“…Vitamin A probably influences resistance to infections through its role in maintaining the integrity of the epithelial and mucosal membranes as well as affecting humoral and cell mediated immune responses (Beisel, 1982;Panda1 and Combs, 1963). Vitamin E has been shown to improve the humoral immune responses of mice, chicks, turkeys, swine, sheep, and guinea pigs when challenged with either nonliving antigens,living bacteria, or live viruses (Beisel, 1982;Colnago et al, 1984;Ellis and Vorhies, 1976;Heinseling et al, 1974;Nockels, 1980). Blazer and Wolke (1984) found that rainbow trout (Salmo gairdneri)…”

EXECUTIVE SUMMARYThe Abernathy Salmon Culture Technology Center (A.S.C.T.C.) and the Department of Microbiology at Oregon State University, with funding from the Bonneville Power Administration, are presently conducting a study on the effects of vitamin nutrition on immunity and disease resistance in chinook salmon (Oncorhynchus tshawptscha). The long range goal of this project is to define the dietary levels of pyridoxine, folic acid, pantothenic acid, riboflavin, ascorbic acid and vitamin E required to assure maximum resistance to disease.In the third year of this study we have completed the vitamins riboflavin and pantothenic acid. We first approximated dietary concentrations of these vitamins s that would exert the greatest e ffects on the immune response of salmon. Appropriate vitamin concentration ranges for both vitamins were then tested in a practical (Abernathy diet) and a semi-purified (modified Oregon Test Diet) ration to determine what concentration of vitamin would be required to gain some beneficial effects in a practical feed, and to determine the absolute requirements for immunological sufficiency.Results indicate that there are marginal differences in the immunological parameters tested withrespect to the Vitamin concentrations incorporated into the diets. However, the in vitro and in vivo studies --e -indicate that the Abernathy diet can provide greater enhancement of the development of immune responsiveness over that seen with the semi-purifies diet. This may be related to the increased growth rate or feed conversion of fish maintained on the Abernathy diet. 1The vitamins chosenfor study were pyridoxine, pantothenic acid, riboflavin, folic acid, Vitamin E, and ascorbic acid. A practical fish feed formulation and a semi-purified test diet are to be compounded to contain incremental amounts of the test vitamins. Each vitamin will be studied singly while dietary levels of all other vitamins are held constant, using the supplementation rates specified C in the vitamin packages for each diet.The test diets are fed for up to 24 : weeks to duplicate lots of spring chinook juveniles held indoors in circular tanks supplied with well water.During rearing, each lot of fish is weighed biweekly and dead fish are removed and recorded daily to: (1) determine growth rates, (2) calculate food conversion efficiencies, (3) provide population weights on which to base feeding rates, and (4) determine survival rates. Samples of test feeds are analyzed regularly to verify vitamin dietary concentrations, and fish organs will be analyzed for vitamin levels at the termination of each study.

“…Often selenium and vitamin E are supplemented together. Colnago et al (1984) challenged broiler cockerels with E. tenella oocysts; graded selenium levels from 0.1 to 1.0 ppm or 100 ppm of vitamin E/kg were added to the diet from day one of age. Dietary supplementation of at least 0.25 ppm selenium or vitamin E reduced mortality and increased weight gain.…”

Authors overlook the recent findings in the field of the complex interrelationship among nutrition, immune status and parasitic infestation. After summarizing the general characteristics of the active immune system, they describe the first period of the systemic immune response, the acute phase reaction. The cause of drastical decrease in serum zinc concentration is redistribution into the liver and lymphocyte metallothioneins. Immune deficiency correlates only indirectly with the nutrition. Ingestion of feed mycotoxins (e.g. T-2 toxin) and peroxides causes lymphocytes depletion in the lymphoid organs. Events of immunological stress are a special form of homeorrhetic control. Lack of energy and protein hardly damages the humoral immunity. Undernutrition fundamentally affects the cell-mediated immune response and the complement production. In animals, the lack of calcium, magnesium, iron, zinc, copper, iodine and selenium has been associated with signs of immunodeficiency. The concentrations of trace elements required for healthy animals are often below what is required for animals experiencing an immunological challenge. Zinc has both specific and aspecific role in the immune defence mechanism. Zinc regulates the maturation and function of immune cells, among others by protecting developing lymphocytes from apoptosis. As part of the zinc-finger proteins, may influence DNA transcription. The thymus synthesizes a 9-amino acid peptide hormone, the thymulin, which is activated after having bound zinc. Selenium has a vitamin E-independent immunostimulant effect in the marginally supplied animals. Active form of vitamin D 3 regulates transcription at cell level, acts as an immunomodulator and promotes phagocytosis. Lack of essential fatty acids in the diet of experimental animals caused atrophy of lymphoid organs and the reduction both the T-cell mediated and the independent immune response. Practical application of the new immunological findings is the segregated early weaning (SEW). Feed allergy results either in immediate hypersensitivity reaction within 1 to 2 hours or a T cell-mediated delayed hypersensitivity reaction within days. Under a certain number of worms ("threshold value") the host organism did not show detectable changes. Parasitic infection changes the body and skeletal composition: the water content increases, that of protein and fat drop; the calcium and phosphorus concentration of bones decreases. Helminths, developing in the animal, may cause serious local lesions; anaemia and the change of plasma proteins. Worms' toxins stimulate the production of gastrointestinal hormones, causing reduction in voluntary feed intake. Rabbits with biliary coccidiosis significantly decreased voluntary feed intake and the digestibility of the fats. The extent of infection and the oocyte excretion of Eimeria maxima in growing chickens showed a strong negative correlation with the plasma carotenoid level and strong positive correlation with the blood nitrogen oxide and γ-interferon concentration.Keywords: ac...
