Product Description

Cobalife VB12 Plus Selenium is an injectable Vitamin B12 and Selenium to treat and control Vitamin B12 and Selenium deficiency in sheep and cattle.

Vitamin B12 is a water soluble vitamin which acts as a coenzyme for various metabolic functions, including fat and carbohydrate metabolism and protein synthesis. It is vital for glucose production in ruminants, which is essential to meet the high energy demands of growth and lactation. Selenium is a trace element that is necessary for normal metabolism; it is an essential anti-oxidant, and key component of proteins that have a role in muscle function, immune system and synthesis of thyroid hormones.

Vitamin B12 deficiency results in reduced appetite and growth rates, illthrift, infertility and reduced wool and milk production. Selenium deficiency can result in lameness, White Muscle Disease, reduced fertility and immunity, and reduced wool and milk production. Deficiency may occur at any stage of the year but is more likely to happen during stressful periods such as calving/lambing and growing periods of stock. Subcutaneous injection of Vitamin B12 and Selenium is the preferred method of preventing and correcting Vitamin B12 and Selenium deficiency.
