Nutrients and anti–nutrient content of sundried cassava starch extract pulp

Abstract

Cassava starch extract pulp is an important unconventional livestock feed rich in energy but rarely used as livestock feed due to anti-nutritional factor and lack of nutrient composition. Cassava starch extract pulp was detoxified by sun drying for two week due to high sun intensity and environmental temperature. Proximate and phytochemical composition, gross energy and cyanide contentof the pulp were determined using appropriate standard methods. The results of the analysis shows that the percentage moisture, crude protein, crude fibre, ether extract, ash, dry matter and gross energy of the pulp are 5.10%, 1.30%, 3.15%, 0.71%, 4.40%, 94.90% and 4328.72kcal/kg while its cyanide content were 37.58mg/kg. The results revealed that the pulp is very rich in energy. The nutritional content of the pulp were very low, however the ranges of values obtained are below the values that can adversely affected the nutritive value or cause any toxic effects in animal. Based on the results of the study, the pulp should be supplemented with other feed ingredients such as (methionine) which are the limited amino acid and those nutrients whose nutrients are very high.
