crude protein, feed value, maize cultivars, relative feed value.
Objectives of the present study were to determine the variations in grain feed quality of different hybrid maize cultivars. Experiments were conducted in randomized complete block design with 3 replications during the cropping year of 2014 under conditions of Bingol province of Turkey. A total of 25 hybrid maize cultivars were used as the plant material of the experiments. Crude protein, crude ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), dry matter digestibility (DMD), dry matter intake (DMI) and relative feed value (RFV) were investigated. The cultivars had significant effects on the grain feed quality (P≤0.01). Present finding revealed that that crude protein ratios of the hybrid maize cultivars varied between 6.80% and 11.61%, crude ash ratios between 0.30% and 2.85%, ADF ratios between 3.62% and 5.24%, NDF ratios between 11.52% and 19.74%, DMD ratios between 84.82% and 86.08%, DMI ratios between 6.08% and 10.51% and RFV between 401.19 and 698.93 depending on the cultivars. Dian maize cultivar was found to be prominent with crude protein and Eldora maize cultivar was found to be prominent with relative feed value.
