Research was conducted to evaluate the protein quality of two varieties of sorghum (Sorghum halipensis Pers.) — common sorghum and a high lysine variety — as compared with millet (Pennisetum typhoideum Rich.) and casein. Data on food consumption, nitrogen intake, body weight and protein efficiency ratio (PER) were obtained from weanling rats.
Food intake was not significantly affected by experimental diets. The nitrogen was higher only for casein.
There was a significant difference in the ability of sorghum varieties to support growth of rats, and high lysine strain was superior. No difference was found between high lysine sorghum and millet.
The PER values were higher for the diet containing high lysine sorghum as compared to that containing common sorghum. No difference was found between high lysine sorghum and millet.
Casein was superior to the other protein sources in promoting growth. PER values were also higher for the casein diet than for the other diets.
