OBSERVATIONS ON FORTIFICATION EFFECT OF CORN GERM PROTEIN ON WHEAT PROTEIN (I) YOUNG RAT GROWTH,NITROGEN BALANCE AND APPARENT NET PROTEIN UTILIZATION / 营养学报

ABSTRACT

The corn germ protein tested was a by-product from, corn starch plant and it contained more lysine (average 5.7%) and a relatively ideal proportion of eight essential amino acids similar to the 1973 FAO/WHO provisional amino acid pattern. A 5-week rat growth experiment was conducted to evaluate the nutritive value of corn germ protein by using body weight gain, nitrogen balance and apparent net protein utilization as assessment criteria.The feed of the experimental group was made of wheat protein supplemented with 17.3% germ protein and that of the control with 2.4% wheat glu- ten to made the final protein level of both feeds equivalent to 10%.These results showed that the body weight gain of rat in the experimental group was higher than that of the control group regardless of female or male, the body weight gain per 100g feed consumed in two groups of female was 19.0g and 12.2g and that of male was 17.6g and 10.4g respectively (p
