Abstract

A study was conducted to determine the effects of different calcium and phosphorus levels on egg production performance of Philippine Mallard Ducks (Anas platyrhynchos L.) from 47 to 55 weeks. A total of sixty 47-week old Philippine Mallard Ducks were randomly distributed to five treatments with 12 replicates per treatment. The following levels of calcium and phosphorus were used: 2.21%, 2.68%, 3.15%, 3.62%, 4.10% calcium and 0.29%, 0.36%, 0.42%, 0.48%, and 0.55% available phosphorus. No differences (P>0.05) were observed in hen-day egg production and feed efficiency. Ducks fed with 4.10% calcium and 0.55% available phosphorus had lower (P<0.05) egg weight at 49-51 weeks. Increase (P<0.05) in shell thickness was observed in ducks fed with 3.62% calcium and 0.48% available phosphorus. This study showed that increasing levels of calcium and phosphorus had no effect (P>0.05) on hen-day egg production and feed efficiency but affected (P<0.05) egg weight, average daily feed consumption, and egg shell thickness.
