Abstract

The apparent digestibility (AD) of dry matter (DM), organic matter (OM), crude protein (CP) and essential amino acids (EAA) in five selected feedstuffs was evaluated in hybrid catfish and Nile tilapia. The AD of DM, OM and CP in cassava leaf meal (CLM) was lower (P < 0.05) than in groundnut meal (GNM), soybean meal (SBM), sesame husk meal (SSH) and shrimp head meal (SHM). The AD of DM, OM and CP among GNM, SBM, SSH and SHM was not different (P > 0.05). The AD of most EAA was higher in SSH (P < 0.05) than in CLM, GNM, SBM and SHM. The AD of most EAA among CLM, GNM, SBM and SHM was not different (P > 0.05). The AD of DM and OM in CLM was higher (P < 0.05) in hybrid catfish than in Nile tilapia, while there was no difference in the AD of CP in CLM between fish species. The AD of DM, OM, CP and EAA among GNM, SBM, SSH and SHM did not differ between hybrid catfish and Nile tilapia. In conclusion, there were only small differences in the nutritional properties between the selected feedstuffs in both fish species. Most EAA in the selected feedstuffs were equally well utilized by hybrid catfish and Nile tilapia.
