The present experimental evaluation was to assess the effect of feeding Shrimp waste meal as a replacement for fish meal on serological, hematological parameters and carcass traits in broilers. A growth trial was conducted for 42 days using 375 commercial day old Chicks which were distributed randomly to five treatments with three replicates of twenty five birds each. In pre-starter diet fish, meal contribution to the dietary crude protein was replaced with shrimp waste meal at 0% (T1), 20% (T2), 30% (T3), T2 + synthetic lysine and methionine (T4), T3 + synthetic lysine and methionine (T5). In starter and finisher diets the shrimp waste meal protein was added up to the 0% (T1), 50% (T2), 100% (T3), 50% + synthetic lysine and methionine (T4), 100% + synthetic lysine and methionine (T5). In pre-starter and starter phases no significant difference was noticed regarding levels of serum total protein (g/dl), albumin (g/dl), globulin (g/dl), glucose (mg/dl) and cholesterol (mg/dl) among treatments (T1 to T5). In finisher phase also there was no significant difference in levels of serum total protein (g/dl), albumin (g/dl) and glucose (mg/dl) among treatments, but the serum cholesterol levels (mg/dl) and globulin levels (g/dl) were found significantly (p < 0.01) higher in birds fed T1diet than birds fed other diets (T2, T 3, T4 and T5). Non significant differences were noticed among treatment groups regarding RBC count during the three phases of the study. During pre-starter phase the WBC count (103/μl) was significantly higher (p < 0.01) in the birds fed with the diets T2, T3, T4 and T5 when compared to the birds fed with T 1( control diet). During starter and finisher phases the WBC count (103/μl) was significantly higher (p < 0.01) in the birds fed with the diets T2 and T3than the birds fed with T 1, T4 and T5. During the pre-starter and starter phases. Lymphocyte (%) count was significantly higher (p < 0.01) in T2 and T3 than in T1, T4 and T5 fed birds. Whereas during the finisher phase there was no significant difference among treatments. At the end of growth trial, the live weight gain, hot carcass weight and the dressing percentage were found significantly (p < 0.01) higher in birds fed T 4 diet when compared to birds fed other diets. The liver, gizzard and heart weights (g) were found significantly (p < 0.01) higher in birds fed T4, T2, and T1 diets when compared to T 3 and T5 group. The results of the present study depicts that the Protein from FM can be safely substituted up to 30% with the SWM protein in pre-starter and up to 50% in starter and finisher broiler diets along with the supplementation of synthetic amino acids (lysine and methionine).
