Chemical composition and amino acid profile of differently processed feather meal
Feather wastes represent potential alternative ingredients for animal
feedstuffs which can ameliorate the protein shortage for food and feed.
Previous attempts to provide information about the nutrient composition of
feather meal are either too complicated for rural livestock farmers in
developing countries or they provided incomplete information on chemical
composition. Washed feathers were subjected to different processing
techniques such as pre-soaking in distilled water, wood ash, 0.3M NaOH, a
mixture of wood ash and 0.3M NaOH, incubated at 37°C and boiled at 150°C for
60 minutes. Treated feather meals were analysed for chemical composition and
amino acid profile. The overall result showed that feather meal pre-soaked
with wood ash for 24 hr boiled at 150oC for 60 minutes, those pre-soaked with
0.3M NaOH and wood ash incubated at 37°C for 24 hr boiled at 150°C for 60
minutes and raw feather meal pre-soaked in distilled water for 24 hr boiled
at 150°C for 60 minutes gave better results. Wood ash and 0.3M NaOH and their
mixture could enhance the nutritional value of feather meal
