Feather meal as a sustainable protein source for aquaculture in Bangladesh: Economic implications
Journal Title: Journal of Aquatic Research and Sustainability - Year 2024, Vol 1, Issue 1
Abstract
The aquaculture industry is primarily burdened by the costs associated with feed. It is fundamentally dependent on fish meal derived from wild-caught sources as the primary source of protein. With the widespread adoption of alternative feed ingredients for sustainable production, this study evaluated the use of poultry feathers as feed ingredients to produce hydrolyzed feather meal (HFM) and its economic implications in Bangladesh. Samples were collected from the poultry markets of Dhaka city and hydrolyzed using formic acid for hydrolyzed feather meal (HFM) contains a higher percentage of crude protein nutritional analysis. A questionnaire survey was executed to evaluate the market dynamics associated with poultry waste. It was observed that the city generates approximately 1000 metric tons of poultry waste every day. Among them, 95% of the waste is thrown away. It was discerned that 0.5 metric tons of feather meal could be generated using one ton of raw feathers. Annually, 3000 metric tons of feather meal could be produced with a value of 0.9 million US$. The HFM contains a higher percentage of crude protein (86.53±0.02%) with crude fat (5.03±0.03%). It contains most of the important amino acids that are beneficial for the growth of fish. The price of the HFM was estimated at 0.27 to 0.30 US$ per kilogram, notably lower compared to fish meal (1.1 US$), and bone meal (0.7 US$). The physical properties of the HFM were found satisfactory. Thus, domestically sourced hydrolyzed feather meal could be used as a feed ingredients for aquaculture operations to reduce feed costs. HFM has the potential to be utilized as a cost-effective feed ingredient, thus lowering overall feed expenses, and presenting a substantial commercial potential.
