FRESH CUT® Plus Liquid is a hay preservative for hay baled at higher moisture levels. FRESH CUT Plus is an organic acid blend effective against a wide variety of mold strains and buffered to protect equipment from corrosion. The liquid formulation allows for more complete distribution and penetration into hay.
Harvest and storage losses for baled hay can represent a significant source of economic loss. These losses are directly related to the length of time cut hay lays in the field prior to baling. Baling hay at higher moisture levels reduces leaf shatter and field curing time. Additionally, more protein-rich leaves and softer stems improve digestibility. In order to bale at moisture levels above 15 percent, forage quality solutions are required to inhibit microbial growth and deterioration of the hay during storage.
FRESH CUT Plus contains a blend of organic acids, a powerful surfactant and acids effective against mold and wild yeast growth. FRESH CUT Plus is buffered to reduce metal corrosion while improving worker safety. The liquid formulation allows for more complete distribution, dispersion and penetration into hay.
Kemin conducted a trial in Nebraska to show the benefits of treating 24 percent moisture hay with FRESH CUT Plus.1 Both crude protein (CP) digestibility and neutral detergent fiber (NDF) digestibility were improved in hay treated with FRESH CUT Plus.

In the Nebraska hay trial, hay treated with FRESH CUT Plus was not only more nutritious, but the hay was visually more appealing. Using a scale from 1-5, where one was excessively dry and five was excessively heat damaged, hay treated with FRESH CUT Plus scored from 2.2-3.2.
|Visual Score 5||Visual Score 4||Visual Score 3||Visual Score 2||Visual Score 1|
|Baling Moisture: 25-27%||Baling Moisture: 21-24%||Baling Moisture: 21-24%||Baling Moisture: 15-20%||Baling Moisture: 15-20%|
|Extensive Heat Damage||Moderate Heat Damage||Low Heat Damage

|Heat Units > 350||Heat Units > 250||Heat Units ≈ 150||Heat Units ≈ 120||Heat Units < 120|
|Crude Protein: 19.5%||Crude Protein: 18.6%||Crude Protein: 20.9%||Crude Protein: 20.7%||Crude Protein: 20.9%|

As observed in the Nebraska hay trial, drying hay below 20 percent moisture reduces the incidence of heat damage. At the same time, application for FRESH CUT Plus Liquid to hay above 20 percent moisture resulted in less bale heating. In a trial conducted in Torreon, Mexico, the optimum hay was produced using a combination of dew moisture and FRESH CUT Plus.

In a trial conducted in the San Joaquin Valley of California, the producer recovered more dry matter per bale when bales were treated with FRESH CUT Plus. Given the baler settings during this trial, baling at higher moisture and applying FRESH CUT Plus at recommended rates would recover approximately 19 percent more alfalfa dry matter (DM) per acre from a field.

At the same time, when applied at recommended rates, FRESH CUT Plus lowered mold (P < 0.01) and wild yeast (P < 0.05) counts in cured alfalfa hay compared to the control. Blended organic acid products such as FRESH CUT Plus should be effective in reducing the growth of molds and wild yeast over time, which was supported by the trial results.

FRESH CUT Plus application at recommended rates lowered mold (P < 0.01) and wild yeast (P < 0.05) counts in cured alfalfa hay compared to the control. Blended organic acid products such as FRESH CUT Plus are effective at reducing the growth of molds and wild yeast over time, which was supported by the trial results.
