For a period of 8 weeks, rainbow trout (<jats:italic>Salmo gairdneri<\/jats:italic>), mean initial weight 21 g, were given either a low-magnesium or control diet containing 0\u00b703 and 0\u00b758 g Mg\/kg diet respectively. Both groups of trout were then given the control diet for a further 11 weeks.<\/jats:p><jats:p>2. Weight gains over the initial 8-week period were lowest in the Mg-deficient trout. Feeding the deficient fish the control diet rapidly improved growth rate until it was the same as that of the control trout.<\/jats:p><jats:p>3. Plasma Mg was significantly lower in the Mg-deficient trout at week 8. Feeding with the control diet for 11 weeks did not increase plasma Mg. Few changes were observed in the plasma concentrations of the other electrolytes.<\/jats:p><jats:p>4. Renal calcium concentrations were unaffected by dietary Mg levels. Similarly, the renal levels of phosphorus, sodium and potassium all fell within the range found in normal rainbow trout.<\/jats:p><jats:p>5. Muscle Mg concentrations were reduced in those trout given the Mg-deficient diet. Feeding with the control diet for a further 11 weeks increased muscle Mg but the level was still significantly lower than that found in trout given the control diet for 19 weeks.<\/jats:p><jats:p>6. The bone ash Mg concentration was significantly lower, and the Ca higher, in the deficient fish at week 8, when compared with the control group.<\/jats:p><jats:p>7. When compared with the value at the start of the experiment, total bone Mg fell slightly in the deficient trout over the initial 8-week period, but increased in the control group of fish. Feeding with the control diet for a further 11 weeks increased total bone Mg in both Mg-deficient trout and control trout.<\/jats:p><jats:p>8. The results show that the Mg deficiency imposed on the rainbow trout was of limited severity and almost complete recovery was obtained when the control diet was fed.<\/jats:p>","DOI":"10.1079\/bjn19830079","type":"journal-article","created":{"date-parts":[[2005,9,17]],"date-time":"2005-09-17T00:07:20Z","timestamp":1126915640000},"page":"121-127","source":"Crossref","is-referenced-by-count":20,"title":["Studies on the nutrition of rainbow trout (<i>Salmo gairdneri<\/i>) Magnesium deficiency: the effect of feeding with a Mg-supplemented diet"],"prefix":"10.1017","volume":"50","author":[{"given":"D.","family":"Knox","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
