Table 5.
Expression of mRNA (relative fold change) of longissimus muscle (LM) genes in the feedlot, and carcass traits of steers supplemented with Ca soaps of soybean oil (CSSO; n = 16) or prilled saturated fat (CON+; n = 16) from 2 to 4 months of age. Values reported are least square means ± standard error. Adapted from Schubach et al. [62].
