Description

CUE Injection – 250ml

CUE injection is for the treatment and prevention of copper deficiency in cattle.

Each mL contains: Copper (as Calcium Copper Edetate) 50 mg

Testing for Copper Deficiency:

Monitoring the herd using either liver biopsies or samples from cull cow livers2 is recommended to complement blood, pasture and soil analysis.

The liver is the body’s storeroom for copper, containing up to 70% of the total body copper1. Copper levels in the blood will only
decrease when liver stores are exhausted.

Liver copper levels less than 100 μmol/kg fresh weight indicates depletion. In cattle 95 μmol/kg liver copper is considered
marginal, and less than 45 μmol/kg is deficient.

Aim is to keep concentrations above 95 μmol in Spring by attaining high liver copper in late Autumn. The recommended liver
copper “threshold” level for cows at drying off is at least 400 – 500 μmol/kg2.

Copper Supplementation:

Supplementing copper to dairy cattle during the period of zinc supplementation for facial eczema is no longer recommended as it
appears free copper ions in the liver may make cows more susceptible to the effects of facial eczema sporidesmin3.

Consequently, injecting copper at drying off, offers a practical means of achieving the target threshold.

(Australia) For the treatment and prevention of copper deficiency in cattle. (New Zealand) For the treatment and prevention of copper deficiency in cattle, sheep and deer.

Seek veterinary advice prior to treating a second time.
