Abstract
This research work was carried out to evaluate poultry waste as a potential feed for fish growth. The poultry droppings were collected for analysis. The parameter determined to ascertain the potential of this poultry waste were proximate analysis (Moisture, dry matter, ash, crude protein, fat, crude fibre and carbohydrate contents) and mineral nutrient composition (calcium, potassium, magnesium, sodium, copper, zinc, iron and manganese). The proximate analysis determined estimated moisture content to be 9.62±0.02%, dry matter 90.38±0.03%, ash content: 28.83±0.29%, crude protein: 21.34±0.16%, fat content: 2.61±0.13%, crude fibre:16.09±0.04, and carbohydrate: 21.53±0.03. The minerals nutrient composition for metals analysed is as follows; calcium: 2349.9±56.57mg/kg, potassium: 6239±572.76mg/kg. Magnesium: 1075.0±141.42mg/kg, sodium: 292.3±10.61mg/kg, copper: 104.8±7.07mg/kg, zinc: 395.0±7.07mg/kg, iron: 519.7±7.07mg/kg and manganese: 257.5±10.61mg/kg. However, based on the result for proximate analysis of the poultry waste analysed and mineral nutrients estimated compared with the mineral nutrient requirement of fish the results were not adequate for direct use as feed for fish. Thus the poultry droppings could only serve as feed or supplement for the conventional fish feeds use for fish to give excellent growth rate.Keywords: Poultry Waste, Feed, Fish, Proximate, Minerals, Parameters, poultry droppings
Highlights
The use of poultry waste as manure and other farm animal manure as feed for fish is not a new method
Poultry manure is a potential source of protein, it has attracted the attention of animal nutritionist all over the world because of its richness of protein, calcium (5.4%), phosphorus is K2O and magnesium as MgO (0.335%) other minerals (Ranjhan, 1980; SPFG, 1994)
A range of poultry by products are produced and re use in livestock feeds, including feather meal, blood meal, poultry litter meal etc. (Moller, 1980) and poultry waste are used as fertilizer and soil conditioners
Summary
The use of poultry waste as manure and other farm animal manure as feed for fish is not a new method. Integration of fish culture with livestock and crop farming is an ancient practice in China. The importance of poultry waste in aquaculture is relatively recent and the current interest in manure as a feedstuff is mostly due to the problem of waste disposal from intensive livestock and poultry operation. Apart from this problem it has been recognized that large amounts of nutrient are wasted which this work seeks to evaluate (Qureshi, 1965). The objective of this paper is to analyse poultry wastes as a potential feed supplement for fish growth
