ABSTRACT The effect of additives used in the feed of broilers on anaerobic bio-digestion of poultry litter was evaluated. Four diets were used: NC: negative control; DFM: NC + 500 ppm direct-fed microbials (DFM) containing Bacillus subtilis and Bacillus licheniformis; ENZ: diet formulated with an enzyme blend (20 ppm phytase, 200 ppm protease and 200 ppm xylanase); DFM+E: ENZ + DFM. Substrates for the anaerobic bio-digestion were prepared with litter from each treatment, containing 4 % total solids (TS). These were used in 16 continuous bio-digesters with a 2 kg d−1 load, to determine the production and potential biogas production and composition during an 85-day period. Influent and effluent samples were collected for the amounts of TS and volatile solids...

A comparative study of biogas production of different proportions of poultry wastes  and cow dung was conducted under the same operating conditions.  The study was based on Completely Randomsied Design replicated three times.  Three different mix ratios of poultry wastes and cow dung were tested (namely 3:1, 1:1 and 1:3) and all of them were diluted with the same amount of water.  Each treatment was replicated three times.  Biogas production was measured for a period of seven days and volume of gas produced was determined by water displacement method at room temperature of 25 – 30oC.  Biogas production started on the second day, and  reached apex on the sixth day for Digester A (cow dung:poultry wastes r = 1:3).  Production reached its peak on the seventh...
