Abstract

| Sixty days feeding trial was conducted to study the influence of gelatinized (G) to non-gelatinized (NG) starch ratio in the diet on fatty acids profiles and lipid profile in Labeo rohita fingerlings. Two hundred and thirty four fingerlings (average weight 2.53 ± 0.04 g) were randomly distributed into six treatments with each of three replicates. Six semi purified diets either containing NG and/or G cornstarch (42.4%) were fed to respective group. Total saturated fatty acids in liver increased with the increasing level of G starch in the diet whereas reverse trend observed for monounsaturated fatty acids. Total n-3 fatty acids decreased linearly with the increasing level of G starch in the diet. Among the n-3 fatty acids linolenic acids content was more in NG starch fed group. Similarly, eicosapentaenoic acid contents gradually decreased with increasing level of G starch content. The n-6/n-3 ratio was higher in G starch fed groups compared to NG starch fed group. Total lipid content and triglyceride levels in muscle and liver increased linearly with the increasing level of G starch, whereas phospholipid and cholesterol level in muscle and liver tissue exhibited opposite trend. Conclusively, n-3 fatty acids deposition in liver of fish were higher in NG starch fed groups compared to G starch fed group. |
