Abstract
The nutritional -.alue of proteins dependJ upon the 8lllounts
of essential amino acids and their existence in a suitable
form. Poultry relatively need high amounts ot protein U1
their diets to meet their fast gro~h and egg production ~
Therefore, the dietary protein has to be chosen carefully especially
tortts• biological value and priee.
In developing couatries, as in Egypt, since the animal
dietary protein is not sufficient and expensive, the plant
dietary protein is usually used as the major source in daily
diets for human and animals. Therefore, it is important to
study our local plant proteins and to what extent could be
used, by finding out some wa:ys to enhance their nutritional
value. This could help us in solVing the shortage o’f animal
protein in poultry diets •
T.he ma~ority of plant proteins suffer either deficiencies
of one or more of the essential amino acids or imbalance
of their amino acids content • On the other hand, their poor
protein digestibility due to the presence of some growth inhibiters,
usually limits their utilization •
It is eommon practice in Egypt that field beans Vicia
tatia (V.F.) are used in cqmpound diets as a source of dietar,y
protein in poultry feeding.
