Differential expression of NAT1 translational repressor during development of bovine intramuscular adipocytes.

This study was undertaken to test for differential gene expression in intramuscular adipocytes during fat deposition of feedlot steers. Angus x Hereford steers (n = 50) were fed a high-energy concentrate ration ad libitum for 20 (n = 5), 86 (n = 15), 121 (n = 15), and 146 days (n = 15) to obtain various degrees of intramuscular adipocyte development. Carcass traits were significantly different (P < 0.
