متن کاملOpinion of the Scientific Panel on Additives and Products or Substances used in Animal Feed on the safety of Zeolite (sodium aluminosilicate, synthetic) for the reduction of risk of milk fever in dairy cows

Serum levels of copper and zinc as well as milk yield and composition are not affected by Zeolite treatm...
