Electrophoretic polymorphism and activity of serum alkaline phosphatase in the ontogenetic development of piglets

Qualitative and quantitative investigations of serum alkaline phosphatase were carried out in maturing piglets. It was found that with progressing maturation of the animals the activity of the enzyme decreased and its phenotype changed. It has been demonstrated that presence of the fast fraction of alkaline phosphatase causes a significantly greater activity of the enzyme. It has been demonstrated also that in each age group differences in the activity of the enzyme observed between litters were significantly higher than those observed within litters.
