Abstract

Donggala cattle (Bos indicus) are one of Indonesian native cattle from Central Sulawesi that kept for meat production purpose. This study aimed to observe the genetic diversity of Protamine 1 (PRM1) gene of Donggala bulls using a sequencing method. A total six Donggala bulls from the breeding station (UPTD Pembibitan Sapi Potong Provinsi Sulawesi Tengah) were used in the present study. The results showed that a novel missence mutation of p.R25I (Arginine &#8594- Isoleucine) was detected in the PRM1 gene (exon 1) of Donggala bulls. In this study, two bulls have the heterozygous RI genotype and the another bulls have a normal (RR) genotype. While, the mutant genotype (II) was absence in the animals study. However, the many sperm qualities of volume, motility and concentration in RR bulls were higher than RI bulls but not different significantly. In conclusion, the I allele may be had the negative impact on sperm quality of Donggala bulls. Hence, the further study with large samples is important to confirm this finding accurately.
