Other claims from this paper (19)
- Observation Small changes in lactic acid and ethanol varied by dry matter and hybrid in corn silage.
- Association Averaged over maturity and storage, BMR corn silage had lower lignin, crude protein and neutral detergent fiber than NORM.
- Association BMR corn silage had lower acid detergent fiber than NORM averaged across maturity and storage.
- Association BMR corn silage had higher starch than NORM averaged across maturity and storage.
- Intervention effect On average, storage between days 45 and 270 did not affect NDF digestion of either corn hybrid.
- Association NDF digestion was markedly greater for BMR than NORM corn after every storage duration.
- Intervention effect Increasing harvest maturity generally did not affect NDF digestion of NORM corn.
- Intervention effect NDF digestion of NORM corn was slightly lower in more mature plants at days 270 and 360.
- Intervention effect More mature BMR corn silage had approximately five percentage units lower NDF digestion from days 45 to 360.
- Association At harvest, starch concentration of 32% DM NORM corn was 21%, lower than other treatments at 31±3%.
- Observation Starch digestibility was highest, about 80%, in 32% DM NORM corn samples at day zero.
- Observation Other corn treatments had lower day-zero starch digestibility, 65 to 68%.
- Mechanism The low starch concentration was interpreted as the probable reason for highest day-zero starch digestibility in 32% DM NORM corn.
- Intervention effect Soluble nitrogen and ammonia-nitrogen concentrations increased with corn silage storage duration.
- Mechanism Increasing soluble and ammonia nitrogen indicated that proteolytic mechanisms remained active beyond two to three months of corn silage storage.
- Intervention effect In vitro starch digestion generally increased with corn silage storage duration.
- Mechanism The storage-related increase in starch digestion was interpreted as probably resulting from proteolysis.
- Observation Many metabolic processes remain active during long-term corn silage storage despite relatively brief active fermentation.
- Recommendation The authors recommend accounting for storage-related corn silage nutritive-value changes in ration formulations.
