Following blood sampling, plasma ammonia and oxygen  concentrations were determined. The portal ammonia concentration and  flow were significantly (P<0.01) affected by the diet (304 and 646 },

Plasma trace  element levels were monitored regularly over this period. At the end of  the trial the animals were slaughtered and various organis, muscle, skin  and wool were removed and analysed for a wide range of elements and for  metallothionein.   Zinc treatment resulted in significantly elevated Zn in plasma, red  blood cells, liver, kidney, intestine and pancreas. Copper  concentrations in liver (272 },
