Evaluation of nutrient and anti-nutritional factors of leaves of moringa (Moringa oleifera) in Sokoto, Nigeria

Abstract

This study was conducted to evaluate the nutrient and anti-nutritional compound in moringa oleifera lam leaves affected by location. The leaves were sourced from upland, lowland, and residential gardens. The DM varies with location ranging from 96.8-91.8%. The CP differs with location ranging from 14.6-8.2%. The treatment sourced from the residential garden has the highest DM (98.6%) and the one at the lowland has the lowest (91.8%). The CP of the treatment sourced from lowland has the highest (14.6%), and that of upland has the lowest CP (8.2%). The CF of the treatment from upland is the highest (7.8%), While that of the residential garden is the lowest (4.6%). The EE has a very low amount of EE which was recorded in all the treatment in residential garden between 0.83 to 0.00%. The treatment in NFE from upland has the highest (65.7%), while that of lowland is (61.3%). The highest content of ash was recorded in the treatment from residential garden (14.2%), while that of upland is the lowest (9.8%). From the antinutritional compound evaluated, Tannin has the highest value which varies between 14.8-13.9g/100g. Saponin varies between 2.48-2.08g/100g. Alkaloid varies between 2.09-30g/100g. Oxalate varies between 1.38-1.16g/100g, Phenol varies between 0.85-0.74g/100g. From this chemical analysis, it was discovered that both samples contain a high content of starch with a good amount of CP and ash content. From the research, it shows that moringa oleifera is a good source of nutrients and therefore, moringa oleifera could be used as feed supplement for poultry lives stock production. And also the anti-nutritional analysis has also revealed that moringa oleifera is very high in Tannin but low in phenol.
