Hubungan Polimorfisme Gen Hormon Pertumbuhan MspI dengan Bobot Badan dan Ukuran Tubuh Sapi Pesisir Sumatera Barat (The Relationship of MspI Growth Hormone Gene Polymorphism and Body Weight and Body Measurements of West Sumatera Pesisir Cattle)

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 measurements. It was concluded that the MspI polymorphism could not yet be used as a marker for body weight and body measurement of Pesisir cattle.
