3.1. Fatty acid composition of milk
Mean, SD, minimal and maximal values of the FA identified by
GC in the milk samples are presented in Table 1. The milk FA contents
showed variability similar to that reported by Alonso,
Fontecha, Lozada, Fraga, and Juárez (1999). These authors studiedthe range of variation of milk FA from Murciano-Granadina goats in
the Murcia region (Spain), collected from five herds during 7 consecutive
months. However, the range of variation of the FA contents
observed in the present work was narrower than the
reported by Andueza et al. (2013), particularly in MUFA and n-3
FA, but those authors included in their study samples from trials
where plant and marine oils were added to goat diets.
As expected, the selection of a number of random samples from
each milk control allowed getting similar variability of milk FA in
both R and T calibration sets (Table 1).
