- W4221022911 abstract "The aim of the study was to study the effect of biological preparations: phytobiotics (pine needles), probiotics (Sporobacterin), immunostimulator Dorogov Antiseptic stimulator, fraction 2 (ASD-2F) on morphological blood parameters, safety and productivity of broiler chickens of the Cobb-500 cross. The studies were conducted on 4 groups of broiler chickens of the Cobb-500 cross, of which one is a control and three are experimental. During the first week of life, the bird of the 1st experimental group was added ASD-2F to drinking water; the 2nd-a decoction of pine needles; the 3rd - Sporobacterin. The chickens were raised from a daily age to 42 days old. It was found that the appointment of the above-listed biological products to chickens has a favorable effect on the morphological parameters of blood, increases the productivity and safety of livestock. The use of the drug ASD-2F led to an increase in the number of white blood cells on the 28th day of the chickens ' life to 22.9±1.32 x 109/l (p<0.01), red blood cells to 3.8±0.09 x 10 T/l (p<0.05), hemoglobin level to 120.3±0.33 g/l (p<0.01) g / l. On day 42, only the number of red blood cells increased to 3.76±0.05 x 10 T/l (p<0.01). The safety of the head was 95%, the absolute increase in live weight was within the control values compared to the individuals of the control group. When prescribing a decoction of pine needles, the number of white blood cells on day 28 was greater by 0.88 x109/l (p<0.01), an increase in erythropoiesis was noted on day 42 - an increase in the number of red blood cells by 0.61 T/l (p<0.05), the absolute increase in live weight by day 42 was 162.5 g (p<0.05) more than in individuals of the control group, the safety of the livestock was 100%. The inclusion of Sporobacterin in the diet did not have significant changes in the hematological parameters of blood, the absolute increase in live weight by day 42 was 106.14 g (p<0.05) more than in individuals of the control group, the safety was 95%." @default.
