MULTIVARIATE ANALYSIS ON PHENOTYPIC TRAITS OF BODY MEASUREMENT IN SWAMP BUFFALO ( Bubalus bubalis)

Abstract

The objective of this research was to study the relationship between body measurement and body weight and closeness among swamp buffalo at three populations in Central Java. The 110 heads of swamp buffalo measured were from 29 heads of Pati district, 56 heads of Kudus district, and 25 heads of Semarang city. Age of buffaloes used was 1-5 years old. The quantitative traits measured were body weight ( BW), body length (BL), shoulder height (SH), pelvic height (PH), chest depth (CD), chest circumference (CC), chest width (CW), Pelvic width (PW), and waist width (WW). The data was analyzed by using multivariate procedure of SAS ver 6. The results showed that best equation to estimate BW for male buffalo was Y= - 601,8 + 2,3 BL + 3,4 CD + 2,4 CC, while that for female was Y = - 644,5 + 2,8 BL + 1,6 CD + 2,9 CC. Swamp buffalo in Semarang-Pati showed the closer relationships compared to the Pati-Kudus Districts and to Kudus District-Semarang City.
