Dairy cows and beef cattle have different nutritional needs, especially regarding grain requirements. Dairy cows need a balanced diet of roughage and grains to support milk production, while beef cattle primarily need roughage, with grains added to promote weight gain.
Grain Requirements for Dairy Cows vs. Beef Cattle
| Feed Type | Dairy Cows | Beef Cattle |
|---|---|---|
| Roughage | Essential for digestion and milk production; includes pasture, hay, and silage. | Primary feed source, especially for brood cows; includes pasture forage, hay, corn fodder, and straw. |
| Grains | 50–80% of diet; includes wheat by-products, corn, barley, sorghum, wheat, and oats; supplements energy needs for milk production. | Used to fatten cattle; includes corn, sorghum, milo, wheat, barley, or oats; typically 2.2 to 3.0% of live weight per day. |
| Protein Supplements | Necessary to balance the ration, especially when pasture quality is poor. | Important for first-calf heifers or heavy milking cows; nonprotein nitrogen supplements like urea and biuret can supply ⅓ to ½ of protein needs. |
| Vitamins & Minerals | Critical for overall health and milk quality. | Salt, calcium, and phosphorus (limestone and steamed bone meal) are essential; vitamin A supplements are often used. |
How Do Grain Needs Differ?
Dairy Cows: Dairy cows require a substantial amount of grain to meet the energy demands of milk production. A balanced ration ensures they receive enough nutrients to maintain milk volume and composition, especially when pasture is inadequate.
Beef Cattle: Beef cattle, particularly those in feedlots, benefit from high-energy diets of grains and legumes like corn and soy to maximize growth and weight gain. Brood cows, however, are mainly sustained on pasture and roughages, with grain supplementation for specific needs.
Why Is Roughage Important for Both?
Roughage is vital for both dairy and beef cattle due to their unique digestive systems. Their four-compartment stomachs can process roughages that monogastric animals can’t. Pasture is a natural feed, and good pasture can meet many nutritional needs.
What About Supplements?
Both types of cattle benefit from supplements. Dairy cows need balanced rations to boost milk production, while beef cattle may need protein, vitamin, and mineral supplements, especially when pasture quality is lacking.
How Does Management Impact Feed?
Beef Cattle: Beef production is highly efficient due to the costs of labor, land, feed, and money. Management practices include performance testing and preventive medicine.
Dairy Cows: Good herd management for dairy cows includes cleanliness and isolating sick animals. Disease prevention is a major concern, and a balanced diet is crucial for maintaining herd health.
What are the Best Grains for Cattle?
The best grains for cattle include corn, barley, sorghum, oats, and wheat by-products. Corn is excellent for high-energy feeds, barley is good for fattening, and oats help balance the cereal mix.
