- Abstract
The experiment was performed as a continuation of previous investigations carried out with pregnant and lactating sows and their offspring. Weaned piglets were divided to three experimental groups. Group I (control) received the mixture containing high levels of inorganic forms of Cu, Zn, Mn and Fe. Piglets of group II were fed the mixture containing mineral salts partially replaced with low level of soya amino acid based chelates of examined elements. In group III the same amount of micreoelements was given as in group II, however the cristalline glycine based chelates were applied. In the experiment the growth rate, feed intake and utilisation were examined. Moreover, the blood has been sampled and in serum the proteinogram (protein fraction pattern) as well as other physiological and biochemical indices characterizing animals health were evaluated. In the blood, bones, liver and meat tissue the concentration of minerals were determined. Higher growth rate and better feed utilization were noted in groups fed the organic sources of examined metals. In the liver of control animals higher deposition of Cu i Zn was observed.
