Feeding Donkey with Corn Silage
This page analyzes the use of corn silage as a feed source for donkey. At 8% crude protein and 70% TDN, corn silage is fully suitable as a sole feed for donkey at maintenance level (requires 8% CP and 50% TDN). Below you will find daily feeding rates, costs across herd sizes, and a life-stage breakdown showing how requirements change through the production cycle.
Corn Silage for Donkey by Life Stage
Feed requirements change significantly across life stages. The table below shows the daily as-fed quantity of corn silage needed for each donkey life stage, along with whether the feed meets the adjusted protein and TDN requirements for that stage. Life stages with higher demands (lactation, growth) may require supplementation even if corn silage is adequate at maintenance.
| Life Stage | Daily DMI | As-Fed/Day | Protein Need | Protein OK? | Monthly Cost |
|---|---|---|---|---|---|
| Maintenance | 7.5 lbs | 21.4 lbs | 8% | Yes | $16.07 |
| Pregnant Jenny | 8.6 lbs | 24.6 lbs | 10.4% | No | $18.48 |
| Lactating Jenny | 9.8 lbs | 27.9 lbs | 11.2% | No | $20.89 |
| Growing Foal | 9.0 lbs | 25.7 lbs | 12% | No | $19.29 |
Herd Feed Budget: Donkey on Corn Silage
For operations feeding corn silage to multiple donkey animals, the table below projects total feed requirements and costs. These estimates use the maintenance-level feeding rate of 21.4 lbs as-fed per head per day at $50/ton.
| Head Count | Daily As-Fed Total | Monthly Tons | Annual Tons | Monthly Cost | Annual Cost |
|---|---|---|---|---|---|
| 1 | 21.4 lbs | 0.11 tons | 1.37 tons | $16.07 | $195.54 |
| 5 | 107.2 lbs | 0.56 tons | 6.84 tons | $80.36 | $977.68 |
| 10 | 214.3 lbs | 1.13 tons | 13.69 tons | $160.71 | $1,955.36 |
| 25 | 535.8 lbs | 2.81 tons | 34.22 tons | $401.79 | $4,888.39 |
| 50 | 1,071.5 lbs | 5.63 tons | 68.44 tons | $803.57 | $9,776.79 |
| 100 | 2,143.0 lbs | 11.25 tons | 136.88 tons | $1,607.14 | $19,553.57 |
Feeding Rates by Body Weight
The daily amount of corn silage varies with the individual animal's body weight. The table below shows as-fed feeding rates and monthly costs across a range of weights for donkey.
| Body Weight | Daily DMI | As-Fed/Day | Monthly Feed | Monthly Cost |
|---|---|---|---|---|
| 350 lbs | 5.3 lbs | 15.0 lbs | 158 lbs | $11.25 |
| 425 lbs | 6.4 lbs | 18.2 lbs | 191 lbs | $13.66 |
| 500 lbs | 7.5 lbs | 21.4 lbs | 225 lbs | $16.07 |
| 575 lbs | 8.6 lbs | 24.6 lbs | 259 lbs | $18.48 |
| 650 lbs | 9.8 lbs | 27.9 lbs | 293 lbs | $20.89 |
Nutritional Analysis: Corn Silage for Donkey
Corn Silage provides 8% crude protein on a dry matter basis, while donkey at maintenance require a minimum of 8% crude protein. This means corn silage provides 0 percentage points of protein above the minimum requirement, giving adequate margin for variation in feed quality and individual animal needs.
For energy, corn silage provides 70% TDN compared to the donkey requirement of 50% TDN. The energy content is adequate for maintenance and provides 20 percentage points of margin. Higher-demand life stages such as lactation or rapid growth may require energy supplementation with grain or fat even though the maintenance requirement is met.
The dry matter content of corn silage is 35%, meaning that for every 100 lbs of as-fed feed, the animal receives 35 lbs of actual dry matter nutrition and 65 lbs of water. At $50 per ton as-fed, the effective cost per ton of dry matter is $143. When comparing feeds, always use the dry matter cost rather than the as-fed cost to make fair comparisons between feeds with different moisture levels.
For a comprehensive feeding program, consider combining corn silage with complementary feeds that address any nutritional gaps. Browse the complete feed comparison to identify the most cost-effective supplements, or use the calculator to model different feed combinations. Always provide free-choice mineral supplementation and clean water regardless of the forage and grain program.
