Abstract:
Kamrupa is one of the newly improved variety of chicken which has been developed by the Assam Agricultural University. It is suitable for backyard farming system and highly adaptable in climatic condition of Assam. The present study was conducted on 500 newly introduced Kamrupa and 500 local birds. Under Tribal Sub Plan project, these birds were reared in backyard system at Udalguri district of Assam. Fifty women from five villages of the district were selected and provided with day old Kamrupa birds (100 nos./woman). Performance parameters viz age at sexual maturity, egg production, egg weight, mortality rate, and carcass traits were recorded and analysis was done following standard method. At 40^th week of age, the body weight of Kamrupa and local birds was found to be 2067.43±10.50 and 985.75±9.34 grams, respectively. Age at first egg laying was found to be 178.50±1.25 days in Kamrupa and 234.68±2.50 days in local birds. Annual egg production of Kamrupa and local bird was recorded as 138±2.10 and 76±1.50 numbers, respectively. The benefit cost ratio (BCR) was recorded as 1.42:1 and 1.20:1 at 20 week of age (male Kamrupa and local male bird) whereas it was found that the value for female Kamrupa and local female bird w.r.t BCR as 1.52:1 and 1.37:1. Though the performance of local birds is poor than the improved variety i.e Kamrupa but adaptability is very outstanding.
