Kyrovite A-E injection

Categories: ,

Description

KYROVITE A-E injection is a high-potency aqueous of Vitamin A and E. It is a milky, yellowish-white fluid of low viscosity.

Vitamin A is the only vitamin commonly deficient in diets of range livestock. The deficiency occurs either as a primary disease due to an absolute deficiency of Vitamin A or its precursor carotene in the diet or as a secondary disease in which the dietary supply is adequate but digestion, absorption or metabolism is interfered with to produce a deficiency.

The major pathophysiological effect of Vitamin A deficiency are well-known and include night-blindness, cerebrospinal fluid pressure, distorted bone growth, atrophy of epithelial tissue, multiple congenital effects and loss of immune mechanism function.

Traditional forms of treatment have included the use of oily solutions of vitamin. However, the preference now is for aqueous forms of the injection because of their greater bioavailability. Aqueous emulsions of Vitamin A have been shown to have improved bioavailability compared to other types of formulation (see bar chart).
