THE USE OF CRUDE PALM OIL IN FINISHING PIGS' DIET: EFFECTS ON GROWTH PERFORMANCE AND NUTRIENT DIGESTIBILITY
The goal of this study was to evaluate the effect of including crude palm oil (CPO)in the diet of finishing pigs in terms of growth performance and nutrientdigestibility. In the first experiment, 40 barrows and 40 gilts(Duroc×LargeWhite×Landrace) were divided into five groups using a randomizedcomplete block design. CPO, soybean oil (SBO) and poultry fat (PF) were mixedand divided into CPOmix11 (CPO 50% + PF 50%), CPOmix13 (CPO 50% + SBO50%), CPOmix21 (CPO 75% + PF 25%) and CPOmix23 (CPO 83% +
... POmix23 (CPO 83% + PF 17%).Each group of pigs was randomly fed two diets at 50-80 and 80-100 kgBW. Group1 comprised the pigs fed diet10 (without oil inclusion) and diet20 (without oilinclusion). Group 2 comprised the pigs fed diet11 (1% CPOmix11) and diet21 (1%CPOmix21). Group 3 comprised the pigs fed diet13 (3% CPOmix13) and diet23(3% CPOmix23). Group 4 comprised the pigs fed diet10 and diet 21. Group 5comprised the pigs fed diet10 and diet23. The results showed that the pigs feddiet23 (Group 5) at 80-100 kgBW tended to have the greatest performance andlowest feed cost. In the second experiment, nutrient digestibility was examined insix barrows (initial 50 kgBW) using a 3×3 double Latin square design. Each set oftwo pigs was randomly fed diet10, diet11 or diet13. The highest (P<0.01)digestibility of dry matter, protein, crude fiber and ash and the greatest (P<0.01)digestible energy and metabolizable energy were found in diet13. The inclusion of3% CPOmix23 in the diet at80-100 kgBW might improve finishing pigperformance, and the 3% of CPOmix13 in the diet improved nutrient digestibility.
