Abstract:
Records on part year egg production of 106 Nageswari ducks belonging to Katigora Block of Cachar district and Ratabari Block of Karimganj district of Assam were utilized to predict annual egg production. Both simple and multiple regression equations were developed for studying the dependency of annual egg production up to 72 weeks (EP 72) of age on the basis of egg production up to 40 weeks (EP 40) and 56 weeks (EP 56) of age. The R2 values of these equations were 24.18, 71.71 and 71.73 percent on the basis of 40 weeks egg production, 56 weeks egg production and combination of both 40 and 56 weeks egg production respectively.
