The influences of Ɯ6/Ɯ3 dietary fatty acid ratio on growth performance and body fatty acid composition of nile tilapia (Oreochromis niloticus) [electronic resource].

Includes references.

The effect of different dietary fatty acid sources (Fish oil ( PUFA ), Soybean oil (Ɯ 6 ) , linseed oil (Ɯ 3) ) on growth performance of Nile tilapia (Oreochromis niloticus) and body fatty acids composition was investigated. Tilapia fed diet containing 4.2 ( 6/ Ɯ 3 ratio (3% soybean oil) had higher significant (P <- 0.05) differences in the final body weight, average body weight gain and specific growth rate than other treatments. Feed conversion ratio being better with diet content 4.20Ɯ6 / Ɯ3 ratio (3% soybean oil ) compared to other treatments. Body lipid content of tilapia fed diet content of 0.45 ; 1.2 and 4.6 dietary Ɯ6/Ɯ3 ratio (5% lipid level) had the highest significant (P<-0.05) values than fish fed 0.6; 1.40 and 4.20 dietary Ɯ6/Ɯ3 ratio (3% lipid level),irrespective of the dietary lipid sources. Key word: dietary Ɯ6/Ɯ3, fatty acids, Nile tilapia. Orcochromis niloticus, feed conversion.
