Copper (Cu) accumulated in the livers of sheep receiving high levels of dietary Cu but low levels of molybdenum (Mo) and sulphur (S). However. the liver Cu accumulation was much lower than levels found in similar trials in the literature.…
A trial was conducted in which the rations of sheep were supplemented with different levels of Cu and Mo. The S intake was kept constant at 2,1 g/sheep/day. Two levels of Mo were fed, viz. 38 mg/sheep/day for 92 days…
Different levels of dietary S were supplied to sheep receiving high levels of Cu (55 mg/sheep/day) and Mo (34 mg/sheep/day) in their rations. At S intakes of 2,9,4,0 and 5,3 g/sheep/day the hepatic Cu retentions expressed as percentages of total…
Problems relating to the anticipation and elimination of poor production due to mineral deficiencies in grazing livestock will be examined in this paper. Its concern is with subclinical problems rather than catastrophic clinical problems. The ways in which hypothetical models…
Two trials were conducted to determine the effect of dietary molybdenum (Mo) on the fertility of young rams, when fed for ca. 14 weeks to prevent copper (Cu) toxicity. In the first trial, the sexual development of young weaner rams…
A study was conducted to test whether supplementation of trace elements would have any beneficial effect on year-old ewes receiving a submaintenance level of nutrition. The ewes were fed a poor quality hay. The control group received no supplementation (Treatment…
