Abstract

The F94L mutation of the MSTN gene (MSTN-F94L) is considered not to cause disrupted the function of the myostatin gene drastically. Interestingly, this mutation has a very significant effect on muscle mass, carcass, or meat yield and meat quality without any associated severe negative problems. This study aimed to confirm the MSTN-F94L mutation in four local cattle breeds in Indonesia. A total of 518 individuals (140 of Bali, 107 of Sumbawa, 168 of Pasundan, and 103 of Holstein-Friesian (H-F) cattle) were used in this study. Genotype identification was performed by PCR-RFLP method. In the present study showed that the wild-type C allele was fixed (1.000) in Bali, Sumbawa, and HF cattle. However, the wild-type C allele and the mutant A allele were found in Pasundan cattle, even though the frequency of the mutant A allele was very low (0.012). Therefore, in conclusion, the mutation of the MSTN-F94L was detected in Pasundan cattle but no in all three cattle breeds. However, the presence of the mutant A allele in Pasundan cattle allegedly derived from Limousin bulls. The further investigation in other local and exotic breeds and its crossing will answer the status of the MSTN-F94L mutation in local cattle breeds in Indonesia.

Abstract

Growth hormone gene that controls metabolism and body size of animals and polymorphism of the gene is known related to performance of livestock. Identification of gene polymorphisms was important to get early information to determine genetic markers associated with economically desirable traits. Genetic mapping is one of important characterizations in the selection process. Pesisir cattle is one of local cattle in Indonesia that are reared in West Sumatera and have become adaptive to local environment. The present study aimed to identify the genotype of Growth Hormone gene (GH891│MspI) of the Pesisir cattle and crossbred Simmental-Pesisir cattle (designated as SimPes) and relationship between growth performance (body weight and body size). The present study was conducted to 30 blood samples consisted of 15 Pesisir cattle and 15 SimPes cattle. Body weight and body size were measured at 12-18 months of age. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method was used in this research. The results showed that there exist three variant genotypes (MspI-/-, MspI+/-, MspI+/+) and that allele frequencies of MspI- and MspI+ were 53.3% and 46.7%, respectively. Non-significant effect has found between GH’s genotype and growth traits (Body measurement and body weight) in both of breed cattle. In conclusion, three variant genotypes (GH891│MspI) in Pesisir and SimPes (Simmental x Pesisir) cattle population were found and no significant effect on growth trait performance.

Abstract

Caseins are milk protein subdivided into four main groups which are αS1, αS2, β-casein and kappa-casein (CSN3). Kappa-casein gene influences the manufacturing of milk properties. The aim of this study was to identify the kappa-casein gene polymorphism in Friesian Holstein (FH) cattle. Fifty nine (59) samples consisted of 32 (Malang), 10 (Sukahati Bogor) and 17 (Research Center for Biotechnology-Indonesian Institute of Sciences’s collections)were applied in this study. DNA samples were extracted by high concentrated NaCl and quantified by spectrophotometer. The kappa-casein gene was amplified at 379 bp fragment by PCR method using a pair primer of kappa-casein at 56oC annealing for 30 cycles. PCR-RFLP technique with HindIII was used for genotyping analysis. The result showed that there were three variants of genotypes (AA, AB and BB) in two populations from Malang and RC for Biotechnology-LIPI’s collection while cattle from Sukahati had only AA and AB genotypes. The averages of genotype frequencies were 65.28%; 65.28%; and 3.00% for AA, AB and BB genotypes respectively while frequencies of 0.81 and 0.19 were for A and B alleles, respectively. FH cattle populations were in equilibrium genetics. This finding concludes that polymorphism was found in three of FH populations with A allele was more common in kappa-casein locus. B allele is known having association with milk production, milk component and cheese yield. Increasing of B allele would influence on milk performance of FH cattle. Explorations of quantitative, qualitative and molecular genetics are important to improve dairy cattle performance.
