Sheep boluses for targeted, long-term trace element nutrition
Maintaining balanced mineral levels is critical for promoting excellent lamb growth, maximizing ewe scanning percentages, and supporting overall flock thrive. Our curated range of Sheep Boluses provides a reliable, sustained-release method to deliver vital trace elements—such as cobalt, selenium, iodine, and copper—directly to your stock. Perfect for combating local soil deficiencies or supporting animals through high-stress transitions like tupping and pre-lambing, these slow-release capsules provide peace of mind for months at a time. To ensure safe, precise administration, pair these with our professional sheep bolus guns, and explore our wider sheep equipment selection to keep your livestock in peak condition.
Unlike loose minerals or liquid drenches, which provide a temporary spike in nutritional levels and require frequent administration, a high-quality Sheep Bolus resides safely in the reticulum (second stomach). Over several months, it erodes at a highly controlled, predictable rate, releasing a steady stream of essential trace elements daily.
This sustained-release technology guarantees that every animal in your flock receives the exact same daily nutritional intake, eliminating the risk of dominant sheep over-consuming pasture buckets while timid sheep miss out.
Key trace elements delivered by sheep boluses
Depending on your local soil composition and forage analysis, your flock may require different mineral combinations:
Cobalt: Absolutely essential for the synthesis of Vitamin B12, supporting energy metabolism, growth in growing lambs, and maternal instinct.
Selenium & Iodine: Critical for thyroid function, supporting strong lamb vigor at birth, and boosting ewe scanning percentages.
Copper: Crucial for skeletal development, wool quality, and nervous system health. *Note: Always verify your sheep's copper status before bolusing, as some breeds are highly sensitive to copper toxicity.*

Key Benefit
Sustained-Release Cobalt/Selenium
Breeding ewes, rams, and weaned growing lambs.
Enhances scanning percentages, lamb vigor, and weight gains.
Copper Oxide Capsules
Adult sheep on copper-deficient soils (highly antagonist soils).
Prevents swayback in lambs; improves fleece density and pigmentation.
Integrating boluses into your flock management
Most farmers choose to administer sheep boluses at critical milestones throughout the farming calendar. Bolusing ewes 3 to 4 weeks before tupping ensures optimum micronutrient levels for ovulation and embryo implantation. Alternatively, administering boluses to growing lambs post-weaning prevents growth slumps and supports healthy muscle development through the autumn months.
Frequently asked questions about sheep boluses
How long does a sheep bolus last?
Depending on the specific brand and formulation, most adult sheep boluses are designed to release trace elements consistently for up to 6 months.
Can I administer boluses to young lambs?
Yes, specialized small-diameter copper and trace element capsules are available for weaned lambs. Always check the manufacturer's minimum weight guidelines before using a sheep bolus gun on young animals.
What is the difference between a bolus and an oral drench?
An oral liquid administered with sheep drenchers provides an immediate, short-term boost of vitamins, while a bolus provides a continuous, slow-release supply over several months.
