Cranium morphometry for distinguishing male and female Muscovy duck (Cairina moschata) before sexual maturity

Gender determination of Muscovy duck as early possible is essential for the efficiency and effectiveness production. This study aimed to determine morphometric differences in prepubertal male female (Cairina moschata) predictors gender. used a split-plot design, with observed variables cranium length, width height, mandibular rostrum length width. total 80 samples heads consisting 40 heads, ten each age group 2, 4, 6, 8 weeks, respectively. Results showed that width, height cranium, lengthand were greater males (p <0.05) than those females all groups. It could be concluded size ducks head was ones at same age; thereby, it distinguish Based on morphometrics, further can also conducted measure other body parts apart from cranium. In addition, necessary measurements poultry basis identifying sex.
