The objective of this study is to determine the nutritive values and quality of different types of corn-based feed analysed by the Animal Feed Laboratory of the Malaysia Veterinary Institute from year 2012 to 2018. A total of 460 corn samples were received for routine quality analysis. The samples were analysed according to four categories: corn silage (126), fresh corn (176), ground corn (124) and coarse ground corn (34). Proximate analysis was carried out using AOAC method. The result for corn silage showed dry matter content of 33.11% (8.7- 99.9), crude protein 10.25% (4.1-16.6), crude fibre 26.66% (4.4-46.6) and metabolisable energy of 9.09 MJ/kg (5.6-10.89). Dry matter content of fresh corn (whole plant) was 44.75% (14.8-71.2), crude protein 8.82 % (6.7-17.3), crude fat 2.51% (1.1-4.4) crude fibre 18.61% (7.1- 41.7), total ash 4.23% (1.2- 23.) and metabolisable energy 11.60 MJ/kg (6.31-15.17). Ground corn showed dry matter content of 90.26% (84.9-97.4), crude protein 9.49% (7-13), crude fat 3.50% (0.4-10.8), crude fibre 4.03% (1.7- 21.8), total ash 2.24% (0.4- 9.5) and metabolisable energy 11.64 MJ/ kg (6.57-16.64). The proximate composition of coarse ground corn shows dry matter content of 89.98% (87.1- 95.8), crude protein 9.42% (7.4-12.1), crude fat 2.76% (1.0-6.4), crude fibre 3.34% (1.4-7.7), total ash 1.96% (0.7-5.0) and metabolisable energy of 11.77 MJ/kg (9.66-13.8). The results showed that there was a high variability in the nutrient content for corn silage, fresh corn, ground corn and coarse ground corn.
