Abstract

A study on cultivation of azolla was conducted in University Research Farm, Tamilnadu Veterinary and Animal Sciences University (TANUVAS) to use azolla as a feed supplement to livestock and poultry and as a biofertilizer. Three dung materials such as dung of cow, pig and goat were utilized separately to make a slurry in cultivation of azolla for this comparative study. Among these, the highest yield of 27 kg of azolla production on 15th day of inoculation in pig dung pit followed by cow dung pit ( 25 kg) and goat dung pit (9 kg) was observed. Results of proximate analysis of three different azolla samples showed that the azolla which was produced from pig dung has the highest crude protein content (33.09%) than the other two azolla samples, whereas nitrogen free extract of azolla samples using pig dung, cow dung and goat dung are 37.34 %, 39.65% and 43.66% respectively.
