Abstract

Diacylglycerol acyltransferase 1 (DGAT1) is a potential candidate gene for improving Indonesian lamb’s quality and nutrient value.  The study aimed to identify the diversity of the DGAT1 gene with SNP g.8539 CT and its relation to Indonesian lamb's flavor and odor, cholesterol, and mineral.  Total of 254 ten to twelve months old sheep consisted of 20 Javanese fat-tail sheep (JFTS), 107 Javanese thin-tail sheep (JTTS), 10 Garut composite sheep (GCS), 10 Compass agrinak sheep (CAS), 10 Barbados cross sheep (BCS), 20 Garut sheep (GS), 27 Jonggol sheep (JS), and 50 Jambi local sheep (JLS).  One hundred sheep were used to analyze the association of the DGAT1 gene with flavor and odor content, cholesterol, and mineral.  The diversity of DGAT1|AluI was analyzed with the PCR-RFLP method.  The association of the DGAT1 gene with the nutritional value of meat was analyzed using the GLM (General Linear Model) method.  The results showed that the DGAT gene was polymorphic in JTTS, GS, and JFTS and monomorphic in CAS, BCS, JLS, and GCS.  CC and CT genotypes were found in JTTS, GS, and JFTS.  SNP g.8539 CT of DGAT1 gene had a significant association (P0.05) with flavor and odor, 4-Ethyloctanoic Acid (EOA).  However, the DGAT1 gene had no significant association (P0.05) with cholesterol and mineral.  The DGAT1 gene might be marker-assisted selection for improving lamb flavor and odor in Indonesian sheep.

Abstract

The Complement Factor H Related 5 (CFHR5) gene is speculated to have an important role in regulating fatty acid composition in sheep. The aim of this study was to investigate the polymorphism of the CFHR5 gene and its association with fatty acid composition and cholesterol of sheep in Indonesia. A total of 172 rams from 83 priangan sheep (PS), 20 sapudi sheep (SS), 19 Garut sheep (GS), 20 jonggol sheep (JS), 10 Garut composite sheep (GCS), 10 compass agrinac sheep (CAS), and 10 Barbados cross sheep (BCS) were used for this study. Identification of CFHR5 gene polymorphism were performed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) using AciI restriction enzyme. The results showed that the CFHR5 gene in all sheep populations were polymorphic producing three genotypes, e.g. CC, CT and TT, respectively. The polymorphism had a significant effect (p<0.05) on fatty acid composition (miristoleic [C14:1], ginkgolic [C17:1], tridecanoic [C13:0], and heptadecanoic [C17:0] acids) and cholesterol. The breed and polymorphism had a significant effect (p<0.05) on fatty acid composition (JS with tridecanoic acid [C13:0] and BCS with miristoleic acid [C14:1]). The CC genotype is the preferred genotype and as it exhibits reduced levels of saturated fatty acids and cholesterol. The BCS sheep is the preferred genotype and as it exhibits high PUFA/SFA ratio. The CFHR5 gene (SNP c.1011C>T) has the potential to be used as a genetic marker for the selection of low saturated fatty acid composition and cholesterol in sheep

Abstract

The Kerinci duck (Anas platyrhynchos), hailing from Jambi Province, represents one of the local duck breeds of Indonesia. This study aimed to ascertain the matrilineal origin of Kerinci ducks through analysis of the mitochondrial NADH Dehydrogenase subunit 2 (MT-ND2) gene. In this pursuit, forward sequences of the MT-ND2 gene (490 bp) were extracted from unsexed Kerinci ducks, totalling forty-eight (48) sequences, procured from blood samples. The findings demonstrated the identification of fifteen (15) distinct haplotypes within the MT-ND2 gene, with corresponding haplotype diversity (Hd) and nucleotide diversity (pi) values of 0.74 and 0.003, respectively. The resulting phylogenetic tree unveiled that Kerinci ducks exhibit two matrilineal origins: an Asian and an independent Kerinci lineage. Moreover, most Kerinci ducks were categorised within the H4 group (24 birds) of the Asian lineage. Nevertheless, this study also revealed the existence of an independent Kerinci lineage comprising eight (8) duck haplotypes. In conclusion, the analysis of the MT-ND2 gene underscored the genetic introgression of A. zonorhyncha and A. poecilorhyncha in Kerinci ducks.

Abstract

HSD17β13 (17beta 13-Hydroxysteroid dehydrogenases) are important enzymes in steroid metabolism. This study investigated the polymorphisms and expression of the HSD17β13 gene in lamb quality traits in Indonesian sheep. A total of 200 of rams of seven breeds administered in the study were Javanese fat-tailed (JFT), Javanese thin-tailed (JTT), Garut sheep (GS), Jonggol sheep (JS), Garut composite sheep (GCS), Compass agrinac sheep (CAS), Barbados cross sheep (BCS) aged 10-12 months and weighed 20-30 kg. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) and MspI enzyme restriction were performed to identify the polymorphism of the HSD17β13 gene. The lamb quality traits were measured for physical quality, flavor, odor, and fatty acid composition. The results showed that the HSD17β13 gene was polymorphic and had three genotypes i.e., CC, CT, and TT. The highest genotype frequency was the CC when compared to the other genotypes. The allele frequency of HSD17β13 gene was not in Hardy Weinberg Equilibrium. The polymorphism of HSD17β13 gene was significantly (P<0.05) associated with the fatty acid composition and Saturated Fatty Acid (SFA), i.e., tridecanoic acid (C13:0), arachidic acid (C20:0), henecosanoic acid (C21:0), and tricosanoic acid (C23:0). The polymorphism was also significantly associated with the Monounsaturated Fatty Acid (MUFA) i.e. ginkgoleic acid (C17:1) and nervonoic acid (C24:1), and Polyunsaturated Fatty Acid (PUFA) i.e. eicosedienoic acid (C20:2). The level of expression of the HSD17β13 gene based on quantitative real time-PCR analysis results was not significantly different (P>0.05) among genotypes for lamb quality traits. It can be concluded that the polymorphism of HSD17β13 gene was associated with the fatty acid composition of lamb in Indonesian sheep.

Abstract

The PPM1K (Protein Phosphatase, Mg2+/Mn2+ Dependent 1K) gene is assumed to associate with retail meat cuts. This study aims to determine the association of the PPM1K gene polymorphisms with retail meat cuts among various breeds of Indonesian sheep. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) approach was used to determine the polymorphisms of the PPM1K gene in 130 Indonesian rams aged 10-12 months with body weights ranging from 20-25 kg. The association study between PPM1K and retail meat cuts was analyzed using General Linear Model (GLM). The research showed that the PPM1K gene was polymorphic, with three genotypes: AA (458 bp), GG (259 bp and 199 bp), and AG (458 bp, 259 bp, and 199 bp). The PPM1K gene polymorphisms were significantly (P<0.05) associated with breast cut, which is the breast muscle and bone. The GG genotype of the PPM1K gene had a higher value on breast lamb. This result implies that the PPM1K gene could be a potential candidate for marker-assisted selection for improving the lamb quality of Indonesian sheep.

Abstract

Flavor and odor are important factors for consumers to consider the quality of lamb meat. The AHSG Alpha2-Heremans- Schmid Glycoprotein gene is associated with a fatty acid content and is indicated as a gene controlling flavor and odor compounds. The research aims to identify the AHSG gene polymorphism and its association with flavor and odor compounds in Indonesian lamb meat. The sample used in this study was 105 ram samples consisting of 10 Javanese Fat-Tailed Sheep (JFTS), 80 Javanese Thin-Tailed Sheep (JTTS), and 15 Jonggol sheep (JS). The AHSG gene polymorphism was validated using the PCR-RFLP technique with the EagI enzyme EagI. The association of the AHSG gene SNP (g.198655287 G>A) with odor and flavor was analyzed using the T-tests. The AHSG gene polymorphism in Indonesian lamb was polymorphic with three genotypes, i.e., GG, GA, and AA, and in the Hardy-Weinberg equilibrium. The AHSG significance was associated (P<0.05) with skatole compounds (MOA, EOA, MNA, and MI). The AA genotype is recommended for a candidate marker of flavors and odors because it associated with low compound values. The AHSG gene, specifically the SNP g.198655287 G>A, can potentially serve as a genetic marker for lamb meat production by reducing flavor and odor.
