  1. 1 Values are means of six replicates per treatment. Amino acid content is based on freeze-dried condition. Group C = controls, Group MM = melatonin implanted in May, Group MJ = melatonin implanted in June
  2. 2 EAA = essential amino acids
  3. 3 NAA = non-essential amino acids
  4. 4 TAA = total-amino acids
  5. a, b Mean in the same row with different superscripts are significantly different (P < 0.05)
