CHELATE COMPOUNDS OF MICROELEMENTS FOR PIGS FATTENING

Abstract

The results of studies are presented with the aim to study the efficiency of feeding chelate compounds of trace elements of iron, copper, manganese and zinc in various concentrations on performance indicators of pigs during fattening. It has been determined that replacement of balancing zinc compound with a salt form to chelate form and 2 times decrease in concentration had practically no effect on animal performance. Chelate complexes of trace elements are optimal form of compounds of biogenic metals for animal body. Replacing conventional mineral supplement with a chelate supplement of elements allows to significantly reduce their introduction rate into diet and, as a result, reduce concentration in diets.
