AB Interest in the preservation of autochthonous breeds such as the Payoya goat (dairy breed), raised using extensiveor semi-extensive grazing, has also recently increased among Spanish farmers. A study of the possibilities oftransformation to organic production needs to analyze the quality of their products, specially the suckled kids. Theobjective of this study was to evaluate the fatty acid (FA) composition of Payoya goat kids under organic andconventional grazing–based management system. Forty-eight goat kids were selected (12 males and 12 females fromeach management system). The FA profile was determined in the Longissimus thoracis muscle, kidney and pelvicfat. Few gender differences were observed in the muscle and in the fat depots. The ratios of C14:0, C18:1 trans-11-(VA), and several n-3 FA were higher in organic kid meat than in conventionally reared kid meat. Conventional kidfat depots have presented higher percentage of conjugated linoleic acid (CLA), lower CLA desaturase index, lowerpercentage of n-3 polyunsaturated fatty-acid (PUFA) and, consequently, higher n6:n3 PUFA ratio than organic kids.In conclusion, significant differences were found only in some FA percentages of muscle and adipose tissues ofsuckling kids raised in organic and conventional livestock production systems, probably due because the dams, inboth experimental farms, were raised with similar semi-extensive system based on the grazing of natural pastures.Due to this reason, conventional grazing-based management farms could easily be transformed into organic productionfacilities.
