Amino Acid Analysis and Body Composition of Labeorohita Fed on Animal Protein Sources

Twelve week experiment was conducted to evaluate the amino acid availability and proximate body composition of Labeo rohita. The body meat of fish was analyzed for proximate body composition and amino acid availability. In case of analyzed amino acid high deposition of lysine, glycine, histidine and methionine were found in body meat of fish fed on reference diet while aspartic acid, alanine, glutamic acid and cystine was high in body meat of fish treated with meat meal test diet T1 and in body meat of fish raised on bone meal test diet T2 the value of valine and leucine was highest. The deposition of dry matter was highest (96.00±1.00) in body meat of fish fed reference diet followed by test diet T2 -bone meal (94.50±0.00) and (91.00±0.00) in test diet T1 meat meal. The crude fat was also high (22.65±1.10) in body meat of reference diet followed by (20.48±0.03) in T2 and (17.75±0.75) in T1. While deposition of crude protein was highest (57.7±0.18) in body of fish fed on bone meal followed by (55.23±0.55) in meat meal and (51.30±1.01) in reference diet. Crude fiber was highest (7.68±0.49) in body meat of fish treated with meat meal followed by (7.21±0.60) with bone meal and (4.24±0.67) with reference diet. The gross energy was also highest (496.51±2.62) in fish fed on meat meal followed by (462.43±0.70) in bone meal and (376.61±2.49) in body of fish treated with reference diet. While ash was highest in body meat of fish fed on bone meal (28.50±0.50) followed by (25.00±0.00) in meat meal and (23.00±1.00) in reference diet. The findings of present study revealed satisfactory growth, feed utilization and high profile of amino acids through replacement the fish meal by bone meal and meat meal in the diets of Labeo rohita.
