The age at which the first injection is given, and the need for repeat doses, should be discussed with your veterinarian. In general, this will be related to the severity of the deficiency and the age of the stock. Cobalt deficiency in soil and/or pasture leads to sub-optimal levels of vitamin B12 in body tissues of stock which, subsequently, may have poor growth rates and ill thrift, particularly in young animals. Before treatment, establish pasture cobalt levels and/or vitamin B12 status of stock. Treatment of pregnant ruminants should benefit newborn animals, particularly when treated in latter stages of pregnancy.

Supplementation of young ruminants should begin at, or before, weaning. Treatment is likely to last only 4–6 weeks if liver storage levels of vitamin B12 and pasture levels of cobalt are low.
