Simple 2-part cow rations for this winter

Depending on your farm set-up, available equipment, and your willingness to purchase diesel fuel, your least-cost ration may look very different than your neighbors. Availability and proximity to co-product feeds, such as corn gluten feed (CGF) and dried distillers grains (DGS) may also shift your diet make-up.

The traditional method of winter feeding is hay. Hay is variable in quality. If hay is not sufficient in protein, energy, and other nutrients, then cows may be malnourished. This may occur even though cows have all they can eat. Poor quality forage and crop residues have a high proportion of fiber to protein, thus slowing digestion. Consequently, cows can eat only 1.5% of their body weight (BW) per day of low-quality forage. If the forage is of high quality, cows can consume around 3% of their BW daily. Poor quality hay likely needs to be supplemented to meet cow requirements

With supplementation, cows can actually digest more low-quality forage, up to 2% of their BW. Grain supplementation should be no more than 0.5 % of the cow's BW. If the forage is of such poor quality that more supplementation is required, you should consider using co-products to avoid negative associative effects that occur when using grains.

The most economical way to feed cows is to keep them grazing. Brassicas and small grains with cornstalks can be used to provide fall and winter grazing very economically. If the cattle need to be fed due to snow cover or other factors related to your farm, you should develop a low-cost method of feeding the cows.

If your cows are thin or heavy milking, you will need higher energy diets than the examples. If your cows are larger than the example, they will need proportionally more feed.
