Beef Cattle Feed: What It Contains and How to Choose the Right Ration

By Dr Duncan Houston

“Beef cattle feed” can mean anything from pasture and hay to a formulated pellet or a mixed finishing ration. The right choice depends on the cattle you are feeding and what you need them to achieve.

A breeding cow maintaining body condition, a recently weaned calf and a steer being finished for sale have different nutritional priorities. Feeding them all the same product can waste money and leave some animals short of essential nutrients.

Quick Answer: Beef cattle diets usually combine pasture or other forage with supplements where needed. Commercial feeds commonly contain cereal grains, protein meals, fibrous by-products, molasses and minerals. Choose a feed that fills the gaps in the existing diet and supports the animal’s growth, pregnancy, lactation or maintenance requirements.

There is no single standard beef cattle feed recipe.

Many beef cattle obtain most of their nutrition from pasture. Other systems use conserved forage, supplementary grain, commercially prepared feeds or complete mixed rations.

A supplement supplies nutrients alongside the existing diet. A complete ration must provide the animal’s overall nutritional needs, including suitable roughage. A mineral lick or protein block has a much narrower role.

Check the feeding directions before buying. A product labelled “beef pellets” should not automatically be treated as a complete diet, and pelleting does not remove the risk of grain overload or inadequate effective fibre.

Common ingredients contribute different parts of the ration:

Feed component	Common examples	Main contribution
Pasture and forage crops	Grasses, legumes and suitable grazing crops	Fibre, energy and variable protein
Conserved forage	Pasture hay, lucerne hay, grass silage, maize silage	Stored feed supplying roughage and nutrients
Cereal grains	Barley, wheat, maize, oats, sorghum	Mainly starch and energy
Protein feeds	Canola meal, soybean meal, cottonseed meal, lupins, peas	Protein, with varying amounts of energy
Feed by-products	Wheat bran or pollard, distillers grains, other suitable processing by-products	Variable combinations of energy, protein and fibre
Molasses	A by-product of sugar production	Sugars and energy; also used to carry other ingredients
Mineral and vitamin supplements	Salt, calcium and phosphorus sources, trace minerals and vitamins where required	Correct specific gaps in the diet

A manufactured beef pellet may combine several of these ingredients. Its suitability depends on their proportions, nutrient availability and recommended feeding rate. The ingredient list alone does not tell you whether it will meet your cattle’s needs.

The starting point is the class of stock and the production goal:

Cattle group	Main feeding priority	What to consider
Mature dry cows	Maintain suitable body condition	Forage quantity and quality, pregnancy stage and weather
Late-pregnant and lactating cows	Support the calf, milk production and the cow’s condition	Increasing nutrient demand and whether intake can meet it
Recently weaned calves	Maintain health and steady growth through weaning	Highly digestible, palatable feed suited to age and weight
Growing cattle	Build frame and muscle towards the next production stage	Target growth rate and the nutrients limiting it
Replacement heifers	Reach appropriate joining weight and condition	Sustained growth without excessive fattening
Finishing cattle	Reach the required sale weight and fat specification	Energy intake, rumen health, time on feed and cost of gain

Younger weaners need particular attention. Their smaller intake capacity makes poor-quality forage a greater limitation, and a diet suitable for mature cows may be inadequate for them.

A practical buying decision follows these steps.

1. Define the result you need.

   Decide whether you are maintaining cattle through a feed shortage, improving breeder condition, growing weaners or finishing stock for a particular market.

   Record approximate liveweight, body condition, age, pregnancy or lactation status and the intended feeding period. For sale cattle, establish the buyer’s weight and fat requirements before choosing a finishing program.

   A feed that produces faster growth may still be poor value if cattle become overfat, miss the intended market or require more feeding days than expected.

2. Assess both the amount and quality of existing forage.

   A paddock containing plenty of standing dry grass can still provide inadequate nutrition. Conversely, good-quality pasture may meet the needs of some cattle without an additional energy or protein supplement.

   Check pasture availability and obtain representative tests for purchased hay, silage and other substantial ration ingredients. Useful results include dry matter, metabolisable energy, crude protein, fibre and digestibility.

   Test results should represent the actual feed being purchased or fed. A report from an unrelated batch is a weak basis for ration planning.

3. Identify which nutrient is limiting performance.

   When there is abundant dry forage but insufficient protein, an appropriate protein supplement can help rumen microbes digest and use that forage.

   When there is too little forage overall, a protein lick cannot make up the missing feed supply. The cattle need an adequate quantity of feed as well as the correct nutrient balance.

   If energy is limiting growth, an energy supplement may help. If a mineral deficiency is limiting performance, adding more grain may fail to address the problem. Match the supplement to the gap.

4. Read the analysis and feeding instructions together.

   Ask the supplier for the intended stock class, feeding rate, adaptation instructions and whether additional roughage is required.

   The most useful figures include dry matter, metabolisable energy, crude protein, fibre and relevant minerals. Check whether percentages are reported on an as-fed or dry matter basis.

   A higher protein percentage is not automatically better. What matters is the amount and type of protein supplied by the whole diet, together with enough usable energy. A small quantity of a concentrated supplement and a large quantity of a lower-protein feed cannot be compared by percentage alone.

5. Compare prices after accounting for moisture and quality.

   Dry matter is the portion of feed remaining after its water is removed. For example, 20 kg of silage containing 35% dry matter supplies 7 kg of dry matter.

   Using hypothetical prices:

   • Feed A costs $360 per tonne and contains 90% dry matter: $400 per tonne of dry matter.

   • Feed B costs $180 per tonne and contains 30% dry matter: $600 per tonne of dry matter.

   Feed B is cheaper by delivered weight but more expensive per unit of dry matter. You still need to compare its energy, protein and suitability for the ration.

   Include freight, storage losses, wastage and handling costs. The cheapest delivered tonne is not necessarily the cheapest useful feed.

6. For growing and finishing cattle, assess cost per kilogram gained.

   A useful calculation is:

   Feed cost per kilogram of liveweight gain = total daily feed cost per animal ÷ average daily liveweight gain.

   For illustration, a full feeding program costing $2.40 per head daily at 0.8 kg daily gain has a feed cost of $3.00 per kilogram gained. A program costing $3.00 daily at 1.2 kg gain has a feed cost of $2.50 per kilogram gained.

   These are hypothetical examples, not promised growth rates. Include the whole feed cost, including forage. Then account for other expenses and the value of the finished animal.

   When evaluating a supplement on pasture, compare its additional cost with the additional sale value it creates. Some growth would have occurred without the supplement, so attributing all weight gain to it can overstate the return.

7. Check that the feeding system can deliver the ration consistently.

   Consider storage, mixing accuracy, feeding frequency, trough access and how you will manage smaller or less dominant cattle.

   A good ration can perform poorly if some animals cannot reach it. Separating cattle by size and nutritional need can improve access, particularly around weaning.

   Introduce new concentrates progressively and use an adaptation plan suited to the product and cattle. Do not suddenly move cattle from a forage diet onto unrestricted grain or pellets.

Urea-containing feeds deserve particular care.

Urea supplies non-protein nitrogen that rumen microbes can use under suitable conditions. It does not provide energy or the same nutritional package as a plant protein meal.

It can be useful in correctly formulated supplements, especially where cattle have adequate mature forage that is low in protein. However, excessive or rapid consumption can be fatal. Follow product instructions, control intake and avoid improvised mixing or allowing supplement troughs to collect water.

Young calves need feeds appropriate to their developing digestive systems. Adult cattle licks and urea-containing supplements should not be substituted casually for calf feeds. FutureBeef specifically advises avoiding urea-containing feeds for weaners under 100 kg.

Mineral selection also depends on location and diet. Phosphorus deficiency is important in parts of northern Australia and can impair growth and reproduction even where energy and protein are adequate.

That does not mean every herd needs the same mineral mixture. Identify the likely deficiency with your adviser and assess the complete diet before adding more products.

Water availability is part of the feeding program. Insufficient or poor-quality water can restrict intake, growth and health. Requirements vary with animal size, lactation, temperature, feed moisture and access.

Check trough cleanliness, refill speed and access during peak demand, particularly in hot weather or when moving cattle onto drier feeds.

Once feeding begins, record feed use and refusals, observe appetite and cud chewing, and follow weight and body-condition trends.

Use consistent weighing procedures. Changes in gut fill and hydration can distort short-term liveweight comparisons, so one unexpectedly heavy weighing does not prove the ration is producing better tissue growth.

If cattle underperform despite apparently adequate feeding, investigate more than the feed label. Uneven access, nutritional imbalance, respiratory disease and digestive illness can all reduce growth. Persistent poor performance warrants a veterinary and nutritional assessment.

The response should match the signs:

What you notice	Appropriate action
Cattle remain bright but consistently miss growth targets	Review intake, feed tests, access and health before increasing concentrates
Cattle lose condition despite supplementation	Promptly reassess the feed budget and arrange advice
A cow stops eating, becomes dull or develops marked diarrhoea	Seek veterinary advice the same day
Severe abdominal swelling, breathing difficulty, staggering, collapse or suspected grain or urea poisoning	Seek emergency veterinary help immediately

After accidental access to a grain store or a potentially excessive amount of urea supplement, remove further access and contact your veterinarian promptly, even if obvious illness has not developed.

Common mistakes include:

• Feeding all stock classes the same ration.

• Treating a protein block as a replacement for adequate forage.

• Buying on protein percentage or price per tonne alone.

• Assuming pellets cannot cause acidosis.

• Making abrupt feed changes.

• Continuing an expensive feeding program without measuring results.

A few common questions help narrow the choice:

• Can beef cattle grow and finish on pasture alone? Yes, where pasture quantity and quality meet their requirements. Growth rate, season and market targets determine whether supplementation is worthwhile.

• Are pellets better than loose grain? Either can be useful. Compare the formulation, required supplements, handling convenience and total cost.

• Can I feed dairy pellets to beef cattle? Some may fit a beef ration, but check their intended use, ingredients, mineral supply and economics. They are not automatically the best choice.

• How many kilograms should I feed per animal? That requires liveweight, age, production goal, forage intake and the feed specification. There is no universal allowance for “beef cattle”.

• Will more grain always produce a better result? No. Benefits depend on the existing diet and the animal’s requirements, while excessive or poorly introduced grain increases health risks.

Before ordering feed, gather the product specifications, forage test results, cattle weights and your production target. Those details allow your veterinarian or beef nutrition adviser to select a ration that supports healthy cattle and a measurable return.
