Assessing the impact of supplementing bacteriophages to increase laying hen production performance

Abstract

A study was conducted to evaluate the effect of supplementation of Bacteriophage on the production performance of Rhode Island Red Laying Hens. A total of 120 Rhode Island Red laying hens were randomly divided into 5 treatment groups of 24 each, with three replicates in a completely randomised design. The included treatments were (i) T1 (Control) without antibiotics and bacteriophages, (ii) T2 was supplemented with antibiotic (Oxytetracycline@50g/q of feed) and T3, T4 and T5, bacteriophage was supplemented at @0.20, 0.25 and 0.30 and ml/litre of drinking water, of drinking water, respectively. Dietary supplementation of antibiotics (oxytetracycline @ 25mg/kg diet) significantly (P
