 Bioethanol production can have both positive and negative impacts on cattle, depending on the context:

Positive impacts

Feed: The ethanol industry produces co-products that can be used as animal feed. For example, wet distillers' grain, a by-product of fermenting cereal grains, can be blended into animal feed. 

Land use: Using co-products from grains and oilseeds instead of grains and oilseeds themselves can reduce the amount of land needed for feedstock cultivation. 

Environmental: Bioethanol is a renewable fuel that can help conserve fossil fuels. 

Negative impacts

Land prices: The bioethanol industry can affect land prices. 

Forest clearing: The bioethanol industry may clear native forests. 

Other factors that can affect the relationship between bioethanol production and cattle include:

Integration

Co-locating a feedlot with an ethanol plant can increase the profitability of the ethanol plant. 

Manure

Using cattle manure as a raw material for bioethanol production can reduce the impact of

 manure disposal.
