The bibliometric analysis was conducted to determine the impact of enriched-selenium yeast supplementa-tion in sheep diet. The objective of this paper is to evaluate the dietary organic selenium on metabolic stress as well as the blood metabolites in sheep. Thirty female Pelibüey and Dorper sheep were used during a fat-tening period (60 days) of an average age of 6-8 months old. The basal diet was corn, cookie ground, sor-ghum, distillers dried grain (DDG), oat, and molasses-based diet with 3.1 Mcal/kg weight and combined with 10.16% of crude protein. Animals were randomly divided into 3 groups (10 animals per group): Con-trol group (T1, basic diet with no additive), T2, fed with the basal diet with a 0.3 mg Se/kg (Saccharomyces cerevisiae); and T3, fed with the basal diet with a Se 0.60 ppm. Experimental results were compared with the bibliometric indicators collected from 2010-2014 for a density-equalizing mapping. Data were retrieved from Scopus. Red blood cell count, hematocrit, hemoglobin, white blood cells, and red blood cell indices mean globular volume (VGM) and concentration hemoglobín globular mean (CHGM) were higher for treatment with a lower concentration of Se (T2, 0.3 ppm). A total of 3 countries contributed papers from the top 8 most cited papers about Selenium in the diet of sheep. All countries are from the developed world with a high degree of production and healed care. In conclusion, Supplementation with selenium-enriched yeast at a ratio of 0.3 ppm did not affect hematological variables and improved red cell life even before slaughter. Manuscript profile
