This study investigates the technological features and efficiency of harvesting pressed sorghum feed, focusing on optimizing yield, nutritional retention, and economic viability. Field trials were conducted across three agricultural zones with varying sorghum cultivars (Sorghum bicolor L.), analyzing mechanized harvesting systems, pressing techniques, and post-processing outcomes. Results demonstrated that employing a combined rotary cutter and hydraulic press system increased pressed feed yield by 22% compared to traditional methods, achieving an average output of 8.5 tons ha-1 with moisture content stabilized at 14–16%. Nutritional analysis revealed that pressed sorghum retained 88–92% of crude protein (10.2–12.6% dry matter basis) and 78% of digestible fiber, outperforming loose-stalk storage by 15–20%. Mechanized harvesting reduced labor costs by 30% and operational time by 40%, while energy consumption averaged 18.5 kWh ton-1, a 15% reduction over conventional systems. Regional trials highlighted cultivar-specific performance, with hybrid SPV-2316 achieving the highest pressing efficiency (94%) under mechanized conditions. Storage trials indicated a 12% reduction in spoilage rates for pressed bales compared to chopped forage, attributed to compact density (650–700 kg m-³) and reduced oxidative exposure. These findings underscore the potential of advanced harvesting technologies to enhance sorghum feed productivity, reduce waste, and support sustainable livestock nutrition.
