AIM The present study was conducted to evaluate the effect of partial supplementation of sun-dried Azolla as a protein source on the immunity of commercial broilers in coastal Odisha. MATERIALS AND METHODS A 180 day-old broiler chicks were distributed in six dietary treatments viz. C1: Basal diet, C2: Basal diet + enzyme, T1: Basal diet +5% protein from Azolla, T2: Basal diet + 5% protein fro...

Using Azolla filiculoides , a candidate macrophyte species for ecological intensification, in small-scale aquaculture requires the investigation of potential effects fresh plant material not only on fish growth but also physiological status and responses to disease stress. In this study, juveniles giant gourami Osphronemus goramy reared into cages placed an outdoor pond were fed six weeks with ...

One hundred and twenty day old straight run coloured chicken (Chabro) were distributed into four treatments: T1-basal diet, T25% of basal diet replaced with Azolla meal on dry matter basis, T3Basal diet+Raw azolla after 4 weeks, T4T2+Raw azolla after 4 weeks. Average weekly weight gain of T1, T2 and T3 were significantly higher (P<0.01) than T4 birds at 2nd week. There was no significant differ...

The cyanobacterial symbionts in the fern Azolla have generally been ascribed to either the Anabaena or Nostoc genera. By using comparisons of the sequences of the phycocyanin intergenic spacer and a fragment of the 16S rRNA, we found that the cyanobiont from an Azolla belongs to neither of these genera.

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

Nitrogen is essential for both vegetative and generative stages of plant growth. Nitrogen efficiency is related to plant growth, production cost, and fertilizer residue. Azolla has the ability to increase nitrogen fixation from the atmosphere. Thus, Azolla cultivation in paddy field is one strategy for improving nitrogen fertilizer efficiency and increasing plant vegetative and generative growt...
