Harvest and storage losses for hay and silage can represent a significant source of economic loss. After all, preserving home-grown forages reduces the cost of buying extra feed. In addition, preservation of forage quality is the foundation of a good livestock nutrition program. Quality roughage should contain the maximum digestible energy and protein available to meet the needs of high producing livestock. Several factors can reduce an ideal forage into an average or fair forage. One of the most frustrating factors resulting in downgraded hay quality are mold and microbes (e.g., fungi and wild yeast).

Before hay and forage are harvested or baled, the addition of preservative products almost always result  in a good return to a producer's investment. Silage inoculants help economically enhance fermentation when crops are harvested with an ideal moisture concentration. Acid-based preservatives for hay, haylage or silage will reduce losses from molds, bacteria and fungi, especially when the forage is not harvested at the ideal moisture levels. Excessive microbial growth can cause hay bale heating, increasing dry matter loss and producing Maillard reactions, which reduce dry matter and crude protein digestibility. To combat these issues, Kemin has worked to create several effective preservatives for high moisture forage such as,  organic acid preservatives for hay and inoculants and organic acid blends to inhibit microbial growth in silage.

Preservatives for High Moisture Forage

Baling hay at higher moisture levels reduces leaf loss and field curing time. By retaining the protein-rich leaves, producers harvest more protein per acre. Reducing field curing time allows for earlier hay regrowth, and this regrowth is less subject to damage by equipment. Earlier baling allows quicker irrigation so the next harvest can begin sooner. However, in order to bale hay at moisture levels above 15 percent, treatments are recommended to prevent deterioration and heating during storage.

Silage SAVOR® is a unique, premium blend of organic acids formulated to enhance silage fermentation. Silage SAVOR Plus Liquid is a concentrated blend of three organic acids offering a wide spectrum of control against organisms found in all silage types. Silage SAVOR Dry is a convenient, dry product designed to assist in the fermentation of silages by providing an environment that is optimal for epiphytic lactic acid-producing bacteria to grow. The dry and liquid forms of Silage SAVOR create favorable fermentation, resulting in a rapid drop in pH to provide a stable silage. Additionally, each can be used on forage crops and high moisture corn to promote more uniform fermentation to help maintain nutrient value by reducing heating and dry matter loss. 

Inoculants for Forage Preservation

Kem LAC® HD is a water-soluble mixture of three lactic acid-producing organisms to be used in a wide variety of forages chopped for ensiling. This high-density (HD) inoculant blend provides more bacteria per gram than other products available on the market and can help speed fermentation. By producing a high level of lactic acid, the use of Kem LAC HD quickly lowers silage pH and aids in preservation of the crop. Kem LAC HD works in a wide variety of forages including corn, wheat, sorghum and alfalfa silage to help reduce dry matter loss and preserve nutrient availability. Kem LAC HD also controls silage temperatures from within the silo, while helping to reduce dry matter loss and shrinkage.
