The objective of this research was to evaluate the effect increasing levels associated glutamine and glutamic acid on growth performance intestinal development Nile tilapia, Oreochromis niloticus, fingerlings. Five isoproteic (~344.70 g kg−1 crude protein) isocaloric diets (~3,925 kcal gross energy) were developed containing 0, 5, 10, 15, or 20 in extruded diets. Fish (n = 2,000, mean body weig...

The present study aimed to elucidate the impacts of dietary vegetable oil blends as alternative to fish oil on serum biochemical and haematological parameters in Heterobranchus longifilis fingerlings. Fish (4.65 ± 0.23g) were fed diets containing fish oil (FO), palm oil (PO), soybean oil (SO), blend of PO and SO (POSO) over a 12-week period. The experiment was carried out in 62-l circular tanks...
