The presented values are the mean ± SD of triplicates (n=3).
The significant difference among treatments was indicated by different superscripts in each column (p < 0.05).
The determined lipid levels in the experimental diets were 79, 119, 160, 193, and 228 g/kg for the L80, L120, L160, L200, and L240, respectively.
Final body weight (g).
Specific growth rate (%) = [(Loge final body weight – Loge initial body weight) / days] × 100.
Feed conversion ratio = dry feed fed / wet weight gain.
Protein efficiency ratio = wet weight gain / total protein given.
Lipid efficiency ratio = wet weight gain / total lipid given.
Lipid retention = [(final body weight × final body lipid – initial body weight × initial body lipid) / total lipid given] × 100.
