Abstract
The study was carried out to compare the yield and nutritive value of recently introduced fodder species; Sorghum var. Sugar Graze with hybrid Napier var. CO-3, commonly used fodder by Sri Lankan dairy farmers. Field experiment was conducted as a Randomized Complete Block Design. Two harvests were obtained at 50% flowering stage and yield parameters, nutritive and anti-nutritive factors were determined. Plant height and dry matter yields of Sugar Graze were significantly (P < 0.05) higher compared to CO-3 in both harvests. However, the highest soluble carbohydrate contents was recorded for Sugar Graze in 2nd harvest. Oxalate contents were significantly lower (P < 0.05) in Sugar Graze compared to CO-3 in both harvests. Sorghum var. Sugar Graze could be effectively utilized to increase nutritional status of dairy cows in Sri Lanka.
