Effect of breeder and post-hatch dietary supplementation of sea buckthorn leaf meal on growth performance of coloured broiler during summer season

摘要

A study was conducted in colored breeder chickens and their post-hatch chicks on growth performance due to dietary supplementation of sea buckthorn leaf meal (SBTLM)during summer season. Total of 90colored breeder hens and 18viable cocks were randomlydistributed into three treatment groups: Control (basal), standard breeder diet (BB) (BIS, 2007); basal+0.5% and basal+1.0% SBTLM.A total 90 chicks from each breeder groups were further subdivided into three groups each groups having three replicates of10 birds. Control (basal), broiler starter till 4 weeks, broiler finisher till 8 weeks of age, (BP) (BIS 2007); basal+0.5% supplementation and basal+1.0% supplementation of SBTLM. Average body weight gain (g) during 0-4 and 0-8 weeks were significantlyhigher (P<0.05) in breeder diet groups BB+0.5%SBTLM and BB+1.0% SBTLM dietary supplemented groups compared to BB. Similarly, weekly body weight gain of 0.5% SBTLM supplemented group during post hatch and obtained from breeders subjected to 0.5% SBTLM supplementation was significantly (P<0.01) higher during 0-4,5-8 and 0-8 weeks of experimentation. The overall FCR (0-8 weeks) were significantly improved (P<0.05) in both SBTLM supplemented groups in breeder diet as well as in post hatch diets. It was alsoobserved that supplementation of 0.5%SBTLM had synergistic effect in improving the FCR of coloured breeder birds. Results of study concluded that dietary supplementation of 0.5% SBTLM in both breeder and post hatch chicks resulted in better growth performance and FCR during the study period.
