Effect of organic and nano copper at reduced dietary levels on biochemical profile and immune response of Giriraja and Swarnadhara birds

Experiments were conducted to assess the effect of dietary organic and nano-particle forms Cu at reduced levels on serum biochemical profile immune response in improved chickens. Giriraja chicks (n=420) assigned starter (1-6 weeks) grower diets (7-10 Swarnadhara breeders (n=224) breeder (28-48 during experimentation. Control diet prepared for each phase was supplemented with inorganic CuSO4 as per ICAR recommendation test 100 (OC-100), 75 (OC-75) 50% (OC-50) or nanoparticle (NC-75), 50 (NC-50) 25% (NC-25) control. During phase, blood samples collected from 8 birds treatment. The total protein globulin higher OC-50 lower NC-50 3rd 48th week. Glucose content control compared group week NC-75 all other groups 10th Total cholesterol OC-100 Serum albumin, calcium, phosphorus, triglyceride, creatinine, SGOT SGPT similar among 3rd, Antibody titre against Newcastle disease virus OC-75 infectious Bursal week, while It concluded that inclusion Nano had no adverse except nano chicken age.
