Abstract
The article presents results proving the feasibility of extruded amaranth grain (Amaranthus cruentus) in feeding breeding laying hens of the Hisex Brown cross (aged 25-45 weeks). Due to improvements in the quality indicators of hatching eggs, such as weight (2.09%; P<0.01), Haugh units (1.07%; P<0.05), and shell thickness strengthened (5.0 µm; P<0.05) to 362 µm, it was possible to increase egg laying intensity by 1.81%, hatching egg yield by 2.20%, and hatching of chickens by 1.33% with the addition of 5% extruded grain to the diet structure. In the test group, there was an 11.66% (P<0.05) reduction in cholesterol in the yolk of eggs. The test group's hemoglobin concentration rose by 4.16% (P<0.05) in comparison to the control group's blood, while the test group's lymphocyte and segmented neutrophil levels decreased by 1.65% (P<0.05) and 1.93% (P<0.05), respectively. These results demonstrated the high efficacy of the feed under investigation in preserving the immune status of breeding chickens during the first productivity phase. The chicken body exhibited a high level of antioxidant activity as evidenced by the rise in superoxide dismutase activity by 8.85% (P<0.05), the total amount of antioxidants by 21.66% (P<0.01), and the decrease in malonaldehyde by 13.52% (P<0.05) in the test group. Analysis of the microbiome of the cecum in the colon revealed an increase in bacteria of Bifidobacteriales and Lactobacillales by 46.93 (P<0.01) and 25.54% (P<0.01), as well as a rise in Ruminococcaceae by 15.87% (P<0.01), in the test group compared with the control group.
