Dough Stage

Whole crops of corn, barley, wheat, and forage oats were ensiled and fed as the sole forage to 48 milking cows in two 12-wk feeding trials. In the first experiment corn (25.1% dry matter (DM)) harvested in the early dent stage, barley (34.2% DM), and forage oats (27.6% DM) harvested in the dough stage were compared. Holstein cows fed the three silages averaged 22.6, 19.7, and 18.7 kg of 4% fat-corrected milk per day and consumed 1.67, 1.82, and 1.85 kg of silage DM per 100 kg body weight, respectively. In the second experiment, cows fed wheat (35.7% DM), barley (29.8% DM), or forage oat (27.0% DM) silage harvested in the dough stage produced 21.2, 23.3, and 22.1 kg fat-corrected milk daily and consumed 1.75, 1.71, and 1.62 kg silage DM per 100 kg body weight, respectively. Corn silage DM intake was lower (P < 0.01) but more efficiently utilized for milk production (P < 0.01) than barley or forage oats, whereas wheat, barley, and forage oat silages were similar in feeding value. In experiment I, rumen acetate increased and butyrate decreased with corresponding increases in forage fiber content. Propionate levels were unaffected by the kind of forage, whereas blood urea nitrogen was highest for cows fed forage oats in both experiments.

Vacuum silages made from Pioneer 383 and Pride 5 corn were fed with concentrate and with and without hay to lactating dairy cows. Yields per hectare in terms of dry matter were 8,850 kg for Pioneer 383 and 8,350 kg for Pride 5. Intake of silage dry matter was significantly higher (P < 0.05) for Pride 5 (11.4 kg/day) than for Pioneer 383 (9.8 kg/day), and significantly lower (P < 0.05) for both silages when hay was fed (11.4 kg/day versus 9.7 kg/day). Fat-corrected milk production was significantly higher (P < 0.05) for Pride 5 (17.0 kg/day) than for Pioneer 383 silage (15.8 kg/day), and significantly higher (P < 0.05) when hay was fed, than without hay supplementation (167 kg/day versus 16.0 kg/day). Utilization of silage dry matter in terms of fat-corrected milk production per hectare was 10,486 kg for Pride 5 corn silage and 11,176 kg for Pioneer 383 corn silage.

Corn Hybrid

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
