Other claims from this paper (14)
- Intervention effect Urea increased fiber components versus unfertilized forage.
- Intervention effect Dairy slurry increased fiber components versus unfertilized forage.
- Association Fiber concentration rose linearly with urea rate.
- Intervention effect Water-soluble carbohydrates declined with urea to 13.5% at 80 kg N/ha, from 21.2% unfertilized.
- Intervention effect Nonfiber carbohydrate concentration fell from 34.8% to 24.6% at 80 kg N/ha.
- Intervention effect Urea linearly increased crude protein and three soluble or insoluble protein fractions.
- Association Protein partitioning by fiber fraction was unrelated to N fertilization on a percentage of CP basis.
- Association Total digestible nutrients decreased with N rate in 2013.
- Association Total digestible nutrients decreased with N rate in 2014.
- Intervention effect Dairy slurry reduced in vitro dry matter disappearance versus unfertilized forage.
- Association Dry matter disappearance declined linearly with urea rate.
- Observation Neutral detergent fiber disappearance did not show the same response.
- Intervention effect Overall forage nutritive value declined mildly with N fertilization.
- Observation The authors judge the nutritive losses insufficient to offset yield gains.
