Other claims from this paper (8)
- Observation Moisture contents of silages from corn harvested at four maturity stages were 69.9, 67.6, 64.9 and 58.0%.
- Intervention effect Dry matter intake was similar across the four corn harvest maturity treatments, at 3.73 to 3.79% of body weight.
- Intervention effect Milk production was highest (33.4 kg/d) for cows fed silage from corn harvested at the two-thirds milkline stage.
- Intervention effect Milk production was lowest (32.4 kg/d) for cows fed silage from corn harvested at the early dent stage.
- Intervention effect Milk protein production was highest for cows fed silage from corn harvested at the two-thirds milkline stage (1.17 vs. 1.12 to 1.13 kg/d).
- Intervention effect Apparent total tract digestion of acid detergent fiber and starch was lowest for cows fed silage from corn harvested at the black layer stage.
- Intervention effect Intake of digestible starch was 0.4 kg/d lower for cows fed silage from corn harvested at the black layer stage.
- Recommendation The optimum harvest stage for corn to be ensiled is two-thirds milkline, with some flexibility between quarter and two-thirds milkline.
