A Systematic Review of Single Nucleotide Polymorphisms and its Association with Eggshell Thickness in Chickens
ABSTRACT Eggshell prevents microbial contamination of the egg’s internal content, and its quality determines the commercial acceptance or rejection of eggs. Broken eggs amount to about 6 to 8% of total egg production, resulting in economic loss to the egg industry. The task of animal genomics is the...

| description | ABSTRACT Eggshell prevents microbial contamination of the egg’s internal content, and its quality determines the commercial acceptance or rejection of eggs. Broken eggs amount to about 6 to 8% of total egg production, resulting in economic loss to the egg industry. The task of animal genomics is the development of accurate genetic methods to identify genes that play a role in the manifestation of commercial traits. The current report aimed to systematically review literature on single nucleotide polymorphism and its association with chicken eggshell thickness. Literature used for the current study was obtained from the Google Scholar, PubMed, ScienceDirect, and Web of Science databases using single nucleotide polymorphisms, eggshell thickness, and chickens as key words combined in various ways. From the primary search, 76 articles were obtained, and 15 qualified to be used in the study after further screening for eligibility. These 15 studies were published from 2008 to 2023, and most of them originated from China (6), Japan (2) and Nigeria (2). Ovocleidin-116 (20%), Ovocalyxin-32 (13%) and ChEST985k21(13%) were mostly investigated in different chicken breeds. In conclusion, they are considered to be the best candidate genes playing a role in the development of eggshell thickness, as there was association between genotypes and eggshell thickness. |
