Abstract
Abstract The primary aim of this study was to estimate the relationship between ATP citrate lyase (ACLY) gene polymorphism (c.*523 T>C) and fattening and pork quality traits. Investigations were carried out on 526 pigs represented by three breeds: Polish Landrace (n=269), Polish Large White (n=189) and Puławska (n=68). ACLY genotypes were determined by PCR–RFLP method. It was demonstrated that the analyzed polymorphism had significant influence (P<0.05 and P≤0.01) on several economically important traits in pigs, e.g. average daily gain, average backfat thickness, lean meat percentage. The results obtained allow for application of c.*523 T>C polymorphism in breeding programs to improve the pig population in terms of fattening and slaughter traits. However, this breeding program may have a slight negative effect on meat texture parameters.
Highlights
Garding its safety and influence on human health
The present study shows similar frequency of ATP citrate lyase (ACLY) (c.*523 T>C) genotypes and alleles between the breeds investigated (Table 1)
The high number of heterozygotes in our research may be due to the fact that the samples were randomly selected
Summary
Garding its safety and influence on human health. The overall selection goal in modern breeding programs is directed to improving qualitative and quantitative features that are economically important in pork production. The fatty acid composition (FAC) in the pig carcass and meat is an important factor in determining pork quality (Davoli et al, 2019). The chromosome (SSC12) is relevant to the genetics of fatty acids (FA) composition because of genes involved in the biosynthesis of FA (Clop et al, 2003; Muñoz et al, 2007). UTRs jointly with other factors interacting with RNA may be responsible for stability, transport, and sub-cellular localization of mRNA as well as the efficiency of translation, which affects the total amount of synthesized protein (Matoulkova et al, 2012) Polymorphism located in this area can influence all the mechanisms mentioned above and in turn may affect phenotypic traits in animals, especially with high economic importance. The aim of this study was to estimate associations between ACLY polymorphism c.*523 T>C and fattening, slaughter and meat quality traits in three Polish pig breeds
