Carbohydrate utilization and its effect on performance, digestiblity and metabolic parameters of Nile tilapia [Oreochromis niloticus]

Two experiments were carried out with Nile tilapia [O. niloticus] fingerlings. The first experiment was designed to evaluate the influence of seven levels of dietary D-glucose [0, 4, 8, 12, 16, 20 and 24%] on the performance, digestibility and metabolic parameter of O. niloticus fingerlings of 19.99 g +/- 0.21. The second experiment included four-carbohydrate source glucose, maltose, sucrose and starch for O. niloticus fingerlings of 20.08 g +/- 0.59 to study its effect on the performance, digestibility and metabolic parameter. Each diet was fed to triplicate groups of O. niloticus for eight weeks. The study concluded that D-glucose could be added in diets up to 16% without negative effects on the performance and digestibility and starch considered a suitable source of carbohydrate for O. niloticus

Utilization of amino acids in nile tilapia [oreochromis niloticus] fry. 3- Utilization of non-essential amino acids as energy source

An experiment was designed to find out the effect of the replacement of essential amino acids by non-essential amino acids as energy source at seven ratios [45%: 55% as a control, 50%: 50%, 40%: 60%, 35%: 65%, 30%: 70%, 25%: 75% and 20%: 80%, essential amino acid: non-essential amino acid,] respectively. The higher significant [P
