Effect of Locally Manufactured Niger Seed Oil on Lipid Profile Compared to Imported Palm and Sunflower Oils on Rat Models

Table 3

The characteristic mean level of feed efficiency ratio (FER) of experimental animals (Wistar albino rats) through different weeks of the experimental period.

Feed	FER of rat in the first one week	FER of rat in the 2nd two weeks	FER of rat in the 3rd two weeks	FER of rat in the 4th two weeks	FER of rat in the final 8th weeks
Control (feed with normal pellet)	0.26 ± 0.01	0.45 ± 0.01	0.47 ± 0.006	0.48 ± 0.01	0.49 ± 0.006
Feed with 15% niger seed oil	0.16 ± 0.02	0.82 ± 0.044	0.95 ± 0.064	0.96 ± 0.067	0.94 ± 0.067
Feed with 15% sunflower oil	0.16 ± 0.035	0.23 ± 0.055	0.31 ± 0.056	0.31 ± 0.056	0.34 ± 0.069
Feed with 15% palm oil	0.97 ± 0.015	1.15 ± 0.012	1.27 ± 0.006	1.26 ± 0.012	1.24 ± 0.032

Data were expressed as means ± SD (). Values with different letters within the same column are statistically significant. In all comparisons the -value is less than 0.05 except the comparison between 15% Sunflower oil and 15% Niger seed oil on FER of Rat in the first one week of the experiment in which the .
