摘要

Recent days, feed biotechnology is creating land mark differences among traditional and sustainable poultry formulations. Biotechnology is now enables us to incorporate useful additives in broilers ration like enzymes, probiotics and more absorbable mineral sources. Individual effect of each additive had been explored extensively but combined effect of chelated minerals, enzymes and probiotics was studied in this research for sustainable broiler production. The purpose of present study was to evaluate the effects of dietary supplementation of Nutri biyo® (Nb) on different growth and physiological parameters in broilers. A total of 240 day-old chicks were randomly divided into 4 treatments having 6 replicates each (10 birds per replicate). The treatments were T0 (basal diet), T1 (basal diet + 0.5 g Nb), T2 (basal diet + 1 g Nb) and T3 (basal diet + 1.5 g Nb). During starter, finisher and overall duration, growth performance was improved in group receiving the highest inclusion of Nb. Furthermore, total tract nutrient digestibility, immune organ index and meat quality (springiness, chewiness, adhesiveness, compression, shear force and hardness values, ) were observed significant (p < 0.05) in birds fed with 1.5 g of Nb as compared to control group on both 21st and 35th day. Antibody titers, carcass characteristics (carcass, thigh, heart, gizzard, back and proventriculus percentages), ileal digestibility (crude protein, dry matter, and ether extract) and bone measurements (tibia length, weight, wall thickness, and structural indicators) were improved (p < 0.05) by T3 group. Hematological parameters such as hemoglobin, packed cell volume, lymphocyte and red blood cell counts revealed significant increases in birds fed 1.0 and 1.5 g/kg. Other hematological parameters, crude fiber (ileal) digestibility, breast, liver, wings and pancreas weights remained unchanged. These findings suggest Nutri Biyo® at 1.5 g dose level as an effective feed additive for improving overall broiler performance.
