 2019;Gupta & Ayan, 2019). L. plantarum is stable at high temperatures (98 ºC) and high acidity (pH 1.2-2.0) (Andrade et al, 2019;Vaziri et al, 2019;Shah et al, 2020), which allows to use them as in vivo transporting agents of therapeutic compounds or proteins (Niedzielin et al, 2001).…”

“…Normal intestinal microflora forms a relatively stable system in animals and birds (Mehdi et al, 2013;Alvarez, 2019), but nutrient deficiencies that occur during intensive farming and various environmental stressors can upset the balance of the system (Alvarez, 2019;Andrade et al, 2019;Gupta & Ayan, 2019). Therefore, one of the effective ways to preserve the qualitative and quantitative composition and biochemical activity of normal microflora is the use of diets enriched with lactobacilli, which prevent the development of diseases and activate the immune response.…”

Modern industrial poultry farming occupies a leading position in the production of dietary foods, for which it is appropriate to use biologically active substances and probiotics. The study compared the effectiveness of compound feed with the addition of sodium selenite, bio-nano-selenium and L. plantarum in terms of body weight, weight gain, feed consumption and safety of experimental quail. The quails of the Pharaoh meat breed were kept in the vivarium of Bila Tserkva National Agrarian University and by the method of analogues were divided into 4 groups - control and three experimental ones. The duration of the study was 35 days. The results of the study indicate that the use in the quail’s diet of probiotics (L. plantarum) and selenium preparations (sodium selenite and bio-nano-selenium) leads to a predominance of poultry experimental groups in live weight over control analogs. It was found that the growth of bird’s live weight during the experiment differed depending on the use of the Selenium medication or probiotic, and the most intense effect on live weight of quails was the use of bio-nanоselenium in the diet of poultry (11.8% at the end of the experiment). Changes in absolute and average daily body weight gains of experimental birds have been clarified. The use of sodium selenite in the diet of quail caused a tendency for an increase in gains compared with control analogs at the beginning of the study and a downward trend during the fifth week of the study. It was found that the use of probiotics and bio-nano-selenium caused an increase in quail growth, which was more pronounced and reliable when feeding bio-nano-selenium. The obtained results show that probiotic and selenium preparations reduce feed consumption by 1 kg of weight gain, body weight increase by 3.05–11.8% and by 3.3–6.6% increase the safety of the experimental livestock with the best indicators in the group, receiving bio-nano-selenium.
