Feed Additives with the Inclusion of Co and Mn Change Their Bioavailability and Digestibility of Substances in Bull Calves

In accordance with the scheme of the experiment animals in the control group received the basic diet (BD), Experimental Group I–BD + feed additive, replacing 30% of the concentrated part of the ration with the inclusion of salts of sulfates of cobalt and manganese, Group II – BD + feed additive, rep...

description In accordance with the scheme of the experiment animals in the control group received the basic diet (BD), Experimental Group I–BD + feed additive, replacing 30% of the concentrated part of the ration with the inclusion of salts of sulfates of cobalt and manganese, Group II – BD + feed additive, replacing 30% of the concentrated part of the ration with the inclusion of nano - and microparticles of cobalt and manganese. In situ studies found that the dry matter digestibility of feed additives containing chemically pure metal particles of cobalt and manganese and inactivated feed yeast was 15.4-20.0% (P
