Meat Sheep Feed vs Dairy Sheep Feed: What Is the Difference?

By Dr Duncan Houston

Sheep raised for meat and sheep kept for milk can eat many of the same ingredients. What changes is the nutritional balance, the amount they need and how their diet is managed through growth, pregnancy and lactation.

A rapidly growing lamb, a ewe rearing twins and a dairy ewe in full milk are all demanding customers. A dry adult sheep has a very different shopping list.

Choosing suitable feed starts with the animal’s current needs and the forage available, not simply whether the flock is labelled “meat” or “dairy”.

Quick Answer

Meat sheep feeding programmes support lamb growth, suitable carcass finish and breeding performance. Dairy sheep diets support sustained milk production while maintaining body condition, fertility and rumen health. Both need balanced energy, protein, fibre, minerals and water, and young growing lambs can need protein concentrations similar to those of milking ewes. Use feed formulated for sheep and balance the entire ration for the animal’s production stage.

Why do meat sheep and dairy sheep need different diets?

For lambs raised for meat, the aim is healthy growth towards the required market weight and fat cover. Nutritional needs change as lambs move from milk feeding to weaning, growing and finishing.

For dairy ewes, nutrients must support repeated milk production as well as maintenance, pregnancy and recovery of body reserves.

However, milk production also matters in meat flocks. A ewe nursing twins or triplets may have substantial requirements even though none of her milk enters a dairy tank. Her feeding programme should reflect how many lambs she is supporting.

Dry ewes, breeding rams and older sheep being prepared for mutton need separate consideration. Their diets should match body condition and the intended outcome, rather than automatically copying a growing-lamb ration.

How do the nutritional priorities compare?

Nutritional feature	Sheep raised for meat	Dairy sheep in milk
Main production goal	Lamb growth, appropriate finish and successful breeding	Milk yield and composition, with healthy body condition
Energy	Matched to growth rate, maintenance, pregnancy or nursing demands	Matched to milk output, intake and stage of lactation
Protein	Particularly important in young, rapidly growing lambs and nursing ewes	Supports milk protein production and the ewe’s own tissues
Fibre	Supports rumen health in grazing and concentrate feeding systems	Supports rumen function and a balanced milk-production diet
Minerals	Must suit sheep, with attention to copper and male urinary health	Must suit sheep and account for pregnancy and milk production
Feeding stages	Milk-fed lamb, weaner, grower, finisher and breeding flock	Lamb rearing, replacement ewe development, dry period and lactation

There is no single “meat sheep diet” or “dairy sheep diet” suitable throughout life. Production stage often matters more than the breed label.

Compare feed on a dry matter basis

Dry matter is the part of a feed left after its water is removed. It allows useful comparisons between wet pasture, silage, hay and concentrates.

For example:

• 4 kg of silage at 30% dry matter provides 1.2 kg of dry matter.

• 1.5 kg of hay at 85% dry matter provides about 1.28 kg of dry matter.

These are calculation examples, not daily feeding recommendations. Similar amounts of dry matter can also differ greatly in digestibility and nutrient content.

Check whether a feed analysis reports results on a dry matter or as-fed basis before comparing prices or protein percentages. A cheaper tonne of wet feed is not automatically a cheaper source of usable nutrients.

Do dairy sheep always need more protein?

No. High milk production requires substantial protein, but small lambs growing quickly can also need a protein-rich diet.

For illustration, Agriculture Victoria gives these approximate requirements for weaners:

• A 15 kg lamb gaining 100 g daily: about 16% crude protein.

• A 15 kg lamb gaining 200 g daily: about 18 to 20% crude protein.

These examples show how growth targets change the required nutrient concentration. They are not universal targets for all lambs.

For dairy ewes, extension guidance suggests around 17 to 18% crude protein on a dry matter basis during early lactation to support high milk production. Requirements change with milk output, feed intake and lactation stage.

The practical lesson is to assess the animal and the whole ration. A protein percentage on a supplement bag tells you little unless you also know what pasture, hay or silage the sheep are eating.

Protein quality and energy must work together

Sheep rely on rumen microbes to digest much of their feed. Those microbes need an appropriate supply of nitrogen and fermentable energy.

The animal then receives protein from the microbes and from dietary protein that escapes rumen breakdown. Consequently, crude protein percentage alone does not describe the full feeding value of a ration.

Research in dairy ewes has shown that how dietary protein is broken down in the rumen can affect milk production and protein utilisation. This supports balancing the ration carefully rather than simply increasing its crude protein concentration.

In growing lambs, extra protein may deliver little benefit when energy intake is the main limitation. Spending more on protein does not repair an energy shortage.

How do energy and fibre requirements differ?

Growing and finishing lambs need enough energy to achieve the intended weight gain. As animals approach their target finish, feeding should account for condition and market requirements rather than pursuing weight alone.

Milking ewes need energy for milk production while maintaining their own tissues. During demanding periods, intake may fail to match requirements, leading to loss of body reserves. The diet needs to supply nutrients in a form and quantity the ewe can actually consume.

Both groups need effective fibre to support chewing, saliva production and rumen function. Too little roughage increases digestive risk, while too much poorly digestible material can prevent sheep from eating enough useful energy.

A paddock full of dry stalks may look well stocked with feed while supplying surprisingly little nutrition. Assess forage quality as well as quantity.

What are meat sheep and dairy sheep feeds made from?

Common ingredients include:

• Forages: pasture, grass hay, lucerne hay and suitable silage.

• Energy feeds: barley, oats, wheat, maize and carefully selected by-products.

• Protein ingredients: suitable pulses and oilseed meals, such as soybean or canola meal.

• Mineral and vitamin supplements: formulated specifically for sheep and the identified requirements.

The ingredients may overlap substantially between meat and dairy rations. Their proportions, quality and feeding rates determine what the complete diet supplies.

Check whether a purchased product is a complete feed, concentrate or supplement. Many pellets are intended to accompany forage and should not be treated as the entire diet.

Sheep generally do not require cereal grains to be processed in the same way as cattle. Unnecessary grain processing can increase acidosis risk, so follow a sheep-specific feeding programme.

Copper is a particularly important sheep precaution

Sheep require copper, but excessive intake can accumulate in the liver and cause serious poisoning. This makes casual sharing of cattle feeds, goat feeds or mineral mixes risky.

Choose products specifically suitable for sheep. If a product is labelled for several species, confirm that its formulation and feeding rate are appropriate for sheep.

“More minerals” is not automatically better. Copper availability also depends on other dietary components, including molybdenum and sulphur. Suspected deficiency should be investigated before adding copper supplements.

Sheep need the right amount of copper, not zero copper and not unrestricted supplementation.

Calcium needs attention before and after lambing

Growing lambs need calcium for skeletal development, while pregnant and lactating ewes need it for developing lambs and milk production. Cereal-heavy diets can be deficient unless properly balanced.

Sheep can develop hypocalcaemia during late pregnancy as well as after lambing. Do not assume that “milk fever” only affects animals already producing milk.

Importantly, do not copy a dairy-cow calcium restriction programme into a ewe ration without specialist advice. Sheep-specific guidance emphasises maintaining adequate calcium supply and minimising stress and time off feed around lambing.

Rams and wethers also need attention to urinary stone risk. Mineral balance and reliable water intake matter, particularly in concentrate-fed animals. Ask your veterinarian or nutritionist to assess the complete ration rather than adding minerals at random.

Pregnancy and litter size can change the feeding priority

Ewes carrying multiple lambs need careful management in late pregnancy. Their nutritional demands increase, and inadequate intake can contribute to pregnancy toxaemia.

Pregnancy scanning allows ewes to be grouped by litter size, while body condition assessment identifies those needing additional support. Maintain consistent access to suitable feed and avoid unnecessary periods without food.

A heavily pregnant ewe that stops eating, separates from the flock or becomes dull needs prompt veterinary assessment. Pregnancy toxaemia and hypocalcaemia can look similar and require different treatment approaches.

Can meat sheep and dairy sheep share feed?

They can often share forage and some formulated products. Whether the same ration suits them depends on intake, growth, milk production, pregnancy and body condition.

A feed suitable for a dry ewe may undersupply a milking ewe or young lamb. A rich production ration may be unnecessary for an adult maintaining condition.

Where practical, group sheep by nutritional need. Useful groups include growing lambs, finishing lambs, dry ewes, ewes carrying multiples and ewes in milk. This makes it easier to direct feed towards the animals that need it.

Milk-fed lambs require their own rearing programme. Adult sheep pellets do not replace colostrum or milk, and lambs need suitable starter feed as they develop towards weaning.

How to choose the right sheep feed

1. Identify the group and goal. Record liveweight, body condition, pregnancy status, litter size and intended growth or milk production.

2. Assess available forage. Check both its quality and how much sheep can actually access.

3. Use feed analysis. Test representative hay, silage or other major ingredients and compare results on a consistent basis.

4. Identify the limiting nutrient. Decide whether the gap is energy, protein, effective fibre, minerals or total intake.

5. Check the product label. Confirm suitability for sheep, feeding rate, copper content and any medication restrictions.

6. Introduce changes gradually. Follow an adaptation plan when adding grain or changing concentrates.

7. Measure the response. Monitor lamb weights, ewe condition, milk output, appetite and health.

Compare the cost of useful nutrients, including wastage, storage and delivery. The cheapest bag may not fill the nutritional gap your flock actually has.

For wool-covered sheep, assess body condition by feeling the loin rather than judging appearance alone. A substantial fleece can hide a substantial loss of condition.

When should you investigate a feeding problem?

What you notice	Possible concern	What to do
Slow growth or declining milk output in otherwise bright sheep	Inadequate intake, forage quality or ration balance	Review feed, water and production records
Reduced appetite or diarrhoea after increasing grain	Acidosis or another digestive problem	Contact your veterinarian promptly and stop further grain increases
A late-pregnant ewe becomes dull or stops eating	Pregnancy toxaemia, hypocalcaemia or another illness	Seek veterinary assessment promptly that day
Repeated straining with little or no urine	Possible urinary obstruction	Seek emergency veterinary help immediately
Severe bloating, breathing difficulty, collapse or inability to stand	Potentially life-threatening illness	Seek emergency veterinary help immediately

Acidosis can follow excessive grain intake, and urinary obstruction is a particular concern in male sheep. These problems need more than a change of feed brand.

Poor production also warrants a health review. Worm burdens, dental problems, lameness and udder disease can interfere with intake or performance. Investigate persistent deterioration rather than repeatedly adding supplements.

Common feeding mistakes

• Assuming all meat sheep have low nutritional requirements.

• Feeding cattle or goat minerals without confirming sheep suitability.

• Comparing wet feed prices without considering dry matter.

• Buying extra protein when energy or intake is limiting production.

• Increasing grain too quickly or offering it to hungry, unadapted sheep.

• Overlooking litter size, male urinary health or condition hidden beneath wool.

Keep the feeding system working

Provide fresh, accessible water and check trough cleanliness and refill rates daily. Requirements change with milk production, temperature and feed moisture, so one fixed water allowance will not suit every group.

Maintain consistent feeding, provide sufficient access for timid animals and reassess the ration when pasture quality or production changes. Introduce grain gradually and avoid prolonged interruptions followed by a large feed.

Frequently asked questions

Can dairy sheep eat lamb-finishing pellets?

Possibly as part of a properly balanced ration, but check the formulation and label first. A finishing product may not supply the protein balance, minerals or feeding instructions appropriate for milking ewes.

Can meat lambs eat dairy sheep pellets?

Sometimes, but an adult ewe feed is not automatically suitable for young lambs. Check energy, protein, minerals and the intended feeding rate, particularly for male lambs.

Can sheep live on grass alone?

Suitable pasture can meet many sheep’s needs, with mineral supplementation where required. Growing lambs and high-producing ewes may need additional feed when pasture quality or intake is inadequate.

Should sheep receive copper-free feed?

Sheep require some copper. The aim is an appropriate total intake, assessed alongside the rest of the diet. Use sheep-specific products and seek advice before adding separate copper supplements.

Does more protein mean more milk or faster growth?

Only when protein supply is limiting. Energy intake, digestibility, water, health and the balance of the whole ration also determine the response.
