Correlation between the Slaughter Weight and Carcass Weight of Cattle in Kebumen, Central Java

Abstract

The experiment was conducted to nd out the correlation between the slaughter and carcass weights of cattle (PO, SIMPO, and LIMPO) in Kebumen, Central Java. The materials were 180 cattle (male and female) were divided into three group of age i.e. 0-2.0, 2.5-4.0, and >4.5 years. The sex, age, and breed of cattle were observed before slaughtering. The carcass, meat, bone, and non carcass weights were observed after slaughtering. The data (correlation between slaughter, carcass, meat, bone, and non carcass weights were analyzed using simple and multiple regression analysis and analysis of variance (factorial pattern = 3 breed x 3 age x 2 sex) and the differences between means were tested by Duncan Multiple Range Test. The carcass, meat, bone, and non carcass weights were correlated negatively of PO (P<0.05). The slaughter weight were correlated positively with carcass and meat weights but it were correlated negatively with bone and non carcass weights of SIMPO (P<0.05). There were showed differences between breed cattle, sex, and age on slaughter, carcass, meat, bone, and non carcass weights (P<0.05). There were showed interactions between the breed with sex, sex with age, and breed with sex and age on bone weight, and non carcass weight (P<0.05).
