Proximate evaluation of Azolla pinnata as sustainable feed supplement for poultry

Abstract

Azolla is a free floating fern rich in proteins, essential amino acids, minerals, vitamins (Vitamin A, B12, Beta carotene), bioactive substances and biopolymers. An attempt was made to evaluate the proximate value of Azolla pinnata as a feed for poultry. Azolla was cultivated following the NARDEP method. After harvesting it was sundried and stored in polyethylene bags and was further analysed for proximate principles. The dry matter content was 90.03 %, 22.79 % crude protein, 3.59 % ether extract, 15.49 % crude fibre, 19.46% total ash, 38.67 % NFE, 1.93% calcium and 0.26% phosphorus.
