Abstract

This study aimed to investigate the genetic impact of single nucleotide polymorphisms (SNPs) of the sterol regulating element binding factor 1 (SREBF1) and scavenger receptor class B member 1 (SCARB1) genes on carcass and meat characteristics, as well as fatty acid composition, in the Bali cattle. The blood and beef samples used for DNA sequencing, physical assessment, and fatty acid analysis were collected from 95 male Bali cattle. The ultrasound images were analyzed using the Image-J NIH software. A total of 4 SNPs were identified in the SREBF1 gene and 5 SNPs in the SCARB1 gene. The results showed that the 4 SNPs in the SREBF1 gene, namely g.12629T>C, g.12731T>C, g.12881A>G, and g.12986C>T, were associated with heptadecanoic acid (C17:0) and cis-11-eicosanoic acid (C20:1). The SNPs g.12731T>C of the SREBF1 gene was associated with fat content, palmitoleic acid (C16:1), stearic acid (C18:0), cis-11-eicosanoic acid (C20:1), and total fatty acids. Furthermore, 4 SNPs in the SCARB1 gene, including g.72219C>T, g.72380C>A, g.72517G>A, and g.72607C>T correlated with longissimus dorsi thickness (LDT). All SNPs in the SCARB1 gene showed significant associations with cis-10 heptadecanoic acid (C17:1) and cis 8,11,14-eicosatrienoic acid (C20:3n6). The SNP g.72400A>G of the SCARB1 gene was related to caprylic acid (C8:0), lauric acid (C12:0), arachidonic acid (C20:4n6), monounsaturated fatty acids (MUFA), and unsaturated fatty acids (UFA). These results suggested that the identified polymorphisms in the SREBF1 and SCARB1 genes could serve as valuable references for investigating similar genes in other cattle breeds, particularly concerning fatty acids.

Abstract

Pesisir cattle are native to Indonesia and originate from West Sumatra. It is known for its high environmental adaptability and can be further developed using a proteomic approach. The proteomic approach for testing the fertility of Pesisir bulls is an important factor in determining a potentially superior breed. Proteomic studies of reproduction in Pesisir bulls have not been widely conducted. This study aimed to identify and characterize functional sperm proteins in Pesisir bulls that are associated with reproductive processes. Semen samples were collected from 12 pesisir bulls aged 2–4 years and grouped into three age categories. Protein profile analysis was performed using polyacrylamide gel electrophoresis with 1D-SDS-PAGE, followed by proteolytic digestion of the proteins in the gel and protein identification using LC-MS/MS analysis. Protein functions were predicted based on analysis of biological annotations generated using UniProt, Venny, PANTHER, and STRING. Based on the evaluation of fresh semen, sperm motility in Pesisir bulls was found to increase with age. Proteomic analysis successfully identified 334 proteins in the sperm of Pesisir bulls. Among these, two proteins, ZPBP and SPACA3, were identified as involved in reproductive and fertilisation processes. Functionally, both proteins play crucial roles in acrosomal events during fertilisation. Gene Ontology analysis showed that most proteins in sperm are involved in various biological processes, including cellular activities, metabolic processes, and molecular functions related to catalytic activities. In conclusion, SPACA3 and ZPBP proteins were identified as potentially involved in reproductive processes and may serve as fertility markers in Pesisir bulls.

Abstract

The insulin-like growth factor binding-protein 7 (IGFBP7) gene is one of the potential genes related to meat quality. The objective of the current study was to evaluate polymorphism of the IGFBP7 gene (g.72351183A>C) and its association with meat quality traits in the Javanese thin-tailed (JTT) sheep. A comprehensive analysis was conducted on 88 JTT male sheep to examine their fatty acid composition, carcass characteristics, carcass retail cuts, and the physical properties of lamb meat. The polymorphism was detected using the PCR-RFLP technique. The association between the IGFBP7 gene polymorphism and the observed variables of meat quality was evaluated using one-way analysis of variance (ANOVA). The study results indicated that the IGFBP7 gene was polymorphic in JTT sheep population, with the allele distribution conforming to Hardy-Weinberg equilibrium. The AA genotype was found to be predominant. The IGFBP7 gene variants were associated (p<0.05) with erucic acid, linoleic acid, eicosapentaenoic acid, and total polyunsaturated fatty acid (PUFA). Sheep possesing the CC genotype exhibited the highest levels of linoleic acid, eicosapentaenoic acid, and total PUFA in comparison to those with AA and AC genotypes. However, the IGFBP7 gene polymorphism was not associated with carcass characteristics, carcass retail cuts, and physical properties of meat. These findings suggest that the IGFBP7 gene is a promising candidate marker for improving fatty acid composition in JTT sheep.
