Abstract

An experiment was conducted to investigate the performance and production cost of Pekin ducklings fed varying levels of dietary protein. One hundred and twenty ducklings in four separate groups received either 16, 18, 20 or 22% CP in the starter period (day-old to 3rd week of age). These four groups ate either 12, 14, 16 or 18% CP respectively during the grower-finisher period (4th week to 12th week of age). The results of the study indicated that in a tropical country like Bangladesh, the protein needs of Pekin ducklings should be satisfied depending on the age at which the birds are to be marketed. If the ducklings are to be marketed at 6 weeks, 22/18% CP would be sufficient. When the marketing is aimed at 9 weeks of age, 20/16% would be adequate. For ducklings which are to be marketed at 12 weeks of age, a protein level of 18/14% would be required. All these results should help the producers to keep production cost to a minimum. The exceptional capacity of ducklings for compensatory growth would help keep birds on low protein levels if they are reared upto 9 or 12 weeks before marketing.
