Chemical Composition and the Feeding Value of Azolla (Azolla pinnata) Meal for Egg-Type Chicks
Biochemical and nutritional studies were carried out to evaluate the potential of Azolla (Azolla pinnata R. Brown) meal, AZM, as a feed resource in the diet of egg-type chicks. In a completely randomized design, 30 two weeks old Nera brown chicks were assigned to each of the four dietary treatments containing 0, 5, 10 and 15% azolla meal. Chemical analysis indicated that azolla meal contained (...
متن کاملA preliminary examination of the phytochemical profile of Azolla microphylla with respect to Seasons
Azolla is an aquatic pteridophyte widely distributed in the water bodies. It has been traditionally used as a biofertilizer for rice paddy fields owing to its potential to fix atmospheric nitrogen [1]. In addition to this it has several other uses and Wagner [2] referred it as “green gold mine”. The plant system has the inherent capacity to synthesize several biologically active constituents wh...
متن کاملAntimicrobial activity and identification of potential antimicrobial compounds from aquatic pteridophyte, Azolla microphylla Kaulf.
Azolla microphylla Kaulf. is an aquatic nitrogen fixing pteridophyte commonly found in aquatic habitats including paddy fields. Methanolic extract of the fronds of A. microphylla was subjected to partial purification by solvent partitioning with diethyl ether and ethyl acetate followed by hydrolysis, and further partitioning with ethyl acetate. The two fractions, thus obtained were tested for a...
متن کاملAltered nitrogenous pools induced by the azolla-anabaena azolla symbiosis.
The free amino acid and ammonia pools of Azolla caroliniana were analyzed by quantitative column chromatography on columns capable of separating all of the nitrogenous constituents normally found in physiological fluids. Comparisons were made of plants containing symbiotic algae and grown on nitrogen-free media, plants grown on media containing nitrate, and algae-free plants also grown on nitra...
متن کاملPerformance of Azolla caroliniana Willd. and Salvinia auriculata Aubl. on fish farming effluent.
The increasing release of untreated fish farming effluents into water courses that flow to the Pantanal wetlands in Mato Grosso (Brazil) may drive this ecosystem to eutrophication. Therefore, the growth of Azolla caroliniana Willd. and Salvinia auriculata Aubl. in fish farming effluent and their effect on its quality were evaluated for 48 days in a greenhouse. The results were compared to those...
