The effect of sex and growing phases on growth performance and carcass characteristics of local muscovy ducks (Cairina moschata)

The experiment was a 2x3 factorial design. The first factor was the duck’s growing periods with split phases (5-8 weeks old and 9-12 weeks old) and whole phase (5-12 weeks old). The second factor was the sex of birds, with three treatments, male birds, female birds and balanced for sex.
