2.1. Milk samples
A total of 805 individual milk samples of Murciano Granadina
goats from four commercial farms were used. The herds were
under an official milk recording scheme and the diets supplied
were based on alfalfa hay and commercial concentrates (Zidi
et al., 2010). Milk samples were collected from a series of individual
controls along three different lactation (Nov’07–Jun’08 (11 controls);
Nov’08–Jun’09 (10 controls) and Feb’10–Jul’10 (7 controls),
in order to obtain maximum seasonal variation. Milk samples were
collected in the farm and kept at 4 C for transportation. One subsample
was used for the reference analysis of FAs, by gas chromatography
(GC), and the other sub-sample was used for NIR
analyses. Once in the laboratory, samples were added Wide
