Effect of bacterial single cell protein in rainbow trout (Oncorhynchus mykiss) diet on body composition and digestive enzymes activity
In this study, body composition and digestive enzymes activity was assessed in rainbow trout fry (weight 2.51 ± 0.55 g) fed by bacterial single cell (BSC) as a dietary protein source replaced with fish meal as completely randomized design with triplicate for 6 weeks. Experimental diets were prepared in 5 treatments as isonitrogenous with different levels of fish meal and BSC (100% fish meal (A)...
متن کاملStudies on the “cobalt” Variant of Rainbow Trout
The “cobalt” variant of rainbow trout Oncorhynchus mykis lacks most of the pars intermedia of the pituitary in which melanocyte-stimulating hormone (MSH) cells are distributed. An excessive accumulation of fat in the abdominal cavity is also observed in variant. In this study, the role of MSH on lipid metabolism of the trout and the possible relation to fat accumulation in the cobalt variant we...
متن کاملThe effect of Earth worm ( Eisenia fetida) difference levels on growth performance and body composition and Nutrition and Digestive Enzymes of Rainbow trout (Oncorhynchus mykiss)
This experiment was designed to investigate the use of live Eisenia fetida as a nutritional supplement on growth performance and carcass composition The purpose of this study was to evaluate the nutritional efficiency and changes in digestive enzymes of rainbow trout (Oncorhynchus mykiss). Fish were placed with average weight 58 g in a completely randomized design in 4 treatments and each with ...
متن کاملThe effect lactic acid supplementation in diet of rainbow trout on growth parameters, activity of digestive enzymes and intestinal bacterial flora
The aim of this study was to investigate the effect of adding lactic acid to the diet of rainbow trout on growth indices, activity of digestive enzymes and microbial flora of the fish gastrointestinal tract. For this purpose, 4 diets containing 0, 5, 10 and 20 g of lactic acid per kg of diet were made and each diet was offered to fish in three replications for 8 weeks. The results showed that t...
متن کاملReduced lipid intake leads to changes in digestive enzymes in the intestine but has minor effects on key enzymes of hepatic intermediary metabolism in rainbow trout ( Oncorhynchus mykiss).
For sustainable aquaculture, the removal of marine resource ingredients in fish diets is an important objective. While most studies focus on the replacement of fish oil by vegetable oil, little is known on the nutritional effects of presence (which corresponds to the control diet) or absence of dietary fish oil. We studied fatty acid composition of brush-border membranes and digestive enzyme ac...
