Title : Utilization of apple pomace and spent mushroom compost as animal feed: A step forward to livestock and environmental sustainability

Abstract:

Apple pomace and spent mushroom compost, the byproducts/leftover of apple juice industry and mushroom industry, respectively, are generated in tonnes every year. Despite of their nutritional benefits, a very little percentage is utilized for animal feeding and rest is either dumped road side or landfills. Besides, underutilization of these nutritious agro-wastes, their direct release in the environment puts a great load on different elements of ecology in terms of high chemical oxygen demand. A scientific utilization of these agro-wastes individually or in combination may be employed for economic animal feeding. Where, apple pomace is a rich repository of water-soluble carbohydrates (10.30±0.07 gm/100gm DM), but low in crude protein (5.89±0.16 % of DM) and dry matter (14.73±0.08 %), the spent mushroom compost is rich in protein (12.75±0.12%) and has enzymes such as cellulase and xylanase to bio-fortify the wheat straw. In addition, apple pomace is rich in polyphenols and dietary fiber. Thus, a combination of apple pomace, spent mushroom compost in a specific way may not only provide an economic feed/feed ingredient substitute, but will also address the current situation of decreasing pasture lands and fodder availability to livestock and environmental load.

Talk will cover following:

  • Current scenario of agro-wastes and their sources and nutritional aspects
  • Current scenario of availability of animal feed and fodder and livestock sector
  • Current methods of disposal and impact on environment sustainability
  • Detailed aspects of apple pomace and spent mushroom compost
  • How apple pomace and spent mushroom compost can be utilized for animal feeding?
  • Challenges during utilization
  • Role in livestock economic rearing and sustainability
