Vitacare C is a Vitamin C, known to perform numerous biochemical and physiological functions in both plant and animal metabolism. Most animals can synthesize this vitamin in the form of ascorbic acid in amounts sufficient to prevent the clinical symptoms of deficiency collectively known as scurvy. However, primates, guinea pigs, fish, shrimp, and some insects, bats, and birds require a dietary source of vitamin C to prevent or reverse scorbutic symptoms. Among these species, dietary essentiality of vitamin C in fish and shrimp probably results from an absence or insufficiency of L-gulonolactone oxidase. This enzyme is required for biosynthesis of ascorbic acid from glucose or other simple precursors.

Vitacare C is a
strong reducing agent that provides electrons to functional groups of other
biochemicals and free radicals found in the aqueous phase of biologic fluids.
2.
Two biochemical
reactions commonly associated with the function of Vitacare C in animals are
hydroxylation and reduction.
3.
Vitacare C plays a
role as a cofactor in hydroxylating lysine and proline of collagen. This
protein is the major component of connective tissue, including bone and
cartilage. Impaired collagen formation results in the classical vitamin C
deficiency symptoms of scurvy. These include lordosis and scoliosis, as well as
poor growth, anorexia, reduced wound healing efficiency, and hemorrhaging.
4.
Vitacare C also
serves as a cofactor in hydroxylation reactions involved in excretion of drugs
and toxicants.
5.
Aside from these
biochemical processes affecting growth and morphogenesis of various species of
fish and shrimp, Vitacare C activity also has been linked conclusively to
reproduction as well as adaptive responses such as disease resistance.

A shrimp
requirements for Vitacare C, like any other vitamin, are actually the amounts
of vitamin activity required per kg of body weight per day to achieve specific
physiological responses. At any response level, these requirements are affected
by the size of the shrimp and its physiological state, as well as by nutrient
interrelationships and environmental factors (NRC).
2.
In general,
relatively low Vitacare C activity levels are sufficient for optimum growth and
feed conversion, which is usually, the desired response for shrimp that are
cultured for food. Maximal adaptive response, such as disease resistance and
tolerance to environmental stress, require slightly higher levels.
3.
Based on the
combination of experimental results and field experience, Vitacare C can be
recommended the following levels based on the vitamin C activity in feed at the
time that it is consumed:

Additionally, you can use approximate
minimum Vitacare C level of 1000 mg per kg feed whenever the immune system of
shrimp is challenged, such as handling and grading, disease outbreaks. This
recommendation is to feed this high level for two to four weeks before and at
least two weeks following these stressful events.
