The contribution of cereal protein (gluten, limited in lysine) to total protein intake varies between countries and individuals and the effect of such a variation on weight gain is not clear. Thus, the objective of this study was to determine the effect of altering protein quality, achieved by varying the casein to gluten ratio of the diet, on the feed efficiency of rats. For this purpose, male Sprague-Dawley rats were randomly divided into five groups based on the casein and gluten content of the diet that constituted the sole protein sources and covered 20percent of the total energy needs. Food intake and body weight were monitored every two days for a period of six weeks. The results showed that the high gluten groups had the lowest body weight, weight gain, food intake and feed efficiency. During the experimental period both food intake per 100g body weight and feed efficiency of the pure gluten group were constant, whereas that of the other groups decreased with time. It can be concluded that under status of sufficient percentage of energy being provided from protein using two sources that more than 25percent of protein from gluten would be needed for adequate growth. In addition, results indicate that the adoption of a cereal-based diet, particularly during the growth period may require higher levels of energy intake (due to reduced feed efficiency) or even lysine supplementation.
