Description
Marks-Min Injectable Trace Mineral With Vitamin B12 For Cattle is a trace mineral injection for cattle registered by Boehringer Ingelheim Animal Health Australia Pty Ltd (APVMA No. 87283/122204). Each litre delivers 10 g/L copper, 6.7 g/L manganese, 26.7 g/L zinc and 3.3 g/L selenium as chelated EDTA compounds. It also contains 1.4 g/L cyanocobalamin, the active form of vitamin B12. It corrects and prevents deficiencies in beef and dairy cattle that are deficient in, or responsive to, these minerals and vitamin B12.
When to Use This Trace Mineral Injection For Cattle
Trace mineral deficiency in copper, manganese, zinc and selenium is common in Australian cattle. Deficiency often peaks at calving, mating, weaning and drying off, exactly when demand for these nutrients rises. Oral and feed supplements can fall short here. Intake and absorption vary between individual cattle, and other minerals in the ration compete for uptake. An injectable trace mineral bypasses the gut entirely. It reaches the bloodstream directly, so cattle get a reliable dose regardless of what they are eating.
Growth, Reproduction, Immune Defence and Energy
Marks-Min supports four areas of production. Copper, manganese, zinc and selenium aid bone, joint and muscle development, which drives growth. The same minerals support fertility: they aid sperm development, ovulation, embryo survival and placental retention in females. They also support immune defence, helping white blood cells resist infection. Vitamin B12 adds the energy component. It drives DNA synthesis and red blood cell production, and fuels the energy metabolism that underpins every other process.
Dosing by Weight, Not Guesswork
Marks-Min doses by liveweight, not a flat rate. Calves and yearlings up to 1 year get 1.5 mL per 50 kg. Weaners and young stock from 1 to 2 years get 1.5 mL per 75 kg. Mature cattle over 2 years get 1.5 mL per 100 kg. This keeps dosing accurate across a mixed-age herd, from calves at marking through to bulls before joining.
Frequently Asked Questions
Q. What is Marks-Min Injectable Trace Mineral With Vitamin B12 For Cattle used for?
A. This trace mineral injection corrects deficiencies in copper, manganese, zinc, selenium and vitamin B12. Boehringer Ingelheim registers it for beef and dairy cattle that are deficient in, or responsive to, these nutrients. Producers typically use it before joining, calving, weaning or drying off.
Q. How much Marks-Min do I give cattle by weight?
A. Dose depends on age. Calves up to 1 year get 1.5 mL per 50 kg liveweight. Yearlings from 1 to 2 years step up to 1.5 mL per 75 kg. Mature cattle over 2 years take 1.5 mL per 100 kg. Always check the applicator’s accuracy before and during treatment.
Q. What is the withholding period for Marks-Min?
A. There is no withholding period. Meat, milk and export slaughter intervals are all zero days. Confirm the current ESI with the registrant before use, since trade requirements can change.
Q. How often can cattle be re-treated with Marks-Min?
A. Wait at least 8 weeks between treatments. This applies to all classes of cattle. Treatment frequency should still match your herd’s nutrient status, so consult your vet or animal health advisor for a supplementation plan.
Q. Can I use Marks-Min on cattle with high selenium or copper status?
A. No. Marks-Min is contraindicated when selenium intake from pasture, top dressing, vaccines, pellets or drenches is already high. It is also contraindicated where copper deficiency has not been confirmed, since excess copper is toxic. Ask your vet to check blood selenium and copper status before treating.
Q. Is Marks-Min comparable to MultiBoost with B12?
A. Yes. Both are chelated EDTA trace mineral injections with vitamin B12 for beef and dairy cattle. Both target copper, manganese, zinc, selenium and vitamin B12 deficiency. Concentrations differ: Marks-Min carries 10 g/L copper, 6.7 g/L manganese, 26.7 g/L zinc and 3.3 g/L selenium, while MultiBoost carries 15 g/L copper, 10 g/L manganese, 40 g/L zinc and 5 g/L selenium. Pack sizes differ too: Marks-Min ships in 500 mL and 1 L, MultiBoost only in 500 mL. The main difference is the registrant. Boehringer Ingelheim makes Marks-Min, while Elanco Australasia makes MultiBoost. Always compare both labels before you substitute one for the other
