The relevance of using non-traditional feed sources in feeding of pigs is becoming increasingly
important under the conditions of modern agriculture. In recent decades, there has been a signifi cant
decrease in the availability of traditional feeds, such as corn, soybean and sunfl ower meal, which is caused by an increase in their consumption due to the growth of livestock and poultry and climate change on the planet. Under such conditions, the search for alternative feed sources becomes necessary in animal husbandry. The purpose of the work was to increase the pork productivity of pigs through the use of amaranth
presscake in compound feed. Scientifi c research was carried out at the livestock enterprise TopAgro
LLC in the Gorodishchensky district of the Volgograd region. During the scientifi c and economic experiment
on young pigs 4 groups were formed according to the analogue principle per 45 heads in each. The
piglets were housed in rooms without a walking regime in special pens. The climate in the areas of their
maintenance was maintained automatically in accordance with the requirements of zoo and hygiene.
Animals were fed twice a day. Water was available around the day. The conditions of housing and feeding
of animals of all experimental groups were identical and corresponded to zoo and hygienic standards. The
main diff erence was in the pigs’ diets. Thus, the control group of animals received the main diet with 10 %
sunfl ower presscake. In the compound feeds of young pigs of the 1st experimental group 50 % of sunfl
ower presscake was replaced with amaranth presscake, in the 2nd experimental group this replacement
was 75 %, and in the 3rd group there was a complete replacement, which reached 100 %. The input of
amaranth presscake instead of sunfl ower presscake in the composition of compound feeds for young pigs
contributed to the gain in live weight by 2.38–5.17 %, carcass weight by 3.00–6.43 %, slaughter weight
and slaughter yield by 3.12–6.44 % and 0.54–0.94 abs.%, respectively. Thus, to increase meat productivity and pork quality of young pigs, we recommend input amaranth presscake into the compound feed recipe instead of sunflower presscake in an amount of 5 to 10 % of the compound feed weight.
