^aDairy cows were divided into two nutritional regiment groups from −21 to 60 days PP; 1) Control group (CTL)—a standard Israeli diet, 2) FLX—a standard diet supplemented with flaxseed oil containing n-3. ^b2-Arachidonoylglycerol; ^cArachidonic acid; ^dAnandamide; ^eN-palmitoylethanolamine; ^f N-Oleoylethanolamine. Liver samples were taken from 5 cows per treatment at 10.2 ± 1.0 DIM while AT samples were obtained from 6 cows from each treatment at 7.7 ± 1.9 DIM
