Production Performance and Serum Biochemical Indices as Influenced by Lysine and Methionine Supplementation to Low Protein Diet in Vanaraja Laying Hens

An experiment was conducted to evaluate the effect lysine and methionine supplementation low protein diet on production performance serum biochemical parameters in Vanaraja laying hens. One hundred twenty (n=120), 30-weeks old hens were randomly distributed into four dietary treatments with three replicates each group having 10 birds replicate. Four diets formulated 2600 kcal/kg of metabolizable energy (ME) 13% crude (CP). The were: T1- contains 0.65% 0.28% methionine; T2- 0.70% 0.32% T3- 0.75% 0.36% T4- 0.80% 0.40% methionine. Body weight its changes, Hen Housed Egg Production (HHEP), egg (g), mass (g/day), feed conversion ratio found significantly (P<0.05) differed across during different phases experimental period. There significant overall body gain. Serum like albumin, globulin, creatinine, uric acid, triglycerides AST activity varied due EAAs CP diet. So it concluded that containing (T1) is adequate for optimum indices
