Description The low nutritive value of vegetable proteins as compared to animal proteins is
attributable to imperfection in the amino acid make-up of the vegetable protein and may
be corrected by proper fortification of the protein with the limiting amino acids. Increasing
the level of low quality vegetable protein in the diet may lead to a level at which
the growth response obtained is equal to that obtained with the animal protein diet at a lower
level. It has been reported that peanut protein is equal to casein in promoting growth
of rats when fed at 20 per cent level1'2. Consequent on the higher intake of low quality
protein, certain other changes may occur. It has been observed that with higher intakes
of protein, there is a decrease in protein efficiency ratio which has been attributed to a
greater waste in metabolism3. Stanier4 noted that when rats were fed a high protein diet
in such a way that their body weight ran parallel to that of animals on a low protein diet,
certain changes in body composition were caused.
A preliminary experiment was, therefore, designed to ascertain the level at which a low
quality protein, such as wheat gluten, would give the same growth response as given by a
high quality protein, such as casein and to study the effect of these proteins on body
composition.
