Each application consists of 2 boluses:

  • A Rosin based cylindrical bolus, containing 3400mg iodine, 500mg selenium and 500mg cobalt.
  • A solid, rapidly dissolving bolus, containing 30g of copper oxide needles and 25mg of cobalt.

Supplementation Instructions:

Animals weighing 200 – 550kg: 1 application

Animals weighing 550kg and over: 2 applications

COPPER: high molybdenum and low copper intake gives reduced growth, depressed immunity and poor reproductive performance (hitting the pocket rather than the eye) BUT if left untreated it can lead to anaemia, lameness and to thin, scouring, dying animals.

Low copper intake and/or high molybdenum can lead to:-

reduced fertility

diarrhoea/dirty back ends

reduced growth rate

reduced resistance to disease

reduced milk production

depressed bull libido

joint disorders

reduced semen quality

bone deformities

spontaneous fractures

IODINE: whilst low iodine status is not uncommon, the clinical signs are variable, and can include reduced fertility (anoestrus or 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 diseases, scours and parasitism.

SELENIUM: a trace element generally widespread in nature, is frequently low or insufficient in good quality pastures and crops. If intake is low, stock may suffer from white muscle disease, increased still births and depressed fertility.

COBALT: is necessary for ruminants to  maintain the vital production of vitamin B12 by bacteria in the rumen. Low intake leads to depressed appetite and ill-thrift, which may come and go as grazing conditions alter, and may go unrecognised for years.

The Tracesure® range of intra-ruminal boluses release supplementary iodine, selenium and cobalt for up to 5-6 months. Trace elements 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, usually after 12 months.

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. Routine pasture analyses do not detect goitrogens1.

The animal’s iodine and selenium status may be assessed by blood sampling. Iodine status should be assessed by plasma inorganic iodine (PII) and selenium by glutathione peroxidase (GSHPx) assay. The T4 (thyroxine) test does not give a meaningful value for iodine intake. Animals with PII levels below 40µg/I are likely to show benefits in health and productivity from iodine supplementation.
