Chemical analysis and biological test had been done to evaluate new variety
(Kawmi-1) of mungbean seeds (Vigna radiata) as an alternative protein source in
poultry diets. The chemical analysis included nutrients composition and essential
amino acids content. Chemical score (CS) and essential amino acids index (EMI)
values were calculated from the amino acids pattern. Total protein efficiency (TPE)
determination was carried out as a biological method to evaluate protein quality. The results of proximate analysis recorded values of: 9.53 % Moisture, 25%
CP, 1.53% EE, 3.01 % CF, 3.06% Ash, 0.14% Ca, 0.59% P and 57.87% NFE.
Mungbean seeds (MBS) protein appeared to have balanced essential amino acids
pattern. The chemical score values indicated that the first limiting amino acid was
methionine+cystine. EMI for MBS protein recorded 64.3 calculated based on whole
egg protein. TPE value for MBS was improved significantly (p < 0.05) by adding
complementary level of methionine to achieve SBM with no significant difference (2.28
vs. 2.29 for "MBS+methionine" and SBM treatments, respectively). It could be
concluded that MBS is a promising poultry feedstuff as alternative source of protein.
