Comparative production performance and egg quality of Kuzi Ducks (Anas platyrhynchos) and its crosses with Khaki Campbell

Abstract

Comparative performance of Kuzi ducks and its two crossbreds with Khaki Campbell, viz. Kuzi × Khaki Campbell (DK) and Khaki Campbell × Kuzi (KD) were carried out in respect to various production, egg weight, age at different production level and egg quality traits. The laying period body weight showed significant difference between the three genetic groups, irrespective the age of measurement and Kuzi duck recorded significantly higher body weight than the two crosses. The crossbreds attained 50% duck day production significantly earlier as compared to Kuzi. Egg production per bird and average duck day production % during different periods differed significantly and the crosses recorded higher egg production than the Kuzi. DK laid more than 300 eggs up to 72 weeks of age. The average duck day production % from 72 to 80 weeks of age in both the crosses were 80% or more, indicating that the crosses may be used for second cycle for egg production. Egg weight recorded at different weeks of age showed significant difference between genetic groups and the egg weight were higher in Kuzi than the crosses. As the age advanced, the egg weight increased. Egg quality traits measured at different weeks of age showed significant difference between genetic groups and within genetic groups at different ages for some traits. The egg quality decreased as the age advanced. The study indicated that the crosses of Kuzi and Khaki Campbell may be used for higher egg production with good quality eggs.
