Growth parameters and meat quality of Pekin ducks fed on different level of dried distillers grains with solubles

The experiment was carried out on 160 commercial Pekin ducks, strain P55. At the day of hatching birds were sexed, marked individually, weighed and divided randomly into four equal groups (four sup-groups, each). From Day 1 to Day 21 all birds received the same commercial feed, while from 4th to 8th week of rearing were fed in the following feeding groups: control, fed with commercial feed and experimental: with 15 %, 25 % and 30 % inclusion of dried distillers grains with solubles (DDGS). At 8th week of rearing from every group five males and five females were selected semi-randomly, slaughtered conventionally and slaughter yield, carcass composition and physicochemical meat characteristics were evaluated. Results from this study showed that Pekin ducks can be fed on diets containing up to 25 % DDGS without any significant decrease in slaughter yield, muscles contents and breast meat quality. Higher DDGS level (30 %) caused significant (P
