The normal profile of blood plasma and seminal plasma transaminases and phosphatases was studied
twice at monthly interval in 37 breeding bulls ofGir, Holstein Friesian, Jersey, Crossbred and Jafarabadi breeds.
The differences between breeds were significant (P<0.01) for only AKP and AKP:ACP ratio in blood and for all
enzymes, except GOT, in seminal plasma. The lowest and highest GOT:GPT ratio was observed in blood of crossbred and Jersey/Jafari, and in the seminal plasma of Jersey and HF/crossbred bulls respectively. Similarly, the AKP:ACP ratio in blood was lowest in Jersey and highest in Gir. In seminal plasma it was lowest in Jersey and
highest in HF/Jafari bulls. The levels oftransaminases were nearly identical both in blood and seminal plasma of
all the breeds, but AKP and ACP levels were much lower (20-20() times) with higher AKP:ACP ratios (3-7 times)
in blood than the seminal plasma of same bulls.
