Evaluation of Chemical Composition of Cluster Bean (Cyamopsis tetragonoloba L.) Meal as an Alternative to Soybean Meal

Abstract

The aim of this study was to evaluate the nutritional value of cluster bean (Cyamopsis tetragonoloba; guar) meal with particular emphasis on the fiber fractions, macro-and micro-elements, and anti-nutrients, as an alternative source of animal feed compared to the popular genetically modified soybean meal. The research material consisted of three types of guar meal (GM) namely, raw guar meal (GMR), roasted guar meal (GMT) and extracted guar meal (GME) purchased in India and soybean meal (SBM) produced from genetically modified soya beans. The samples were analyzed for the levels of fiber fractions, minerals and anti-nutrients. The extracted guar meal (GME) proved to be the richest source of Ca, Ptotala, Pvailable Na, Mn, Cr, Mn, Mo and Ni. In addition, it contained the lowest amount of NO3 (196.4 mg/kg DM) and anti-nutrients, compared to the other two guar meals and the soybean meal. The results of the study indicate that guar meal (especially GME) can be an attractive source of nutrients for animals, as an alternative or complement to the popular food industry by-products used in animal feeding.
