Sheep — Maintenance Ewe Feed Requirements

Ewes in the maintenance phase between weaning and breeding require modest nutrition. Protein needs are 8-10%. Good quality grass hay or pasture meets most requirements. Provide trace mineral salt formulated for sheep (copper-free or very low copper).

Maintenance Ewe Feeding at Different Body Weights

The daily feed requirements for sheep in the maintenance ewe stage vary directly with body weight. The table below shows how dry matter intake, protein needs, and monthly feed costs change across a range of body weights. The DMI adjustment of 1x is applied at every weight level, reflecting the consistent metabolic demands of this production phase regardless of the individual animal's size.

Body Weight Daily DMI Daily Protein Daily TDN Monthly Feed Monthly Cost*
105 lbs 3.2 lbs 0.3 lbs 1.7 lbs 95 lbs $8.05
122 lbs 3.7 lbs 0.4 lbs 2.0 lbs 110 lbs $9.36
140 lbs 4.2 lbs 0.4 lbs 2.3 lbs 126 lbs $10.74
158 lbs 4.7 lbs 0.5 lbs 2.6 lbs 142 lbs $12.12

*Monthly cost estimated using grass hay at $150/ton.

Feed Options for Sheep (Maintenance Ewe)

Different feeds provide varying levels of protein and energy for sheep in the maintenance ewe stage, which requires a minimum of 10% crude protein and 55% TDN. The table below compares common feeds, showing the as-fed daily quantity needed to meet the dry matter requirement and whether each feed meets the protein and TDN thresholds as a sole feed source.

Nutritional Management Tips for Maintenance Ewe

Proper nutritional management during the maintenance ewe phase is critical for sheep health, productivity, and profitability. The DMI adjustment factor of 1x reflects the baseline metabolic demands of this production phase compared to maintenance. Similarly, the protein adjustment of 1x maintains the dietary crude protein requirement to 10% of dry matter.

When formulating rations for this stage, start with the forage base and determine how much of the protein and energy requirements it provides. If the forage alone does not meet the protein or TDN requirements shown in the feed comparison table above, supplement with protein concentrates (soybean meal, cottonseed meal) or energy sources (corn, barley, fat supplements) to fill the gap. Always make dietary changes gradually over 7-14 days to allow the digestive microbiome to adapt, particularly for ruminant species where sudden changes can cause acidosis, bloat, or other digestive disturbances.

Water intake is closely linked to dry matter intake and is often overlooked in feeding calculations. As a general rule, livestock consume 2-4 lbs of water per lb of dry matter consumed, with lactating animals at the high end of this range. Ensure that clean, fresh water is available at all times, as even mild dehydration reduces feed intake and animal performance. During winter, heated water sources prevent freezing and maintain intake. During summer heat, shade and ventilation reduce heat stress that can depress feed intake by 10-20%.

Monitor body condition scoring (BCS) regularly to verify that the feeding program is achieving the desired results. Animals gaining or losing condition outside the expected range indicate that feed quality or quantity needs adjustment. Laboratory analysis of forage samples ($15-$30 per sample) provides accurate protein and energy values for your specific hay or silage, which may differ significantly from the book values used in this calculator. Hay quality varies by cutting, maturity at harvest, storage conditions, and weather during the curing process, making testing the most reliable basis for ration formulation.
