The bull sperm exposed to long-term stress at low (25°C) and high temperatures (45°C) has been established to show an increase in the functional groups and the pool of free amino acids in plasma. The free amino acids including asparagine, glutamine, γ-amino butyric acid, and ornithine showed increased stress reactivity at hypothermia stress while cysteic acid, glutamic acid, valine, cysteine, methionine, ethanol, isoleucine, lysine, and arginine proved to be stress resistant. The following free amino acids – serine, glutamine, proline, glycine, isoleucine, leucine, γ-amino butyric acid, lysine, and histidine showed increased stress reactivity at hyperthermia
stress, and citrulline, α-amino butyric acid, and ornithine demonstrated stress resistance. Of all the free amino acids studied, asparagines, proline, glutamine, glycine, isoleucine, and γ-amino butyric acid manifested increased stress reactivity to both hypo-and hyperthermia stress. |
