Refinement of Vitamin Supplementation in Diets for Channel Catfish
نویسندگان
چکیده
Vitamins are often added to fish diets at levels above those required for normal growth. Fortification of diets in this manner may be done for a variety of reasons. Certain physiological processes or conditions such as reproduction, stress, or disease may increase the levels of vitamins needed by the fish to maintain normal growth, metabolism, and health. Certain vitamins, such as vitamin E, may be supplemented at levels above those required for normal growth to improve flesh quality during frozen storage by increasing the oxidative stability of processed fish products. In addition, some vitamins such as certain forms of vitamin C are susceptible to breakdown during feed processing and storage which reduces the amount of vitamin available to the fish. To compensate for these losses, diets are typically fortified with vitamin C at levels higher than established requirements.

Effects of dietary vitamin E on growth performance as well as intestinal structure and function of channel catfish (Ictalurus punctatus, Rafinesque 1818)
To evaluate the impact of dietary vitamin E supplementation on growth performance, the intestinal structure and function of channel catfish (Ictalurus punctatus, Rafinesque 1818) was investigated. A total of 900 healthy channel catfish (weight, 5.20±0.15 g) were divided into four groups, which received experimental diets with different vitamin E content (0, 50, 100 or 1,000 mg/kg). At the end o...
