• Twenty-four crossbred (Landrace × Yorkshire) finishing pigs with an average live weight of 56.8 ± 1.8 kg (mean ± S.E.) comprising equal numbers of barrows and gilts were used for 48 days. Couples of both a barrow and gilt were randomly allocated to a total of 12 pens. The trial was designed as a 2 × 2 factorial experiment with dietary treatments which consisted of diets containing 5.0% catfish (<I>Pangasius hypophthalmus</I>) or coconut (<I>Cocos nucifera</I>) oil (F5 or C5, respectively), with or without 5.8% water spinach (<I>Ipomoea aquatica</I>) (W0 or W6, respectively). No significant effects or interaction by the treatments were found on the daily weight gain, feed conversion ratio (FCR) and cost conversion ratio expressed as feed cost multiplied by FCR (p > 0.1). An interaction on backfat thickness was found (p < 0.05); it tended to be lower (p < 0.1) for diets supplemented with catfish oil than for diets with coconut oil, when water spinach was not added; and it was reduced (p < 0.001) by the water spinach supplementation, when coconut oil was also supplemented. As for the carcass traits, the types of oils had an effect on the iodine value of backfat; the value was significantly higher in F5 diets than that in C5 diets (p < 0.001). Significant differences were found in the pH values, the DM (dry matter) content of fresh loin muscle and the iodine value of backfat between W0 and W6 diets (p < 0.01). Overall, a diet with 5.8% water spinach and that with 5.0% catfish oil with no water spinach would be recommended to improve the farmers′ common pig diet in the region.
