Dry distiller’s grains + solubles (DDGS)

- Consider it as a protein source

- Can be high in sulfur, fat and phosphorus

- Must add limestone (calcium carbonate) to offset high phosphorus

- Limit dietary inclusion rate to less than or equal to 25% (DM basis) in feedlot rations

- Limit dietary inclusion rate to less than or equal to 6 lb/cow/day (DM basis)

- Approximately 88% TDN, 28% crude protein (DM basis)

Dry corn gluten feed (DCGF)

- Consider it as a protein source

- Can be high in sulfur, fat and phosphorus

- Must add limestone (calcium carbonate) to offset high phosphorus

- Limit dietary inclusion rate to less than or equal to 30% (DM basis) in feedlot rations

- Limit dietary inclusion rate to less than or equal to 7 lb/cow/day (DM basis)

- Approximately 75% TDN, 24% crude protein (DM basis)

Soybean hulls

- Consider it as an energy source for maintenance and developer diets

- High in digestible fiber, low in starch

- Limit intake of pelleted hulls to less than 1% of body weight

- Approximately 85% TDN, 12% crude protein (DM basis)

Glycerol

- Primarily an energy source

- Can be variable in purity

- Non-purified glycerol can contain fairly high levels of methanol and salts

- Consistency of refined glycerol is similar to white Karo Corn Syrup
