A major risk to the poultry industry is antimicrobial resistance (AMR), specifically with regard to Mycoplasma gallisepticum (MG) infections. The sensitivity patterns of 100 MG isolates to biocides and antibiotics were examined in this study to clarify the interactions between antimicrobial agents and resistance mechanisms. The antimicrobial activity against MG was assessed using broth microdilution, and the results are shown as the minimum inhibitory concentration (MIC) for each strain, the MIC distribution (range), the MIC, and/or the MIC.

In our previous study, we identified a Short Interspersed Nuclear Element Retrotransposon Insertion Polymorphism (SINE-RIP) within the 3' untranslated region (3'UTR) of the Phospholipase A2 Group XVI (PLA2G16) gene, which is essential in lipid metabolism. In this study, we confirmed the presence of this 280 bp SINE insertion and examined its distribution across ten distinct pig breeds using PCR and sequencing. Subsequently, RT-PCR was employed to determine its potential for co-transcription.

Distinctive molecular approaches and tools, particularly high-throughput SNP genotyping, have been applied to determine and discover SNPs, potential genes of interest, indicators of evolutionary selection, genetic abnormalities, molecular indicators, and loci associated with quantitative traits (QTLs) in various livestock species. These methods have also been used to obtain whole-genome sequencing (WGS) data, enabling the implementation of genomic selection. Genomic selection allows for selection decisions based on genomic-estimated breeding values (GEBV).
