Abstract

This research aimed to determine the appropriate method for fermenting poultry manure as feed material and to evaluate the effects on catfish performance, water quality, and carcass chemical composition. In experiment 1, fresh manure (62.1%) was mixed with dried black soldier fly larvae (26.3%) and cassava flour (11.6%). Subsequently, multipurpose microbes (SBP®) were used to ferment 100 kg of mixed diet on anaerobic and semi-anaerobic media with different time (0 vs. 24 vs. 48 vs. 72 h). In experiment 2, fermented manure was produced using best method before pelleting. The manure was applied as substitution of commercial feed consisting of 0%, 15%, 25%, 50%. Approximately 100 fishes were maintained on 120 L tank and fed daily with 3% dry matter (DM) basis of body weight. In experiment 1, a longer fermentation period increased quadratic change (P < 0.05) in dry matter, organic matter, and crude protein, while ether extract increased linearly (P < 0.05). The anaerobic fermentation for 72 h reported the lowest pH, propionic acid, butyric acid, E. coli, and Salmonella spp. (P < 0.05), while the remaining treatment produced higher lactic acid, acetic acid, and LAB (P < 0.05). This fermentation was applied for diet production in experiment 2 since the substitution of basal diet using 50% fermented manure had no effect on performance, water and carcass quality (P > 0.05). Therefore, anaerobic fermentation for 72 h was the most favorable method for processing manure, which had the potential to substitute up to 50% of the feed for catfish without no statistically different in affecting performance, as well as water and carcass quality.
