Each row indicates the percentage of spermatozoa in each sperm subpopulation. Cluster; sum of percentage for each extender = 100, and species = 100. Total number of cells for each extender: OptiXcell® = 2666, Triladyl® = 1606, Tris-EY = 2221. Total number of cells for each species: Bos taurus = 2395, Bos indicus = 4098. a, b, c, d Superscript indicates differences within row regarding sperm subpopulation. α, β, γ Superscript indicates differences within column for each extender; δ, ε Superscript indicates differences within column for each species; chi squared (χ2) test, p < 0.05.
