Abstract

This experimental study aims to compare feed intake, digestibility and nitrogen retention of pigs fed with four diets. Eight castrated male pigs (Yorkshire x Local breed) of average live weight of 15 kg were given four diets in a double 4*4 Latin square arrangement. The experiment included four treatments, including T1: Concentrate feed 15% + Water spinach 50% + Rice bran 35%; T2: Concentrate feed 30% + Water spinach 35% + Rice bran 35%; T3: Concentrate feed 45% + Water spinach 20% + Rice bran 35%; and T4: Concentrate feed 60% + Water spinach 5% + Rice bran 35%. The results showed that the total intakes of dry matter (DM) and crude protein (CP) in T4 were (1.044g/day) and (182.5g/day), respectively, which were significantly higher than the other three treatments (p<0.01). The digestibility of T4 was significantly higher than the other three treatments (p<0.01) as well. The nitrogen retention of T4 (10.84g/day) was also significantly higher than T1 (p<0.01). However, there was non-significant difference as compared to T2 and T3 (p>0.05). Overall, the mixture of concentrate feed 60%, water spinach 5%, and rice bran 35% made the pigs get high feed intake and high digestibility, as well as better Nitrogen absorption in their bodies.
