A total of thirty sows(Landrace×Yorkshire) were used to determine the effects of dietary coconut fat powder supplementation on performance, nutrients digestibility, blood and milk characteristics. A feeding trial was conducted for 21 days from parturition to weaning. Experimental diets were supplied for 1 week before the parturition day and throughout the experimental period. Dietary treatments included: 1) CON(basal diet), 2) CFP(basal diet added 0.5% coconut fat powder) and 3) CFH(basal diet added 0.5% coconut fat power containing husk). An average daily feed intake was significantly improved in CFP and CFH treatments compared with CON treatment(P<0.05). A backfat loss was significantly lower in CFP and CFH treatments than CON treatment(P<0.05). Compared with CON treatment, final body weight, weight gain and average daily gain in piglet were significantly increased in CFP and CFH treatments(P<0.05). Red blood cell was significantly increased in CFH treatment compared with others(P<0.05). White blood cell at the final period and lymphocyte at the final period and differences were significantly increased in sows fed coconut fat powder diet(P<0.05). At the final period, a milk fat concentration was significantly improved in CFP and CFH treatments compared with CON treatment(P<0.05). A milk protein concentration was significantly higher in CFP treatment than CFH treatment at the initial period(P<0.05) and was significantly lower in CFP and CFH treatments than CON treatment at the final period(P<0.05). And a milk lactose concentration at the initial period was significantly increased in CFH treatment compared with CON and CFP treatments(P<0.05). On diarrhea rate in piglet, three piglet occurred in CON treatment. In conclusion, dietary fat source from coconut supplementation improved feed intake, backfat loss, RBC, WBC and lymphocyte in sow and weight gain in piglet.
