Abstract

The research for predicting of carcass weight, percentage of carcass  and back fat thickness of male Duroc pig based on their age was done on one hundred and twenty male Duroc pigs.  The pigs were divided into four different groups of their aged: A (240-270 days), B (271-300 days), C (301-330 days) and D (331-360 days). Survey  method was done by using purposive quota sampling in Mabar Slaugther House, Medan. The variables observed were carcass weight, percentage of carcass, and back fat thickness of male Duroc pig. The prediction of variables which correlated with their aged were measured by using regression analysis. The result indicated that there was closely relation between animal age with carcass weight, percentage of carcass, and back fat thickness of male Duroc pig (P<0.01). The correlation coefficients were 0.989; 0.891 and 0.957 respectly.

Abstract

The purposed of this research was analyzed the relationship of pigs age with internal and external non carcass weight of male Duroc pigs. The experiment has been carried out on one hundred and twenty male Duroc pig, which consisted of four aged groups : A (240-270 days), B (271-300 days), C (301-330 days) and D (331-360 days). The method of this research was survey method by purposive quota sampling in Mabar Slaugther House, Medan. The variables were observed of internal and external non carcass weigth (head and foot) of male Duroc pigs. The relation of animal age and variable measured is used the quadratic regression analysis. The result indicated that there are closely relation (P<0,01) between animal age with internal and external non carcass weigth (head and foot) of male Duroc pig with correlation coefficient of 0.953; 0.992 and 0.950.
