Notes:
Eighteen samples of cottonseed oil meals from different countries in Central America were analyzed for proximate composition, free and total gossypol, epsilon-amino lysine groups and lysine, methionine, and threonine content. The meals were fed to weanling rats at a 10% protein level for 8 weeks, and protein efficiency ratios were determined at 4 and 8 weeks. The results showed a significant positive correlation between epsilon-amino groups of lysine content and PER and a negative correlation between weight gain and total gossypol content as well as between residual oil content and PER, or weight gain. L-lysine supplementation alone did not improve a poor-quality meal, while exhaustive extraction of the oil did increase the PER. The possibility of heat damage to the residual oil during the process of extraction was discussed.
