- Abstract
Pigeon is one of the oldest domesticated animal species used by mankind in many ways. One of the most important of these its high biological value meat. Squab pigeon is still a rarely researched, especially among biotechnology research, which is evolving rapidly. Pigeon meat is once again becoming a popular and sought-after export product. Because of today’s increasing production and market competition, the future of the industry depends on precision selection programs supported by genetic and genomic tools. In this review the most important elements of gene polymorphism studies are summarized that can be associated with pigeon meat production indices based on the literature. Polymorphisms presented here were responsible for the regulation of growth properties, fat tissue, and muscle tissue. In all reviewed studies, carcass value indicators and meat quality were taken into account, which were then associated with the results of the single-point nucleotide polymorphism (SNP) assay. Polymorphisms in the MC3R and MC4R genes were correlated with growth propensity and weight gain in squab pigeons. Most of the genes studied so far are involved in the regulation of fat tissue. FABP1 gene is responsible for the function of so-called fatty acid-binding proteins, and the absence or underactivity of the KLF12 gene has resulted in increased obesity. The DGAT gene family is responsible for the synthesis of triacylglycerol, which plays an important role in the regulation of intramuscular fat deposition. MSTN gene affects the function of myostatin, the absence or mutation of which results in unusual and high levels of muscularity. Myogenesis are managed by myogenic regulatory factors (MRFs), which are responsible for skeletal muscle differentiation. A rarely studied but important factor is the MYF5 gene, which correlated with carcass muscularity and growth characteristics. Adenyl succinate lyase (ADSL) are implicated in the synthesis of inosine monophosphate (IMP). In recent decades, several studies have shown that IMP is a key factor in the taste of meat. These genes could be a potential candidate genetic marker for marker-assisted selection in squab pigeon. The review helps to form a picture of the gene polymorphisms studied in squab pigeons in the context of meat production and product quality. This provides an opportunity to identify the further research directions and to use the different results in practical selection programs.
