Figure 2. Bar chart combining the individual fatty acid composition of abdominal fat (upward bars), subcutaneous fat (downward
bars) and NEFA (▬) in dairy cows suffering from a left displacement of the abomasum. The cited literature is indicated for dairy
(open symbols: Rukkwamsuk et al., 2000; Sato and Inoue, 2006; Douglas et al., 2007; Zachut et al., 2010a) or beef (black symbols:
Eichhorn et al., 1986; Beaulieu et al., 2002; Oka et al., 2002; Siebert et al., 2003) cattle. The abdominal depot is presented as
mesenterical (square symbol) or perirenal (round symbol) fat. To better allow comparison with both adipose tissues, blood plasma
NEFA proportions as measured in the current study were presented both in the upward and downward bars.
