Key Benefits of Pioneer® Brand 1189 High-Moisture Corn Inoculant

Pioneer® brand 1189 high-moisture corn inoculant is available as a water-soluble product in packaging suitable for use in tank mixes or with the Pioneer Appli-Pro® systems. It is also available as a free-flowing granular formulation for easy and convenient application.

Improved Fermentation, Nutrient Retention and Digestibility

Pioneer® brand 1189 high-moisture corn inoculant is designed to help improve fermentation, retain nutrient content and enhance the digestibility of ensiled high-moisture corn.

Improved Animal Performance

Pioneer® brand 1189 high-moisture corn inoculant contains a unique blend of patented and/or proprietary strains of Lactobacillus plantarum and Enterococcus faecium formulated to help improve animal performance compared with a control group. It also helps corn ferment faster to retain more energy, and help the animal gain more energy on the same amount of feed, which indicates improved digestibility.

Higher Daily Gain and Better Feed Efficiency

Pioneer® brand 1189 high-moisture corn inoculant has shown a higher average daily gain and better feed efficiency in beef trials while also increasing dry matter recovery.

* Rapid React® aerobic stability technology       

Improved aerobic stability and reduced heating is relative to untreated silage. Actual results may vary. The effect of any silage inoculant is dependent upon management at harvest, storage and feedout. Factors such as moisture, maturity, chop length and compaction will determine inoculant efficacy.

IMPORTANT: Information and ratings are based on relative comparisons with other Pioneer® brand forage additives within each specific crop, not competitive products. Information and ratings are assigned by Pioneer Forage Additive Research, based on average performance across area of use under normal conditions, over a wide range of both environment and management conditions, and may not predict future results. Product responses are variable and subject to any number of environmental and management conditions. Please use this information as only part of your product positioning decision. Refer to www.pioneer.com/products or contact a Pioneer sales professional for the latest and most complete listing of traits and scores for each Pioneer brand product and for product placement and management suggestions specific to your operation and local conditions.

Fermentation — Rate and extent of pH decline and the composition of fermentation acids occurring in silage.

Nutrient Conservation — Retaining more sugar/starch and reducing protein degradation by rapidly reducing silage pH.

Fiber Digestibility — The digestibility of neutral detergent fiber (NDF) by the ruminant animal expressed as a percentage of the total NDF.

Bunklife — Relative heat development compared to ambient temperature. Bunklife considers both how quickly silage begins to heat and the amount of heat generated while remaining above ambient temperature.
