To increase calcium in sheep, particularly when they are fed cereal grain supplements, you can add limestone to their diet.
Providing adequate calcium is essential for sheep health, especially when their primary feed source is low in this vital mineral. Cereal grains, commonly used as supplements for ewes and growing stock in summer and autumn, are naturally low in both calcium (Ca) and sodium (Na). This dietary deficiency can lead to health issues if not corrected.
Methods for Increasing Calcium Intake
Based on recommendations for sheep being fed cereal grain supplements, limestone is a key supplement to provide calcium.
- Adding to the Diet: A recommended method is to mix limestone directly into the sheep's feed ration. This ensures consistent intake by all animals.
- Recommended Ratio: Add 2% limestone of the total ration weight.
- Combined with Salt: It's also recommended to add 0.5% salt at the same time, as cereal grains are also low in sodium.
- Providing as a Loose Lick: If mixing into the diet is not feasible or preferred, limestone (along with salt) can be offered separately as a loose lick for the sheep to consume ad lib (as much as they want).
Why Supplement Calcium?
Sheep, like other livestock, require calcium for bone development, muscle function, milk production, and various metabolic processes. When diets, such as those heavily reliant on cereal grains, don't provide enough calcium, supplementation is necessary to prevent deficiencies and maintain health and productivity.
| Feed Type | Calcium Level | Sodium Level | Supplementation Needed? |
|---|---|---|---|
| Cereal Grain | Low | Low | Yes |
| Recommended Additive | Limestone (Ca) | Salt (Na) |
Ensuring sheep receive sufficient calcium, especially during critical periods like growth or lactation, is crucial for their well-being and performance. Supplementing with limestone is a practical and effective way to address potential calcium deficiencies associated with certain feed types.
