Therefore, in the post antibiotics ban era, there is a need to look for alternatives, which can safely and efficiently replace antibiotics as growth promoters in poultry. The broad objective of the experiments were to determine the effect on biological performance of broiler birds offered diets containing low density protein, calcium and phosphorus by supplementation of direct fed microbial (DFM)/ probiotics isolated from leopard feces both under normal and stressful management conditions. After, isolation, purification and culturing of direct fed microbial from leopard feces procured from Gopalpur Wildlife natural Park – Palampur, the microbes/ DFM (Probiotic) namely Lactobacillus and Streptococcus were offered in low density nutrient viz. protein, calcium and phosphorus, formulated diets to broiler birds in sequentially conducted trials of 3 batches from 1 to 42 days of age under varied management protocols devised. It was found that that DFM supplemented broiler birds offered experimental formulated nutrient (Ca and P) deficient diet reared as per standard and poor management protocol exhibited higher growth and biological performance viz. low cholesterol, higher dressing percentage and low mortality by maintaining a higher count of beneficial microflora in the gastrointestinal tract and increase in nutrient utilization (Ca and P) through improved intestinal enzyme activities and nutrient availability. Effect of isolated DFM/probiotic was more pronounced when the birds were offered mineral (Ca and P) deficient (10 and 20%) diet Similarly supplementation of isolated DFM to broiler birds offered experimental formulated protein deficient diet could not overcome stress because of multiple managemental stress factors leading to poor colonization and growth and thus could not exert competitive exclusion vital to over come stress. Further, it was found that isolated DFM/Probiotics did not support the broiler birds to grow to its full genetic potential when challenged with multiple nutritional and management stress factors. At the farmer level supplementation of isolated DFM to the broiler birds significantly (P<0.05) improved the feed conversion ration and exhibited numerically higher gain in weight.
