Abstract

Kajian ini dijalankan untuk menguji kesan penggantian sepenuhnya dan penggantian separa minyak ikan (FO) dengan minyak kelapa sawit mentah (CPO) dan minyak kelapa (CNO) ke atas prestasi pertumbuhan, penggunaan pemakanan, kandungan proksimat dan kandungan asid lemak di dalam otot dan hati ikan keli Africa (Clarias gariepinus). Ini diikuti dengan kajian kesan penyimpanan beku ke atas kualiti otot ikan setelah diberi pemakanan uji selama 12 minggu. Lima diet praktikal berisonitrogen (35% protein kasar) dan isotenaga (19.73 kJ g-1) dirumuskan untuk mengandungi 8% minyak ikan (FO, Diet 1), minyak sawit mentah (CPO, Diet 2), minyak kelapa (CNO, Diet 3), 1:1 minyak ikan ke minyak sawit mentah (FO/CPO, Diet 4) dan 1:1 minyak ikan ke minyak kelapa (FO/CNO, Diet 5). Setiap diet diberi kepada dua replikat kumpulan ikan yang mengandungi 90 ekor ikan, pada berat awal 6±0.05 gm yang ditempatkan dalam tangki simen sehingga ikan membesar sehingga saiz pasaran sebanyak  180 gm. This study was carried out to investigate the effects of total and partial replacement of fish oil (FO) with crude palm oil (CPO) and coconut oil (CNO) on growth performance, feed utilization, proximate composition and fatty acid composition of muscles and liver of African catfish (Clarias gariepinus). This was followed by an investigation on the effect of frozen storage on the muscle quality of fish raised on the respective test diets after 12 weeks. Five isonitrogenous (35% crude protein) and isoenergetic (19.73 kJ g-1) practical diets were formulated to contain 8% of fish oil (FO, Diet 1), crude palm oil (CPO, Diet 2), coconut oil (CNO, Diet 3), 1:1 fish oil to crude palm oil (FO/CPO, Diet 4) and 1:1 fish oil to coconut oil (FO/CNO, Diet 5). Each diet was given to duplicate groups of 90 fish with an initial weight of 6 ±0.05 gm in cement tanks until they reached the marketable size of  180 gm.
