Abstract: The aim of this study was to investigate the influence of feeding rations with different nutritional value, that included either the grass meal of Amaranthus cruentus L. (AGM) or products of AGM hydrolysis-extraction enriched with pectin or purified amaranth pectin, on the indices of erythropoiesis of commercial layer replacement chickens, their growth performance and liveability. Chickens had some dysfunctions in the erythropoiesis during the period of intensive growth, accomplished with the higher spending of iron or due to the change of composition and nutritive value of the ration. The therapeutic and prophylactic effect of all above mentioned products on erythropoiesis of chickens has been reviled. It was indicated by the increased hemoglobin concentration, number of erythrocytes and normalization of a single erythrocyte’s indices. Moreover, the use of AGM and its products of hydrolysis-extraction resulted in the elevated growth performance and liveability of young pullets. The dose-dependent effects of investigated feed ingredients: AGM, its products of hydrolysis-extraction and purified amaranth pectin, on the erythropoiesis and growth performance in chickens were evaluated. It was demonstrated, A. cruentus pectin, contained in its phytomass as a protopectin or extracted from the phytomass as a soluble pectin have a stimulating effect on the erythropoiesis and positive effect on the liveability of chickens but does not affect their plastic metabolism. The promoting effect of AGM and its products of hydrolysis-extraction on the weight gain of replacement chickens is determined by the other biologically-active substances of non-pectin origin that are present in amaranth. Products of AGM hydrolysis-extraction enriched with pectin areconsidered as a new therapeutic and prophylactic feed additive that is much more effective than the raw materials used for their manufacturing. These products significantly increase the efficiency of chickens and improve their functional state that is indicated by the recuperation of erythropoiesis.
