Multivariate analysis of the morphological traits of female duck, muscovy-duck and mule-duck

Abstract

The objective of this study was to evaluate the characteristics of morphometrical measurements in the female waterfowls. The animals used in this research were 90 ducks, 90 muscovy-ducks and 90 mule-ducks in Bulukumba district of Brebes regency, Central Java, Indonesia. Parameters measured were maxilla length, neck length, body length, chest circumstance, wing length, chest length, femur length and tibia length. The data were analyzed using the Statistical Analysis System ver. 9.1. Muscovy-duck generally had the largest of size, followed by mule-duck and then duck. The most discriminant variables were showed by chest length and chest circumstance. Muscovy-duck and mule-duck had closest genetic distance (3.974870) than both of the distance between duck and mule duck (14.10), and muscovy-duck and duck (24.73). The smallest errorness level in grouping was showed in duck 1% followed by 2% in mule-duck and 3% in muscovy-duck.
