Lactating Ewe Nutrition: What to Feed Nursing Sheep

A lactating ewe has one of the highest nutrient demands in the flock. Her needs rise sharply after lambing because she is making milk while also recovering from late pregnancy. The first 8 to 10 weeks of lactation are usually the most demanding period. During that time, even a ewe that looks healthy can lose body condition if the ration does not provide enough energy and protein.

For most nursing ewes, the base diet should be high-quality forage such as leafy grass hay, mixed hay, legume hay, or well-managed pasture. Poor-quality mature hay often does not provide enough nutrition on its own, especially for ewes nursing twins or triplets. In those cases, your vet, flock consultant, or nutritionist may recommend adding grain, a balanced sheep pellet, or a protein supplement to support milk production and help maintain body condition.

Water and minerals matter as much as calories. Nursing ewes need constant access to clean water, and many will drink at least about 1.5 gallons daily under temperate conditions. They also need a sheep-appropriate mineral source that supplies salt and trace minerals without excessive copper. Selenium, calcium, and phosphorus balance can be especially important depending on your region, forage, and grain mix.

Body condition scoring is one of the most useful tools for pet parents and flock managers. A ewe that is milking heavily, carrying a rough fleece, or feeding multiple lambs may need ration changes before obvious weight loss appears. If you are unsure whether your ewe is getting enough, your vet can help assess forage quality, body condition, and whether the current feeding plan matches her stage of lactation.

There is no single safe amount that fits every lactating ewe. Intake depends on body weight, forage quality, weather, milk production, and whether she is nursing one lamb or several. As a practical example, Washington State guidance for a 175-pound ewe in early lactation suggests about 5 pounds of hay daily plus around 1.5 pounds of shelled corn for a ewe nursing a single lamb, about 2.25 pounds of corn for twins, and higher concentrate support plus soybean meal for triplets when hay quality is not enough.

Those numbers are starting points, not prescriptions. Better hay can reduce how much grain or protein supplement is needed. Lower-quality hay usually means more concentrate is required, but grain should be introduced gradually over several days to lower the risk of rumen upset, acidosis, or enterotoxemia. Sudden feed changes are a common cause of trouble in nursing sheep.

A simple field rule is to let forage do as much of the work as possible, then add concentrates only as needed to maintain milk production and body condition. Ewes on excellent pasture or high-quality alfalfa-mix hay may need little or no grain if they are nursing a single lamb. Ewes with twins, triplets, or thin body condition often need more support. Your vet or a sheep nutritionist can help adjust the ration if lamb growth is poor or the ewe is losing weight.

Feed costs vary by region, but 2025 US commodity and hay data support a rough daily feed cost range of about $0.80 to $1.40 for a forage-based lactation ration and about $1.50 to $2.50 or more per day when higher levels of alfalfa, grain, bagged sheep feed, or protein supplements are needed. Bagged textured sheep feeds are often the most costly option per unit of nutrition, while home-balanced forage and commodity grains may lower the cost range when managed carefully.

Watch for weight loss, a dropping body condition score, reduced milk production, hungry or slow-growing lambs, poor appetite, weakness, and a dull or rough fleece. These can all suggest that the ewe is not meeting her energy or protein needs. In early lactation, thin ewes feeding twins or triplets are at especially high risk for nutritional stress.

Also watch for signs linked to ration imbalance rather than simple underfeeding. Bloat, diarrhea, sudden off-feed behavior, depression, or signs of abdominal discomfort can happen after abrupt grain increases or spoiled feed. Mineral problems may show up as poor thrift, weak lambs, low milk yield, or in some regions white muscle disease related to selenium deficiency. Copper toxicity is another concern if sheep are given the wrong mineral product.

See your vet immediately if a nursing ewe becomes weak, separates from the flock, stops eating, has neurologic signs, goes down, or seems unable to care for her lambs. Those signs can point to serious problems such as ketosis, hypocalcemia, severe parasitism, toxicities, mastitis, or other illnesses that need prompt veterinary care.

If the problem seems milder, such as gradual weight loss or lambs that are not thriving, it is still worth contacting your vet soon. Early ration adjustments are usually easier and safer than trying to catch up after the ewe is already depleted.

If your current feed program is not keeping up with lactation demands, the safest alternative is usually not more random grain. It is a better-balanced ration. Options may include upgrading to higher-quality hay, adding a sheep-formulated pellet, using a measured amount of corn or barley, or adding a protein source such as soybean meal when forage protein is low. These changes should be made gradually and with attention to body condition, manure quality, and lamb growth.

For ewes that struggle on dry hay alone, high-quality pasture can be a very useful alternative when available. Legume-rich pasture or leafy mixed pasture may improve intake and reduce the need for purchased concentrates. In drought, winter, or heavy parasite seasons, though, pasture may not be enough by itself. Stored forage testing can help you avoid guessing.

A sheep-specific loose mineral and constant clean water are also safer alternatives than trying to correct problems with extra grain alone. Many nutrition issues in lactating ewes are really combination problems involving energy, protein, salt, trace minerals, and water access. Fixing only one piece may not solve the whole issue.

If a ewe is thin, feeding multiples, or raising lambs that are not gaining well, ask your vet whether forage analysis, fecal testing, or a ration review would help. Sometimes the best alternative is not a different feed ingredient. It is a clearer plan tailored to your flock, forage, and region.
