The use of alternative plant sources such as lupine grain, sorghum, chickpeas, mustard seed
products, rapeseed, amaranth can significantly reduce dependence on traditional feeds such as corn, soybeans and sunfl ower presscake. The input of alternative components into the poultry diet can not only
reduce production costs, but also increase resistance to feed price variability. The purpose of the research
was to study the eff ect of amaranth presscake in compound feed on egg productivity, morphological and
biochemical blood parameters of laying hens of the parent herd. The studies were carried out at the Svetly
enterprise located in the Svetloyarsky District of the Volgograd Region. During the scientific and economic experiment on laying hens of the parent herd 4 groups were formed according to the analogue principle per 100 heads in each. The hens were placed in battery cages manufactured by Big Dutchman throughout the experiment from 23 to 68 weeks. The conditions of housing the hens were identical and corresponded to zoo and hygienic standards. The control group received compound feed containing 15 % sunflower presscake. In the compound feed for the 1st experimental group of hens 50 % of the sunfl ower presscake was replaced with amaranth presscake, in the 2nd experimental group by 75 %, and for the 3rd experimental group sunfl ower presscake was completely (100 %) replaced with amaranth presscake. Feeding
amaranth presscake as part of the diet had a positive effect on the egg productivity of the hens of the experimental groups compared to the control group by 0.81–1.95 %. The average weight of an egg of laying
hens in the experimental groups was higher compared to the average weight of an egg of the hens-analogues of the control group by 1.36–2.07 %. The morphological and biochemical parameters of the blood
of the experimental hens varied within the physiological norm, which indicates the normal course of
oxidation-reduction processes. However, the input of amaranth presscake in the diet of adult hens of
the experimental groups contributed to the growth of some blood parameters such as erythrocytes by
1.54–7.18 %, hemoglobin by 0.18–1.77 %, total protein by 1.61–3.75 %, calcium by 2.82–5.46 % and
phosphorus by 3.95–9.21 % in relation to the control group. Thus, the input of amaranth presscake in
the diet of adult hens of the parent herd had a positive effect on metabolic processes in the body and had a beneficial effect on egg production.
