The microsatellite LEI0258, as a reliable marker for avian MHC typing, can be used to determine the identity of different populations and individual or breed characteristics in academic and applied studies. In this study, High Resolution Melting (HRM) analysis was used to determine MHC genotypes based on the LEI0258 microsatellite in Ross 308 broiler chickens. To this end, genotypes were first determined by conventional PCR and electrophoresis methods, as well as fragment analysis, and then the &lt;/span&gt;&lt;span style=&quot;font-size: 10.0pt; mso-bidi-font-size: 12.0pt; mso-bidi-font-family: &#039;B Lotus&#039;; mso-bidi-language: FA;&quot;&gt;findings &lt;/span&gt;&lt;span style=&quot;font-size: 10.0pt; mso-bidi-font-size: 12.0pt; mso-bidi-font-family: &#039;B Lotus&#039;;&quot;&gt;were compared and analyzed with the results of the HRM assay. From 100 samples, 5 genotypes were identified in conventional PCR and electrophoresis assays, as well as fragment analysis. These genotypes included alleles with molecular weights of 448, 385, 300, and 207 base pairs. In HRM analysis, normalized fluorescence changes versus temperature (degrees Celsius) were evaluated for five different genotypes. The results showed that the HRM method is capable of discriminating different genotypes as well as homozygous and heterozygous cases. Overall, it seems that the high-resolution melting analysis method can be applied to study the diversity of avian MHC genes. Although this technique cannot precisely identify the alleles of each chromosome, due to the co-dominant nature of MHC genes, the results are acceptable for assessing genetic composition and determining genotypes.&lt;/span&gt;</Abstract>
