The present experiment was conducted to study the effect of sea buckthorn leaf meal (SBTLM) supplementation on hen house and hen day egg production in ninety coloured Chabro adult breeder hens and 18 viable cocks in 1:5 sex ratio were randomly distributed into three dietary treatment groups: Control (Basal), standard breeder diet (BIS, 2007); basal+ 0.5% and basal+1.0% SBTLM. The average egg production during 5th week were significantly higher (p<0.01) in basal diet+1.0% SBTLM supplemented group (72.86) as compared to basal diet+0.5% SBTLM and control or basal diet groups (56.67 and 62.3). However, during 11th and 12th week of experimental feeding, the weekly hen house egg production were significantly higher (p<0.01) in both the SBTLM supplemented groups than the control group. The overall egg production up to the 12th week of experimentation were significantly higher (p<0.01) in basal diet +1.0% SBTLM supplemented groups as compared tocontrol group. During the experimental study period, there was no mortality in any treatment group. Hence, the hen day egg production per week and phase wise hen day egg production per week was equal to the hen house egg production per week and phase wise egg production per week, respectively.
