Each application consists of a bolus and a capsule.
A rosin based, green cylindrical bolus, containing 1700mg iodine, 250mg selenium and 500mg
A maroon capsule, containing 12.5g of copper oxide needles.


Tracesure Cu/I Calf is a ruminal bolus and capsule for calves, providing slow release
supplementation of copper, iodine, selenium and cobalt. Where dietary intake of copper, iodine,
selenium or cobalt is low, or where utilisation of iodine is depressed by forage goitrogens, or
where forage has a high molybdenum content, the health and productivity of the animal may
be improved by supplementation of these elements.

Low copper intake gives reduced growth, depressed immunity and poor reproductive performance.
If left unchecked, it can lead to anaemia, lameness and thin, scouring, even dying animals.

Copper deficiency is caused by either low copper content (primary deficiency) or high
molybdenum, iron or sulphur content (secondary deficiency) in forage.
Goitrogens are substances commonly present in brassicas (cabbage family), soya and in
linseed meals, beet pulp and sometimes in pastures, which reduce the efficient utilisation of
iodine in maintaining thyroid function. The thyroid gland produces hormones which control
metabolism. Iodine deficient stock may suffer from reduced fertility (anoestrus, sub-oestrus), poor
weight gain and general ill thrift, late abortion/stillbirth/perinatal mortality, reduced milk yield and
quality, metabolic disorders as well as an increased susceptibility to infectious disease, scours, BRD
and parasitism.

Selenium deficient stock may suffer from white muscle disease, increased still births and
depressed fertility.

Cobalt deficient stock may have depressed appetites and/or show signs of general ill-thrift.

Tracesure Cu/I Calf boluses release supplementary copper, iodine, selenium and cobalt for up to 6
months. The iodine, selenium and cobalt are released from the bolus by leaching, providing
dietary supplementation. Spent boluses become enlarged and fragile. They are eventually shed,
intact or fragmented, by being regurgitated or excreted. A proportion of the administered copper
oxide lodges in the abomasum of the treated animal. This provides a sustained-release source
of copper for absorption from the gut. This steady supplementation ensures adequate copper
status but avoids the sharp rises in copper levels which can be associated with copper toxicity.


Tracesure Cu/I Cal f boluses are administered orally. Place both the bolus and the capsule at
the back of the mouth, beyond the hump of the tongue, using a suitable dosing gun (e.g. the
Animax Calf dosing gun). To avoid injury, the dosing gun should be used carefully and without force. Always check that the animal swallows both the bolus and the capsule.

Supplementation directions

Animals weighing 100 – 200kg: 1 maroon capsule and 1 green bolus. Both bolus and capsule from
the blister must be given together.


Give no other selenium supplement within 6 months except under veterinary advice. Tracesure
Cu/I Calf should not be used in areas where the herbage is of high selenium content. Tracesure
Cu/I C a l f should only be given if copper deficiency exists or is known to be a risk.
Not to be given to pre-ruminant animals. For animal use only. Keep out of the reach and sight
of children.


Tracesure Cu/I Calf should be stored under cool dry conditions in the original packaging and
should be handled carefully. In more humid conditions, and if the wax coating of the boluses has been
damaged, localised surface discolouration (grey-brown) may be seen. Such changes do not affect
the performance of the bolus.

Legal category
This is a complementary feed for calves.

Package quantities
Tracesure Cu/I Calf is available in packs of 20 applications.

Further information

Pasture analysis for trace element content is useful and laboratories undertaking this work can provide advice
on the need for supplementation. Pasture swards can vary greatly in their trace element content. Contaminant
soil can substantially alter the trace element supply.
Primary copper deficiency arises from a direct shortage of copper in the diet whereas secondary copper
deficiency results from the antagonistic effects of elements such as molybdenum, sulphur or iron upon
absorption. Tracesure Cu/I Calf is an effective long acting supplement in both cases. The severity of copper
deficiency, whether of primary or secondary origin, varies greatly from farm to farm. On most copper deficient
sites one dose of Tracesure Cu/I Calf, given to grazing calves at turnout, will maintain normocupraemia over
the grazing season and leave animals with a substantial liver copper reserve at housing.
