Abstract

The research objective was to assess the chemical and microbiological properties of broiler litter raised in broiler closed house at different altitudes. The design used was a completely randomized design with 3 treatments and 5 replications. The treatments consisted of T1 (broiler closed house at an altitude of <100 meters above sea level (masl), T2 (broiler closed house at an altitude of 100 - 300 masl) and T3 (broiler closed house at an altitude of 300 - 500 masl). The results showed that the difference in the altitude where broilers were raised had no significant effect on moisture, ash, extract ether (EE), crude fibre (CF), nitrogen free extract (NFE), total digestible nutrients (TDN), cuprum (Cu), lead (Pb), mercury (Ag), lactic acid bacteria (LAB), Salmonella, E. coli, Clostridium sp., antibiotic contamination (below the threshold) and predominance of gram-positive bacteria. The results of water content 22.71-24.65, crude protein 13.13-13.47, Pb 35.15-47.80 ppm, Cu 102.46-136.96 ppm, LAB 3.48 - 7.00 x 106 cfu/g. In conclusion, the differences in the altitude did not affect the chemical and microbiological properties of broiler litter. © 2021. All Rights Reserved.
