The use of body measurements to estimate body, carcass, meat and bone weight of young Jawarandu bucks

Abstract

Abstract A study was carried out to determine the relationship between body measurements and body weight, carcass weight and meat weight of Jawarandu bucks in Indonesia. This study used 103 young Jawarandu bucks (6–8 months old). The samples of the young Jawarandu bucks were taken using purposive sampling method in, Salatiga City. Central Java Province, Indonesia. The parameters observed were body height at withers (WH), body length (BL), chest girth (CG), chest width (CW), chest depth (CD), body weight (BW), carcass weight (CW), meat weight (MW), bone weight (BnW) and meat-bone ratio (MBR). The data obtained were analysed by correlation and regression models. In this study, body measurements were highly correlated (P<0.01) with BW, CW, MW and BnW (r = 0.52 – 0.87). The regression model showed that BW, CW, BnW and MBR were affected by WH, BL, HG; CW and CD. The multiple linear regression between body measurements and meat weight showed that the equation for predicting MW of young Jawarandu bucks (R2 = 0.91) was Y = -14,53 + 0,10X1 + 0,34X2 + 0,07X3 + 0,06X4 - 0,53X5. In conclusion, body size could be used to predict the body, carcass, meat and bone weight of Jawarandu bucks.
