Abstract

In rat feeding experiments with three sorghums, protein quality index, based on protein efficiency ratio (PER) and net protein retention (NPR) at an 8.5% protein level, was found to be highest in the hybrid CSH1, followed by CSH2 and the older variety Swarna. Swarna was deficient in many essential aminoacids compared to CSH1 and CSH2. In Swarna, lysine, valine, threonine and isoleucine were most limiting while lysine and threonine were most limiting in CSH1 and CSH2. The ratio of leucine to isoleucine was much the highest in Swarna. The ratios of essential to nonessential aminoacids, to protein and to total aminoacids were higher for CSH1 than for the other varieties
