The purpose of this study was to investigate the closed-house cage density near the outlet that affected the production of carcass, non-carcass, and abdominal fat of finisher phase broilers and to ascertain the number of closed-house cage density that could produce the ideal amount of carcass, non-carcass, and low abdominal fat. The experiment employed a completely randomized design with four treatments: T0 (10 birds per square meter), T1 (12 birds per square meter), T2 (14 birds per square meter), and T3 (16 birds per square meter). It was replicated five times using different numbers of broilers in each replication depending on the cage density. The observed variables were live weight, carcass weight, percentage of carcass, percentage of non-carcass, and percentage of abdominal fat. Data were subjected to analysis of variance and further tested with Duncan's multiple-range test. The study was carried out for 35 days at Farm H. Noto Miharjo in Adiwarno Village, Buayan District, Kebumen Regency, Central Java. The research results showed that the live weight, carcass weight, and carcass percentage were significantly impacted by closed-house cage density at the area near the outlet, although non-carcass percentage and abdominal fat were not significantly impacted. A closed house cage density of 12 birds per square meter at the area near the outlet can provide an optimal production of carcass, non-carcass, and abdominal fat.

This research aimed to see how the impact of time to replace BR 1 with BR 2 ration to slaughtering weight, carcass weight, and abdominal fats of broiler. This research was an experimental method using Complete Randomized Design (CRD) with five treatments and five replication. These treatment consisted of P1: giving BR 1 (1 to 42 days old), P2: giving BR 2 (1 to 42 days old), P3: giving BR 1 (1 to 7 days old), and giving BR 2 (8 to 42 days-old), P4: giving BR 1 (1 to 14 days-old) and giving BR 2 (15 to 42 days-old), P5: giving BR 1 (1 to 21 days-old) and giving BR 2 (22 to 42 days-old). The observed variables were slaughtering weight, carcass weight, and abdominal fats of the broiler. The collected data were analyzed by ANOVA and Duncan's test. The results showed that various feeding timing techniques from starter feed (BR1) to grower feed (BR2) did not make a significant difference (p>0.05) in broiler slaughter weight, carcass weight, and abdominal fat. Each of these weights is in the range of 2617.86 – 2754.24 g/head; 2010.51 – 2076.69 g/head or 75.00 – 76.80%; and 41.70 – 44.40 g/head. It can be concluded that all techniques when changing feed types from BR1 to BR2 can be carried out by breeders, however, the economic value of these techniques must be considered because the two types of feed have different prices.
