THE USE OF CRUDE PALM OIL IN FINISHING PIGS’ DIET: EFFECTS ON GROWTH PERFORMANCE AND NUTRIENT DIGESTIBILITY

Abstract

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 nutrient
digestibility. In the first experiment, 40 barrows and 40 gilts
(Duroc×LargeWhite×Landrace) were divided into five groups using a randomized
complete block design. CPO, soybean oil (SBO) and poultry fat (PF) were mixed
and divided into CPOmix11 (CPO 50% + PF 50%), CPOmix13 (CPO 50% + SBO
50%), CPOmix21 (CPO 75% + PF 25%) and CPOmix23 (CPO 83% + PF 17%).
Each group of pigs was randomly fed two diets at 50-80 and 80-100 kgBW. Group
1 comprised the pigs fed diet10 (without oil inclusion) and diet20 (without oil
inclusion). 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 5
comprised the pigs fed diet10 and diet23. The results showed that the pigs fed
diet23 (Group 5) at 80-100 kgBW tended to have the greatest performance and
lowest feed cost. In the second experiment, nutrient digestibility was examined in
six barrows (initial 50 kgBW) using a 3×3 double Latin square design. Each set of
two 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 of
3% CPOmix23 in the diet at80-100 kgBW might improve finishing pig
performance, and the 3% of CPOmix13 in the diet improved nutrient digestibility.
