Comparative activities of semicarbazide-sensitive amine oxidase (SSAO) in five domestic species.

This study compares the activity of the Semicarbazide-Sensitive Amine Oxidase (SSAO) enzyme in five different species of domestic animals – horses, camels, cattle, sheep, and goats. Researchers discovered that the enzyme activity was noticeably higher in horses compared to other animals, and that there were no significant gender-related differences in the enzyme activity. The research further revealed that the level of protein and copper is similar across all the tested species.

Objective of the Research

• The primary goal of this research was to identify the varying levels of Semicarbazide-Sensitive Amine Oxidase (SSAO) activity in five different species of domestic animals.

Methodology

• The research team gathered healthy male and female samples of five species, namely horses, camels, cattle, sheep, and goats. All the animals were born and raised in the same area to limit variability.
• The researchers measured SSAO activity spectrophotometrically using benzylamine as a substrate in the serum of the test subjects.
• On the same day, the team also collected blood from the animals to further minimize variations.
• In addition to observing SSAO activity, the researchers also measured the concentrations of protein and copper in the animals.

Findings

• The researchers determined that there were no significant differences in SSAO activity between the male and female samples of the species tested.
• They also discovered significant differences between the SSAO activities of horses compared to other studied animals.
• The study revealed that the highest SSAO activities were found in horses, followed in decreasing order by camels, cattle, goats, and sheep.
• Minor higher activities of SSAO were noted in all male subjects of the tested animals except in cattle, compared to their female counterparts.
• There were no substantial differences between the levels of proteins and copper in either sex across all the tested species.
• Overall, the results of the study suggest that horses possess a comparatively higher activity of the SSAO enzyme, about 3-21 times higher than the other species observed in the study.
