Discriminant analysis of sexual dimorphism in morphological traits of African Muscovy ducks

Abstract: SUMMARYSexual dimorphism was examined in 221 randomly selected adult African Muscovy ducks extensively reared in north central Nigeria using univariate and multivariate measures of body size and skeletal proportions. The body parameters investigated included body weight, 8 primary linear body measurements [breast circumference (BTC), thigh circumference (THC), body length (BDL), bill length (BLL), neck length (NKL),foot length (FTL), total leg length (TLL) and wing length (WNL)] and 4 morphological indices (ma… Show more

“…The results suggest that feasibility depends on both the traits measured and the time (in weeks of age) of measurement. This general result indicates that different morphological measurements display different discriminating power as observed in other studies (see, for example Yakubu, (2011), for Muscovy ducks; Perkins et al, (2009), for clapper rails and king rails).…”

“…YAKUBU et al (2011) citam que a análise de variância e a correlação são amplamente utilizadas para caracterizar relações fenotípicas e genéticas nos programas de melhoramento e conservação genética. CRUZ & REGAZZI (2001) atribuem ainda a análise multivariada como uma ferramenta interessante para redução de características a serem usadas em estudos posteriores.…”
