The biological experiment was carried out by using, five hundred and twenty five day old straight-run Japanese quail chicks up to 5 weeks of age for post hatch growth performance studies. Individual body weight and total feed consumption in each replicate group were recorded at weekly intervals to calculate the weight gain and feed efficiency. The mean body weight gain at the end of fifth week ranged between 204.53 g and 223.78 g and birds fed basal diet with 4 per cent fish oil (T4) had significantly higher body weight gain (223.78 g) as compared to Japanese quail fed basal diet alone (T1) (210.66 g). However, the Japanese quail fed 4 per cent linseed oil (204.53 g) had the lowest body weight gain at fifth week of age between the treatment groups. Japanese quail grouped under 4 per cent fish oil had better feed efficiency (2.77) when compared to control group alone. Meanwhile, the birds grouped under 4 per cent linseed oil recorded poor feed efficiency (3.14) between the treatment groups. It is concluded that inclusion of n-3 PUFA rich fish oil and linseed oil sources at graded levels independently and simultaneously in Japanese quail feed revealed that birds fed diets enriched with fish oil at four and two per cent levels had significant (P<0.01) effect on body weight gain and feed efficiency with non-significant variation observed in cumulative feed consumption.EnglishVeterinary ScienceArticle
