Associations of CAST, CAPN1 and MSTN Genes Polymorphism with Slaughter Value and Beef Quality – A Review

Abstract

The slaughter value of cattle and beef quality are influenced by many factors, which can generally be divided into antemortem (breed, sex, age, housing system, diet, preslaughter handling) and postmortem (post-slaughter processing, chilling temperature, packaging). Studies of many authors have shown that meat quality traits can be also influenced by the individual genetic background of an animal. Numerous studies have been conducted worldwide to determine the functions of various genes as well as polymorphisms with potential effects on fattening and slaughter value of cattle and on beef quality. This study reviews the most important research done on the associations of polymorphisms in the calpain, calpastatin and myostatin genes with carcass traits and beef quality. Knowledge about the genes and chromosome regions associated with desired meat quality characteristics may prove very helpful when selecting pairs for mating and estimating the breeding value of offspring, mainly because it is difficult to improve meat quality traits based on conventional selection methods due to their low heritability and polygenic regulation. Furthermore, meat quality evaluation is expensive and can only be carried out after slaughter.

Genetic polymorphism of myostatin gene in Sumba Ongole (Bos indicus) cattle and its association with growth traits

“…Single-nucleotide polymorphisms are helpful as genetic markers in populations for studying their susceptibility to specific features, especially in animal production [ 41 , 46 , 51 ]. A polymorphism may have spontaneously developed with a neutral or advantageous impact if its prevalence is higher in the population [ 13 , 16 , 19 , 37 ].…”

“…It also includes an attempt to detect an association between these polymorphisms and their significance on specific species that contribute to livestock breeders’ economic growth [ 16 – 18 ]. Some other domestic farm animals have also been studied for gene polymorphism concerning muscle hypertrophy and growth traits [ 10 , 19 , 20 ]. It is especially significant in farm breeding because the introduction of current genotyping technologies has offered a new source of information for selecting farm animals [ 15 , 16 , 18 ].…”

Amplifikasi DNA Kandidat Gen Kuda Pacu Sumba

“…Adanya polimorfisme dalam gen merupakan bentuk marka molekular yang bertujuan memperlihatkan adanya munculnya kandidat gen dengan sifat-sifat tertentu yang diharapkan (Viluma, 2012;Petersen, 2014;Pereira, 2016). Hasil identifi-kasi genotip kandidat gen kuda pacu, dalam hal ini gen myostatin telah dilaporkan pada beberapa jenis hewan (Batubara, 2017;Martinez, 2016;Haruna et al, 2020;Węglarz et al, 2020). Akan tetapi, belum ada data yang melaporkan tentang kandidat gen kuda pacu sumba.…”
