Glutamic acid (Glu), alanine (Ala), serine (Ser), valine (Val), glycine (Gly), threonine (Thr), proline (Pro), aspartic acid (Asp), leucine (Leu), arginine (Arg), isoleucine (Ile), phenylalanine (Phe), histidine (His), cysteine (Cys), methionine (Met), tyrosine (Tyr), lysine (Lys). (n = 48 samples from Mediterranean chicken breeds). Asterisks indicate amino acid positively correlated (p < 0.05) with sperm viability (evaluated by propidium iodide/SYBR-14) and DNA integrity (evaluated by TUNEL).
