White Pekin ducks can be reared under intensive rearing system for meat and egg production. Depending upon the availability, duck farmers use different types of cereals for feeding their ducks. Therefore, a study was conducted to find out the performance of White Pekin ducks during mid phase of layingfed on wheat and/or broken rice based diets under intensive rearing system. White Pekin laying ducks (45; 41 weeks old) were divided into three groups. Three types of diets without (BR-0) and with broken rice (BR), replacing 50 (BR-50) and 100 (BR-100) per cent of wheat were prepared and offered randomly to the above three groups till the ducks attained 52 weeks of age under standard feeding and management practices. The total egg production (dozen) and duck day egg production (DDEP) % were higher in BR-50 group (4.51 and 64.44) than
the BR-100 group (3.85 and 55.00); however, both were similar to BR-0 group (4.09 and 58.49). The total feed intake (12.55-13.80, kg) and feed conversion ratio (feed consumed in kg per dozen eggs produced) (2.93-3.31) were similar among the groups. The cost (Rs.) per egg was lower in BR-50 group (7.79) than the BR-0 group (8.32) and BR-100 group (8.71). The egg weight in BR-50 group (76.61 g) was higher than the BR-0 group (75.42 g); however, both were similar with BR-100 group (76.19 g). There was no significant difference in the egg shape index (68.22-69.69), albumen index (0.13-0.14) and yolk index (0.42-0.44) among the groups. The
However, the Haugh unit in BR-100 groups (87.32) was lower than BR-0 group (89.90); but both were similar with BR-50 group (89.56). There were no significant differences in the percentage of albumen (55.09-55.71), yolk (31.75-32.38) and shell (12.45-12.63) among the groups. Similarly, the shell thickness with membrane (0.50-0.52, mm) and without membrane (0.43-0.44, mm) were also similar among the groups. It can be concluded that White Pekin ducks can be raised on wheat and/or broken rice-based diets during mid phase of laying under intensive rearing system; however, mixture of wheat and broken rice in equal ratio increased the performance and was economical.
