An experiment was conducted to evaluate the use of different crystalline methionine sources to optimize amino acid profiles and its effect on growth performance and feed utilization in feeds of all male tilapia O. niloticus.Seven treatment were applied, one basal diet as negative control which contain 3.9g kg -1 Methionine (MET) and diets (2-6) were supplemented with two levels of MET dietary (0.15–0.30%) of DLMET, novel MET1and MET2 at a constant dietary cysteine level of 3.9 g kg -1 , respectively. The tested diets formulated to contain 28% crude protein and 18.7 MJ GE, applied in 28 fiberglass tanks, 25 Nile tilapia fingerlings (13.5 ± 0.40g). Growth performance and feed efficiency were improved significantly for tilapia fed on diets supplemented by different MET products compared to non supplemented diet (control). The present study clearly shows that optimizing the amino acid profile by inclusion of a single crystalline amino acid (crystalline MET) does not give the same protein utilization as that of a diet in which the amino acids are mainly protein bound. Diet containing MET1 improved protein utilization than DLMET or MET2.
