Abstract


The objective of the study was to know the association between genetic
variations at growth hormone loci and growth (meat production) of Indonesian local
cattle (Madura, Bali and Ongole derived (PO) cattle). PCR-RFLPs were applied for
the detection of DNA polymorphism at locus I and ll of growth hormone gene, and
the result indicated that polymorphisms were found at both loci usingAIul and Mspl
enzymes. Association between genotype variations and growth trait was analysed
using two models of Anova implemented in a program of INIP. The preliminary
analysis indicated that the Mspl genotypes at locus II of the gene to be associated
with growth (daily gain) of PO cattle, but not for locus I detected using AluI.
