| description | In poultry diets, a requirement of crude protein is one of the most important
factors in poultry productivity. Besides, the Pekin duck requirement of crude
protein is still not clear. This experiment was conducted to determine the crude
protein requirement of Pekin duck on diet formulation by investigation of growth
performance, carcass trait, and analysis of blood parameter for a hatch to
21-day (d) of age. A total of 432 male White Pekin ducks were randomly allocated
to six levels of crude protein (i.e., 15%, 17%, 19%, 21%, 23%, and 25%) to give
six replicate pens per treatment with 12 ducklings per each pen. Body weight and
feed intake were measured weekly by calculating feed conversion ratio and
protein intake. Two ducklings each pen was euthanized via cervical dislocation
for analysis of carcass trait and plasma blood on 21-d of age. Data were applied
on both prediction linear-plateau and quadratic-plateau models by estimation of
the crude protein requirements. Data were applied on both prediction
linear-plateau and quadratic-plateau models by estimation of the crude protein
requirements. The level of crude protein requirements of Pekin ducks for 21 days
after the hatch was estimated to be 20.63% and 23.25% diet for maximum daily
gain, and minimum feed conversion ratio, respectively. |
