Ammo CURB

Ammo CURB® Mold Inhibitor

Ammo CURB® mold inhibitor is a cost-effective propionic acid-based mold inhibitor for processed feed ingredients, complete animal feeds and total mixed rations (TMR). Available in dry and liquid formulations, Ammo CURB may be added directly to complete feed, feed ingredients and TMR and helps maintain stability of complete feeds during relatively short-term storage.

The issue of mold and mycotoxin contamination of grain and feed ingredients has existed since grain was first cultivated. Modern production practices and increased acreage appear to be contributing to an increase of the problem.1 Mycotoxins, performance-robbing organic residues produced by certain mold species, are very potent compounds.2 Very low doses in food and feed can cause human and animal health problems, but negative impact on animals represents the biggest economic loss.

Producers’ continuing shift from conventional tillage to reduced-till or no-till, narrower row widths, increasing plant population and growth of corn-after-corn acres all contribute to an increase in crop residue on the soil surface. Residue left in the field creates an excellent environment for mold spores to overwinter and survive.

Ammo CURB Dry vs. Competitive Dry Mold Inhibitor

The use of a mold inhibitor in livestock feeds is an important management tool for producers and feed manufacturers to reduce feed spoilage when environmental conditions promote microbial growth. Microbial growth can result in the heating of livestock feeds, which can lead to a decrease in palatability and feed intake as well as a reduction in the nutritive profile of the feed.3

Ammo CURB Dry vs. Ammo CURB Liquid In 2005, CO2 (carbon dioxide) studies were conducted to determine the efficacy of Ammo CURB Dry against acompetitive dry mold inhibitor, in controlling microbial growth in complete animal feed. CO2 is a product of microbial respiration and is indicative of mold growth. As mentioned earlier, mold growth can reduce the nutritive quality of feed.

The experimental conditions were controlled so that relative differences in product performance could be determined. However, the elapsed time was not exactly the same as experienced in real-time stability due to varying conditions.

At each treatment level, Ammo CURB Dry outperformed the competitive dry product in the inhibition of microbial growth. The CO2 evolution data indicates Ammo CURB Dry mold inhibitor to be twice as efficacious as the competitive product.

Ammo CURB Dry vs. Calcium Propionate4

CO2 studies were conducted again in 2005 to compare the efficacy of Ammo CURB Dry (AC) against calcium propionate in controlling microbial spoilage in a complete animal feed.

Ammo CURB Dry vs. Calcium Propionate

Figure 2. Average CO2 production over time.

At each treatment level, Ammo CURB Dry outperformed calcium propionate in the inhibition of microbial growth. The CO2 evolution data indicates the lowest application rate of Ammo CURB Dry to be more efficacious than the highest application rate of calcium propionate.
