The present investigation is about the Front Line Demonstrations (FLD) conducted at farmer’s field on backyard poultry by Krishi Vigyan Kendra (KVK) - Koderma, Jharkhand, India. The impact of training on poultry farming was significant high and average knowledge score of the trainees increased from 3.22 to 8.58. The performance of dual purpose strain CARI-Nirbheek was better under backyard poultry farming. The overall mean body weight, the mean eggs production were significantly (P≤0.05) higher in CARI-Nirbheek birds than native birds. The overall mortality rate of CARI-Nirbheek birds were significant lower (P≤0.05) than native birds. The benefit cost ratio of rearing in CARI-Nirbheek was recorded 1: 3.01 per family. The income of small, marginal and landless poultry farmers were increased due to rearing of CARI-Nirbheek birds under backyard through low input and high output venture within a very short span of time. CARI-Nirbheek is one of the promising dual purpose strains of poultry, which can be popularized in rural areas of Koderma.
