The mass levels of individual fatty acyl chains were determined by neutral losses of individual fatty acid mass in MDMS-SL as previously described (15, 22). The m:n indicates the FA containing a total of m carbon atoms and n double bond. Data represent the means ± SD of at least three separate animals. *P < 0.05 and **P < 0.01 compared with those from a standard chow.
