Proximate and mineral analyses of sorghum grain treated with ethanolic leaf extracts of Euphorbia balsamifera Aiton, Lawsonia inermis L., Mitracarpus hirtus (L.) DC and Senna obtusifolia L were determined before and after being infested by S. zeamais. Twenty grams of sorghum were treated with the aforementioned botanicals at the concentrations of 25, 50 and 100mg/g. The results showed that moisture content was not significantly different (p > 0.05). Ash was higher in treated grains than in untreated ones and vice versa for crude fibre. Per cent crude lipid in treated grains ranged from 6.50 ± 0.00 to 7.17 ± 0.17% and increased with increased in concentrations. The amount of crude protein decreased drastically in untreated samples compared to treated grains where it varied between 8.75 ± 0.01 to 8.99 ± 0.41%. Carbohydrate content in the sorghum grains was significantly different (p < 0>S. zeamais on the nutritional value of sorghum grains with E. balsamifera as the most effective.
