Two metabolic trials were conducted with broilers at 4 th and 6 th weeks of age to study the effect of dietary supplementation of Lactobacillus sporogens and Zigbir on the production performance of commercial broilers. In experiment graded levels of Lactobacillus sporogens (0.02% or 0.04%), 0.02% Lactobacillus with 0.025% Zigbir and 0.04% Lactobacillus with 0.05% Zigbir were supplemented in the basal diet to formulate treatment diet no. 1 to 5. The five experimental diets used in the experiment were isocaloric and isonitrogenous. Each diet was tested in triplicate groups of 15 broilers each for 6 weeks from week-old age. Estimations were made for the per cent utilization of organic nutrients, mineral balances and the Hematological profile viz hemoglobin, TEC, TLC, PCV and the erythrocyte indices like MCV, MCH and MCHC in experimental birds.
The percent utilization of dry matter, fat, protein, calcium and phosphorus were not significantly affected by the supplementation of Lactobacillus and Zigbir in the isocaloric and isonitrogenous broiler’s diet. A positive balance of nitrogen, calcium and phosphorus was observed in all the treatment groups, suggesting the safe inclusion of Lactobacillus and Zigbir in broiler’s diet. Similarly the various hematological parameters viz haemoglobin, PCV, TEC, TLC and various erythrocyte indices also did not reveal any significant adverse effect of Lactobacillus and Zigbir on poultry diets.
