In Vietnam, SMEDI syndrome in sows caused by PPV is nationwide and has been of concern since the early 1990s. Previous studies have investigated the prevalence of PPVs using serological testing and PCR methods. The objective of this study is to analyze the genotypic prevalence of PPVs and molecular characterization of VP gene of PPV2 from slaughtered pigs in Central Vietnam.

This study aimed to estimate the allelic and genotypic frequencies of single nucleotide polymorphisms (SNPs) of MC4R (melanocortin-4- receptor gene) and PIT1 (pituitary specific transcription factor-1) genes, and their additive dominance genetic effects on production and carcass traits in Duroc pigs.

Genomic selection and genomic wide association studies are widely used methods that aim to exploit the linkage disequilibrium (LD) between markers and quantitative trait loci (QTL). Securing a sufficiently large set of genotypes and phenotypes can be a limiting factor that may be overcome by combining data from multiple breeds or using crossbred information.

The number of animals born dead, which includes the number of mummified (NM) and stillborn (NS) animals, is the most important trait to directly quantify the reproductive loss in domestic pigs. In this study, 282 Landrace sows and 250 Large White sows were genotyped by sequencing (GBS).

Two individuals with a first-degree relationship share about 50 percent of their alleles. Parent–offspring relationships cannot be homozygous for alternative alleles (genetic exclusion). Methods: Applying the concept of genetic exclusion to HD arrays typed in animals for experimental purposes or genomic selection allows estimation of the rate of rejection of first-degree relationships as the rate at which two individuals typed for a large number of Single Nucleotide Polymorphisms (SNPs) do not share at least one allele.

Porcine circovirus type 2 (PCV2) is the pathogen of porcine circovirus associated diseases (PCVAD) and one of the main pathogens in the global pig industry, which has brought huge economic losses to the pig industry. In recent years, there has been limited research on the prevalence of PCV2 in Henan Province. This study investigated the genotype and evolution of PCV2 in this area.

Salmonella enterica serovars are a major cause of foodborne illness and have a substantial impact on global human health. In Canada, Salmonella is commonly found on swine farms and the increasing concern about drug use and antimicrobial resistance associated with Salmonella has promoted research into alternative control methods, including selecting for pig genotypes associated with resistance to Salmonella.

Porcine circovirus type 2 (PCV2) is an immunosuppressive pathogen with high prevalence rate in pig farms. It has caused serious economic losses to the global pig industry. Due to the rapid mutation of PCV2 strain and co-infection of different genotypes, vaccination could not eradicate the infection of PCV2.

Between 2018 and 2020, 989 clinical specimens from pigs showing clinical signs of a variety of swine diseases in 27 provinces in China were sampled and submitted for further testing. Nested PCR targeting the 16S rRNA gene of Mycoplasma hyopneumoniae and subsequent sequencing were used to analyse these specimens. Mycoplasma hyopneumoniae-positive samples were assayed by multilocus sequence typing (MLST).

The aim of the thesis research: Determine the polymorphisms of MC4R, PIT1, GH, LEP, PIK3C3 genes and their association with the traits of growth performance, backfat thickness, and reproductive performance in Duroc pigs; determine the polymorphism of ADRB3, ACSL4, FABP3, PLIN2 genes and the association with the intramuscular fatin Duroc pigs; select the Duroc pig line in the direction of growth performance using the support from genotype information.

Palatoschisis or cleft palate is a known anomaly in pigs resulting in their death. However, little is known about its aetiology. A detailed description of the phenotype was derived from necropsy and by computed tomography revealing that all 20 cases also exhibited hypodontia and renal cysts.

The key-ancestor approach has been frequently applied to prioritize individuals for whole-genome sequencing based on their marginal genetic contribution to current populations. Using this approach, we selected 70 key ancestors from two lines of the Swiss Large White breed that have been selected divergently for fertility and fattening traits and sequenced their genomes with short paired-end reads.

Rapid screening for phenotype-genotype associations by linear transformations of genomic evaluations
Currently, association studies are analysed using statistical mixed models, with marker effects estimated by a linear transformation of genomic breeding values. The variances of marker effects are needed when performing the tests of association.

The Ryanodine Receptor-1 gene (RYR-1) is located in the 6p11 → q21 region on the No. 6 chromosome of pigs. RYR-1 is being investigated in several studies as a potentially important gene that is an indicator of pork quality. In this article, PCR-RFLP was used to analyze RYR-1 polymorphism in 19 Mong Cai pigs, 2 Yorkshire pigs and their 64 F1 generation pigs.

The birth of livestock genomics 15 years ago was inspired by the human genome initiative and the potential for capturing both its technologies and massive comparative data sets for application to livestock species, most of which are mammals. We are currently reaping the benefits of these efforts, with sequencing projects completed or ongoing in chickens, cattle, pigs, and horses and valuable mapping resources developed for others such as sheep and turkeys.
