The Effect Of Dietary Crude Palm Oil And Alphatocopheryl
Acetate On Reproductive Performance
And Larval Quality Of Tilapia (Oreochromis sp.).
PhD thesis, Universiti Sains Malaysia.
Abstract
The present dissertation was conducted to investigate effects of the broodstock
dietary lipids and vitamin E on the reproductive performance of tilapia and the quality
of larvae hatched. Four isonitrogenous (35% protein) and isolipidic (10%) caseinbased
diets were formulated with added fish oil (FO), FO and crude palm oil (FO+CPO;
1:1), CPO or linseed oil as the lipid source in Experiment 1, and supplemented with 0
(T0), 60 (T60), 600 (T600) mg α-tocopheryal acetate, or a CPO-derived tocotrienolsrich
fraction designated to provide α-tocopherol at a level of 60 (PalmE60) mg per kg
dry diet in Experiment 2.
Disertasi in dijalankan untuk menyiasat kesan-kesan pemakanan lipid dan
vitamin E induk kepada prestasi pembiakan tilapia dan kualiti larva. Empat diet yang
isonitrogenus (35% protein) dan isolipidik (10%) berasaskan kasein dirumuskan
dengan minyak ikan (FO), FO dan minyak kelapa sawit mentah (FO+CPO; 1:1), CPO
atau minyak linseed sebagai sumber lipid dalam Eksperimen 1, dan 0 (T0), 60 (T60),
600 (T600) mg α-tokoferil asetat, atau pecahan kaya tokotrienol berasaskan CPO yang
ditetapkan untuk menyediakan α-tokoferol pada tahap 60 (PalmE60) mg sekilogram
diet kering ditambah dalam Eksperimen 2.
