Categories: ,


Active ingredient: 2mg/mL Hydroxocobalamin plus 4mg/mL Selenium

For the treatment of cobalt deficiency and Vitamin B12 and Selenium responsive conditions in sheep and cattle.

Before treatment, establish selenium and vitamin B12 status of stock and/or pasture cobalt levels.  Do not administer Cobalex 2000 plus Selenium injection unless deficienceis of both Cobalt and Selenium exist.  Cobalt deficiency in soil and/or pasture leads to a lack of vitamin B12 in body tissues of stock. Vitamin B12 deficiency is mostly a problem in very young stock. Poor growth rates and ill thrift may be seen in affected animals.

Treatment of vitamin B12 deficiency is likely to last only 4 – 6 weeks.  Redose with NON-Selenised vitamin B12 after this time if required

Treatment of pregnant animals should benefit newborn animals particularly when treated in the latter stages of pregnancy. Supplementation of young ruminants should begin at or before weaning.

The need for, and frequency of dosing is related to the severity of deficiency and age of the animal.

Seek veterinary advice if poor stock condition persists after treatment.

Do not use unless a selenium deficiency has been diagnosed.  Do not use at the same time as any other selenised fertiliser, prill or product without consulting a veterinarian

Administer by subcutaneous or intramuscular injection, into the anterior half of the neck.

Lamb 0.5mL, Adult Sheep 1-1.5mL   Cattle: 2.0 – 6.0mL
