ABSTRACT

Poultry dropping upgraded with maggot at different periods were evaluated for microbial quality. Poultry droppings were divided into five portions; each portion was exposed to house fly so that they can breed maggot under the following periods, 0 hour, 24 hours, 48 hours, 72 hours and96 hours. The 0 hour was not exposed to house fly; it was used as a control. Each portion of the sample was evaluated microbiologically at 0 hour, 24 hours, 48 hours, 72 hours and 96 hours. Ten grams from each sample were serially diluted. Dilution iO4was plated through a pour plate method. Fungi and Bacteria colonies were counted. All isolated organism were also identified. The result showed that 72 áolony forming units (CFU) were counted at 0 hour, 142 at 24 hours, 168 at 48 hours, 176 at 72 hours and 146 at 96 hours for bacteria. For fungi, 30 CFU were counted at 0 hour, 42 at 24 hours, 66 at 48 hours, 44 at 72 and 25 at 96 hours. The bacterial isolated included Streptococcus, Pseudomonas, E. colt Staphylococcus, Bacillus, Proteus and Clostridium. Also the fungi isolated from the samples included Aspergellus nigre, Aspergellus flavus, fusanum, penicillium, Geotrichiumand Rhizo pus. Production of good quality maggot upgraded poultry droppings was achieved at 48 hours; at this stage, it was observed that the poultry droppings upgraded with maggot was at its best quality because at this stage, there was rapid multiplication of microbes (Bacteria and Fungi). At 72 hours, the microbes' production started reducing, while the production of microbes dropped at 96 hours. Monitoring the growth of the microbes from 0 hour to 48 hours, it was observed that they were increasing rapidly, while at 72 hours, the increase started reducing, while at 96 hours, it dropped. At 48 hours, most of the harmful organisms were eliminated because of their vulnerable nature to harsh environment (outside the enteric environment) examples include E coli and Clostridium. Therefore, harvesting the maggots upgraded poultry droppings at 48 hours after exposure to house fly is recommended as a safe period for use as feed ingredient.
