Effect of feed supplementation on chemical composition of meat of three genotypes of scavenging ducklings in coastal areas of Bangladesh
Keywords:Chemical composition, coastal region, duck
The present study was conducted to evaluate the chemical composition of three genotypes of scavenging ducklings (Muscovy, Pekin and Desi White) in coastal areas of Bangladesh. Three ducks from each genotype were slaughtered at 6, 10 and 14th week of age. The results indicated that dry matter yield was highest in Muscovy (40.91 and 44.40) followed by Pekin (39.30 and 44.31) and Desi White (35.67 and 41.82) for control and supplemental group, respectively at 14th week of age. The concentration of crude protein was highest in Muscovy (18.76 and 19.90), intermediate in Pekin (18.40 and 19.66) and the lowest in Desi White (17.20 and 19.14) for two feeding regimes at 14th week of age. The ether extract content varied from 17.21 to 23.16. Genotype and feed showed significant effect (p<0.01) on crude protein and ether extract content of duck meat at 10 and 14th week of age. The ash content was highest in Muscovy followed by Pekin and Desi White throughout the experimental period. Genotypes, feed and interaction between genotypes and feed showed no significant (p>0.05) effect on ash content at 14th week of age. Genotypes and feed showed significant effect (p<0.01) but the interaction between genotype and feed had no significant effect (p>0.05) on DM and moisture content of duck meat.
