Summary
In this article, you will find the latest veterinary approaches, diagnostic methods and treatment protocols on types of boluses for cattle and their uses.
What Is a Bolus for Cattle?
A bolus is a solid supplement product, typically cylindrical in shape, administered orally to cattle. Thanks to controlled-release bolus technology, active substances dissolve slowly in the rumen environment over hours or days, gradually entering the bloodstream.
Types of Boluses for Cattle
1. Calcium Bolus
Used for postpartum hypocalcemia (milk fever). Provides rapid and sustained calcium release.
2. Energy Bolus
Used to prevent negative energy balance and ketosis during early lactation. Contains propylene glycol and niacin.
3. Phosphorus Bolus
Used in cases of appetite loss and muscle weakness caused by postpartum phosphorus deficiency.
4. Performance (Mineral-Vitamin) Bolus
Used for comprehensive extended-release mineral and vitamin supplementation. Contains selenium, zinc, copper, cobalt, iodine, and B vitamins. Provides extended continuous release.
5. Calf Bolus
Used for immune system support and growth in newborn calves.
Bolus Supply in Turkey
Cattle bolus products in Turkey can be sourced from veterinary pharmaceutical companies and authorized distributors. Vetkim is a domestic company that produces and markets controlled-release bolus products throughout Turkey.
Things to Consider When Choosing a Bolus
- Target animal species and age
- Lactation period
- Identified mineral/vitamin deficiency
- Bolus weight and size
- Release duration
- Content and dosage
Conclusion
Correct bolus selection and timing minimizes metabolic disease losses on cattle farms, improving milk yield and reproductive success. Bolus protocols prepared under veterinary guidance deliver the most successful results.
