“…The concentration in the liver and kidney was significantly higher than in blood, pineal or cerebellum. These results are in agreement with the results of Wright and Bell (1964) with sheep and Wright and Mraz (1964) with chickens, but they differ in some detail from results reported by Jensen et al (1963), with young chicks. The latter found the highest values in blood, followed in order by the spleen, kidney and liver.…”

“…2) and the rats fed the low fish selenium diet absorbed more than 90% of the selenium given (table II). An increasing relative reten tion when fed decreasing levels of selenium was previously reported for rats [ 12] and for chickens [11,15]. The absorption of sele nium was higher for selenite compared with fish selenium when fed at the same dietary level.…”

Rats of a normal selenium status were fed diets based on fish (rainbow trout) as the main protein source. A 4-week experiment with three dietary groups (low fish selenium, high fish selenium and selenite supplementation) was performed, and the selenium absorption, excretion and retention were recorded. Samples of blood serum, liver, kidneys, testes, hairs, spleen, lungs, heart, brain and skeletal muscle were collected for analysis of selenium. Glutathione peroxidase activity was measured in the blood serum. A selenium supplementation of approximately 1 mg/kg (high fish selenium and selenite group) yielded a selenium retention of only 7 % of the intake, while in the group with a dietary selenium concentration of approximately 0.1 mg/kg (low fish selenium group) the selenium retention was 50%, resulting in almost the same absolute selenium retention in all three groups. The liver and kidneys showed the highest accumulations of selenium, reflecting the participation of these organs in the excretion of surplus selenium. The highest relative uptake of selenium was recorded in the testes, which increased equally in all dietary groups. The selenium concentration in the other tissues investigated, as well as the glutathione peroxidase activity in the blood serum responded little to the selenium supplementations. These results showed that the selenium levels normally found in fish were sufficient to satisfy the need for this element in rats of a good selenium status, and that inorganic selenite was absorbed and excreted at a high rate already after 1 week.

Comparative Selenium Retention by Chicks Fed Sodium Selenite, Selenomethionine, Fish Meal and Fish Solubles

Two experiments were conducted to assay the retention of Se from varying levels of fish meal and solubles and in the second experiment to compare also the retention with that from comparable levels of sodium selenite and selenomethionine. The basal diet contained crystalline amino acid diets and high levels of a-tocopherol acetate (200 and 300 p.p.m.). In the first experiment day-old chicks were found to contain 11 fig. Se whereas chicks fed the basal diet for 21 days without any Se supplements contained 37% less. In the second experiment the day-old chicks started with a body reserve of 13 fig. Se, of which 35% was lost when fed the basal diet for 18 days.A Se balance in the chick was maintained by a dietary level of 0.05 p.p.m. from any of the sources studied. This quantity of Se was supplied by a dietary level of 2.5% fish meal or solubles. A level of 5% fish meal or solubles in the diet supplied about 0.1 p.p.m. total Se of which 16-29% was retained in the chick body in the first experiment and 15% in the second experiment. The retention value obtained in the second experiment, by supplying 0.1 p.p.m. Se from sodium selenite, was 35% and, therefore, in comparison the same levels of Se in fish meal or solubles was about 43% as effective as the standard. Compared to selenomethionine at the same level of Se, the fishery products were 31% as effective. ABSTRACTTwo experiments were conducted to determine whether the turkey poult could utilize inorganic sulfate. The basal diet contained 26 percent protein and 2987 kilocalories of productive energy per kilogram. Total sulfur amino acid content was 0.765 percent. Five additional diets were formulated by adding the following to the basal: 0.105 percent methionine, 0.25 percent Na 2 S0 4 , 0.105 percent methionine and 0.25 percent Na 2 S04, 0.21 percent methionine, and 0.21 percent methionine and 0.25 percent NajSO*. Each addition of methionine gave a significant growth response. Sodium sulfate gave a significant growth response only in the absence of added methionine, but numerical increases were evident at each addition. The addition of 0.21 percent methionine produced the only significant improvement in feed efficiency.
