The expanding ethanol industry is increasing the supply of corn milling byproducts like distillers grains and corn gluten feed. These byproducts can enhance cattle performance and profitability in feedlot diets.
Area of Science:
- Agricultural Science
- Animal Science
- Biotechnology
Background:
- The ethanol industry's growth leads to a significant increase in corn milling byproducts.
- Distillers grains and corn gluten feed are key byproducts with potential for livestock feed.
Purpose of the Study:
- To evaluate the impact of corn milling byproducts on feedlot cattle performance.
- To explore strategies for optimizing the use of these byproducts in cattle diets.
Main Methods:
- Analysis of feeding trials incorporating distillers grains and corn gluten feed.
- Assessment of cattle performance metrics (e.g., weight gain, feed efficiency).
- Evaluation of dietary adjustments in grain processing and roughage levels.
Main Results:
- Corn byproducts can improve cattle performance and profitability in feedlot rations.
- Adjusting grain processing and roughage levels can further enhance cattle performance.
- Innovative storage and dried byproduct options provide flexibility for smaller operations.
Conclusions:
- Corn milling byproducts are valuable feed resources for the cattle industry.
- Optimizing diet formulation and utilizing available byproduct forms are crucial for maximizing benefits.
- Continued evaluation of new ethanol byproducts is necessary to determine their feeding value.
