A field study was carried out during 2010-11 to quantify fodder and yield qualityin three sorghum [Sorghum bicolor (L.) Moench] cultivars viz., JS-2002, Chakwal Sorghum and Local Cultivar at different growth stages i.e. 3^rd leaf stage (GS₁), prebooting (GS₂) and 50% heading (GS₃). Experiment was laid out in randomized complete block design with three replications. Cultivar JS-2002 showed the maximum plant height (196.1 cm), number of leaves per plant (11.3), leaf area per plant (535.9 cm²), stem thickness (1.7 cm), green fodder yield (63.3 t ha^-1) and dry matter yield (18.9 t ha^-1) followed by Chakwal Sorghum and Local Cultivar. Cell wall components viz., acid detergent fiber (ADF), neutral detergent fiber (NDF), hemicellulose, cellulose and silica contents were higher (72.90%, 41.91%, 34.3%, 27.77% and 3.5) in local cultivar i than rest of two cultivars. Higher contents of cell wall components indicated the inferior quality and poor digestibility of the fodder. Overall, JS-2002 sorghum cultivar provides better yield and quality among the tested cultivars. Although at GS_3, maximum fodder yield was observed but at this stage nutritional value decreased. So, GS₂ is good stage for feeding to livestock with higher nutritional value and digestibility.
