Purina Accuration Hi-Fat: Best for Ketosis

Late-gestation ewes face a physical paradox where their energy needs are highest, but their stomach capacity is lowest due to growing lambs. Purina Accuration Hi-Fat addresses this by packing significant calories into a smaller volume of feed. This energy density is crucial for preventing the ewe from drawing too heavily on her own fat reserves.

The inclusion of Intake Modifying Technology is a standout feature that prevents “slug feeding” or overconsumption. This technology encourages ewes to eat small, frequent meals throughout the day rather than gorging all at once. This steady intake stabilizes blood sugar levels and maintains a consistent rumen pH.

When a ewe’s energy intake lags behind the demands of her developing lambs, her body begins breaking down fat rapidly, leading to ketosis, or pregnancy toxemia. The high-fat content in this mix provides a safer, more concentrated fuel source than starch alone. It bridges the gap during those final three weeks when the lambs are doing 70% of their growing.

If your management style involves group feeding where some ewes might dominate the bunk, this is your best option. The self-limiting nature of the feed ensures every animal gets what she needs without the risk of acidosis. It is the premier choice for shepherds who want to proactively shut the door on ketosis before it starts.

DuMOR Sheep Pellet 16%: Best Lactation Boost

Transitioning from the end of pregnancy to the start of milk production is the most nutritionally demanding period in a sheep’s life. DuMOR Sheep Pellet 16% provides the high protein levels necessary to kickstart strong milk let-down. A 16% protein profile ensures the ewe doesn’t have to “milk off her back,” which preserves her body condition for rebreeding.

The pelleted form of this feed is particularly advantageous for preventing waste and sorting. Ewes are notorious for picking through textured feeds to find the tastiest grains while leaving behind essential mineral fines. With a uniform pellet, you can be certain that every mouthful contains the balanced nutrition required for high-quality colostrum.

Colostrum quality is the single most important factor in lamb survival during the first 24 hours of life. This feed is fortified with the specific vitamins and minerals that enrich the ewe’s first milk, giving lambs a jumpstart on their immune systems. It provides a reliable nutritional foundation that supports both the mother’s recovery and the lamb’s growth.

This is the workhorse feed for the production-focused hobby farmer. If your primary goal is heavy weaning weights and ewes that bounce back quickly after lambing, this 16% pellet is the right tool for the job. It offers a no-nonsense approach to high-demand lactation support.

Manna Pro Sweet Feed: Best for Weak Ewes

Palatability is a major hurdle when dealing with a ewe that has lost her appetite late in pregnancy. Manna Pro Sweet Feed uses a touch of molasses to create an aroma and flavor profile that is nearly irresistible to sheep. This is often the only thing a “fussy” or sluggish ewe will agree to eat when she begins to flag.

The blend of cracked corn, oats, and barley provides a variety of carbohydrate sources that digest at different rates. This “textured” approach offers an immediate energy lift from the sugars and simple starches, followed by sustained energy from the more complex grains. It is designed to get the rumen moving and the blood sugar rising quickly.

Weak ewes often suffer from a lack of “gut fill,” which can lead to a displaced abomasum or general lethargy. The physical nature of sweet feed encourages chewing and saliva production, which are natural buffers for the digestive system. It provides a palatable way to deliver essential nutrients to animals that are otherwise disinterested in standard pellets.

Keep a few bags of this in the barn as your “emergency” ration. It is the ideal choice for bringing an underweight ewe up to condition or enticing a sick animal to keep eating through her recovery. When palatability is the difference between life and death, this sweet feed is the solution.

Nutrena Country Feeds: Best Prevention Mix

Nutrena Country Feeds offers a balanced, all-around nutritional profile that serves as an excellent preventative against common flock ailments. It is formulated to be a complete supplement that works alongside your existing hay or pasture. The consistent nutrient density helps avoid the “peaks and valleys” in nutrition that often lead to metabolic stress.

One of the most critical inclusions in this mix is ammonium chloride. While often associated with preventing urinary calculi in rams and wethers, it also plays a role in maintaining the proper mineral balance in the entire flock. Providing this in a daily ration simplifies your mineral management significantly.

This mix is specifically designed to be cost-effective for the hobby farmer who wants professional results without a complex feeding program. It scales well, whether you are feeding five ewes or fifty. The fortification levels are calibrated to support the average sheep’s needs through the stresses of winter and late gestation.

For the shepherd who wants a reliable, “set-it-and-forget-it” grain that covers all the bases, this is the winner. It is the best choice for those who value consistency and want to minimize the need for additional top-dressings or mineral blocks.

Tucker Organic Sheep Feed: Best Natural Pick

For those prioritizing organic principles or niche market lamb production, Tucker Organic Sheep Feed is the gold standard. It is crafted without GMOs, synthetic pesticides, or chemical preservatives, aligning with sustainable farming practices. The focus here is on the purity of the ingredients and the long-term health of the soil-animal cycle.

The use of high-quality whole grains rather than processed by-products supports a healthier rumen environment. Whole grains require more “rumination” or chewing, which naturally regulates the animal’s digestive pH. This results in a slower, more natural release of energy that mimics a forage-based diet more closely than high-starch pellets.

Many organic producers find that their ewes have fewer digestive upsets when fed a grain that lacks “filler” ingredients like soy hulls or peanut skins. Tucker focuses on recognizable, whole-food components that provide transparent nutrition. This transparency is vital for farmers who market their lambs as “all-natural” or “pasture-raised with organic supplement.”

If your farm’s brand relies on organic integrity or you have a personal commitment to avoiding synthetic additives, this is your feed. It provides the necessary boost for lambing season without compromising your commitment to natural husbandry.

Kalmbach 16% Sheep Pellet: Best for Selenium

Selenium deficiency is a silent killer in many parts of the country where the soil is naturally depleted of this essential trace mineral. Kalmbach 16% Sheep Pellet is specifically formulated with high-bioavailability selenium and Vitamin E to combat this issue. This combination is crucial for preventing “White Muscle Disease” in newborn lambs.

A selenium-deficient ewe will often give birth to “weak lambs” that lack the strength to stand and nurse. By providing a pellet with a precise, guaranteed analysis of selenium, you ensure the mineral crosses the placental barrier during late pregnancy. This builds the lamb’s reserves before it is even born.

Because selenium can be toxic in high doses, trying to “guess” the dosage with loose minerals can be dangerous. A commercially formulated pellet like Kalmbach’s takes the guesswork out of the equation. It provides a safe, metered dose that is evenly distributed throughout the feed, ensuring no ewe gets too much or too little.

This is the essential choice for farmers located in the Pacific Northwest, the Great Lakes region, or the Northeast. If you live in a selenium-deficient area, this pellet is a non-negotiable insurance policy for the health and vigor of your next lamb crop.

Transitioning Ewes to Grain Mixes Safely

The rumen of a sheep is a delicate ecosystem of bacteria and protozoa that requires time to adapt to dietary changes. Introducing grain too quickly can cause a massive die-off of these microbes, leading to a build-up of lactic acid. This condition, known as acidosis, can be fatal or cause long-term damage to the rumen lining.

A safe transition should take place over a period of 10 to 14 days. Start by offering just a small handful—roughly a quarter pound—of grain per ewe per day. Increase the amount by a small increment every two or three days, provided the ewes are still eating their hay and their manure remains firm.

• Day 1-3: 0.25 lbs per head
• Day 4-7: 0.50 lbs per head
• Day 8-11: 0.75 lbs per head
• Day 12+: Target amount (usually 1.0 – 1.5 lbs)

If you notice “clumping” manure or ewes that seem “off-feed,” back the ration down immediately. The goal is to support the ewe, not to overwhelm her digestive system. Consistency in feeding times also helps the rumen stay stable and productive.

Preventing Pregnancy Toxemia with Proper Feed

Pregnancy toxemia, or “Twin Lamb Disease,” occurs when the ewe cannot consume enough calories to fuel her body and the growing lambs. To compensate, she begins to burn her own body fat for energy. This process creates ketones, which are toxic in high concentrations and eventually lead to liver failure and death.

Managing this condition is primarily about caloric density and bunk management. Ensure that there is enough space at the feeder for every ewe to eat at the same time. If timid ewes are pushed away by dominant ones, those “shy” ewes are at a much higher risk of developing toxemia.

Overweight ewes are actually at a higher risk than moderately thin ones. This is because their internal fat stores take up space that the rumen needs to expand, and their heavy fat breakdown can overwhelm the liver more quickly. Aim for a “Body Condition Score” of 3.0 to 3.5 at the time of lambing for the best outcomes.

Balancing Minerals to Prevent Milk Fever

Milk fever, or hypocalcemia, is caused by a sudden drop in blood calcium levels right around the time of lambing. Unlike cattle, sheep often experience this before lambing rather than after. It is triggered by the high demand for calcium to produce colostrum and develop the skeletons of multiple fetuses.

The key to prevention is the ratio of calcium to phosphorus in the grain mix. You should aim for a ratio between 1.5:1 and 2:1. If phosphorus levels are too high, they can actually block the ewe’s ability to mobilize calcium from her own bones, leading to a crash in blood levels.

• Monitor for tremors: Early signs include twitching or a stiff gait.
• Check ear temperature: Ewes with milk fever often have cold ears due to poor circulation.
• Provide Vitamin D: Ensure your grain mix includes Vitamin D, which is essential for calcium absorption.

Using a fortified sheep pellet is much safer than using a “general livestock” mineral. Sheep have very specific requirements, and the wrong balance can lead to either milk fever or urinary stones.

Feeding Guidelines for Ewes Having Twins

A ewe carrying twins or triplets has significantly higher nutritional requirements than one carrying a single lamb. By the last month of pregnancy, a twin-bearing ewe may need up to 50% more energy. If she is fed the same as a single-bearing ewe, she will likely lose body condition and produce less colostrum.

The most effective way to manage this is through ultrasound scanning at mid-pregnancy. If you know which ewes are carrying multiples, you can sort them into a separate “heavy” group. This allows you to feed them the higher-quality, high-fat grains they need without overfeeding the single-bearers.

If sorting isn’t possible on your farm, you must feed for the “average” of the flock but watch the twin-bearers closely. Look for signs of the spine becoming prominent or the ewe lagging behind during move times. These individuals may need to be pulled out for supplemental “creep” feeding of a high-energy sweet feed or high-fat pellet.

Investing in high-quality grain during the final stages of pregnancy is the most cost-effective “insurance” a hobby farmer can buy. By preventing metabolic crises before they begin, you ensure a smoother lambing season and a more profitable, healthy flock.
