Abstract
Background and Aim:
Madura cattle is local cattle in Indonesia. This cattle hasphenotypic variations in growth traits. This study aimed to identify leptin (LEP) gene polymorphism exon 2 associated with body measurements in Madura cattle.
Materials and Methods:
We recorded body weight (BW) and body measurements of 51 Madura cattle aged 1-4 years in Waru District, Madura. The LEP gene genotyping was conducted using the polymerase chain reaction-restricted fragment length polymorphism method with AciI restriction enzyme.
Results:
A 267 bp DNA fragment of the LEP gene was successfully amplified using a pair of primers. This study revealed three genotypes (TT, TC, and CC) and two alleles (T and C). The frequencies of TT, TC, and CC genotypes were 0.275, 0.45, and 0.275, respectively, whereas the frequencies of T and C alleles were 0.500 and 0.500, respectively. The c.73T>C mutation was significantly associated with BW, body length (BL), and chest girth (CG) (p<0.05). Among all genotypes, the TC had the highest BW, BL, and CG.
Conclusion:
Conclusively, LEP gene polymorphism (c.73T>C) exon 2 was polymorphic and associated with body measurements, especially BW, BL, and CG.
