Furthermore, Fernández et al. (2004b) reported an increase in C8:0, C10:0, C12:0, and C17:0 as well as an increase in the sum of C6:0 to C20:0 as a result of betaine supplementation in lactating dairy goats. In another study, the sum of the SFA was not altered with betaine supplementation; however, C12:0, C14:0, and C15:0 increased with betaine supplementation, whereas C16:0 decreased in lactating dairy goats (Fernández et al., 2009b). Furthermore, the effects of dietary betaine
