As a follow up to last week’s post, here is another question about MILK2006.
Question:
In MILK2006, with all variables held constant, what has the largest impact on milk/ton values: DM percent, NDFD percent or starch percent?
Answer:
The impact of DM%, NDFD% and starch % on MILK2006 milk/ton values are not similar across DM and NDFD levels. It appears that the starch % is the driver in digestible neutral detergent fiber. If the corn silage is even slightly immature with a low DM % (<30%), higher fiber and lower starch will be observed, suggesting a lower energy corn silage. Unfortunately starch is the main driver in MILK2006 as it relates to milk/ton, but this production prediction is not often observed in cow performance.
