W badaniach strawnościowo-bilansowych, wykonanych na młodym bydle opasowym, określano absorpcję i retencję cynku oraz miedzi z dawek pokarmowych, zawierających w swoim składzie siarczany i tlenki Zn i Cu. Najlepsze wykorzystanie cynku i miedzi stwierdzono u zwierząt otrzymujących 80 i 90 mg Zn·kg⁻¹ i 10 mg Cu·kg⁻¹. Wielkość absorpcji i retencji cynku oraz miedzi wyraźnie zależała od ilości tych pierwiastków w dawce, a także od rodzaju zastosowanych dodatków. Wyższą absorpcję i retencję Zn jak i Cu stwierdzono u byczków otrzymujących te pierwiastki w formie siarczanów niż tlenków.In balance-digestibility experiments carried out on young beef cattle the absorption and retention of zinc and copper from diets containing zinc and cop-per in sulp...
