Investigation of the strength of copper and zinc bonds with other constituents of ruminant feedstuffs
ABSTRACT The objective of the present study was to evaluate the effect of feed type, pH, and Cu and Zn concentration on Cu and Zn binding with different feedstuffs after in vitro incubation in water. For this purpose, six feedstuffs (wheat straw, grass hay, corn silage, dried distillers grains with solubles, ground corn, and soybean meal) were incubated in ultrapure water (pH≈6.4) with supplemental Cu concentrations equivalent to 0, 5, 10, 15, 20, 30, and 40 mg Cu/kg DM or [...]
