The present experiment was conducted to study the effect of dietary supplementation of sea buckthorn leaf meal (SBTLM) in breeder chicken and their post hatch growth performance and serum biochemical attributes during summer season. Ninety coloured Chabro breeder hens and eighteen viable cocks in 1:5 sex ratio were randomly distributed into three treatment groups: Control (Basal), standard breeder diet (BB); basal+0.5% and basal+1.0% SBTLM. Thereafter, ninety chicks from each breeder groups were further subdivided into three groups: Control (Basal), Broiler starter till 4 weeks, broiler finisher till 8 weeks of age, (BP); basal+0.5% supplementation and basal+1.0% supplementation of SBTLM. The weekly body weight gain (g) was significantly higher (P<0.05) in 0.5% SBTLM supplemented breeder group during 0-4 week and significantly higher (P<0.01) in 0.5% SBTLM supplemented post hatch group during 0-8 week of the study period. Similarly, weekly FCR were also significantly better (P<0.05) in 0.5% SBTLM supplemented breeder group during 0-4 week and significantly higher (P<0.01) in 0.5% SBTLM supplemented post hatch group during 0-8 week of the study period. Serum HDL was significantly higher (P<0.05), where as serum cholesterol was significantly lower (P<0.05) and serum triglyceride was significantly lower (P<0.01) in both post hatch SBTLM supplemented groups as compared to control group. No significant difference were observed in other serum biochemical attributes viz. total protein, albumin, globulin, A/G ratio, uric acid, creatinine, SGOT, SGPT and ALP among the treatment groups. Thus, it may be concluded that dietary supplementation of sea buckthorn leaf meal in coloured chicken @ 0.5% resulted in higher phase wise body weight gain, FCR, serum HDL, lower cholesterol and triglyceride without any adverse effect on other biochemical attributes.
