J. A.  aNeutron activation analysis of zinc in forages used in intensive dairy cattle production systems.h[electronic resource]  c2002  aInstrumental neutron activation analysis (INAA) was applied for the determination of Zn concentration in the main tropical grass forages used in intensive dairy cattle production systems, in Brazil. Smaller Zn concentration could be verified in the rainy period. Comparison of results obtained in these analyses of forages dry matter with daily requirements pointed towards deficiency of Zn in the forages.  azinc  aNeutron activation  aTropical forages1 aPIASENTIN, R.
