Scavenging Duck at Haor Basin: Plane of Nutrition and Response to Production

Animal Science

This study was designed to assess the basic nutrition of duck get from scavenge feeding and their response to egg production. Eight commercial duck farms were randomly selected from three Upazilla and data were arranged into complete randomized design. Significant (p<0.01) differences were found in flocks size (111 to 1200 duck), feed (40g to 100g /b/d), ME (95.37 to 246.95 KCal/b/d), CP (3.52 to 8.92 g/b/d) intake and FCR ( 3.26 to 1.88) value. The range of protein-energy ratio was 1:27 to 1:24 that was in below of standard leaded to poor performance in egg production. Only 37.5% flocks performed 55% to 65% egg production while 53.5% farms were in between 33% to 48% production level with standard egg size (60g). 20% farm possessed1000 to 1200 duck and earned BDT 1200 to 3500 per day while 80% farms reared 100 to 300 duck and earned daily BDT 300 to 500. Jinding took significantly more feed (44%), ME (53%) and CP (40%) but produced less egg than Khaki Campbell reflecting high production cost and low return (p = 0.02). Flock size should be with 300 ducks to generate family income from egg. Overall, water logged duck Khaki Campbell is better feed converter and egg producer at under underfed condition.
