Abstract
The effects of a chemical drying agent on in situ rate and extent of disappearance of DM, NDF, and ADF of alfalfa were investigated. Two field replicates of first-and second-cutting alfalfa (early bloom) were treated at harvest with a potassium carbonate-sodium carbonate based chemical drying agent (7.9 kg/ha). Samples were separated into leaf, stem, and whole plant fractions and artificially dried. Treatments were arranged as a 2 x 2 x 3 factorial and analyzed as a completely randomized block design. Treatment had a greater effect on initial nutrient composition, compared with untreated, for all fractions in second cutting alfalfa. In situ OM disappearance was not affected by treatment in the first cutting for any fraction. In first-cutting leaves, NDF and ADF in situ disappearance was increased by treatment. Rate of OM and ADF disappearance for treated second cutting leaves and stems decreased compared with untreated samples. Lag time associated with NDF disappearance increased in second-cutting leaves and stems treated with drying agent. Potentially digestible ADF and lag time increased in second-cutting stem, and lag time for the whole plant decreased. Dry- ing agent application had different effects on nutrient composition and digestibility of first and second cuttings and on leaf and stem fractions of alfalfa.
