Technical Abstract: Cottonseed is composed of ~22.5% of a high quality protein. This represents 3.5 MMT of protein that could be available for human consumption. Cottonseed protein currently is underutilized because of the presence of a toxic compound called gossypol. Gossypol is biosynthesized by the free radical coupling of two molecules of hemigossypol. During this coupling reaction, two optically active enantiomers are formed. One of these is referred to as (+)-gossypol and the other as (-)-gossypol. The enantiomers exhibit different toxicity to non-ruminant animals. Uzbekistan breeders have developed cotton lines containing 93%(+)-gossypol. Cottonseed derived from these lines were fed to broilers. Our research has shown: - The lines with a high percentage of (+)-gossypol in seeds possess good agricultural properties including fiber quality, and are suitable for cultivation in Uzbekistan; - When tissues of chickens first fed cottonseed meal were analyzed for gossypol, residual gossypol in these tissues was removed after feeding a control diet for 2 weeks; - The meal received from cotton seeds containing 93% (+)-gossypol can be used as diet for broilers. Thus, cottonseed containing a high level of (+)-gossypol can be included in the diet of broilers.
