Abstract
This study was aimed to study the relationship of MspI growth hormone (GH) gene and body weight and
body measurements of West Sumatera Pesisir cattle. A total of 123 Pesisir cattle, originated from Pesisir
Selatan (91 heads) and Padang Pariaman district (32 heads) was analyzed. The results showed that the
frequency of CC, CT and TT genotype were 0.05, 0.30 and 0.65 respectively. The allele frequency of C and
T were 0.2 and 0.8 respectively and the PIC value was 0.267. The results of t test among genotype showed
that the MspI growth hormone polymorphism did not significantly affect the body weight and body measure-ments.
It was concluded that the MspI polymorphism could not yet be used as a marker for body weight and
body measurement of Pesisir cattle.
