Changes In The Whole Body Mineral Concentration Of The Rainbow Trout (Oncorchynchus Mykisswalbaum) Yolk-Sac Fry Exposed To Various Combinations Of Aluminium And Calcium Concentrations In Two Different Acidic Water, Meti̇n Çalta
Turkish Journal of Zoology
The effects of 12 combinations of pH (4.5 and 7.0), aluminium (4 and 8 ?mol/L) and calcium (10 and 100 \mumol/L) on survival and body mineral (Ca, Mg, K and Na) concentrations of rainbow trout ( Oncorhynchus mykissWalbaum) at the yolk-sac stage were investigated. Mortality was low (< 17%) in most combinations and increased (> 27%) in the presence of aluminium and low pH (4.5). Aluminium (4 and 8 ?mol/L) impaired larval development, net uptake of calcium, potassium and sodium, and slightly increased the net loss of magnesium. It was found that these effects of aluminium were more severe at low calcium concentration (10 ?mol/L) and low …

Use Of The First Carbonification Studge Of Sugar Industry As Calcium Source In Quail Diets, Ni̇hat Özen, Emi̇n Arat
Turkish Journal of Veterinary & Animal Sciences
The use of first carbonification sludge (waste-clay), a waste product of sugar industry, was investigated as a calcium source in quail diets in two consequtive trials. In the first experiment 1260 of 10-day old Japanese quails were used in a period of 45 days, while 432 quails were utilized during the following 24-weeks laying experiment. Ground marble was replaced by the sludge in the experimental diets to supplement the Ca requirements at the rates of 0, 20, 40, 60, 80 and 100 %, respectively. Variance analysis of data obtained from the growth experiment indicated that there were no significant differences …
