Lysine Requirement of Male White Pekin Ducklings from Seven to Twenty-one Days of Age

A dose-response experiment with five lysine levels (0.65, 0.80, 0.95, 1.10, and 1.25%) was conducted to evaluate the lysine requirement of male White Pekin ducklings from 7 to 21 days of age. Two hundred and eighty, 7-day-old, male White Pekin ducklings were allocated to 5 experimental treatments, each containing 8 replicate pens with 7 birds per pen.

Pathological changes are found in the skeletal muscles. These show widespread hyaline necrosis of fibers, with edema and cellular reaction. The brain and other parts...
