Figure 3. Changes in specific fatty acids and classes of
fatty acids during postweaning growth of steer calves.
A) Oleic (18:1) and linoleic acid (18:2) increased with
age, whereas linolenic acid (18:3) declined with age (all
P < .05). B) Total unsaturated fatty acids (UFA),
monounsaturated fatty acids (MUFA), and polyunsaturated
fatty acids (PUFA) increased (P < .05) with
postweaning age. Conversely, total saturated fatty acids
(SFA) declined 10 percentage units (P < .001) during this
period. Data are pooled across breed-type. Pooled mean
square error bars (SEM) are affixed to each data set,
although they are obscured by the symbols for 18:3.
