The observed variables were collected data analyzed by ANOVA Duncan's test. results showed that various feeding timing techniques from starter feed (BR1) grower (BR2) did not make a significant difference (p>0.05) in broiler slaughter fat. Each these weights is range 2617.86 – 2754.24 g/head; 2010.51 2076.69 g/head or 75.00 76.80%; 41.70 44.40 g/head. It can be concluded all when changing types BR1 BR2 carried out breeders, however, economic value must considered because two have different prices.
