Experiments will be designed to replace ration composition with spent grain, yeast, maggots and earthworms. Experiments with BSG will be compared with a control using commercial formulated poultry feed using two replicates of 20 broiler chickens each in each treatment, from zero day to eight weeks. Feed intake is the difference between the offered amounts of feed and the leftovers. Weekly live-weight maybe done using individual chickens or by weighing the group together. Feed conversion ratio is the feed consumed over live-weight gain.
Economic production is the feed cost per kilogram live-weight.
Experiments with maggots and earthworms will be conducted for scavenging chickens. The Poultry Section of School of Agriculture currently has facilities for research and experience. This can be applied to other breweries that are located in similar climatic conditions. Experiments with waste water are targeted to produce a wastewater that can meet international standards for discharge of brewery waste waters. Experimentation with earthworms and maggots will provide information on a new source of protein to replace fish meal and may possibly also provide a local source of exogenous enzymes which can help small-scale poultry farms attain better economic returns.
