Abstract Cumbu Napier (COBN-5) fodder was evaluated for oxalate content, carbohydrate and protein fractions at different stages (30, 35, 40, 45 and 50 days) of harvest in its second cut. The per cent oxalate content was highest (3.32) in the COBN-5 fodder harvested at 30th day as compared to the mature fodder (1.64) at 50th day with the moderate content (2.31) at 40 days of harvest. High lignin (% NDF), while low NSC (% DM) and starch (% NSC) were observed in COBN-5 fodder harvested at 50 days as compared to other stages. The mean NDICP and ADICP content (% CP) were 59.82 and 16.0, respectively. The carbohydrate fractions (% CHO) revealed that carbohydrate fraction A (CA) was highest at 45 days of harvest, while fraction C (CC) was lowest at 30 days of harvest in COBN-5 fodder. Data on protein fractions (% CP) showed that protein fraction (PB2) was highest (8.34) at 50 days, while PB3 was highest at 30 days of harvest in COBN-5 fodder. It was concluded that COBN-5 fodder harvested at 40 days contains moderate oxalate content and better carbohydrate and protein fractions which reflects high nutrient intake and digestibility.
