Abstract
The relative nutritive value of male sterile corn silage (23.7% dry matter) and regular corn silage (26.5% dry matter) was determined with lactating dairy cows during three consecutive crop years. The regular corn hybrid had 25% of the kernels removed by black birds prior to harvesting. Grain was fed according to milk production (1 kg/2.75 kg milk) and silage was offered ad libitum as the only forage. Dry matter, soluble carbohydrate and insoluble nitrogen percentages were lower while crude protein and acid detergent fiber levels were higher in the male sterile corn silage. Apparent digestibilities of dry matter, nitrogen and energy determined with sheep were not different between silages. Silage dry matter intake and total dry matter intake were higher (P < 0.05) for cows fed regular corn silage in only one of the three trials. Actual milk, 4% fat-corrected milk yields and milk fat and protein percentages were not affected by silage treatment. Key words: Male sterile corn, silage, dairy cows
