comparative study on the enzyme activities and some organic constituents in the seminal plasma of native breed bulls and buffalo bulls

ABSTRACT

Lactic dehydrogenase [LDH], aspartate aminotransferase, alanine aminotransferase, acid and alkaline phosphatase] and some organic constituents [fructose, total proteins, total lipids and ascorbic acid] were assessed in 200 seminal plasma samples [100 from native breed bulls and 100 from buffalo bulls]. The results showed that there are insignificant differences in the enzymatic activities of lactic dehydrogenase [LDH], aspartate-aminotransferase and alanine aminotransferase in the seminal plasma of the two species. However, the acid and alkaline phosphatase activities of buffalo bulls seminal plasma were significantly higher [P <0.05] compared to that of the native bulls. A significant increase [P <0.05] in the total proteins and fructose content of the native bulls seminal plasma than of the buffalo bulls. However, no significant differences was traced in total lipids or ascorbic acid content in the seminal plasma of the two species
