Abstract:

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. The birds in treatment groups T2, T3 and T4 were fed with control diet supplemented with 1, 2 and 3 per cent yeast extracted nucleotides, respectively from day 1 to 14 days and rest of the day upto 42 days control diet was fed. The birds in treatment groups T5, T6 and T7 were fed with control diet supplemented with 1, 2 and 3 per cent yeast extracted nucleotides, respectively from day 1 to 28 days and rest of the day upto 42 days control diet was fed. The birds in treatment groups T8, T9 and T10 were fed with control diet supplemented with 1, 2 and 3 per cent yeast extracted nucleotides, respectively from day 1 to 42 days. The results of feeding YEN on gut microflora evident that feeding of YEN at 2 and 3 per cent in birds from 14 days till 42 days resulted in significant (P≤0.05) decrease in pathogenic E. coli and increase in beneficial Lactobacillus. However, feeding YEN at 2 and 3 per cent up to 28 days was superior compared to 14 days and no difference could be observed between 28 and 42 days feeding of YEN. Hence, it is advocated that feeding YEN at 2 or 3 per cent up to 28 days would have better effect on gut microflora in broilers.
