An experiment was conducted to evaluate the effects of feeding graded levels of Yeast cell extracted nucleotide (YEN) at different age intervals on Gut (Intestinal) microbial load of commercial broilers. In a completely randomized design, 300 day-old straight run commercial broiler chicks were assigned to ten treatments with each treatments consisting of three replicates with ten chicks in each. Basal diet (control) T1 was prepared without supplementation of yeast extracted nucleotides for day 1 to 42 days of experimental period. | Effect of feeding graded dietary levels of yeast cell extracted nucleotides YEN at different age intervals on gut Intestinal microbial load of commercial broilers
