Silage Corn

Plant Height:

 VT = Very Tall; T = Tall; MT = Medium-Tall; M = Medium; MS = Medium-Short; S = Short

Kernel Texture:

SS = Soft; MS = Moderately Soft; M = Medium; MH = Moderately Hard

Ear Type:  

F = Flex; SF = Semi-Flex; SD = Semi-Determinant; D = Determinant

NFC Rating:  

Non-fibre carbohydrates consisting of starch, sugar, pectin and fermentation acids that serve as energy sources for the animal

WP Digestibility:

Whole plant digestibility value (higher = less loss)

NDF Digestibility:

Neutral Detergent Fiber, measure of the digestibility of the fiber composed of hemicellulose, cellulose and lignin (higher rating means that a greater proportion of the NDF is available to be digested, which may lead to greater feed intake)

Dairy Type:

Measure that includes 50% of NDF digestibility value and 50% of WP digestibility value. Dairy Type value indicates global quality of the feed and feed intake.

Beef Type:  

Measure that includes 50% of NFC Rating and 50% of WP digestibility value. Beef Type value indicates the energy content and digestibility of the feed.

Ratings:

1 = Poor; 9 = Excellent; R = Recommended; - = Rating not available

Herbicide Tolerance:

RR2 = glyphosate; LL = Liberty

Note:

Final plant population recommendations include assumptions that soil fertility and moisture holding capacity are sufficient to sustain the crop at recommended populations. Corn CHU ratings shown are for Eastern Canada; typically corn CHU ratings for Western Canada would be 100-150 heat units less.
