Association of heat-shock protein 70.1 gene with physiological and physical performance of Bali cattle.

Background And Aim: Global warming challenges cattle productivity and welfare since it affects heat stress and scarce feed. The heat-shock protein 70 () gene is essential in cytoprotection against stressors, protecting cells from dysregulated gene expression and apoptosis. This study aimed to identify significant genetic markers of the gene that can be leveraged genetically to enhance thermotolerance and production in Bali cattle further.

Open AccessLack of association between coat color abnormalities in Bali cattle () and the coding regions of the and genes.

Background And Aim: Coat color variations in cattle are known to be influenced by the melanocortin 1 receptor () and receptor tyrosine kinase () genes. The presence of coat color abnormalities, such as white spots and albinism, in Bali cattle was the focus of this study. This study aimed to identify single nucleotide polymorphisms (SNPs) in the coding region of and exons 2 and 3 of associated with coat color abnormalities in Bali cattle.

Discovery of SNPs and indel 11-bp of the myostatin gene and its association with the double-muscled phenotype in Belgian blue crossbred cattle.

Determining double muscle based on the myostatin (MSTN) gene in Belgian blue (BB), Peranakan Ongole (PO) and BB × PO crossbred cattle is very important for crossbreeding programs. This study aimed to investigate single-nucleotide polymorphisms (SNPs) and 11-bp deletions in the coding region of the MSTN gene and their relationship with the double-muscled phenotype in BB × PO crossbred cattle. A total of 86 blood samples were collected from 28 individual BB, 43 individual PO, and 15 individual BB × PO crossbred cattle.

Genetic diversity of Indonesian cattle breeds based on microsatellite markers.

Objective: This research was conducted to study the genetic diversity in several Indonesian cattle breeds using microsatellite markers to classify the Indonesian cattle breeds.

Methods: A total of 229 DNA samples from of 10 cattle breeds were used in this study. The polymerase chain reaction process was conducted using 12 labeled primers.

Multiple maternal origins of Indonesian crowing chickens revealed by mitochondrial DNA analysis.

The utilization of Indonesian crowing chickens is increasing; as such, assessing their genetic structures is important to support the conservation of their genetic resources. This study analyzes the matrilineal evolution of Indonesian crowing chickens based on the mtDNA displacement loop D-loop region to clarify their phylogenetic relationships, possible maternal origin, and possible routes of chicken dispersal. The neighbor-joining tree reveals that the majority of Indonesian crowing chickens belong to haplogroups B, D, and E, but haplogroup D harbored most of them.

Evidence of Bos javanicus x Bos indicus hybridization and major QTLs for birth weight in Indonesian Peranakan Ongole cattle.

Background: Peranakan Ongole (PO) is a major Indonesian Bos indicus breed that derives from animals imported from India in the late 19(th) century. Early imports were followed by hybridization with the Bos javanicus subspecies of cattle. Here, we used genomic data to partition the ancestry components of PO cattle and map loci implicated in birth weight.
