Biochemical and biological evaluation of different types of proteins

ABSTRACT

Seventy weaning male albino rats sprague dawely strain 28 day old weighing 35-45 gm were divided into 5 groups. Four groups of rats were provided with experimental diet representing Fish, meat, soybean concentrate and fava bean. The control group was fed casein. Results showed P.E.R. and F.E.R. were higher in the rat groups fed animal protein than plant protein. True digestibility, and N.P.U. were significantly [p < 0.01] higher in control group, meat protein and soybean concentrate than other types of proteins. While B.V was higher in casein and fish protein groups. On the other hand fish protein has a higher amino acid score and Net protein value [significant at < 0.01]
