CobalJect 2000 B12 + Selenium

Categories: ,


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

Cobalt deficiency in soil and/or pasture leads to a lack of Vitamin B12 in body tissues of stock which, subsequently, may have poor growth and ill thrift, particularly in young animals.

Before treatment, establish selenium status of stock and pasture cobalt levels and/or Vitamin B12 status of stock.

Do not use this product unless animals are deficient in both both Cobalt and Selenium.  C

Treatment  is likely to last only 4 – 6 weeks if liver storage levels of Vitamin B12 and pasture levels of cobalt are low.

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

DO NOT use at the same time as any other selenised fertiliser, prill or product without consulting a veterinarian.

Seek veterinary advice if poor stock condition persists after treatment.

Do not dose within 3 months of the previous dose.

Administer by subcutaneous (under the skin) injection to be given into the anterior half of the neck.

Do not exceed stated dose.

Lamb 0.5mL at tailing or weaning,  Adult Sheep 1-1.5mL pre-lambing,   Calves: 2-3mL from 2 months of age,  Cows: 4.0 – 6.0mL pre-calving

Do not redose with this product within three months of the previous dose. Within this period re-treat with a non-selenised Vitamin B12 supplement.
