40 one day old commercial layer chicks of BV 300 strain were randomly divided into two treatment groups with two replicates of 10 chicks each and reared under deep litter system of housing. Group T1 was positive control fed with the basal diet without any natural or synthetic source of antibiotics. Group T2 was test group fed with the basal diet supplemented with herbal liver tonic, Superliv @ 500g/ton of feed for a period of 0 to 38 weeks (supplied by M/S Ayurvet Ltd., Baddi, India). Superliv supplemented birds showed higher body weight throughout the experimental period as compared to unsupplemented control group. Hen housed egg production (HHEP) was also found to be higher in Superliv supplemented birds (75.02) as compared to control group (70.80). Feed efficiency per dozen eggs produced was also found to be better in Superliv supplemented group (1.51) birds as compared to control group birds (1.65). From the results of the study it can be concluded that Superliv may be added to layers diet to elicit growth performance and egg production performance in commercial layers.
