Abstract

Blood plasma samples from 60 indigenous cattles were collected from the provinces of Batangas, Laguna, Cavite, and Sorsogon. Starch gel electrophoresis was used to analyze protein polymorphism.The analysis revealed eight presumptive loci, namely: Alb, with only one genotype AA, Trf, with three genotypes AC, BB, BC; Est1, with genotype AA; Este, with genotypes AA, AB, BB; Est3, with genotype AA; Acphi and Acph2, both with genotypes AA, AB, BB; and MDH, with genotypes AA, AB, AC, BB. All loci are polymorphic except for Alb, Est,, and Est3. Cavite cattle population had the highest average heterozygosity (0.536). All four cattle populations have the same high proportion of polymorphic loci (0.625). Average number of alleles per locus ranged from 1.0 — 1.15, respectively. Interpopulation variability showed that the highest genetic identity (0.9597) was between Laguna and Batangas indicating that their cattle population are the most genetically related. The highest genetic distance (0.2327), on the other hand, was recorded between Sorsogon and Cavite.
