Abstract
Fatty acid composition of adipose tissue associated with meat is an important factor for the beef industry because of its implications for human health, processing, meat quality, and palatability. Individual fatty acid composition is a trait under genetic control, so improvement via selective breeding of cattle is possible. The objective of this study was to investigate the genetic architecture of fatty acid composition and identify genes associated with this trait in 3 breed types: Bos indicus (Brahman), Bos taurus (4 breeds), and tropically adapted composites (2 breeds). Using high-density data, regions on chromosomes 1, 9, 14, 16, 19, 23, 26, 29, and X were associated with fat composition and quantity traits. Known candidate genes, such as fatty acid synthase (FASN; chromosome 19) and stearoyl-CoA desaturase (SCD; chromosome 26), were confirmed in our results. Other candidate genes and regions represent novel association results, requiring further validation.
